“Help! My Cooling System is Not Cooling”

man in front of fan looking hotOne of the best ways, if not the best way to prevent air conditioning repair San Antonio needs is to schedule routine preventive maintenance before your cooling system’s heaviest period of use. So that means you’ve hopefully already had your tune-up performed this year. Without regular maintenance, you may find yourself facing any number of potential cooling system malfunctions, which we’ll cover below. The result of such malfunctions can be anything from low airflow or a noisy system to an AC that doesn’t actually cool—its only job!

Ensure the Efficiency of Your Cooling System

Before we get to why a cooling system might not actually be cooling your home, we want to cover some easy ways to ensure that your air conditioner operates as efficiently as possible:

  • Make sure your thermostat is operating as it should and correctly reading the temperature in your home.
  • Upgrade your thermostat to a digital or programmable model if you haven’t already.
  • Have your air ducts checked for damages.
  • Improve upon your home’s insulation to reduce heat gain from the outdoors.
  • Limit the use of heat-producing appliances during the hottest parts of the day.

Following these steps and staying on top of your annual maintenance appointment can help you avoid this “no cooling” issue altogether. But if you’ve run into this issue nevertheless, here are a few reasons why it might be happening:

A Refrigerant Leak

A system that’s blowing out air, but not cold air, could be leaking refrigerant. There’s a pretty common misconception that refrigerant “runs out,” like fuel in a car, and needs to be refilled (“recharged”) on a regular basis. This is a dangerous assumption to make.

A loss of refrigerant means there is a leak in your air conditioner. This leak must be located and repaired at the source. This will ensure that you don’t experience the problem again, and will restore the cooling effectiveness of your air conditioner.

If you’ve ever been told by a service “professional” that losing refrigerant is a normal part of the cooling process and you have to have your system recharged regularly, then we’re sorry to say you aren’t dealing with an honest professional at all.

Blocked Airflow

Perhaps your air is as cool as it should be, but you aren’t getting as powerful airflow as usual. As a result, you may think it doesn’t feel as cool in your home. Blocked airflow can be caused by a clogged and dirty air filter. The air filter that comes with your HVAC system is there to protect the inside components of your HVAC system form dirt, dust and other debris—though many people think it’s there to protect indoor air quality.

So when the air filter is too dirty, it restricts the airflow of your system. This is not only a frustrating problem to have, but a potentially damaging one. Low airflow causes your air conditioner to work harder than it should have to in order to do its job. Fortunately, changing your air filter is something you can (and should) handle on your own, every 1-3 months during periods of system use.
