"My experience was fine. I went with this company instead of another company because of the reviews I read on Angie's List. It took them about a half a day to install the air conditioning unit. I think it was 3 workers that came out."

"Sean was great during his visit to fix our furnace. He met us right away on a weekend, knew exactly what was wrong and repaired it for a very reasonable price. He was so good we asked him on the spot to do our twice a year furnace/AC checkups. Can’t recommend him highly enough."

"I had the best experience with Hecomo Heating & Cooling. My house's AC/heating system stopped working all of the sudden and the temperatures at the time were 90 degrees and up. I was desperate looking into many different companies. Many of them, came over to my house and did estimates at ridiculously high prices. Luckily, I found Hecomo. They came to my house, did an estimate and were ready to install my AC/heating unit very quickly and at a good price. Also, the customer service was great. They were there for me throughout the whole process. They explained to me everything that I needed to know about the system and the features. Everything is very modern and updated. I am very happy I found Hecomo."

"Great! He provided additional information, suggesting I install a UV Light Air Purifier to my HVAC system. Which would help eliminate the possibility of mold growing in my vents."

"Of the five bids I received, Michael Bonsby Heating & AC company proposed the best value for the price. From start to finish, through removal of the old furnace to installation & operation of the new furnace, the service technician was knowledgable & experienced in doing the work, and helpful in answering questions and explaining the use and operation of the new furnace. The office staff was also responsive and courteous whenever I called with questions or scheduling of installation. I'm very satisfied with this company and recommend them highly."

"Patrick came out the same day I called him, even though it was a Saturday. He was attentive to the problem and all the details I provided, as well as thorough, efficient, and charged very fairly. I was sure my hvac needed replacement, but after a few quick measures and parts replacements, he got the job done in several hours and the house feels satisfyingly cool again! Highly recommend!"
