Donaldson Heating & Air Conditioning

Jan 2026

I have been a client of Donaldson's for several years. They have always gone above and beyond in customer service but multiplied that this past weekend when our furnace was not functioning properly in 5 degree weather. Jeff drove to our house in a terrible snowstorm on a Saturday at 6 PM because he remembered us and didn't want to leave us in that terrible cold all weekend. Thanks to Jeff and to Donaldson's!

Donaldson's excellent team installed an entirely new, energy-efficient HVAC system and humidifiers in our home. They took their time to do so in a careful, clean, and thorough manner. We also used Donaldson for our commercial properties. They do excellent work and are good, trustworthy people. Highly recommended!

Arrived when promised. Great job removing old unit and installing new one. Jeff and Terry are very friendly and professional.
