About Us

Quality service since 1962! Regis F. Donahue founded Donahue’s Heating & Cooling in 1962. The business started out of his home with one service truck. He grew it to its current location. After working side by side for years, his son, Regis J. Donahue took control of the business in 1995. The third generation has been actively involved for several years and the full transition started in 2017. David Donahue is grateful for the opportunity to continue the family business, proud of the history of Donahue’s and excited for the future.

First time dealing with Donahue. We received a quote from Mark the same day he came to look at the job (amazing). After meeting with the other companies we contacted, we decided to go with Donahue’s. From estimates to office calls/visit, to the installation crew, we could not have been...

We could not be happier with the central A/C job that was done in our over 100 year old home. We were so worried about losing valuable space that we held off exploring this. Now we are asking ourselves why we didn’t do it sooner! The whole experience was professional....

We switched to electric heat in 2022 from oil. A new variable speed air handler was installed by a different vendor, using the 3 zone control system that this vendor had installed in 2004. However, the original zoning controller was not capable of optimally using the capability of the new...
