5 Signs It’s Time to Call an AC Technician


Air conditioning systems require regular maintenance and periodic repairs to operate at peak efficiency. But how can you tell when an issue in your AC system is starting to develop? Watch for these 5 warning signs that it’s time to call in a professional AC technician.

1. Increased Utility Bills

One of the most obvious indicators of AC problems is escalating electricity costs during warm weather. Several different issues can cause an AC system to consume extra energy trying to cool your home:

– Low refrigerant levels – Refrigerant is needed to move heat out of indoor air. Low levels reduce cooling capacity, forcing your AC to run longer.
– Dirty coils/filters – Clogged evaporator coils and air filters restrict proper airflow, decreasing cooling effectiveness and efficiency.
– Faulty controls – Thermostats, sensors and other controls going haywire makes systems overcool, undercool or cycle too much.
– Sealing and insulation issues – Leaky ducts and inadequate insulation waste cooled air, requiring extra AC runtime.

Your technician can pinpoint what’s causing the spike in energy use and remedy it quickly to restore efficient operation.

2. Strange Sounds

Your AC system should run quietly, with only minimal hums and vibrations. Odd new sounds are clear indicators of problems needing attention. For example:

– Screeching, grinding or squealing noises signal motor or belt issues.
– Clanking and banging may indicate loose parts inside the condenser or blower units.
– Buzzing or humming points to electrical shorts.

Don’t ignore strange new sounds coming from your AC system. An expert technician can listen and isolate the origin of the noise for repairs.

3. Poor Airflow

Notice if the airflow from your vents seems weaker than normal. Restricted airflow is a sign of deeper issues impeding AC performance. Causes can include:

– Clogged filters
– Stuck dampers or closed vents
– Kinked flexible ductwork
– Obstructed coils or blower assembly
– Undersized ductwork
– Excess humidity

Reduced airflow delivery leads to uncomfortable hot and cold spots. A technician has the tools and skills to measure airflow, identify restrictions and restore proper air distribution.

4. Intermittent Operation

It’s definitely concerning if your AC system starts randomly shutting off before reaching the set temperature. This points to:

– Refrigerant leaks – Low levels cause the compressor to overheat and shut off as a safety precaution.
– Electrical issues – Fuses, breakers, wiring and connections must be in good order to avoid shutdowns.
– Control or sensor malfunctions – Faulty components provide improper input to your AC, leading to premature shutoffs.

Intermittent operation prevents your system from adequately cooling your home on hot days. Don’t delay diagnosis and repair of underlying causes.

5. Water Leaks

Water collecting under or around your indoor air handler or outdoor compressor unit signals trouble. Potential causes include:

– Clogged condensate drains or pans – AC systems produce condensation that must drain properly. Clogs cause water to spill from the unit.
– Refrigerant leaks – Leaking refrigerant lines develop ice that melts into water puddles.
– Coil leaks – Small cracks or holes in the evaporator coils also lead to drain line clogs and water leaks.

Left unchecked, water collecting around AC equipment can lead to mold growth or electrical hazards. Have technicians identify and address the source of any water leaks right away.
