Donaldson Heating & Air Conditioning, now known as Donaldson Home Services is owned & operated by Jamie and Anna Donaldson.
After seeing one too many homeowners being taken advantage of by predatory business practices, false information and over-priced services, Jamie and Anna knew they wanted to do something about it.
In 2013, Jamie started making ductwork on a their picnic table in the backyard. He would work from 5am to 12am if it meant helping someone be more comfortable at home. As Donaldson Heating & Air Conditioning grew, they realized how much families didn’t actually know about how much HVAC can affect their home and health.Before they knew it, the True Care Warranty was born!
Our purpose is to keep you safe & comfortable by providing WOW-service, reliable brands & products, offer ongoing support programs, and by helping you make informed decisions about your home comfort.
As a local family-owned business, we will always be a friend in your home!

Size Guarantee
The only viable way to know what size furnace or air conditioner your home needs is to perform a Heat Loss/Heat Gain Analysis that considers specific construction elements of the home such as size, windows, insulation, number of people and more. The proper size equipment will ensure optimal energy efficiency, operation and help you get the longest life out of your system.
No "lemon'" Guarantee
No one likes a dud. Manufacturer’s have admitted that 3% of new equipment may come with a defect. Should you heat exchanger or compressor fail with proper maintenances in the first 5 years, we will replace it free of charge.
The Unbeatable 15 year True Care Warranty
True Care was inspired by how we truly care. With the purchase of a premium furnace, get 15 years of parts & labour coverage, plus a free maintenance (including filter) every year, an upgraded air filtration system, wifi thermostat, exclusive discounts & priority booking – more.
products & brands
For quality, comfort and peace of mind, our technicians are trained on top of the line Trane furnaces and air conditioner and on some of the more complex systems so that we can offer you the most options.
When it comes to furnaces and air conditioners, we strive for a ‘good, better, best’ system. Here are some of the best brands we offer.
Trane
RATED MOST RELIABLe
Trane is an American Standard brand that offers some of the most robustly tested equipment in the industry! Trane equipment forgoes extreme heat, pressure, freezing and shock tests to ensure it can maintain performance and efficiency in extreme weather. Trane offers one of the only furnaces with a full stainless steel heat exchanger backed by their manufacturer warranty for 99 YEARS and is actually what inspired our extended 15 year True Care Warranty.
We also offer a more affordable option air conditioner known as RunTru by Trane.
If the last thing you want to be thinking about is your furnace or air conditioner, Trane is a great option for you!
lennox
Top-Tier Efficiency
Lennox is a brand known for its dependability when it comes to premium home comfort. Lennox has been pursuing perfect air for nearly 130 years. The products are technologically advanced, manufactured to the highest standards, rigorously tested and built to stand the test of time. Modern Lennox products are known for their efficiency and innovation. Many of the brand’s top products reach SEER (Seasonal Energy Efficiency Ratio) ratings that other brands can’t match. While Lennox products are often seen as lavish, these energy savings are often worth the upfront cost.
Goodman
Most AFFORDABLE
Goodman is a well-known brand and is the most affordable furnace and air conditioner product we install. Although Goodman furnaces and air conditioners do not use the same premium materials and does not go through the same level of testing as Trane and Daikin, Goodman is still a reliable brand. Our Goodman products come with a standard 10 year manufacturer parts warranty and can be partnered with one of our Maintenance Care Plans for added piece of mind.
