Many of the older homes were built before central air was standard, so ductwork can be limited and insulation thin. Even newer builds can trap heat in upstairs bedrooms or sun-soaked living rooms.

Maintenance Plans

Keep Your AC Running Longer and Your Energy Bills Lower

Most AC systems don’t just quit one day—they slowly lose efficiency when they’re not maintained. That extra wear can lead to higher energy bills, more repairs, and having to replace the unit sooner than you expected. Regular air conditioner maintenance goes a long way toward keeping your home comfortable and your wallet happy.

Our USA Membership makes it so easy to keep up with both your heating and AC tune-ups. We service all leading brands, and you’ll get reminders when it’s time for maintenance, plus discounts on repairs, lower service fees, and priority booking.

Remember, if your AC unit is still under warranty, yearly maintenance is usually required to keep it valid. This plan helps you stay covered, avoid surprise breakdowns, and get the most life out of your system. You paid good money for it, now protect it the best way possible!

In Clairemont, those sunny San Diego days can warm up fast—especially when the breeze from the bay doesn’t quite make it inland. Whether you’re cooling down after a morning at Tecolote Canyon or trying to keep the house comfortable during a late-summer heat wave, you need an AC that works when you do.

At Guthrie & Sons, we handle everything from quick repairs to full system installs, plus the regular tune-ups that keep your cooling running strong. However you beat the heat, we’ve got the service to make it happen.

Air Conditioning Services

Air Conditioning Services

Central air conditioning is a favorite in Clairemont. It’s a dependable way to cool your whole home while keeping the noise down and energy use in check. We offer complete AC services to keep your system performing—whether it’s brand new or has been cooling your home for years.

Schedule Online

With our air conditioning installation service, we help you find the right AC for your space. Bigger isn’t always better—what matters is a unit that fits your home, keeps energy bills in check, and cools every room evenly. We’ll explain your options for efficiency, performance, and noise levels so you can make a smart choice.

Our air conditioning maintenance service keeps your system in top shape with a full checkup and cleaning. We’ll wash the coils, replace filters, tighten loose parts, and make sure everything is running smoothly. A yearly tune-up helps your AC cool better, last longer, and avoid those mid-summer breakdowns.

If your system isn’t cooling well, blows warm air, or makes strange noises, our air conditioning repair service can fix the problem. We handle everything from low refrigerant and clogged drains to worn-out parts and electrical issues. We’ll find the issue quickly and get your home feeling comfortable again.

When your system reaches the 10–15 year mark or repairs start costing more than they’re worth, our air conditioning replacement service can help. We’ll guide you in choosing a modern, energy-efficient AC, handle the full installation, and make sure it’s set up to keep you cool for many summers ahead.

Ductless Mini Split Services

Ductless Mini Split Services

A ductless mini split can be the perfect solution for Clairemont homes that don’t have central AC—or for adding air conditioning to spaces your existing system doesn’t reach. They’re popular for upstairs bedrooms that heat up in the afternoon, enclosed patios, backyard ADUs, converted garages, and home offices. We provide full ductless mini split installation, maintenance, repair, and replacement services.

With our ductless mini split installation service, you can cool (and even heat) a space without adding ductwork. We mount the indoor unit high on a wall or ceiling, connect it to a small outdoor unit, and size it for the room so it reaches your ideal temperature quickly and maintains it consistently.

Our ductless mini split maintenance service keeps your system in top condition. We’ll clean or replace filters, flush the drain lines, check refrigerant levels, clean the coils, and test electrical components. This helps your mini split stay efficient and significantly reduces the chances of breakdowns.

If your mini split is struggling to keep up, needs frequent repairs, or is over 10 years old, it may be time for a ductless mini split replacement. New models are quieter, more energy-efficient, and better at maintaining consistent temperatures. We’ll help you choose the right system for your space, remove the old one, and install the new unit so it’s ready to deliver reliable comfort from day one.

Heat Pump Services

Heat Pump Services

A heat pump can cool your Clairemont home just like an air conditioner, but it does it more efficiently by moving heat out instead of forcing cold air in. The result? Consistent, comfortable temperatures and lower energy use. We handle everything from heat pump installation and seasonal tune-ups to quick heat pump repairs and full heat pump replacements. We also install heat pump water heaters that can help lower your utility bills!

With our heat pump installation service, we start by finding the right spot for the outdoor unit—usually along a side wall, on a concrete pad, or tucked in a shaded area to help it run more efficiently. Indoors, the air handler is placed to give the best airflow throughout your living space. We size the system for your home’s layout and cooling needs, then install it with features like variable-speed compressors, smart thermostats, and ENERGY STAR® efficiency ratings.

Our heat pump maintenance visits are thorough. We clean the evaporator and condenser coils, check refrigerant pressure, lubricate moving parts, tighten electrical connections, flush the condensate drain, and test the reversing valve to make sure it switches smoothly between heating and cooling. We also inspect the fan motor, thermostat, and duct connections so your system can keep you cool without wasting energy.

When something goes wrong, our heat pump repair service gets to the root of the problem fast. Common issues include worn contactors, faulty capacitors, damaged fan blades, refrigerant leaks, and failing sensors. We carry most replacement parts on our trucks so we can often fix the issue in one visit—whether it’s a small electrical fault or a major cooling performance problem.

If your system is over 12–15 years old, makes unusual noises, or struggles to cool even after repairs, it may be time for a heat pump replacement. We’ll remove the old system, check that your ductwork or air distribution is ready for the new unit, and install a modern, energy-efficient model that’s sized to keep your home cool without running constantly.

HVAC System Services

HVAC System Services

Your HVAC system isn’t just one piece of equipment—it’s the combination of heating, cooling, airflow, and controls that keep your home comfortable year-round. In Clairemont, that might mean a central air conditioner paired with a furnace, a heat pump, or even ductless mini splits in certain rooms. We design, install, maintain, repair, and replace HVAC systems so they match how you actually use your home.

Our HVAC installation process starts with a full walk-through of your home to understand how air moves through each space. We calculate the right system size, choose equipment that balances efficiency and performance, and make sure the ductwork design supports even cooling and heating. Every installation is to code, tested for airflow, and set up for years of reliable use.

Routine HVAC maintenance keeps your system running at its best. During each visit, we clean the coils, replace or wash filters, inspect motors and belts, test safety controls, and check refrigerant levels. We also look for early signs of wear—like loose electrical connections or small leaks—before they turn into major repairs. Two visits a year, once before summer and once before winter, help keep energy costs down and comfort levels up.

Strange smells, loud rattles or buzzing, weak airflow, or rooms that never seem to reach the right temperature are all signs that something’s off with your HVAC system. Our HVAC repair team quickly tracks down the cause—whether it’s a refrigerant leak, worn part, thermostat problem, or another hidden issue—and makes the fix. We arrive ready with tools and common replacement parts, so in most cases, your system is back to normal the same day you call.

When your system is 12–20 years old or needs repair after repair, our HVAC replacement service can upgrade you to something quieter, more efficient, and better suited to your comfort needs. We remove the old unit, inspect and adjust the ductwork if needed, and install the new system so it’s immediately ready to go.

As a Daikin Pro Elite Contractor, we offer HVAC system monitoring for Daikin equipment. This allows us to check your system’s performance remotely, fine-tune settings for efficiency, and catch potential issues early. If you ever need a repair, we already have system data on hand, which means a faster, smoother service visit.

Frequently Asked Questions

A single window AC will cost less to buy and can use less electricity if you’re cooling just one room. But for an entire home, central air is usually the better deal over time. If you find yourself running multiple window units, central AC will often cool more evenly, run more quietly, and use energy more efficiently.

In Clairemont, most summer days don’t push your AC to run nonstop thanks to the coastal breeze—but during late-summer heat waves or unusually warm days, it’s normal for it to run 8–12 hours or more to keep up. If it’s running constantly even on mild days, or barely turning on when it’s hot, you may need repairs or extra maintenance.

Electricity tends to cost the most in the late afternoon and early evening—usually between 2 p.m. and 7 p.m.—when demand is at its peak. That’s also when your AC has to work the hardest. If your utility company uses time-of-use pricing, pre-cooling your home earlier in the day can help you save.

If your AC is blowing warm air, takes much longer than usual to cool the house, or you notice ice forming on the refrigerant lines, it could be low on refrigerant—what many people call Freon. At Guthrie & Sons, we always check for leaks first, because refrigerant doesn’t just disappear on its own. If there’s a leak, we’ll locate and repair it, then safely recharge your system so it’s cooling the way it should again.

The “20-degree rule” is a guideline that says your AC can lower the indoor temperature by about 20 degrees compared to the outside temperature. So if it’s 95°F outside, hitting 75°F indoors means your system is working as designed. Trying to go much lower can strain the system and drive up your energy bills.

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.

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.
