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....

Amy M.

We had Donahue’s clean our out vents and they did a fantastic job. Hunter, Tyler, Zack, and Kyle were all very respectful and were happy to answer any questions we had. I would strongly recommend using Donahue’s Heating & Cooling for your needs.

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...

My in-laws were having low air flow with their central air conditioning system and called Donahues to address it. They were immediately put on a wait list, but were seen the next day! Dan came out and did a thorough inspection inside, changed the filter, and then thoroughly checked the...

Called to have service as my HVAC Unit wasn’t blowing cold this spring. They got me an appt for 2 days later, and called me a day earlier to let me know a tech was available. It worked for me so Zach came out and replaced a capacitor on my...
