What does central ac installation typically cost in New Brunswick?

Central air conditioning installation in New Brunswick typically ranges from $3,500-$8,000+ depending on your home's size, existing ductwork, and equipment choice. For a standard 1,500-2,000 sq ft home with existing furnace ductwork, expect $4,500-$6,500 including a quality 2.5-3 ton unit, installation, and electrical connections.

Equipment and sizing drive the biggest cost differences. Basic 13-14 SEER units start around $2,200-$3,200 for the outdoor condenser and indoor coil, while high-efficiency 16+ SEER models with variable speed compressors run $3,800-$6,000+. Your contractor will calculate the proper tonnage based on your home's square footage, insulation levels, and window exposure — oversizing wastes energy and money while undersizing leaves you uncomfortable during New Brunswick's humid summers.

Ductwork modifications significantly impact pricing. Homes with existing forced-air heating (oil or gas furnace) typically need minimal ductwork changes, keeping costs lower. However, many older New Brunswick homes have undersized return air ducts that require upgrading for proper AC airflow. Adding new ductwork to baseboard-heated homes jumps costs to $8,000-$15,000+ depending on accessibility and layout complexity.

Installation requirements add $800-$1,500 to the base equipment cost. This covers the refrigerant lines (often requiring new holes through foundation walls), electrical connections, condensate drain, outdoor pad, and system commissioning. Your electrical contractor will need to install a dedicated 240V circuit — budget an additional $300-$600 for this work. NB Power requires an electrical permit for this installation, and TIS inspection is mandatory.

Consider New Brunswick's climate when choosing equipment. Our summers are typically humid but not extremely hot compared to central Canada, so a properly-sized 14-16 SEER unit often provides excellent comfort without the premium cost of ultra-high-efficiency models. However, if you're planning other energy upgrades, higher-efficiency AC may qualify for NB Power rebates.

Get quotes from at least three licensed HVAC contractors who can assess your specific home and ductwork. Verify their TIS gas licence if they're connecting to existing gas furnace controls, and confirm they'll pull proper electrical permits. Most installations take 1-2 days once equipment arrives, but summer is peak season — book early for best scheduling and pricing.
