San Diego Furnace Installation Services That Keep You Comfortable for Years

At Guthrie & Sons, our San Diego furnace installation services include both gas and electric furnaces from trusted brands like Daikin, Rheem, and more. A well-installed furnace should heat evenly, run quietly, and last for years. One that’s poorly sized or installed improperly will continue to cause problems and cost you more and more money.

Our licensed team follows every manufacturer guideline, meets all San Diego city codes, and holds our work to the highest internal standards for safety, quality, and performance. Here’s what to expect during your furnace installation in San Diego:

We start with an in-home consultation to learn about your property and layout. Our technician checks available gas and electrical connections, measures your living space, and recommends a furnace size that fits your home’s design and insulation level. This step ensures the system we install heats efficiently without wasting energy.

Every home is different, so we help you choose the furnace that best matches your space, budget, and energy goals. We’ll explain the pros and cons of gas versus electric models and make sure your new system is properly sized. We design the setup to maximize airflow, minimize noise, and prepare for easy future maintenance.

Before your new furnace goes in, we prepare the site by checking clearances, installing a proper platform or stand, and ensuring ventilation and drainage are ready to meet code. If this is your first furnace, we also handle vent routing and any necessary ductwork modifications for safe and efficient airflow.

Once the site is ready, we position your new furnace, connect it to the duct system, and hook up gas, electrical, and venting components. We verify all connections, check for leaks, and follow manufacturer specs exactly so your warranty stays valid and your system operates safely.

If your home didn’t previously have a central heating system, we’ll design and install the ductwork to match your layout. Proper airflow design is critical for even heating, so we seal joints, balance vents, and ensure the system meets both comfort and efficiency standards.

Once installed, we test your furnace through multiple heating cycles, measure airflow, and fine-tune performance for steady heat across every room. We complete a full safety check and walk you through how to use and maintain your new system.

Keep Your Furnace Running Its Best with Repairs, Maintenance, and Our USA Membership Plan

Once your new furnace is installed, the best thing you can do is protect it with regular maintenance and repairs. Even brand-new systems need a yearly furnace tune-up to stay efficient, safe, and under warranty. Our furnace repair and furnace maintenance services help catch age and wear-related small issues early—like loose electrical connections, dirty burners, or airflow imbalances—before they turn into costly breakdowns. At Guthrie & Sons, we include a full inspection, cleaning, and performance test during each visit to keep your system running like new.

But we know life gets busy and scheduling your furnace maintenance can be easy to miss. To make things easier on you (something we love doing!), we created our USA Membership Plan. Members get set tune-ups for their heating and air conditioning systems, priority scheduling, discounted repairs, and lower service fees, and more. Talk to our team about signing up!

Frequently Asked Questions

In San Diego, the best time to buy a furnace is usually late spring or early fall—right before temperatures dip inland or the cool coastal nights return. Scheduling is much easier since it’s not as busy for HVAC companies like us. You’ll have more time to choose the right energy-efficient system for your home before you really need it.

Yes, homeowners in San Diego can take advantage of federal tax credits and local rebates for installing energy-efficient furnaces. Qualifying systems that meet ENERGY STAR® standards—typically with an AFUE rating of 97% or higher—may be eligible for up to $600 in federal tax credits. In addition, SDG&E and the State of California sometimes offer local rebates for high-efficiency heating systems, helping offset your furnace installation costs even more.

Most furnaces here last 20 years or more with proper care. Regular tune-ups, clean filters, and professional maintenance help extend the life of your furnace.

When choosing a furnace installer in San Diego, look for a licensed and insured contractor that’s local so there will be a faster response time. You want someone with 5-star reviews and a good reputation for both their workmanship and their customer service. Always ask about warranties, service guarantees, and any manufacturer certifications.

I’ve been using Guthrie & Sons for over 15 years. They installed my whole AC system and maintained it all those years and never had an issue. Well it was time for an upgrade and they’ve recently installed my second system. The team 15 years ago and the team this time around were both amazing, professional and clean. I can’t recommend them enough Matt, Ben, Christian and Bryan get 10 stars. They are a bit pricier but worth the investment when you have peace of mind and almost two decades of great service and no issues.

I had an excellent experience with Guthrie & Son AC & Heater Company. Their customer service was outstanding, and they took the time to answer all my questions thoroughly. Every technician who has worked on my AC/heater installation and now the ongoing service has been knowledgeable, respectful, and always on time. I highly recommend them to anyone in need of HVAC services!
I only wish the annual service was cheaper 🙂

I have a maintenance plan for my heat pump and air conditioner which Guthrie & Sons installed two years ago. I am very happy with my system as well as the maintenance plan. Wayne, one of their excellent technicians, just completed the Fall service and now the system is ready for winter use. He is knowledgeable and has been able to answer any questions I have about my system. In addition, the office at Guthrie & Sons is very responsive and follows through on any questions and concerns within 24 hours if not immediately. Great service from a great company.

Guthrie & Sons responded immediately to my online request, and was able to send someone out immediately. Zack, our technic-ian was very friendly, professional, knowledgeable and gladly answered all of our questions. He found the problem immediately, and left the work area clean and in good order. We would highly recommend Guthrie & Zack! They are real assets to our community.

I've been using Guthrie & Sons for over 10 years and two homes. I really like that they are a family-owned and an established business. Always professional, on time, and always quality work. I've used their services from simple routine maintenance to having a new AC installed.I've never had a bad or even mediocre experience; I'm just always overall pleased with their work.

We needed a new A/C and furnace system. Vlad came by to listen and assess our needs, recommend our new Daikin, and put forth our best estimate.

Carson C. and Michael J. came by to install our unit. They were on time, extremely professional and worked diligently to complete everything. They listened to our needs throughout and made adjustments to our specifications. Carson did not leave until we were totally happy with our unit.

This was a great experience all around and I gladly recommend Guthrie and Son's for all your HVAC needs.

Rachel Phillips

We recently had our A/C replaced by Guthrie & Sons, and I cannot recommend them highly enough. After getting five different bids, Guthrie & Sons stood out immediately—not just on price, but on expertise and professionalism. They even brought their engineers out to ensure the work could be done the right way, which gave us tremendous peace of mind.

From start to finish, their team was outstanding. They worked incredibly hard, treated our home with respect, and left everything spotless—truly the cleanest job site I’ve ever seen after a major project. The installation itself was seamless, and the quality of their work shows in every detail.

If you’re looking for a company that combines deep knowledge, excellent craftsmanship, and genuine care for their customers, Guthrie & Sons is it. Absolutely five stars across the board!

We had a wonderful experience with Guthrie and Sons. Anthony was our estimator and he did a very thorough job of explaining all of our options! Matthew, Bryan, and Isaiah were our installers and they were very efficient, capable, and personable. Our home did not have an existing HVAC system so they had to build the whole thing in an older house that had undergone several additions. We were up and running in just three days. They left the worksite clean at the end of each day. We highly recommend Guthrie and Sons!

Kareen did an outstanding job with our HVAC system. From start to finish, he demonstrated professionalism, patience, and a strong commitment to getting the job done right. Even when faced with several unexpected challenges, he handled each one with skill and determination, never compromising on the quality of his work.

What really stood out was his problem-solving ability and willingness to go the extra mile to ensure everything was operating as it should. He communicated clearly throughout the process, kept us updated, and made sure we felt confident in the work being done.

It’s not often you come across someone who combines technical expertise with such a strong work ethic and positive attitude. We’re very grateful for his efforts and would highly recommend Kareen to anyone needing reliable HVAC service.

Professional from beginning to end

Vlad came out to provide an estimate and was able to size an HVAC system that worked well for my house.

They installed it quickly, without issue and helped me set up an app on my phone to control.

The system is working great to heat and cool my house and is whisper quiet.

Highly recommend going with Guthrie and Sons if you want a high quality experience for large and important purchases.

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!

LeRoy Lafferty

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.

Nannette Moyer

17:41 29 Jul 25

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.

Meghan Venanzi

23:31 22 Jul 25

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!

Laurie Edwards

22:10 16 Jul 25

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.
