North York AC Services
Professional Air Conditioning Installation — Done Right Since 1999
Megacity HVAC has been installing central AC and ductless mini-splits across North York since 1999. Whether you have a 1950s bungalow in Don Mills with no existing ductwork or a larger Bayview Village home with a multi-zone cooling challenge, our TSSA-certified technicians start every project with a proper Manual J load calculation — the only honest way to size an air conditioner.
As an Authorized Lennox Dealer we also install Carrier, Trane, York, Daikin, Mitsubishi Electric, and KeepRite. Central AC runs $3,500–$5,500 installed for most North York homes with existing ductwork. Ductless mini-splits start at $3,000 for a single zone. $0-down Enbridge Sustain financing is available on qualifying equipment.

Our Process
What to Expect From an AC Installation
1
Free In-Home Assessment
We visit, measure your home, inspect existing ductwork, and perform a Manual J load calculation to size the system correctly.
2
Clear Written Quote
You get a fixed price with equipment details, installation scope, and warranty terms — before a single bolt turns.
3
Same-Week Installation
Our crew handles everything: removal of the old unit, new equipment set, refrigerant line connection, electrical, and thermostat wiring.
4
Commission and Test
We run a full cooling cycle, verify the temperature drop across the coil, check refrigerant charge, and walk you through the system.
Common Situations
North York Cooling Challenges We Solve
Most installations are completed the same week you approve the quote.
Aging System (10+ Years)
North York homes with original 1990s–2000s central AC pay 25–40% more in electricity than a modern 14 SEER2 unit. We assess replacement vs. repair honestly.
Replace from $3,500
No Existing Ductwork
Older Don Mills bungalows and Willowdale split-levels without central ductwork are ideal candidates for ductless mini-splits — no major renovation required.
From $3,000 (single zone)
Uneven Cooling Between Floors
A common complaint in North York two-storey homes. Often caused by an incorrectly sized unit, poor duct balance, or a single-zone system where two zones are needed.
Zoning from $4,500
AC Short Cycling
The system starts and stops without completing a full cycle — almost always an oversized unit installed without a load calculation. Right-sizing solves it for good.
Replace from $3,500
Refrigerant (R-22) System
R-22 (Freon) has been phased out. Recharging costs $80–$150 per pound, and leaks are common on older systems. Replacement now is the most cost-effective path.
Replace from $3,500
High Humidity Indoors
An oversized AC cools too fast without running long enough to remove humidity. Proper sizing and a variable-speed unit solve the clammy-house problem.

Common Questions
AC Installation North York — FAQ
How much does a new AC cost in North York?
Central air conditioning installation in North York ranges from $3,500 to $5,500 depending on the system capacity, SEER rating, and any ductwork modifications required. Ductless mini-split systems start at $3,000 for a single zone. Multi-zone ductless setups for larger North York homes run $6,000 to $12,000 depending on the number of zones. We provide free in-home estimates with transparent pricing.
What size AC unit do I need for my North York home?
AC sizing depends on your home square footage, insulation, window count and exposure, ceiling height, and number of floors. A typical 1,500 sq ft North York home needs a 2.5 to 3 ton unit. Oversizing causes short cycling and poor humidity removal. Undersizing means the system runs constantly without reaching your target temperature. Our technicians perform a proper Manual J load calculation during the free estimate to determine the right size.
Central AC or ductless — which is better for North York?
If your North York home has existing ductwork from your furnace, central AC is typically the most cost-effective option at $3,500–5,500. For homes without ductwork, additions, or rooms your central system cannot reach, ductless mini-splits offer targeted cooling without the cost of new ductwork. Many North York homeowners use a combination — central AC for the main areas and a ductless unit for a finished basement or above-garage room.
Do you offer AC repair service in North York?
Yes. We provide 24/7 emergency AC repair across all North York neighbourhoods. Common issues we fix include refrigerant leaks, compressor failures, frozen evaporator coils, electrical problems, and thermostat issues. Most AC repairs cost between $150 and $600. We carry common parts on our trucks and complete most repairs same-day. Call us at (416) 286-5665 for immediate service.
