How Do You Choose the
Right Air Conditioner for Your Home?

Choosing the right air conditioner depends on several important factors. These include how well your home is insulated, the age of the property, the configuration of your ductwork, how you typically use your cooling system, and the level of comfort you want to maintain during the summer months. If you also want to replace your heating, a heat pump provides both heating and cooling from one system.

FAQs

What Type of Air Conditioner Is Best for an Ontario Home?

The best air conditioner for an Ontario home depends on its size, layout, existing ductwork and cooling needs. Central air conditioners are well suited to homes with existing ductwork, providing whole-home cooling. Ductless mini-split systems are ideal for condos, older homes, additions and spaces without ducts. A home assessment helps determine which system best suits your property’s layout and cooling requirements. A professional assessment helps determine which option best suits your home’s structure, comfort needs, and cooling usage. 
Yes, an air conditioner helps reduce indoor humidity as part of the cooling process. When warm air passes through the system, excess moisture is removed, helping your home feel cooler and more comfortable during hot weather. Keeping indoor humidity below 60% in summer helps reduce conditions that encourage mould growth. A correctly sized unit can remove humidity more effectively than an oversized system that short-cycles.
Most air conditioners in Ontario last around 12–15 years, while well-maintained central AC systems may last up to 20 years. Actual lifespan depends on the system type, installation quality, maintenance and how often the equipment operates. Regular maintenance and timely repairs can help maintain efficiency and may extend the system’s service life.
Air conditioners use a refrigerant cycle to transfer heat from indoor air to the outdoors. The indoor evaporator coil absorbs heat, while the outdoor condenser releases it. Air conditioners also remove moisture during the cooling process, helping maintain a more comfortable indoor environment. Cooling efficiency is rated using SEER2 (Seasonal Energy Efficiency Ratio). A higher SEER2 rating means the unit uses less electricity for the same amount of cooling.
The price of a new air conditioner depends on several factors, including the system type, cooling capacity, brand and installation requirements. Costs vary depending on whether your home needs a central ducted system or a ductless setup, as well as the home’s size and layout. LG Home Comfort offers purchase and monthly payment options. A free in-home consultation helps determine the right system and provide an accurate quote for your home.

10 Signs You Need to Book AC Repair Services. Don’t Wait Until It Breaks

Air conditioners may show warning signs before a failure, although some equipment problems can occur suddenly or with little warning. If your AC stops working during peak summer, service availability may be more limited during periods of high seasonal demand. After-hours or emergency service may also be subject to different rates depending on the provider. Addressing developing issues earlier can help reduce the risk of additional equipment damage, a more extensive repair, or an unexpected system failure. Here are 10

Why Does My AC Unit Turn On and Off? (Short Cycling Explained!) 

Short cycling occurs when your AC repeatedly turns on and off after just a few minutes. This operating pattern puts excessive wear on the compressor and wastes energy. Frequent compressor starts increase energy consumption and place additional strain on the compressor. Short cycling can prevent your home from reaching or maintaining the desired temperature efficiently. It leads to a significant spike in utility costs and heavily strains your system, particularly the compressor. The compressor is typically the most expensive component

How Much Does an Air Conditioner Cost in Ontario?

Professional central air conditioner installation in Ontario generally costs between $4,000 and $9,000, while a single-zone ductless mini-split typically costs between $2,300 and $4,500 with professional installation. Multi-zone systems cost more depending on the number of indoor units your home requires. Beyond basic equipment pricing, total project costs depend on the required cooling capacity, equipment efficiency, necessary ductwork repairs, electrical upgrades, permits, and removal of the old unit. Understanding these additional installation costs upfront can help prevent unexpected budget surprises.
