If the ductwork has no leaks, you never need to clean your ducts!

Our top priority is your health and safety. That’s why we’re taking extra care in reducing risk to you and your family through these safety procedures.

Spring cleaning often includes a deep clean of your home. Sweep out the gutters. Check for leaks and water damage. How about cleaning your air conditioning and furnace ducts? Surely getting your ducts spic and span will promote healthier indoor air, right? Not so fast.

The US Environmental Protection Agency recommends getting your air ducts cleaned only in special situations:

  • If there is mold growth inside ducts
  • If the insulation in your air ducts get wet or moldy
  • If ducts are infested with rodents or insects
  • If ducts are clogged with excessive amounts of dust and debris

What should you do instead? First, diagnose the problem properly.

At RC Mechanical, we focus on fixing the root problem with your A/C or furnace, not just the symptoms. We address the underlying causes of A/C and furnace issues. Otherwise the problem will recur and cost you more money. You may end up installing a new A/C or furnace unnecessarily. And addressing the underlying problems starts with a thorough inspection.

Schedule an HVAC Assessment

Getting a thorough assessment of your furnace and air conditioner will determine if you need your ducts cleaned or replaced. If there is excess debris in your ducts, chances are this is caused by a leak in your HVAC ductwork. We will conduct a thorough inspection of your furnace and air conditioner to identify the root problem before recommending the best solution for your situation.

If the ductwork has no leaks, you never need to clean your ducts! Cleaning them will unnecessarily blow dust particles into your home.

The EPA also recommends preventing water and dirt from entering the A/C or furnace system as the first priority. It is more important to look for leaks than for dust in your ductwork system. A leaking ductwork forces your air conditioner or heating system to overwork which can lead to higher energy bills.

A well-maintained A/C or furnace ductwork system traps indoor allergens in the air filters. This reduces allergens by trapping particles and preventing them from circulating through your home.

If Your Ducts Do Need Cleaning or Replacing

If an HVAC inspection uncovers mold, rodents, or excessive amounts of dust in your ductwork, this could require cleaning or replacing your ducts.

When hiring an HVAC contractor, ask that they provide you with before-and-after photos of the ducts so that you have assurance that the ductwork does have a problem(s) and that the problems have been fixed.

Ensure that the HVAC contractor cleans ALL components of the heating system or air conditioner, not just the ducts. Failure to clean one component can contaminate your entire air conditioner or heating system. This would erase any benefit your HVAC system received from the duct cleaning.
