One of the most straightforward fixes when you need to balance the HVAC in your house is to check the air filter! If you have used your HVAC for an extended period of time and never changed the filter in your central unit, this could be the culprit for not getting enough heat or air into an area of your home. 

How Often Should I Change the Air Filter In My HVAC?

You might wonder how often you need to change the air filter in your home. Unfortunately, there is not only one answer that applies to every home. Some of the conditions that can determine how frequently you need to be changing your air filter are: 

  • How much pollution there is in the area you live in. 
  • Whether or not you have animals in or around your house. 
  • If you keep your windows open a lot or not. 
  • The type of air filter that you use. 

Regardless of these factors, it is a good idea to check your air filter frequently, and it should always be one of the first things you look at when you balance the HVAC in your home. Ensuring that you have a clean filter is one of the more straightforward solutions when balancing the HVAC in your house.

4. Check for Any Gaps Along the Duct Work 

When you are in your basement or looking at the HVAC system in your home, it is a good idea to look around at your ductwork and ensure there are no gaps or leaks from where they attach to the main unit. 

It is common in many homes that the metal chambers are connected to wood, which is not always going to give an adequate seal to prevent air from being lost. This excellent video by Columbia Water and Light shows how a simple roll of tape can help you balance your HVAC system!

5. Adjust the Dampers

The most important aspect of air balancing your HVAC is to adjust the dampers. For example, some homes have HVAC systems installed without any dampers. In this case, you would want to hire someone to install dampers for you or attempt to do it yourself. 

But in most homes, the ducts have dampers you can adjust, generally with the turn of a knob from the exterior. Opening or closing the dampers is similar to moving the register to increase or decrease heat or air conditioning in a room. 

The advantage of adjusting the dampers instead of the heat register is that you close or open the duct near the HVAC unit. This proximity gives a more efficient airflow than waiting to block it with the register. 

If you are unsure which dampers should be open or closed, you can perform tests or hire a professional to test the ducts for you. This will give you more accurate results when balancing the HVAC in your home.
