Certified HVAC Technicians
Rexdale sits in northwest Toronto, where winters drop below -15°C and humid summers push cooling systems past 30°C for weeks at a time. HVAC services in Rexdale cover furnace repair, air conditioner installation, heat pump replacement, and water heater service. Smile HVAC has served residential properties in Rexdale for over 15 years, with TSSA-certified technicians licensed in gas, plumbing, electrical, and refrigeration.

Faulty igniters, failed pilot assemblies, and heat exchanger cracks are the leading furnace failures in Rexdale. Each requires source-level diagnosis before parts or replacement are recommended
An oversized or poorly maintained AC starts and stops without completing a full cooling cycle. Common causes are dirty evaporator coils, refrigerant loss, and blocked filters
Blocked HVAC filters reduce efficiency in older Rexdale homes. Restricted airflow forces equipment to run longer and accelerates blower motor wear
Older thermostats lose accuracy over time, causing furnaces and ACs to cycle incorrectly and raising energy costs without improving comfort
Aging ductwork distributes conditioned air inconsistently, creating cold upper floors in winter and overheated rooms in summer
We begin with a thorough assessment of your Heating Systems or Air Conditioning Systems. Our technicians identify the root cause of the issue, explain the problem clearly, and provide transparent recommendations for HVAC repair in Rexdale .
Once approved, we perform precise repairs using quality parts and proven methods. Whether it’s a furnace, air conditioner, or full system upgrade, we ensure your equipment operates safely and efficiently.
After completing the work, we test the entire system to confirm peak per formance. We also provide maintenance tips to help prevent future breakdowns and keep your HVAC system running reliably in ever y season.

Modern high-efficiency furnaces reach AFUE ratings of 95 to 98%, converting nearly all consumed fuel into usable heat. Older furnaces rated 60 to 80% AFUE waste 20 to 40% of fuel per cycle, directly raising home energy bills. A recommended model is the Lennox Elite EL297 furnace, which achieves up to 97% AFUE.
Today’s central air conditioners range from 14 to 21 SEER. Smile HVAC recommends the Lennox ML 14 SEER for Rexdale homes, which meets Canadian standards. Higher-SEER models take over 11 years to pay back their added cost, a poor investment for most homeowners.
Gree heat pumps reduce energy consumption by providing both heating and cooling from one unit, with COP ratings above 3.0.
Practical efficiency steps for Rexdale homes:
Rexdale HVAC rebates are available through Ontario’s Home Renovation Savings (HRS) Program, active through November 2026. Cold-climate heat pumps reduce energy consumption and qualify because they meet government performance thresholds, maintaining heating output down to -25°C. To be eligible, homeowners must use a licensed contractor, install qualifying equipment, and register through the program portal. Smile HVAC offers free estimates and handles each step before scheduling work.
Rebate amounts by home type:
Rexdale is a northwest Toronto community with housing stock averaging 30 to 50 years old. At this age, HVAC equipment and ductwork rarely meet current efficiency standards. The neighbourhood includes single-family detached homes, townhouses, and apartment buildings — each with distinct ductwork and equipment requirements.
The Rexdale climate, from -15°C winters to 30°C summers, creates local HVAC challenges. Furnace Systems provide home heating through the long heating season; Air Conditioning Systems handle home cooling in summer. These local HVAC needs require energy-efficient solutions.
Key local factors shaping HVAC requirements in Rexdale:
Furnace installation in a Rexdale home takes 4 to 8 hours. Furnace Systems require professional installation for safe gas connections and venting. Air conditioner replacement takes 4 to 6 hours. Smile HVAC uses in-house TSSA-certified technicians with no subcontractors.
Gree heat pumps are an alternative to a traditional separate furnace and AC system, providing dual functionality from one unit. Cold-climate models operate down to -25°C and qualify for Ontario’s HRS rebates. Heat pump installations require professional sizing by a certified HVAC technician.
Smile HVAC installs, repairs, and maintains both tank and tankless water heaters across Rexdale. 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 Rexdale 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 Smile HVAC 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 Rexdale homes.
Smile HVAC diagnoses, repairs, and installs furnaces across all major brands, including Lennox, Goodman, Carrier, and York. The diagnostic fee is $120 + tax. When a repair is performed, that $120 + tax is deducted from the final price, making the service call effectively free.
Smile HVAC repairs and installs central air conditioners and heat pumps in Rexdale. For new installations, Smile HVAC focuses on the Lennox ML 14 SEER, which meets Canadian efficiency standards. Higher-SEER models cost more upfront and only start paying for themselves after about 11 years, making them a poor investment for most homeowners.
Smile HVAC uses in-house technicians only, holds TSSA certification, and backs installations with a 10-year workmanship warranty. Under the First Time Quote policy, the quoted price never increases after work begins. No hidden fees, no program change fee, and no cancellation fee apply.
Smile HVAC’s office is available 24 hours a day, seven days a week across Rexdale and the GTA. Call 437-777-4555 for urgent HVAC service.
Verify TSSA certification, a refrigeration licence, and proof of WSIB coverage. A reliable contractor provides a written quote and holds it firm. Smile HVAC carries $5,000,000 in liability insurance and is a Lennox Premier Dealer and Google Guaranteed contractor.
A new furnace typically costs $3,500 to $5,500 installed. Central air conditioner installation ranges from $3,000 to $6,500. Heat pump costs vary by system type and can be offset by Ontario’s HRS rebate program. Smile HVAC provides free estimates for all Rexdale installations.
Ontario’s HRS Program offers up to $7,500 for a cold-climate heat pump in electrically heated homes, up to $12,000 for ground source systems, and up to $2,000 for gas-heated homes. Smile HVAC confirms eligibility before work begins.
Furnace installation takes 4 to 8 hours. Air conditioner installation takes 4 to 6 hours, assuming no ductwork modifications are required. Smile HVAC schedules most Rexdale installations within the same week as the home assessment.
Heating systems benefit from annual servicing each fall. Cooling systems need a spring tune-up before demand peaks. Smile HVAC offers a Maintenance Plan from $9.99/month and a Protection Plan from $14.99/month, covering scheduled and emergency service.
Watch for a furnace cycling without reaching temperature, banging or rattling noises, rising energy bills, uneven room temperatures, or an AC running non-stop. Any of these signs warrants inspection by a certified technician within 24 hours.
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
