Why Is My Air Conditioner Not Working?

Why Is My Air Conditioner Not Working?

We know you want answers to two things right away: What’s wrong—and how much will it cost to fix it? While we can’t give you an exact cost until we inspect the system, here’s what’s usually to blame:

  • Low Refrigerant Levels: If your AC is blowing air but not cooling, low refrigerant is a likely cause. If there’s no major leak, a recharge is usually on the lower end of the cost scale—if we find a leak, we’ll walk you through your options.
  • Failed Capacitor or Thermostat: When your AC won’t turn on at all, it’s often a bad capacitor or thermostat—both are fairly quick and affordable to replace. If it’s just one of these common parts, you’re probably looking at one of the less expensive repair visits.
  • Clogged Air Filter or Dirty Coils: Dirty filters or coils reduce airflow and strain your system. These issues are some of the easiest (and cheapest) to fix.
  • Electrical or Control Board Issues: Electrical problems or a faulty control board can be trickier to pinpoint. Sometimes it’s a loose connection or a sensor; other times, it’s a full control board replacement—which is one of the more expensive AC repairs.

When we arrive, we’ll talk with you about what’s been going on, run a full diagnostic, and show you exactly what we find. We’ll explain the next steps and the air conditioner repair costs upfront. No surprise fees here—just fair pricing and high-quality work you can trust.

Complete AC Repairs That Solve the Problem, Not Just the Symptoms

Complete AC Repairs That Solve the Problem, Not Just the Symptoms

Your air conditioner doesn’t have to completely stop working to need attention. Running a system that’s clearly struggling—cycling too often, blowing warm air, or making unusual sounds—is one of the worst things you can do.

If something feels off, something is wrong. Whether it’s a burning smell, loud rattle, or your home just isn’t cooling like it should, Guthrie & Sons can help. Here are some of the most common air conditioning repairs in Clairemont and how we’ll handle them:

When your AC is running but the temperature never drops, it could be due to:

  • Low refrigerant
  • Dirty evaporator or condenser coils
  • A compressor that’s failing or overheating

In most cases, we can diagnose and repair it the same day with a refrigerant recharge or system cleaning. If the compressor is the problem, we’ll let you know—those situations may require a return visit or replacement, depending on the condition of the system.

If your AC won’t power up, the problem could be:

  • A tripped breaker or blown fuse
  • A failed capacitor or thermostat
  • An internal system lockout or wiring issue

These are issues we can usually fix during our first visit, often in under an hour. If we discover a larger electrical or control board issue, repairs might take longer or require a follow-up visit—but we’ll keep you informed every step of the way.

If your unit is buzzing, screeching, rattling, or banging, it’s trying to tell you something. Possible causes include:

  • Loose or broken parts
  • Worn-out motor bearings
  • Failing belts or misaligned fan blades

Most of these problems can be repaired quickly, often in a single visit. If the motor or another major component is failing, we’ll let you know whether it can be repaired or needs to be replaced to prevent further damage.

Leaks around your AC usually point to:

  • A clogged condensate drain line
  • A rusted or cracked drain pan
  • Frozen coils thawing and releasing water

These are usually easy to fix and can be taken care of during the same appointment. If there’s water damage inside the unit or ongoing drainage issues, we may need to schedule follow-up work or replace worn-out parts to fully resolve it.

Short cycling is rough on your system and utility bills. It’s often caused by:

  • A system that’s too big for your space
  • A malfunctioning thermostat or sensor
  • Blocked airflow or dirty components

If it’s related to a dirty filter or a sensor, we can usually fix it quickly. If it turns out your system is too large for the space, we’ll talk about what we can do now and what needs to be done later on when the unit is eventually replaced.

Repairing vs. Replacing Your Air Conditioner

We always aim to repair when it’s practical and the system still has good life left in it. But if your AC is over 12–15 years old, has outdated or discontinued parts, or has experienced a major component failure—like a bad compressor or control board—replacement may be the better long-term solution.

We’ll discuss the pros and cons of each option so you can decide what’s best for your home and budget. Guthrie & Sons services and installs all major brands of central air conditioners and heat pumps, so whatever route you choose, we’ve got you covered. But, we can’t do anything until you get your Clairemont AC repair on the books!

A Little Maintenance Now Will Save You a Lot Later

A Little Maintenance Now Will Save You a Lot Later

Most AC repairs we handle in Clairemont could’ve been avoided with regular maintenance. When coils get dirty, filters clog, or refrigerant runs low, your system has to work harder—and that usually means higher energy bills, more wear and tear, and surprise breakdowns during heatwaves.

That’s why air conditioning manufacturers all recommend annual air conditioning maintenance. It gives technicians like us a chance to catch small issues before they become expensive ones, clean things up, and make sure your system is ready for the higher temperatures.

But if you’d rather take this task off your plate completely, we offer our USA Membership Plan. It keeps your system on a regular maintenance schedule—automatically—and comes with extra perks like priority service, repair discounts, and a longer warranty.

What’s in the Guthrie & Sons USA Membership Plan?

Want a more reliable air conditioner, lower energy bills, and a system that lasts longer? Regular maintenance makes all the difference—and our USA Membership Plan makes it easy. You’ll get:

  • Service reminders
  • Priority scheduling
  • 15% off any repairs
  • Reduced service call fees
  • Extended 5-year parts and labor warranty
  • Seasonal heating and air conditioning tune-ups

You can read more about the plan on our website or call our office to learn more. Your technician can also share more firsthand info about how much it's helped our customers.

Frequently Asked Questions

It’s a quick rule of thumb: multiply the age of your AC by the cost of the repair. If that number is over $5,000, it may be smarter to replace the system rather than repair it. We’ll help you run the numbers and make a choice that fits your situation.

A failed capacitor is one of the most common issues we see. It’s a small electrical part that helps your AC start—when it goes, the system won’t turn on. Luckily, it’s usually fast and affordable to fix.

The compressor is typically the costliest component to replace. It’s what pumps refrigerant through the system, and when it fails—especially in older units—replacement often makes more sense than repair.

Most standard HVAC repairs aren’t covered by homeowners' insurance. But if your system was damaged by a covered event (like a fire, flood, or lightning), you may have some protection. It’s always best to check with your insurance provider.

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.
Neil Domingo

If you’re dealing with an AC issue, Mario is definitely one of the best! He quickly diagnosed the problem, worked efficiently, and provided a thorough solution. His expertise and professionalism were clear throughout the entire process. Highly recommend Mario for anyone looking to resolve their AC issues with a reliable and skilled technician.

Guthrie and Sons has provided great service. There are many HVAC companies in San Diego to choose from. They provided a very reasonable estimate for replacing our two AC systems. Once we said yes installation happened within days. It was a quality install. They answer the phone quickly when I've had questions. Happy to refer them to others.
