Whether you're adding air conditioning for the first time, replacing an aging unit, or dealing with a breakdown mid-summer, our licensed technicians provide reliable, quality work at every job.
Central AC Installation
A central air conditioning system uses your home's existing ductwork to distribute cooled air throughout the house. Installation involves an outdoor condenser unit, an indoor evaporator coil (mounted on your furnace), and refrigerant lines connecting the two:
- New installations: Adding AC to a home that already has forced-air heating and ductwork — the most straightforward upgrade
- System replacement: Upgrading an older, inefficient unit to a high-SEER model
- High-efficiency units (16–20 SEER): Lower operating costs and quieter operation
- Two-stage and variable-speed compressors: More precise temperature control, better humidity removal
- Proper sizing: Manual J load calculations ensure your new unit is the right size — not too large, not too small
- Financing available: Spread payments on new AC installations through Financeit
Central AC Repair
When your air conditioner fails on a hot Manitoba day, we respond promptly. Common issues we repair:
- Not cooling: Refrigerant leaks, failed compressor, frozen evaporator coil
- Not turning on: Failed capacitor, contactor issues, electrical problems
- Poor airflow: Clogged filter, frozen coil, ductwork issues
- Unusual noises: Fan motor, compressor, or refrigerant line issues
- Short cycling: Oversized unit, refrigerant problems, thermostat issues
- Refrigerant service: Leak detection and recharging (licensed refrigerant handling)
Annual AC Maintenance
A spring tune-up before the cooling season catches problems early and keeps your system running efficiently. Our service includes:
- Condenser coil cleaning
- Refrigerant level check
- Electrical connection inspection and tightening
- Capacitor and contactor testing
- Evaporator coil inspection
- Thermostat calibration and system performance check
Also explore heat pumps for year-round heating and cooling, or ductless mini-splits for areas without ductwork. See all cooling services.
Central AC Questions & Answers
How long does a central air conditioner last?
A central air conditioner typically lasts 15–20 years with proper annual maintenance. Manitoba's shorter cooling season means AC units often run fewer hours per year than in warmer provinces, which can extend equipment life. Key to longevity is annual spring tune-ups and keeping the outdoor condenser coil clean.
What SEER rating should I look for in a new central AC?
SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency. The minimum in Canada is 13 SEER, but we recommend 16 SEER or higher for better energy savings. In Manitoba, where AC season is shorter, the payback on very high-efficiency units is longer — a 16–18 SEER unit is usually the sweet spot of cost and efficiency.
My air conditioner stopped working mid-summer. What should I check first?
Check your thermostat settings, replace or inspect your furnace filter (a clogged filter can cause the coil to freeze), reset your circuit breaker, and verify the outdoor unit is powered on. If none of these resolve the issue, call us — common causes include a failed capacitor, low refrigerant, or a tripped high-pressure switch.
