Heating and cooling services in Waterdown
What does your furnace or air conditioner need?
HVAC Waterdown repairs and installs furnaces, central air, ductless systems and heat pumps, and looks after them between seasons. We start with your house: a converted chimney in the Griffin Survey, original ductwork in Glenlea or Renwood Park, or a side-wall vent and an HRV in Waterdown South. Knowing the era of the house usually tells us where to look first.

Air conditioner repair

Air conditioning installation
A new air conditioner should suit your house, not a catalogue page. In Waterdown that might mean central air on ductwork from the 1970s, a ductless system in an older house with radiators, or a replacement in a newer home where the AC shares a drain with the furnace. If your current unit needs fixing rather than replacing, see air conditioner repair.

Furnace and AC maintenance
A furnace in Waterdown runs hard from late fall into spring, then the air conditioner takes over. A tune-up before each season catches the small problems: a slow condensate drain, a dusty HRV filter, a tired chimney. It also keeps the records your manufacturer's warranty asks for. If something has already stopped working, see furnace repair.

No heat, cold air from the vents, a strange noise, or the furnace keeps starting and stopping
Read about Furnace repair. First check that the plastic vents on the outside wall are clear of snow and the filter is not clogged, then tell us what you are seeing.
The furnace is old, needs a major repair, or some rooms never warm up
Read about Furnace installation and replacement. A new furnace is sized to your house and ductwork, the venting and any water heater left in the chimney are looked at, and you get a written price first.
The central air runs but the house stays warm, water pools by the indoor unit, or the breaker trips
Read about Air conditioner repair. Turn the system off if it is leaking or tripping, and we will find the fault and repair it within the season.
You have no central air yet, or an older house with radiators or small ducts
Read about Air conditioning installation. Ducted homes usually suit central air, while older houses with radiators often do better with a ductless system.
You want to burn less gas without giving up a warm house in February
Read about Heat pumps. A cold-climate heat pump can work alongside your gas furnace as backup, and we check the current rebates before you decide.
Everything works and you would like it to stay that way
Read about Furnace and AC maintenance. A seasonal tune-up covers what your house type needs, from the condensate drain and HRV filter to the chimney, with records kept for the manufacturer's warranty.
