DIY Tips for AC Troubleshooting: A Guide from Economy Heating & Air

Nothing can be more inconvenient than a malfunctioning AC unit, especially in the sweltering summer months. While it’s always recommended to call professionals like us at Economy Heating & Air for major issues, you can try a few simple DIY tips for AC troubleshooting before reaching for the phone.

Ensure Your Thermostat Is Correctly Set

This might seem overly simple, but sometimes the issue is as straightforward as an incorrectly set thermostat. Ensure it’s switched to “cooling” mode and check if the temperature is lower than the current room temperature. If your thermostat is programmable, ensure the schedule aligns with your needs.

Check Your Circuit Breaker

If your AC unit isn’t powering on, it may be due to a tripped circuit breaker. Check your home’s electrical panel. If the breaker assigned to the AC unit has tripped, reset it. However, if it trips again shortly after resetting, this could indicate a more serious issue, and it’s time to call the professionals.

Change Your Air Filters

One of the most common AC problems stems from a clogged air filter. If your AC is running but not cooling effectively, it may be due to blocked air filters that limit airflow and reduce the system’s efficiency. Regularly changing your air filters (generally every 1-3 months, depending on usage and type of filter) can prevent this issue.

Inspect Your Outdoor Unit

Over time, debris, such as leaves or grass clippings, can obstruct your outdoor unit, limiting the system’s ability to dissipate heat effectively. Clean around the unit and trim any overgrown foliage to ensure adequate airflow.

Examine the Condensate Drain

Air conditioners remove moisture, typically draining away through a condensate line. If this line becomes clogged, it can cause water to back up into your home or result in the system shutting down to prevent water damage. Check the condensate line for any blockages and gently clear it out if necessary.

Check the AC Vents

Ensure that all vents in your home are open and unobstructed. Sometimes, furniture or curtains may block the vents, impeding the airflow and affecting the cooling efficiency. Ensure all vents are clear and clean for the AC to circulate air properly.

Check Your Coolant Levels

Low refrigerant levels can reduce your AC’s cooling ability. If you notice your system is struggling to cool the air even with good airflow, it might be due to low coolant levels. Checking the refrigerant level requires specialized tools, so while this is something to be aware of, you should reach out to a professional to perform this check safely.

Remember: Safety First

Always ensure your AC system is turned off at the thermostat and the breaker before performing any checks or maintenance. 

While these DIY tips for AC troubleshooting can resolve minor issues, they’re not a substitute for professional maintenance. Your HVAC system is a complex machine that requires expert care to operate at its best.
