If your air conditioner is blowing warm air or completely dead, you don’t have to hunt through our site for answers. Here is exactly how we resolve your problem today:
Same-Day Service: We prioritize non-cooling homes across Santa Clara and San Mateo counties to ensure your system is up and running today
21% Off Labor + Free Diagnostic: You get a $0 diagnostic fee with your repair and a 21% labor discount applied automatically to your invoice.
Upfront Flat-Rate Pricing: Our technician will find the root cause and give you a clear, fixed price before any work begins. No hidden fees, no surprise charges.
Fixed in a Single Visit: Our trucks arrive stocked with the parts that fail most often – capacitors, fan motors, switches, and refrigerant – so most repairs are done on the spot, not scheduled for a second trip.
Written Warranty Protection: Every urgent repair is backed by a solid warranty on both parts and labor, giving you total peace of mind.

What a Heat Pump Actually Costs After Incentives
The gross cost of a heat pump installation is only part of the picture. Bay Area homeowners have access to three stacking incentive programs that significantly reduce out-of-pocket cost.
We identify which programs apply to your project, ensure the installation meets all rebate program requirements, and handle the documentation. Most contractors don’t touch the paperwork – we do.
Sample Сalculation
San Jose homeowner, heat pump installation, standard income:
SVCE
$2,500
CA Energy-Smart Homes
$5,750
Net savings
$8,250
Rebate availability changes quickly and is often first-come, first-served or waitlisted. We calculate your exact eligibility and current stacking options as part of the free estimate – no guesswork, no surprises.
This Service May Cost Less Than You Think
Bay Area utility programs and state energy incentives may offset a significant portion of your cost. We check what applies to your home and handle all the paperwork – as part of your free estimate, at no charge.
Why Homeowners in Santa Clara & San Mateo Counties Trust Ozone Service?
Diagnosis First. Price Second. Repair Third.
We don't recommend repairs before we've found the actual cause. Every service call starts with a full system diagnostic - airflow, refrigerant pressure, electrical components, and thermostat response. You hear the diagnosis before you hear a price. And you hear the price before we start any work.
HVAC and Electrical Under One License
AC failures frequently involve electrical components - contactors, wiring, disconnect boxes, and panel capacity. When your HVAC tech can't touch the electrical side, you're scheduling two appointments and splitting the warranty. We carry both licenses. One technician, one invoice, one warranty.
No Subcontractors - Ever
Every technician is a direct Ozone employee. Not a sub, not a seasonal hire. Background-checked, EPA 608 certified, and trained to work on the brands and systems common in Bay Area homes.
What You Get
Refrigerant pressure check
Low refrigerant doesn’t just reduce cooling – it strains the compressor until it fails. We locate the leak, repair it, and recharge the system to manufacturer spec. Adding refrigerant without fixing the source is a temporary patch that accelerates damage. Our EPA 608-certified technicians handle all refrigerant work in compliance with California regulations.
Evaporator and condenser coil cleaning
Dirty coils reduce efficiency by up to 30% and cause the system to run longer and hotter
Electrical components (capacitors, contactors, wiring)
These degrade before they fail so catching them early costs a fraction of emergency repai
Condensate drain flush
Prevents water damage and mold buildup common in Bay Area summer humidity
Airflow and filter assessment
Restricted airflow is the single most common cause of early system failure
Thermostat calibration check
A 2°F error makes the system run longer than it needs to, wasting energy and causing wear.
Full system performance report
Written findings with recommendations. You keep the report with no commitment required

AC Repair Questions - Answered Honestly
How much does AC repair cost?
The cost depends entirely on what’s wrong. Start-group replacement, including capacitor and contactor – starts at $195. Refrigerant charge (R410, R454, R32) – $300. We give you the exact price after the diagnostic, before starting any work. No trip fees ever.
What warranty do you provide on AC repairs?
Every repair comes with a written warranty on parts and labor. If the same issue returns within the warranty period, we fix it at no charge – no diagnostic fee, no trip charge. Up to 1-year labor warranty on every repair work and up to 5-year parts warranty depending on the manufacturer.
My AC is running but not cooling. Should I turn it off?
If you see ice forming on the indoor unit or refrigerant lines, yes, turn it off and call us. Running with frozen coils forces the compressor to work without proper refrigerant flow and causes compressor damage. If there’s no ice visible, you can leave it running while waiting for the technician, but don’t lower the thermostat to force more cooling – it won’t help and adds wear.
How long does AC repair typically take?
Most standard repairs – capacitor, contactor, thermostat, and condensate drain – are completed in 1–2 hours during the diagnostic visit. More complex repairs involving refrigerant work or electrical components may require a return visit if specific parts need to be ordered. We give you a timeline estimate before starting.
Should I Repair or Replace my AC System?
There’s no universal answer, but there’s a straightforward framework for making the decision. We give you both numbers during the diagnostic so you can decide without sales pressure.
