Local considerations

Combustion appliances in Boston require adequate fresh air for safe operation. Sealed homes with modern insulation can starve a furnace of combustion air, which shows up as cycling or incomplete combustion rather than a dramatic failure.

Combustion air requirements in Boston are affected by home improvements that seal the building envelope. A furnace with adequate combustion air when installed may not have enough after weatherisation work is done around it.

Furnace Repair in Boston

Cold-snap calls arrive in clusters, which is why a furnace repair at 11 pm in January is a genuinely different urgency than a tune-up in September.

Furnace Installation and Replacement service

Furnace Installation and Replacement in Boston

Rising fuel bills combined with longer run times are the quiet signal that a furnace is losing efficiency and the replacement clock is running.

Details

Heat Pump Repair in Boston

Defrost cycles that seem to run too often or not at all point at the defrost control board, which is a straightforward replacement once confirmed.

Details

Boiler Repair in Boston

A boiler losing pressure in midwinter risks frozen pipes as well as cold rooms, so it moves to the front of the queue.

Thermostat Installation and Repair service

Thermostat Installation and Repair in Boston

Heat pump thermostats have additional complexity in the form of balance points and auxiliary heat staging, which means replacement requires matching the control to the equipment.

HVAC Maintenance and Tune-Up in Boston

A tune-up before the heating season catches the igniter that is weakening, the limit switch that is drifting and the filter that is already loaded.

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 Boston

A heating failure in Boston is a timing problem as much as a repair problem. The sooner the call goes in, the more of the local provider capacity is still uncommitted.

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

Boston HVAC questions

What heating systems do you cover in Boston?

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 Boston?

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.
