WHat clients love most

Clients = ongoing support. You are never a one-time customer.

The unbeatable True Care Warranty – our 15 year warranty for a completely worry-free system

All Technicians work for Donaldson and are licensed under TSSA (no subcontractors). Techs do not perform work without going over findings and pricing with you first. Experienced Technicians will offer repairs/replacement options for you under our Repair Guarantee.

Professional quotes and upfront pricing on the spot. Plus receive a reminder text with a photo of the Technician on the way.

Our Comfort Advisors are not ‘salespeople’ – they perform free home heat loss/heat gain analysis for our Size Guarantee, offer pricing options and are there to answer any questions you might have about your home comfort. 




We were recognized as the fastest growing HVAC company on Canada’s Fastest-Growing Companies List 2020, voted London’s Favourite HVAC for Community Votes 2020, maintain an A+ rating with the Better Business Bureau and are Google Guaranteed*.



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.

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 Guarante

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.

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

 The Owner’s of Donaldson Heating & Air Conditioning, Jamie and Anna Donaldson, have been in HVAC for over 13 years. 

It all started with cold early mornings in their backyard where Jamie would make custom ductwork on a their picnic table. As Donaldson Heating & Air Conditioning grew, they realized how much families didn’t know about the impact HVAC can have on their home and their health.

After one too many times of seeing homeowners being taken advantage of by predatory business practices, low-quality products and not being offered ongoing support, Jamie and Anna knew they wanted to do something about it. Before they knew it, True Care was born!

As a local family-owned business, we provide above-and-beyond service, install reliable brands, offer ongoing support, explore and go over all options with you and protect you by sharing the information you need to make informed decisions about your home comfort.

Long story short, we will always be a friend in your home!

products & brands

As the largest Trane dealer in the London region and to serve you better, our technicians are trained on top of the line Trane equipment and on some of the more complex systems in order to service all makes and models of furnace and air conditioners.

To keep things simple, we strive for a ‘good, better, best’ system. Here are some of the furnace and air conditioner brands we offer.


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.

If you’re looking for something fast & affordable, Goodman may be the way to go.
