Reviews

Purchased a new air conditioner and furnace and was impressed from the initial sales contact, to verifying what we needed, installation and clean up. Everyone we dealt with did a great job and we love our new system.

I could not be happier with my decision to use Welsch.

Jeff C.

We have used Welsch for over 30 years and have never had any problems. I recommend them highly. Very fair, prompt, friendly people and competitively priced.

Welsch Heating and Cooling has always been a great company for my family’s HVAC needs. Pure professionals!

JDO

Welsch Heating and Cooling came out fast (our old unit stopped on a Friday – our new one was in by Monday.) They were very responsive to our needs and very helpful during the installation and followed up to ensure we were happy with our service!
