Jayne Graham2025-07-11Trustindex verifies that the original source of the review is Google. Excellent service with Shawn. Very informative and professional. Jonathan Wake2025-07-11Trustindex verifies that the original source of the review is Google. From the very start of the process in our bathroom renovation, the customer service experience, punctuality, honesty, and transparency were top tier with Donaldson. They provided us with a stress free renovation as each trade was brought in and handled by them in a well orchestrated timeline. At the end only needing to pay one bill that included the subcontract costs. This job encompassed plumbing, drywalling/waterproof enclosure installation, electrical, and demolition. Every stage and every technician involved was fantastic. I highly recommend this company for any home improvement project. The job will be done right and the results are stunning! I have attached the before and after for our renovation, the before is the brown tiled style and the after is the beautiful Grey acrylic with better lighting. Drew McCallum2025-07-11Trustindex verifies that the original source of the review is Google. Exceptional Service – Highly Recommend Donaldson Heating and AC! Donaldson Home Heating has truly gone above and beyond for me on multiple occasions. Their service, responsiveness, and professionalism are outstanding. Recently, I had a water line break at one of my properties, and water was leaking into the floor below. Donaldson had a technician on site within just a couple of hours. They quickly diagnosed and resolved the issue, minimizing damage and stress. Another time, in the middle of a hot July evening, our AC unit failed and the indoor temperature was rising fast—already at 79°F. I called Donaldson’s emergency line and was amazed when a technician arrived within 45 minutes! Although the issue couldn’t be fixed that night, they had the necessary part ordered and the repair scheduled for the very next afternoon. Their communication and follow-through were excellent. In every interaction, their team has been professional, courteous, and incredibly efficient. I can’t recommend Donaldson Heating and AC enough. If you need fast, reliable, and friendly service, they’re the ones to call! John Bisset2025-07-11Trustindex verifies that the original source of the review is Google. Plumber arrived and quickly identified the water leak. He then repaired the problem. He left a very clean work area. We were totally happy with the service provided. Jay Graf2025-07-10Trustindex verifies that the original source of the review is Google. Jason was a great Donaldson employee any future work i need will be getting you guys again no question Holly Wallace2025-07-10Trustindex verifies that the original source of the review is Google.

WE INSTALL THE TOP FURNACE AND AIR CONDITIONER BRANDS
At Donaldson, we only install reliable, top-performing furnace and air conditioner brands that meet our standards for quality and efficiency.
To obtain an accurate equipment price you will need your home’s size measured for it’s heating and cooling load. This includes: floors, rooms, windows, doors, venting, and other details.
TIP: Be weary of any company promising you a ‘good’ furnace price over the phone based only on square footage. All homes must be measured to see what furnace size fits. A furnace that is too big will actually heat your home less, and a too small furnace will over-run and have a shorter life span.
