1st off, I have to apologize for taking so long to to write this review. I've been really enjoying my new heater. Cool Air Technologies installed a new heater and air conditioner in my home last month and they did an amazing job. The crew showed up on time and removed the old heater, installed the new heater, air conditioner and all new ducting in one day with two people, it was estimated as a two day job. They were incredible. Friendly, courteous and hard working. I would STRONGLY recommend this company for any HVAC work. Thanks to Bill, Trish and all the crew.

Great quick service. Called for a not working heater at my elder dad's house and Bill returned my call (a biggy) and had it fixed in a day. The quick response and fast fix was priceless. Highly recommend and would use again. Service: Repair HVAC

Contacted Bill for a 2d opinion on an expensive Furnace Repair. Bill responded on same day and determined that repair was over priced. Recommended a complete replacement of furnace and AC at nearly same cost of original estimate. Crew was on time at 8am, professional, cleaned up and gone by 2pm. Best thing about Cool Air is NO creative selling. Service you can trust!

I have known Bill for 18 years and he is simply the most professional and knowledgeable HVAC contractor in the business! Bill has done work for us over the years and today he worked on Our sons first home. Bill is a "throwback " to what contractors used to be- NO BS and he will tell you what is wrong with your system and how To fix it, but he won't try to sell you something you don't need! If you are looking for an HVAC contractor- call Bill and you will never use another contractor again!
