Nepean covers a wide span of building eras, and which decade your house went up tells us most of what we need to know before we arrive.
Much of Nepean was built between the 1960s and the 1990s, with forced-air gas heating and ductwork already in place. A central cold-climate heat pump can use that ductwork directly. The one thing worth checking on homes of this vintage is whether the duct sizing suits the airflow a heat pump wants, since a heat pump moves more air at a lower temperature than a furnace does. That is a straightforward assessment, and it occasionally explains why a neighbour was unhappy with theirs.
The most common Nepean job we see is a house where the furnace and the AC are both around the same age and both due. That is the point where a heat pump makes the most sense, because you are replacing two machines with one. The incentive for a gas conversion is about $500 per ton, typically $1,250 to $1,600 on a Nepean home. Worth having, though it is the two-for-one that carries the decision.
Nepean spans enough decades that services range from 100 amp in the older sections to 200 amp in the newer ones, and homeowners often expect the older ones to be a problem. In 2026 they rarely are. A load manager lets a heat pump run on a 100 amp service alongside the rest of the house, and an upgrade is only likely for a large home with big extra loads such as a sauna or hot tub. We take care of the load calculation and the load manager; you just need your last year of electricity usage from Hydro Ottawa or Hydro One, which is in your online account.
We cover Nepean including Barrhaven, Bells Corners, Craig Henry, Centrepointe and Manordale, along with Stittsville and Kanata to the west.
Sizing decides everything else, including whether your electrical service can carry the system. Our heat pump design tool runs a load calculation for your address, and the panel sizing tool will tell you where your service stands.
