Old AC Costing You More? Here’s When to Upgrade
Frequent Breakdowns
If your AC constantly needs repairs, from capacitor failures to compressor malfunctions, a replacement may be more cost-effective than ongoing service calls.
Costly Repairs
Major fixes like compressor replacements, refrigerant leaks, or motor failures can add up. If repair costs approach the price of a new unit, upgrading makes financial sense.
Poor Cooling Performance
If your AC struggles to reach or maintain the set temperature, issues with refrigerant levels, coil efficiency, or thermostat calibration could indicate it’s time for an upgrade.
Inconsistent Airflow
Hot and cold spots in your home may be caused by failing blower motors, leaky ducts, or restricted airflow. A new system with proper ductwork optimization ensures even cooling.
Outdated or Inefficient System
Older AC units with low SEER ratings and single-stage compressors waste energy. Upgrading to a high-efficiency model reduces electricity use and enhances cooling.
Rising Energy Bills
Aging systems lose efficiency over time, forcing them to work harder. High-SEER-rated ACs with variable-speed compressors reduce energy waste and operating costs.
Strange Noises
Unusual grinding, buzzing, or rattling sounds could mean motor wear, loose components, or a failing compressor—signs it’s time to consider a new system.
Unpleasant Odors
Musty or burnt smells from your AC could indicate mould in the condensate drain, electrical issues, or refrigerant leaks. A new unit ensures cleaner, fresher air.
Unit is Over 10-15 Years Old
Most ACs last 12-15 years. If yours is nearing the end of its lifespan, a new energy-efficient system will provide better cooling, improved air quality, and lower maintenance costs.

Frequently Asked Questions
How much should it cost to replace an AC unit?
The cost of replacing an AC unit varies based on system size, SEER rating, and installation complexity. In Mississauga, prices typically range from $3,000 to $7,500 for residential systems and higher for commercial units.
What is the $5,000 AC rule?
The $5,000 rule helps determine whether to repair or replace an AC unit. Multiply the cost of the repair by the age of the unit—if it exceeds $5,000, replacing the system is often the better option.
How much does it cost to have air conditioning installed?
AC installation costs depend on unit type (central, ductless, or commercial), ductwork modifications, and smart thermostat integration. Expect prices from $2,500 to $10,000 depending on system efficiency and home size.
What is the 3-minute rule for air conditioners?
The 3-minute rule ensures compressor protection by preventing rapid on-off cycling. If an AC is turned off, wait at least 3 minutes before restarting to avoid pressure buildup that can damage the unit.
How long to wait before turning on the air conditioner after installation?
After installation, wait at least 24 hours before turning on your new AC if it was placed on its side during transport. For standard installs, a technician will ensure the system is ready to run immediately.
How do I know what size AC unit I need?
Proper AC sizing depends on home square footage, insulation levels, window placement, and climate conditions. Our experts perform manual J load calculations to determine the ideal system for your space.
How long does AC installation take?
A standard central AC installation takes 4 to 8 hours, while a ductless mini-split setup may take a full day. Complex projects, like zoning system integration or duct modifications, can take longer.
Is a permit required for AC installation in Mississauga?
Yes, most municipalities, including Mississauga, require a permit for new AC installations to ensure compliance with building codes and energy efficiency standards. We handle all necessary permits.
What are the benefits of replacing an old AC unit?
A new energy-efficient AC lowers utility bills, improves cooling performance, reduces noise levels, and enhances indoor air quality. It also prevents costly repairs and increases home resale value.
Can I install an AC unit myself?
AC installation requires electrical connections, refrigerant handling, and ductwork integration, which should be performed by a licensed HVAC professional to ensure efficiency, safety, and warranty coverage.
