Our Services
Heating, Cooling, and Electrical Work Built for Los Gatos Homes
Los Gatos is really two towns for anyone who works on HVAC. Down in the flats there are homes from the 1890s and 1920s with plaster walls, small footprints, and nowhere ducts were ever meant to go. Up along Shannon, Kennedy, and Blossom Hill there are large multi-level houses spread across a slope, under heavy oak canopy, with afternoon sun hitting one side while the other holds shade all day. The same system specification will not serve both, and the distance between them is wider here than in any neighboring city.
Hillside homes fail in a predictable way. Heat stacks upward across three levels, so a single thermostat on the middle floor leaves two thirds of the house uncomfortable. Duct runs out to the far bedrooms are long, and by the time air arrives the temperature has drifted. A west-facing room on the ridge and a canyon-side room on the same floor are not the same load. The answer is almost always zoning, either a zoned ducted heat pump with proper dampers and separate thermostats, or a multi-zone ductless system where the layout will not take ducts at all. The site matters as much as the equipment here: slope, clearance around the condenser, service access in five years, how visible the unit is from the house, and how much oak debris ends up in the coils all get settled during the estimate rather than improvised on install day.
Near Tait, Bachman, and Broadway the problem inverts. Homes built before 1930 have no ductwork, limited wall cavities, and interiors worth protecting, which makes ductless the natural fit since each zone needs only a small line set penetration and gets its own control. Older properties are also where aging electrical service genuinely shows up, so we look at it early rather than late. Even in these houses, moving to a heat pump rarely calls for a new panel, and because we carry both licenses we can settle that question during the free estimate instead of sending you to a second contractor for the answer.

Why Homeowners Choose Ozone Service
Rebates & Incentives for Bay Area Homeowners
Ozone Service has secured over $500,000 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.
Written Warranty on Every Job
HVAC installation labor is covered for 3 years and can extend up to 12 years with annual maintenance. Electrical work carries a 1-year labor warranty, and equipment is covered by its manufacturer. One team, one contract, everything in writing.
Emergency HVAC & Electrical Service
AC failed? Furnace out on a cold weekend? Electrical issue that can’t wait? Our team offers same-day service in most cases, with the same technicians and the same quality on every call.

Rebates and Incentives for Los Gatos Homeowners
Switching from gas to efficient electric heating and cooling in Los Gatos can qualify for rebates, and several programs can be combined on a single project. On a larger hillside home the scope is usually bigger to begin with, a zoned system, often a water heater, sometimes electrical work alongside it, and a bigger scope generally means more than one program is in play.
Los Gatos is served by PG&E and by Silicon Valley Clean Energy, the community energy provider for Santa Clara County cities, and local offers can be layered on top of the statewide program in effect at the time.
Program budgets and rules change during the year and depend on what you are installing, so we check eligibility for your project, make sure the installation meets the requirements, and handle the documentation. The earlier you ask, the better, since some programs are decided before equipment is ordered.

Absolutely fantastic service! Cannot thank Ilya enough. He literally saved us! Climbed up into that attic, worked his magic, and voilà >> our heater is working doing its job again and the house is warm! Super responsive, professional, and clearly knows his craft. Couldn’t recommend Ilya more. Thank you for saving us from freezing! :)Posted on Google![]()

AC unit in my condo stopped working, Ozone service was the only company that provided a free diagnostic. They diagnosed the issues and I ended up opting for a complete HVAC system replacement due to my broken/malfunctioning unit being 40+ years old. They sent me several estimates with different units and I picked one and scheduled the replacement. Job was scheduled within one week and completed within one day, amazing turnaround time.Posted on Google![]()

Update: It took almost six months and repeated follow-ups from us before the contractor finally contacted the city inspector and got the permit finalized. While we appreciate that the issue was eventually resolved and we understand it’s an administrative oversight by city, it should not have taken six months and so much effort on our part to get something as basic as permit closure completed. When hiring a contractor, we expect not only quality installation work but also proper project management and accountability through the entire process as the permit application is fully handled and coordinated by the contractor. Unfortunately, the lack of follow-through significantly affected our overall experience. I hope the company takes this feedback seriously and improves its post-installation support. Initial review: We just had them replace our duct and add Gree AC heat pump in San Mateo. Happened to have a factory-defective TXV in the beginning but they acted fast to replace a new one. You’ll know why they have all 5-star on google. Already shout out their name to all my friends. Hope they grow their business while keeping the best service and price. Then we would hire them to update everything again after a decade.Posted on Google![]()

Great experience during a heatwave! Ilya arrived right on time, quickly diagnosed the AC issue, and explained that my parts were covered under warranty. He also gave me clear advice on potential future issues with my overall system. Very honest, knowledgeable, and punctual. Highly recommended!Posted on Google![]()

Frequently Asked Questions
Can one system handle a three-level hillside home?
Yes, it can, but only if it is zoned. A single-zone system on a multi-level house will always favor one floor. We run the load level by level and design either a zoned ducted system with separate thermostats or a multi-zone ductless setup, so each floor holds its own temperature instead of borrowing from the others.
Can you install a heat pump in a home built in the early 1900s with no ductwork?
Yes, we can. Ductless systems suit these houses well because installation requires only a small line set penetration per zone, so plaster walls and original interior detail stay untouched, and each room gets its own control.
Does a steep lot or hillside access change the installation?
Yes, it does. Slope affects where the outdoor unit can sit, how it drains, how clear it stays of oak and leaf debris, and how easily it can be serviced in five years. We work all of that out during the site visit, and the written estimate reflects it rather than turning into change orders halfway through.
Will switching to a heat pump mean a new electrical panel in an older Los Gatos home?
No, usually it will not. Homeowners assume it does, and most of the time that turns out to be wrong. We calculate the actual load, and where capacity is tight there are often options that cost far less than a full panel replacement. If an upgrade really is needed we tell you why, and our own electricians do the work under the same contract.
