Is Your AC System Correctly Sized?

Thinking about buying a new or even your first central AC system?  Then no doubt you’re wondering, among other factors, just how big and powerful it should be.

Let’s say, for example, that it’s time to replace your current 3-ton system, the one that can barely get your interior to 75 degrees, never mind anything more comfortable than that. In that instance, it’s easy to assume that your system is under-sized and for the kind of comfort you want and need, your next system might have to be bigger still.  When, in fact, maybe it was oversized, to begin with, which first led to a gradual decline in efficiency and then its early demise.

We’ll go so far as to say correct system sizing and installations are more important than the brand you purchase. There are plenty of good brand names to choose from, and each of them has “good, better, and best” choices.” But even the best among the best will prove less than satisfying if your system is over-or under-sized.

You see, either way, an incorrectly sized AC system will end up working harder than it needs to meet your temperature demands. An oversized 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.

Equipment under-sizing is no less of a problem as it causes your new system to run longer to properly cool your home. Different mistakes, same end results, and none of them desirable.

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

  • Local climate
  • 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

And that’s just part of the sizing process. So to make sure you get all the AC system you need – no more but no less – contact DiBiase today for a free in-home consultation and a new system proposal. It’s the smart and efficient way to improve your family’s indoor comfort for many years to come.
