Have you noticed that some of the rooms in your home are always hotter or colder than others no matter what you set your thermostat to?
First, check for these common problems:
- Dirty air filter—A dirty filter restricts airflow, not letting your home get enough cool air.
- Closed vents—Closed vents in rooms can cause them to be hotter than other rooms.
- Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home.
- Air duct issues—If you have any kinked or crushed supply ducts, certain rooms won’t get enough air. Also, leaky ducts cause a host of problems, including uneven temperatures. Here’s how to tell if your ducts are leaking.
If it’s not one of the problems above, the next likely cause is an unbalanced air conditioning and heating system. You’ll need an AC company to balance it.
What is air balancing?
Air balancing is the process of adjusting the amount of cooled and heated air each room in your home gets.
In a perfectly balanced system, every room in the home would reach the same temperature at exactly the same time. A home with very different temperatures in different rooms is said to have an unbalanced system.
Causes of an unbalanced system (and how to fix them)
Many different things can cause your air conditioning and heating system to be unbalanced.
When an air conditioning system is installed, larger ducts and more supply vents are used to get larger volumes of air into the rooms that need it.
Proper duct installation gets your system pretty close to balanced. Dampers are then used to fine tune the airflow and provide even temperatures throughout your house.
Dampers are valves that let you accurately adjust the amount of air going to each room or part of the house. They are installed on the main ducts near the inside unit of the air conditioner (usually in the attic or a closet).
