Get a QuoteOttawa winters often bring stretches of -20°C or colder, and summer heat waves can push temperatures past 30°C. That range puts real demands on your heating and cooling equipment. Your furnace or heat pump runs for much of the year, and your air conditioner has to manage humidity as well as heat. Indoor humidity above 60% creates conditions that can support mould growth, and a correctly sized air conditioner removes moisture as it cools. An oversized unit may short-cycle and remove less humidity, so correct sizing matters as much as the brand on the box.

Efficiency ratings help homeowners compare heating and cooling equipment. Furnaces are rated by Annual Fuel Utilization Efficiency (AFUE). For most new residential natural gas furnaces, Canada's minimum efficiency requirement is 95% AFUE, with specific exceptions. Air conditioners and heat pumps use SEER2 ratings for cooling efficiency, while HSPF2 measures heat pump heating efficiency. Higher ratings generally indicate more efficient equipment under standard test conditions. Natural Resources Canada's EnerGuide program provides equipment efficiency information. Whether you're considering a high-efficiency furnace, a new air conditioner or a heat pump in Ottawa, operating costs vary depending on your home and energy rates. An LG Home Comfort technician can provide a home-specific estimate. Enbridge Gas rebates may be available for eligible equipment. Confirm current programs and amounts directly with Enbridge Gas or through your LG Home Comfort technician.
Contact UsOttawa summers can be hot and humid, and an air conditioner that can't keep up makes the whole house uncomfortable. We install new central air conditioners and repair and maintain existing systems. Annual maintenance can support efficient operation and help identify developing problems. A typical service includes condenser coil cleaning, checking refrigerant performance and inspecting electrical connections and the condensate drain. Refrigerant handling requires appropriately certified technicians.

In Ottawa, winters can be a serious test for your furnace. We handle everything from routine maintenance and emergency repairs to high-efficiency furnace replacements. In Ontario, gas furnace work must be performed by appropriately certified technicians working for a TSSA-registered contractor. Homeowners can verify a contractor's registration with the Technical Standards and Safety Authority (TSSA). If you notice soot around the furnace, unusual smells or a carbon monoxide alarm, treat the situation as urgent and arrange appropriate assistance. A cracked heat exchanger can allow carbon monoxide to enter circulated air. Ontario has no mandatory furnace replacement age, so replacement decisions should consider repair costs, safety, equipment condition and efficiency.
Explore Ottawa Furnace Services A heat pump moves heat rather than burning fuel, allowing one system to provide heating in winter and cooling in summer. Cold-climate heat pumps are designed for lower outdoor temperatures, with some models rated to operate at temperatures as low as -25°C to -30°C. Actual heating capacity and efficiency depend on the equipment and outdoor conditions. Some Ottawa homeowners combine a heat pump with an existing gas furnace for backup heating during colder periods. In a dual-fuel configuration, the system can switch between the heat pump and furnace according to operating conditions. If installation requires a new electrical circuit, the work must meet applicable Electrical Safety Authority (ESA) notification and inspection requirements.
Explore Ottawa Heat Pump Services An unexpected loss of hot water during winter can be disruptive. We install, repair and maintain tank and tankless water heaters. Tankless models heat water on demand and avoid the stored-water standby losses associated with traditional tanks, but they may require higher gas flow, additional electrical capacity or venting changes. Rental water heaters are common in Ontario, so check your rental agreement before booking a replacement. Gas connections must be completed by appropriately certified technicians working for a TSSA-registered contractor. If your water is hard, mineral scale can build up on heating elements and tank walls and reduce efficiency. A water softener helps reduce the calcium and magnesium responsible for scale. For more information, read our water heater buying guide.
Explore Ottawa Water Heater Services Ottawa homes spend much of the year with the windows shut, so filtration and humidity control matter. We install and maintain air purifiers and humidity control equipment. In summer, indoor humidity above 60% creates conditions that can support mould growth. No single product solves every indoor air quality problem, so we'll look at your home's specific concerns before recommending suitable equipment.
