Think about the last time you replaced a central air conditioning system.  If you haven’t already, this blog is still for you.

As a system ages, it gradually loses its cooling capability, and you forget how well it performed when it was new. All you know is that it’s not getting the job done now, you’re constantly lowering the thermostat to compensate and, no matter what you do, no one in your home is comfortable.  At least not like before.

So, what’s a home owner to do? Well, it’s logical to conclude that maybe your 3-ton system is no longer up to the task and a new and larger system is what’s called for. Logical, but not necessarily accurate, because it’s just as likely that the system you’re replacing was over-sized.

Either way, a system that wasn’t correctly sized is going to under perform.  An over-sized system, for example, will cycle on and off more frequently than it should have to.  That leads to added wear and tear, higher energy bills, and a shorter system lifespan.

Under-sizing is equally troublesome.  It causes an AC system to run longer to properly cool your home.  Different mistake, same end results, and none of them desirable.

Here at Burton, we take all factors into account to ensure your system is properly sized.  These include:

  • Size, shape, and orientation of the house
  • Amount and placement of insulation
  • Window area, location, and type
  • Air infiltration rates
  • The number and ages of occupants
  • Occupant comfort preferences
  • The types and efficiencies of lights and major home appliances that give off heat
