Air Conditioning Services — Installation, Maintenance & Repairs in the GTA

Stay cool and comfortable all summer with Aurora Star Tech’s professional air conditioning services. From central AC installation to emergency repairs and annual tune-ups, our certified cooling technicians are ready to serve homeowners and businesses across the Greater Toronto Area.

Air Conditioning Installation

Whether you’re installing AC for the first time or upgrading an outdated system, Aurora Star Tech handles it all. Our technicians assess your space, recommend the right equipment for your home’s size and layout, and complete a clean, code-compliant installation — including electrical connections, refrigerant charging, and full system commissioning.

We work with all major AC brands including Carrier, Lennox, Trane, Goodman, Daikin, and more. We carry both central air conditioners and ductless mini-split systems to suit any home configuration.

Central Air Conditioners

Ideal for homes with existing ductwork. Central AC provides whole-home cooling through your existing forced-air system. We install high-efficiency models (up to 22 SEER) that keep you cool while keeping energy costs down.

Ductless Mini-Split AC

No ductwork? No problem. Ductless mini-split systems are perfect for additions, older homes, or targeted room cooling. They’re quiet, efficient, and can provide both cooling and heating year-round.

Air Conditioning Maintenance

Annual AC maintenance keeps your system running at peak efficiency and prevents breakdowns during the hottest days of summer. Our seasonal tune-up includes:

• Air filter inspection and replacement
• Condenser and evaporator coil cleaning
• Refrigerant level check and recharge if needed
• Thermostat calibration and testing
• Electrical connections and capacitor inspection
• Drainage line flush to prevent water damage
• Full system performance test and efficiency report

Air Conditioning Repair

Is your AC not cooling, blowing warm air, leaking water, making strange noises, or not turning on at all? Our experienced technicians quickly diagnose and repair all AC problems. Common repairs we handle include:

• Refrigerant leak detection and recharge
• Compressor and capacitor replacement
• Condenser fan motor repair
• Frozen evaporator coil issues
• Thermostat and control board problems
• Drainage and condensate pump issues

AC System Upgrades & Replacements

If your air conditioner is over 10–12 years old or requiring frequent repairs, upgrading to a modern high-efficiency system can save you significantly on energy bills. We handle old unit removal, new equipment installation, and full system testing — all in one visit.

Frequently Asked Questions

How often should my AC be serviced?

We recommend annual air conditioner maintenance — ideally in the spring before cooling season. Regular service keeps your system running efficiently, extends its lifespan, and helps you avoid expensive mid-summer breakdowns.

What are signs my AC needs repair?

Common warning signs include warm air blowing from vents, weak airflow, unusual noises (grinding, squealing, banging), water leaking around the unit, strange odours, or a sudden spike in your electricity bill. If you notice any of these, give us a call.

How long does an air conditioner last?

A well-maintained central air conditioner typically lasts 12–15 years. If yours is approaching that age and requiring more frequent repairs, it’s usually more cost-effective to replace it with a newer, more efficient model.

What size AC do I need for my home?

The right AC size depends on your home’s square footage, insulation, window coverage, and other factors. Our technicians perform a proper load calculation to recommend the correctly sized unit — avoiding the common mistake of over-sizing or under-sizing.
