What to Expect
A furnace failure in Calgary isn't just uncomfortable — it can be dangerous. R N T Plumbing and Heating offers 24/7 furnace repair to get your heat back quickly and safely. Our certified technicians service all major brands and models.
From ignitor and flame sensor issues to blower motor failures and thermostat problems, we diagnose accurately and repair it right the first time. We'll also flag safety concerns like cracked heat exchangers before they become a risk.
A Calgary winter can drop to -30°C and stay there for days, so a reliable furnace isn't a luxury — it's a safety issue. Our technicians carry common parts for major brands and arrive prepared to diagnose and repair most issues on the first visit, so your family isn't left in the cold.
We don't just fix the symptom. Every repair includes a safety check of the heat exchanger, venting, and combustion, because a hidden crack or venting problem can put carbon monoxide in your home. If we spot a safety concern, we'll tell you straight away and explain your options.

"I manage several properties in Calgary. I have used several different plumbing companies over the years and by far R N T Plumbing has been the best Most recently another company came in because 3 out of 4 sinks had no water. They said all 3 faucets had to be replaced. I decided to get a second opinion from R N T and sure enough no need for replacement, just a part. Saved me over $2000. Such a great team, friendly, very responsive and they want to help, not just make money. Thank you R N T."

"Bobby showed up on time and inspected my hot water heater. I thought I was going to need a replacement that was going to cost me thousands of dollars, and he ended up saving that for me! He also installed a set of shower taps and had to run some new lines. He was professional and courteous and when I need his help again, I know he will be there, on time, professional and clean up after himself."
