Thanks to Devon and the whole crew at Greiber Heating. We were in a bit of a crisis having our air conditioning go out in the middle of a very hot week. Devon responded quickly and efficiently with a complete new AC and furnace. We have used Greiber exclusively in two homes over the past 30 years. They are honest, efficient, and pleasant to work with. We believe they have treated us fairly with all work done in our home. Thank you again. Brian G.

Everyone at Greiber Heating and Sheet Metal was prompt, responsive, knowledgeable, and respectful. They made the experience of needing a new furnace unexpectedly much less stressful than it could have been. Even though the cost of a new furnace is substantial, we were also surprised at the quality of furnace we got for what we considered a fairly reasonable price.

Top marks for Greiber Heating \& Sheet Metal, who just replaced our old furnace and air conditioner. The installation went smoothly—the techs really knew their stuff. They were meticulous in their work and left the work area cleaner than when they arrived! We got a thorough walk\-through of the new system when they finished, followed by extensive hands\-on training on the new thermostat. We are completely satisfied with our new system and the work done and highly recommend Greiber Heating \& Sheet Metal if you are looking for a new system.

Greiber did an outstanding job, with prompt service, careful installation, attention to back entry and masking due to Covid 19, explaining the system, returning to fix noise in damper, and spotless clean up. I was disappointed that the repair of the noisy damper was not listed on the warranty, therefore, I will be billed for that part, even though it is a vital part of the operation of the furnace, and should be covered, as all the other vital parts are.

Devon Grieber is a Carrier expert and also a professional sheet metal craftsman. When we replaced our old 2000 Infinity with the improved 2018 Infinity Greiber Heating handled the job efficiently in less than a day. The job site was clean and orderly, with several improvements to the overall furnace area. The new WI\-FI control system was easy to adjust to with Devon's demonstration and training. I can control the entire system from my iPhone.

old air conditioner (a different brand)has been hanging on for the last couple of years given the age decided it was time to replace before it died completely. The new carrier was highly recommended. old furnace (a different brand) was still working but not efficiently also given the age decided to replace at the same time so both new units were installed in one day and are compatible and more efficient

We had Greiber H\&SM install the top of the Carrier line gas furnace and air conditioner. The install replaced the orginal Carrier furnace and AC unit when we built our house in 1995. Carrier provided us a great HVAC system and the replacement keeps the our home very comfortable. The system is very quiet. Great working with Greiber all these years. I highly recommend Carrier and Greiber H\&SM.
