Though today’s heating and cooling systems are more efficient and reliable than ever before, HVAC repairs can still be an unexpected event. Maintenance issues, damaged system components, and simple wear and tear require professional service to restore comfort and safety to your indoor environment.

One thing’s for certain: There’s never a convenient time to have an interruption in your home’s heating or cooling functions. Here are just a few issues that may require HVAC repairs:

Furnace

• Insufficient air circulation. A clogged filter can strangle furnace airflow, stressing the system blower, overheating critical components, and triggering a system shutdown. Leaks in ductwork are another cause of lost heating or cooling, necessitating HVAC repairs.
• Defective igniter. The electronic igniter lights the furnace gas burner when the thermostat signals for heat. The average life span of an electronic igniter is about seven years. Replacement is typically an uncomplicated procedure for a qualified furnace technician.
• Cracked heat exchanger. The heat exchanger is a vital safety component that keeps deadly carbon monoxide and other fumes safely out of household air. Because a heat exchanger may develop cracks over time, it’s a critical part of annual heating system maintenance by a certified HVAC professional.

Air Conditioner

• Refrigerant leaks. AC refrigerant leaks cause cooling performance to steadily decline, eventually blowing only warm air. An HVAC technician utilizes detectors to track down leakage in AC coils or lines, then performs necessary repairs and restores refrigerant charge to proper specifications.
• Coil icing. Ice formation on the indoor AC evaporator coil may cause the system to run almost continuously, triggering an automatic system shutdown. The most common cause of coil ice is low refrigerant due to leaks in the system.
• Drainage issues. A central AC generates countless gallons of liquid condensate daily. It’s collected in the drip pan beneath the indoor coil, from which it flows into a drain line. Condensate overflows due to clogs — often of algae or mold — may cause water damage. Professional service includes disinfecting the drip pan and blowing out the drain line to restore proper drainage.
