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.

The motor for the fan needed to be replaced. He expedited pickup of the new part and just finished up the work. He made sure to squeeze me in because it's getting quite cold.

We've used HGH many times over the years. The most recent was also the most ambitious - converting…read morefrom oil to gas furnace. HGH did not disappoint. From Mark's initial visit to prepare the quote (his was the most thorough of the visits of the 3 quotes we got) to actual installation, it was seemless, very professional, and we couldn't be happier with the result. The price was very competitive also (almost $3000 less than the most expensive quote for the same Rheem system.)

After the initial quote, it was difficult to get a hold of Steve to move forward, and the onboarding process was never completed. A major pain point was the answering service: every time I called to follow up and couldn't reach him directly, I had to re-explain the project from scratch. After several weeks of limited progress and unreturned calls, we ultimately had to go with another provider. It's unfortunate, as the potential is there, but the lack of communication and operational continuity made it impossible to complete the project.
