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.

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.

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.

My experience with Guthrie & Sons has been excellent, and I am pleased to write a very favorable review about it. They replaced three air conditioners and three propane furnaces with new equipment that utilizes heat pump technology. I had met with other companies and I was close to coming to a conclusion, when a friend recommended Guthrie & Sons. He told me that they are hyper focused on customer service from beginning to end.

Their customer service started with the on line completion of a basic information form. Shortly after submitting that form, I heard from Zach who scheduled an appointment at my home.

I had already met with three other HVAC contractors, and for that reason, I had some basic information about the systems available and how heat pumps work and whether propane furnaces should also be installed. I signed a contract on a Friday. By Wednesday of the next week they had completed the installation. Wow.

The installation of one of the furnaces in the attic caused minor damage to the drywall. THEY BROUGHT IT TO MY ATTENTION and told me a drywall contractor would be in touch regarding its repair. Two days later it was repaired.

Since installation, the equipment (heat pumps from Bosch) has been working great and I am optimistic about the future. Meanwhile, their pricing, warranty and terms are far superior to their competitors.

Since this is an unusually long review and so favorable, let me add this: This is my honest, uncompensated opinion. I have no relationship with anyone at Guthrie & Sons other than the contract we executed.

We recently had Guthrie and Sons install a Mini-Split system in our home. The entire process was handled professionally with no issues occurring at any time. The estimator (Vlad) went through options with us but let us evaluate the best solution for us with zero pressure. The installation team (Matthew and Aaron) showed up on time, reviewed the scope of the job, made sure they understood what we wanted, and then proceeded to complete the installation exactly as discussed. They asked for my input as needed so there were no surprises when the job was completed.
They respected my property and made sure everything was left at least as clean was when they arrived. The job was completed on time and as promised and they reviewed the details of the system and its use clearly. I would definitely have Guthrie and Sons do other electrical/HVAC work should the need arise.

I have been in the construction industry in San Diego for over 50 years. I owned my own contracting company for over 40 years. I have seen all levels of customer service in my years. The level of customer service from Guthrie and Son’s is among the best I’ve ever seen and received. Every time I hear anyone asking for a referral for HVAC work I immediately give them your number. When I recommend a company I in essence am putting my name and reputation on the line. I refer them with 100% confidence in the service they will receive. Thank you very much for your legendary service.

We first hired Guthrie and Sons to replace a furnace after comparing proposals from several heating and air companies. They’ve since been back for annual check ups, and today Kareen came to diagnose and resolve an issue with our mini-splits. My experience each time, including today, is that they hire friendly, knowledgeable people who do good work. They’ve never tried to upsell or do anything unnecessary, which is the way it should be. I’d recommend them to anyone who asks.

My AC was not working for seven months. Three other companies tried to fix it with no success. Don’t make the same mistake I did—go straight to Guthrie & Sons! They are absolutely worth every penny.
