I highly recommend this company and their staff. When our AC went out I had called 3 places to get quotes. Of the 3 places H. J. Faust was the best all around. Lori came out and thoroughly went through all of our options. She was very friendly and professional. The day we had the unit installed Griffin and Colin where the techs that came to our home. These to young men were so courteous and professional it amazed me. If I owned a company I would want my employees to be just like them.

They have very professional employees. Lori was able to come to our home quickly to give us a quote for a new A/C. We were able to get an install appointment a week later, which is sooner than what we were expecting. Will and Colin removed our old unit and installed our new A/C. They were all friendly, professional and informative. We have also had Jake at our home to service our furnace and he has the same characteristics of the ones I already listed. Thanks so much for a great experience!

Wonderful service! Our 28 year old furnace went out in the middle of the night Thursday, they were out here mid-day Friday and determined that the cost to see if it could be fixed (hey, 28 years old, remember) would likely be prohibitive, had an advisor out a half hour later, and a new furnace in the the next day. Jake as the original tech, Lori as the advisor, and Roman and Riley as the install team were all everything we could hope for!

On time, professional, took care to explain all options and ensure we were comfortable with our choices. We WILL be calling to replace the 28 year old AC unit this spring! (Don't blame us: we just moved here, and these came with the house!) March 2022 - well, they were so great the first time, we had them back again to replace our a/c and add a whole house humidifier. Chris P. and Griffin did a wonderful job for us, just as the previous crew did, and we are still extremely satisfied with this company and all of the service they have provided!

Chris P. installed a new central A/C unit. He was very professional and I received a reminder text the day before the install, and another text the morning of, letting me know who would be coming and at what time. He and his assistant were super efficient and Chris went over everything with me afterward. I really appreciated him taking the time to answer all of my questions. I am very satisfied with H.J. Faust and their employees and highly recommend them!
