“Sal has been our go-to guy ever since we put on a second floor addition twenty years ago here in Palo Alto. He knows what he is doing, makes a point of being up-to-date on all the best systems, is honest, fair, and doesn’t try to sell you anything you don’t need. He has our complete vote of confidence!

– Virginia, Palo Alto

“I give Sal Contreras at RC Mechanical my highest recommendation. We’ve done extensive remodeling, with various contractors. Working with Sal was probably the best decision we’ve made for our house. He works hard, finishes on time, explains everything along the way and REALLY, REALLY cares about doing a quality job.”

– Melissa, Sunnyvale

“We enjoyed working with you and would unconditionally recommend you to anyone needing heating or cooling system services. You were always clear as to what we could expect in terms of work and costs and went the extra mile to deal with the unique conditions presented by our older house. Please refer anyone to us wishing to know more about you and your work.”

– Tom & Linda, Foster City

“You will NEVER find a better HVAC expert than Sal. I found Sal after developing a severe allergy to my cats. Sal conducted extensive air pressure testing (for free!) in order to diagnose where we had leaks and why our air quality was so poor.

“Sal diagnosed our problem immediately—a combination of an improperly sealed furnace that was pulling dust from our cat litter into the air ducts (!!!), the installation of cheap ductwork made from plastic flex (which collects dust in the grooves), and the total failure of an expensive electrostatic/UV air filter that came highly recommended by the HVAC guys who never sealed our furnace.

“Not one of the many other HVAC guys I called to diagnose our air quality problems (before finding Sal) mentioned any of these things. No one conducted air pressure tests. Nobody mentioned ductwork. No one even bothered to open our furnace, the inside of which was plastered with cat hair and litter. (When Sal opened our furnace, I almost fainted).

“We hired Sal on the spot to clean up this mess of a situation. Best money I have ever spent.”

– Nyla, San Mateo

“Sal is a great resource. I had called two others but could not schedule a visit for 1-2 days. I called Sal and got his voicemail. I went back to adding wood to the fireplace for some more heat and Sal calls back. We spent 1/2 hour on the phone as he diagnosed that we actually had several problems. He showed up an hour later (7:30 pm) and stayed 1.5 hours until he had a temporary fix in place. He then gave me a quote to correct the furnace and its piping (which had only been installed a year ago, but with small errors that added up to it stopping work).”
