Customer Testimonials


“Justin and Terry were very professional throughout the whole installation of our whole home dehumidifier. They were punctual, very careful on not tracking mud into our home, made sure we knew who they were, what they were doing, if we were comfortable with/without masks and made sure we were okay with the overall setup before they began. They were courteous during the installation, thoroughly explained the system, answered every question we had, cleaned up well and made sure we were comfortable and happy with everything before leaving. We had an overall very good experience, as always with ESI. Thank you Justin, Terry, and Nick on a job well done :)”

“The guys were prompt to show up, did a great job on the install, cleaned up after themselves, were happy to answer questions and knew what they were doing. We were very pleased!”

- Robert W.

“I was very happy with Justin and Terry. They were both very polite, knowledgeable, and eager to answer any questions I might have. When they left my home, they had cleaned up and you wouldn’t have known that they were ever here. Being in the construction trades myself, and what I expect from my guys who go into a person’s home representing our company, to find a company like ESI is a real pleasure to deal with. I will be highly recommending ESI Heating and Cooling to all my friends and people I deal with. Thank you ESI Heating and Cooling. “

“As part of the excellent installation process for our new Tempstar furnace, Steve came back to our home a week later to conduct a thorough “tuning” and check of the furnace. He also reinforced the training we had received from Justin and Terry on basic maintenance and operation of the thermostat. Steve was prompt, friendly, and went straight to work. It was obvious that his goal was to make sure all was well with the new furnace and to make sure that we were comfortable with operating the thermostat. ESI has a wonderful team. We are completely satisfied and grateful!!”

“Mike showed us during fall maintenance that a problem was developing with our 17 year old furnace. Nick provided a couple of quotes from the Tempstar furnace line, assuring us that we would notice improved performance and better thermostat control. He was so very right! Our home temperatures are much more even between rooms and between floors. Even the humidity feels more comfortable. Our old thermostats were so difficult to operate and modify. This new one is intuitive and a breeze to use.
Justin and Terry arrived as planned, were friendly, considerate and helpful. They had the new furnace operating the first day with no noticeable discomfort during the install despite the winter weather. The next day they returned to finish the job and train us on the thermostat controls and basics like changing the filter.
We couldn’t ask for a smoother transition and are very pleased with our new furnace. Every chance we get we recommend the team at ESI — maybe we shouldn’t, they’ll get too busy.
Thanks!”
