Power Your Home Smarter—With a Heat Pump Built to Save

Heat pumps aren’t like your typical HVAC setup—they don’t create heat, they move it. In cooler months, they pull warmth in; in warmer months, they push it out. That means one system takes care of both heating and cooling, all year long. It’s energy-efficient, space-saving, and perfect for San Diego’s mild climate. No more juggling a bulky furnace and AC—just one sleek, efficient unit. Whether you’re building from the ground up or just tired of your old HVAC system, a heat pump is a cleaner, smarter way to heat and cool your home.

At Guthrie & Sons Heating, Air & Solar, we make sure your new heat pump is installed the right way. We’re licensed, insured, and local—installing systems all across San Diego County, plus Temecula and Murrieta, too! We’ll help you choose the right heat pump, size it properly, and even guide you through rebates and tax breaks. Ready to explore a heat pump installation in San Diego?

How Does a Heat Pump Work?

How Does a Heat Pump Work?

Air source heat pumps don’t burn fuel—they use electricity to transfer heat from one place to another. In heating mode, they pull warmth from the outside air and move it indoors—even when it’s chilly outside. In cooling mode, it reverses direction like a traditional air conditioner, removing heat from your home and pushing it outside.

An air source heat pump system includes indoor and outdoor units connected by refrigerant lines, and it works with your new or existing ductwork to move heated or cooled air throughout your home.

Benefits of Installing a Heat Pump

Heat pumps aren’t just a trend—they’re the future. With energy prices climbing and HVAC technology evolving, more homeowners are moving away from the old furnace-and-AC combo.

Why juggle two bulky systems when one can quietly do both—and save you money in the process? Here are a few of the top reasons why you should install a heat pump:

Because heat pumps don’t generate heat, they use far less electricity than standard systems.

That means better efficiency and smaller utility bills.

You don’t need both a furnace and air conditioner anymore. One heat pump system covers all your heating and cooling needs in one setup.

Air source heat pumps reduce your home’s emissions and run without burning fuel. It’s a low-impact way to stay comfortable year-round.

Modern heat pumps are built for smooth, quiet operation and fewer unexpected repairs. They work in the background so your home stays peaceful.

Our region’s moderate climate is ideal for heat pump efficiency. Mild winters and warm summers make it easy for your heating and cooling unit to perform at its best.

Getting the most from your heat pump all comes down to how it’s installed. Even the best equipment won’t run like it should and save you what it should if it’s not sized, placed, and connected correctly. At Guthrie & Sons, we don’t rush the job. We do the prep work, double-check the details, and make sure everything’s set up to last. Because real comfort—and real savings—start with doing things the right way from the beginning.

How Much Does a Heat Pump Installation Cost?

The cost of heat pump installations depends on a few key things: your home’s size, layout, existing ductwork, and the type of system you choose. Labor, permits, and electrical upgrades can also affect the final number.

Get Year-Round Comfort With Affordable Financing

Yes, a new heat pump is an investment, but it doesn’t have to hit all at once. We offer seasonal specials and also have financing options to help you spread out the cost with monthly payments. Get the comfort you need now, and pay at a pace that better fits your budget.

Rebates and Tax Credits for San Diego Homeowners

Installing a heat pump in San Diego can qualify you for generous local rebates, California state incentives, and federal tax credits—sometimes totaling thousands in savings. We keep up with programs like TECH Clean California, San Diego Gas & Electric (SDG&E) rebates, and the Federal Energy Efficiency Tax Credit.

We Install the Best Heat Pumps for Your Home and Budget

We Install the Best Heat Pumps for Your Home and Budget

If you’ve started researching heat pumps, you already know—there’s a lot out there. You might be reading buying guides, comparing brands, or wondering which system works best with your existing HVAC. The good news? You don’t have to figure it all out alone. We’ve installed hundreds of systems across San Diego County and know what works in real homes with real energy goals.

Here’s a quick breakdown of what to consider—we’ll go over all this (and more) during your consultation.

These ratings tell you how efficiently your heat pump cools and heats your home. SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency—a rating between 15 and 18 is ideal for San Diego’s warm but not extreme summers.

HSPF (Heating Seasonal Performance Factor) measures heating efficiency—look for 8.5 to 10, which is perfect for our milder winter months. Higher numbers mean lower energy use and lower energy costs without paying for more power than you need.

What does having the right size heat pump mean? It’s not about the physical size of the unit—it’s about how much heating and cooling power your home actually needs based on your home’s square footage and other factors. Too small, and your system will run nonstop. Too big, and it’ll short-cycle, wasting energy and wearing out faster.

Home size is a key consideration. For example, a 1,500 sq. ft. house in San Diego might need a 2.5-ton heat pump, but that depends on insulation, windows, and more. We’ll run a Manual J load calculation to make sure your system is matched precisely to your home—not too much, not too little—just right.

Today’s heat pumps offer more than just comfort—they come with helpful built-in features. From Wi-Fi thermostats you can control with your phone to zoned temperature settings and programmable schedules, we’ll show you what fits your lifestyle. These extras make a big difference in day-to-day convenience and long-term energy savings.

There are different types of heat pump systems: air source heat pumps and ductless mini split systems. Air source heat pumps connect to your home’s ductwork and are great for full-home heating and air conditioning. They work best in homes that already have a central HVAC setup—or for new construction where ducts will be installed.

If your home doesn’t have ducts—or you want to cool just a specific space—ductless systems are a flexible alternative. Instead of using vents, it relies on small wall-mounted units that heat or cool individual rooms. They’re great for older homes, additions, garages, or anywhere it’s tough or expensive to run new ductwork. And if you want to keep your existing furnace but upgrade your cooling, a ductless mini split air conditioner lets you do just that—no major remodel required.

Maintenance and Repairs That Keep Your Heat Pump Performing

Maintenance and Repairs That Keep Your Heat Pump Performing

A new heat pump can last 10 to 15 years—or longer—but it needs a little help along the way.
Like any system that runs year-round, regular maintenance and the occasional repair are key to keeping it efficient and working like it should.

Skip the tune-ups, and small heat pump issues can turn into bigger (and more expensive) problems. Thankfully, keeping things running smoothly is easy when you’ve got a team you can count on. At Guthrie & Sons, we offer maintenance and repair services that help you get the most out of your system year after year. We’ll keep things running right—so you can relax and enjoy reliable comfort in every season.

Schedule Heat Pump Maintenance Twice a Year

We recommend having your heat pump system serviced twice a year—once in spring before cooling season, and again in fall before heating season. During these tune-ups, our licensed technicians check refrigerant levels, inspect electrical lines, clean indoor and outdoor coils, test airflow and temperature control, and look for early signs of wear. We’ll also make sure your air handler, outdoor unit, and thermostat are all working together like they should.

Ask About Our USA Membership Plan

Want to save money and make things easier on yourself? Our USA Membership Plan is made for homeowners like you. When you sign up, you’ll get two tune-ups per year, priority scheduling, and discounts on repairs if something goes wrong. You’ll also get reminders when it’s time for service—so you don’t have to keep track of it yourself. It’s a simple way to stay ahead of issues, avoid costly breakdowns, and make sure your HVAC system stays strong for the long haul.

Frequently Asked Questions

Yes, heat pumps work great in San Diego because the climate is mild year-round. They’re not ideal for severely cold climates, but here, they handle both heating and cooling with ease. That’s why so many homeowners are making the switch.

Routine maintenance is key, especially near the coast where salt and moisture can cause wear. Our HVAC technicians inspect the system, clean components, test performance, and check refrigerant levels. It helps extend your system’s life and keep efficiency high.

Yes—it can handle your home’s heating and cooling in one system. A properly sized heat pump heats in the winter and cools in the summer. No need to keep a separate AC or furnace.

That includes running electrical lines, placing the outdoor unit, mounting the indoor air handler, and setting up your thermostat. The final step is testing the full system to ensure your heat pump heating and cooling system runs properly. Only a trained HVAC professional should install heat pump heating and cooling systems.

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.

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.
