2 Common Cooling Problems With Quick Fixes

Common Cooling Problems and How to Fix Them Quickly

As a homeowner, it’s important to recognize that not every air conditioner issue means your system is about to break down. You can easily fix some common cooling problems without major repairs. Below, we’ve outlined two frequent issues that often cause air conditioning problems and what you can do to resolve them quickly.

1. Blocked or Restricted Airflow

Restricted or blocked airflow often causes your air conditioner to struggle with cooling your home. Your AC system relies on smooth airflow to function properly, so when air is unable to circulate freely, it prevents the system from doing its job.

Here’s how it works: Air enters the air conditioner through the return air vent and is pulled into the system by the blower. If the air can’t reach the coil, the system cannot remove the heat from inside your home, and your AC will blow warm air instead.

Common Causes of Airflow Restrictions

Dirty Air Filters: If you don’t regularly replace your air filter, it can become clogged with dust, dirt, pet dander, and pollen. This thick layer of debris blocks the airflow into the system, preventing the air from reaching the evaporator coil.

Dirty Evaporator Coils: Even with regular filter changes, dirt can still make its way into the system and collect on the evaporator coil. A dirty coil prevents heat from being transferred to the refrigerant, which results in warm air circulating inside your home.

How to Fix Restricted Airflow

The good news is that fixing airflow issues is usually simple. Here’s what you can do:

Change the Air Filter Regularly: Depending on the type of filter, you should replace it every 1–3 months to keep airflow strong. This prevents dust and debris from building up in the system and causing blockages.

Clean the Evaporator Coil: If the coil is dirty, it will need to be cleaned. A professional HVAC technician can inspect and clean the evaporator coil as part of your regular maintenance. It’s recommended to have this done at least once a year to keep your AC running efficiently.

2. Motor Capacitor Failure

Another common issue that can lead to warm air blowing from your AC is a failed motor capacitor. Capacitors are vital components in your AC system that provide a quick electrical boost to the heavy-duty motors, which move the fans and compressor.

When your AC starts, the motor capacitors release a burst of electricity. Thus, helping the motor overcome inertia and start the cooling process. However, motor capacitors are susceptible to failure, especially during hot weather. The constant on/off cycles and heavy electrical load can wear down the capacitors, preventing them from delivering the required boost.

How to Identify Motor Capacitor Failure

If the capacitor fails, the cooling fan and compressor won’t function correctly, and the system won’t cool the air. However, the indoor blower might still work, and you may notice that the air feels warm rather than cool.

You can often identify a failed capacitor by listening to the outdoor unit. If you hear a buzzing or humming sound but notice that the unit isn’t operating. There’s a good chance the capacitor has blown.

How to Fix Motor Capacitor Failure

Replacing a motor capacitor is usually a quick and inexpensive fix. An HVAC technician can inspect the capacitor and determine if it needs replacement. Fortunately, this is typically a straightforward repair that can restore your system’s cooling ability within a few hours.

Common Cooling Problems – When to Call a Professional

If your air conditioner isn’t cooling your home properly, it’s always a good idea to call a professional HVAC technician to inspect the system. While you can easily fix some issues, like dirty filters, other problems, such as a failed motor capacitor or dirty evaporator coils, require expert attention.
