See Why 200+ Calgary Homeowners Gave Us 5 Stars
We hired Comfort Union to install new GREE heat pump, IBC Combi boiler and IBC AHU air handler. We don’t have to rely on a gas furnace for heating anymore. They were very professional and punctual. Highly recommended.
Love the new water heater purchased from Comfort Union. Great service from beginning to end. Thanks to Muhammed (install Technician) and all the staff. I would highly recommend Comfort Union.
Our furnace unexpectedly failed and we needed a replacement right away. Ian at Comfort Union made it a priority to provide a quote same day. The installation team lead by Mohammad were professional.
Frequently Asked Questions Calgary HVAC Services
How much does furnace repair cost in Calgary?
Most furnace repairs in Calgary range from $150 to $600, depending on the part and complexity. Simple fixes like a flame sensor or ignitor are on the lower end. Larger components like a blower motor or control board cost more. At Comfort Union, there is no service fee, you pay only for parts and labour, with the full price confirmed before any work begins.
How quickly can you respond to an emergency furnace repair in Calgary?
Comfort Union offers true 24/7 emergency furnace repair across Calgary. In most cases our technician is at your door within 2 hours of your call, including nights, weekends, and holidays. Calgary winters don’t leave room for delays, and neither do we.
Do you repair all furnace brands in Calgary?
Yes. Our licensed technicians are trained on all major furnace brands including Lennox, Carrier, Trane, Goodman, Rheem, Keeprite, Daikin, Bryant, Ruud, American Standard and more. If it’s installed in a Calgary home, we service it.
Should I repair or replace my furnace?
A good rule of thumb for Calgary homeowners, repair if your furnace is under 15 years old and the repair costs less than $1,000. Consider replacing if the system is 15–20 years old, repairs are frequent, or a single repair exceeds half the cost of a new unit. Our technicians give you an honest assessment with no pressure either way.
Do you offer a warranty on furnace repairs?
Yes. Every repair completed by Comfort Union is backed by our parts and labour warranty. If we fix it and the same issue returns, we come back at no charge, no arguments, no hidden conditions.
How long does a furnace repair take?
Most common repairs such as sensors, igniters, and thermostats are completed in under 2 hours, same day. More complex repairs involving blower motors or control boards may take 3–4 hours. Our technicians carry the most common parts on every van, so most Calgary homes have heat restored on the first visit.
Do you charge extra for after-hours or weekend furnace repairs in Calgary?
No. Comfort Union charges the same rate regardless of when you call evenings, weekends, or holidays. A furnace breakdown at 2am shouldn’t cost more than one at 2pm. Our pricing is transparent and confirmed upfront every time.
How long does a furnace last in Calgary?
Most furnaces last 15 to 20 years with proper annual maintenance. Calgary’s extreme winters put more demand on heating systems than milder climates, so regular tune-ups are essential. If your furnace is over 15 years old and breaking down frequently, it may be more cost-effective to replace it.
Do you service boilers in Calgary?
Yes, boiler installation, repair, and maintenance is one of our specialties. We service all boiler types including combi-boilers and hydronic heating systems. Comfort Union is one of the few Calgary HVAC companies with dedicated boiler expertise alongside furnace services.
Are your HVAC technicians licensed in Alberta?
Yes. All Comfort Union technicians hold valid Alberta trade certifications including Red Seal HVAC/R, Gas Fitting Ticket, Refrigeration Mechanic 313D, and Sheet Metal Worker. We are fully licensed, WCB insured, and BBB accredited HVAC & Plumbing Licence No: 16356719.
