What heating and cooling work do we do in Milpitas?
We handle the whole system, from a quick repair to a full replacement. Milpitas is our home base. These are the services Milpitas homeowners call us for most:
- Cooling, including AC repair when the system runs but the house stays warm.
- Heating, including heat pumps that heat and cool with one system.
- Water heaters, including heat pump water heaters.
- Indoor air quality, plus duct repair and replacement for older, leaky ductwork.
Which rebates can Milpitas homeowners get for a heat pump?
You may qualify for a rebate from Silicon Valley Clean Energy (SVCE), and Milpitas residents may get a little more on top. SVCE is the not-for-profit electricity provider for Milpitas and a dozen other Santa Clara County communities. As of November 2026, its home rebates page lists rebates for:
- A heat pump heating and cooling system that replaces a gas furnace or an electric resistance heater.
- A heat pump water heater that replaces a gas or electric resistance water heater.
The same page says the City of Milpitas funds extra rebates for some of this equipment. You get the city amount through SVCE’s standard application, with no extra steps. City funds last only until they run out. You may qualify; call us and we’ll check what applies to your home.

Who pulls the permit for a new system in Milpitas?
We do. A new furnace, AC, heat pump or water heater in Milpitas goes through the city’s One-Stop Permit and License Center on the first floor of City Hall. The city’s Building team issues permits for repairs, remodels and changes to homes, then inspects the finished work. We file the permit, meet the inspector and arrange any HERS testing the system needs. HERS testing is a separate check, by a certified rater, that the ducts and refrigerant charge meet state energy rules.
What have we worked on in Milpitas lately?
One recent Milpitas job was an AC that ran but no longer cooled well. The technician confirmed the system was low on refrigerant, added R-410A and checked the pressures until it cooled properly again. You can see it in our Milpitas AC recharge project. We have also written Milpitas guides on AC warning signs before a heat wave and air duct replacement.
What do Milpitas homeowners ask us?
Can you look at my system before summer starts?
Yes. An AC tune-up is $135. Comfort Club Full covers two visits a year, one for heating and one for cooling, for $18.95/month or $225/year.
Is my old furnace worth replacing with a heat pump?
Often it is, especially while rebates are open. We look at the age of the furnace, the ductwork and your electrical panel, then give you a free written estimate.
Can you install the same brand I have now?
Yes, if that is what you want. We install any brand, and we will also explain how other options compare for your home.
Why do Milpitas families call a local company?
We live and work here. Upgrade Home Services is a family-owned HVAC contractor that opened in Milpitas in 2002 and still runs from the same city, at 743 Ames Ave. We hold California license CSLB #1066776 (B, C-20). We install whichever brand you prefer, including Amana, Carrier, Daikin, Goodman, Mitsubishi and Payne. From Milpitas we also serve the rest of our 22 cities across Santa Clara, San Mateo and southern Alameda counties.
Key takeaway: Milpitas homes buy electricity from SVCE, and the city adds money to some SVCE heat pump rebates while funds last. We pull the Milpitas permit, handle HERS testing and give free estimates on new systems.
