Trusted Heating Installation & Replacement

Our heating replacement process involves removing the old unit, reviewing your system options with you, and installing the new heater properly. If you’re not sure which heating system you want, we can help you choose between:

  • Heat pumps: These are a popular choice in San Diego because of their ability to both heat and cool a home.
  • Split systems: These systems have the AC unit outside and the heating unit inside, both connected to your thermostat.
  • Mini-split systems: These are smaller versions of split systems designed for small homes or single rooms.
  • Packaged units: This large unit houses an AC unit and a heater in one space.

Benefits of Installing a New Heating System

Installing a new heating system in your home can be beneficial in many ways. Here are a few perks:

  • You’ll save money on energy bills: A new heating system will be more energy-efficient, meaning it will likely cost you less to run each month.
  • You can get rebates for being eco-friendly: There are various rebates available for new heating equipment installations, and we can help you find the ones you’re eligible for.
  • You’ll avoid constant repairs: A new heating system means you won’t have to deal with constantly repairing your old one.
  • You’ll have a more comfortable home: A new heating system will heat your home more evenly.

Heating Systems We Offer

Whether you’re looking for a traditional split system, a high-efficiency heat pump system, an “all-in-one” packaged unit, or a mini-split system with individual climate control, Guthrie & Sons has a heating solution for you. View our heating systems below.

Split
Systems

A traditional heating and air system consists of one indoor unit, which is your furnace or heater, and one outdoor unit, your air conditioning condenser. 

Heat Pump Systems

Heat pumps are becoming increasingly popular. Considering most San Diego homes now have solar, a heat pump is the perfect solution, as it can run on electricity, not natural gas.

Package
Units

Package units are an “all-in-one” solution where the heating and cooling elements are combined into one single unit. Ideal for when you want to save interior space, as no furnace is needed. 

Mini-Split Systems

Depending on your home, you may not be able to install ductwork, which is necessary for directing airflow. With mini-splits, you can install a unit in any room, allowing you to individually control the temperature.

Heating Installation FAQs

Do I need a heating system in San Diego's mild climate?

While the weather doesn’t get as cold as in other parts of the country, having a heater is still recommended. Heaters can help balance the humidity in your home and keep it at a comfortable temperature, especially at night when it’s coldest.

Heat pumps are a popular choice for San Diego homes due to their energy efficiency and size. However, the type of heater you need depends on your home’s size, available space, and other factors.

Yes, installing a new energy-efficient HVAC system can potentially qualify you for various state and federal rebates.

Our two old furnaces needed replacing and so we contacted Guthrie & Sons because of their good reputation. They sent Zach the next morning. He quickly verified that our two furnaces were beyond repair and Guthrie could supply and install suitable replacement funaces. He also suggested and explained alternative solutions, but we eventually decided to go ahead with furnace replacement. As soon as we notified Guthrie & Sons of our decision they arranged for Cristian and Pablo to come to our house the next day. They did a good job, explained clearly how to operate the new furnaces and thermostats, and were respectful of our house.

Daniel was quick and professional. Fixed our AC problem in an hour and the price was very transparent and beyond fair. Didn’t push the subscription maintenance service, simply said it would be a good idea due to the age of our unit. Highly recommend!

We had to replace a thermostat that had gone bad. In the old days, I could do it myself. Now, though, the programming of the thing requires technical knowledge that I don’t have. The Guthrie guy that did the job was courteous, professional, and as fast as anyone could be. This has been our experience with Guthrie & Sons for every repair, retrofitting, and equipment replacement that they’ve done for us over quite a number of years now.

Carson Snyder and co-worker (Pablo?) did a great job on the installation of the mini-split cassette. They're hard working, they clearly knew what they were doing, polite, cleaned up afterwards, true professionals. I'd gladly recommend these two gentlemen. However, the Company was not good at keeping me informed although I mentioned to the salesman up front that I was information driven. They were short on details and communicated seldom. Anthony did tell me about the government program available that reduced my cost. I wouldn't have known about it if he didn't mention it. The City did approve their work and signed off on the permit which is an indication of the job done right. I think the Company can improve their customer service

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.

Great local family business. And you actually get a live person when you call... And the technician was great and they come out quickly. No up selling too. He gave me two different price options on fixing my problem... band aid cheaper way or replacement. Great service.

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.
