HVAC, furnace & hot-water service in Alliston
Alliston combines established neighbourhoods, growing subdivisions, and a strong local employment base. We target furnace reliability, AC performance, heat pumps, and hot-water replacement with clear written scopes.
Online booking is available anytime. We confirm coverage and timing for your address before the visit.
Alliston is the largest settlement in New Tecumseth and continues to grow. Newer subdivisions and older homes can have very different duct sizing, venting, electrical capacity, and equipment ages, so replacement decisions should not be made from square footage alone.
We diagnose furnace and AC problems first, then compare repair, staged furnace, heat-pump, or hybrid options when replacement actually makes sense. Water-heater and tankless work is planned around household demand, gas capacity, venting, and service access.
Alliston is outside our closest daily loop, so we confirm travel and appointment timing before accepting the visit. Planned estimates are often easier to schedule than urgent same-day requests.
Furnace no-heat offer

Ductless heat pumps in Alliston for electric baseboard, propane and wood-heated homes
If your Alliston home has no ductwork or natural gas connection, ask about a cold-climate mini-split or multi-zone heat pump for heating and summer cooling. We assess room layout, heating demand, electrical capacity and backup heat before choosing indoor heads and outdoor equipment.
$1,250 per eligible heating ton, up to $7,500: qualifying purchased cold-climate air-source systems may receive Home Renovation Savings rebates where the existing primary heat is electricity, oil, propane or wood. This is a rebate, not the installation price. No gas connection alone does not establish eligibility; an occasional wood fireplace does not establish your primary heating fuel.
Paperwork handled with our team: we coordinate eligibility review, equipment documentation, the pre-installation application and post-installation submission with you. Required homeowner information and signatures remain necessary. Program pre-approval must be received before installation, and the program administrator determines approval and payment.
We confirm address coverage and timing before booking, including Barrie visits by arrangement. Official heat pump rebate requirements.

Services for Alliston homeowners
- Heating — Furnace and heater installation, high-efficiency changeouts, boilers and hydronics, combustion and venting checks, and winter repair when limits roll or the house will not hold setpoint. We document temperature rise, safety proving, gas pressure where applicable, and filter or static issues that cause nuisance trips — then quote repairs that match what we measured, not guesswork.
- Cooling — Central air installs and changeouts, ductless commissioning, seasonal tune-ups with coil, drain, and capacitor checks, and refrigerant work that starts with leak search and electrical verification — not a quick top-off. We commission for sensible cooling and humidity control on muggy Ontario days, and we flag R-22 end-of-life equipment when patch jobs stop making sense.
- Heat Pumps, Ducted & Ductless — Cold-climate heat pumps and ductless systems sized, commissioned, and supported for Ontario winters.
- Water Treatment — Whole-home water filtration, water softeners, reverse osmosis systems (RO), drinking water filtration, and water treatment replacement and service. Authorized Excalibur Water Systems Dealer in Canada.
- Gas Fireplace — Gas fireplace repair, maintenance, ignition and pilot troubleshooting, fan and control service, venting and gas checks, replacement, and new installation.
- Water Heaters & Tankless — Tankless, power vent, natural draft and heat pump water heater installation, replacement and service. Authorized Rinnai Dealer, also servicing Rheem and Bradford White systems.
- Commercial & light commercial — Rooftops, tenant fit-ups, planned maintenance, and sheet metal when the catalog doesn’t fit.
- Boiler, radiant floor heating & snow melting — Boiler installation, repair, and hydronic system upgrades, radiant floor heating for basements and renovations, and heated driveways or walkways that melt snow automatically.
- Attic insulation — Attic insulation estimates and home-comfort upgrades across York Region. Any Home Renovation Savings rebate depends on homeowner eligibility and use of an approved participating contractor.
- Whole-home humidifiers — Furnace-mounted humidifier installation, repair, and maintenance so winter heating season doesn't mean dry skin, static shocks, and cracking hardwood.
