"I was extremely impressed with the service provided by Air Sharks, who replaced my aging furnace and damaged heat ducts. Elizabeth provided a detailed explanation in a friendly, professional and understandable way. Pricing seemed reasonable, and was 25% below a previous estimate. Daniel and his crew did a fantastic job removing and replacing the new furnace and the duct system in a very tight crawl space. They left the furnace looking absolutely beautiful and clean. I highly recommend them"

"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."

Customers say: Super punctual

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"AirStars Corp was absolutely amazing! They were very professional and really knew what they were doing. They changed the insulation and fixed the pipes, which had been connected wrong before and were starting to leak. Any other company would probably have told me to replace the whole system, but AirStars took the time to do things right. You can tell they care about quality and their customers. I’m so impressed with their work, highly recommend them! "
