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.

Do you service commercial refrigeration systems in Calgary?

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.

Reznor Tube Heaters Calgary: Radiant Infrared Heating That Works in Alberta's Harshest Winters

If you operate a warehouse, aircraft hangar, car dealership, or open-plan industrial facility in Calgary, you already know that conventional forced-air heating has its limits. Every time a loading dock door opens, warm air escapes — and your energy bills climb. Reznor tube heaters solve this problem by delivering infrared radiant heat directly to people, floors, and equipment, not just the air.
NextAir.ca is Calgary’s trusted Reznor tube heater supplier and installer, helping facilities across the city cut heating costs while maintaining comfortable working temperatures even during Alberta’s most punishing cold snaps.

How Do Reznor Tube Heaters Work?

Unlike unit heaters that warm the air, infrared tube heaters work like the sun: they emit radiant energy that heats solid objects and people directly. A gas burner heats a long steel tube, which radiates infrared energy downward across the facility floor. Because this heat isn’t carried in the air, opening a large door or having poor ceiling insulation has far less impact on comfort. This makes Reznor tube heaters extremely effective for:

Distribution centres and fulfillment warehouses with frequent dock door operation
Automotive service bays and car dealership service departments
Aircraft hangars and FBOs at Calgary International Airport and Springbank Airport
Agricultural buildings, barns, and equipment storage facilities
Recreational facilities like arenas, curling rinks, and indoor sports facilities

Advantages of Reznor Tube Heaters for Calgary Facilities

Energy Efficiency

Reznor tube heaters can reduce heating energy consumption by 30–50% compared to unit heaters in facilities with high air change rates. Because heat isn’t wasted on warming stratified air near the ceiling, you’re directing energy exactly where it’s needed.

Comfort at Floor Level

Radiant tube heaters warm the floor slab and lower levels first — creating a far more comfortable working environment for employees on their feet all day. In Calgary’s cold winters, this translates directly into employee productivity and reduced absenteeism.

No Ductwork Required

Reznor tube heaters are suspended overhead and connected directly to your gas supply line. There’s no ductwork to plan around, clean, or repair — simplifying installation and reducing maintenance over the life of the system.

Quiet Operation

With no blower fan required to distribute heat, Reznor tube heaters operate virtually silently — an advantage in automotive showrooms, healthcare facilities, and any environment where noise is a concern.

Reznor Tube Heater Models Available Through NextAir

Reznor CODF Series — Continuous Linear Tube Heaters

The CODF Series provides continuous tube heating across spans from 20 to 60+ feet. This model is particularly popular in Calgary warehouses where even heat distribution across wide floor areas is essential. The CODF can be configured in straight, L-shape, or U-shape layouts to match your facility footprint.

Reznor EGHB Series — High-Low Control

High-low modulation allows the EGHB to operate at full capacity during warm-up and reduce to a lower output for maintenance heating — significantly reducing gas consumption during occupied hours while maintaining setpoint temperatures.

Reznor STS / STU Series — Single-Stage Units

For smaller Calgary facilities or zone heating applications, the STS and STU series provide cost-effective radiant heating in a compact tube format, ideal for targeted comfort zones within a larger space.

Tube Heaters vs. Unit Heaters: Which Does Your Calgary Facility Need?

Many of our Calgary clients ask whether they need tube heaters, unit heaters, or a combination. Here’s a practical guide:

High door traffic (loading docks, drive-through bays): Tube heaters are significantly more efficient because radiant heat is not lost when doors open.
Enclosed, well-insulated spaces: Unit heaters can be equally effective and are often lower in upfront cost.
Mixed-use facilities: A hybrid approach using tube heaters in high-traffic zones and unit heaters in enclosed offices or storage areas is common in Calgary industrial parks.
Spaces requiring spot comfort heating: Tube heaters excel at warming specific work areas without heating an entire building.

Frequently Asked Questions — Reznor Tube Heaters Calgary

Are Reznor tube heaters safe for occupied spaces in Calgary?

Yes. Reznor tube heaters are designed and CSA-certified for installation in occupied commercial and industrial spaces. They combust gas in a sealed burner assembly, and modern units include multiple safety controls including flame sensors, pressure switches, and high-temperature limits.

What's the typical installation time for a Reznor tube heater in Calgary?

A single tube heater installation typically takes one to two days including gas piping, suspension, venting, and commissioning. Larger multi-heater projects in big Calgary warehouses may take three to five days depending on scope.

Can tube heaters be used with a building automation system (BAS)?

Yes. Reznor tube heaters are compatible with most commercial thermostat and BAS control systems, allowing integration with your facility’s overall building controls for scheduled operation, set-back temperatures, and remote monitoring.

How often do Reznor tube heaters need servicing in Calgary?

Annual preventive maintenance is recommended and often required to maintain warranty. NextAir offers service contracts for Reznor tube heaters across Calgary, covering burner cleaning, ignition system inspection, gas pressure verification, and safety control testing.
