Disappointing Customer Experience . With great relief I resigned from their services, as lately they've been more often cancelled than actually performed. My last three appointments were rescheduled (in the fall, I was generously offered a fireplace service date six weeks later than originally booked), and today (July 8, 2025) - surprise! - no one showed up at all. Not a word of explanation, no apology, just radio silence. It's heartwarming that they thank me for being a "loyal customer" in their automated emails and text confirmations - unfortunately, all that loyalty has bought me is mounting frustration and lost work hours (I need to take at least four hours off every time they don't show up - which is often). I requested immediately stop charging my Visa for monthly fees and refund the prepaid amount for the upcoming fireplace service - which, statistically speaking, would've likely been cancelled anyway. read more

$76.28 to come to my home to tell me they don't service a Portable A/C, details that was known when the appointment was booked with Dunn Heating. I received a call claiming they were unaware it was a Portable A/C, however every company I reached out to I DID give the brand and model to ensure 1. it could be fixed 2. the repair person had the necessary parts to fix the unit quickly Seems this is more of an issue of faulty in-house communication and I'm charged for their shortcomings - literally, with a threat of going to collections less than a week after I contacted Dunn about the invoice received! $76.28 is very expensive means to be told in person a company doesn't service ANY Portable A/C Units. I would have preferred to be told me over the phone when I could have made other arrangements instead of waiting. Add to this, the invoice wasn't sent until 2 months AFTER the service call. Delay in invoice + threat shortly after contesting the charge ... These types of situations leave a lasting impression. read more

It is nice to have a new furnace installed but I was surprised when they told me that my old thermostat was just fine. Yes, at the time it worked. BUT I PAID FOR A NEW ONE. So today, years later, I have a dead thermostat. I have it at 28C. And freezing cold. Probably not a chace in hell of them giving me my thermostat even though I requested it at the time. I guess this is called profit. read more

I called Dunn Heating to get an old AC disconnected and removed from my property. (Very) Un-friendly staff, obviously not focused on client's experience. Beside, the technician gave me a quote 33% higher than the initial one, and finally, after looking into the unit in "depth", ended up refusing to do the service, making me understand he would make more money working on a heating systems because of the seasonal high demand. As I took a full day off to receive him, I suggested to at least disconnect the unit, and even offered my help to speed up the process for his other calls. He refused, and left. No "sorry", not even "goodbye". He even left my AC open with pieces on the floor, and have now to figure out what goes where. I am used to work with contractors on a regular basis. I never saw a company handling their customers that way! read more

I have dealt with Dunn Heating for many years and have always been extremely pleased with both their Sales and Service. Dunn just replaced my 18 year old furnace yesterday and everything went smoothly and the new furnace is running well. I will continue to call Dunn in the future. read more

Just had my furnace break down after 20 years. Called Dunn Heating and they had a service inspection in 30 min., a quote an hour later and replaced the furnace the same day. It couldn't get any better than that. read more

I had a very similar experience to the previous feedback. Called and booked an appointment. 30 minutes before the appointment I find a voicemail (I've been in meetings all morning) that says Dunn won't be coming today. Another job has come up (New furnace beats new AC) so they are going where the $ is. Well you won't get mine. read more
