Nine months of heat, and winters that test every part of it

Calais needs heat from September through May. That is nine months of the year your furnace or boiler is the thing standing between your family and 14 degree nights. It runs long hours, night after night, all winter long.

Most homes here still heat with fuel oil. Oil systems depend on a steady spark to light the burner and a clean flow of fuel to keep it burning. Cold snaps push both harder, and a system that was already worn finds its limit fast, usually as no heat at the worst possible time.

Maine loses power often. More than half of households here went at least a full day without it in 2024, and the last ten years brought 128 winter storms and 67 damaging wind events to the region. When the power drops, so does your heat, and what comes back on afterward is not always working the way it did before.

Why is my heat not working?
The most common reason is that a furnace or boiler has lost its power, ignition, or fuel supply. Check the thermostat first, then the breaker, since a tripped one will stop the whole system cold. If you heat with fuel oil, which most homes here do, check the tank level too. Winter nights average 14°F here, so a furnace that will not fire needs attention fast, not overnight.
Why is my system running but not cooling the house?
If the blower runs but the air is not cold, the problem is usually with the refrigerant side, not the fan. A dirty filter can choke airflow enough to make the whole system struggle, so check that first since it is the one thing you can fix yourself. If the filter is clean and the air still is not cold, a contractor needs to look at the coil and refrigerant charge.
What can I check before calling for HVAC repair?
Start with the thermostat. Make sure it is set to heat or cool as needed and has power, since dead batteries stop a lot of calls that have nothing to do with the furnace or the AC. Check the breaker panel for anything tripped. Look at the filter and replace it if it is gray or clogged, since a blocked filter can cause problems that look like something bigger. If you heat with fuel oil, confirm there is oil in the tank before assuming the furnace itself has failed.
