How Much Will My HVAC Repair Cost?
We get it; this is the first question you want answered. And while pricing can vary, we’ll always start by coming out, inspecting your system, and talking through what’s going on. Then we’ll give you clear options, get your go-ahead, and get the work done.
Here’s what to keep in mind about your HVAC repair costs and the work involved:
- Smaller HVAC repairs, like replacing a bad thermostat, clearing a clogged drain line, or changing a worn capacitor, usually cost less.
- Larger problems, such as a failed blower motor, damaged heat exchanger, or refrigerant leak, can be more expensive. If the system is older, parts may also be harder to find and cost more.
Oftentimes, problems can be solved with affordable HVAC repairs. If the damage is severe and an HVAC replacement deserves to be part of the conversation, we'll explain why and walk you through your options. With our San Diego HVAC repair service, you can expect us to do what's right for you and your home.

If you have an urgent concern, please contact us for an emergency HVAC repair. You can read more about our HVAC repair services below.
Air Conditioning Repair
Between the marine layer mornings and the warm inland afternoons, San Diego AC systems are constantly adjusting, which can strain components and shorten their lifespan. Homes near the coast also deal with salt air that corrodes coils and electrical connections faster than you'd expect. We handle AC repair for all of it, from worn-out parts to corrosion damage, so your system runs the way it should.
Heat Pump Repair
San Diego's mild winters make heat pumps a popular choice, but our humid coastal air can still cause ice buildup on outdoor units during those cooler nights. When that happens, you might notice weak heating, strange noises, or a system that won't defrost properly. Whether you need heat pump heating repair or heat pump air conditioning repair, our techs handle both sides of the system and will get things back to normal with the right heat pump repair.
Furnace Repair
San Diego's short heating season means many furnaces sit unused for months, which can lead to dust-clogged components and igniter issues once you finally turn the system back on. Whether you need a furnace repair on the first cold day or later in winter, we fix heaters that won't turn on, blow cold air, or shut off unexpectedly. Our team will handle your heating repair fast and have your home warm again in no time.
Indoor Air Quality System Repair
We don't just fix your heating and cooling; we also repair the systems tied to your HVAC, including thermostats, dehumidifiers, and air purifiers. If your thermostat is showing incorrect readings or not communicating with your system, our thermostat repair will get temperatures accurate again. San Diego's coastal humidity can also overwork dehumidifiers, and dusty inland conditions strain air purifiers, so we offer both dehumidifier repair and air purifier repair to keep your indoor air clean and balanced.
We know a broken AC or furnace often comes with a bigger worry: repair or replace? If your unit is under 10 years old and the issue is minor, an HVAC repair is usually the right call. But if it's older, breaks down often, or keeps getting pricier to fix, it may be time to consider an HVAC replacement instead. We won't know until we take a look, but we're here to help either way with HVAC financing, a free online quoting tool, special offers, and help finding available rebates and tax incentives. Choose the HVAC service San Diego homeowners recommend to their neighbors for honest work and honest people.
Make Fewer Repair Calls With More Regular Maintenance
It may not always seem like it, but we ask a lot from our HVAC systems. Our air also has dust, salt, and moisture in it, and that stuff gets into your system. Coils get dirty. Filters clog. Parts overheat. When you skip maintenance, those things can pile up and turn into expensive HVAC repairs.
No matter what kind of system you have, annual HVAC maintenance makes a big difference. At Guthrie & Sons, we offer seasonal tune-ups for everything: ACs, heat pumps, furnaces, and ductless mini-splits.
Want to make it even more worth your time and money? Our USA Membership Plan gives you priority service, repair discounts, reduced service fees, and extended warranty options. We have plans to fit your needs and your system.
Frequently Asked Questions
Does the warranty cover HVAC repairs in San Diego, and how can I verify this?
Most manufacturer warranties cover parts for a set number of years, but coverage often depends on regular maintenance records and proper installation. To verify what's covered, check your original paperwork or give us a call, and we'll help you look into it. Our HVAC repairman can also confirm whether your repair qualifies before any work begins, so there are no surprises.
How much will my HVAC repair cost?
Repair costs vary depending on the issue, your system's age, and the parts needed, so it's hard to give an exact number without an inspection. Minor fixes tend to be more affordable, while issues involving major components like compressors or coils cost more. We'll always give you an upfront quote before starting any work, so you know what to expect during your San Diego, CA, HVAC repair.
Can I handle any DIY heating and cooling repairs?
Simple tasks like changing filters, clearing debris from outdoor units, or resetting a tripped breaker are safe for most homeowners to handle. Anything involving refrigerant, electrical wiring, or internal components should be left to a professional, both for safety and to avoid voiding your warranty. When in doubt, the HVAC repair San Diego homeowners trust is just a quick phone call away.
How long can I expect my HVAC repair service to take?
Many San Diego HVAC repairs, like fixing a capacitor or clearing a clogged drain line, can be completed in under an hour. More involved repairs, such as those requiring special-order parts, may take a day or two depending on availability. We’ll keep you updated every step of the way so you're never left guessing. We’re the HVAC company San Diego counts on for fast service and fair prices.
What simple maintenance steps can I take to avoid costly HVAC repairs in San Diego?
Changing your air filter every 1-3 months is one of the easiest ways to keep your system running efficiently and avoid unnecessary strain. You should also keep the area around your outdoor unit clear of debris, leaves, and dust, since San Diego's dry conditions can build up quickly. Scheduling an annual tune-up with our HVAC repair service catches small issues before they turn into bigger, more expensive problems.

Real Reviews From Real Customers
We do things differently, and our customers appreciate it. See what some of our thousands of satisfied customers have to say about working with us.





As far as price goes, I paid a higher flat fee 12 years ago from one of the larger local companies. I'm very impressed with pricing and quality of work.
I highly recommend Guthrie & Sons and Rob.


Christian and his crew did a great job on the install everything was smooth from start to finish.
I would definitely recommend this company here in Murrieta.




Please congratulate them for a job well done!





We worked with Vlad T., who had previously been out to our home and saved us tens of thousands of dollars by getting our existing AC unit up and running when other companies were pushing for a full replacement. That experience alone earned our trust.
Now that we’re finally ready to purchase new units, there was no question that Guthrie & Sons was the only company we would consider, and Vlad was the obvious choice. He was extremely professional, punctual, and exceptionally knowledgeable, taking the time to explain options clearly and thoroughly. His expertise and honesty made the entire process straightforward and stress-free.
If you’re looking for an HVAC company you can truly trust—one that values integrity, quality workmanship, and customer service—I cannot recommend Guthrie & Sons and Vlad T. highly enough. This is how service should be done.




I only wish the annual service was cheaper 🙂
