Do it yourself remodelers
If you are renovating or remodeling your home, changing the way the air is distributed in your home can affect your comfort and have an impact on your utility bills. Many homeowners are unaware that removing walls, finishing bonus rooms, adding sunrooms, home offices, cathedral ceilings and other structural changes can adversely affect the performance of your existing central heating and air system.
In a nutshell, it’s about balance. For a home comfort system to work properly and efficiently, there has to be a proper balance of incoming air (return) and the air you feel that is cold or warm (supply). Air conditioners are rated to supply a certain amount of tonnage of air (volume) to your home, based upon the way your home is built. It is all about cubic feet of air. That requires a special calculation to be performed.
So if your home requires 3 tons of air going out to cool or heat it, there must be that same amount of air being returned to the system, otherwise the home may have a positive or negative pressure, both which can cause issues to your home, utility bills and the life expectancy of your equipment. Even more importantly, your newly remodeled home will be too warm or not warm or cool enough because your existing unit is now incorrectly sized to accommodate your improvements.
Other things that affect the amount of air needed to insure your system is functioning at the most economical and efficient level include, west facing windows, amount of glass in your home, type of structure, attic ventilation, quality and R factor of insulation, type of glass in your windows, objects that may emit excessive heat, types of ceilings, landscaping, how much of the conditioned space is affected by the grade or the slope of the home (walk out basements), and several other factors, including duct leakage, length of runs, etc.
Many homeowners think that they can just “tap” into their existing system to provide cooling to the basement. Unfortunately, most of the time, this causes more problems. Many basements are humid, damp, dark and providing moist air without adequate distribution can cause issues with mold and mildew, condensation issues and/or a shortage of air to the remainder of the home where you live most of the time.
Depending upon the size of the basement, separate systems are usually advised. A common practice is to install a heat pump, because it is all electric and the basement is usually below ground level making it more insulated and more practical for heat pump utilization.
