What countsGas or COWhile you waitWhat we fixFAQ
Heating and cooling failures don’t wait for business hours. We take emergency calls around the clock across Hicksville and nearby Nassau County towns.
What Counts as an HVAC Emergency
- No heat when it’s freezing outside
- No air conditioning in extreme heat – especially with elderly family members, infants or anyone with a health condition in the house
- Water leaking from a boiler, furnace or air handler, or a boiler relief valve discharging
- A burning or electrical smell, or a breaker that keeps tripping when the system starts
- A boiler or furnace that keeps locking out and won’t restart
If You Smell Gas or a CO Alarm Sounds
Get out first, then call
Leave the house immediately and don’t switch anything on or off. From outside, call 911 or National Grid’s gas emergency line. For a carbon monoxide alarm, get everyone out and call 911. Call us once responders have cleared the house.
While You Wait for Us
- Check that the thermostat is set correctly and has fresh batteries
- Check the breaker and the equipment’s service switch
- Replace a clogged air filter
- If the AC coil or lines are iced over, turn cooling off and run the fan only
- Use space heaters safely – keep them clear of anything that can burn and never leave them running unattended
- In a deep freeze, open sink cabinet doors on outside walls and let faucets drip to help keep pipes from freezing

Emergency Service FAQ
Do you really answer at night and on weekends?
Yes. Call (516) 930-5483 any time, 24/7, and we’ll give you a realistic arrival window.
Is emergency service more expensive?
After-hours visits can cost more than a scheduled appointment. We always tell you the price before any work starts.
What should I do if my pipes might freeze while I wait?
Keep interior doors open so heat reaches outside walls, open cabinet doors under sinks on exterior walls, and let faucets drip slightly. Never use an open flame to thaw pipes.
