Four months of real heat, every summer
Your air conditioner in Hempstead has one real job, and it starts in June. Summer afternoons here average 82°F, and the unit runs hard through September to keep up. That's four months of long cycles, not the occasional hot week.
A tune-up before that stretch checks the parts that strain most under long runtimes, the refrigerant charge, the coil, the electrical connections. Nassau County has also seen its share of high wind over the past ten years, 143 damaging wind events since 2015. A service visit is also a chance to check that the outdoor unit came through the last storm season with nothing bent or loose.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
- What does AC maintenance include?
- A technician checks the refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and the condensate drain, since a clogged drain is one of the more common reasons a system stops cooling. They also check that the thermostat calls for cooling correctly and look over the electrical connections, since loose ones are a common cause of a system that will not start.
- How often does an air conditioner need maintenance?
- Once a year, ideally in spring before the heat sets in. Here the cooling season runs June through September, four months where the system runs through afternoons that average 82°F. A spring check gives a technician the chance to catch a weak capacitor or a low refrigerant charge before the system has to carry that load.
- Is AC maintenance worth it?
- Yes, because most of what breaks an air conditioner in summer shows warning signs a technician can catch first. A weak capacitor, a dirty coil, or a clogged drain all point to trouble before they cause a full breakdown. With 143 damaging wind events recorded here over the past ten years, an annual check also gives a technician a chance to look over the outdoor unit for anything storms may have loosened or bent.
