Are there rooms in the home that are warmer in summer and cooler in winter? Balance the air pressure in your house and make your HVAC system perform.
If so, your heating or air conditioning system may be out of balance. When a system is out of balance it uses more energy because it's less energy efficient. Improving a systems performance will improve indoor air quality and add comfort to your living space. Achieve balance with either the Perfect Balance® In-Door Return Air Pathway (R.A.P.) or the R.A.P. wall unit. Both are made in the U.S.A. and THE inexpensive easy to install solution to achieve air balance.
