About Fremont HVAC Masters

A Fremont heating and air conditioning company since 2006, with a long record of connecting HVAC equipment to smart thermostats and home platforms.

  • Upfront pricing
  • Same-day service available
  • No overtime charges

Fremont HVAC Masters repairs, maintains and installs heating and air conditioning for homes in Fremont, Newark and Milpitas. We have worked in Fremont since 2006, from our office at 48501 Warm Springs Blvd, and from the start we have treated the thermostat and controls as part of the heating and cooling system.

Who we are

  • In Fremont since 2006.
  • More than 12,000 smart home integrations: thermostats, zoning and connected controls linked to the equipment they run.
  • More than 15 smart platforms supported, so the system can work with the app or voice assistant already in your home.
  • Licensed technicians. The company is bonded and fully insured.
  • EPA-certified technicians for work on refrigerant systems.
  • Factory certified parts only on our repairs.

What we work on

Most of our calls are everyday heating and cooling work: furnaces that will not light, air conditioners that run without cooling, heat pumps, ductless mini-splits, ductwork and indoor air quality. See all services and the brands we service. We are an independent service company, not affiliated with any equipment or thermostat manufacturer.

Where we differ is the controls side. A smart thermostat on a heat pump has to be set for the way its reversing valve is wired and told when backup heat may run. A zoning system has to keep enough air moving when only one zone calls. A variable-speed system may only use its full range with a control that can talk to it. Getting those details right is most of what makes a “smart” system worth having, and our smart home HVAC guides explain the basics.

What you can count on

  • Upfront pricing. You see the price before any work begins. No hidden fees.
  • Same-day service available. Same-day appointments are usually possible.
  • No overtime charges. Evening and weekend visits are not billed at overtime rates.
  • 90-day workmanship warranty on repair work; parts follow the manufacturer’s warranty.
  • Free in-home estimates for new-system installations.
  • 100% satisfaction guarantee. If you are not satisfied, we make it right.
  • Phone support 24/7.

No. We are an independent service company. We work on many brands of HVAC equipment and smart thermostats, but we are not affiliated with or endorsed by any manufacturer.

Do you only work on smart systems?

No. Most of our calls are ordinary furnace, AC, heat pump and mini-split repair, maintenance and installation. Smart thermostats, zoning and connected controls are an added strength, not a requirement.

Are your technicians licensed?

Yes. Our technicians are licensed and EPA-certified, and the company is bonded and fully insured.

What does the satisfaction guarantee mean?

If you are not satisfied with the work, tell us and we make it right. Repair work also carries a 90-day workmanship warranty.
