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.

Frequently Asked Questions
Do I really need an electrical panel upgrade to install a heat pump?
Not always — but often. A heat pump draws significantly more power than a gas furnace, and many Bay Area homes have panels that were sized before modern electrical loads. We assess your existing panel as part of the estimate. If an upgrade is needed, we handle both scopes in-house under one contract. If it’s not needed, we’ll tell you that too.
Do you provide 24/7 emergency services for both HVAC and Electrical?
Yes. An operator is available around the clock to take your call and schedule a technician. We cover both HVAC and electrical emergencies — the same licensed team, not a subcontracted after-hours crew.
Are you licensed and insured to work in Santa Clara and San Mateo Counties?
Yes. Ozone Service holds CSLB license #1128892, is fully insured, and operates across Santa Clara, San Mateo, and Alameda Counties. All installations are permitted through the relevant city or county building department and pass inspection before the job is closed out.
How long does a typical heat pump installation take?
Most heat pump installations are completed in 1–2 days. Projects that include ductwork replacement or electrical panel upgrades may take longer depending on scope — we give you a specific timeline during the estimate, not after the work starts.
Do you offer truly free estimates and diagnostics?
Yes — no trip fee, no diagnostic charge, no obligation. We assess the system, identify the issue, and give you a written scope and price. If you decide not to move forward, you owe nothing.
Which equipment brands do you install?
We work with Goodman, Daikin, Mitsubishi, Carrier, Trane, Lennox, Rheem, Reclaim, and Sanden. We recommend the system that fits your home and budget — not the brand with the highest margin for us. All installed equipment is covered under our up to 12-year parts and labor warranty.
