Total Comfort. Total Savings. TOTAL AIR!


Size Does Matter


Before you even consider efficiency ratings, price and features of a new furnace and refrigerated air system, you must start by determining the size of unit you need for the space you want to cool. Ensuring that the right size heating and cooling system installed is critical to providing consistent indoor comfort for you and your family. Sizing units to your home is best left to the professionals at Total Air. Our project managers are specifically trained and you can rest assured knowing that you are buying the best size system for your home when their calculations are complete and recommendations are made.

Size of system is most important for saving energy, which can be wasted by either a too-large or too-small system. If you buy an air conditioner that's too small, it will continuously run and struggle to cool your home. Buy one that's too big will cool so quickly that it doesn't have time to remove humidity and moisture in the air, leaving you with a cold, clammy and uncomfortable space.

A number of issues can occur when your heating or cooling system is the wrong size for your home. Consider these:

A system that is too large will:
• use more energy than is needed simply because it takes more power to run a larger system.
• turn itself on and off repeatedly and run for only a short time. This is called short-cycling.
• create noise as excess air moves through the air ducts because the system is more powerful than is needed for your home.
• create large temperature swings.
• require the system to work harder and less efficiently. This will shorten the life span of the system.
• fail to provide adequate humidity control.

A system that is too small will:
• runs continuously yet never fail to maintain the proper temperature and comfort level — especially during extreme weather.
• keep your home too hot in summer and too cold in winter.
• require a supplemental form of heating or cooling to keep you comfortable.
• eventually malfunction since it runs continuously
• mean more breakdowns since it will tend to be a bit overworked.

A system that is properly sized for your home operates at optimal efficiency, saving you money on energy costs and keeps your indoor temperature and overall comfort level more consistent. Properly sized systems also provide the proper humidity control lowering the likelihood of indoor air quality problems. Noise levels are minimized and with regular maintenance, the new system will likely run long after the warranty expires.

In short, the capacity of your equipment NEEDS to match the size of the home being heated or cooled.
