Learn more →Carleton Place: mill town and commuter town
Carleton Place grew up as a mill town on the Mississippi River, and its downtown still has solid stone and brick houses from the late 1800s and early 1900s. Around that core are post-war bungalows, 1970s–90s neighbourhoods, and the large new subdivisions that have spread along the edges of town as Ottawa commuters moved west along Highway 7.
Older stone and brick homes often have thick walls, little insulation, and either patched-together ductwork or hot-water radiators. Newer houses are the opposite: airtight, well insulated, and built with condensing gas furnaces, air conditioning and mechanical ventilation.
Outside town, Beckwith Township and the shores of Mississippi Lake are mostly rural, with private wells, propane and oil heat, and some former cottages now lived in year-round.

Furnace and boiler service in Carleton Place
For an older downtown home, the first question is whether the house has ducts at all. If it does, we size a new 96–98% AFUE furnace to the actual heat loss, which is often lower than the old, oversized unit suggests once windows and attic insulation have been upgraded.
If it’s heated by radiators, we service or replace the boiler and look at ductless cooling, rather than opening floors and walls for ductwork in a heritage house.
| Carleton Place project | Typical installed range |
|---|---|
| High-efficiency gas furnace (96–98% AFUE) | $4,500 – $8,500 (variable-speed/modulating up to ~$10,500) |
| Boiler replacement (high-efficiency combi or heating boiler) | $7,000 – $15,000 |
| Furnace + AC combo replacement | $8,000 – $15,000 |
| Ductless mini-split, multi-zone (2–4 heads) | $7,000 – $16,000 |
| Gas fireplace / insert installed | $3,500 – $7,500 |
| HRV / ERV installed | $2,500 – $5,500 |
All figures are typical Ottawa-region installed ranges before rebates. Your home, your equipment choice and the venting or ductwork involved decide the final price, and there’s no charge for an estimate on a new installation.

New subdivisions: upgrades and add-ons
In Carleton Place’s newer neighbourhoods, most calls are for upgrades rather than emergencies. Popular projects include adding a gas fireplace to a basement family room, running a BBQ line to the deck, and swapping a basic thermostat for a smart one.
New-home furnaces and air conditioners still need yearly maintenance. A builder-installed system that’s never been checked can run for years with a low refrigerant charge or a dirty flame sensor before it quits on the coldest night.
Frequently Asked Questions
Straight answers from licensed Ottawa technicians. Still have a question? Call us any time.
Does Oria service Carleton Place?
Yes. Carleton Place sits in our western service area, alongside Stittsville and Kanata. Technicians head out from our Nepean shop along Highway 7, and we also cover Beckwith Township, Mississippi Lake and the rural roads in between. Heating, cooling, water heater and gas line work is all available, plus round-the-clock emergency calls when something fails.
Can you add central air to an old stone house in Carleton Place?
Yes, though ductwork is often the hurdle. If the house has forced-air ducts, central AC is straightforward once we confirm the ducts can carry enough air. Homes on radiators or baseboards usually get a ductless mini-split instead. A multi-zone system with two to four heads typically costs $7,000 – $16,000 installed and also heats efficiently.
Is it worth adding a heat pump to a propane furnace at Mississippi Lake?
It can be. In a dual-fuel setup, a cold-climate heat pump handles most of the heating season and the cooling, while the propane furnace takes over on the coldest nights. That cuts propane use sharply without giving up a fuel-fired backup. We compare installed cost and expected savings for your home before recommending it.
What does a furnace and AC replacement cost in Carleton Place?
Replacing both together typically costs $8,000 – $15,000 installed, before rebates. A furnace alone usually runs $4,500 – $8,500 and a central AC $4,000 – $8,000. Doing both at once saves labour and ensures the indoor coil, blower and outdoor unit are properly matched. Estimates on new installations are free, and financing is available on approved credit.
Do you install gas fireplaces in Carleton Place?
Yes. We install natural gas and propane fireplaces and inserts, including direct-vent units for basements and family rooms. Installed costs typically run $3,500 – $7,500, depending on the unit, the venting route and any gas line extension. Direct-vent models draw combustion air from outdoors, so they suit tight new homes and don’t need a chimney.
Can a modern boiler work with the radiators in my older home?
Usually, yes. High-efficiency condensing boilers can heat existing cast-iron radiators and are far more efficient than old cast-iron boilers, especially when run at lower water temperatures on milder days. A combi boiler can also replace your water heater. Boiler replacements typically cost $7,000 – $15,000 installed, depending on venting and piping changes.
