When the Philadelphia sun is blazing, and the temperature climbs, the last thing anyone wants is an air conditioning (AC) unit that refuses to start. It's a scenario that can turn a comfortably cool indoor retreat into a sweltering nightmare. However, before you let the heat get the better of you or rush to call in a professional, there are several troubleshooting steps you can take to possibly resolve the issue yourself. At McCorry Comfort, we're here to guide you through some common checks and fixes to get your AC unit up and running during the critical summer months.

Verify Power Sources

First things first, ensure your AC unit is receiving power. Check your home’s electrical panel for any tripped breakers or blown fuses that could be affecting your AC unit. It's a simple check that can often solve the problem instantly.

Inspect the Thermostat

A malfunctioning thermostat can lead to your AC unit not starting. Make sure it's set to "cool" and the temperature setting is lower than the current room temperature. If you have a programmable thermostat, verify that it's not set on a schedule that prevents the AC from turning on. Consider replacing the batteries if it's battery-operated or consulting with the experts at McCorry Comfort for a more thorough inspection.

Clean or Replace Air Filters

A clogged air filter can restrict airflow and cause your AC unit to malfunction or not start at all. Check the filter and, if it's dirty, either clean or replace it. This is a simple maintenance task that can prevent a host of issues and improve your system's efficiency.

Check the Outdoor Unit

Sometimes, debris, leaves, or even small animals can obstruct your outdoor unit, preventing it from starting. Ensure there's at least 2 feet of clearance around the unit and remove any visible debris. Also, check for any visible signs of damage or wear.

Inspect the Condensate Drain Line

AC units have a safety feature that prevents operation if the condensate drain line is clogged. This is because water that cannot drain can cause damage to the system. Check the line for clogs and clear them if necessary. This might require professional assistance if the clog is stubborn or the line is difficult to access.

Consider the Age and Condition of Your Unit

If your AC unit is particularly old or has been experiencing frequent problems, it might be time to consider a replacement. The team at McCorry Comfort can help assess your current system and recommend the best course of action, whether it’s a repair or a new installation.

When to Call a Professional

While these troubleshooting tips can resolve some common issues, there are instances when you need to call in the professionals. If you've gone through the above steps and your AC unit still won't start, or if you encounter complex problems like refrigerant leaks or electrical issues, it's time to contact the experts at McCorry Comfort.

Remember, regular maintenance is key to preventing sudden breakdowns. Scheduling annual inspections with McCorry Comfort can help identify and fix potential issues before they lead to your AC unit not starting, ensuring you stay cool all summer long in Philadelphia.
