The Importance of HVAC System Sizing

Here’s a situation many homeowners face every day.

You’ve had a heating or cooling system for so long, you can’t remember how effective it was when it was first installed. All you know is that it’s much older now and not doing its job. Then you think more about it and realize it never lived up to its expectations. At that point, you might think: “It must be too small.  Next time, we’ll go bigger!”

While that might very well be the case, it’s just as likely the system was over-sized for your home and heating needs.

The Benefit of Proper System Sizing

Here at GBT Heating & Cooling, we don’t guess at the number of BTUs an AC system should have or what might be the right size for a new furnace. We take measurements that include ceiling height, square footage, number of occupants, ductwork size and integrity, and more.

When all relevant factors have been considered, we will have established your home’s “load requirement” which refers to the amount of heating and cooling needed to maintain the desired comfort levels. A right-sized HVAC system meets the load requirement of a space without being too big or small.

In addition, proper sizing leads to less wear and tear on your HVAC system caused by more efficient operation.

An over-sized system will heat or cool your home quickly but will spend most of its operating time in the startup cycle. That puts added strain on the system and limits its ability to efficiently deliver warm or cool air.

Systems that are too small will waste gobs of energy as they attempt to maintain the desired comfort level when they already are at a size disadvantage.
