Not sure whether it's a quick fix or a service call? Send your question and a technician will call you back. Below are answers to the questions Long Island homeowners ask us most, taken from the reasons people called us from 2023 to 2026.
Something wrong right now, like no heat, a gas smell or water coming through a ceiling? Don't wait for a reply: call (631) 414-7141.
Check the filter, make sure the thermostat is on Cool and set below room temperature, and look at the outdoor unit: is the fan spinning and the coil clear of leaves and dirt? If the outdoor unit is silent or the indoor coil is iced, turn it off and call.

Usually not on its own. A system doesn't use up refrigerant, so a low charge means there's a leak. Topping it off without finding the leak buys a few weeks at best. We check pressures, look for the leak first, and on older R-22 systems we'll tell you when the repair stops making sense.

Almost always the condensate drain. The line clogs with algae and dirt, the drain pan overflows, or the condensate pump fails, and water ends up on the floor or the ceiling below an attic unit. Turn the system off, clear standing water, and call. We clear the line, check the pump and add a safety switch if there isn't one.

Check the thermostat setting and batteries, the service switch near the furnace or boiler, the breaker, the filter, and the oil tank gauge if you heat with oil. Press an oil burner reset button once only. If any of that doesn't bring the heat back, or you smell gas, stop and call.

Not necessarily. Start with fresh batteries if it takes them, then check the furnace or air handler switch and the breaker, because many thermostats lose power when the equipment does. A blown low-voltage fuse on the control board is another common cause. If the screen stays blank, call and we'll trace it.

A hot-water boiler usually runs around 12 to 25 psi. Pressure that climbs toward 30 and makes the relief valve drip usually points to a waterlogged expansion tank or a fill valve that won't shut off. Pressure that keeps dropping usually means a leak or a relief valve that's letting water out. Both need a technician.

The usual causes are a clogged filter, dirty coils, a system that short cycles, leaky ducts in an attic or crawlspace, and old equipment running at low efficiency. A tune-up catches the first three. If the system is old, compare running costs before you replace it, because the fuel you choose matters as much as the equipment.

If it's a grinding, screeching or metal-on-metal sound, yes. That usually means a failing fan motor bearing, a fan blade hitting something, or a compressor problem, and running it can turn a small repair into a big one. A short whoosh when a heat pump switches modes is normal. Call us for anything louder.
