Heating, Cooling, and Electrical Work Built for Menlo Park Homes

Most of Menlo Park was built in two waves, and each one asks for a different approach. The ranch homes of the 1940s and 1950s in the Willows, Suburban Park, Flood Park and Linfield Oaks were built on slabs or low crawl spaces with small furnace closets and ductwork that was sized for a different era. In those homes we start with the ducts and the closet, not the equipment. A new system that pushes more air through old, leaky runs will not feel like an upgrade. Where the ducts can be reused we reuse them, and where they cannot we design a new run before we pick a unit.

Sharon Heights and West Menlo Park are a different story. Larger homes from the 1960s and later, often on two levels, with a bigger footprint and more rooms to balance. Here the job is usually zoning, airflow balance and a load calculation that accounts for the whole house, including an ADU, a workshop or an EV charger that was added later. In most of these homes the existing electrical panel has room for a heat pump once we check the real load, and when it does not, we handle the electrical side in-house.

Closer to the bay, mornings stay cool and damp well into spring, so heating runs more months than visitors expect. A properly sized heat pump handles that comfortably, and it also covers the handful of hot afternoons the area gets each year. We size for both, not just for winter.

Why Homeowners Choose Ozone Service

Rebates & Incentives, Paperwork Included

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.

Rebates and Incentives for Menlo Park Homeowners

Menlo Park homes get gas service from PG&E and electricity through WestLight Energy, the community energy provider for San Mateo County. Replacing gas heating or a gas water heater with a heat pump is where most incentives apply, and more than one program can apply to a single project.

Programs change during the year and some require an application before the work starts, so the order matters. Call us first, tell us what you are planning, and we will confirm what is open for your address, make sure the installation qualifies and handle the paperwork.

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.

 Trustindex verifies that the original source of the review is 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!

Frequently Asked Questions

Can a heat pump work in an older Menlo Park home that has no ductwork?

Yes, it can. Many homes in the Willows and Allied Arts still have wall or floor heaters and no ducts at all. In those homes a ductless system with an indoor unit per zone is usually the cleanest fix, with no attic work and no new ductwork. If you would rather have central air, we look at whether a compact ducted system can fit the attic or crawl space before we recommend either option.

Do you pull permits with the City of Menlo Park?

Yes, we do, for every installation. We file the permit, schedule the city inspection and pass it before the job is closed. A permitted and inspected system is also what the manufacturer and the rebate programs expect to see, so skipping it costs more later than it saves now.

Will I need a panel upgrade to add a heat pump and an EV charger?

Not in most cases. Most Menlo Park homes have a 100 or 125 amp panel, and a load calculation usually shows enough room for both. Where it is tight, a power management device lets the two share capacity without replacing the panel. We check this during the free estimate and give you a written answer before you commit.

Why does my Menlo Park home feel damp in the morning even with the heat on?

Usually because the system is cycling too briefly to move enough air. Cool, damp mornings near the bay are normal, and a furnace or heat pump that is oversized for the house heats the thermostat quickly and shuts off before the air in the rooms has turned over. Correct sizing and balanced airflow fix most of it. If the problem is in a crawl space or an unsealed return, we find that during the assessment.
