Here’s Reasons Why You Shouldn’t Block Your Cold Air Returns

Here's Reasons Why You Shouldn't Block Your Cold Air ReturnsYou might not like how your cold air return vents look, but covering them up with furniture or drapery could prove costly in the long run.

Those unsightly vents are actually an essential part of your air conditioning system. On a typical central A/C system, the indoor unit relies on the air inside your home to operate normally. Without a steady flow of indoor air, it becomes much harder for the system to keep your home cool and comfortable.

To understand the importance of keeping your cold air returns clear of any obstructions, here’s what could happen if you keep those vents blocked:

  • Individual components, like your blower fan motor, must work harder to overcome airflow restrictions caused by cold air return blockages. In turn, these components will start using more energy to handle this hard work, resulting in a significant increase in your home’s energy bills.
  • The evaporator coil inside your A/C unit relies on a steady stream of warm air to operate properly. Without this airflow, the evaporator coil’s surface temperature can drop below freezing, allowing ice to form on the coil. A frozen coil can prevent your A/C system from cooling your home effectively.
  • Over time, the stresses associated with combating blocked cold air returns can take a serious toll on your A/C system. Breakdowns may become more common and you’ll eventually find yourself in need of an A/C system replacement.

These are just some of the reasons why you shouldn’t Block your cold air returns. To learn more or if you need A/C service in the Greater Cleveland area, contact us at Geisel Heating, Air Conditioning & Plumbing today.
