Maintenance Plans

Want Your Cooling System to Be More Reliable and Last Years Longer? We Can Make It Happen

Here’s what we see every summer: too many AC breakdowns that didn’t have to happen. Clogged filters, dirty coils, low refrigerant, worn-out parts—small issues that, if caught early, would have saved our customers from being stuck in a hot house and paying for big repairs. The truth is, most of these calls could have been avoided with routine maintenance.

That’s exactly why we created the Guthrie & Sons USA Membership. It takes the hassle out of scheduling and remembering, while giving you real benefits—scheduled tune-ups, automatic reminders, priority service when the heat is at its worst, and lower costs for repairs and service calls.

No matter what you rely on—central AC, a ductless mini split, or a heat pump—regular care makes a difference. It protects your warranty, stretches the life of your equipment, and helps you avoid the sticker shock of an early replacement. A new AC costs thousands. A yearly tune-up? Not even close.

Air Conditioning Services

Air Conditioning Services

Central AC is common in North Park and does a great job of keeping homes comfortable throughout every room. Our air conditioning services in North Park cover everything from checkups to big fixes, so your system keeps up with the heat year after year.

Schedule Online

Getting a new system isn’t about picking the biggest unit—it’s about choosing one that fits your home and how you use it. With our air conditioning installation in North Park, we’ll help you find the right match and set it up so it runs the way it should from day one.

Skipping tune-ups is one of the fastest ways an AC wears out. Our air conditioning maintenance in North Park includes cleaning, testing, and small adjustments that keep your system running smoothly. It’s a quick visit that can prevent costly repairs later.

When your AC blows warm air, makes odd sounds, or just can’t cool the house down, it’s time to call. Our air conditioning repair in North Park fixes common problems like bad motors, refrigerant leaks, and clogged drains so your system works like it should again.

After 10–15 years, most systems start breaking down more often and driving up your bills. With our air conditioning replacement in North Park, we’ll remove the old unit, install a new energy-efficient one, and make sure your home feels comfortable again.

Ductless Mini Split Services

Ductless Mini Split Services

Ductless mini splits are a smart option for older houses without ducts, smaller rentals, or add-ons like garage conversions, ADUs, or upstairs bedrooms that never cool evenly. Our ductless mini split services in North Park have everything you need to make these systems work for you.

During your ductless mini split installation in North Park, we mount the indoor unit high on a wall or ceiling and connect it to a compact outdoor condenser. The system is neat, quiet, and designed to blend into your space. You can cool a single room that never feels right, or link several units together to keep the whole home comfortable.

Think of our ductless mini split maintenance in North Park as keeping the system breathing. Dust and buildup on the filters or coils can choke airflow and make your unit work harder than it should. We handle the cleaning, flush the drains, and check the refrigerant so your system stays efficient and your rooms stay cool.

If your ductless air conditioner is more than 10–15 years old or struggles to keep rooms cool with frequent repairs, it’s likely time for something new. Our ductless mini split replacement in North Park gives you a modern, high-efficiency unit that’s built to handle San Diego’s hot spells.

Heat Pump Services

Heat Pump Services

A heat pump works like an air conditioner in the summer, pulling heat out of your home and releasing it outdoors. The difference is it can also reverse and provide heat in the cooler months. Many North Park homeowners are choosing them because they’re efficient, quiet, and do the job of two systems in one. Our heat pump services in North Park include installation, maintenance, repair, and replacement so your system is reliable year-round.

During your heat pump installation in North Park, we place an outdoor unit and connect it to an indoor air handler that moves cool air through your living space. Whether you’re adding one to replace an outdated system or building it into a remodel, we’ll make sure it’s the right size and set up properly for your home.

Because heat pumps often run every day in the summer, they need regular upkeep. Our heat pump maintenance in North Park includes coil cleaning, refrigerant checks, and small adjustments that keep your system efficient and prevent breakdowns when the heat is at its worst.

If your system blows warm air, runs constantly, or sends your energy bills up, you likely need heat pump repair in North Park. We handle issues like leaks, faulty sensors, and worn parts—and most repairs can be done in a single visit to get your cooling back fast.

After 12–15 years, most heat pumps lose efficiency and cooling power. With our heat pump replacement in North Park, we’ll install a high-efficiency upgrade that keeps your home cooler, lowers monthly bills, and gives you more dependable performance for years to come.

HVAC System Services

HVAC System Services

Your comfort isn’t just about AC—it’s about how your heating system and cooling system work together. In North Park, that might mean a central air conditioner paired with a furnace, a heat pump that does both, or ductless mini splits running in different rooms. Our HVAC system services in North Park are built to handle it all, keeping your setup reliable, efficient, and tailored to the way you use your home.

For first-time installs, remodels, or system upgrades, our HVAC installation in North Park starts with a full walkthrough of your home to understand its layout and energy needs. We size the equipment correctly, select the right heating and cooling system, and install it with care—paying attention to airflow, duct design, and thermostat placement. Every job is done to code.

Heating and cooling systems need upkeep to run their best. With our HVAC maintenance in North Park, we clean coils, replace filters, check connections, and make sure both your heater and AC are ready for the season ahead. Two simple visits a year can prevent breakdowns and keep bills under control.

Odd noises, weak airflow, or uneven temperatures often point to problems with your system. Our HVAC repair in North Park covers everything from blower motors and thermostats to refrigerant issues and leaky ducts.

Systems wear out after 12–20 years, and sometimes repairs just aren’t worth it anymore. With our HVAC replacement in North Park, we’ll remove the old equipment and set you up with a modern system—whether that’s a high-efficiency AC, a new furnace, or a heat pump that handles both heating and cooling.

As a Daikin Pro Elite Contractor, we offer HVAC system monitoring in North Park for Daikin systems. Remote monitoring lets us track performance, adjust settings, and catch small issues early. If a repair is needed, we show up ready with system data in hand, saving you time and hassle.

Frequently Asked Questions

In North Park, a window AC can cool a small apartment or single room for less up front. But if you’re cooling an entire house—especially older craftsman homes or multi-room setups—central AC is usually more efficient and less noisy. Running several window units often ends up costing more than one central system.

On San Diego’s hotter days, it’s common for your AC to run 12–16 hours to keep things comfortable indoors. If it’s running nonstop without cooling well—or barely running at all—that could mean a clogged filter, low refrigerant, or a system that’s not the right size for your North Park home.

With SDG&E’s time-of-use rates, electricity is most expensive during “on-peak” hours—generally 4 to 9 p.m. That’s also when your AC works hardest as homes hold onto the day’s heat. Pre-cooling earlier in the afternoon or setting your thermostat a little higher during peak hours can help cut costs.

If your AC is blowing warm air, taking forever to cool, or has ice forming on the outside lines, it might be low on refrigerant (commonly called Freon). Since refrigerant doesn’t just disappear, this usually points to a leak. A licensed technician can test the system, repair the leak, and recharge it properly.

Most AC systems are built to cool indoor air about 20°F below the outside temperature. If it’s 95°F outside, you can expect around 75°F indoors. Pushing it lower puts unnecessary strain on the unit and often just raises your SDG&E bill.

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!

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.
