Most air conditioners that run but do not cool trace back to a dirty filter, an incorrect thermostat setting, a blocked outdoor unit, or a frozen evaporator coil. A handful of these issues can be checked safely without tools, but a hissing sound, visible ice, or a system that will not restart points to a refrigerant or mechanical problem that needs a licensed technician. Galaxy Plumbing's HVAC team diagnoses and repairs cooling failures across the GTA.

A ductless split system in Ontario typically costs between $3,000 and $6,500 for a single-zone installation, while multi-zone systems can range from $6,000 to $15,000 or more depending on equipment selection, home requirements, and installation complexity. The final price can vary based on factors such as electrical upgrades, heat pump efficiency ratings, indoor unit placement, and the number of zones needed to properly heat and cool your home.

A ductless split system heats and cools individual rooms or zones without ductwork. It is an efficient and flexible solution for GTA homes without central air, older homes, additions, and basements.

Heat pump installation in Ontario typically costs between $5,000 and $14,000 all in, depending on the unit type, home size, existing infrastructure, and whether backup heating is included. Federal rebates can offset $3,500 to $6,500 of that cost for qualifying cold-climate installations.

Both heat pumps and gas furnaces are viable heating options for GTA homes. Gas furnaces cost less upfront and perform reliably in extreme cold. Heat pumps offer year-round efficiency and lower operating costs when sized and installed correctly, particularly for homes with moderate heating loads. The right answer depends on your home, budget, and long-term energy goals.

If your furnace stops producing heat, work through a short checklist before calling for emergency service. Many no-heat situations resolve with a thermostat adjustment, a filter check, or a reset. When the cause is not immediately clear, Galaxy Plumbing provides emergency furnace repair across the GTA.

A furnace blowing cold air is most often caused by thermostat settings, a clogged filter, a tripped high-limit switch, pilot light or ignition failure, or a problem with the gas supply. Some causes are simple to fix yourself. Others need a licensed HVAC technician.
