COMMERCIAL ROOFTOP HVAC

Yes, you usually need a permit to install rooftop HVAC units. This confirms everything meets Calgary’s safety and building codes so your system is installed properly and legally. This permit falls under the same mechanical permit as residential installs.

At One Stop HVAC, we handle the permits and paperwork so you don’t have to worry about what satisfies Calgary’s building regulations.

Most installations take anywhere from a few days to a couple of weeks, depending on the size of the system and the complexity of the job. A straightforward replacement might only take 2 to 5 days, while larger projects that involve ductwork changes or crane lifts can take a bit longer.

Since we offer 24/7 service, we’ll work around your schedule to minimize disruptions and keep your business running smoothly. After a site visit, we’ll provide a clear timeline so you know exactly what to expect.

In general, you’ll want about 3 to 6 feet of open space around the unit. This gives it enough room to “breathe” properly and makes it easier (and safer) for us to do any maintenance or repairs down the line. Every building’s a little different, though, so when we come out for a site visit, we’ll take a good look at your setup and make sure everything’s spaced out just right and up to code.

Definitely! Our rooftop HVAC units are designed and installed to handle Calgary’s tough weather, including cold winters, strong winds, and heavy snow, so your business stays comfortable year-round.

We only recommend and install reliable, weather-tested brands we trust, so your system keeps performing no matter the season.

There are a few obvious signs your system might be struggling, for example: frequent breakdowns, rising energy bills, inconsistent temperatures throughout your building, strange noises, or unusual smells. These can all point to underlying issues that need attention.

If your unit is 15 years or older, it might be nearing the end of its lifespan. We’ll inspect your system thoroughly and give you honest advice to see if a replacement or repair is better for your situation.

Most commercial buildings can have rooftop HVAC units installed. However, we always start with a thorough assessment of your building and rooftop to recommend the best, most efficient solution for your unique needs.

With regular maintenance and proper care, a commercial rooftop HVAC unit typically lasts between 15 and 20 years, giving you long-term comfort and reliable performance.

We offer a 10-year limited product warranty on trusted brands so you can enjoy a great commercial HVAC unit for as long as possible.
