What counts as a heating or cooling emergency?

No heat in winter, no cool air during a heat wave, a furnace or boiler that won't fire, an air conditioner blowing warm air, a frozen indoor coil or frozen pipes, water leaking from the indoor unit, an outdoor unit that won't run, the smell of oil or gas, or any electrical concern (burning smell, breaker tripping repeatedly).

How fast can you respond?

Response timing depends on urgency, call volume, location, and technician availability. Maintenance-plan customers receive priority scheduling, subject to availability.

Do you handle emergency air conditioning repair in summer?

Yes. Air conditioning failures during a heat wave are treated as emergencies, the same way no-heat calls are in winter. We repair central AC, ductless mini-splits, and heat pumps from many leading manufacturers.

Do you handle both heating and cooling emergencies?

Yes — one number for both. Our technicians work on furnaces, boilers, heat pumps, central AC, and mini-splits from many leading manufacturers, so you don't have to figure out who to call.

What does emergency service cost?

Applicable fees and expected timing are explained before dispatch whenever possible.

OVERVIEW

Built around how your home uses propane.

Heat that quits during a January cold snap and an air conditioner that dies during a July heat wave can make a home unsafe or unlivable. Maintenance-plan members may call for 24/7 emergency service; non-plan customers can request service during normal business hours. For a gas smell, suspected carbon monoxide, fire, or another life-safety concern, leave the property and call 911 first.

Typical response times and service area

Fast local response across CT

We focus on Fairfield and New Haven counties, and our technicians know the roads, weather, and common local issues. Response timing depends on urgency, call volume, location, and technician availability, so we do not quote a fixed arrival window in advance:

Life-safety situations (suspected gas leak, carbon monoxide) are triaged first — call 911 before you call us
No-heat and no-cool calls are prioritised by risk to the household and the property
Severe storms extend timing across the whole service area; we’ll keep you updated

Prioritizing safety and transparency

We always prioritize life-safety calls. When heavy weather hits Connecticut, we triage based on risk and provide arrival estimates so you can make informed decisions.

No-heat checklist — what to try while you wait

Quick steps to reduce risk and possibly restore heat

If your heat goes out in freezing CT weather, try these checks before a technician arrives. They can save time and reduce stress.

Check the thermostatIs it set to “heat” and above current room temp? Replace batteries if digital display is blank.
Confirm powerLook at your breaker panel and furnace/boiler switch. Reset a tripped breaker.
Inspect the fuel levelFor heating oil or propane customers, confirm there’s fuel in the tank.
Reset the systemTurn the thermostat off, wait 60 seconds, then back on. Some systems need a manual reset on the appliance.
Look for an error codeModern furnaces/boilers/ACs show codes — write it down and tell us.
Check vents and filtersClosed vents or a clogged filter can cause shutdowns.
Stay safeIf you smell gas or suspect carbon monoxide, evacuate and call 911 first.

If nothing fixes it, call (203) 533-8249 for immediate dispatch. If you’re a maintenance plan member, see the next section for priority benefits.

Check the thermostatset to “cool” and below the current room temperature; replace batteries if the display is blank.
Confirm powercheck the breaker panel and the outdoor disconnect switch; reset a tripped breaker once.
Replace a clogged filtera dirty filter can freeze the indoor coil and stop cooling.
Clear the outdoor unitremove leaves, grass clippings, or anything blocking airflow.
Look for iceice on the coil or refrigerant lines means turn the system off and let it thaw before restarting.
