By now you’ve probably heard about the many benefits of central A/C in your home.


Central air conditioning systems use an outdoor condensing unit to circulate refrigerant through copper piping that leads to an evaporator coil inside an air handler in your home. The air handler also contains a blower unit that moves air over the cooled evaporator coil. It then distributes and circulates that air through a series of supply and return ducts throughout your home.

Residential central air conditioning systems have an average life expectancy of 15 years. These days, newly built homes are often equipped with central air, unlike many older homes. Glasco can not only replace your aging A/C systems, but we specialize in retro fitting central air conditioning into your home by running the ductwork in attics and/or basements with openings in each room for the vents and registers.

When adding A/C to an existing home, sizing your new system properly is very important. The experts at Glasco will size, design and layout your air conditioning system for optimum comfort and efficiency.

Over the last 20 years, many improvements have been made to central air conditioning equipment. The kind of refrigerant that was used for many years (R22), has been phased out and replaced with a more environmentally friendly refrigerant, commonly known as 410A. Simultaneously, great strides have been made in energy efficiency.

Energy Efficiency of Central A/C

If you have been researching central air conditioning, you may be familiar with the term “S.E.E.R. rating,” which refers to the energy efficiency of your air conditioning system. Around the year 2006, the minimum S.E.E.R. in the US increased from 10 to 13. However, Energy Star Standards were 14.5 S.E.E.R at that time.

Today, the minimum efficiency is still 13, but the energy star standard is now 15. However, you can buy a system that has an S.E.E.R. rating as high as 25. You can expect about a seven to 10 percent reduction in energy costs for every S.E.E.R. rating you increase when you replace your old, inefficient air conditioning system.

Keeping your systems clean can also affect efficiency. Changing filters, cleaning condensation drain lines and cleaning the outdoor condenser regularly will help your system run at optimum efficiency. We recommend you have your system checked annual by a professional who can also catch potential problems before they become emergencies. See our Service Page for more information about maintenance and service of your HVAC system.
