Reliable Air Conditioning Service Across Scarborough
Scarborough summers push air conditioners to their limits. With temperatures regularly climbing past 30 degrees and the humid air rolling in off Lake Ontario making it feel closer to 40, a reliable AC system is essential for every Scarborough household. Whether you are in a detached home in Agincourt, a townhouse in Malvern, a split-level in Dorset Park, or a bungalow in West Hill, Megacity HVAC has the experience and parts to get your cooling system working again — usually the same day you call.
Scarborough's housing stock is diverse, and so are the air conditioning systems we service here. Much of Scarborough was developed between the 1950s and 1980s, which means a wide range of home styles and HVAC configurations. The 1960s and 1970s split-levels and raised bungalows that are common throughout neighbourhoods like Woburn, Dorset Park, and Scarborough Village often have older ductwork that was sized for a different era of equipment. We know how to work with these systems — repairing existing units or upgrading to modern, properly sized equipment that actually keeps the whole house comfortable.
For AC repairs, our technicians carry the most common parts on every service truck: capacitors, contactors, fan motors, refrigerant, thermostats, and more. This means most Scarborough AC repairs are completed on the first visit, without the delay of ordering parts and scheduling a return trip. We diagnose the problem, provide a clear price, and fix it — typically within one to two hours.
When repair is no longer the best investment — usually when a unit is over 10 years old, uses the discontinued R-22 refrigerant, or needs repairs costing more than half the price of a replacement — we help Scarborough homeowners upgrade to a modern, energy-efficient system. We install central air conditioning and ductless mini-split systems from Lennox, Carrier, Trane, Ducane, and Daikin. As an Authorized Lennox Dealer, we offer competitive pricing and extended warranty coverage on one of the most trusted names in the industry.
Every installation includes a proper load calculation to ensure the right-sized unit for your Scarborough home. We also handle all Enbridge rebate paperwork as a certified Sustain Trusted Partner, so you get every rebate dollar available without the hassle.

Common AC Problems in Scarborough Homes
We diagnose and repair these issues daily during the cooling season across Agincourt, Malvern, West Hill, and every other Scarborough neighbourhood.
AC Not Cooling
Low refrigerant charge, dirty condenser coils, a failing compressor, or a frozen evaporator coil. Common in Scarborough homes where outdoor units sit near gardens and accumulate debris through spring and summer.
AC Blowing Warm Air
Refrigerant leak, compressor issues, thermostat misconfiguration, or a clogged air filter restricting airflow over the evaporator coil. We check every component during our diagnostic.
Water Leaking from AC
Clogged condensate drain line, frozen evaporator coil, or a cracked drain pan. Particularly common in older Scarborough homes where drain lines have accumulated buildup over years of use.
AC Short Cycling
The unit turns on and off rapidly without completing a cooling cycle. Usually caused by an oversized unit, dirty filter, low refrigerant, or an electrical issue. Common when a previous installer put in the wrong size for the home.
Strange AC Noises
Grinding, squealing, buzzing, or banging from the indoor or outdoor unit. Typically a failing fan motor, loose components, or compressor problems. Early diagnosis prevents a small issue from becoming a full replacement.
High Electricity Bills
If your hydro bill spikes every summer despite normal usage, your AC is losing efficiency. Older units in Scarborough homes running at 8 to 10 SEER use nearly twice the electricity of a modern 16 SEER system.
Central Air vs Ductless: Which Is Right for Your Scarborough Home?
The right cooling system depends on your home's existing ductwork, your budget, and how you use your space. We help you choose during a free in-home assessment.

How much does AC repair cost in Scarborough?
AC repair in Scarborough typically costs between $150 and $600 depending on the issue. Simple fixes like capacitor replacement, thermostat recalibration, or condensate drain clearing run $150 to $250. More involved repairs such as compressor work, refrigerant leak repair, or evaporator coil replacement range from $300 to $600. We provide upfront pricing after diagnosis — no surprises. Our diagnostic fee is applied to the repair cost if you proceed.
Do you offer same-day AC repair in Scarborough?
Yes. We provide same-day AC repair across all Scarborough neighbourhoods including Agincourt, Malvern, West Hill, Rouge, Highland Creek, Birch Cliff, and Scarborough Village. During peak summer months, we prioritize emergency calls where there is no cooling at all. Call (416) 286-5665 and we dispatch a TSSA-certified technician to your home, often within a few hours.
Should I repair or replace my Scarborough home AC?
Consider replacement if your AC unit is over 10 years old, uses R-22 refrigerant (now banned and expensive to source), needs repairs costing more than half the price of a new system, or if your electricity bills keep climbing each summer. A new 16 SEER central AC costs $3,500 to $5,500 installed. For many Scarborough homeowners with aging units, a new system pays for itself within a few years through lower energy costs and avoided repair bills.
What size AC do I need for my Scarborough home?
AC sizing depends on your home square footage, insulation quality, window exposure, ceiling height, and number of floors. Most Scarborough bungalows (1,000 to 1,400 sq ft) need a 2 to 2.5 ton unit. Larger two-storey homes (1,800 to 2,500 sq ft) typically require 3 to 3.5 tons. We perform a proper Manual J load calculation during our free in-home estimate to size your system correctly. An improperly sized unit wastes energy and fails to keep your home comfortable.
Is a ductless mini-split a good option for older Scarborough homes?
Absolutely. Many Scarborough homes built in the 1960s and 1970s either lack ductwork entirely or have undersized ducts that restrict airflow. A ductless mini-split provides efficient cooling and heating without the cost of installing new ductwork, which can run $5,000 to $10,000 on its own. Single-zone ductless systems start at $3,000 installed, and multi-zone systems can cool two to five rooms from one outdoor unit.
