"We had a wonderful experience with Comfort Energy! The service person, whose name was Chance, did a thorough evaluation of the problem with a focus on saving us as much money as possible, to either repair or replace our 30-year-old heat furnace. He quickly determined that our inlet filter was too dense (it was a Merv 11 and should have been a Merv 8) and that that was probably causing the heater to go off an on every 5-10 minutes. He then tested and confirmed his hypothesis. He also performed a CO test to make sure there wasn't anything more serious going on. Finally, he gave us a good idea of replacement options, which we should probably do before the next Winter, but not necessarily right away. All in all, this is exactly the kind of assessment we needed, and it cost orders of magnitude less than what was estimated by the first service company we had come out. Chance was great, and Comfort Energy is our go-to for heating and cooling service and/or installation from now on."

"Great Job! They made it quick and easy to have HEAT back in my home! Thank you Rudy!!"

"Duke did a great job at a fair price. We needed AC and decided to replace our old furnace at the same time. In addition Duke wrapped with insulating bubble wrap our old ducts that were exposed. He tied the drip line into our existing downspout in a neat fashion. I'd highly recommend him (he's a fellow submarine vet too!!)."

"I recently had a new HVAC system installed by Aireserv, and I couldn't be more pleased with the results. From the beginning, the team was professional, courteous, and informative. They arrived on time and were very thorough in explaining the detailed installation plan, the features of the new system, and how to operate it. The installation went smoothly, and the technicians cleaned the area while working. Once the system was installed, they ran tests to ensure everything was working perfectly and took the time to answer all of my questions. The new HVAC system has been a game-changer in terms of performance. It heats and cools my home more efficiently than my previous unit, and I've noticed a significant improvement in comfort and air quality. The system runs quietly and maintains an even temperature throughout my home. I also appreciate the energy savings I'm already seeing. My energy bills have been noticeably lower, which I can directly attribute to the new system's efficiency. Overall, I'm delighted with the service from Aireserv and the performance of the HVAC system. I highly recommend them to anyone in need of HVAC installation or upgrades. They provided excellent service from start to finish! A BIG THANK YOU TO ALTON THOMPSON AND HIS TEAM FROM AIRESERV."

"Rittinger responded quickly. Alan, the tradesman they sent over was professional and quick. I hired them to install a clothes dryer vent and to open up a vent in my garage for the hot water heater. The work was high quality and installation was clean."

"Air Sharks LLC recently replaced our residential Natural Gas NG HVAC (otherwise known as Furnace / Air Conditioner) with an electrical Heat Pump HVAC HPHVAC. I MUST COMMEND THIS COMPANY IN MANY WAYS: (1) outstanding installation workmanship & craftsmanship, (2) excellence in Building Permit application & follow-through, (3) excellent follow-through with respect to Rebates from application through all administration steps, and (4) excellence in application and follow through with various agency regulations. Air Sharks Administrative Staff has built a company that covers ALL aspects of large Home Projects. I strongly recommend them!"

"I had a burned out fixture, a motion-sensed CircLine florescent light which stopped lighting. From past experience I thought the problem might be the ballast as well as the bulbs. I had ordered and had the replacement bulbs and the ballast when I had fixed the light myself, two years ago. The fixture is in a really difficult location for me, so I used HomeAdvisor and was referred to Pacific Coast Electric, Heating and Air. Alfredo understood my problem, and luckily only the bulbs needed replacing. However, he rewired the fixture to the wall, commenting that a slightly loose wire connection could have accelerated the bulb burnout problem. He tested the ballast voltages which were good. Total repair took less than an hour and I only had to pay the minimum time fee. He recommended that the fixture be replaced with an LED light fixture when it went out next. The LED lights should last 10 years rather than the 2 years we have been experiencing."
