Q. Could my allergies be getting worse from not changing my HVAC filter?
A. Yes, as your filter gets too dirty its ability to capture and hold particles decreases and more dust and dirt can come through the filter. It’s important to use a good quality filter, typically in the 8-12 MERV range. Below MERV 8 it does not capture enough particles and above MERV 12 it is too restrictive to air flow.
Q. Why does the air from my vent feel cool when the heat pump is on?
A. The HP is designed to heat the air about 20 degrees each time the air goes through the system. A gas or oil furnace is designed for a 40-70 degree temperature rise as the air passes thru the furnace. So if you maintain 70 degrees in the home, a heat pump will put out about 90 degree air depending on the outside temperature. Since the normal body temperature is 98.6 degrees this 90 degree air feels cool to us. In comparison a gas or oil furnace normally warms the air to between 110 - 140 degrees or higher and therefore it feels warm to us.
