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.

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.

We had Rob from Guthrie & Sons come out to repair one of our A/C units. Rob was very friendly and professional. Rob resolved the problem quickly.
As far as price goes, I paid a higher flat fee 12 years ago from one of the larger local companies. I'm very impressed with pricing and quality of work.

I highly recommend Guthrie & Sons and Rob.

Great experience working with Guthrie & Sons from start to finish. Vlad was awesome. He was incredibly knowledgeable and explained everything in detail. Stark contrast from other companies we received bids for.

Christian and his crew did a great job on the install everything was smooth from start to finish.

I would definitely recommend this company here in Murrieta.

Guthrie & Sons has always been super professional and knowledgeable about our system. They did the install a few years ago and have continued to maintain it for us. This year we noticed that our system wasn't performing as well, so when Wayne came out, he noticed a likely leak and was back 2 days later to find and fix it. He was quick, professional, and just extremely nice! 100% recommend.

Called one of the "big guys" in town and the estimate to do what needed to be done to diagnose my problem was nearly 1/2 the cost of the system when I purchased it and had it installed 5.5 years ago, I found Guthrie & Sons and they came out the same day and did the same work for 1/4 the price I was quoted for the same exact work! Daniel was friendly, honest and quickly got my system working as expected. I even purchased the service plan so I don't have future problems. I highly recommend these guys, they were awesome, don't get ripped off call Guthrie & Sons!!!

Matt and Bryan are truly the A-Team! Their teamwork was outstanding and the workmanship was meticulous. The air handler was carefully installed, wiring neatly secured, plenum perfectly fitted, and the condenser precisely positioned and leveled for proper clearance and vibration control. The line set was pressure-tested and vacuumed as well. They also left the work area clean and neat.

Please congratulate them for a job well done!

Guthrie and Sons was very professional and communicative. Matthew and Bryan did incredible work, and followed up with a lot of testing to make sure my new unit was functioning well. They went above and beyond to ensure that things were done correctly. I could tell their standards were extremely high, and I felt relieved seeing how much care they took in their installation. I’m very pleased with the result!

After dealing with several HVAC companies, Guthrie & Sons clearly stood out as the most ethical, honest, and reliable. From the very beginning, their approach felt transparent and genuinely focused on what was best for us—not on upselling or unnecessary replacements.

We worked with Vlad T., who had previously been out to our home and saved us tens of thousands of dollars by getting our existing AC unit up and running when other companies were pushing for a full replacement. That experience alone earned our trust.

Now that we’re finally ready to purchase new units, there was no question that Guthrie & Sons was the only company we would consider, and Vlad was the obvious choice. He was extremely professional, punctual, and exceptionally knowledgeable, taking the time to explain options clearly and thoroughly. His expertise and honesty made the entire process straightforward and stress-free.

If you’re looking for an HVAC company you can truly trust—one that values integrity, quality workmanship, and customer service—I cannot recommend Guthrie & Sons and Vlad T. highly enough. This is how service should be done.

The layout of my condo made installing splits challenging, and before I met with Guthrie and Sons, three companies either told me that it couldn't be done. Vlad studied my apartment until he found a way to install with minimal openings in the walls and without a second condenser. Mallory, who works in the office, always followed through and advised me when I ran into a hiccup and needed detailed plans for the city. My HOA appreciated Guthrie and Sons' thoroughness and was so impressed with the design, that another resident who had been wanting splits for years, decided to install splits at the same time. The team that came in was knowledgeable, professional, and hard working. They finished a day ahead of time. I'm thrilled with the way everything looks and works.

This is by far the best company for your HVAC needs. They are honest very caring. Good fair pricing and got the job done efficiently and on time. I also signed up for their bi-yearly service which they performed the winter one and went very well. Thanks

I’ve been using Guthrie & Sons for over 15 years. They installed my whole AC system and maintained it all those years and never had an issue. Well it was time for an upgrade and they’ve recently installed my second system. The team 15 years ago and the team this time around were both amazing, professional and clean. I can’t recommend them enough Matt, Ben, Christian and Bryan get 10 stars. They are a bit pricier but worth the investment when you have peace of mind and almost two decades of great service and no issues.

I had an excellent experience with Guthrie & Son AC & Heater Company. Their customer service was outstanding, and they took the time to answer all my questions thoroughly. Every technician who has worked on my AC/heater installation and now the ongoing service has been knowledgeable, respectful, and always on time. I highly recommend them to anyone in need of HVAC services!
I only wish the annual service was cheaper 🙂

I have a maintenance plan for my heat pump and air conditioner which Guthrie & Sons installed two years ago. I am very happy with my system as well as the maintenance plan. Wayne, one of their excellent technicians, just completed the Fall service and now the system is ready for winter use. He is knowledgeable and has been able to answer any questions I have about my system. In addition, the office at Guthrie & Sons is very responsive and follows through on any questions and concerns within 24 hours if not immediately. Great service from a great company.

I've used their services from simple routine maintenance to having a new AC installed.I've never had a bad or even mediocre experience; I'm just always overall pleased with their work.

We bought our HVAC system from Guthrie & Sons. They have been monitoring our system online and later noticed a heat sensor issue.

Zach M. came by and installed on new one. He was extremely professional and completed the installation promptly.

This was another great experience all around and I gladly recommend Guthrie and Son's for all your HVAC needs.
