AC Repair in Huntington Station, NY

Hot, sticky summers pull a lot of water out of the air. Two of our Huntington Station visits were drain line cleanings, one using nitrogen pressure to clear a stubborn blockage. A clogged line backs water into the pan, trips a float switch that shuts the system off, or overflows onto a ceiling or floor.

Nitrogen is a dry, inert gas, so pushing it through the line clears sludge without adding water or chemicals to the air handler. After clearing, we flush the line, confirm it slopes toward its outlet and make sure the safety switch resets properly.

On some outdoor units, dirt packs into the inside face of the coil where a hose from outside cannot reach. On one Huntington Station visit we removed the unit's outer jacket to clean the coil from both sides. With units wedged against fences and driveways on small lots, debris collects fast and airflow suffers.

A clean coil lets the system shed heat properly, which lowers pressures and running current. If your condenser sits beside a driveway or a neighbor's fence, check it each spring for leaves and seeds from street trees, and keep a couple of feet open around it.

Yes. The indoor blower has to move the right amount of air across the coil. Too little air and the coil can freeze; too much and the house feels cool but clammy because moisture does not condense out. One of our Huntington Station visits was a fan speed correction to fix exactly this kind of balance.

Fan speed often ends up wrong after a motor or board replacement, or when a system was left on factory defaults. We measure the temperature drop across the coil and the static pressure in the ducts to find the right setting instead of guessing.

Many Huntington Station homes near the station and off Depot Road heat with boilers and radiators and had no original ductwork. Cooling there is often a later attic system or window units. Attic air handlers in these houses can have long duct runs, tight access and drain lines that travel a long way to an outlet.

We look after the heating side in the same homes. Our records here include a boiler air bleeder replacement and heating tune-ups, so one company can cover both seasons. See our Huntington Station oil boiler tune-up project for an example.

When pressures and temperatures show the system is undercharged. One Huntington Station visit involved adding refrigerant beyond the standard amount. A low charge means a leak somewhere, so we look for oily spots on fittings, check the service valves and recommend a leak repair when the leak can be located.

Signs of low refrigerant include ice on the larger copper line, long run times and warm air at the registers. Turn the system off if you see ice, and call us. Our Long Island AC repair page, air conditioning repair page and AC not cooling page have more help.
