Benefits of Routine Heat Pump Maintenance

Benefits of Routine Heat Pump Maintenance

No one wants to be surprised by a broken heat pump on a hot afternoon or a cold morning. And no one enjoys calling for emergency repairs. The best way to avoid those situations? Stay on top of maintenance. A well-maintained heat pump runs better, lasts longer, and saves you money on energy and repairs. It’s not just about keeping your system clean—it’s about keeping your home running smoothly. Here’s why scheduling routine heat pump maintenance is worth it:

  • Extended Lifespan: Most heat pumps last around 10–15 years, but with consistent maintenance, many systems can keep going strong for 18–20 years or more.
  • Fewer Heat Pump Repairs: The average homeowner can expect to spend hundreds to thousands of dollars on HVAC repairs over a system’s life, but many of those repairs are preventable with professional heat pump maintenance.
  • Enhanced Efficiency: Heat pumps that haven’t been serviced in a while often lose 10–25% of their efficiency just from dust buildup, clogged filters, or low refrigerant.
  • Protected Warranty: Nearly every manufacturer requires proof of annual professional maintenance to keep your warranty intact. If you skip a tune-up and something breaks, you could be left covering the full repair or replacement cost.
  • Better Air Quality: A neglected heat pump can collect mold, mildew, pet hair, and dust that gets pushed back into your home every time it runs.

Don’t wait for your heat pump to call it quits—stay ahead with our heat pump check-up services. One quick visit can boost efficiency, cut energy costs, and more!

How Often Should I Have My Heat Pump Serviced?

Because your heat pump works double duty, it needs more frequent attention than a typical AC or furnace. At Guthrie & Sons, we recommend heat pump tune-ups twice a year: once in the spring before the heat hits and again in the fall before cooler weather rolls in.

Signs It’s Time to Schedule a Heat Pump Tune-Up Today

If it’s been more than six months since your last heat pump check-up, or you’re noticing things like:

  • Longer run times to heat or cool your home
  • Uneven temperatures from room to room
  • Higher energy bills without a clear reason
  • Weird noises like rattling, buzzing, or humming

…it’s time to book a heat pump maintenance appointment. Our HVAC technicians know these systems inside and out and offer heat pump tune-up services for air source heat pumps, absorption heat pumps, and ductless systems. We offer same-day servicing when possible and will always tell you what’s really going on without trying to sell you something you don’t need.

What to Expect During a Heat Pump Tune-Up

What to Expect During a Heat Pump Tune-Up

When you schedule heat pump maintenance with Guthrie & Sons, we don’t just breeze in, wipe down a few parts, and leave you with a bill. We take a detailed, hands-on approach to make sure your system is clean, efficient, and operating safely—because that’s what it takes to keep your home comfortable year-round. Each visit includes full heat pump inspection services, detailed heat pump troubleshooting, and minor heat pump repairs that make a difference in how your home feels. Whether your system has been acting up or it’s just overdue for service, we’ll get to the bottom of it and give you the expert heat pump services your home deserves.

Here’s what our technicians will do during your heat pump service in the San Diego area:

We begin by testing how your system starts and stops. It should kick on quickly, shut off cleanly, and switch between heating and air conditioning without delay. If it hesitates, we’ll figure out why.

Dirty coils are one of the biggest reasons heat pumps lose efficiency. We clean off grime, dust, and debris to help your system move heat more effectively—so it cools and heats your home faster and with less energy.

Loose wires can cause power loss, system failure, or even short circuits. We check every connection and tighten anything that’s out of place. It’s one of those small things that can prevent a big problem.

If your thermostat isn’t calibrated right, your system can run too long or not long enough. We make sure it’s accurately reading the temperature and communicating properly with your heat pump.

We check motors, fans, and other moving components for friction and wear. A little lubrication goes a long way in preventing breakdowns and keeping everything running quietly and smoothly.

Low refrigerant can lead to poor performance and compressor damage. We measure levels and pressures, look for signs of a leak, and make sure everything’s within the proper range.

A clogged drain line can back up water into your home or shut down the system completely. We clear out any blockages to keep moisture flowing out where it’s supposed to go.

We check your air filter and overall airflow to make sure your system isn’t being choked by dust or debris. If the filter’s dirty, we’ll replace it—or let you know what to grab if it’s a custom size.

Before we leave, we run your system in both heating and cooling modes to make sure it’s responding properly. If anything feels off, we catch it now, not when it’s 95 degrees or 40 and raining.

Need Other Heat Pump Support Services? We Repair and Replace, Too

During your heat pump tune-up in San Diego, if we find something small—like a weak capacitor or a loose fan belt—we’ll usually take care of it on the spot. But if your unit needs more involved heat pump repairs, we’ll walk you through what’s happening, what parts are needed, and what kind of work is involved.

And if it turns out your system is on its last legs, we’ll be honest with you. We’re not in the business of keeping a failing system alive just to patch it up again later. If it’s time for a heat pump replacement, we’ll help you find the right fit and walk you through our financing options, free online quoting tool, and help you take advantage of available rebates or tax incentives. We’ll help you save money now and set you up with a better system for the future.

Frequently Asked Questions

We recommend annual heat pump services: once in the spring and once in the fall. Since your system works year-round, this timing helps it run better in both heating and cooling seasons.

Yes! You can replace the air filter regularly, clear leaves or debris from around the outdoor unit, and keep vents unobstructed. Just leave the internal components and electrical work to trained HVAC heat pump maintenance technicians.

Our coastal air can cause salt buildup and corrosion, especially on outdoor coils and parts. Inland homes deal more with dust. Either way, routine heat pump cleaning services help keep your system efficient and protected year-round.

Costs vary based on your system, but we always offer clear pricing with no surprise charges or upsells. We also have a USA Membership Plan that helps lower your long-term heat pump maintenance and repair costs.

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.

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.

Great service!! Jonathan was patient, kind, knowledgeable and extremely professional! I love Guthrie & Sons’ reminder system, notification of the technician enroute, the easy invoice system and immediate emailing of the findings, including detailed photographs of the work completed!! Highly recommend!

Last summer my air conditioner couldn't cool the house in the hottest period of summer. The HVAC team I was working with came in and said the coils were leaking, the unit was 20 years old. I requested quotes from 5 different companies, and the variation of prices was huge. I went with Guthrie and Sons for these reasons:
1. Local Company
2. Family Owned
3. Great presentation, no pressure
4. Good products
5. Competitive pricing
Just installed yesterday, so jury is still out on the system, but installation was thorough and great communication so far!

Carson and Michael were brilliant. The heat pump installation went smoothly, and they are really pleasant and trustworthy fellows. The day after it was installed, I had a plumber at my house. He looked at their work and was impressed. He said it was much cleaner than the way HVAC people usually do it.

First time prospective client of Guthrie and Sons. Very responsive staff in providing updates on my calls. Mario F. came over to check out my existing cooling and heating system and is very thorough and professional in providing necessary information related to repair/upgrades. Pending his quote, my experience with Guthrie and Sons is top notch and most highly recommended.

Updated review: Kareen, Daniel and Michael worked on the AC replacement, relocation of furnace to the attic and replacement of ductwork. Very professional and knowledgeable team in my opinion. Completed the work in a timely and very satisfactory manner.
