Furnace and air conditioning service in Caledonia
Furnaces, air conditioners and heat pumps in Caledonia, explained in plain words by technicians who look at the house first: how old it is, what the ductwork is like and how the furnace vents.
What kind of heating does a Caledonia house have?
HVAC Waterdown serves Caledonia for furnace repair and replacement, air conditioning and heat pumps, whether the house runs on natural gas or propane. Tell us which fuel you have when you get in touch so the technician brings the right parts. You approve a written price before any work starts.
Natural gas or propane: does it matter?
It does. Furnaces and water heaters are set up differently for each fuel, with different orifices and pressure settings, so a furnace cannot simply be switched from one to the other without a proper conversion. When you book, say whether the house is on a gas main or a propane tank, and mention who supplies the propane if you know. Work is performed by TSSA-certified gas technicians.
What services are available in Caledonia?
- Furnace repair for gas and propane units
- Furnace installation and replacement, with the venting checked and sized correctly
- Air conditioner repair and new central or ductless air
- Furnace and AC maintenance once or twice a year
Could a heat pump make sense here?
For some homes, especially those paying for propane, a cold-climate heat pump paired with the existing furnace is worth a look. The heat pump does most of the heating and cooling, and the furnace takes over on the coldest days. Work is performed by 313A refrigeration and air conditioning mechanics. Rebates change, so they are checked before you decide. Our heat pump guide walks through the trade-offs.

My Caledonia home heats with propane. Can you service the furnace?
Yes. Propane furnaces are serviced and repaired much like natural gas units, with checks on the burners, ignition, venting and gas pressure suited to propane. Let us know the fuel when you book, along with the furnace's age and what it is doing. If you are weighing a change, a heat pump paired with the propane furnace is one option to discuss. Any repair is quoted in writing first.
I live in a designated heritage house. Can I add a new vent or an outdoor unit?
Possibly, but check first. Waterdown has 121 designated heritage properties, most of them in the old village core, and changes to the outside of the house, such as a new side-wall vent for a high-efficiency furnace or an outdoor air conditioning unit, may need the City of Hamilton's approval. Sometimes a different layout, like running the vent to a side or rear wall, keeps the street face untouched. Contact the City's heritage staff before you commit, then look at the options on our air conditioning installation page.
What decides the cost of a furnace repair?
Mostly the part that failed and the time it takes to find the fault. Cleaning a flame sensor or replacing a worn igniter sits at the small end. An inducer motor, a control board or a blower motor costs more, and a cracked heat exchanger is the expensive one, often the point where a new furnace makes more sense. Age matters too, because parts for older furnaces can be harder to find. You see a written price and approve it before any part goes in.
