When to Replace Your Heat Pump

When to Replace Your Heat Pump

If you’re searching for a “heat pump replacement service near me,” chances are something’s not right and you're trying to figure out what to do. Or, maybe another contractor recommended replacement, but you're still unsure. That's okay. It's good to ask questions!

At Guthrie & Sons, we help you make the right call—not the rushed one.

Heat pump repairs might make sense if:

  • Your unit is under 10 years old
  • Issues are minor and not happening often
  • It still keeps your home reasonably comfortable

A heat pump replacement may be smarter if:

  • Your system is 12–15+ years old
  • Repairs are adding up or getting more serious
  • You're paying more on energy bills but not experiencing the same level of comfort

We’ll look at everything and give you honest, expert guidance—so you can feel good about whatever you decide.

Free Online Heat Pump Replacement Cost Calculator

If your old heat pump is on the way out, it helps to know what kind of cost you’re looking at. While we’re always happy to provide a free in-home estimate, we also offer a heat pump replacement cost calculator for when you just want to run the numbers. It’s quick, easy, and gives you a realistic idea of your heat pump pricing.

You might be able to save money through rebates or energy efficiency programs—and we’ll help you find and apply for them. If covering the cost all at once feels tough, we also offer flexible financing to make it more manageable. From your first question to the final walkthrough, Guthrie & Sons is here to make replacing your heat pump simple and stress-free.

What to Expect When Replacing a Heat Pump System

If you’ve kept up with maintenance and tune-ups over the years, there’s a good chance your heat pump made it through its full lifespan—10 to 15 years, sometimes even longer. That also means it might’ve been a while since you last shopped for one.

Heat pump technology has come a long way, and we’re here to help you understand it all. Here’s what to expect during the heat pump replacement process—and what we recommend:

We don’t just guess based on square footage or copy the specs from your old unit. Our team takes time to understand how you use your home, how it’s insulated, and whether anything’s changed since your last system was installed.

We perform a Manual J load calculation to properly size your heat pump—because a system that’s too big or too small will cost you more and work harder than it should.

Heat pumps today come with a wide range of features—from variable-speed motors and inverter technology to smart thermostats and high-efficiency SEER2 (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings.

We’ll walk you through what’s actually useful for your home, your habits, and our climate—not just what’s flashy.

Once you’ve selected your system, we handle everything—from removing the old equipment to installing the new indoor and outdoor units, running refrigerant and electrical lines

We’ll show you how to use your new system, answer any questions, and make sure everything is working perfectly. Once your install is done, we’re still your go-to team for service, maintenance, and repairs.

Replacing a heat pump isn’t just swapping out two boxes. It involves electrical lines, refrigerant, ductwork, your thermostat, and more. DIY installs can lead to leaks, safety issues, or expensive mistakes that cost more to fix later. Let Guthrie & Sons handle it right the first time so your next heat pump works like it should and your money is protected.

Protect Your Heat Pump With Regular Maintenance That Pays Off

Heat pumps work year-round in San Diego—cooling your home through hot stretches and keeping things warm when the temps drop. Between coastal air, dust, and steady use, even the best system will start to wear down over time. If yours stops heating or cooling the way it should, we’re here to handle the heat pump repair.

But to keep your system running longer and avoid breakdowns, regular maintenance is key.
Our heat pump tune-ups include full system checks, cleaning, refrigerant testing, and performance checks. We’ll catch small issues before they turn into bigger, more expensive ones.

Want to do yourself (and your wallet) a favor? Join our USA Membership Plan for scheduled tune-ups, repair discounts, priority service, and more. It’s the easiest way to protect your system—and your comfort—year after year.

Frequently Asked Questions

If your system runs constantly, struggles to keep your home comfortable, or your energy bills keep rising, something’s off. You might also hear strange noises or notice poor airflow. These are signs it’s time for a repair—or possibly a full replacement.

That depends on your home size, system type, and the features you want. Most San Diego homeowners can expect to spend several thousand dollars. We’ll give you a clear quote—and help you find rebates, incentives, or financing if needed.

Most replacements are completed in a single day. If there are ductwork changes, electrical updates, or multiple zones, it may take a bit longer. We’ll give you a full timeline upfront so there are no surprises.

Yes—often, we can relocate one or both units depending on access and layout. We’ll assess your space and make sure the new placement works for both performance and service access.

If relocation isn’t ideal, we’ll walk you through your best options.

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.

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.
