I can't say enough positive things about DeMonia's Heating and Cooling. Prompt, professional, knowledgable, explained everything from the pricing to maintaining my furnace. My 95% efficient furnace was very affordable, the men (Joe and Brandon) that installed it were on time, efficient, had it installed in the amount of time and that they said they would. Explained how the new furnace worked (what the lights meant on the electronic panel) right down to the filter size. I would especially recommend DeMonia's to any single woman that owns a home. No worries about being ripped off by high pressure sales people.

Bill and his team were great. Very reasonable price, good product and excellent follow through. Others seemed to complicate the process with too much analysis and technical speak. Bill was a straight shooter and delivered all they suggested.

Bottom line is that DeMonia's Heating & Cooling was most helpful in upgrading an old worn out home HVAC system to a modern forced air 95% efficient system. And WOW what a difference. Installers were on time and cleaned up everything at the end of the job. Everything was expertly installed as agreed and on budget. Before the installers left, they insured I knew how to operate and maintain the newly installed a/c unit, furnace, humidifier and hepa filter. I wasn't someone taken for granted but treated like a valued customer whom they were willing to go the extra mile in completing the job in a single day. Highly recommend!!!!!!!

DeMonia's gave us a fair price which obviously was the determining factor in choosing them as our contractor. The reviews on Service Magic were also very helpful in making our choice. The installation was prompt and went smoothly. The only thing I would suggest, is that when making your proposal, you give more information to your customer about the air conditioner you are installing along with warranties and the service record of the unit. I realize you work with this on a daily basis and it may seem pretty basic knowledge, but to us as the customer we know little to nothing about air conditioners!

Bill came when he said that he would, He came exactly in on budget (while being the lowest estimate) the the exact penny while actually adding a pump so that there would not be drain hoses on my floor. He moved the furnace to a more convienent spot in my basement. Took out all of the duct work and put it all in the floor joist and finished when he said he would. His crew was extremely polite, completely cleaned up the entire mess and made sure that I was satisified before they left. I would highly recommend this company for the professionalism, quality of work, and just doing what they said and when they said. Five stars are not enough.

DeMonia's did an excellent job at installing a central a/c unit that enabled me to keep my existing furnace. They were professional, courteous, on time, and didn't try to upsell me on any unnecessary products.

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.

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.

They where professional and informative. They had the best price around for a top rated furnance and air conditioning units. They where on time finished when they said they would and when we had a slight problem with something that was damaged they where right here making it right by us. If you are considering a new furnance or air unit I would highly recommend you contact Billy.

The workers that came to my house to install my new furnace and AC were very professional and on time. I would definitly recommend them to my family and friends. And from all the estimates I had received from other heating and cooling companies, DeMonia's price couldn't be beat! Thank you guys for making your customers your #1 top priority..

Very nice clean install. Very good techs. I will be certain to use DeMonia's in the future for any HVAC needs I have with other projects. Bill is cool, and they beat other estimates by thousands. I'm very happy with my new furnace and air.
