Heat Pump Repair in San Jose, CA
Same-day heat pump repair for Bay Area homes and businesses. Free diagnostics – no charge to assess the problem. Licensed, EPA-certified team, available 24/7. If we can’t fix it on the first visit, you don’t pay a trip fee.
The Most Efficient Way to Heat and Cool Your Bay Area Home
When your heat pump stops working, the problem is rarely obvious. It may keep running but fail to heat, freeze up overnight, or short-cycle without reaching the set temperature.
Ozone Service provides same-day heat pump repair across San Jose and the entire Bay Area.
We identify the exact issue and give you a clear written quote before any work begins. No charge. No obligation.
We hold both HVAC and electrical licenses. Since most heat pump failures involve electrical problems such as a bad capacitor, failed contactor, tripped breaker, or wiring issues, we handle everything under one contract and one warranty. No double visits, no separate invoices, and no confusion
What Every Repair Visit Includes
Every service call starts with a complete diagnostic – not a cursory look. Here’s what’s included in every visit, at no charge before any repair decision is made:
Full System Diagnostic
We test refrigerant pressure, electrical components, airflow, thermostat signal, and defrost cycle operation. We don’t assume – we measure. The diagnostic takes 45–90 minutes and covers every subsystem that could be causing the fault.
Written Repair Scope & Price
Before we touch anything, you get a written quote. What the problem is, what the fix involves, what it costs, and how long it takes. No surprises when the invoice arrives.
Same-Day Repair When Parts Are Available
We stock the most common failure parts on our service vehicles – capacitors, contactors, reversing valves, fan motors, and control boards. Most straightforward repairs are completed on the same visit as the diagnostic.
Electrical Fault Coverage
If the repair requires electrical work – panel circuit, disconnect box, low-voltage wiring, or thermostat wiring – our licensed electricians handle it in-house. No second contractor, no scheduling gap, no split accountability.
Post-Repair System Verification
After the repair, we run the system through a full heating and cooling cycle, verify refrigerant charge, check airflow, and confirm the fix held before we leave. We don’t call a job done until the system performs correctly.
Warranty on All Repairs
Parts and labor are covered. If the same issue recurs within the warranty period, we return and fix it at no charge. Ask about specific warranty terms during the service call.

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.
From First Call to Completed Repair
Step 1
Call or Book Online
Tell us what’s happening with your system – the symptom, when it started, and whether it’s heating, cooling, or both that’s affected. We’ll dispatch a licensed technician for same-day or next-available service. 24/7 availability for emergency situations.
Step 2
On-Site Diagnostic
The technician runs a complete diagnostic: refrigerant pressures, electrical measurements, airflow checks, thermostat signal, and defrost cycle operation. This takes 45–90 minutes and is included at no charge. You’ll know exactly what’s wrong before we quote anything.
Step 3
Written Quote
We present a written repair scope: what the fault is, what the repair involves, which parts are needed, and the total cost. You review it, ask questions, and decide. No pressure, no time limit. If you’re not ready to proceed, there’s no charge for the diagnostic.
Step 4
Repair
Most common failures are resolved on the same visit – we stock frequently needed parts in our service vehicles. If a part needs to be ordered, we give you a specific timeline. We don’t start work until you’ve approved the quote.
Step 5
Post-Repair Verification
After the repair, we run the system through both operating modes, verify refrigerant charge and airflow, and confirm the fix held. We’ll walk you through what was done, show you any replaced components, and review maintenance basics that can prevent recurrence.
Why Bay Area Homeowners Call Us for Heat Pump Repair
HVAC and Electrical Under One Roof
Most heat pump failures have an electrical component. A failed capacitor. A tripped breaker feeding the outdoor unit. A low-voltage wiring fault between the thermostat and air handler. When your HVAC tech hits an electrical problem, they either guess at it or call you to find an electrician. We don’t. Our technicians hold both HVAC and electrical licenses - one visit, one scope, one warranty.
Free Diagnostics, Written Before Any Work Starts
We don’t charge a trip fee to look at the system. We don’t present a verbal estimate. You receive a written diagnosis and a written price before any work begins. The number you approve is the number you pay.
Same-Day Service, 24/7 Availability
Heat pump failures don’t happen at convenient times. We provide same-day service across San Jose and the Bay Area, with 24/7 availability for emergency situations. If you call before noon, we’ll be there the same day in most cases.
All Major Brands Serviced
We work on all nine brands in our portfolio - Mitsubishi, Daikin, Carrier, Trane, Lennox, Goodman, Rheem, and others. Brand-specific diagnostic tools, not generic guesswork. If the part isn’t on our truck, we source it - we don’t substitute an incompatible component to close the job fast.
Warranty on Every Repair
Parts and labor are covered in writing. If the same fault returns within the warranty period, we come back and fix it at no charge. No diagnostic fee, no labor charge.
What You Get
Common AC Repairs We Handle in San Jose
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

Heat Pump Repair - Answered Honestly
My heat pump is running but not heating. What’s wrong?
The most common cause is a reversing valve stuck in cooling mode or a refrigerant charge that’s dropped low enough to prevent effective heat transfer. Less commonly, it’s a defrost control issue preventing the outdoor unit from operating correctly in colder weather. We diagnose all three during the standard service call.
How much does heat pump repair cost in the Bay Area?
The cost of a heat pump repair depends on what’s broken. We don’t charge for the diagnostic visit – you receive a written quote before any work begins. The ranges below reflect typical repair costs in the Bay Area market.
Is the diagnostic visit free?
Yes. We visit, run a full system diagnostic, and give you a written repair scope and price. There’s no charge for the diagnostic. If you decide not to proceed, you don’t pay for the visit.
Should I repair or replace my heat pump?
The decision depends on system age, fault type, and repair cost relative to replacement. If the system is under 8 years old and the fault is a single failed component, repair almost always makes more sense. If the compressor has failed on a system over 10 years old, replacement is usually the better financial decision. We’ll give you both numbers so you can decide without pressure.
Can you service my brand of heat pump?
We service all nine brands in our portfolio: Mitsubishi, Daikin, Carrier, Trane, Lennox, Goodman, Rheem, and others. We carry brand-specific diagnostic tools and order OEM parts when available.
Do you offer 24/7 emergency repair?
Yes. For situations where the system has failed completely – no heating in winter, no cooling during a heat event – we provide emergency dispatch outside regular hours. Call (669) 629-4440 any time.
My heat pump is making a loud noise. Is it safe to keep running?
It depends on the noise. A rattling that started recently is often a loose part or debris – low urgency, but worth checking. Grinding or metal-on-metal sounds usually mean a bearing failure in the fan motor or, in serious cases, a compressor problem – turn the system off and call us. Running a system with a failing compressor can turn a repair into a full replacement.
What warranty do you provide on repairs?
Parts and labor are covered in writing. If the same fault recurs within the warranty period, we return and fix it at no charge – no diagnostic fee, no labor charge. Ask about specific terms during the service call.
