Why Your AC Struggles in Houston Heat (and How to Fix It) 

Even though your air conditioner pushes out cold air during every cooling cycle, you might notice that your home still feels uncomfortably warm. There are a few reasons your system might struggle to keep up with your cooling needs.


While an older system might need replacing, AC repair in Magnolia, TX, can restore effective cooling power to a newer system.


Your Air Conditioner Can’t Compete With Triple-Digit Temperatures

On extremely hot days, your air conditioner just can’t keep up with cooling needs. Manufacturers design the system to provide a climate that’s up to 20 degrees cooler than the outdoor environment. That ratio becomes more difficult to maintain when the outside temperature exceeds 100 degrees.


On excessively hot days, you may need to close your curtains and run ceiling fans to lighten the burden on the AC system.


Your AC Might Have a Refrigerant Leak

A heavy refrigerant leak will drain enough refrigerant from the system to cause cooling problems. In that case, you’ll feel warm air coming from the air conditioner.


A smaller leak won’t produce that drastic change right away. Instead, the system will struggle to maintain a consistent temperature while still producing cool air. If you suspect a minor leak, schedule AC repair in Magnolia, TX.


Your Air Filter Needs More Frequent Changing

As dirt and other contaminants get trapped in the air filter’s fibers, cool air will move more slowly through the filter. This inhibits the cooling process and reduces the system’s ability to maintain a consistent indoor temperature.


In addition, the system will use more energy as it tries to cool your home. Monthly air filter changes usually solve this problem.


Your Coils Need Additional Service

During an annual tune-up, your HVAC technician will clean the evaporator and condenser coils. One cleaning per year is usually enough, but the coils might collect more contaminants when you subject the system to heavier use.


When expecting an extremely hot period with multiple days over 100 degrees, scheduling additional coil cleaning will help the system run more efficiently.
