Common Problems We Fix
Recognizing an issue early can save your business thousands in repairs. Here's what our technicians diagnose and resolve every day.
No Heat or No Cooling
Whether your furnace won't fire or your AC isn't blowing cold, we diagnose and fix the root cause fast.
Poor Airflow & Ventilation
Weak airflow, hot/cold spots, or stale air are often signs of duct issues, dirty coils, or a failing fan motor.
Electrical & Controls Failures
Tripped breakers, faulty contactors, failed control boards, and thermostat issues are all in our wheelhouse.
Short-Cycling RTUs
Rooftop units that cycle on and off rapidly waste energy and wear out components quickly — we'll find out why.
Refrigerant Leaks
Low refrigerant leads to poor cooling performance, frozen coils, and compressor damage. We locate leaks and recharge properly.
Compressor & Motor Issues
Failed compressors, belt-driven fans, and blower motors are common in aging commercial systems — we repair or replace them.
Preventive Maintenance
Maintenance Plans That Pay for Themselves
A proactive maintenance plan is the single best investment you can make for your HVAC system. Regular service extends equipment life, lowers energy bills, and dramatically reduces the chance of a costly emergency breakdown. Our plans are customized to your equipment, usage, and budget.

Frequently Asked Questions
Common questions about commercial HVAC service in Calgary.
How often should commercial HVAC systems be serviced?
We recommend servicing commercial HVAC systems at least twice a year — once before the cooling season (spring) and once before the heating season (fall). High-use environments like restaurants may benefit from quarterly maintenance to prevent unexpected breakdowns.
What is a make-up air unit and do I need one?
A make-up air unit (MAU) replaces air that is exhausted from your building — especially critical in restaurant kitchens with commercial hood fans. Without proper make-up air, you can experience negative pressure, poor combustion, backdrafting, and uncomfortable drafts. Most commercial kitchens in Calgary are required to have one.
My rooftop unit is short-cycling. What does that mean?
Short-cycling means your RTU is turning on and off too frequently without completing a full heating or cooling cycle. Common causes include a dirty air filter, refrigerant issues, a faulty thermostat, or an oversized system. Left unaddressed, short-cycling accelerates wear and significantly shortens equipment life.
Can you service our HVAC system after hours or on weekends?
Yes. We offer 24/7 emergency service and can schedule planned maintenance outside of your business hours to minimize disruption. Just let us know your preferred time when you call.
What brands of commercial HVAC equipment do you work on?
Our technicians are trained to work on all major commercial HVAC brands including Lennox, Carrier, Trane, York, Daikin, Goodman, Rheem, Bryant, and American Standard, among others.
Do you offer maintenance contracts for multiple locations?
Absolutely. We work with multi-location businesses and property management companies to create customized maintenance agreements that cover all your sites under a single contract with consistent scheduling and reporting.
