How much does commercial HVAC maintenance cost in Calgary?

Commercial HVAC maintenance costs in Calgary vary based on the number and type of units, building size, and service frequency. Per-visit costs typically range from $200–$500, while annual maintenance contracts for commercial properties generally range from $1,000 to $10,000+ per year depending on system complexity. Next Air offers customized maintenance plans — contact us for a free quote.

How often should commercial HVAC systems be serviced in Calgary?

Most commercial HVAC systems in Calgary should be serviced at least twice a year — ideally in spring and fall before peak seasons. Systems with air filters (such as rooftop units and make-up air units) should receive a minimum of 3–4 service visits per year. Given Calgary's extreme winters and temperature swings, more frequent maintenance helps prevent costly cold-weather breakdowns.

How long does a commercial rooftop HVAC unit (RTU) last?

With proper maintenance, a commercial rooftop unit (RTU) typically lasts 15–20 years. In Calgary's harsh climate — including severe winters and Chinook temperature swings — units that are poorly maintained may fail sooner. Regular maintenance by certified technicians is the single biggest factor in extending RTU lifespan. If your unit is over 15 years old and experiencing frequent breakdowns or rising energy costs, it may be time to consider replacement.

How do I know if my commercial rooftop unit needs repair or replacement?

Signs that your commercial RTU may need repair or replacement include: frequent breakdowns, rising energy bills, inconsistent temperatures throughout your building, unusual noises or smells, and age over 15 years. A general rule: if repair costs exceed 30–40% of the cost of a new unit, replacement is usually the better investment. Next Air will inspect your system and give you an honest recommendation.

How much does it cost to install a commercial rooftop HVAC unit in Calgary?

Commercial rooftop unit (RTU) installation in Calgary typically costs between $8,000 and $25,000+ CAD per unit, depending on size (tonnage), system complexity, crane requirements, ductwork changes, and permit fees. City of Calgary mechanical and gas permits are required and are handled by our licensed technicians. Contact Next Air for a free site assessment and installation quote.

Yes, Next Air services all types of commercial refrigeration equipment throughout Calgary. Our technicians are experienced with walk-in coolers and freezers, refrigerated display cases, ice machines, and industrial refrigeration systems. We serve restaurants, grocery stores, food service businesses, and more — keeping products safely refrigerated and your operations running.

What are the benefits of a commercial HVAC maintenance contract?

A commercial HVAC maintenance contract provides: priority emergency service, reduced risk of unexpected breakdowns, lower long-term repair costs, improved energy efficiency, extended equipment lifespan, and predictable budgeting. Businesses on maintenance contracts with Next Air also receive detailed service reports after every visit, making it easier to plan capital expenditures and track system health.

Why should I choose a commercial-only HVAC company instead of a residential contractor?

Commercial HVAC systems are significantly more complex than residential units — they handle larger loads, more complex ventilation requirements, and stricter building codes. Next Air focuses 100% on commercial and industrial HVAC, meaning our technicians are specifically trained on commercial equipment like rooftop units, make-up air systems, tube heaters, and commercial refrigeration. Residential HVAC companies often lack the expertise and equipment for commercial-scale systems.

How much can Calgary businesses save with energy-efficient commercial HVAC?

Most Calgary businesses save 15–30% on energy costs after upgrading to high-efficiency HVAC equipment or getting proper maintenance from Next Air. Calgary's long heating season and frequent temperature extremes make energy-efficient systems especially valuable here — they recover faster after Chinooks, maintain more consistent temperatures, and use significantly less energy during deep freezes. We provide a free energy assessment to show you the exact savings potential.

What permits are required for commercial HVAC installation in Calgary?

The City of Calgary requires mechanical and gas permits for commercial HVAC installations, including rooftop unit replacements. Permit fees can range from $500 to $2,000+ depending on project scope. As a licensed commercial HVAC contractor, Next Air handles all permit applications and ensures every installation meets Calgary building codes and Alberta safety standards.

How long does a commercial HVAC installation take?

Most commercial HVAC installations in Calgary take anywhere from a few days to a couple of weeks depending on system size and complexity. A straightforward rooftop unit replacement can often be completed in 2–5 days, while larger projects involving new ductwork, crane lifts, or full system design may take longer. Next Air works around your schedule to minimize business disruption and provides a clear timeline after a site visit.

Is it worth upgrading an older commercial HVAC system in Calgary?

In most cases, yes. Older commercial HVAC systems — especially those 15+ years old — are significantly less efficient than modern units and are more expensive to run and repair. In Calgary's climate, newer systems handle extreme cold more effectively, recover faster from Chinook temperature swings, and offer smart controls for better energy management. Most Calgary businesses recoup upgrade costs through energy savings within a few years.

What is a make-up air unit and does my commercial building need one?

A make-up air unit (MAU) replaces air that is exhausted from a commercial building — such as through kitchen exhaust fans, industrial ventilation, or bathroom fans. Without proper make-up air, negative pressure can cause heating issues, back-drafting of combustion appliances, poor indoor air quality, and drafts. Many commercial buildings in Calgary — especially restaurants, warehouses, and industrial facilities — require make-up air units to meet ventilation code requirements. Next Air can assess your building's needs and install or service commercial make-up air systems.

How do I choose the right commercial HVAC contractor in Calgary?

When choosing a commercial HVAC contractor in Calgary, look for: a contractor who specializes in commercial systems (not just residential), licensed and insured technicians, experience with your specific equipment type and brands, transparent upfront pricing, detailed service reports, strong local reviews, and 24/7 emergency availability. Next Air focuses exclusively on commercial and industrial HVAC, serving businesses across Calgary with certified technicians who know local building codes and Alberta's climate demands.

Commercial HVAC Maintenance Plans in Calgary: Protect Your System Year-Round

Calgary’s commercial buildings face some of the most demanding HVAC conditions in Canada. Sub-zero winters lasting six months. Chinook wind cycles swinging temperatures 20°C in hours. Hailstorms in summer. Dusty, dry air year-round. If your commercial HVAC system isn’t on a proper preventive maintenance plan, it’s operating on borrowed time.
Next Air’s commercial HVAC maintenance plans are built specifically for Calgary’s climate — not generic national programs. Our certified technicians know what Alberta’s weather does to heating and cooling equipment, and our maintenance schedules are structured to catch problems before they become emergencies.

Why Preventive Maintenance Matters for Calgary Businesses

HVAC equipment that receives regular professional maintenance lasts 30–40% longer, operates 15–30% more efficiently, and suffers 80–90% fewer emergency breakdowns. Most manufacturer warranties require documented annual service to remain valid.
For a typical Calgary commercial building spending $2,000–$5,000 per month on heating and cooling energy, a 20% efficiency improvement through our commercial energy saving upgrades and regular maintenance represents $400–$1,000 in monthly savings — often more than covering the cost of a maintenance plan.

REAL-WORLD SAVINGS

Next Air customers report saving an average of $3,000 per year after enrolling in a commercial HVAC maintenance plan — through reduced energy consumption, fewer emergency repairs, and extended equipment lifespan.
