“Can’t say enough how grateful I am to this company. They went above and beyond to keep my heat running when it was subzero outside. Showed up on a Sunday night in frigid temps to help. Replaced my tired furnace 48 hours later. Super kind and reasonable. Customer for life.” – Megan H.

“Anthony P. was excellent during the whole process. We ran into several obstacles during the duct work install and Anthony with the install team worked through it to resolve the issues. We upgraded our duct work size and added return ducts. Also we did the cleaning and Aeroseal. We were happy with the end result.”

“I am writing this review in regards to the service I received from Dornbos Heating & Air Conditioning .I'm a skeptical person not easily impressed however I was pleasantly surprised at level of quality service we received regarding the installation of a new AC unit in my 30 year old home. Their attention to details was quit impressive and there caring nature was refreshing in this indifferent society we live in today. Jakub and Hunter were great installers !”

“Doornbos has installed my furnace and air conditioning units and maintained them for 46 years. Cheerful and friendly Joyce calls to set up the spring and fall maintenance calls and lets me know when the serviceman is on his way. The service men are professional and explain what they have done. I do vote Doornbos for Best Heating and Cooling of Southland 2023!”
