If your system isn’t responding, is short-cycling, or struggling to maintain the right temperature, the thermostat may be the problem. GEM technicians can repair, replace, and recalibrate thermostats to ensure accurate communication between your system and your comfort settings.

A system that won’t turn on or isn’t producing warm or cool air is one of the most urgent HVAC problems we see. Whether the issue is electrical with your ductless systems, mechanical breakdown of your AC, or related to system controls, GEM can diagnose the cause and restore reliable operation as quickly as possible.

Uneven temperatures, weak airflow, or rooms that never feel comfortable often point to airflow issues. GEM repairs blower motors, addresses duct-related concerns, and resolves restrictions that prevent air from circulating properly from your cooling or heating throughout your home.

Banging, rattling, squealing, or unusual smells are signs that something isn’t right. These issues can stem from loose components, worn parts, or mechanical failures. GEM can identify the source of the problem to prevent further damage and keep your system running safely.

Poor cooling from your AC, ice buildup on your heat pump, or rising energy bills may indicate a refrigerant issue. Our technicians can locate leaks, make necessary repairs, and restore proper refrigerant levels to help your air conditioning system cool efficiently again.

Capacitors, contactors, motors, and control boards are critical to system operation but are also common points of failure over time. GEM can replace faulty components with quality parts and test the system thoroughly to ensure dependable performance.
