We just purchased a 2000 sq ft apartment (2nd and 3rd floor of a two family house). The house is probably 100 years old like most homes in the New England area. The home inspector thought the apartment was reasonably well insulated. The sellers mentioned that their gas bill is approximately $200/month but we have not seen copies of the bill.
Currently the apartment has a mix of cast iron radiators and baseboard heating. (Some rooms have both.)
We are considering replacing this system with a forced air system using hot water.
1. One estimate we have received said it would cost $32,000 (parts and labor) not including additional electrical work.
Is this reasonable?
2. Assuming the apartment insulation stays the same, would our gas bill reduce enough with the forced air hydronic system to justify the upfront cost?
3. Any recommendations for HVAC professionals in the Somerville, MA area?
