What is a central air conditioner?

Central air conditioners circulate cool air through a system of supply and return ducts. They are generally more efficient and long-lasting than window AC units, and can be more cost effective for cooling multiple rooms. A central air conditioner is either a split-system unit or a packaged unit.

How often do I need AC maintenance?

A new AC unit usually requires an annual maintenance and inspection at the beginning of summer. An HVAC technician can perform preventative maintenance and tell you whether your unit has any issues during this visit.

What is a good noise level for your air conditioner?

Air conditioner noise levels are measured in decibels, or dBs. While the optimal noise level for your air conditioner comes down to personal preference, this handy list can help you understand just how loud a system you’re considering might be. Use this information to determine the air conditioner noise level you would feel comfortable having in your home or yard. Most Trane air conditioners fall in the 55-75 dBA range, which are the equivalent of a quiet conversation and a vacuum cleaner.

What size AC unit do I need?

A Manual J calculation is the best option to determine your ideal size HVAC system. This calculation takes into account climate zone, usage, square footage, layout, height of ceilings, number of windows, shade, ductwork, insulation, and several other factors. A simpler estimate can be done using just square footage of the house, with one ton of capacity generally covering 500 square feet of home area.

Do I need AC repair or AC replacement?

The answer will be different for every homeowner based on the age and usage of your current system, your home's climate zone, and how regularly the system received maintenance. If you do plan to replace your air conditioner, consider the correct size, SEER2 rating, cooling stages, noise level, and cost.

How does AC work to cool my home?

Your central air conditioning unit draws heat energy out of the house and transfers it to the outside air. The most common setup for air conditioning units for homes is a split system, which includes an inside-the-home evaporative heat exchanger and an outside condensing unit heat exchanger.

How long do AC units last?

Most air conditioning units last around 15 years. Some units can last longer if properly maintained and they are quality units to begin with. Some units may not last as long if they are not properly maintained, if you use them year-round, or if they are a lower-quality unit. Lifespan also depends on your home's energy efficiency and your local climate.

How do I know what refrigerant is in my air conditioner?

For existing AC and heat pump installations at your home, your owner’s manual will say what type of refrigerant it uses. If the unit was manufactured in 2010 or later, the refrigerant will be R-410A. If it was manufactured before 2010, the refrigerant would be R-22, which is no longer in production. You may want to consider system replacement due to the age of the unit.
