Common Reasons Why Your AC Is Not Blowing Cold Air

When summer temperatures soar into the triple digits, the last thing you want is for your AC unit to go on the fritz, leaving you sweating it out and sleeping in the basement until you can get a technician to your home.  During a heat wave, it could take days to get service that restores your HVAC equipment and the cool interior you prefer.

When you understand typical reasons why your AC isn’t working as it should, you may be able to address the problem on your own, or at least take steps prevent common issues from arising.  Here are just a few of the most common reasons why your AC may not be blowing cold air. 

Check Your Settings

Programmable thermostats are a modern marvel.  They allow you to set a schedule for heating and cooling that takes your daily routine into account and helps you to reduce energy waste.  You can lock them to keep kids from cranking the air, and some even offer remote control options with mobile apps.

Unfortunately, it’s easy to get confused with so many settings to choose from.  It’s possible that you accidentally set your AC to “on” rather than the “auto” setting.  What does this mean?  It means your air is running constantly, whether your home needs cooling or not.

With the auto setting, your equipment will turn off when the set temperature is reached and kick on again when sensors detect that the environment is too warm.  If the air is running constantly, it will simply produce less cold air in a bid to maintain the set temperature, and it could even blow warm at times.  Switch to auto and see if that helps before you schedule an emergency HVAC service.

Service Your Unit

Regular servicing is the best way to prevent issues with your HVAC system, including common causes of AC failure.  A lack of cool air when you turn on the AC could be related to clogged filters, dirty equipment, or an evaporator coil that freezes.  With regular HVAC servicing to clean, inspect, maintain, and repair your system, you shouldn’t have to worry about a slew of common problems.

Refill Refrigerant

Over time, the refrigerant that keeps the cool air pumping can become depleted.  As long as there isn’t a leak, this is a simple fix.  Your HVAC technician simply has to prime the refrigerant to restore your air to the chill temperature you desire.
