About Ozone Air Conditioning & Heating

Ozone Air Conditioning & Heating repairs heating and cooling systems for homes in and around Santa Clara. Our approach is simple: find out what's actually wrong, explain it in plain terms, and help you decide what makes sense for your house and your budget. We'd rather fix the system you have than sell you one you don't need.

Diagnosis comes before any recommendation

A furnace that won't light or an air conditioner blowing warm air can have a dozen possible causes. Some are small, like a failed capacitor, a dirty flame sensor, or a clogged condensate line. Others are bigger. We test before we guess, so the repair matches the real problem.

Once we know what's going on, we walk you through it. You'll hear what failed, why it likely failed, what your options are, and what we'd do if it were our home. If a repair is reasonable, we'll say so. If the system is near the end of its useful life, we'll explain why and let you make the call.

• We explain the problem before we start the work
• We tell you when a repair is the better choice than replacement
• We point out wear we notice so you can plan ahead
• We clean up and leave the equipment area as we found it

Built around how homes here actually run

The Santa Clara Valley has dry summers and mild, damp winters. Inland and southern parts of the valley run noticeably hotter in summer than neighborhoods closer to the Bay. That shapes how systems wear. Air conditioners in warmer pockets work harder through long dry stretches, and furnaces and heat pumps often sit idle for months before the first cold, wet nights.

We keep that pattern in mind when we troubleshoot. A system that struggles on the first hot afternoon or the first chilly morning usually tells you something specific, and we look for it.

Straight answers about rules and incentives

Bay Area homeowners hear a lot about new appliance rules, and much of it is confusing. Here's what matters for repair decisions. The Bay Area Air District rules don't require you to replace working equipment. They apply only when an existing furnace or water heater fails or is replaced. Under Rule 9-4, natural gas furnaces made from 2029 on must meet a zero-NOx standard. In practice, that points homeowners toward heat pumps when they replace a furnace after that date.

The zero-NOx date for small water heaters under Rule 9-6 was set for 2027. The Air District Board is considering amendments in November 2026 that could delay it, so check the current rule before you plan a water heater replacement.

On incentives: the federal 25C tax credit covered qualifying heat pumps placed in service before December 31, 2025. It doesn't apply to new installations after that date. BayREN and local clean energy providers may offer heat pump and electrification incentives, but amounts and availability change by funding cycle. We confirm the current offer before we mention it in a quote.

• Working equipment doesn't have to be replaced because of the new rules
• Furnace rules change for units made from 2029
• Water heater timing may shift, so check the current rule
• Incentives change, so we verify them before quoting
