Frequently Asked Questions

Why isn’t my air conditioner blowing cold air?

This could be caused by anything from low refrigerant and dirty filters to mechanical issues or electrical faults. A professional inspection is the best way to find and fix the problem quickly.

Why does my AC keep turning on and off?

Frequent cycling, or “short cycling,” often indicates an issue with airflow, thermostat calibration, or system sizing. It’s important to address this early to prevent damage and higher energy bills.

What should I do if my AC stops working suddenly?

Check your thermostat settings, air filter, and circuit breaker first. If the issue isn’t obvious, contact GEM for fast, reliable service—we offer same-day repairs to restore your comfort.

Why is my air conditioner making strange noises?

Unusual sounds like banging, buzzing, or rattling typically mean something inside your unit is loose or worn out. Have it checked right away to prevent further damage or system failure.

How long does an AC repair usually take?

Most repairs can be completed in just a few hours, depending on the issue. GEM’s fully stocked trucks and experienced technicians allow us to complete most fixes in a single visit.
