Heating calls in Lewiston

Carbon monoxide risk is the line that separates heating calls from cooling calls in Lewiston. Any combustion appliance deserves a working alarm nearby, and a sounding alarm means leaving the building before making any call.

Coverage runs to 3 ZIP codes across Lewiston. A ZIP code missing from this grid does not mean no provider covers it, only that we have not published a page for it yet.

Local considerations

Heat pump performance in Lewiston depends on outdoor temperature in a way that gas equipment does not. The capacity drop at low ambient temperatures is normal and predictable, and sizing accounts for it with auxiliary heat.

Duct losses on the heating side in Lewiston are easy to overlook because they do not cause a fault code. A forced-air system losing output to duct leakage in unconditioned space shows up as a comfort complaint, not a breakdown.

Services

Heating services in Lewiston

Below are the heating jobs Lewiston providers see most, across furnaces, boilers, heat pumps and the controls that run them.

6 services

Furnace Repair in Lewiston

A furnace that ran fine last winter can lock out at the start of this one simply because the flame sensor accumulated enough summer dust to fail the safety check.

Furnace Installation and Replacement service

Furnace Installation and Replacement in Lewiston

Frequent lockouts on an older furnace mean escalating repair costs toward a number that makes replacement the more sensible use of the money.

Details

Heat Pump Repair in Lewiston

A heat pump that runs constantly without warming the house is usually leaning on auxiliary resistance because the compressor side is not contributing.

Details

Boiler Repair in Lewiston

Circulator pump failure stops the heated water from reaching the radiators. The boiler may fire and reach temperature while every room stays cold.

Thermostat Installation and Repair service

Thermostat Installation and Repair in Lewiston

A control that will not switch into heating mode leaves the house cold while the equipment itself is perfectly serviceable.

HVAC Maintenance and Tune-Up in Lewiston

Flame sensor cleaning in October prevents the lockout that owners discover in January when the furnace refuses to light on a cold morning.

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.

Degrees F

Indoor temperature

Likely cause band: Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.
Urgency: Call today
Read next: AC not cooling

Thermostat reading against likely cause. JavaScript is off, so the dial is shown as a table.
Reading	Likely cause	Urgency
60 F	The heating side is not producing heat at all. Ignition lockout, a dirty flame sensor or a tripped limit switch.	Call now
62 F	The burner is lighting then dropping out, or the blower is running without heat behind it.	Call now
64 F	A heat pump that is not completing the switch into heating mode, or one stuck relying on auxiliary resistance heat.	Call now
66 F	Heat is being produced but not distributed. Airflow restriction, duct losses or a zoning fault.	Call today
68 F	Close to a normal winter setpoint. If the room feels colder than this reading, suspect the thermostat itself.	Call today
70 F	Within the normal comfort band. Nothing here points at a fault on its own.	Monitor
72 F	Within the normal comfort band. Worth noting how long the system runs to hold this figure.	Monitor
74 F	Slightly above a typical cooling setpoint. If the system cycles on and off rapidly, that is the fault to chase.	Monitor
76 F	The system is falling behind setpoint. Airflow restriction or a coil that cannot absorb heat.	Call today
78 F	Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.	Call today
80 F	Supply air is close to room temperature. The refrigerant side or the compressor is not contributing.	Call today
82 F	Well above setpoint with the system running. Check for ice on the indoor coil or the line set.	Call now
84 F	Substantial capacity loss. A leak that has been developing across the season is the usual finding.	Call now
86 F	The system is effectively not cooling. Check whether the outdoor unit is running at all or tripping its breaker.	Call now
88 F	Indoor temperature is approaching outdoor temperature, which means no useful cooling is happening.	Call now
90 F	A health risk in a heat event. Move anyone vulnerable to a cooler space and treat this as urgent.	Call now

What to do while you wait

Set the thermostat to off rather than leaving it calling for heat against a locked-out system.
If you smell gas, leave the building first and call the gas utility or 911 from outside.
Replace a loaded filter. Restricted airflow trips high-limit switches on furnaces.
Close off unused rooms and keep anyone vulnerable in the warmest part of the house.

Problems we route in Lewiston

Cold snaps in Androscoggin County generate more calls than the local provider network can absorb at once. The operator tells you honestly what the window looks like rather than booking one nobody can meet.

Emergency

If this is happening right now

Call now

No cool air during a heat advisory
No heat with outdoor temperatures below freezing
Burning smell from the vents
Water pooling at the air handler
Ice on the line set
Breaker tripping on every cycle

Call (855) 321-3194 and give your ZIP code.

Shut it off and call the utility or 911 first

You smell gas: leave the building, then call the gas utility or 911
Smoke or sparking at the equipment
A carbon monoxide alarm is sounding: leave and call 911

Reference: CPSC recalls and US Fire Administration heating fire safety.

Shut it down safely

Set the thermostat to off so the system stops cycling.
Kill the breaker at the air handler and at the outdoor condenser.
If you smell gas, leave the building first, then close the gas shut-off at the furnace only once you are outside and have called the utility or 911.
Clear the area around the equipment and keep pets and people away from it.

Questions

Lewiston HVAC questions

What heating systems do you cover in Lewiston?

Gas and electric furnaces, boilers, heat pumps running in heating mode, and the controls that operate them. Mention which you have when you call, because combustion work and refrigerant-cycle work need different parts on the truck.

Why is my heat pump running constantly?

A heat pump that never cycles off is usually low on charge, iced on the outdoor coil, or leaning on auxiliary resistance heat because the reversing valve is not completing the switch into heating mode.

Do I have to be home?

Yes. The technician needs access to the thermostat and the equipment itself, and someone has to approve the quoted price before work begins. For combustion appliances they may also want to check alarms.

What does heating repair cost in Lewiston?

We do not quote prices. The provider who attends confirms the price on site before work begins. Boiler and heat pump work generally takes longer to diagnose than a straightforward furnace fault.

What should I do before the provider arrives?

Set the thermostat to off rather than leaving it calling for heat against a locked-out system, replace a loaded filter, and close off unused rooms. Keep anyone vulnerable in the warmest part of the house.
