Action Air explains a simple answer….
If you have a heat pump, the answer to this question is very simple: NO. Here’s why:
Your heat pump runs all year long and it needs to be able to freely take in air along the sides and release exhaust out the top.
Did you know that your unit has a defrost cycle?
This cycle normally lasts around 15 minutes and works by returning the hot refrigerant back to the outdoor heat pump to melt the ice and snow. You may notice some cool air coming out of your vents while the unit is going through its defrost cycle. This is normal. Just wait 10-15 minutes for the unit to kick back on.
What if I have a gas furnace?
If you have a gas furnace, make sure that your intake and exhaust pipes are free and clear. If your pipes are clogged, this can lead to combustion gases leaking into the home and system shutdown.
Basic indoor prevention for efficiency.
Of course, you already know the basics:
- Change your air filters
- Have your unit inspected semi-annually
