Heating, Cooling, and Electrical Work Built for Campbell Homes

Campbell grew out of orchards in the 1950s and 1960s, and most of the city still lives in the single-story ranch homes that replaced them. They are easy houses to work in, but they share the same weak points: a furnace in the garage or a hall closet, ducts in a low attic or crawl space that have never been replaced, and a panel that was sized before central air, an EV and a kitchen full of appliances. We go through all three before we recommend equipment, because the right unit on the wrong ducts is still the wrong system.

Around downtown and the Alice Avenue area the houses are older, some from the 1910s through the 1930s, and many have been added onto over the years. Ductwork there is often a patchwork, and some rooms were never on the system at all. Ductless units for the additions, a properly sized central system for the original house, or a full redesign are all on the table, and we tell you which one fits before you commit.

Summers in Campbell run hotter than on the Peninsula, so cooling is not an afterthought here. We size every furnace and air handler so the same blower can carry a correctly matched AC or heat pump, and we check the ducts for the extra airflow summer needs. Winters are short but cool enough that heating still has to work, and a heat pump covers both seasons from one unit.

Why Homeowners Choose Ozone Service

Ozone Service has secured over $500,000 in rebates in the past 6 months. We help homeowners in Santa Clara and San Mateo Counties 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, and 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, with 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.

Same-Day HVAC & Electrical Service

AC failed? Furnace out on a cold weekend? Electrical issue that can’t wait? We offer same-day service in most cases. Same technicians, same quality on every visit.

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! :)

 Trustindex verifies that the original source of the review is 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.

 Trustindex verifies that the original source of the review is 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.

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!

Frequently Asked Questions

Should I replace my furnace and AC at the same time in Campbell?

It depends on their age, but often yes. A furnace and an AC share the blower and the ducts, and when one is near the end of its life the other usually is too. Replacing them together lets us match the two, size the ducts once and pull one permit instead of two. If the AC is still young, we install a furnace that is compatible with it and leave the AC alone.

Is a heat pump a good fit for Campbell summers?

Yes, it is. A heat pump is an air conditioner that also runs in reverse for heating, and the cooling side is built for exactly this climate. On hot afternoons it performs the same as a standard AC of the same size, and in winter it replaces the furnace. The one thing it needs is correct sizing, which is why we start every estimate with a load calculation.

My 1950s Campbell home has the original ductwork. Does it need to be replaced?

Not always. We measure what the ducts can actually deliver against what the new system needs. If the gap is small, sealing and a few fixes are enough. If the gap is large, or we find crushed runs, missing insulation or rodent damage, we recommend replacement and show you why on the spot.

Do you handle permits and inspections with the City of Campbell?

Yes, we do, on every installation. We file the permit before the work starts, schedule the inspection and pass it before we close the job. You do not deal with the building department at any point.
