Why You Shouldn’t Be Using Your Registers For Temperature Control
In today’s world, our homes are bigger than ever before. Three, four, even five bedrooms are now the norm. We have guest rooms, entertainment rooms, even craft rooms where we store our favorite hobbies. And that takes a lot of heat and air to ensure every room is kept at the proper temperature.
When the thought of controlling your energy costs crosses your mind, it’s only natural to turn to the rooms you don’t use very much. Why heat or cool a room rarely used? Why not turn the register off and only use your HVAC equipment in the space you’re in every day?
It may sound like a great idea, but the solution isn’t as straightforward as that.
When your HVAC system was installed, it was designed to heat and cool a certain amount of space. And when you close off a register, you’re telling the system the number has changed. The equipment doesn’t understand that, so it continues trying to provide the same airflow as before. And that raises the pressure in your system.
Over time, it causes your equipment to work harder than it was designed. It’s trying to operate outside of its guidelines, and it has to overcompensate somewhere. That means the equipment will wear out quicker, cause more problems, and need more repairs.
If you have a single speed motor, it tries desperately to keep up and maintain proper airflow. When it can’t, it means less airflow to all the rooms in your home. And that affects your comfort level, making the rooms you do live in hotter or colder than you’d prefer.
If you have a variable speed motor, it can cause your equipment to work at the higher speeds for longer periods of time. Variable speed equipment is designed to only work at the level needed. But if it’s working full force trying to overcome the difference, it negates any benefits you would normally see by operating at lower speeds.
And this is just the start of potential problems. When equipment begins to work harder and longer than needed, it’s at increased risk for other problems. It can cause duct leaks throughout the system. It can freeze the coil or break the compressor sooner than expected. All of which cause you added expense sooner than you anticipated.
If you’ve noticed a problem with the way your HVAC system currently operates, or if you’re looking for ways to save money on your energy bills each month, the best place to start is with an energy audit. Ask your HVAC contractor about the best places to make improvements to see noticeable differences.
