HVAC in Vermont is a long heating season built on oil, wood, or both. Boilers and radiators still heat village houses. Stoves carry farmhouses through a power cut if the flue is safe and the house can live without pumps. A heat pump with no backup will meet a night it cannot handle. That backup is the point of the call, not an extra. Say what actually keeps you warm when the lights go out.
A cold ell, a short-cycling boiler, and a chimney wrong for the present stove or burner are separate problems. A fuel smell at a tank is not a filter visit. Creosote and a lazy flue are reasons to stop improvising. Radiator valves leak onto floors and look like roof leaks. Spillage at a draft hood and a CO alarm end the experiment. You do not need the model plate to start. You need the fuel and the symptom.
Ductless heads get added to rooms the boiler never reached, especially finished attics and ells. They do not fix ice dams by themselves, and their condensate lines freeze when they dump outside. Wood heat loads the house with moisture that then ices the windows and the attic. Cooling is a short, humid stretch, not the center of the year, but a closed-up village house can still feel heavy in July. Say whether you are calling about no heat, a smell, or a room that was never on the system.
Power loss is ordinary in storms. Know which circulators, fans, and ignitions quit. A stove that cannot be left alone is not backup for a weekend away. Tanks in cold basements weep at fittings. Chimneys built for an older fire may be the wrong size now. Mention every appliance tied to the flue, including a water heater, so the draft story is complete.
Have the town, the fuels, and the room that fails. Say if the driveway will limit a delivery or a service visit after a storm. Mention backup heat plainly. Call the number on this page.
