A new HVAC installation is an investment that rewards you with many years of comfort. To reap the full benefits of your new system, however, it’s critical to correctly size the equipment. Improper installation can lower efficiency by up to 30 percent, resulting in higher energy bills and a shorter system life. A system that’s too big or too small plays havoc with your comfort too. Learn why it’s so important to land in the Goldilocks zone when sizing your heating or air conditioning system.
A Ton of Comfort
When it comes to HVAC systems, the term “ton” has nothing to do with weight. The measurements used to size the systems date back to a time when keeping things cool required daily deliveries of ice. When mechanical refrigeration systems were introduced, their cooling capacity was defined by the tons of ice they could replace. Today, the unit ton is used in air conditioning to calculate heat absorption. The amount of heat the system can remove is measured in British Thermal Units (BTUs). One ton of cooling is equivalent to 12,000 BTUs per hour.
Why Big Isn’t Better
While an oversized system has all the power it takes to keep you comfortable, it often falls short on performance. An air conditioner or heat pump that’s too large tends to cycle off before the cool air can circulate through your home. Because they extract moisture as well as heat from the air, oversized cooling systems don’t have time to remove moisture which raises humidity levels indoors. An undersized system is just as problematic. In the winter, a too-small heater will run overtime trying but failing to maintain comfortable temperatures.
