Common Air Conditioner Problems and Troubleshooting

You may not think about your air conditioner very often, but it is your first line of defense against sweltering temperatures and high humidity. Cooling equipment is complex, with multiple moving parts that are prone to wear and tear. Your AC unit’s performance may imperceptibly decline until something finally breaks down, or it could suddenly stop working during the hottest day of the year.

From loud AC noises to weak airflow, recognizing typical AC problems and promptly addressing them can save you time, money and frustration. While you might be able to resolve some minor AC issues with simple DIY fixes, others require professional expertise. Use 1st Class Heat & Air’s guide to troubleshooting air conditioner problems to help you understand the difference.

1. Noisy Air Conditioning

A noisy air conditioner is an annoyance, causing daytime headaches and even disrupting your sleep at night. Beyond disturbing the peace, strange AC noises like whistling, squeaking, rattling, shaking or buzzing can also signal underlying air conditioning issues that may lead to a complete system failure if left unaddressed.

A loud air conditioner may indicate anything from loose components to a malfunctioning motor. Ignoring these noises could lead to further damage, so you should call 1st Class Heat & Air for AC repair in Plano at the first sign of air conditioner issues. Our award-winning AC repair team can promptly identify the root cause and restore your home comfort at an affordable price. 

2. AC Evaporator Coil Issues

The evaporator coil performs the integral function of absorbing heat from the air inside your home. Evaporator coil problems such as dirt buildup, leaks or freezing can hinder your AC’s performance over time.

Dirty evaporator coil symptoms include reduced efficiency, higher energy bills and frequent cycling, while frozen coils often cause airflow obstructions or refrigerant issues. Meanwhile, a leaking evaporator coil may lead to significant system damage. Contact our qualified HVAC technicians to address these air conditioner problems safely and effectively.

3. AC Refrigerant Leaks

Refrigerant is vital for the cooling process, and leaks can quickly compromise your air conditioner’s performance. While minor AC leaks might only require a simple refrigerant top off, extensive and recurring leaks demand professional intervention. Our trained, certified and insured HVAC contractors will pinpoint the trouble spot, repair it and recharge your system for optimal cooling capacity.

A leaking air conditioner can indicate more extensive AC problems, such as component wear and tear or improper maintenance. Proactively addressing this issue will keep your air conditioner functioning smoothly and help you avoid costly future repair bills.

4. Air Conditioner Not Cooling

An air conditioner that is not cooling your home properly can stem from various issues, including dirty filters, a malfunctioning thermostat, low refrigerant levels or compressor problems. Start by checking the thermostat settings and ensuring the AC filters are clean. If your airflow remains weak or the issue persists, it’s time to contact 1st Class Heat & Air to schedule a comprehensive AC inspection and repair.

5. Dirty AC Filters

If your AC is not working, clogged filters may be to blame. While routine AC filter replacement is a straightforward task, many homeowners still forget to do it, increasing their likelihood of experiencing issues like restricted airflow, reduced system efficiency and poor indoor air quality.
