Signs You Need a Heat Pump Repair Company

A lot of homeowners move into homes with heat pump systems and aren’t sure how they’re supposed to behave. What’s normal? What’s a red flag? If you’re in that boat and looking for answers, here’s when to call for heat pump repair service:

Not Switching Between Heating and Cooling: Your heat pump should smoothly switch modes based on your thermostat setting. If it won’t change, gets stuck, or takes a long time to respond, there’s an issue.

Running Nonstop: It’s normal for the system to run more when it’s really hot or cold, but it should cycle off now and then.
Short Cycling: Your system should run for 10–20 minutes per cycle. If it kicks on and off every few minutes, that’s not normal and can wear out the system.
Frost or Ice on the Outdoor Unit: A thin layer of frost is okay and should melt on its own. Heavy ice or freezing in mild weather means it’s time for service.
Loud or Unusual Noises: A gentle hum is normal, but banging, clicking, humming, or screeching aren’t part of normal operation.
Leaking Refrigerant: Your heat pump should never lose refrigerant. If it’s leaking, you need heat pump service right away.
Big Spike in Utility Bills: A small jump between seasons is expected, but if your energy use suddenly shoots up, the system isn’t running efficiently.

Heat Pump Troubleshooting Tips

We don’t recommend trying to fix your heat pump yourself, no matter how easy that online tutorial makes it look. But we’re all for a little light troubleshooting before you call, especially if it saves you time and money.

Check the Thermostat Settings: Make sure it’s set to “heat” or “cool” (not just “on”) and that the temperature is set a few degrees above or below the current room temp.
Inspect the Air Filter: A clogged or dirty filter can restrict airflow and make the system work harder—or stop working altogether.
Flip the Breaker: Check your electrical panel to make sure the heat pump hasn’t tripped the breaker, especially if it shut down unexpectedly.

If none of that fixes things, you need our heat pump contractors to come out. Trying to fix electrical or refrigerant issues on your own can lead to expensive damage, void your warranty, or even create a safety hazard.

Restore Your Home’s Heating and Cooling With Our Heat Pump Repair Service

A heat pump keeps your home comfortable by moving heat—pulling it out when it’s hot, bringing it in when it’s cold. Wear and tear is normal, and over time, things can start to slip—airflow gets weaker, parts wear out, or it just doesn’t switch modes the way it should.

At Guthrie & Sons, we handle these common heat pump repairs and more. Whether it’s a simple fix or a full system issue, we have the heat pump solutions that you need.

If your system is set to cool but it’s pushing out warm air, something isn’t switching properly. This often points to a problem with the reversing valve, thermostat, or control board. We’ll test the system, confirm the source, and replace the part if needed.

Heat pumps should cycle on and off depending on indoor temperatures—not run all day. If yours is constantly running, it could be low on refrigerant, misreading the thermostat, or struggling with airflow. We’ll check for blockages, test refrigerant pressure, and make adjustments or repairs as needed. When we’re done, your system will work more efficiently and your wallet will thank you.

Banging, buzzing, or screeching coming from your heat pump? That’s not just annoying—it’s a sign something’s wrong. It might be a failing motor, loose components, or electrical arcing. Our heat pump experts will find the cause fast and get things tightened up, replaced, or rewired as needed. We’ll leave your system running smoothly—and quietly.

A little frost in winter can be normal, but thick ice or freezing during mild temps isn’t. Your system might have a blocked airflow, sensor issue, or be low on refrigerant. We’ll safely defrost the unit, fix the underlying issue, and restore normal function.

When your heat pump doesn’t turn on at all, the problem could be electrical, mechanical, or thermostat-related. We’ll start with a full diagnostic—checking the thermostat, breakers, capacitor, and more. Once we find the issue, we’ll walk you through your options clearly before making any heat pump repairs.

Short cycling wears down your system and makes your home less comfortable. This could be caused by dirty filters, overheating, or a failing control board. We’ll pinpoint the cause, make the fix, and prevent unnecessary wear on your heat pump system. Once resolved, your heat pump will run in steady, normal cycles again.

If your heat pump is leaking, it’s likely one of two issues. The first is excess condensation that isn’t draining properly, usually caused by a clogged drain line, dirty coil, or frozen coil due to low refrigerant. When that ice melts, the water can overflow. The second—and more serious—possibility is a refrigerant leak. Refrigerant leaks can cause poor performance, higher energy use, and ice buildup. If we suspect a leak, we’ll run a full diagnostic, find the source, and repair it safely.

At Guthrie & Sons, we always try to fix the problem first. We’ll inspect your HVAC system and recommend the most practical solution. But sometimes, repairing a heat pump just doesn’t make sense—especially if it’s more than 10–12 years old, the compressor has failed, or the heat pump repair cost is close to what you’d spend on a brand-new system.

Want to Avoid More Heat Pump Repairs and Save Money? Schedule Maintenance With Us

We get a lot of service calls when the weather shifts—heat pumps that won’t cool when it gets hot, or suddenly stop working when it turns cold. And most of the time, it comes down to missed maintenance and repair services. Your heat pump only needs service twice a year, and those checkups go a long way.

During your heat pump maintenance appointment, we can catch loose parts, airflow issues, or signs of wear before they turn into full-blown breakdowns. Regular maintenance also helps your system switch modes properly and run more efficiently, so you’re not stuck sweating in July or bundled up inside in January.

Protect Your Comfort With a Maintenance Plan That’s Easy to Keep Up

Life’s busy—you’ve got enough to remember without wondering when your heat pump needs a tune-up. That’s why we created our USA Membership Plan. It’s designed to keep your system on schedule automatically, with service in spring and fall to prep for the seasons ahead.

No phone tag. No scrambling when something breaks. You get reminders, priority scheduling, discounted rates, and maintenance that makes a huge difference in how your home feels. Just sign up once, and we’ll take it from there.

Frequently Asked Questions

Compressor replacement is usually the most expensive type of HVAC heat pump repair. It’s a major component, and in older systems, the cost can rival a heat pump replacement.

The most affordable fixes are usually related to thermostats, clogged filters, or a tripped breaker. These minor issues often cost less and can be caught early. We’ll give you a clear diagnosis so you know exactly what’s needed and what’s not.

It depends on what’s wrong, but we always start with a full heat pump repair estimate. Costs vary based on the part, labor, and whether it’s a quick fix or something deeper. We’ll explain everything clearly so there are no surprises with your HVAC repair bill.

Yes—older systems are more likely to need harder-to-find parts or multiple repairs. In some cases, putting money into a failing system costs more than it’s worth. We’ll help you compare your repair costs to a replacement and make the best call.

We recently had our A/C replaced by Guthrie & Sons, and I cannot recommend them highly enough. After getting five different bids, Guthrie & Sons stood out immediately—not just on price, but on expertise and professionalism. They even brought their engineers out to ensure the work could be done the right way, which gave us tremendous peace of mind.

From start to finish, their team was outstanding. They worked incredibly hard, treated our home with respect, and left everything spotless—truly the cleanest job site I’ve ever seen after a major project. The installation itself was seamless, and the quality of their work shows in every detail.

If you’re looking for a company that combines deep knowledge, excellent craftsmanship, and genuine care for their customers, Guthrie & Sons is it. Absolutely five stars across the board!

We had a wonderful experience with Guthrie and Sons. Anthony was our estimator and he did a very thorough job of explaining all of our options! Matthew, Bryan, and Isaiah were our installers and they were very efficient, capable, and personable. Our home did not have an existing HVAC system so they had to build the whole thing in an older house that had undergone several additions. We were up and running in just three days. They left the worksite clean at the end of each day. We highly recommend Guthrie and Sons!

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.

Carrie Reese

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!

Kenneth Adelson

16:04 07 Jul 25

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.

Bennie Beans

15:41 12 Jun 25

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.
