During colder months, open low returns.

Written by All Comfort Services | October 18, 2018

During colder months, open low returns.

Customer Question: Do I open or close my low return register during the colder months?

Answer: Open low return register during colder months.

Now that temperatures are consistently colder, you likely have your furnace running to heat your home. If your home has ductwork, look to see if you have high and low returns. There will be a lever to open and close on one or both of the registers.

When your thermostat calls for more heat, your furnace blows the warm air through the ductwork and out the vents. Then, the air circulates and warm air rises and colder air sinks. Open your lower registers as illustrated in the video so that the vent passway is closed.

If you have registers that only open or close near the ceiling, then close during colder months and open during summer months. If you have questions, feel free to ask our technician during your next furnace tune-up.
