Improve Indoor Air Quality To Reduce Coronavirus Risk

Now that we’re spending more time indoors due to shelter-in-place, it is important that the air you and your family breathe is healthy and clean.

While there are several ways to limit your exposure to the coronavirus (hand washing, etc.), let’s focus here on how your home heating and cooling systems can play a role in a cleaner and healthier environment.

Upgrade Your Air Filters

According to the Center for Disease Control, the virus is mainly spread by large droplets in the air from coughing or sneezing. Your HVAC system’s air filters are the “face masks” of your home. They catch airborne particles but do not kill them. To reduce the risk of airborne exposure, consider upgrading your the air filters in your air conditioner and furnace. Higher density filters will trap airborne particles before they reach the air you breathe. Ask your HVAC contractor for the best air filter for your needs.

Change Your Filter More Often

A better air filter collects more particles. Especially when more of us are staying indoors, our filters will need to be replaced more often. If someone in your family is ill, consider changing your filters more frequently to minimize recirculating airborne particles.

Control Your Home’s Humidity

Keep your home’s humidity between 40-60% because viruses are least viable in this range. Several factors can improve your home’s humidity: installing insulation, installing a humidifier, and plugging leaking windows and doors. A skilled HVAC technician will conduct a thorough inspection and can recommend the best options to control humidity in your home so it remains within the recommended range.

Schedule an HVAC Assessment

A skilled HVAC technician will inspect your furnace and A/C systems for leaks and damage, checking your ductwork for proper alignment and ensuring it is fully sealed. Leaking ductwork forces your air conditioner and furnace to overwork, leading to higher energy bills. A well-maintained HVAC ductwork system traps indoor allergens in the air filters. They play a critical role in trapping allergens by trapping particles and preventing them from circulating through your home.

Why is my AC making noises!

Summer is around the corner. This means hot days are approaching and your AC will be needed to keep you comfortable in your home.

In addition to routine maintenance, check for any unusual or unexpected noises coming from your AC unit. These noises signal trouble with your unit and may require immediate attention. Here’s a guide to these noises and actions you can take:

Squealing From Blower Motor

Your AC unit’s motor may have a bad belt or bearing. You can replace the belt yourself if you choose since it is an inexpensive and easy task. This should be done as soon as possible since a bad belt can lead to a broken belt which will prevent the blower from turning. Also, if your motor unit has oil ports, you may want to change or fill the ports with motor oil to help soften motor noises. Always research appropriate oil before using as each motor will have its own specification.

Loud Rattling or Banging

These sounds typically originate from either loose fasteners on the metal cage or a component of the blower assembly or motor which has come loose. Loose fasteners require tightening screws or bolts that secure the cage. A more complicated problem will be if the problem is with a component on the blower assembly. If not addressed, this rattling will get louder and may result in the disconnection of the blower itself. As this is a more complicated issue, you may want to do more research before attempting to address the issue yourself. Or you may want to call a certified HVAC technician to fix the issue.

Clicking

Normally, your unit will click as it is being turned on and off but if the clicking is abnormally loud and coming from inside the cabinet, your capacitor may be on the way out and should be replaced. As a short term battery supply for the compressor and blower motor, the capacitor is a critical part of your AC unit and can wear down over time. An ineffective capacitor can put stress on the compressor which can in turn affect the overall health of your entire HVAC system. If you think your capacitor is making the clicking sound, turn off your AC unit immediately and contact a certified HVAC technician to replace the part.

Humming

If your AC unit does not turn on and your clicking sound has turned into a hum, this can be a very serious problem indicating the compressor is being used as a power source and can quickly lead to costly repairs. For this reason, we suggest that you turn off your AC unit to prevent further damage. These parts also have a tendency to fail during the warmest part of summer when your AC unit is working harder than normal. To avoid a breakdown, make sure to have a certified HVAC technician address this problem as soon as it is detected.

Loud Whistles or Screaming Noises

These types of noises are critical and can be very dangerous as they may indicate a refrigerant leak or internal pressure buildup. This needs immediate attention by a certified HVAC technician. If there is a 24-hour hotline for your specific technician, it is best to use that route as they may be able to diagnose the issue over the phone and provide next steps.

Metal on Metal

If this noise is coming from the fan, your blades may be the culprit. It is possible a foreign object like loose wiring or stones may be in contact with the blade. If not addressed, the blades may be damaged as well as the motor. This can even lead to a refrigerant leak. If you hear this type of sound, turn off your unit immediately and investigate what may be obstructing the blade(s). If the culprit can be removed manually, then cleaning and clearing the debris will fix the issue. A routine visual inspection of the fan and blades should be performed frequently while your unit is being used.

In summary, proactive and routine maintenance can help to prevent your AC unit from breaking down unexpectedly.

Why does AC installation cost so much?

When you think of installing a new AC, you think of it as an appliance. With a dishwasher, you purchase the model you want, get someone to install it, and — voilà — we are up and running. The cost of this is generally the labor cost of a handyman plus the cost of the appliance.

An AC is a part of the whole HVAC system of your house. So it is unhelpful at best, and disingenuous at worst, to publish a price range for installing an AC.

There are many factors that go into the cost of the installation of an AC. Here are some important ones.

The size of the AC

Unlike a dishwasher where you can determine the size of the dishwasher, you need a professional to evaluate the size of the unit for your house.

It is very important to get the size of the unit correct. If you get a bigger one, then the unit will turn on and off frequently resulting in wear and tear of the equipment. You will also spend your money in energy for this inefficiency. The biggest issue is that you are going to have comfort issues – noisy equipment, hot and cold spots in the house, etc.

If the unit is not sized correctly, your equipment will not be able to keep up with the demands of making your home comfortable.

Energy efficiency

SEER (Seasonal Energy Efficiency Rating) ratings measure the energy efficiency of an AC. Purchasing a higher energy efficient unit will be more expensive. In the long run though, it will cost you a lot less in energy bills. EER tells you miles/gallon about how efficient your equipment is. This has been tested in the factory’s controlled settings where they send this information to dept of energy to tell them how efficient this equipment is.

Duct work

Ducts are the tubes that carry the cold (or warm) air to the various rooms in your home. If you need to replace these, it will cost you a lot more. The cost of duct work varies depending on many factors, including the following:

Size of the home
Diameter of the duct needed
Material used
Design of the duct work
Space where the duct work will be installed

Number of vents & returns

These are the outlets for your duct where it either releases air into the house (vents) or pulls air into the duct (returns). You need vents in all the rooms and different areas where you need to feel comfortable. With each additional area/room to heat/cool, your installation cost goes up.

Zones and controls

Different areas in your home may need different types of heating/cooling. For eg., an upstairs room will be noticeably warmer than the room below because warm air rises. These 2 areas are considered to be in 2 different zones. So you will need separate temperature control upstairs and downstairs.

The more such localized controls you need, the higher your installation cost will be.

Permits

You will have to get a permit to install a whole HVAC system. In such a case, your contractor should be able to get a permit. Remember that the cost of the permit will be added to the cost of the installation. Once you get a permit, all these tests, including HERS, air leakage, static pressure, will be done.

Remember to compare apples to apples. Read your contract to find out what you are getting. Ask questions about how they came up with the design of the system.

MAKE SURE THE CONTRACTOR USES MANUAL J CALCULATIONS TO SIZE YOUR HVAC SYSTEM.

How to choose an HVAC contractor

Questions to ask your HVAC contractor

How to choose an HVAC contractor

When a heater or an air conditioner stops working or seems to have a problem, people tend to think that they need to replace it. Actually HVAC is a system as opposed to a single unit. If any part of the HVAC system isn’t working properly, you will not reap the benefits of the system. So you need to hire someone who can evaluate the whole system and make a recommendation.

There are many handymen who call themselves an HVAC contractor without the necessary credentials. All you need is a van/truck with a big signage on it and people will believe that you are an HVAC contractor. Hiring such a person in the short run could seem like a money-saving idea, but in the long run it could end up costing you more and create unnecessary and avoidable headaches.

Learn how to spot a good HVAC contractor who can help you keep your home comfortable for a long time to come.

Don’t consider someone who will quote you over the phone

When someone gives you a quote over the phone after listening to the issues you are having with your heating or air conditioner, it should be a warning sign for you. This person is probably not a licensed contractor.

An HVAC contractor will insist on coming to your house to check the ducts, registers, insulation, etc. They would do a thorough evaluation of the state of your HVAC system to give you an estimate. It is called a SYSTEM for a reason: it is not just a furnace or an air conditioner. If the supporting structures for these units don’t function well, you can have the best appliance and yet not be comfortable in your home.

When a contractor comes to your house to give you an estimate, be wary of someone who gives you an estimate by just looking at the appliances. Get 3rd party verification from Dept. of Energy (proper sizing of heating and AC) The genuine contractor will want to check the crawl space, attic, ducts, and survey the house before giving you an estimate. If they don’t do this, their estimate and their work could cost you more in the long run.

Select a contractor who is licensed by the Contractors State License Board

In the state of California, anyone who works on HVAC system is required by law to be licensed. The license allows you to manipulate gas lines and electrical & plumbing as it relates to HVAC. A person without sufficient knowledge could endanger much more than just the HVAC system. You may check for someone’s licence at https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx

Being licensed means that you have met a set of minimum requirements for the job, and now are authorized by the state to conduct business in that state.

Most importantly, if a contractor does a shoddy job, you can complain to the State License Board. If you hire a handyman to manipulate your HVAC system and if it ends up costing you more than necessary, you have only yourself to blame.

Get written estimate & warranties

As the saying goes, “The biggest fallacy about communication is that it has taken place.” A verbal quote is liable to be misunderstood or misinterpreted.

Your contractor should send you a written estimate of what the job entails and an estimate of what it would cost to do the work. Everything that will be done should be written down, including anything that will need to be bought.

This is important for 2 reasons. First, you can see if there’s something missing in your understanding of the work. Second, the estimate becomes a legal, binding contract that you can fall back on, if you need to take the contractor to court.

If they warranty parts or work, then you should get it in writing. Find out how long it will take them to come back and fix the issue.

Check the HVAC contractor online

Not only should you check the contractor’s license on the California State License Board, you should also research the contractor online.

Check out the contractor’s website. A website is a place where the contractor gets to present his skills and expertise. You will also learn about the person, how they work, and any testimonials from other clients. The website should certainly have his license on his website.

On websites like Yelp and Google, you should be able to see the kind of work this contractor has done for other people. You will also get a feel for the nature of the contractor – on time, tidy, honest, pays attention to detail, doesn’t talk much, etc.

Increasingly NextDoor is becoming a place where neighbors trust other neighbors’ experiences. These are great referrals because they have presumably used the contractor’s services. Unlike Yelp where you can get spurious reviews, NextDoor reviews are genuine and trustworthy.

Don’t pick a person because they quoted the lowest price

Is it tempting to pick the contract with the lowest bid? Yes!! Should you pick the contractor based on price? No!!!

Even though your urge may be to save a few dollars and pick the contractor with the lowest bid, you will be served much better going with a contractor who has the experience, track record of fantastic installations, and happy clients. Make sure you are comparing apples to apples; the higher price may be getting you better quality of work along with a better service.

Picking a contractor based on price alone could cost you a lot more in the long run.

Get a comfortable home and save yourself money by going with a licensed and trustworthy HVAC company.

Things to leave to your HVAC professional

DIY projects are popular after being cooped up in the house for so long. For the DIY person in you, it would be tempting to evaluate, install, or fix a malfunctioning furnace or air conditioner.

Unfortunately HVAC isn’t one of the house parts that you should fiddle with without detailed knowledge or HVAC training.

While you can certainly find sections of the HVAC system that you can evaluate for effectiveness, it is best to leave the installation and repair of air conditioners and heating systems to your local Redwood City HVAC professional. And here are a few reasons for that:

DIY on your AC or furnace could end up costing you more

HVAC systems may seem straightforward, but they are in fact, technically complex.

HVAC licensed contractors undergo training to evaluate, install, analyze, troubleshoot, and repair air conditioners, heaters, and air filtration systems in your house.

While it may be appealing to repair or install these systems yourself to save a few dollars, in the long run, it could end up costing you more.

In the worst-case scenario, you are endangering yourself with possible electrocution as well.

You may not have all the tools

Having the right tools is important for completing any project successfully. Heating & air conditioners are no different. HVAC appliances require the use of specific tools to repair an air conditioner or heating system. These tools are expensive and very specific to these jobs. These aren’t your regular screwdrivers.

If you have never taken apart an HVAC system, we’d highly recommend that you hire a professional qualified HVAC contractor for this work.

HVAC repairs aren’t for claustrophobes or arachnophobes!

AC and furnaces may be installed in very tight spaces which are accessible only by crawling inside. These spaces under the attic or under the house can be very small and constricting.

If your unit is installed in a similar tight space and you have a fear of closed spaces, call your HVAC technician to help you with it.

Attics and crawl spaces are also spaces that are enjoyed by rodents. If you have a fear of these animals, you may not want to tackle A/C or furnace repair yourself.

Since these areas aren’t frequently visited, they generally have a lot of spider webs. If you don’t like spiders and don’t like getting caught in webs, leave any furnace/AC repairs to the professional HVAC technician.

Warranty nullifies when you repair your HVAC yourself

If you tinker with your HVAC system, you could nullify the warranty that it came with. You don’t have to spoil the installation to void the warranty. The fact that you, a lay person, tinkered with the HVAC system could be enough to invalidate the warranty of the product or the installation.

This should be enough to convince you to leave HVAC work to a professional!

HVAC work may require permits

Since HVAC installation and repair work are highly technical, they may require a permit. Permit work requires that you hire a licensed contractor who has worker’s compensation and liability insurance. In case there’s an accident, the worker’s compensation would kick in, protecting you from a possible lawsuit.

HVAC work can also have EPA regulations governing them. These have to be adhered to for the whole process to be legal. If you are a weekend DIYer, you better know what you are doing.

If you aren’t aware of all the new regulations on HVAC, it is best that you call your local HVAC technician.

If you wish to give a cursory evaluation to your HVAC system before calling your HVAC technician, here are few articles that can help you with doing basic troubleshooting of your furnace or air conditioner:

6 ways to prepare your home for summer

Before you know it, the summer heat will be upon us. With a little bit of preparation, your home will be ready to keep you comfortable through the dog days of summer.

Turn your AC on early

Turning on your AC will allow you to find out if it is in working condition. If you hear the equipment cranking up, then it is working. Then go to each register in the house to make sure that cold air starts getting blown in within 5 minutes. If not, then there is a problem. Call your AC technician to schedule an appointment.

Change the filter

Filters clean the air of some impurities before that air is forced into the home. A cleaner filter means that the HVAC (Heating, Ventilation, Air Conditioner) will be able to move the air through the filter effortlessly. This leads to not only cleaner air, but also more energy efficiency leading to lower utility bills. A dirty filter, on the other hand, will make the HVAC work harder to push air through the filter leading to a higher utility bill and a stressed HVAC system.

Change the filter in the spring to help your AC running smoothly throughout the summer and check the air filter every month. If it is dirty, replace it.

Keep area around AC clean

AC works by pulling in air from its surroundings, cooling the air, and then forcing the air into the house through the ducts and vents. If the AC is installed outside the house, there should be at least 2 feet of clearance around the equipment. Make sure that there are no plants growing within 2 feet of the AC and clear out any yard debris from around the equipment to ensure proper air flow.

Do a visual inspection of the equipment, and if any coils look like they are frayed, then it is in need of repair. You may need to call your HVAC technician for help.

Close your windows

Curtains, blinds, and drapes are not only for aesthetics, but also serve a purpose. They block the harsh sun that can otherwise damage wood floor and furniture over time. They also help keep the house cooler by blocking the sun. A cooler house means that the HVAC has to do less work to keep the home comfortable, leading to a lower utility bill.

Clear and clean the registers

Make sure nothing is blocking the registers, such as furniture, drapes, and other items. Keeping the register area clear would enable the air to be better distributed in the room.

Over time, register grills can accumulate dust and grime. When the air is forced into the house, these get blown everywhere, which can affect people suffering from asthma and other respiratory ailments. Be sure to keep these grates clean with soap and water.

Schedule an HVAC tune-up

It is a good idea at the beginning of the season to get an HVAC technician to inspect your equipment to make sure there are no leaks or other damages. The technician should also be able to inspect your ductwork for proper alignment and to make sure that it is fully sealed.

Call us today at (650) 575-3915 to make an appointment. We’ll keep you cool and comfortable through the summer.

Should I repair or replace my HVAC system?

An HVAC system includes a furnace and/or air conditioner and the duct system to carry the air around the house.

In general, the lifespan of an HVAC system is between 15 and 20 years.

The lifespan of a furnace or air conditioer depends on how often the HVAC system was used, the quality of the mechanical components (furnace and AC), the quality of the furnace or a/c/ installation and the maintenance of the whole system over the years.

Here are a few considerations before you decide to replace your furnace or air conditioner.

Age of the system

HVAC systems last for up to 15 years. If the heating or cooling system stops working or the repair is going to cost a lot of money, then it is time to replace the furnace or air conditioning unit.

Safety

Old furnaces can get cracks in their heat exchangers. This enables carbon monoxide, a deadly gas that is colorless and odorless, to leak into the house. It is important to have a carbon monoxide detector to tell if your furnace has a leak.

Older HVAC systems could have compromised electrical issues. If fuses short or connections get weak, at the minimum your heating or cooling system will come to a halt. It can also cause fire.

Such safety issues are best mitigated by replacing the whole furnace or air conditioner.

Breakdown

An HVAC system that is over 12 years old will need to be replaced if there is a major breakdown. The cost of repairing a furnace or air conditioner can approach the cost of replacing it.

If the HVAC system is a fairly new one, but one of the major components needs to be repaired, then you will have to determine if the cost of fixing it approaches replacing the whole system. If yes, then you are better off getting a whole new HVAC system.

Degrading comfort level

There are 2 primary reasons for why your HVAC system is not keeping your home comfortable for you.

The first reason is that you have a wrong size of HVAC system installed in your home.

If the HVAC system is big for the home, the system is able to get your house to a comfortable temperature fast. This makes for a heating or cooling system that is turning on and off frequently leading to a stress on the system. If an AC doesn’t run for a certain length of time, it doesn’t dehumidify properly which is one of its core purposes. This also wastes energy and money.

If there is a leak in the ductwork of the furnace or air conditioner, you might sense a smell that is either putrid or not familiar. Leaky furnace or air conditioning ducts might also cause a decreased level of comfort in your home.

Increase in utility bills

An air conditioning or heating system that is steadily increasing your utility bills is indicating to you that it needs to be replaced.

An increase in bills means that the HVAC system is working harder and or longer to keep you comfortable in your home.

Smart Thermostats and HVAC

Why you need a smart thermostat

Having a good thermostat is very important to ensure your furnace and air conditioner are operating at maximum efficiency. You save both energy and money if your furnace and air conditioner are intelligently programmed.

For example, with a conventional thermostat you might set your desired temperature to 72 degrees. Then if you leave the house for 8 hours, your furnace is working to keep your house at 72 degrees when you are not even home. This is wasted energy and money. With a smart thermostat, you can turn the temperature down once you arrive at work. This enables your heating system to operate on low or even shut down while you are away. Then, when you are 30 minutes from home, you can use your smartphone to remotely set the temperature back to 72 degrees, turning the furnace on, so that you arrive home to a nice toasty house.

On a hot day, you can do the same thing with your air conditioning. Our HVAC experts can recommend and install a smart thermostat for you.

Be efficient with a smart thermostat

Smart thermostats, like Nest, have many advanced features, including letting you program your desired temperatures based on the day and time, plus controlling the temperature remotely via your smartphone. This works for both your heating and air conditioning systems.

How we can help

We can install a Nest thermostat for you for $575. This includes the Nest thermostat itself, installation, configuration, and a 5-year warranty. Plus, instead of just the 2-year warranty provided by Nest, we give you a 5-year warranty — and we’ll take care of the warranty issues for you, like getting a replacement. Call the HVAC technicians at RC Mechanical today. Homeowners in Redwood City and throughout the Bay Area count on us for all their heating and air conditioning needs.

Questions to ask your HVAC contractor

Before you hire a heating or air conditioning contractor, you need to know how they are going to do the work. Even if you don’t know anything about HVAC, you should be able to get a good idea of their work ethos with these questions.

1. How are you going to size my HVAC equipment?

Getting the right-sized equipment for your house and your needs is very important for efficiency and energy use. Why get a bigger and more expensive size HVAC equipment, when a smaller and less expensive one will do?

When it comes to an HVAC equipment, bigger is not better. If it is bigger, it will turn on and off frequently. This will significantly lower the life of the equipment.

One of ways to do the sizing of a furnace or air conditioner is by Manual J which is the protocol that is used to determine how much heating/cooling a home needs to stay cool and dry in the summer and warm in the winter.

2. How do you keep up-to-date on the current regulations?

The Department of Energy creates and revises its energy efficiency standards and other regulations. It is important for the HVAC contractor to stay on top of these regulations so your equipment and the installation meet those regulations. In extreme cases, it may be harder to sell your home unless the installations are up to code and it could run you thousands of dollars to bring a bad installation to code.

3. Who is going to do the work?

If the contractor is going to do the work, then he is going to do the best work he can. If he is going to hire other people to do the work, then the quality of the work will depend on the expertise of those workers.

4. If you are going to hire others to do the work, how are they paid? Hourly or by the job?

If the hired workers are paid by the job, they will try to finish the job ASAP to get to the next job. This could result in the job being rushed and the quality of the work could suffer.

5. What kinds of materials will you be using for the duct work? Will you be doing any custom fabrication for the furnace?

Many contractors use wire flex pipe. The advantage is that they are made of plastic and fairly inexpensive. Unfortunately these pipes are generally not installed correctly. Also, rodents could chew on these pipes!

Remember that you have an already existing furnace, then the HVAC contractor should do custom fabrication to ensure proper air flow without any leaks.

6. Are you going to look at the whole house for inefficiencies, determine the size of the equipment needed, installation, etc. or are you just going to sell me the equipment?

Does the contractor want to sell you a metal box aka furnace? If your house wasn’t getting heated or cooled properly because of a leaky duct, replacing the equipment isn’t going to solve the problem. So it is important for the contractor to evaluate the system you have in place instead of simply installing new equipment.

7. How are you going to determine that the system is running to its full capacity?

Your HVAC contractor should have a process in place where they show you how well the system is working.

8. Are you going to get the permit?

Any time you replace your furnace, the state requires you to get a permit. And it is the contractor’s responsibility to get the permit. The contractor is responsible to know the rules. A permit ensures the minimum requirement for the work is met.

9. Will you teach me how to do basic maintenance on the equipment?

Whether it is changing the filters or looking for issues, the contractor should give you instructions on how best to take care of your heating or air conditioning installation.

10. Are you and/or your company licensed and insured to work in my state/city?

Yes, there are companies and individuals out there who are not licensed to do any heater or air conditioner installations, but routinely do it. This puts you, your home and your family at risk for possible gas leaks, fires or pushing contaminated air into the house. Always ask to see your HVAC contractor’s license and liability and check their validity on your state government website.

Prep your AC for the summer

Check if your AC works before the summer season hits

Since the weather is still fairly cool, you may not think that it is time to worry about AC just yet. This is precisely the time you should!

It is important to make sure that your AC is working well before the summer’s hot days are upon us.

As a homeowner, prepare your AC for the summer months by first testing it yourself. If you are lucky, your equipment may have weathered the winter just fine.

Follow the 4 steps below to check if your AC is ready for the summer.

1. Physical inspection

This involves physically looking at the AC equipment and clearing the dust, leaves and other debris around it. Clear out cobwebs and dirt from around it. You may also use your hose to give the equipment to clean the exterior of the AC. Check for any missing panels.

Change your air conditioner’s filter at the beginning of the season.

2. Turn system on

Before you turn the AC on, visually ensure that the electrical wiring is not damaged.

Turn the AC on. If it starts, hooray! If not, check to see if the equipment is plugged in!! The air conditioner’s plug could have gotten accidentally dislodged from the outlet.

Make sure all the the circuit breakers and fuses are in place and turned on.

Also, set the thermostat to ‘cool’ and make sure that the thermostat is working properly.

3. Check the ducts

Air conditioning ducts carry the cool air from the AC to all the rooms. Ducts are hidden from view. The way to check the ducts is to find out if the air is coming out of all the registers in the house. Initially the air may not be cool and that is ok. At this point, we are just checking to see if the air is coming out of all the registers in the house. If it is, then the ducts are working well.

If the air doesn’t come out the register with the same force as in the other registers, then we may have an issue with the ducts. Call your AC contractor.

4. Check the temperature

The last step is make sure that the AC is actually pushing cool air. You can use a regular meat thermometer for this.

After 30 minutes of running the AC, the temperature of the air being pushed at each of the registers should be 55 degrees. If it is not, then your AC may be low on freon or there may be some other issue with the AC.

Summer days will be here soon enough. Make sure you are ready for them with a well-maintained and efficient air conditioning system.
