A faulty igniter or dirty flame sensor prevents a furnace from firing. HVAC Technicians diagnose this system issue on-site and resolve it, in most cases, the same day
Refrigerant loss reduces cooling output and overworks the compressor. Technicians perform system troubleshooting to identify the exact leak source before recharging takes place
A heating system or cooling system that starts and stops without completing a full cycle signals a clogged filter, oversized unit, or failing component. Technicians provide expert recommendations on repair versus replacement to stop recurring breakdowns
A miscalibrated thermostat causes erratic temperature control. Newmarket's rapid seasonal swings expose calibration faults faster than in milder climates — call SmileHVAC for an accurate diagnosis
A dirty filter forces blower motors to overwork and raises energy consumption. Newmarket homes with pets or high dust levels need filter replacement every 60 to 90 days
Aging duct systems reduce heating system efficiency and create uneven temperatures between floors across many established Newmarket neighbourhoods

Newmarket’s climate creates seasonal HVAC challenges that demand attention from Ontario homeowners throughout the year. Reliable heating is a core requirement — furnaces run continuously for five to six months. Humidity control is equally essential: cooling systems must manage elevated moisture each summer alongside temperature reduction.
Key seasonal HVAC demands in Newmarket:
Newmarket’s climate directly impacts system efficiency across all heating and cooling systems. According to Natural Resources Canada, space heating accounts for approximately 64% of energy use in the average Canadian home. In Newmarket, where furnaces run November through March, even a modest efficiency drop adds measurable cost to every gas bill.
Heating systems require specific climate adaptations to perform reliably here. Cooling systems provide summer comfort year after year — when sized and serviced for Newmarket’s humidity loads and the current 14 SEER minimum.
How Newmarket’s climate creates specific demands on every HVAC system:
Commercial HVAC in Newmarket spans a wide range of building types — offices, retail storefronts, and light industrial units. Each presents higher occupancy loads and stricter ventilation requirements than a standard residential home. SmileHVAC serves these clients with the same in-house licensed technicians and transparent First Time Quote pricing used on every residential call.
Business cooling solutions for retail systems and office heating applications require precise unit sizing. An oversized unit running in short cycles wastes energy and accelerates wear — SmileHVAC performs load calculations for commercial spaces before recommending any equipment. Commercial services include multi-zone AC, HRV systems, rooftop unit repair, and furnace installation.
Commercial maintenance keeps equipment running through peak trading periods and reduces the risk of unplanned shutdowns. SmileHVAC offers scheduled servicing for commercial properties in Newmarket, with the same inspection scope applied to every call.
HVAC Maintenance Services are a core preventative offering of SmileHVAC in Newmarket. Regular maintenance directly improves energy efficiency by sustaining rated performance. Heating systems offer measurable energy savings — a furnace maintained at 96% AFUE converts nearly all fuel into usable heat. Cooling systems utilize energy-efficient technology: SmileHVAC installs Lennox ML series air conditioners rated at 14 SEER, and Gree cold-climate heat pumps for dual heating and cooling efficiency.
Newmarket homeowners upgrading equipment in 2026 can apply for the Ontario Home Renovation Savings Program, active through November 2026. Electrically heated homes qualify for up to $7,500 on an air source heat pump and up to $12,000 for a ground source system.
A bi-annual maintenance schedule reduces utility bills and delivers consistent cost-saving results:
SmileHVAC installs, repairs, and maintains both tank and tankless water heaters across Newmarket. Tankless units heat water on demand and eliminate standby losses. Tank models store 40 to 75 gallons for homes with consistent high-volume demand.
One Newmarket homeowner switched from a failing 40-gallon tank to a Navien tankless unit. Hot water delivery became consistent across three bathrooms, and monthly gas usage dropped in the first billing cycle.
Indoor air quality solutions from SmileHVAC include HEPA filtration, humidifier installation, and HRV (Heat Recovery Ventilator) servicing. These solutions reduce airborne allergens and control humidity within the recommended 30% to 50% range, improving respiratory comfort in Newmarket homes.
When repair costs are high relative to system age, SmileHVAC technicians explain both options honestly — without pushing replacement. The service call is effectively free when repair is done: diagnosis costs $120 plus tax and is deducted from the final repair cost. For a simple problem, $120 is the total charge.
Heating and cooling systems here benefit from bi-annual servicing. A spring tune-up prepares cooling equipment; a fall tune-up prepares heating equipment. Preventative maintenance sustains AFUE and SEER ratings and reduces emergency breakdown risk.
Smile HVAC provides furnace repair and installation, central AC and ductless AC service, water heater repair, heat pump installation, HRV service, HEPA filtration, and humidifier installation. Both residential and commercial properties in the area are covered.
Central air conditioner installation in Ontario typically ranges from $3,500 to $6,500 for a standard residential unit. The final cost depends on system size, brand, and ductwork. SmileHVAC provides a written First Time Quote before work begins — and that price does not change after the homeowner accepts it.
Local homeowners can apply for the Ontario Home Renovation Savings Program, active through November 2026. Electrically heated homes qualify for up to $7,500 on a cold-climate air source heat pump. Ground source systems qualify for up to $12,000. SmileHVAC installs eligible Gree heat pump systems and assists with each application.
Smile HVAC technicians hold TSSA certification and carry licences in gas, refrigeration, plumbing, and electrical work. The company is a Google Guaranteed contractor and a Lennox Premier Dealer. All technicians are in-house employees — no subcontractors are dispatched for local service calls.
Gas furnaces last 10 to 15 years with regular maintenance. Central air conditioners average 12 to 15 years. Heat pumps typically run 10 years. Bi-annual servicing in this climate consistently extends system life toward these upper limits.
Smile HVAC provides 24/7 emergency service throughout Newmarket. Furnace failures during cold snaps and AC breakdowns during summer heat events are priority dispatches. The office is available around the clock, including evenings, weekends, and holidays.
Key factors include home square footage, insulation level, duct condition, and the local seasonal temperature range. SmileHVAC performs a room-by-room load calculation before recommending any system. Right-sizing eliminates short cycling and extends equipment lifespan.
Smile HVAC is authorized and licensed to service over 30 brands, so if you own any HVAC equipment from these brands, you don’t need to call two companies. Smile HVAC will help you solve all HVAC-related issues and will assist with repairs and installations. We work with all brands including Lennox, Goodman, Amana, Keeprite, Bryant, Daikin, Carrier, York, Trane, Comfortmaker, Payne, Tempstar, Rheem, Ruud, and Mitsubishi Electric
