Our furnace kept blowing cold air. I made an appointment after reading recommendations on Nextdoor forum and the reviews on internet are nothing but good. I was able to get an appointment on the same day and the technician knows what he is doing. In less than 30 minutes, he fixed the problem and tested it to make sure the issue was resolved. The charge is reasonable as well. Highly recommend this company.

I reached out to Dayco after reading all of the positive comments on our neighborhood FB page when our furnace went out. They gave me a quote quickly. The price and quality of their furnace was better than several other companies, including current maintenance company. Dayco was able to install the furnace quickly as well. The technicians were very polite and clean. My neighbors were right; Dayco is the best local and honest company with competitive prices.

The office was very understanding of my issue and had someone out later that day for an estimate. Better yet they were able to get a crew out the next day to fix the issues I had from a previous contractor. The guys were friendly, courteous and professional and rectified the problem.


Shaun was nice enough to come out right before the holidays to give me a quote. The installation went very well. Quicker than I expected. Jason, the installer, was really nice and kept me informed during the whole process; great customer service. Great experience so far. I would definitely recommend.

Dayco is very reliable. When you set your appointment with them they call before coming and always on time. They take care of you in a very professional manner. I would recommend them to all of my friends.
