Scarborough AC Experts
Expert Air Conditioning Installation, Done Right Since 1999
Megacity HVAC has installed air conditioning across Scarborough since 1999, from Agincourt bungalows to Malvern townhouses to West Hill detached homes. Our TSSA-certified technicians size every system with a proper Manual J load calculation: square footage, insulation, ceiling height, and window exposure. A right-sized AC removes humidity as it cools; an oversized one doesn't, and an undersized one runs non-stop.
Central AC starts at $3,500 installed for homes with existing ductwork. For homes without ducts, common in older Scarborough builds, a ductless mini-split avoids the $5,000–$10,000 cost of adding new duct runs and starts from $3,000 for a single zone. We are an Authorized Lennox Dealer and install Fujitsu, York, Goodman, Daikin, and Mitsubishi. Every installation includes a manufacturer warranty and our workmanship guarantee.

What to Expect From an AC Installation
1
In-Home Assessment
We assess your home (square footage, insulation, existing ducts, window exposure) and recommend the right system and size.
2
Sizing & System Selection
We run a proper Manual J load calculation. No guesswork: right-sized AC means better comfort, lower bills, and longer equipment life.
3
Professional Installation
TSSA-certified technicians set the outdoor condenser, run refrigerant lines, wire the electrical, and configure your thermostat, usually in a single day.
4
Full System Test
We run a complete cooling cycle, verify the temperature drop across all zones, and walk you through the new system before we leave.
Common Situations
Why Scarborough Homeowners Replace Their AC
Most of these are solved with a properly sized new system installed in a single day.
No Cooling After a Hot Weekend
Older central AC units fail during the first sustained heat wave of the season. If yours is over 12 years old, a replacement is often more cost-effective than another repair.
Install from $3,500
Home Gets Humid but Not Cool
An oversized or poorly sized AC cools too quickly without removing humidity. A proper Manual J calculation and a correctly sized replacement fixes this permanently.
Included with your quote
Some Rooms Always Hot
Uneven cooling in Scarborough homes, especially two-storey or bungalow additions, is usually a ductwork or sizing issue. A ductless mini-split can solve hard-to-reach zones.
From $3,000 (single zone)
No Existing Ductwork
Common in older Scarborough bungalows and townhouse additions. A ductless mini-split installs without cutting into walls: cleaner, faster, and avoids $5,000–$10,000 in duct work.
From $3,000
Rising Hydro Bills Every Summer
A 10-year-old 12 SEER AC can use 25–40% more electricity than a modern 16 SEER2 unit. Upgrading often pays for itself within 4–6 years on Hydro savings alone.
From $3,500 installed
R-22 Refrigerant System
R-22 (Freon) has been phased out in Canada. Recharging is expensive and increasingly scarce. The practical fix is replacement with a modern R-410A or R-454B system.

Common Questions
AC Installation Scarborough: FAQ
How much does AC installation cost in Scarborough?
A central air conditioning installation in Scarborough typically costs between $3,500 and $5,500 depending on the system size, SEER rating, and whether ductwork modifications are needed. Ductless mini-split systems start from $3,000 for a single zone. You get a written quote with detailed pricing at your home, so you know exactly what to expect before we begin.
What is the best SEER rating for a Scarborough home?
For Scarborough homes, we recommend a minimum of 16 SEER for a good balance of efficiency and cost. A 16 SEER unit uses about 25% less energy than the minimum 14 SEER. For maximum efficiency and the lowest cooling bills, consider 18-21 SEER models. Higher SEER units cost more upfront but pay for themselves in 3-5 years through lower Hydro bills, especially with Scarborough summers getting hotter each year.
Should I choose central AC or a ductless system for my Scarborough home?
If your Scarborough home already has ductwork from your furnace, central AC is usually the most cost-effective choice at $3,500-5,500 installed. For homes without ducts, common in older Scarborough bungalows, a ductless mini-split is the better option, avoiding the $5,000-10,000 cost of adding ductwork. We assess your home and recommend the most practical and affordable solution.
How long does an AC installation take?
Most central AC installations in Scarborough are completed in a single day, typically 4 to 8 hours. This includes setting the outdoor condenser, connecting refrigerant lines, electrical wiring, thermostat setup, and full system testing. Ductless mini-split installations for a single zone take 3 to 5 hours. Multi-zone ductless systems may take 1 to 2 days.
