Our Services
Heating, Cooling, and Electrical Work Built for San Mateo Homes
San Mateo sits on the Peninsula, close to the bay, where the marine climate keeps summers milder and winters damp and cool. That climate makes an efficient heat pump one of the smartest upgrades a local homeowner can make, delivering steady heating through the wet winter months and reliable cooling on the warm days without the swings you’d see further inland. The key is sizing the system to your home’s actual load, not a rule of thumb, which is where a lot of installations go wrong.
Ozone Service handles both the HVAC and the electrical side under one roof. That matters in San Mateo, where the housing stock runs from established older homes to newer construction, and the right upgrade depends on what your home already has. Switching to a heat pump rarely requires an electrical panel upgrade, and we assess your panel during the free estimate so you only pay for work your system actually needs.
One licensed team manages the full scope, from system selection and installation to any electrical work and the rebate paperwork most contractors leave to you.

Why Homeowners Choose Ozone Service
Rebates & Incentives for Bay Area Homeowners
Ozone Service has secured over $350,000 in rebates in the past 6 months. We help Bay Area homeowners reduce the cost of upgrading to energy-efficient heating and cooling systems. Depending on your location, utility provider, and equipment selected, you may qualify for valuable rebates and financing programs. We handle the documentation - most contractors don't.
Free Estimates & Free Diagnostics
No trip fee. No diagnostic charge. We assess the full system, identify the problem, and hand you a written scope and price before any work begins. After fixing a compressor for one of our clients, Tim checked the rest of the system at no extra charge to rule out downstream issues. That's not exceptional - that's how we work.
EPA 608 Certified & BBB Accredited
Handling refrigerant the right way matters. Our EPA 608 certified technicians follow strict standards for refrigerant recovery, leak prevention, and system charging - helping protect the environment while keeping your HVAC system efficient and reliable. BBB Accreditation means there's a paper trail and accountability if anything falls short.
HVAC + Electrical Under One Roof
Heat pump installations require both HVAC and electrical work. Because Ozone Service is licensed in both trades, we provide complete in-house service from start to finish - no need to coordinate multiple contractors. From equipment installation and wiring to permits and final testing, everything is handled under one roof for a smoother, faster project.
Up to 12-Year Warranty on Parts & Labor
We put up to 12 years on both parts and labor in writing - because a system installed correctly shouldn't need to be touched. If your home needs a panel upgrade or additional electrical work as part of the project, that's covered under the same warranty. One scope, one guarantee.
24/7 Emergency HVAC & Electrical Service
AC failed at midnight? Furnace out on a cold weekend? Electrical issue that can’t wait? Our team responds around the clock — same technicians, same quality, any time of day or night.

Rebates and Incentives for San Mateo Homeowners
Upgrading to efficient electric heating and cooling in San Mateo can qualify for significant rebates, and the programs stack, so a local incentive can be combined with the main statewide program to bring your out-of-pocket cost down.
On top of that, San Mateo homeowners have access to local rebates through PG&E and WestLight Energy, the Peninsula’s community energy provider, and those programs can stack with other available programs at that time.
Rebate amounts and requirements change and depend on your specific project, so we confirm which programs apply, make sure your installation qualifies, and handle the documentation.

What Our Customers Say
Frequently Asked Questions
Do you serve all of San Mateo and nearby cities?
Yes, we do. We work throughout San Mateo and the surrounding area, including Redwood City, San Carlos, Portola Valley, Menlo Park, Millbrae, Burlingame, Hillsborough, Foster City, and Belmont, as well as the wider San Mateo County. If you’re not sure whether you’re in our service area, call us and we’ll confirm.
Which rebates can I use for an upgrade in San Mateo?
Is a heat pump a good fit for San Mateo's climate?
Yes, it is. San Mateo’s mild, marine-influenced winters and moderate summers are well suited to heat pumps, which deliver both efficient heating and reliable cooling from a single system. A properly sized heat pump runs efficiently year-round and typically costs less to operate than a gas furnace paired with a separate AC.
Do you handle both the HVAC and the electrical parts of an upgrade?
Yes, we do. We’re licensed for both HVAC and electrical work, so a single team manages the whole project, including any dedicated circuits or panel work if your system needs it. That means one point of accountability and one warranty covering the full job.
