From Our Website

RC Mechanical is more than a heating and air-conditioning contractor - we are a "Whole House Performance" contractor. Using state-of-the-art software, we evaluate your whole house. From there recommend ways to make your home more comfortable and efficient - getting you the BEST heating and cooling results while at the same time lowering your carbon footprint. RC Mechanical is a veteran-owned HVAC business in Redwood City, California and has served the Bay Area with integrity for 20+ years. We pride ourselves on our on-time guarantee, clean and friendly HVAC technicians, and straightforward pricing.

Sal Contreras, a U.S. Army veteran, started RC Mechanical Inc. in Redwood City, California in 1992. Sal is a highly trained building-trade journeyman who knows how to turn a flat piece of metal into something useful. He has been doing sheet-metal work since high school and worked with sheet metal on helicopters in the service. Even with all this experience, Sal still makes time to take yearly training to keep up with the advances and best practices in the industry. His immense attention to detail ensures you get top-notch results.

Poorly designed or maintained heating and cooling systems can create health risks in your home, such as dust, allergens, mold, gas vapors, and carbon monoxide. Our diagnostics include a Door Blower Test - this will find all the air leaks in the home and also in the heating system. Air leaks from the attic, crawlspace, and garage are the worst kind because they bring dirty air into your home. We're also experts in the latest high-tech air filtration systems. At RC Mechanical, a local Redwood City, California business, we can address these issues and make your home a healthier place.

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.

My air conditioner was on the fritz, and after 3 days of calling other businesses and getting NO returned phone calls, the fact that Sal called me back in 1/2 hour was a relief. He was here the next morning and quickly discovered my system had a freon leak. He fixed it, and in the process, took the time to inspect my whole HVAC system as well as the rest of the house and he made great recommendations for improving the temperature control inside the house. He takes the time to talk with his clients and explain things clearly.
