Heating and Air Conditioning Appliance Warranties

At Donaldson Heating and Air Conditioning, as a part of our peace-of-mind guarantee, we offer some of the best warranties in the industry.

Service Warranties

There are two warranties within our service & maintenance divisions:

Lifetime Replacement On Any Recommended Part Repair

When you purchase a Donaldson Heating and Air Conditioning recommended parts repair, you’ll receive our Lifetime Replacement Warranty. Should our recommended repair fail to do the job, you can rest easy knowing that we guarantee that component for the life of the equipment to the original purchaser.

Disclaimer: Donaldson Heating and Air Conditioning warrants and guarantees to the original purchaser, that should a customer accept and purchase Donaldson Heating and Air Conditioning’s recommended repair, such repair shall be free from defect in materials and workmanship under normal use and conditions for as long as the customer owns the residence in which the recommended repair was provided or until the unit in which the covered repair was performed, if applicable, is replaced. For full details, please contact our office at 519 439 4328.

90-Day Diagnostic Guarantee




At Donaldson Heating & Air Conditioning, we’ve brought together well-trained, highly skilled technicians that will perform industry-leading maintenance and accurately diagnose your system when things go wrong. In fact, we are so sure of this, that we back it up with a 90-day warranty. If your system has a problem within 90 days of us performing maintenance or diagnostic, we’ll return to diagnose the problem at no charge.

Installation Warranties

Depending on the products you purchase, we offer three different warranties. These are placed primarily on furnaces and air conditioners; however, they also cover other components such as:

 Water heaters  – 6 years
Fireplaces – 10 years
• Tube heaters – 6 years
• Pool heaters – 1 year

Standard Warranty (10-Year Warranty)

Air conditioner inspection

The last thing you should have to worry about is the reliability of your new HVAC system. At Donaldson Heating and Air Conditioning, we offer 10-year warranties on all of the furnace and air conditioners we install so that when a new component needs to be installed, we’ll have you covered for 10 years.

“No Lemon” Warranty

Manufacturers have admitted that 3% of their equipment can come from the factory with some kind of defect. At Donaldson Heating and Air Conditioning, we want to ensure that you only receive the best of the best. That’s why we guarantee that if you do receive a lemon (i.e. a furnace or air conditioner with a defect) that fails within the first five years, we will replace it with a brand-new current model, free of charge.

Disclaimer: The “No Lemon” Warranty covers major components such as heat exchangers and compressors. For more information, please contact our office at 519 439 4328.
