Common Reasons Your AC Needs Repair

Air conditioning systems fail for a wide range of reasons. Knowing what to watch for can help you catch a problem early, before a minor issue becomes a costly breakdown.

Signs and causes our High Point AC repair team sees most often:

Lack of proper maintenance: Without regular tune-up service, small problems go undetected. A system that never gets checked is a system that can eventually fail at the worst possible time.
Refrigerant leaks: A refrigerant leak causes your system to lose cooling capacity gradually. Under EPA regulations, refrigerant must be handled by a certified technician and can’t legally or safely be managed by unlicensed individuals.
Drainage problems: Condensate drainage issues often trace back to improper installation or excessive condensation buildup. Left unresolved, they can cause water damage and mold growth.
Thermostat malfunction: A miscalibrated or failing thermostat prevents your system from regulating temperature correctly, even when the unit itself is functioning. Sometimes the fix is simple. Sometimes the thermostat needs replacement.
Dirty air filter: A clogged filter restricts airflow and can cause the unit to freeze over or blow warm air. Filters should be changed every one to three months, and it’s one maintenance task most homeowners can handle themselves.
An aging or inefficient unit: Older systems may cool adequately but show their inefficiency on your monthly utility bill. If your energy costs are climbing without an obvious cause, your AC’s efficiency may be the culprit.
Unusual noises: Banging, squealing, or screeching sounds point to mechanical problems inside the unit. These noises don’t resolve on their own and typically worsen if ignored.

Our goal with every AC service call is to extend your system’s lifespan through accurate diagnosis and quality workmanship, not just to get it running again today.

How to Reduce AC Repair Frequency

Preventive maintenance is the most reliable way to avoid unexpected breakdowns. A few consistent habits make a measurable difference in how often your system needs professional attention.

Change air filters every one to three months to maintain airflow and indoor air quality
Keep vents and ductwork clear and unobstructed throughout the home
Schedule an annual AC tune-up to catch developing issues before they become failures
Clear debris, vegetation, and buildup from the outdoor condenser unit to maintain heat exchange efficiency

Earnhardt Heating & Cooling, Inc. offers professional AC maintenance and tune-up services designed to catch problems early and keep your system running through the hottest months.

Why Is My AC Running but Not Cooling?

This is one of the most common calls we receive. The unit is on, the fan is running, but the air coming through the vents isn’t cold. Three causes account for most of these situations:

Refrigerant leak: Low refrigerant is a frequent culprit. As levels drop, the system loses its ability to transfer heat and cooling output falls. Only a certified technician can diagnose a leak, recover the remaining refrigerant, and recharge the system properly.
Dirty evaporator or condenser coils: Buildup on the coils blocks the heat exchange process. Combined with a clogged filter, this is one of the most common reasons an otherwise functional unit stops cooling effectively.
Thermostat issue: A faulty or miscalibrated thermostat may signal the unit to run without actually calling for the full cooling cycle. The fix can be as simple as recalibration or as involved as a full replacement.

Our technicians diagnose cooling failures quickly and explain what they find in plain language before any repair work begins.
