The size of your business HVAC system will vary depending on how much space you need to heat and cool. You may not be able to make your area pleasant with a system that is too tiny.
Extremely powerful heating and cooling systems cycle on and off too frequently, producing unnecessary wear and tear and increasing your utility bill. Additionally, your HVAC contractor should take into account other aspects that affect the heat gain or loss in your commercial space, such as the type of materials used in your construction.
