How Much Do Air Conditioner Repairs Cost?

Fast AC Repair Services That Fully Solve the Problem

Fast AC Repair Services That Fully Solve the Problem

Your air conditioner doesn’t have to completely quit for it to need service. If it’s cycling on and off too often, blowing warm air, or making new noises, running it anyway can cause more damage. If something doesn’t seem right, it usually isn’t. Guthrie & Sons can track it down and fix it. Here are some of the most common air conditioning repairs we see in Serra Mesa:

One of the most common calls we get is, “The system runs, but the house never cools down.” That can mean low refrigerant, dirty coils that can’t transfer heat, or a compressor that’s overheating. Low refrigerant or dirty coils are usually fixed the same day with a recharge or cleaning. If the compressor is failing, we’ll walk you through whether it’s worth repairing or if replacement makes more sense for the age of your system.

When the AC doesn’t power up at all, it can be as simple as a tripped breaker or as specific as a failed capacitor or thermostat. These parts are fairly quick to replace, and we keep them stocked on our trucks. Sometimes the issue is deeper—like a wiring problem or a control board failure—which can take longer. Either way, we’ll explain the problem clearly before moving forward.

ACs shouldn’t sound like a toolbox rattling around. If you hear buzzing, screeching, or banging, it’s often a loose part, worn-out motor bearings, or a belt that’s on its way out. These are repairs we can usually handle in one visit. If the noise is coming from a motor that’s burning out, we’ll help you decide whether replacing just the motor or planning for a bigger fix is the smarter call.

Seeing water around your AC is a sign that something’s wrong. A clogged condensate drain line, a cracked drain pan, or frozen coils thawing out are the usual suspects. Clearing a drain line or replacing a pan is straightforward, but if water has already backed up into the system, more cleanup may be needed. Taking care of leaks quickly is important—water damage can shorten the life of the unit and lead to more repairs for your flooring, furniture, and more.

Short cycling—when the AC keeps starting and stopping every few minutes—puts a ton of strain on the system and spikes your energy bills. It can be caused by a dirty air filter, a thermostat that’s not reading the temperature right, or a system that’s oversized for the space. If it’s a filter or sensor, that’s an easy fix. If the unit is too large for the home, we’ll talk about what can be done now to ease the wear and what your options are when it’s time for a replacement.

We know most people would rather repair than replace, and that’s always our first goal. But if your AC is 12–15 years old, uses parts that aren’t made anymore, or needs a major repair like a compressor or control board, replacement may be the smarter path forward. We’ll talk it through with you honestly, explain the pros and cons, and never push you into a decision. 

If an air conditioning replacement does make sense, we install all major brands of air conditioners and heat pumps—and we offer financing options to help make the cost more manageable. Whatever you decide, Guthrie & Sons will be there to make sure your home stays comfortable.

Keep Repairs Rare and Summers Comfortable With Our Maintenance Plan

Keep Repairs Rare and Summers Comfortable With Our Maintenance Plan

A lot of the AC repairs we’re called out for in Serra Mesa could have been prevented with simple, routine maintenance. When filters clog, coils collect dust, or refrigerant levels drop, your system has to work twice as hard to keep up. That drives up your energy bills, wears out parts faster, and often leads to breakdowns during the hottest days of the year.

That’s why every manufacturer recommends annual maintenance. A yearly tune-up each spring gives us the chance to clean the system, spot issues early, and make sure your air conditioner is ready for the increase in usage.

You can always schedule air conditioning maintenance with us, but if you’d rather not have to remember it yourself, our USA Membership Plan takes care of it for you. We’ll keep your system on a regular schedule and give you a whole bunch of exclusive benefits!

What You Get With the Guthrie & Sons USA Membership Plan

Want an air conditioner that’s more reliable, uses less energy, and lasts longer? Here’s what’s included:

  • Service reminders so you never miss a tune-up
  • Priority scheduling when you need us fast
  • 15% off any repairs
  • Reduced service call fees
  • Extended 5-year parts and labor warranty
  • Seasonal tune-ups for heating and cooling systems


You can sign up right through our office or ask your technician when they’re at your home. Many of our Serra Mesa customers have already signed up!

Frequently Asked Questions

It’s a simple way to decide if repair or replacement makes more sense. Multiply the age of your air conditioner by the estimated repair cost. If that number is over $5,000, replacement may be the smarter investment. We’ll walk you through the math and talk through your options so you can make the call with confidence.

One of the most common problems we see is a bad capacitor. This small electrical part gives your AC the boost it needs to start up. When it fails, the system won’t turn on at all. The good news is that capacitors are usually quick to replace and relatively inexpensive.

The compressor is typically the priciest component. It’s the part that circulates refrigerant through the system, and when it fails—especially in an older unit—it often makes more sense to consider replacement. We’ll always go through all of your options.

Most of the time, regular HVAC repairs aren’t included under homeowners’ insurance. But if your system is damaged by something like a fire, flood, or lightning strike, your policy may cover it. It’s always best to double-check with your insurance provider.

Kareen did an outstanding job with our HVAC system. From start to finish, he demonstrated professionalism, patience, and a strong commitment to getting the job done right. Even when faced with several unexpected challenges, he handled each one with skill and determination, never compromising on the quality of his work.

What really stood out was his problem-solving ability and willingness to go the extra mile to ensure everything was operating as it should. He communicated clearly throughout the process, kept us updated, and made sure we felt confident in the work being done.

It’s not often you come across someone who combines technical expertise with such a strong work ethic and positive attitude. We’re very grateful for his efforts and would highly recommend Kareen to anyone needing reliable HVAC service.

Professional from beginning to end

Vlad came out to provide an estimate and was able to size an HVAC system that worked well for my house.

They installed it quickly, without issue and helped me set up an app on my phone to control.

The system is working great to heat and cool my house and is whisper quiet.

Highly recommend going with Guthrie and Sons if you want a high quality experience for large and important purchases.

Our two old furnaces needed replacing and so we contacted Guthrie & Sons because of their good reputation. They sent Zach the next morning. He quickly verified that our two furnaces were beyond repair and Guthrie could supply and install suitable replacement funaces. He also suggested and explained alternative solutions, but we eventually decided to go ahead with furnace replacement. As soon as we notified Guthrie & Sons of our decision they arranged for Cristian and Pablo to come to our house the next day. They did a good job, explained clearly how to operate the new furnaces and thermostats, and were respectful of our house.

Daniel was quick and professional. Fixed our AC problem in an hour and the price was very transparent and beyond fair. Didn’t push the subscription maintenance service, simply said it would be a good idea due to the age of our unit. Highly recommend!

We had to replace a thermostat that had gone bad. In the old days, I could do it myself. Now, though, the programming of the thing requires technical knowledge that I don’t have. The Guthrie guy that did the job was courteous, professional, and as fast as anyone could be. This has been our experience with Guthrie & Sons for every repair, retrofitting, and equipment replacement that they’ve done for us over quite a number of years now.

Carson Snyder and co-worker (Pablo?) did a great job on the installation of the mini-split cassette. They're hard working, they clearly knew what they were doing, polite, cleaned up afterwards, true professionals. I'd gladly recommend these two gentlemen. However, the Company was not good at keeping me informed although I mentioned to the salesman up front that I was information driven. They were short on details and communicated seldom. Anthony did tell me about the government program available that reduced my cost. I wouldn't have known about it if he didn't mention it. The City did approve their work and signed off on the permit which is an indication of the job done right. I think the Company can improve their customer service

Very pleased with the service we received from Guthrie & Sons! Our AC system needed to be replaced after a huge leak. The tech that came out for diagnosis, Mario, took the time to explain the issue to us, as well as our options for repair. They came out on a Saturday to diagnose and it was fixed the following Tuesday. Matthew was the worker that completed the repair and he did an excellent job. Pricing was reasonable. Much more reasonable than the first company we had come out to take a look. We upgraded our system and our SDG&E bill has already gone down. Highly recommend!

Very knowledgeable and professional. Quoted product was high quality and fair pricing. I highly recommend We ended up not going with them only due to the fact we were also getting Solar and ended up going with one company for our project but I would definitely do business with this company in the future if we need it!

We had Guthrie and Sons replace our 50 year old house heater with a heat pump. We are very satisfied with the installation performed by Matthew and Andriy. We were impressed with the detail of their work. They paid particular attention to the required sealing and insulating of the system. Even the HERS testing inspector was impressed with their work. We were also impressed by their professionalism and honesty. They gave us an unexpected partial refund off our signed contract.

We have been using Guthrie & Sons for 3 years and I really can’t say enough good things about them. Our technician Mario was incredibly helpful with our most recent AC issue. He spotted the problem quickly and was very knowledgeable when explaining what was happening. I appreciate their honest and fair pricing and would recommend to family and friends. Glad to have an honest company especially with all the price gauging company’s out these days.

We were incredibly impressed with the prompt and professional service! We called on a Saturday morning, and within just a few hours, a technician was at our home. With the recent heat, getting our AC back up and running was a top priority—and they delivered! Mario clearly explained our options and provided a hassle-free solution that was both quick and effective. The repair was completed shortly after we gave the go-ahead. We’ll absolutely be using them again for any future HVAC needs. Highly recommend this company for their affordability, efficiency, and friendly service—we’re already telling our family and friends! Thanks again Guthrie & Sons!

We were very happy from start to finish. Vlad did a great job in helping us decide what would be best for our house and our needs and the installation crew were the very best. Thank you Guthrie and Sons for a job well done.

Last summer, I used Guthrie and Sons to replace my heating system with a new one and added an air conditioning unit. We also added two different zones in the house to be able to turn the system on independently from one zone to another. From the first contact to the six month maintenance visits, everything has gone smoothly. There were a couple of hiccups, but the company is very responsive and I have never had an issue with them not promptly responding and taking action to figure out and solve any problem. I highly recommend this company.

Guthrie & Son's did an amazing job on our new AC units. From sales through install they were all knowledgeable and helpful. They were very quick to get us all setup and when our home posed some unexpected issues they were able to pivot quickly and resolve them. I'd highly recommend them!

Had use Guthrie in the past for HVAC service, this time had them install a solar attic fan and additional vent. The service, as it had been the first time, was professional, polite, and on schedule. Pricing was fair (and consider that they offered a repeat customer discount without having to be asked). Would be happy to use them again when the need arises.
I offer 4 stars because I'm not a grade inflation sort. Three is sufficient, four is better than average. Five is reserved for knock my socks off amazing in ways I didn't expect - doesn't happen very often.

We had central heat and air put in two a year and a half ago. We've need to make a few adjustments to airflow to rooms since then. Each time, they are onsite withing 1-2 days and have resolved the issue each time. Their team is professional and incredibly friendly and knowledgeable. Very happy we went to Guthrie & Sons.

Mario was knowledgeable and courteous. He made sure our system would be sized right and that our existing ductwork was able to support the new system. The install team were prompt and efficient. They installed drop cloths and cleaned up inside and out after the job. So far I’ve been very happy with the work Guthrie and Sons have done for us.

Great local family business. And you actually get a live person when you call... And the technician was great and they come out quickly. No up selling too. He gave me two different price options on fixing my problem... band aid cheaper way or replacement. Great service.

Jonathan recently inspected the HVAC systems at both my front and guest houses, and I couldn’t be more impressed with his service. He was thorough in his assessment, clearly identifying areas of concern and explaining the recommended repairs in a way that was easy to understand. What stood out most was his honesty and patience—he took the time to answer all my questions without rushing, and I genuinely felt he had my best interest in mind. If you're looking for someone who is knowledgeable, professional, and respectful of your time and property, I highly recommend asking for Jonathan.
