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?

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

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

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.

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.

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.
