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.
24/7 Emergency HVAC & Electrical Service

Called OZONE late Friday night and had Andrew out by 8am Saturday. He diagnosed the failed starting component quickly, had the part on the truck, and had the system running and verified cold before he left. On time, no upselling on a old unit, one-year warranty on the repair. Exactly what you want from a service call. Highly recommend.Posted on Google![]()

Frequently Asked Questions
Do I really need an electrical panel upgrade to install a heat pump?
No, in most cases you do not. Most Bay Area homes can run a heat pump on the existing panel. We check your panel as part of the free estimate and help you avoid an unnecessary upgrade. 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, we are. Ozone Service is licensed and insured and works throughout Santa Clara and San Mateo Counties. Every installation is permitted through the relevant city or county building department and passes 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, we do. There is no trip fee, no diagnostic charge, and 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 carries the manufacturer’s warranty, and our installation labor is covered in writing.
