HVAC · AIR CONDITIONING
Central AC done the right way. We install high-efficiency SEER2-rated split systems, ductless mini-split for older Toronto homes without ductwork, and smart thermostats from Ecobee, Nest, and Honeywell. Most AC units in Toronto are oversized — installers guess by square footage, drop in a 4-ton unit, and the system short-cycles all summer. Caspian runs a Manual J load calculation on every install so your system runs long enough to actually pull humidity out of the air.
Whether you're swapping a tired 15-year-old condenser, retrofitting cooling into a hundred-year-old Toronto semi without ducts, or replacing furnace and AC together, Caspian installs every major cooling system — sized with a Manual J calculation and registered for full manufacturer warranty.
Outdoor condenser plus indoor evaporator coil paired with your furnace. Lennox, Carrier, Trane, Goodman, and Daikin — line-set, refrigerant charge, and condensate routing done properly.
Single-zone and multi-zone ductless systems for older Toronto homes, additions, attic conversions, and finished basements where running new ductwork isn't practical or worth it.
Lennox XC25, Carrier Infinity, and other variable-capacity systems that modulate output 25–100%. Quieter, more even temperatures, and dramatically better humidity control.
One outdoor unit, cooling in summer and heat down to -25°C in winter. Pairs with your furnace as a dual-fuel system and qualifies for federal and provincial rebates.
Ecobee, Nest, and Honeywell — supplied, installed, wired correctly (C-wire if needed), and configured against your equipment. No "it works but nothing is automated."
Replacing both at once is almost always cheaper than doing them separately — matched coil and condenser, single install visit, one warranty registration, one rebate filing.
You can buy the most expensive AC on the market and it'll still feel terrible if it's oversized. Here's the part most installers skip.
The most common AC mistake in Toronto isn't picking the wrong brand — it's oversizing. The installer eyeballs your square footage, picks a 4-ton condenser when you actually need 2.5-ton, and the unit is too big for the load from the day it's commissioned.
An oversized AC cools the air quickly but doesn't run long enough to remove humidity. The thermostat hits target in fifteen minutes, the compressor shuts off, and the moisture stays in the air. The house feels cold and clammy at the same time — and damp basements start growing mold.
A properly sized AC runs longer, pulls humidity out as it cools, costs less per hour to operate, and lasts years longer because the compressor isn't starting and stopping every fifteen minutes — start-up is the hardest thing a compressor does.
Caspian runs a Manual J load calculation on every install — accounting for insulation, window U-value, sun exposure (south-facing glass is a huge cooling load), and the latent (humidity) load on top of the sensible (temperature) load. Not square-footage rule-of-thumb. The right answer, every time.
Air conditioners give warnings before they fail completely. Catch them in the spring and you can plan a clean replacement before the first 30°C week — wait, and you'll be sweating it out on the hottest day of the year.
Systems built before 2010 typically run R-22 refrigerant, which is now obsolete — production was phased out under the Montreal Protocol and the remaining stock is effectively unobtainable. A leak is a death sentence.
Ice on the condenser or evaporator coil in summer means refrigerant is low (slow leak) or airflow is restricted (dirty filter, failed blower, blocked return). Both get expensive fast on an aging unit.
One capacitor swap is normal maintenance. Three in two summers means the compressor is drawing too much current — usually because the system is dying and stressing every component upstream.
If your July hydro bill has climbed each year on similar weather, the AC is losing efficiency — coil fouling, refrigerant slowly leaking, compressor wearing out. A new SEER2 unit will pay for part of itself.
