They have been around for many, many years. They are very knowledgeable and it is pleasant to have them come into my home. They have been very reliable. They always come out quickly when I have a problem. I have a service contract with Environmental Systems and I pay them on a yearly basis.

I know them for a long time. I can always rely on them. They come and change the filters. They take care of all things. I called them once to check on some vibration in the heating and they came and inspected it thoroughly. They informed that it was not a problem, but I could get it fixed which would be expensive. They give tips and suggestions.
Description of Work: I use them to service the heating in my house.

I have had ESA service my heating system for over 25 years and, frankly, was surprised they weren't already on Angie's List. Every person I have dealt with has been courteous, knowledgeable and the techs are always timely -- or call to say they are running late. About 4 years ago, I had them install a complete new HVAC system. They carted the outside unit very carefully down the hill and into the small, tight space available to it in my backyard. I will continue to make them my #1 choice for all my HVAC needs.
Description of Work: Annual maintenance check of my heat pump and humidifier units.

We called them in the morning and they were able to send someone out be fore noon that day. The water pump was working at that point, but was making an awful noise. They did not push me to replace it, however, I wanted the problem fixed now, rather than waiting until the pump failed completely. We have a service contract with them, so we received a 10% discount for the parts and labor. All in all, the provided prompt,efficient, reasonably priced service.
Description of Work: We have used Environmental Systems many times over the years (they also installed our Heating/AC system about 10 years ago). This time we called them after our A/C stopped working while we were on vacation. They diagnosed the problem and installed a new water pump (for the A/C condensation).

They were great. They explained everything really well. I got the estimate very quickly. They were wonderful and they were really careful about the installation. They came out on time. They took less time than I thought they would. They went above my expectations and they really knew what they were doing. I was very happy with their service.
Description of Work: They replaced my heat pump and air conditioning pump, inside and out in a two and a half ton system. They used the new environmentally safe coolant.

We have an old home and when Mike came in to give me an estimate, he was very confident that his crew could get the job done without too much trouble. The other estimator from another company kinda freaked out, and really didn't know how to get the thing replaced. It took them less than a day, without too much trouble.

As far as their rates go, it really depends on what type of air conditioning system you have. I pay a basic fee for a seasonal check once every year. I have used this company before and I like the service that they provide.

I had 3 bids and theirs was the lowest, they were the most competent and most efficient. The heating, A/C unit is in the outer wall and was originally a different size and therefore required a brick mason to cut a hole for the new system to fit. This company was able to hire this work out without me having to do it. They finished it within 1 day where another company was going to take 3.

Mike Hendricks was very responsive in proposing several system options to us and advising us on their pros and cons. Once we decided on a system, he ordered the parts and scheduled his team to do the install. It was several weeks before they could get to us. However, on the scheduled day, their team showed up on time and did an excellent job of installing and testing the new system. The team leader was exceptionally good, both at managing the project and explaining to me how the system worked. He took a lot of time to go over the system with me and demonstrate how to program and use the thermostat. They also did an excellent job of cleaning up when they were done. The price was not the cheapest around, but the excellent service more than made up for it.
Description of Work: Replaced old gas furnace and central air conditioner with a new high-efficiency system. Included replacing outside and inside furnace and A/C components, running new flue piping, installing new humidifier and thermostat, hauling away old system, and cleaning up.
