How the houses in Oakville shape the work
Grimsby Heating and Cooling serves Oakville from Grimsby, and cooling makes up a large share of that work in summer. Air conditioners that run without cooling, leak water or trip the breaker are diagnosed by measuring pressures, temperatures and current draw. For new cooling, the choice between central air and ductless follows what the house's ducts can carry.
Air conditioner repair and installation in Oakville
Grimsby Heating and Cooling serves Oakville from Grimsby, and cooling makes up much of that work through the summer. Refrigeration and air conditioning is a compulsory trade in Ontario, which means a refrigerant circuit may only be opened by a mechanic holding the right qualification.
Work is performed by 313A refrigeration and air conditioning mechanics.
Common cooling faults and their causes
- Running but not cooling: often a low refrigerant charge from a leak, a dirty outdoor coil, or a failed capacitor that leaves the compressor or fan motor stopped.
- Water around the indoor unit: usually a blocked condensate drain, or an evaporator coil that froze and is now melting after the system shut off.
- Breaker tripping: a shorted compressor winding, a failing contactor or a seized fan motor drawing too much current.
The technician measures pressures, line temperatures and electrical draw before writing a repair price. More on this at air conditioner repair.
Central or ductless
Central air works where the existing ducts are large enough to carry cooled air to every floor. Where a house has no ducts, or no room to add them, a ductless system with wall-mounted indoor heads is usually the better fit. Both options are explained on the air conditioning installation page.

Should I replace my Oakville air conditioner and furnace at the same time?
Not automatically. If the furnace is young and working well, replacing only the air conditioner is reasonable, provided the new indoor coil matches the furnace blower's airflow. If both are near the end of their lives, doing them together lets the technician size them as one system and fit the coil once. Ask for both prices through the quote page and compare. See air conditioning installation.
Where do carbon monoxide alarms have to go?
The Ontario Fire Code requires a working carbon monoxide alarm next to each sleeping area in a home with a fuel-burning appliance, a fireplace or an attached garage. A gas furnace, gas water heater or gas fireplace all count. The alarm warns you after carbon monoxide is already in the air. It does not find the cause, such as a cracked heat exchanger letting combustion gases into the air the blower circulates, or a blocked flue. Test each alarm, confirm one sits outside every bedroom area, and have the heat exchanger inspected through furnace and AC maintenance.
My street is not on natural gas. How do I find out if it is coming?
Enbridge Gas provides natural gas service for the Town of Grimsby. If your home is not connected, Enbridge Gas has a form you can fill out, and its team will confirm whether gas is available or planned for your area and explain the next steps. Until then, the choice is usually between keeping the current system and moving to an electric heat pump, which needs no gas line. Contact Enbridge Gas first so you know your options, then compare them on our heat pumps page.
