"Jim took the time to explain the current condition of my system and its layout while also discussing the best possible solutions for my situation. While the original plan was going to be a 2-day effort, his team was able to get all work completed in one day which was very convenient for me. I am very satisfied with the equipment and upgraded infrastructure of my HVAC system. The very first day I noticed a huge difference in the overall climate of my house!"

"We are extremely pleased with the product as well the quality service that Donaldson has provided for us over the many years that we have used them for our HVAC needs."

"Our salesperson/installer is the reason we used Donaldson a second time. Derrick is the utmost professional. He was knowledgeable about our system and went out of his was to get us the information we needed to make an informed decision. He installed our new geothermal system promptly and with great care to our home. I’ve already passed his card to a friend!"
