Air Conditioning Repair & Installation in North York
When your AC stops working in a North York summer, you need a technician who shows up the same day with the right parts. Megacity HVAC delivers — TSSA-certified, upfront pricing, and 27 years of experience.
Dependable Air Conditioning Service for North York Homes
North York covers a vast area with an enormous variety of housing, from the mature tree-lined streets of Willowdale and Bayview Village to the newer developments around Yonge and Sheppard, the established family homes of Don Mills and Lansing, and the suburban communities of Newtonbrook and Bathurst Manor. Each neighbourhood has its own mix of home ages, styles, and HVAC configurations — and Megacity HVAC has been servicing all of them since 1999.
Many North York homes were built during the suburban expansion of the 1960s through 1980s. These homes typically have forced-air heating systems with ductwork, making central AC installation straightforward when the existing ducts are in good condition. However, we frequently find that original ductwork in these homes has deteriorated — joints have separated, insulation has compressed, and the ducts were sized for older, less powerful equipment. Our technicians assess your ductwork condition as part of every AC installation to ensure proper airflow and efficiency.
For AC repairs, our trucks are stocked with parts for all major brands. Whether your home has a Lennox, Carrier, Trane, Goodman, Rheem, or any other brand, we can diagnose the issue and complete the repair on the same visit in most cases. Common summer repairs include capacitor replacement, refrigerant recharge, fan motor replacement, and condenser coil cleaning — all of which we handle quickly so you are not without cooling for long.
North York is also home to a growing number of condos and townhomes, many of which benefit from ductless mini-split systems. These units provide efficient cooling and heating with individual zone control, and they install with minimal disruption. For homeowners adding a basement apartment, converting an attic, or dealing with a room that the central system simply cannot keep cool, a ductless unit is often the most practical and cost-effective solution.
We are an Authorized Lennox Dealer and a certified Enbridge Sustain Trusted Partner. This means competitive pricing on premium equipment and full rebate processing on your behalf, so you save as much as possible on a new AC system.

Common AC Problems in North York Homes
We diagnose and repair these issues daily across Willowdale, Don Mills, Bayview Village, and every other North York neighbourhood.
AC Not Cooling
Low refrigerant, dirty condenser coils, failing compressor, or a frozen evaporator coil. In North York, outdoor units surrounded by landscaping accumulate leaves and debris that block airflow and reduce cooling performance.
AC Blowing Warm Air
Refrigerant leak, compressor failure, thermostat misconfiguration, or restricted airflow from a clogged filter. A common call in North York during the first heat wave of the season when systems have sat idle since fall.
Water Leaking from AC
Clogged condensate drain, frozen evaporator coil, or a cracked drain pan. North York homes with finished basements are at particular risk — a leaking AC can cause water damage to ceilings and floors below.
AC Short Cycling
The unit turns on and off rapidly. Usually caused by an oversized system, dirty filter, low refrigerant, or electrical issues. Wastes energy and puts extra strain on the compressor, shortening the system lifespan.
Strange AC Noises
Grinding, squealing, buzzing, or rattling from the indoor or outdoor unit. Typically a failing fan motor, loose components, or compressor starting to fail. Addressing noise early prevents complete breakdown in the middle of summer.
Uneven Cooling Upstairs
The main floor is comfortable but the second floor is too warm. Extremely common in two-storey North York homes with single-zone systems. Solutions include ductwork balancing, zoning dampers, or a supplemental ductless unit.

How much does AC repair cost in North York?
AC repair in North York typically costs between $150 and $600 depending on the issue. Straightforward repairs such as capacitor or contactor replacement, thermostat recalibration, or condensate drain clearing run $150 to $300. More involved work like compressor service, refrigerant leak repair, or evaporator coil replacement falls between $300 and $600. We provide upfront pricing after diagnosis — you know the cost before we start.
Do you provide same-day AC repair in North York?
Yes. We offer same-day AC repair across all North York neighbourhoods including Willowdale, Don Mills, Bayview Village, Newtonbrook, Lansing, and York Mills. During peak summer months we prioritize emergency calls where there is no cooling at all. Call (416) 286-5665 and a TSSA-certified technician can be at your door within hours.
What size AC unit do I need for my North York home?
It depends on your home square footage, insulation, window exposure, and number of floors. Many North York homes range from 1,200 to 2,500 square feet, typically requiring 2.5 to 3.5 ton AC units. We perform a proper Manual J load calculation during our free in-home estimate rather than guessing. Oversized units short-cycle and leave your home clammy; undersized units run constantly without reaching comfort.
Should I repair or replace my North York home AC?
Consider replacement if your AC is over 10 years old, uses R-22 Freon (now banned), needs repairs exceeding half the cost of a new unit, or your electricity bills keep climbing. A new 16 SEER central AC costs $3,500 to $5,500 installed and uses about 25 percent less electricity than older models. For many North York homeowners, the energy savings and avoided repair costs make replacement the smarter long-term investment.
Is a ductless mini-split good for North York condos and townhomes?
Ductless mini-splits are an excellent choice for North York condos, townhomes, and homes without existing ductwork. They provide both cooling and heating, offer zone-by-zone temperature control, and install with minimal disruption — just a small hole through the wall for the refrigerant line. Single-zone systems start at $3,000 installed. They are also popular for home additions or finished basements that the central system cannot reach.
