Properly Sizing HVAC Units

Learn the How & Why From Your HVAC Experts

Whether it is a cool, fresh atmosphere in the hot summer or a cozy, toasty environment in the harsh winter – your HVAC unit is instrumental in keeping your home and family comfortable at all times. There are several considerations that can make or break your heating and cooling system and proper sizing is one of them. From rising electricity bills to extreme humidity or dryness in the air, incorrect sizing issues can cause many problems. The home comfort specialists at Bi-County Inc offer some insights into properly sizing your HVAC units.

Enjoy Efficiency & Comfort with the Right Sized HVAC Unit

Whether you are upgrading your existing HVAC system or installing a new one, incorrect sizing of the unit may lead to problems with:

  • Temperature Consistency & Comfort: If you select a unit that is too large for the size of your home, the excess capacity would lead to frequent thermostat shut-offs and constantly fluctuating temperatures. Moreover, since the cycle does not run long enough to dehumidify the air, you may end up feeling uncomfortable due to the excessive mugginess.
  • System Performance: An under-capacity unit will mean inadequate heating or cooling. The system will constantly be trying to keep pace with the external temperature to reach the desired internal temperature. That would lead to excessive wear and tear of the components and constant use of electricity producing frequent, costly repairs and high energy bills.
  • Longevity of the System: Both over utilization as well as underutilization can negatively impact the performance and life of your HVAC system. An improperly sized unit will cause a heavy load on the system, which may lead to inconsistent performance within a few years of installation. Or it may completely give in, well before its typical life span of 20 years.

How to Size Your HVAC Unit

In order to determine the right size of your HVAC unit, you will need to calculate the correct BTU (British Thermal Unit). When used in relation to your AC or furnace, you need to know how many BTUs per hour the AC can remove or the furnace can add to the air. The basic rule is roughly 12,000 BTU per hour per 600 square feet of living space.

However, these are only indicative guidelines. In addition to basic square footage and BTU, your Bi-County technician considers several other aspects to determine the ideal size of the HVAC unit such as:

  • Shape and orientation of the home and sun exposure
  • Code requirements of the year that the house was built
  • Size and material of the current ductwork
  • Current insulation levels
  • Number of window, doors and potential air leakage
  • Number of lights and home appliances
  • Number and age of family members as well as lifestyle preferences
  • Efficiency rating of the new system being purchased
