I sent out a e-mail inquiry. Demonia's Heating & Cooling got back with me the next day by phone. I explained to him what I had and what I needed and was given a very reasonable price. I hired him and we set up a date that was soon and accomodated me. They arrived at a reasonable time and went above what I expected at first. They did not think that they were going to get the furnace running that day untill a 3rd guy came over and discovered that the used furnace that i had bought on my own was wired incorrectly. They not only got it running but they also had to install at a small added fee an electrical line to my fuse box. I would rec. them.

DeMonia's really went above and beyond to make sure my home is comfortable and safe, at a very reasonable price. They were on time, professional, and knowledgeable. I highly recommend them!

We contracted DeMonia's last year when we were having AC problems. When we started having problems again this year, they were the first call we made. They came to repair an item that was still under warranty...the part failed again...not because of them. It was the third time in three years that the same part failed - it didn't matter who repaired it because it went each year. It was something else in our system causing this one part to continually fail. So, that coupled with a leak in our coil, we decided to get a new Central AC system. They were quick to schedule the replacement and quick to replace it and reasonably priced. 5 stars!

They did an excellent job, in by 9:00 and was done by 4:00. Cleaned everything up. Was the cheapest by far compared to other companies. When I called Bill DeMonia, he came over that evening and knew exactly what I was talking about and what needed to be done. Offered a larger unit for our house and blower motor for the furnace. Thanks for everything. Have recommended to our neighbor and they used him also.

All work was done in a timely and professional manner. One issue is still being worked out and were still in contact trying to resolve.
