Company Warranties & guarantees

We stand behind everything we do – these written guarantees are 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

Should one of our experienced Technicians recommend and perform a specific furnace or air conditioner repair that fails to fix the original issue within the first year, we will make it right. Also be sure to ask us for more information on our 90-Day Diagnostic Guarantee.

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!

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.

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.
