How Quickly Will You Be Here After I Book an Appointment?
We provide an accurate time estimate at the time of booking. If booking for a future date, we will confirm the appointment the day prior.
What Types of Furnaces Can You Service?
Our HVAC technicians are experienced with nearly any residential furnace sold in Alberta since the 1950s and onward. So long as replacement parts are available when needed, we can service nearly any type of forced-air furnace.
Fun fact: the oldest furnace we’ve repaired was from 1912!
Why Do You Exclusively Install Bryant Furnaces?
Your furnace is a major appliance, and it’s we don’t believe that compromising on reliability, build quality, and longevity is acceptable when you live in a climate that regularly sees temperatures of -40 below.
Bryant furnaces are a great value, offering homeowners proven long-term reliability and comfort. We have worked on thousands of furnaces and are confident in Bryant.
What Are Your Warranties On Furnace Repairs And New Furnace Installations?
An investment in your furnace should be made with peace of mind. AKA, we’ve got your back!
Furnace Repairs
We use high-quality OEM or OEM-equivalent parts (when OEM is not possible) and provide a 1-year warranty on parts and labour. If our repair fails, we’ll be back to fix it at no-charge.
New Furnace Installations
We back our furnace installations with a 1-year labour parts warranty, and the Bryant furnace itself has a general 10-year parts warranty (20 years on the heat exchanger and some heat exchangers have a lifetime warranty). Bryant’s generous warranty is part of why we like them so much.
