Common AC Problems and Their Solutions

Even the most reliable air conditioning units can experience issues over time. Recognizing the common problems can help homeowners and business owners understand when it’s time to seek professional help.

• AC Blowing Warm Air: If your air conditioner isn’t cooling properly, several factors could be at play, including low refrigerant levels, a clogged air filter, or a failing compressor. Our technicians at Stewart Heating Plumbing Air Conditioning perform thorough diagnostics to pinpoint the problem and restore optimal cooling performance to keep your home comfortable.
• Strange Noises Coming from the Unit: Unusual sounds like banging, grinding, or squealing often signal problems with the fan motor, compressor, or loose components. Ignoring these noises can lead to further damage and costly repairs. Our expert team will assess the issue and perform the necessary repairs to prevent system failure and extend the unit’s lifespan.
• Poor Airflow: Uneven cooling or weak airflow is commonly caused by clogged air filters, blocked ducts, or a malfunctioning blower motor. These issues reduce efficiency and strain your AC system. Our technicians will clean or replace filters, inspect ductwork, and ensure proper airflow, so your AC delivers consistent cooling throughout your home or office.
• AC Won’t Turn On: A non-responsive AC can be due to a faulty thermostat, electrical failure, or a damaged capacitor. Our professionals will quickly diagnose and resolve the issue, whether it’s a wiring problem, sensor malfunction, or a failing internal component. We work efficiently to restore your cooling system as soon as possible.
• Water Leaks Around the Unit: Excess moisture or water pooling near your AC often results from a clogged condensate drain, frozen evaporator coils, or a refrigerant leak. If left unaddressed, these issues can lead to mold growth and system damage. Our expert technicians will clear blockages, inspect coils, and ensure proper drainage to prevent further complications.

Our experts accurately detect leaks, seal them to prevent further loss, and recharge your system to manufacturer-specified levels. Proper refrigerant levels restore optimal cooling performance and energy efficiency, keeping your home comfortable.
• Compressor and Motor Repairs: If your AC struggles to start, overheats, or makes unusual noises, it may indicate a failing compressor, fan motor, or capacitor.
