Selecting The Correct Sized HVAC System For Your Business

Providing a comfortable environment that is properly climate controlled is part of the cost of owning a business. The heating, cooling and ventilation of your business can attribute up to 40% of your energy usage, so choosing the right system is important. To make sure you are not spending more than you need to, both for the original installation and on monthly energy bills, selecting the correct size HVAC system is crucial.

Evaluating Your Load

Before purchasing a new HVAC system the first step is to know exactly what load you currently need and use to cool and heat your facility. There is several factors that affect how much energy is being used to either cool or heat a building, many of them not related to the HVAC system at. Some energy conserving techniques to consider that can reduce your loads are:

  • Better insulation. If you are losing heat through poorly insulated windows or leakage in your outer structure, getting new windows or adding tighter insulation can reduce your heating needs. The same will apply to keeping the building cool.
     
  • Lighting and equipment. Computers, lights and other equipment can contribute to heating the facility, which can cost you more if cooling is your primary concern. Energy efficient equipment and lighting can reduce the heat produced.
     
  • Sunlight factor. Sunlight can help or hinder your energy efficiency. To reduce cooling cost, reduce sunlight heat with tinted windows or shades, while using the sun to add warmth can reduce heating costs.

By using techniques to reduce your load before you buy, you can then request an evaluation of your load use after the improvements. The smaller the load need, the smaller size unit you will need, saving you money on the purchase, installation, and commercial HVAC maintenance in addition to your ongoing energy costs.
