Properly sizing HVAC equipment is a complex job that relies on careful calculations. A system that’s too large or too small will lead to problems both with home comfort and energy efficiency. If you’re considering a new heating or cooling system for your Canyon, Texas, home, make sure you consult with a professional before making any decisions.

Understanding HVAC Load Calculations

A load calculation is a complex equation used to determine your home’s heating and cooling loads. The cooling load is the amount of heat that must be removed from your home to maintain a particular temperature in warm seasons. The heating load is the amount of heat that must be added to keep the home warm in cold weather.

The Air Conditioning Contractors of America (ACCA) have developed meticulous standards and a detailed method for determining your heating and cooling loads, known as Manual J. Look for a contractor that uses Manual J calculations and not just rule of thumb to size your equipment.

Problems with a Small System

If your system is too small for your home, it won’t be able to adequately heat or cool the space. The system may run continuously without ever achieving the desired results. This puts excessive wear and tear on the unit and leaves you feeling uncomfortable year-round.

Problems with Oversized Systems

It’s tempting to overcompensate, but a system that’s too large won’t keep you comfortable. An oversized air conditioning system will cycle on and off too frequently. It won’t run long enough to properly lower your humidity levels, giving your home a damp and sticky feeling. A furnace that’s too large will produce uneven heating, resulting in uncomfortable hot and cold spots throughout the house. Both systems will cost more to operate than one that’s sized properly for your space.
