The Best Invention Of The Last 75 Years (NAPSA)—The most influential innovation of the past 75 years wasn’t the cell phone. It wasn’t the personal computer. It wasn’t even television. It was air-conditioning. That’s the finding of an online poll conducted by AOL and The Henry Ford historical institution. Since air-conditioning is so important, homeowners should consider several factors before replacing an old system. The experts at York Heating and Cooling recommendhiring a licensed contractor to evaluate the home heating and cooling system and make recommendations for a new system. The inspection should include: Making sure the ductwork was installed properly and sized correctly Ensuring the unit is operating properly andefficiently Checking to ensure that filters are properly sized and clean Ensuring that the refrigerant lines provide unrestricted flow and are the right size.

If the air-conditioning unit is properly sized, it will experience longer run times at design conditions, providing better cooling and dehumidification and lowering energy bills. When purchasing a new system, it is also important to check the unit’s seasonal energy efficiency ratio (SEER) and to take a look at what energy-saving features it may havebefore purchasing it. The higher the SEER number, the more energyefficient the unit is and the more money homeowners will save on their utility bills. Another thing to look for is the Energy Star label, which identifies the most efficient units available in the market.
