Tria Air Conditioning Pros should be your first choice for heater repair services. I reached out to them when I needed an extra return installed in my son's room (a problem from an outdated heater design). They dispatched Preston on a weekday morning. After briefly explaining the issue of insufficient airflow to the front bedroom, Preston quickly adjusted the air vents resulting in immediate improvement. This was a problem I had been trying to get solved by my previous company for the last 18 months, but none of their personnel could fix it. Preston took the time to explain why this was happening, thoroughly checked everything, and within an hour, I had a reasonably priced quote for the necessary work. We explored several options and there was no pressure on the work I decided to go ahead with. To my surprise, later that morning, I received a call informing me that they could send someone over on the same day to rectify the issue. Trenton and Bryson were at my house before 7:00 AM and had finished the return duct work by 8:30 AM. We could instantly feel a difference in the airflow in my son's room. They even left some replacement filters and explained what they had done and what to expect. All three of these gentlemen were highly professional, had great personalities, and truly cared about resolving this longstanding issue. I won't hesitate to contact Tria Air Conditioning Pros for my future heater repair needs. Their service and customer care were truly commendable. The scheduling process was also smooth and tailored to suit my needs. Great job, guys!

I have an old heater that I thought was completely broken. The technician from Tria Air Conditioning Pros, Bryson, did an excellent job diagnosing the problem and pinpointing the issue. He thoroughly inspected the entire system, made the necessary repairs, and was very friendly. He honestly informed me that my heater was still working but nearing the end of its life. Since I can't afford a new heater at the moment, his repairs have given me a chance to save up some money. The customer service was outstanding, and the prices were reasonable. I will definitely use their services again.

I have trusted Tria Air Conditioning Pros over the years for the maintenance of my furnace system. They were the original installers of the furnace in Fullerton homes. After 46 years, I found myself needing a furnace replacement. Trenton and Bryson, the technicians, did an exceptional job. They meticulously replaced all the equipment, and my furnace is now running efficiently and comfortably. They demonstrated pride in their work, were extremely thorough, and they left the work area spotlessly clean! I appreciate the well-done job and Tria Air Conditioning Pros' remarkable service over the years. For all your furnace repair needs, I wholeheartedly recommend them, particularly for furnace heating.

we were away when our nest thermostat showed the temperature inside was dropping into the 50s, just as a cold snap was coming. a quick call to Tria Air conditioning Pros and they were able to repair our heater fast. our son-in-law left a key so they could get in. greyson came, fixed the furnace, got everything running, and secured the house in about an hour! this saved us money and hassle. we are so happy and impressed with their professional work and great service!

Preston was fantastic! When my furnace stopped working, I scheduled an appointment for noon and he arrived right on time. He was friendly and professional. Preston quickly figured out what was wrong and repaired my furnace in less than two hours, and the cost was very fair. Later on, my old thermostat caused another problem and part of my house wasn’t getting heat. I reached out again, and Preston came back and replaced the thermostat at no extra charge. I highly recommend their furnace repair services and will definitely call Preston for any future heating and cooling needs!

We've relied on Tria Air Conditioning Pros for several heater repairs and maintenance services at different homes. Their team has also handled A/C diagnosis and repairs, plus regular tune-ups for both heating and cooling systems. The membership plan is really helpful—it schedules two tune-ups per year for our heater and A/C, which makes it easy to keep everything running smoothly. It gives us peace of mind knowing our systems are well maintained and helps extend the life of our appliances, especially with how warm it gets in Fullerton. The technicians, like Bryson and Greyson, have always arrived on time, acted professionally, and answered all our questions patiently. Because of their dependable service, we only trust them for our heater repairs and other HVAC needs.

We highly recommend this company for any heater repair and HVAC work. They helped us out on two different occasions—first by fixing our heat pump, and then by relocating our HVAC system and installing a new air register. Both times, the service was quick, professional, and very clean. The technicians really knew what they were doing, and the prices were fair. Before we called them for the heat pump repair, another HVAC company told us we had a refrigerant leak that would be expensive to fix, and even suggested a repair method that wasn’t ideal for our heat pump in the long run. When Bryson from this company came to check it out, he found there was actually no leak at all. He diagnosed and fixed the real issue right during the initial visit, with no extra charges. Bryson really understood heat pump problems and explained everything clearly. When it came time to move our HVAC system and install a new register, Preston and Trenton were the technicians who came out. You could tell they had a lot of experience—they worked efficiently and kept everything tidy. Now our basement ceiling space feels much more open with the HVAC unit relocated. We’re really happy with how everything turned out and have peace of mind knowing the job was done right. If you’re in Fullerton and need heater repair or HVAC service, this is the team to call!

After having three different companies come out to look at our furnace replacement, I decided to go with Tria Air Conditioning Pros. Greyson was very straightforward and professional—he listened to what I wanted and made it clear they could handle the job, which gave me confidence. The price was better than the other quotes I received, and I liked that they work with Lennox systems, which is what I wanted for my home. On installation day, Shaun and his partner showed up right on time. They were polite, worked efficiently, and made sure to clean up everything before leaving. The whole process went smoothly from start to finish, and now my house feels much more comfortable without any issues. I’m happy with the service and will definitely call them again for any furnace or AC needs. Highly recommended!

I’ve relied on Tria Air Conditioning Pros for furnace repair and maintenance ever since I moved into my house. They always do an excellent job checking and fixing my furnace, and when it needed to be replaced, they handled everything smoothly. Thanks to their regular maintenance, my old furnace lasted much longer than expected. When it was time for a new furnace and central air system, they gave me the best price out of three different quotes. Bryson explained all the options from top brands, answered my questions, and helped me pick the right one. The new system runs quietly and works great. They even registered my unit and offered a free follow-up check to make sure everything stays in good shape. In my opinion, they are a top-quality local company for furnace services. Give them a try—I think you’ll be very happy.

After my usual furnace repair company closed, i was unsure who to call when my system suddenly stopped working. Tria Air conditioning Pros sent greyson right away, and he was friendly, professional, and really knew his stuff. He figured out what was wrong with my furnace quickly and ordered the parts that were still under warranty. As soon as the parts got in, he came back to do the installation fast, without any delay. Since then, i’ve gotten a couple of follow-up messages just to make sure my furnace is running smooth. now my home is comfortable again and i feel good knowing if i have any more issues, help will be there quickly.

After buying an older home in Fullerton that needed a lot of updates, we have worked with several contractors over time. Out of all of them, this heater repair company stands out as the best for professionalism and quality work. Last year, they installed a new heating system for us at a fair price, and just this week, they came back to clean our ductwork and perform the annual heater maintenance. The office staff explained all the charges ahead of time, so there were no surprises. The technician, Bryson, was friendly, knowledgeable, and explained every step of the repair and maintenance process. He also made sure everything was tidy before he left. As someone who used to run a small business, I can tell that the management here really encourages their team to take pride in their work. I would highly recommend their heater repair services to anyone in Fullerton.

Shaun came out in the morning to check my heater, gave me a clear estimate for repairing it, and explained everything in simple terms. After I agreed to the quote, I asked about the installation timeline, and he let me know they could come back after lunch and have everything finished by the afternoon. They even installed a new thermostat and made sure the heater was running well before leaving. The team was right on time, polite, and really knew what they were doing. They also made sure to clean up the area before leaving. I’ll definitely call Tria Air Conditioning Pros again for any future heater repairs or maintenance in Fullerton!

when my heater stopped working, i first tried to get it repaired through my home warranty company, but after a couple of weeks and another company’s visit, it still wasn’t heating my home the way it should. i realized it was time to look into replacing my old units. a friend recommended i get a quote from a local company and mentioned i shouldn’t bother with several other places. i got a few quotes and found that this company offered the best price for the heater brand i wanted. one of the other companies said they’d quote the same brand, but then only offered a different one and didn’t mention it until later, which didn’t feel right to me. shaun, the project manager, and the rest of the installation team did a great job from beginning to end. they explained everything clearly, kept me updated, and let me know about some helpful local rebate programs i didn’t know existed, which made things even easier. they were always on time, professional, and quick to address any questions or feedback i had. i’ve worked with a lot of contractors before, and this was by far one of the best experiences. if you need your heater repaired or replaced, i would definitely recommend this company!

We recently needed to have our air conditioning system replaced, so we reached out to several companies for quotes. This company really stood out by giving us a fair and quick estimate. Preston took the time to explain the whole AC replacement process in simple terms and made sure we understood exactly what was included in the contract. Their warranties are excellent, and the team showed great professionalism from start to finish. The installation crew, Trenton and Bryson, were friendly and paid attention to every detail, making sure the job was done right. If you need AC repair or a full system replacement, I highly recommend this company. They also handle appliance repair, plumbing, and dryer vent cleaning. With decades of experience, they always deliver top-quality work. Definitely a 5-star experience!

I am very pleased with the service I received from this HVAC company! Preston and the installation team arrived right on schedule and did a fantastic job putting in my new Lennox Mini Split system. Their attention to detail really stood out—they made sure everything was set up perfectly, and they didn't leave a single bit of mess behind. After the install, Preston took extra time to show me how to use the system and explained the remote controls clearly. I’m also happy with the regular maintenance they provide for my geothermal system, which keeps everything running smoothly and efficiently, especially during our hot California summers. Overall, the quality of both the equipment and the service has been excellent. I highly recommend this company for anyone looking for reliable HVAC installation and maintenance!
