Heating Services

Reliable Heating Installation, Repair And Maintenance Services

Reliable heating is essential for homes and businesses across Ontario. During cold winter months, furnaces, boilers, and heating systems work hard to keep indoor spaces comfortable and safe.

Furnace Installation

Extel Gas installs furnaces for residential and commercial properties across Scarborough, Toronto, Markham, Pickering, Ajax, Whitby, Mississauga, and Brampton. If your current furnace is old, inefficient, noisy, or no longer heating properly, a new high-efficiency furnace may help improve comfort and reduce wasted energy.

Furnace Repair

If your furnace is not turning on, blowing cold air, making unusual noises, short cycling, or failing to heat your space evenly, Extel Gas provides furnace repair and heating repair services across the GTA.

Boiler Installation and Repair

Boiler systems are commonly used in many homes, older properties, commercial buildings, and hydronic heating systems. Extel Gas provides boiler installation, boiler replacement, boiler repair, and boiler maintenance services.

Cooling Services

Reliable Air Conditioning Installation, Repair And Maintenance Services

During hot and humid Ontario summers, a reliable air conditioning system is important for indoor comfort. Extel Gas provides AC installation, AC replacement, AC repair, and air conditioning maintenance services for residential and commercial customers.

AC Installation

If you are installing a new central air conditioning system or replacing an older AC unit, Extel Gas can help you choose the right system for your home or business. Proper AC sizing and installation are important because an oversized or undersized system can lead to poor cooling, short cycling, humidity issues, and higher energy use.

AC Repair

Extel Gas provides AC repair for cooling problems such as warm air, poor airflow, water leaks, frozen coils, thermostat issues, strange noises, bad smells, and systems that will not turn on. Air conditioning problems can become stressful during peak summer weather, especially for families, tenants, seniors, employees, and customers.

Gas Services

Professional Gas Line Installation And Safety Services

Gas systems must be handled with care, knowledge, and proper safety procedures. Extel Gas provides gas line installation, new gas connections, gas appliance hookups, gas piping, and red tag clearance support for homeowners, contractors, landlords, businesses, and property managers.

Gas Line Installation

Extel Gas installs gas lines for furnaces, boilers, tankless water heaters, hot water tanks, fireplaces, gas stoves, dryers, BBQs, and commercial gas appliances.

New Gas Connections

New gas connections may be required for appliance upgrades, renovations, additions, commercial equipment, or property improvements. Extel Gas can inspect your setup, explain what is required, and complete the connection work with safety in mind.

Red Tag Clearance

A red tag usually means that a gas appliance or gas system has a safety issue or does not meet required safety requirements. Extel Gas provides red tag clearance services for furnaces, boilers, water heaters, gas lines, venting, and other gas-related concerns.

Water Heating Services

Reliable Tankless Water Heater And Hot Water Tank Solutions

Hot water is essential for homes and businesses. Extel Gas provides installation and replacement services for tankless water heaters, hot water tanks, and combi boiler systems.

Tankless Water Heater Installation

Tankless water heaters provide hot water on demand without storing water in a traditional tank. They are a popular choice for customers who want a space-saving and energy-efficient hot water solution.

Hot Water Tank Installation

Traditional hot water tanks remain a reliable option for many homes and businesses. Extel Gas installs and replaces hot water tanks based on your property’s hot water usage, available space, and system requirements.

Combi Boiler Installation

A combi boiler can provide both space heating and domestic hot water from one compact system. This can be a good option for certain homes and properties where space efficiency and combined system performance are important.

Indoor HVAC Services

Indoor Comfort and Air Quality Services

Indoor comfort is not only about heating and cooling. Humidity, airflow, ventilation, maintenance, and equipment performance also matter.

Humidifier Installation

Dry indoor air can cause discomfort during winter, including dry skin, static electricity, irritated breathing, and damage to wood furniture or flooring. A whole-home humidifier can help balance indoor humidity and improve comfort.

Annual HVAC Maintenance

Annual HVAC maintenance helps identify problems early, improve efficiency, reduce breakdown risk, and extend the life of heating and cooling equipment. Extel Gas provides maintenance for furnaces, AC systems, boilers, water heaters, humidifiers, and related HVAC equipment.

Emergency HVAC Services

Heating, cooling, gas, and water heating problems can happen unexpectedly. Extel Gas provides emergency HVAC services for urgent issues across Scarborough, Toronto, Markham, Pickering, Ajax, Whitby, Mississauga, Brampton, and nearby GTA areas.
