They provided us with comprehensive service from start to finish in their installation of a new high efficiency central air conditioner. Mike was very informative and provided full service from obtaining the permit, registering the warranty, and applying for our Ameren rebate. The installers were polite and very professional, including leaving the worksite totally cleaned up.

Installation was smooth and reasonably quick. One loose wire problem to the thermostat which was found quickly. Had to add freon to the unit but this was determined in the initial testing.

Installed Carrier compressor unit on my home A/C system
May 06, 2018
Ralph and his son, from a Reliable Heating and Cooling, did great job of replacing the compressor unit on my home A/C system. They were very nice, and very professional. They even came on a rainy day and put up a tent over the work area to perform the installation. This was my first time using this company and I couldn't be more satisfied. I recommend them highly. They also were considerably less expensive ($437 less) than a larger, competing company whom I had used for years. Vann C.

A/C went down. Service Rep came next day to service \- A/C needed replacing (we already felt this was going to be the case) \- they gave me estimate same day, we agreed to a system we wanted and they were flexible with the install date we needed. Installers arrived on time when scheduled and completed same day. All went smooth and everyone we dealt with was friendly, helpful and professional.
