Heating, Cooling, and Electrical Work Built for Mountain View Homes
Mountain View sits on the flat valley floor, close enough to the Bay that evenings cool down quickly and winters stay mild. A heat pump covers the entire year here without a backup furnace. What actually decides how a system performs in this city is not the weather, it is the decade the house went up in. Mountain View kept more of its mid-century housing than almost any city its size in the valley, and those homes were designed around a heating approach nobody builds with anymore.
In Waverly Park, Monta Loma, and the other post and beam tracts there is no attic and no crawl space to route ducts through, the roof is low-slope, and the house was never built with a duct system at all. Plenty of these homes still have no cooling either. Boxing in the open beam ceilings to make room for ductwork destroys the thing that makes the house worth living in, so the answer is usually a multi-zone ductless system, with indoor units set along the ceiling line or high on interior walls where they stay out of the sightlines. Each zone gets sized on its own, because a room behind a full glass wall and a bedroom off the hallway do not carry the same load, and averaging the two is how these projects go wrong.
The ranch homes in Cuesta Park and Rex Manor do have ducts, though usually the original ones: undersized, leaking at the joints, and balanced for a gas furnace. Push a new high-efficiency system through them and most of what you paid for goes into the crawl space, so we test the ducts and redesign the layout where it earns its cost. Around Old Mountain View and Whisman the question changes again to condos and townhomes, where outdoor unit placement, sound, and clearance from the neighboring unit get settled during the estimate instead of on installation day. Ozone Service holds both the HVAC and the electrical license. That matters more here than it sounds. Moving to a heat pump rarely means a new electrical panel. We check yours during the free estimate and put the answer in writing. You should not be budgeting for something your house never needed.

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 Mountain View Homeowners
Replacing gas heating with an efficient electric system in Mountain View can qualify for rebates, and more than one program can apply to the same job. That is worth planning around in a mid-century home, where electrification usually happens in stages: the heat pump, the water heater, and the electrical work each open different doors, and doing them as one project often keeps more of those doors open at the same time.
Mountain View is served by PG&E and by Silicon Valley Clean Energy, the community energy provider for Santa Clara County cities. Local offers can stack on top of the larger statewide program running at the time.
Amounts and requirements shift through the year and depend on the specifics of your project, so we confirm what applies, install to the program requirements, and file the paperwork ourselves. Bring us in early, because eligibility for some programs is decided before the equipment is ordered.

Got a full heat pump system installed last month and honestly couldn't be happier with how the whole process went. From the first visit to final inspection, the team was organized and clearly knew what they were doing. What I didn't expect was how much help they gave me with the rebate programs - I had no idea how much money was available until Konstantin walked me through everything. They handled all the paperwork on their end, and my out-of-pocket ended up being significantly less than the initial quote. The system has been running quietly and efficiently since day one. Highly recommend to anyone in San Jose thinking about making the switch.Posted on Google![]()

AC stopped working on a Friday afternoon. Called Ozone, they came out the same day, found the issue fast, and had everything running before dinner. No drama, fair price. Thanks guys.Posted on Google![]()

Had a great meeting with Konstantin who explained "AC + furnace" vs heat pump, options, decision points. He presented impartially many technical and practical details and considerations that I find critical in making the right choices. Update: The heat pump installation was completed on time with no hiccups. Aleksander, the lead installer, was great in both the technical side but also explaining to me some very important details of the job and the future use. Definitely recommend them!Posted on Google![]()

We needed a completely new HVAC system installed, and we had a great experience working with this team. I’ll admit I’m pretty picky and detail-oriented when it comes to work being done on our house, especially during a major renovation, so I don’t give praise lightly. That’s part of why I wanted to write this review. Konstantine took the time to explain the product options and installation process very clearly, which made us feel confident from the beginning. He was always responsive and easy to reach — whenever we had questions or concerns, he picked up the phone, understood our situation, and worked hard with us to solve problems in a thoughtful and kind way. That level of care meant a lot to us. Since we’re doing a full house renovation, we later needed to relocate some HVAC vents and return locations that had already been installed. Even though this meant coming back to our house multiple times, they were incredibly kind and accommodating about making those changes for us. Special thanks to Alex for going above and beyond — we really appreciated his patience and help, especially since they had to come back more than three times for us. The whole team was professional, responsive, and genuinely cared about doing the job right. Even as someone who is pretty particular, I was very pleased with their work and highly recommend them to anyone looking for HVAC service.Posted on Google![]()

Frequently Asked Questions
Can you install air conditioning in an Eichler that has no attic and no ductwork?
Yes, we can. Ductless multi-zone systems were built for exactly this situation, and installing one does not require touching your existing heating at all. The only penetration is a small line set per zone, so the open beam ceilings and glass walls stay intact. Most of these installations are done in a day or two, depending on how many zones the house needs.
Where does the outdoor unit go on a flat-roof home with no side yard?
That gets decided during the estimate, not on installation day. On a low-slope roof there are usually two workable options, a ground pad in a screened corner of the lot or a roof mount with proper support and clearance. We check drainage, sound at the property line, and service access before we commit to either, so nothing gets improvised while the crew is already on site.
Our ducts are original from the 1960s. Do they have to be replaced with a new system?
No, not always. We check sizing, sealing, and airflow to each room during the estimate. If the ducts are sound, we reuse them. If they are leaking or undersized, we tell you what that costs you in efficiency and let you decide with the numbers in front of you.
Do you work on condos and townhomes where outdoor unit placement is restricted?
Yes, we do. Placement, sound levels, clearance from neighboring units, and any building rules are worked out during the site visit, so the plan you approve is the plan that gets installed.
