Heating calls in Dover
Heating faults in Dover reach this line through the same number as cooling, but they are a different kind of urgent. Long cold winters with a significant oil and boiler stock, where freeze protection is critical. A house losing heat has a shorter safe window than one losing cooling, and the triage reflects that.
All 3 ZIP codes shown sit within Dover, Strafford County. During a freeze event the ZIP code matters more than usual, because travel time decides who can realistically reach you.
Local considerations
Freeze protection matters in parts of Dover where pipework runs through unconditioned space. A boiler losing pressure in midwinter risks frozen pipes on top of the cold rooms, which is why those calls move up the queue.
A cracked heat exchanger ends the repair conversation in Dover as anywhere else. It is a carbon monoxide risk rather than a comfort issue, and the correct response is replacement rather than patching.

02 Furnace Installation and Replacement in Dover
Frequent lockouts on an older furnace mean escalating repair costs toward a number that makes replacement the more sensible use of the money.

03 Heat Pump Repair in Dover
Heating mode adds the reversing valve and the defrost cycle, and a unit stuck on auxiliary resistance heat still warms the house while the bill climbs.

What is your thermostat reading?
Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

- Likely cause band
- Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.

- Call today
- Read next
- AC not cooling
What to do while you wait
- Switch the thermostat off so the system stops attempting ignition over and over.
- Confirm the gas supply valve is open and that a service switch has not been knocked off.
- Check the filter. A blocked one makes the furnace overheat and shut itself down.
- Keep interior doors open so the warmth remaining in the house distributes evenly.

Dover HVAC questions
Why does my furnace smell when it first runs?
A brief dusty smell on the first run of the season is normal as dust burns off the heat exchanger. A persistent burning smell, or any electrical smell, is not. Shut it off and call.
What if I smell gas?
Leave the building first, then call the gas utility or 911 from outside. Do not operate light switches, thermostats or phones on your way out. Call us afterwards, once the utility has made the property safe.
Why are my upstairs radiators cold?
Usually trapped air or a circulation problem rather than a failed boiler. Bleeding radiators resolves some of it. If pressure keeps dropping after bleeding, there is a leak somewhere in the loop worth finding.
How do you decide which provider gets my call?
By ZIP code first, then by who is accepting calls. We publish no ratings and sell no placement. During a cold snap the set of available providers in Strafford County narrows considerably.
Do you send your own technicians to Dover?
No. HVAC Emergency USA is a referral service that connects homeowners with independent local providers. We do not own trucks, employ technicians or carry out work. Verifying licence and insurance before work starts is your responsibility.
