Air Conditioning Installation Quebec — CMMTQ Certified

An air conditioner only cools. A heat pump cools in summer and heats in winter, making it a versatile two-in-one system. For Quebec with its cold winters, a heat pump is often a better investment.

A wall-mounted (mini-split) AC is ideal for homes without ductwork: quieter, more efficient, and easier to install. Central systems suit homes with existing ducts. BTU size depends on the area to be cooled.

Common causes include a clogged filter, low refrigerant, dirty coils, or a failing compressor. Annual maintenance prevents most issues. For breakdowns, call a CMMTQ-certified technician.

General guideline: 5,000-6,000 BTU for 150-300 sq ft, 9,000-12,000 BTU for 350-500 sq ft, 18,000 BTU for 700-1,000 sq ft. These figures vary with sun exposure, insulation, and number of occupants.

Central AC units last 15-20 years, wall-mounted units 10-15 years. If the unit is over 10 years old and needs major repairs, replacement is often more cost-effective. Modern units are significantly more energy-efficient.

Standard air conditioners alone are generally not subsidized. However, if you opt for a heat pump (which includes cooling), you may qualify for Hydro-Quebec and Renoclimat programs offering up to $5,000 in rebates.
