How to Balance Out the Temperature in Your Home– PART TWO
Common Sources of HVAC System Imbalance
Does it feel like the temperature in your home varies from room-to-room? If you’ve noticed that some areas in the house are considerably cooler/warmer than others, this isn’t normal. While some may blame an old house for spotty heating, it could be a sign that you need to balance out the temperature in your home.
You expect your entire home to be comfortable, but over time an HVAC system imbalance can be caused by many factors. If it’s not one of the common problems mentioned in our previous Blog post How to Balance Out the Temperature in Your Home– PART ONE, the next likely cause is an unbalanced air conditioning and heating system…
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. You’ll need an experienced HVAC company like Bi-County Inc to balance it.
Many different things can disrupt your heating system and air conditioning system and cause unbalance. When an HVAC system is installed, ducts and supply vents are used to get larger volumes of air into the rooms that need it. Proper duct sizing and 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.
Your Heating Isn’t Consistent Throughout Every Room
- MULTIPLE LEVELS – Multiple floors of a house are difficult to balance properly because you must account for heat rising and long runs of ducts needed to get warm/cool air into all the rooms. The best solution to this problem is usually a zoned HVAC system. Zoning breaks up your home into different areas with individually controlled thermostats or temp sensors. You can use zoning to even out the temperature in your home by setting different temperatures for different rooms as needed.
- LONG RUNS OF UNINSULATED DUCTS – Hot air traveling through ductwork in unconditioned areas like your attic will lose heat. Therefore, long runs of uninsulated ducts will leave rooms farther away from the furnace much cooler. Conversely, rooms closer to the source will be much warmer. Fixing this problem could be as simple as adding insulation to your duct work.
- INADEQUATE RETURN VENTS – Many large homes have only a single return vent, which can’t adequately suck in the cold air from more distant rooms. So you have lots of warmed air mixing with cooler air. To help improve return air flow, try leaving the doors to all of your rooms open. Otherwise, you may need to add more return ducts to your home.
- WRONG SIZED SYSTEM – An HVAC system that’s too large may shut off too quickly, leaving some rooms too cool or warm. If this is the case, try using fans to circulate the warm air to cooler rooms in your home. A system that’s too small may never actually be able to cool the entire house adequately. If so, you may need an additional system or a larger capacity system (if your current set-up is ready for retirement).
- ROOM USE – How you’re using the room might cause unbalanced in our system. For example, your home office may be warmer because it contains computers, a server and other electronics that produce heat. Many of these problems can be solved by adjusting the airflow to your rooms using dampers in the ducts.
- HOME ADDITIONS & RENOVATIONS – A remodel done by you or a previous homeowner may have upset your HVAC system’s balance, especially if rooms were added and walls were added or removed. If the problem is minor, you may be able to fix it by adjusting the dampers in your ducts. In the case of some home additions, you may need to run additional ducts to solve the problem. Or you may need an additional or a larger capacity system.
