Multiple Positive Experiences

I have used these folks several times. They always tried to service my old unit rather than sell me on a new one \- and they did so at reasonable rates. Recently, I made the decision to be proactive and replace the 20 yr old system before it needed more repairs. The guys did a great job, were professional, available to answer questions and responsive to any concerns

Mr. Fix It (Mr. Cool) was great to deal with over the phone and even better in person. They arrived on time, cut new airflow areas and installed vents, and the installation of the indoor unit is almost "beautiful".

This is the second time I have gone with this deal and once again he did a great job. My air conditioner failed and did the checkup and replaced the unit within around two days (pretty quick given it's summer time). If my other AC goes on me I'll be giving Mr Cool a call.

Oustanding Planning and Installation
March 30, 2018
Brian, the Owner of Mr. Fix It and Mr. Cool Air Conditioning oversaw the installation of a new Carrier Infinity System from start to finish. Then he returned after the installation for a final inspection and to tune up a few minor items like the thermostat setting. This project was very well planned from the beginning and I was made familiar with all of the equipment that was to be installed. Mr. Cool ordered, ahead of time, all ductwork, plenum material, vents, supports, gas line, drain pan, float valve, thermostat, insulation and more and it was all delivered to my house on installation day. This enabled the removal of old equipment and installation of new equipment to proceed smoothly without interruption. There were no surprises. The old ductwork was inspected prior to the job and the necessary changes in ductwork size, air returns, and vents was made to enable the Infinity System to breathe freely and to perform to specifications. The installation of the 4 ton unit and the heater and related plenums and ductwork modifications was done in a workmanlike manner and the unit looks very good in its location in my attic. The installation is superior to what was there before. The compressor unit outside on the concrete pad was also installed in a clean and organized manner. New cabling, line insulation, switch box and other items were used. An important detail was to replace my 22 year old circuit breakers on the main power panel with fresh breakers. The startup of the Infinity System went flawlessly. I had to learn the new thermostat, but that proved to be easy. I was glad I took Brian's advice and replaced the old, plastic ceiling vents. Some of them were in raunchy condition. The new steel vents work better and look much better. The system is running whisper quiet so far but we are in the Spring season. The 100 degree weather lies ahead of us. I will look forward to Mr. Cool providing long term routine maintenance on this new system. Based on how well he maintained the old system, I look forward to years of trouble free HVAC.

We had a great experience with Mr. Cool! He was very attentive to our HVAC needs. We had spray foam installation and had humidity concerns. He was very knowledgeable and found a great product solution for us. Our ducts were not up to code and he solved this issue in the attic of our very small house. The installation team was very professional and kind to our young family. They were careful with equipment on our wood floors and house was left clean. We would definitely recommend him to our friends!

Complicated Install

I had unique requirements and it was solved with a 3 zone system. A lot of effort was made by the installer to make sure and take care of all of my concerns.
