Buy an HVAC unit that matches the cooling and heating capacity of your home or building. Here are some tips to follow when buying a new HVAC unit:
- Make sure the size of your HVAC system is not based solely on your building or home's square footage. Structure design and efficiency also need to be evaluated.
- Replacing an old heating and cooling system requires new sizing calculations. Homes may have new additions or better insulation. Office buildings may have imposed better efficiency measures that reduce cooling needs.
- Expect the contractor to follow industry standards for calculating heating and cooling loads.
