Jim was at my house in 30 minutes after my call. Very knowledgeable, totally professional, and resolved my problem immediately. Even made two additional checks to insure my system was up and running correctly. No question who I’d call if I ever have HVAC problems in the future.
Would recommend their service.

The Grenz team of technicians installed my new AC unit. The service technician was very professional, courteous and trustworthy. I would highly recommend Grenz for your HVAC.
With a ton of other jobs to go to, we were given priority and had our issue dealt with in an efficient and timely manner.
Installed my new furnace and air conditioner 2 years ago and they did a great job. We now just have it checked every couple of years. Jim checked every thing out and they are working well. I'll see Jim again in a couple of years.
Service was fast and efficient.
On time , very experienced, very informative, very pleasant. I would recommend them for your fireplace service.
