How Electrical Issues Cause the Most Misdiagnosed AC Failures
Refrigerant problems and mechanical failures tend to get most of the attention when people think about AC repairs, but electrical faults are behind a significant number of residential system breakdowns and are often the last thing that gets looked at.
Capacitors, which store and release the energy needed to start and run the compressor and fan motors, are among the most frequent failure points. When a capacitor weakens, the motor has to work harder to start, which generates excess heat and wear that shorten the motor's life over time. In some cases, a failing capacitor is the only thing standing between a working system and a compressor replacement.
Contactors, the electrical switches that control power to the compressor, develop pitting and carbon buildup with regular use and can eventually fail to make consistent contact. Both components are relatively affordable to replace when caught early. The problem is when they go undetected long enough to damage something more costly.

What a Frozen Evaporator Coil Is Telling You
Finding ice on your air conditioning unit, whether on the indoor coil or along the refrigerant lines outside, understandably catches homeowners off guard. The most common causes are restricted airflow from a clogged filter or blocked return vent, and low refrigerant charge. Either condition prevents the coil from absorbing heat as it's supposed to, and moisture on its surface freezes instead of draining away normally. A frozen coil also means your system is working overtime to cool a space it simply can't reach at that point.
If you keep running a frozen system, you risk liquid refrigerant backing up into the compressor, which can cause serious, lasting damage to the unit's most expensive part. The right move is to turn the system off and call Long's Corporation for service. Switching to fan-only mode while you wait can help the coil thaw without putting additional strain on the system.
Frequently Asked Questions
Why is my AC unit making a loud screeching noise?
A high-pitched screeching sound usually indicates a problem with the blower motor belt or the condenser fan motor bearings. In older systems, the belt can slip or fray over time. If you hear a metal-on-metal grinding sound, it often means the motor bearings have worn out entirely. It is best to shut the system down immediately to avoid the motor seizing, which could lead to a much more expensive repair.
Is it normal for water to pool around my indoor AC unit?
No, water pooling around the furnace or air handler is a sign of a clogged condensate drain line. As your AC dehumidifies the air, moisture collects on the coils and drips into a pan. If that drain line is blocked by algae or debris, the water backs up and overflows. In Fairfax, the high humidity makes this a common issue. We recommend regular drain line flushing to prevent water damage to your flooring or drywall.
