Frequently Asked Questions

Common indicators of critical trouble include: warm or room-temperature air blowing from registers, visible ice on refrigerant lines or the outdoor unit, screeching or grinding sounds from motor bearings, persistent burning or electrical smells, and water leaking around your indoor air handler. If you notice any of these signs, shut the system down to prevent compressor damage and contact A1 A/C Service at (239) 517-8873.

Standard residential cooling units should be professionally tuned and inspected once a year, preferably in the spring before heavy summer demand. For systems that provide both heating and cooling (heat pumps), bi-annual inspections (spring and fall) are recommended to ensure trouble-free year-round operation.

Consider replacing if your equipment is more than 10 to 15 years old, requires frequent repairs that cost more than half the value of a replacement, or uses phased-out R-22 refrigerant. Modern systems offer significantly higher SEER2 efficiency ratings, lowering electric bills and delivering more consistent indoor comfort.

Water leakage is most commonly caused by a clogged condensate drain line. High humidity causes moisture to condense on the cold evaporator coils; if algae, mold, or sediment block the PVC drain pipe, the drain pan overflows. Our maintenance and repair service clears clogs, treats pans, and tests safety float switches.

Pleated filters rated MERV 8 to 11 offer an excellent balance of dust/allergen capture without placing excessive static pressure on your blower motor. Very dense filters (MERV 13+) can restrict airflow if your ductwork and blower are not engineered for them, so consult with our technicians during your service visit.

First, check your main circuit breaker box to ensure the breaker has not tripped. Next, confirm your thermostat is set to "COOL" and the setpoint is at least 3 degrees below room temperature. If the breaker is fine and the system still fails to start, call A1 A/C Service at (239) 517-8873 for emergency dispatch.

Yes. Heat pumps operate as reversible refrigeration systems that provide both heating in winter and cooling in summer. We diagnose and service reversing valves, defrost control boards, supplemental electric heat strips, and heating thermostats.
