Clogged Filters

When was the last time you changed your filter to your AC unit? Air flow is required for your AC to properly work, when filters aren’t changed properly, it can actually impede the flow of air, making the system work harder even though it is producing little to no cold air.

We recommend changing your filter at least once a month unless otherwise specified. This prevents your filter from becoming clogged and will ensure your system can work best as possible.

Closed/Blocked Vents

Have you closed some of your vents or blocked them without noticing? Many times during winter, people will close their vents and forget to open them back up. This can impact air flow, leading to your system not producing the proper cool air it should be.

We recommend walking around your home and making sure no vents are closed or blocked by any furniture.

Leaky Ducts

Sometimes what is causing your warm air can be hidden. Sometimes your ducts can have holes, cracks or even be completely disconnected. When this occurs, air can’t flow properly through the system, leading to performance issues and warm air.
