My father has used Donahue’s for many, many years. He does not do anything online so I am writing a short review for him. When furnace failed this winter and needed to be replaced, they were there! And very timely. Bill was extremely professional with the installation. Very pleased. Thank you!

Bryan Reisz was punctual, professional, and communicated what he was doing in a way us lay people can understand. He wore a mask and cleaned up his work space. It was a pleasure having him complete our routine maintenance check up on our Donahue boiler system. We highly recommend Bryan Reisz!!

I couldn’t ask for a better professional team of Bill and Levi. Called before they arrived so I knew they were on their way, friendly with a positive and professional attitude. All questions were answered and a font of information given. I would highly recommend Donahue Heating and Air Conditioning. Service was 100% from the time I first called them until the time the service was finish. Cleaned up well and placed covering on floor with covers also over their shoes. I can’t say enough of how pleased and confident I am that I chosen them. A+++++

The Donahue Service Technician, Rod D., was timely, professional and thorough when it came to performing preseason maintenance on our furnace. He was clean and tidy which is important to us as well.
Also, kudos to the gal answering the phone at the office. She was very knowledgeable and helpful and made sure the proper UV light and humidifier filter was available to bring to our house.
I feel good about calling Donahue's and the interaction we've had with their personnel. I feel confident they will be our choice going forward when it comes to service on our Furnace/AC.

So far not impressed at all with this company. agree that the customer service people are nice. But they have a manager Pete who is a bit too snarky for our liking.
And they absolutely did NOT fix the problem the first time.

Just had our annual furnace check done by Mel of Donahue's. An exceptional company! The technicians are professional, knowledgeable, thorough and always take the time to listen and followup on every concern. Mel was certainly no exception! She did an outstanding job of cleaning, setting up our humidifier and thoroughly checking the furnace equipment. She even made a recommendation for when we have our air conditioner checkup. Donahue's installed out new air conditioning unit and our furnace last year. We are extremely satisfied and following up with our annual furnace check is simply

I recently purchased a new much older home. The boiler is ancient and I really needed someone to get it up and running, make sure things were working properly, and to explain how to use it! When Mel showed up she was awesome very knowledgeable and super kind. She didn't try to scare me into anything I didn't need. Flat rate! I love the coupons on… the site (for a single mom on a budget I was excited about the price)!! They got me a fast appointment. I have been dealing with a ton of contractors and repair places for other things and it's been a nightmare. I'm truly glad I found you guys

I've worked at Donahue's for a year and a half as my first serious job out of high school, and they've been an extremely impressive employer. I feel like I'm at home there, and my coworkers feel like family. If you're looking for work in HVAC, this is a fantastic place to start.

Recently we were having some issues with our central air unit. I wasn't really sure who to call, but after reading such good reviews, I decided on Donahue's Heating & Cooling. I am so glad I decided to go with them. We were able to get an appointment right away (within 1 day), and the technician who came to our house was friendly, and definitely knew his stuff. He was able to fix our problem and it was at a very fair price. I will continue to use Donahue's in the future!

Had problem with AC in the evening. Called Donahue's and within an hour technician was here. Made a temporary fix so AC would work until
they could get part needed to make the permanent repair. Would highly recommend them!

What excellent service from my recent furnace tuneup. Rod was one of the best technicians I have met. Our CARRIER FURNACE is 22 years old and working beautifully. He needed a part and they delivered it within 15 minutes!! We are so appreciative of his knowledge and honesty. Thumbs up all the way!
