Frequently asked questions
October, before the first freezing night. Furnace slots fill quickly, so most pros recommend booking servicing no later than mid-October.
Air sealing plus attic insulation. Heating pros typically quote recoverable savings of 10-20 percent on winter heating bills, which usually outpaces every other measure.
For a typical home, a furnace service plus air sealing runs $300-600 one-time and reliably prevents the most common $500+ emergency calls - a good return for most households.
