All Heating & Cooling
AC installation that starts with a load calculation, not a guess
An oversized air conditioner short-cycles and leaves your home clammy; an undersized one runs constantly and still can't keep up on a humid July afternoon. We size before we install.

What proper AC installation actually requires
A central air installation is more than setting an outdoor unit on a pad. Refrigerant line sizing, airflow across the existing duct system, and electrical capacity all determine whether the unit performs at its rated efficiency.
Heat gain calculation
We calculate cooling load from window orientation, insulation levels, and square footage rather than sizing off the old unit's tonnage, which is often wrong to begin with.
Duct compatibility check
Many GTA homes have ductwork sized for heating airflow only. We verify the existing supply and return can actually move the air volume a new system requires.
Refrigerant line and electrical review
Line set length, insulation, and breaker capacity all affect long-term reliability and are checked before installation day, not discovered during it.
Outdoor unit placement
Clearance from fences, decks, and snow load off the roofline all factor into where the condenser goes — a poor placement causes airflow restriction that shortens equipment life.
Humid Toronto summers expose sizing mistakes fast
The GTA's summer humidity means an oversized air conditioner cools the air quickly but shuts off before it has run long enough to pull moisture out of it — leaving the house cold but clammy. Homeowners often respond by lowering the thermostat further, which only makes the short-cycling worse and increases wear on the compressor.
Correct sizing solves the humidity problem at the source
A properly sized system runs longer cycles at a lower capacity, which is exactly what removes humidity effectively. We size for both temperature and moisture removal, and where duct limitations exist, we address those directly instead of oversizing the equipment to compensate.

AC installation questions
How long does a central air installation take?
Most single-system installations are completed in a single day, though homes needing duct modifications may take longer.
Will my existing ductwork work with a new AC unit?
In many cases yes, but we verify airflow capacity first — some older GTA homes need supply or return modifications to support a new system properly.
What size air conditioner do I need?
That depends on square footage, insulation, window exposure, and duct capacity. We calculate this rather than estimate it.
Do you handle the electrical work for a new AC unit?
Yes, our licensed technicians handle the disconnect and circuit work required for a new installation.
Can you install a heat pump instead of a standard AC?
Yes, we install cold-climate heat pumps as an alternative, which provide both cooling and supplemental heating.
