Had been looking for a new HVAC professional after the one we had been using retired. I saw several…read morepeople recommended Eco-Cool on another local persons request for HVAC recommendations as well as several other companies. I researched reviews on all and Eco-Cool was my initial top choice after the research. I called the office to schedule a routine servicing of our system on Friday, I spoke with Amy at the office, she offered several options for services including a simple one time service or an annual program. We were able to schedule a tech to come out on Tuesday morning. Our Tech, Craig, was prompt, courteous, and professional even through the multiple questions I asked. He took a look at our system and the area of concern we had and he gave us the news we were anticipating (that our system is running but might not have much time left in it....it's 26years old) he offered to have quote for replacement drawn up if we wanted. (I did) he left us set up for success and he told us his goal was to keep us running into springtime at least....we appreciated that! After he departed, I called Amy again to arrange payment for today. She was kind and professional and let us know she would have a quote to us by the end of the week and even provided insight to what pricing is doing now and anticipated to be after the new year so we could be able to make the decisions best for our family. We appreciated the prompt, professional, expert care we have received in our first few interactions with Eco-Cool and are looking forward to remaining customers for a long time!

Hamilton did an amazing job the first couple of times we called them. We never had concerns about…read moretheir work. In fact, we were so pleased with it that we purchased the service contract. We understood that we were working with a small family-owned company that did not operate 24/7, but after many calls over the course of a year, our calls have not been returned. Therefore, we were not able to use our service contract. Considering the great work they did when they did respond, this has been very disappointing.

we have had this company come out 4 times for the same issue. our AC would randomly start pumping…read moreHOT air. They cleaned the unit, said it was fixed, and it wasn't. They replaced a fuse, said it was fixed, and it wasn't. Beat on the unit, said it was fixed, and it wasn't. Finally come to the conclusion that it was a bad circuit board. The company said they "ordered it", TWO WEEKS later we called them back & are Told they ordered the wrong part. say they will be there the next day with the correct part, never show. Call and get mocked by the person on the phone & treated like a 3 year old but they will "be there tomorrow". Tomorrow comes, no one shows. We were completely ghosted by this company after shelling out hundreds of dollars & over 1k of energy costs for us. DO NOT USE THIS COMPANY. We've already had another company out & the problem completely fixed within 48hrs. told it was a "simple fix". The owner is a rude misogynist with zero accountability.
