How the houses in Milton shape the work
Grimsby Heating and Cooling installs heat pumps, central air and ductless systems in Milton, and repairs and maintains the furnaces already there. Every installation starts with a heat-loss calculation and a look at the ducts and electrical panel, so the equipment suits the house. You get a written price to approve before work begins. Ask for a quote or describe a fault, and we arrange the visit.
Heat pumps are explained before they are quoted
A cold-climate heat pump is built to keep producing useful heat at low outdoor temperatures. A hybrid system pairs a heat pump with a gas furnace that takes over below an outdoor temperature you set. Which one fits depends on the heat loss of the house, the capacity of the ducts and the room left in the electrical panel, and the technician measures all three. Rebate programs change, so they are checked at the time of the quote. See heat pumps and the guide to heat pumps and rebates.
Central air where the ducts allow, ductless where they do not
Central air conditioning uses the furnace blower and existing ducts, so the ducts have to carry the airflow a cooling coil needs. Where they cannot, or where there is no ductwork at all, a ductless system with wall-mounted heads is usually the better fit. More on air conditioning installation.
Carbon monoxide alarms are part of the plan
The Ontario Fire Code requires a working carbon monoxide alarm next to each sleeping area of a home with a fuel-burning appliance, a fireplace or an attached garage. If you are keeping a gas furnace in a hybrid setup, ask the technician to look at where your alarms sit.

Can a heat pump fully replace the gas furnace in a Milton home?
It can, if the heat pump is sized to the heat loss of the house and the ducts can carry the airflow it needs. Some owners prefer a hybrid system, where the heat pump handles most of the season and the gas furnace runs on the coldest days. The technician measures heat loss, duct capacity and panel space before giving a written price for each option. See heat pumps.
Why is my furnace not kicking on, or blowing cold air?
When the thermostat calls for heat, the furnace runs a fixed sequence: inducer motor starts, pressure switch closes, igniter heats, gas valve opens, flame sensor proves the flame. A fault at any step stops the burner, and the blower may keep running and push cold air. Common causes are a dirty flame sensor, a cracked igniter, a blocked condensate trap or a clogged filter tripping the high limit. Switching the furnace off and on clears a lockout once, but repeated resets hide the fault. See our guide on a furnace running but not heating.
Should an old furnace be repaired or replaced?
Age alone does not decide it; the fault and the house do. A failed igniter or blower capacitor in an older furnace is a small repair. A cracked heat exchanger, the most expensive part on a furnace, usually means replacement, and it should not be left running because it can let combustion gases into the house. Parts availability, efficiency and whether the ductwork suits a new unit also matter. A replacement is sized from a load and duct assessment, not the old label. Read the repair or replace guide.
