5 Signs That You Need to Change Your AC Filter

- The Air Isn’t Cold Enough.
- The Electricity Bill Has Increased.

What happens if you never change your HVAC filter?
If you don’t change your AC filter, it will begin to fail. It will no longer be able to filter the air properly, letting dust and contaminants get into the AC. Dust jams the moving parts of an AC such as fan motors and valves. This is how dust makes the unit less energy efficient (at best) and can lead to breakdowns.
Is no air filter better than a dirty one?
Running your air conditioner without a filter is worse than running it with a dirty one. Instead, get to the store as soon as possible for a replacement or call an HVAC professional for replacement. Without a filter, your air conditioner is at risk for severe and expensive problems.
Does air filter affect AC in house?
A dirty air filter restricts the flow of cold air, causing it to build up inside the air conditioner and lower the internal temperature. Uneven Cooling: Even if it’s not enough to cause freezing, that restricted airflow isn’t good for your air conditioner’s cooling power.
Can Dirty air filters make you sick?
If the filter’s dirty, everything past the filter is dirty too, including the air you breathe. This pumps your home full of dust and allergens. Speaking of allergens, they can cause a number of physical symptoms like headaches, fatigue, tightness in your chest, and a mess of cold symptoms you may not be able to shake.
What happens if air filter is backwards?
By installing your filter backwards, air will have a harder time flowing through the filter and your air handler will have to work harder to make up for the loss of airflow. This could lead to higher utility bills and possibly damage your furnace or air conditioner.
How often do you clean AC filters?
As a general rule, you should clean your air conditioner filters within the indoor unit every two weeks. In more dusty or polluted environments you should clean your filters more regularly. Cleaning your filters is the most important maintenance task you can do to care for your air conditioner.
Is it OK to run HVAC without filter?
The short answer: You can get away with running your AC without a filter for a short amount of time without hurting your system. That being said, running your AC without a filter for longer than 6-8 hours can cause serious damage to your AC system and significantly lower the quality of the air in your home.
Will AC stop working if filter is dirty?
As a result of the buildup, a dirty filter will also cause poor cold airflow in your air conditioning system. That cold air will be trapped inside your air conditioner, causing ice to form on its coils. Once that happens, your air conditioner will freeze up and become inoperable.
