Keep Cool With East York's Local AC Team
Toronto summers are getting hotter. July and August regularly hit the mid-30s with humidity pushing the feels-like temperature past 40 degrees. For East York homeowners — especially those in older homes that absorb and trap heat — a working air conditioner isn't optional.
Megacity HVAC has been providing air conditioning repair, installation, and maintenance in East York since 1999. Our shop is at 885 O'Connor Dr, which means when your AC fails, we don't have to cross the city to help. Our technicians are often already in the neighbourhood, and we offer same-day repair service for East York residents. We carry common AC parts on our trucks so most repairs are completed on the first visit.
East York's housing stock creates specific air conditioning challenges that we've spent 27 years learning to solve. Many homes here were built in the 1940s through 1960s — some with ductwork that can handle central air, and some without. For homes with existing ducts, adding a central AC system is straightforward and cost-effective. For homes without ductwork, a ductless mini-split system provides efficient cooling (and heating) without tearing open walls and ceilings.
We install central air conditioning systems from Lennox, Carrier, Trane, Ducane, and Daikin. We're an Authorized Lennox Dealer, which means extended warranty coverage and competitive pricing on one of the most reliable brands in the industry. For ductless systems, we install single-zone and multi-zone mini-splits that let you cool specific rooms independently — particularly useful for East York homes where the upstairs bedroom gets significantly hotter than the main floor.
All our AC installations come with a thorough load calculation to ensure the unit is properly sized for your home. An oversized AC cools unevenly, short-cycles, and wastes energy. An undersized unit runs constantly without reaching the set temperature. We size it right the first time — that's why our customers stay with us for years.

Common AC Problems in East York Homes
We diagnose and repair these issues daily during the cooling season. Most repairs are completed on the first visit with parts we carry on our trucks.
AC Not Cooling
Low refrigerant, dirty condenser coils, a failing compressor, or a frozen evaporator coil. Often caused by neglected maintenance — especially in East York homes that run AC hard during July and August.
AC Blowing Warm Air
Thermostat settings, refrigerant leak, compressor issues, or a dirty air filter restricting airflow. We check all of these during our diagnostic visit.
Water Leaking from AC
Clogged condensate drain line, frozen evaporator coil, or a cracked drain pan. Common in older East York homes where condensate lines have accumulated buildup over the years.
AC Short Cycling
The unit turns on and off rapidly. Usually caused by an oversized unit, dirty filter, low refrigerant, or an electrical issue. Oversized AC is common when the wrong size was installed during a previous replacement.
Strange AC Noises
Grinding, squealing, buzzing, or banging sounds from your AC typically indicate a failing fan motor, loose components, or compressor problems. Don't ignore these — early repair prevents larger failures.
AC Running Constantly
Your unit never seems to shut off. Could be an undersized system, poor insulation (common in older East York homes), dirty coils, or low refrigerant. This drives up your electricity bill significantly.

AC Repair East York — FAQ
How much does AC installation cost in East York?
Central air conditioning installation in East York typically costs $3,500 to $6,500 for a standard system, depending on the unit size, SEER rating, and whether your home needs ductwork modifications. Ductless mini-split systems start at $3,000 to $4,500 for a single zone. For older East York homes without existing ductwork, a ductless system is often the most cost-effective option. We provide free in-home estimates with transparent pricing.
Should I get central air or ductless for my older East York home?
It depends on your home. If your house already has ductwork from your furnace, central air is usually the most efficient and cost-effective choice — we connect the AC to your existing duct system. If your home lacks ductwork (some older East York homes were built with hot water radiators), a ductless mini-split system avoids the cost and disruption of installing new ducts. We assess both options during a free in-home estimate and recommend what makes the most sense for your specific home.
Should I repair or replace my AC unit?
Consider replacement if your AC is over 10 years old, uses R-22 refrigerant (Freon, which is now banned), needs repairs costing more than half the price of a new unit, or your cooling bills keep rising. Modern units with 16+ SEER ratings use significantly less energy than older models. We provide honest assessments — if a $200 repair will keep your unit running for several more years, we'll tell you.
How long does AC installation take in East York?
A standard central AC installation is completed in one day, typically 4 to 8 hours. If your home needs ductwork modifications or a new ductless system installation, it may take an additional half day. We always provide a time estimate before starting and work efficiently to minimize disruption. Our crews clean up completely when finished.
