Furnace Repair & Replacement in St. Albert
When your furnace quits on a bitter January night or your AC gives out mid summer, you want a local team that picks up, shows up, and does the job right. That has been City Furnace Mechanical for more than 20 years. Licensed journeyman technicians, honest advice, and 24/7 emergency service for homes and businesses across St. Albert and the Sturgeon region.
We know St. Albert homes, old and new
St. Albert is one of the oldest communities in Alberta, and it shows in the housing. Historic neighbourhoods like Grandin and Mission along the Sturgeon River sit near newer builds on the north and west sides, and they do not heat the same way. A system sized for a modern subdivision is the wrong call for an older character home, and we treat each one on its own terms.
The climate here is hard on equipment. Winters drop well below -30 and summers push past +30, so a system has to be sized and installed for real extremes, not a mild average. After more than two decades serving the region, we know what holds up through a St. Albert winter and what quietly fails when you need it most.
We are a referral-based business, which means our reputation is built one honest job at a time. No pressure, no upselling, no scare tactics. Just quality work from licensed journeyman professionals who pull the proper permits and stand behind what they do.
A third of St. Albert was built before 1980
Of the 25,935 occupied homes the 2021 census counted in St. Albert, 8,345 were built between 1961 and 1980. That is close to a third of the city, and those houses were designed around a furnace that no longer exists: bigger, less efficient, and moving far more air through ducts that were sized for it.
Put a modern high-efficiency furnace into that house without touching anything else and it will run, but it will fight the ductwork the whole time. Undersized returns are the usual culprit behind the room that never warms up and the fan that sounds like it is working too hard. It is also why a straight swap is sometimes the wrong advice, and we will say so before you pay for one.
The same homes rarely have provision for air conditioning, because nobody planned for it in 1972. That is solvable, and it is a different conversation from the one we have in a newer part of the region.
When the furnace quits in St. Albert
A no heat call gets a licensed journeyman and a real diagnosis, not a parts guess. Most repairs are finished on the first visit, because the van carries what fails most often on the systems around here.
Evenings, weekends and holidays are covered for emergencies and urgent calls. We will tell you honestly when we can get there rather than promise a window we cannot keep, and if the furnace is far enough gone that a repair only buys you weeks, we will say that too instead of selling you the part.
Replacing a furnace in an older St. Albert home
The 8,345 homes built here between 1961 and 1980 are the ones most often on their second or third furnace, and they are the reason a replacement in St. Albert is rarely just a swap. The ductwork was sized for a bigger, thirstier machine, and a modern high-efficiency furnace put in front of undersized returns will run, but it will fight them.
So the quote starts with someone looking at the house: the heat loss, the returns, where the new venting can exit and keep its clearances, and where the condensate drains. The permit goes through the City of St. Albert and we pull it. You get one written number with all of that inside it.
A two furnace replacement in St. Albert


This house ran two mid-efficiency Carrier furnaces side by side, both venting upward in galvanized metal pipe. It is the arrangement a lot of St. Albert basements still have, and it works until the day it does not.
They were replaced with two high-efficiency units. The part worth looking at in the second photograph is not the new cabinets, it is the white plastic pipe: a condensing furnace vents out through the wall rather than up, so the exhaust route had to be rebuilt, not reconnected. The filter cabinet between them is new too.
The equipment here was the homeowner's choice. We fit one manufacturer most of the time and we are straight about why, but it is your house and your money. If you want something else and it is right for the job, that is what goes in.

Real reviews from customers across the greater Edmonton area.
As first-time homeowners (and renovators), Nick worked with us, at our pace, and provided excellent information to allow us to make the right choice. We are very satisfied with our new furnace and ducting, and refer Nick and City Furnace every opportunity we get. Thanks again!
I was impressed from the minute I met you. I liked your honesty and integrity, and everyone that came into contact with you while you worked was equally impressed. Your knowledge and experience are evident in the work you do. I would highly recommend you to anyone in need of furnace repairs or replacement.
We had Nick from City Furnace redesign our heating system. We live in an older home that had two old furnaces, and because of changing safety code we needed to go to one furnace. This was not an easy fix, but Nick handled the tough job with ease, in a timely fashion, for a very fair price and with exceptional workmanship. I work in construction myself and appreciate his hard work and showing up when scheduled.
