Reliable Heating & Cooling for Dartmouth Homes

Dartmouth's housing mix runs the full range — character homes in Downtown Dartmouth, established residential neighbourhoods around Lake Banook and Lake Micmac, post-war bungalows in Woodside and Westphal, and growing suburban developments in Cole Harbour, Forest Hills, and Portland Estates. Each home type comes with its own heating and cooling considerations.


Older Dartmouth homes are often still running on oil or electric baseboard heat, where converting to a heat pump can deliver meaningful annual savings. Newer suburban builds typically have forced-air systems that benefit from upgraded heat pumps or central AC. And lakefront properties — beautiful as they are — can have humidity and air quality challenges that the right HRV solves.



We work with all of it. Whether you're upgrading an older home, adding cooling to a newer build, or fixing a system that quit on the coldest morning of the year, Sustainable Heating & Cooling Inc. delivers the right solution — sized correctly, installed cleanly, and backed by Daikin's industry-leading warranties.

Frequently Asked Questions About HVAC in Dartmouth

  • Do you service all of Dartmouth?

    Yes. We service all Dartmouth neighbourhoods, from Downtown Dartmouth and the lake communities to Portland Estates, Forest Hills, Cole Harbour, and Eastern Passage.

  • Can you convert my older Dartmouth home from oil heat to a heat pump?

    Yes. Oil-to-heat-pump conversion is one of our most-requested services for Dartmouth's older homes. We handle the full conversion — system design, installation, and decommissioning of the existing oil equipment.

  • I have a lakefront home with humidity issues — can you help?

    Yes. Lakefront homes around Lake Banook, Lake Micmac, and Morris Lake often deal with elevated humidity. A properly sized HRV or ERV, sometimes paired with a heat pump, manages humidity and improves indoor air quality year-round.

  • Do you install ductless systems in older Dartmouth homes?

    Often, ductless mini-splits are the best solution for older Dartmouth homes without ductwork. Single-zone or whole-home multi-zone setups deliver efficient heating and cooling without major renovation.

  • Are you a Daikin Comfort Pro?

    Yes. We're a certified Daikin Comfort Pro, which gives Dartmouth homeowners access to Daikin's full lineup of high-efficiency systems and industry-leading warranties.


  • Do you offer financing?
