Heat pump systems offer an efficient way to heat and cool your home year-round using heat transfer rather than combustion. These systems move heat in and out of your space depending on the season—keeping you cool in summer and warm in winter. Because they don’t rely on gas, heat pumps are a cleaner, more energy-efficient choice for your heating and cooling systems. At Guthrie & Sons, our heat pump services in Rancho Santa Fe make it easy to install and care for these amazing systems.

At Guthrie & Sons, we tailor our HVAC services in Rancho Santa Fe to match your system, your space, and your lifestyle—so things feel just right year-round.

We know comfort looks different for everyone, and we’re here to help you find what feels right.

Frequently Asked Questions

How do inverter heat pumps work?

Inverter heat pumps adjust their speed automatically to match your heating or cooling needs. That means steadier temperatures, lower energy use, and quieter operation compared to traditional systems.

We look at your home’s size, layout, insulation, and how you use each space. Then, we walk you through the best HVAC options, from heat pumps to central heating and cooling systems.

In Rancho Santa Fe, the coastal air can lead to excess indoor moisture—especially in well-sealed or shaded homes. A whole-home dehumidifier helps prevent musty odors, mold growth, and that sticky, uncomfortable feeling. We’ll help you decide if it’s the right fit for your space.

Watch for weak airflow, unusual noises, warm air, or higher energy bills. These are all signs your AC might need repairs—and we’re happy to take a look and get it sorted quickly.

Yes. Most heating and cooling system warranties require proof of routine maintenance. We handle that for you with reminders, records, and tune-ups that keep your system protected.

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 Company2. Family Owned3. Great presentation, no pressure4. Good products5. Competitive pricingJust 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.

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.

Jonathon is a great technician. He is very willing to answer any questions and explains things very well. He is very transparent with letting us know cost, finance options, different furnace models and anything else we want to know. I would highly recommend him to anyone looking for furnace repair or replacement.

Guthrie and Sons took on the challenging project of installing an HVAC system at St. George's Serbian Orthodox Church of San Diego, CA. They were the only company among the six we consulted that saw the project through to the end. The members of our congregation are not just happy, but thoroughly satisfied with the heating and air conditioning. The system, split units/floor units with condensers outside, was installed with minimal intrusion onto the church's artwork. Despite the project taking longer than expected due to permit delays, the results were well worth the wait. We highly recommend Guthrie and Sons Heating and Air.

Got recommended this company by my boss who had a whole mini split system installed in his house. Was able to schedule a service appt same week. On morning of service Daniel W. shows up, listens to all of my concerns, and gets right to work. Daniel was able to investigate the problem, took his time making sure he's eliminated all other possible issues before coming up with a recommendation to my original proposal. Fixes up the issue then checks to see if it is working properly. Not only that, he stays with me few more minutes and addresses all the questions I had for him regarding the system, as a whole. Absolutely amazing.I'll be calling back to schedule maintenance services with them going forward. They won me as a customer.
