I used Can-Cool Heating and Air 3 years in a row. I had an older townhouse with the original air conditioner and it went out. I called several companies to give me quotes and Can-Cool's was the second lowest, but Carl (the owner) seemed to be the most honest. The other companies told me I needed to replace my coils, too, but Carl told me not to replace them until they actually went bad because I could possibly go another year or two without replacing them. I went a year with the old coils and then called Can-Cool the following year to come out and replace the coils. Can-Cools prices are very reasonable and Carl is always honest and super friendly!
