Did you know that outdoor temperatures can have a direct impact on the comfort level inside your house, but do know what climate zone you live in?

Probably not but where you live can dictate the type of HVAC system you should have in your house, as well as make a big difference on your energy bills.

The National Oceanic and Atmospheric Administration (NOAA) has determined there are five climate zones in the United States. They range from colder to warmer. Each zone contains “cooling degree days” and “heating degree days.” Zones with more heating degree days tend to be colder, while those with more cooling degree days are warmer. As a point of reference, Raleigh is located in climate zone 4, which has been recorded as having fewer than 4,000 heating degree days per year. Raleigh also has fewer than 2,000 cooling days per year.

Why is this important?

Warmer climates generally require larger HVAC systems. Raleigh area residents may want to consider having an HVAC professional take a look at their current system to ensure appropriate for their house and running optimally.

Other things to consider:
  • Make sure your system has a high Seasonal Energy Efficiency Ratio (SEER) rating
  • For maximum efficiency, set the thermostat to an ideal temperature and leave it there
  • Always have your AC checked every spring to make sure operating efficiently

Heating and cooling zones play an important role in controlling the temperature in a home. Having the best possible system for your climate zone can help keep temperatures comfortable and energy bills manageable.
