HVAC work in Newmarket — including furnace replacements, central air installations, heat pump conversions, and ductwork alterations — requires building permits from the Town of Newmarket Building Services when the work involves structural, gas, or electrical changes. Gas furnace and boiler work requires a TSSA permit and must be performed by a TSSA-licensed gas contractor; Enbridge Gas distributes natural gas throughout Newmarket and is the distributor for any gas service changes or meter modifications. Electrical work associated with HVAC installations — new 240V circuits for heat pumps, upgraded panels for higher-load equipment — requires an ESA permit within Alectra Utilities' distribution territory. Newmarket's geographic position in York Region shapes its HVAC context: the town sits at the southern edge of Lake Simcoe's watershed, and northern Newmarket neighbourhoods can experience more prolonged cold snaps and greater wind exposure from the Lake Simcoe basin than sheltered central areas; Stonehaven and northern Glenway properties are more exposed to prevailing northwest winter winds than downtown Newmarket locations. Historic downtown and Main Street homes from the early twentieth century often have original gravity-duct or steam radiator systems that require full duct replacement or conversion when transitioning to modern forced-air equipment — a significantly larger scope than a straightforward furnace swap in a 1990s home. Gorham College Manor and Huron Heights homes from the late 1960s through the 1980s have basic forced-air systems sized for older equipment and are prime candidates for high-efficiency upgrades. We'll connect you with three licensed Newmarket HVAC contractors.

How to Hire an HVAC Contractor in Newmarket

  1. Describe your HVAC project

    Tell us whether you need a furnace replacement, heat pump installation, AC system, ductwork repair, or other work — plus your Newmarket neighbourhood or FSA (L3X or L3Y), your current system type, and whether your home has existing ductwork.

  2. Receive three matched quotes

    Within 24 hours, three licensed Newmarket HVAC contractors will contact you with quotes that include equipment, installation, and applicable permits.

  3. Verify TSSA licence, WSIB, and equipment specs

    Confirm each contractor's TSSA gas licence number (for gas work), WSIB clearance, and the specific equipment model and AHRI efficiency rating. Ask about applicable Enbridge HER+ rebates and Canada Greener Homes grants for the quoted equipment.

  4. Confirm permit responsibility and utility coordination

    Your contractor must pull all required TSSA, ESA, and Town of Newmarket building permits before work begins. For Alectra service upgrades related to heat pump installations, confirm the contractor will coordinate the ESA and Alectra inspection process. Get permit responsibility and equipment warranty in writing.

Frequently Asked Questions

Do HVAC installations in Newmarket need a permit?

Gas furnace and boiler work requires a TSSA permit in Newmarket regardless of scope. Town of Newmarket building permits are required when the work involves structural changes, new penetrations, or associated electrical panel upgrades. ESA permits are required for new 240V circuits added for heat pumps or air conditioning equipment. Your licensed HVAC contractor should identify which permits apply to your specific project and pull them before work begins.

Is a heat pump a good choice for a Newmarket home?

Yes, for most of Newmarket. Modern cold-climate heat pumps operate effectively to -25°C or lower. Northern Newmarket areas — Stonehaven, northern Glenway, and areas closer to the Lake Simcoe watershed — experience more wind exposure and prolonged cold periods than central Newmarket; ask your contractor to size the heat pump for the actual design temperature at your address. A dual-fuel setup combining a cold-climate heat pump with a gas backup furnace is a common choice for exposed northern lots.

Are there rebates for HVAC upgrades in Newmarket?

Yes. Enbridge Gas's HER+ program offers rebates for eligible high-efficiency furnaces, boilers, and heat pumps for natural gas customers in Newmarket. The federal Canada Greener Homes program has offered grants for heat pump installations. Alectra Utilities periodically runs efficiency incentive programs for electric heating equipment. Confirm current program availability and eligible equipment with your contractor at time of quote, as rebate programs change from year to year.

What should I look for in a Newmarket HVAC contractor?

Verify a TSSA Gas Technician G1 or G2 licence for gas work, active WSIB clearance, and a minimum $2M general liability policy. For heat pump installs, ask for manufacturer certification and experience with cold-climate performance specifications. For older Main Street or Gorham Manor homes with original ductwork, ask for a duct assessment as part of the quote — undersized or deteriorated ducts significantly reduce new system efficiency and must be addressed before modern equipment is installed.
