They were very friendly and customer oriented. The only negative thing I would say is the clean up in my house was a little less desirable. They didn't come with there own cleaning equipment so they asked to use my broom. Unfortunately, the mess required a vaccum. I ended up having to clean up after them.

Very professional workers and owner. Work performed as stated in the time stated. Cleanup was professional. City inspector had some issued that were addressed without delay and then approved. I would definitely recommend to other and would use them again for another project.

I've done lots of comparison shopping and the value at DeMonia's is amazing. The company's furnace was of great quality and whenever you call the company, you actually speak with a real person. Super quality, service, installation. Everything.

After a couple estimates from other contractors we chose to go with Demonia's. They gave us a better price and a better unit than the others. they started the job the next day and finished it the same day. They installed our Rudd furnace and air condition system correctly even added another cold air return to help the perfomance. We're happy with the job you can hardly even hear the furnace running and the house is nice and warm. Thanks for the good job.
