It isn’t uncommon for Roswell homeowners to find out that the current air conditioning system in their home isn’t the correct unit for the size of the house. They may not have realized the issue until the current AC unit breaks down or is reaching the end of its life cycle and is no longer efficient to operate compared to new units on the market.
The issue with incorrect AC size can happen for several different reasons. A common issue is a home that has been renovated or expanded to include additional square footage. Another issue can occur when the last owners had to replace the system and simply chose an air conditioning unit that was on sale, even if it wasn’t the ideal size for the home.
Regardless of why the incorrect size of the system was installed, during a replacement the issue can be corrected, allowing for greater efficiency, better cooling potential and a system that will last longer as it is not constantly cycling on or always running.
While there are recommended sizes of air conditioning units based on the square footage of the home and the climate zone, there are other issues to consider as well. Having an Atlanta HVAC service come out and complete a home evaluation will ensure the correct tonnage for the system. One ton represents the ability of the AC system to cool 12, 000 British Thermal Units (BTUs) in one hour.
Getting an air conditioning unit that is too large is energy inefficient as it will constantly come on and then immediately cycle off. The most energy is used when the system cycles on so that it will increase your bills. For Roswell homes with an undersized AC unit, the system simply runs all the time, likewise increasing the cost of operation as it never cycles off.
