Complete Air Conditioning Solutions for GTA & Durham Homes
An oversized air conditioner cools the air temperature quickly but doesn't run long enough to remove humidity — leaving homes that feel cold and clammy rather than genuinely comfortable. An undersized unit runs continuously and can't keep up during GTA heat waves. Every Malek AC installation begins with a Manual J cooling load calculation to eliminate both problems.
Lennox AC Systems We Install
Lennox XC17 — Reliable Entry-Level
XC17 · Up to 17 SEER2 · Single-Stage
Meets Ontario high-efficiency standards. Strong upgrade over pre-2010 equipment. Cost-effective for budget-conscious replacements.
Lennox XC21 — Best Value in Comfort
XC21 · Up to 21 SEER2 · Two-Stage
Runs at low capacity (~65%) most of the time — quieter, better dehumidification, more consistent temperatures. The right choice for most GTA homes.
Lennox XC25 — Maximum Efficiency
XC25 · Up to 26 SEER2 · Variable-Capacity
Near-silent at low speed, superior humidity control, highest SEER2 rating in residential central AC. Pairs with Lennox iComfort S30.
AC repair emergencies in July are treated with the same urgency as no-heat calls in January. Our technicians carry the most commonly replaced AC components for single-visit repairs wherever possible.

Common Questions
Frequently Asked Questions
How much does AC installation cost in Ontario?
$3,500–$8,000+ installed depending on SEER2 rating, home size, and whether refrigerant lines or electrical upgrades are needed. A Lennox XC17 in a typical 1,800 sq ft GTA home runs $3,800–$5,000.
Why is my AC running but not cooling?
Three most common causes: failed or weak capacitor, low refrigerant from a leak, or a dirty condenser coil. Each requires a different fix — we diagnose all three before recommending any repair.
How much does AC repair cost?
Diagnostic call: $89–$129. Capacitor or contactor: $150–$350. Refrigerant leak repair and recharge: $400–$900+. Fan motor: $350–$600. We quote before proceeding — no surprise invoices.
Should I repair or replace my AC?
AC under 10 years old with a repair under $800 → repair. AC 12+ years old with a repair over $700 → replacement evaluation. We present both options with honest payback analysis.
What is SEER2?
SEER2 is the 2023 updated seasonal energy efficiency rating for AC systems. Higher SEER2 = less electricity per unit of cooling. A 17 SEER2 unit uses about 35% less electricity than a 13 SEER unit from 2010.
