24/7 Emergency Heating and Cooling Service in Windham, NH
The person who answers is the person who comes out
What this work is
If you have no heat, no hot water or no cooling right now, call (603) 571-7100. Emergency service runs 24 hours a day, every day of the year, and the person who answers the phone is the person who comes to the house.
You describe what the system is doing, you get a real answer about what it probably is and what happens next, and you deal with the same person from that call through to the finished repair. The phone rings on the technician's phone.
Every make and model, gas and oil, heating and cooling. No heat, no hot water, a boiler that keeps locking out, a furnace that will not fire, an oil burner that ran out and needs priming, a frozen or flooded condensate line, water on the floor around the boiler, or an AC system that quit in the middle of a July heat wave with a baby in the house.
Being licensed for both fuels matters most at two in the morning. A no heat call in southern New Hampshire is as likely to be oil as gas, and holding both the NH gas license and the NH oil heating technician license means the truck that shows up is the right truck either way.
One thing to be clear about, because it is safety and not sales. If you smell gas, or smell oil strongly, or if a carbon monoxide alarm is sounding, get everyone out of the house first, then call the gas utility or 911 from outside. Make that call before you call anybody about a repair.
What it costs
What this costs in southern New Hampshire
Nobody in this county publishes a number, which is exactly why these are here. The figures below are what the market charges, gathered from published cost data rather than from a quote sheet. Your house sets the final number, and you hear it before anything starts.
What an emergency call costs depends on the hour it comes in and on what is actually wrong, and neither of those is knowable from a chart. Here is what moves it, and you hear the number before anyone starts work.
What moves the number on your house
- When the call comes in
- A weekday afternoon and a two in the morning callout in a snowstorm are not the same visit, and you hear which one applies before anyone gets in the truck.
- Diagnosis against repair
- Finding the fault and getting the system running safely is one thing. Parts and the repair itself are quoted once the fault is known.
- Part availability
- Common parts get carried on the truck. An obsolete control board on a thirty year old unit sometimes means a temporary fix tonight and the real repair when the part lands.
- Whether the system is safe to run
- Occasionally the honest answer is that a unit should stay off until it is repaired. That changes the plan and you get told immediately, not afterwards.
You get the number before the work starts, including on an emergency call. Nobody should be finding out the price after a repair at midnight.

Before you call
What to check, what to call about, and what to do while you wait
Some of these turn a long cold night into a thirty second fix, and none of them cost anything. Work down the list, then call either way.
The thermostat
Confirm it is calling for heat and that its batteries are good. A dead thermostat looks exactly like a dead boiler from upstairs.
The emergency switch
Usually a red plate at the top of the basement stairs or beside the boiler. It gets bumped far more often than anyone expects.
The breaker
Check the panel. A tripped breaker on the boiler circuit is common after a storm or a brownout.
The oil tank gauge, if you are on oil
An empty tank is one of the most common no heat calls of the season. If you find a reset button, press it once and once only. Repeated resets pump raw fuel into the chamber and turn a small problem into a large one.
If you smell gas, or a carbon monoxide alarm is sounding
Get everyone out of the house first. Do not touch light switches or anything electrical. Call your gas utility or 911 from outside once you are clear. That call comes before any call about a repair, and the same goes for a strong smell of oil.
While you are waiting, in a hard freeze
Open the cabinet doors under sinks on exterior walls, let a faucet run a thin trickle at the far end of the plumbing, close the doors on rooms nobody is using, and keep everyone in one part of the house. That protects the pipes, which is the expensive part of a long cold night.
24/7 Emergency Service, answered
- What should I check before I call?
- Four quick things. Confirm the thermostat is calling for heat and its batteries are good. Check the emergency switch, usually a red plate at the top of the basement stairs or beside the boiler, because it gets bumped more often than you would think. Check the breaker. If you are on oil, check the tank gauge, because an empty tank is one of the most common no heat calls of the season. If you find a reset button, press it once and only once. Repeated resets pump raw fuel into the chamber and turn a small problem into a large one.
- What counts as an emergency?
- No heat in cold weather, no hot water, water leaking around the boiler or the air handler, a system that shut itself down and will not restart, or no cooling during a heat wave with young children or older family in the house. If you are unsure, call and describe it. You will get an honest answer about whether it can wait until morning, including when it can.
- Do you cover my town at night?
- Windham, Salem, Derry, Londonderry, Pelham, Hudson and Litchfield most often, plus Atkinson, Manchester, Auburn, Chester, Hampstead, Bedford and the rest of southern New Hampshire, at any hour. If your town is not on that list, call anyway and you will get a straight yes or no rather than being strung along.
- I smell gas. What do I do?
- Get everyone out of the house, do not touch light switches or anything electrical, and call your gas utility or 911 from outside once you are clear. That call comes first, before any call about a repair. The same goes for a sounding carbon monoxide alarm.
- My heat quit and I am waiting. What can I do in the meantime?
- In a hard freeze, open the cabinet doors under sinks on exterior walls, let a faucet run a thin trickle at the far end of the plumbing, close doors on rooms you are not using, and keep everyone in one part of the house. That protects the pipes, which is the expensive part of a long cold night.
