Your protection

We stand behind everything we do – these written guarantees were designed just for you. 

Inclusive & Upfront Pricing

Whether it’s a repair or you are considering a new furnace or air conditioner, no one likes surprises. To make things as easy and as transparent as possible, most of our pricing is inclusive (parts & labor). Find comfort in your home and in your budget.

90-Day repair Guarantee

If we’ve been in your home within 90 days and you’re still having the same problem, we will come look at it again with no additional trip charge. If you go ahead with a Technician’s professional repair recommendation, get Lifetime Repair Guarantee on that repair.

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.

our story -
a friend in your home


Donaldson Heating & Air Conditioning, 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 12pm 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!

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.

our latest addition

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.


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!

Goodman is a well-known brand and is the most affordable furnace and air conditioner product we install.
