Marilyn Reemer

Greg came out same day that I called, was very knowledgeable and professional. He diagnosed the problem with my furnace, and had it back up and running in a very short time. Very fair-priced. Would highly recommend.

Mark Silver

Greg came out to give me an estimate for my furnace the day I called. While other companies wanted to charge me several thousand for a complete replacement, Greg was able to fix it for just a few hundred. An option other contractors didn't want to give me. Appreciate the honesty and the prompt service. Highly recommend Greg.

Greg came out immediately on a Saturday. He diagnosed the problem as a new furnace being needed a mine was about 40 years old. He returned on Monday morning, installed my new furnace. Greg was very professional and honest during the process. I would highly recommend his service.

Matt Peak

Greg has saved me while I was in a pinch multiple times with both my ac unit and furnace. He just got done installing a new AC unit and the work was exceptional! Ive been having a problem with my furnace not keeping up to temp for quite some time now as well and he was able to quickly fix the problem. I couldn’t recommend Greg enough, honest man who does honest work!
