Central AC Installation in Pickering

Manual J load calc. Rule-of-thumb 1 ton per 600 sq ft is OK as a sanity check but not for ordering. Oversized AC short-cycles, doesn't dehumidify, and wears out faster. Most Pickering 1,500-2,500 sq ft homes are properly sized at 3 ton; 2,500-3,500 sq ft at 4 ton; 3,500+ at 5 ton.

R-410A is being phased out. New systems use R-454B (mildly flammable, A2L class) or R-32. They are NOT drop-in compatible with R-410A — the new condenser and coil must be paired. Old R-410A systems can still be serviced and recharged through 2030 under EPA / Ontario phase-down rules; we'll quote both options if you have a partial-replace scenario.

Yes if the furnace is < 12 years old and the blower CFM matches the AC tonnage. Manual J + Manual D checks airflow. R-454B AC pairs with any modern furnace. If furnace is also at end-of-life we bundle replacement — saves $1,000-$2,000 vs separate installs.

1 day for like-for-like swap (8-10 hours). 1.5 days if new lineset run through finished walls. 2 days if 240V circuit must be added to electrical panel (involves ESA inspection scheduling).

Recovered by ODP-certified tech per Ontario Reg 463/10. Paperwork (refrigerant recovery log) delivered at close-out. We do NOT vent refrigerant under any circumstances — illegal and bad for the atmosphere.

Premium tier (Lennox XC25, Carrier Infinity 24) runs 55-62 dBA at the condenser — quieter than normal conversation. Workhorse 2-stage (Trane XR17, Bryant 187B) 65-72 dBA. Standard single-stage 72-78 dBA. Placement matters — we measure setback from bedrooms / patios pre-contract.

Yes. Salt-air spray from Lake Ontario corrodes copper coils 30-50% faster within 1.5 km of the shoreline (Etobicoke south, Long Branch, Beach Strip, downtown waterfront). We use factory-coated coils (Microban, Insulink) or aftermarket Heresite coating for +$280-$450 — adds 5-7 years to coil life.

Federal mandate effective Jan 1, 2023: 14.3 SEER2 minimum (≈ 15 SEER old rating) for new residential AC installs in Ontario. We default to 16+ SEER2 — the cost difference vs the mandate minimum is recovered in 3-4 years on Pickering Hydro rates ($0.14-$0.18/kWh 2026 forecast).

12-18 years typical lifespan in Pickering climate. Premium tier (Lennox / Carrier) often 18-22 years with annual servicing. Workhorse tier 12-16 years. Filter changes every 1-3 months + annual coil cleaning are the difference between 12 years and 18 years.

Yes — AC install doesn't trigger Enbridge gas restrictions. ESA inspections may have minor scheduling delays in mid-June through July if downtown core. We pre-book inspection slots at contract signing to avoid issues.
