Indoor Air Quality

As homes are being built smaller to conserve energy, indoor contaminants lead to indoor air quality issues. Also, residents tend to open their windows less often nowadays due to energy costs, drafts, noise and security issues.

We offer products and services to make the air you breathe in your home safe and clean. Also installing IAQ products will help your heating and cooling equipment run more efficiently and last longer. We have many different levels of filtration and UV air purifiers depending on what you or your home needs.

Heat Loads

Your building or room acquires heat from different sources- solar radiation, computers, lighting, copiers, machinery, etc. The sum of all these sources of heat combined is referred to as heat load.

Heat load, measured in BTU (British Thermal Units) or Kw (Kilowatts)., is the amount of heat needed to be removed within a certain period of time.

For your air conditioning unit to cool your building, the output should be higher than the heat load. Hence, it is important to perform a heat load calculation before purchasing an AC unit.

Environmental Heating & Cooling offers heat load calculations with an estimate to ensure proper duct sizing, proper unit sizing, proper indoor air quality, and reduced initial unit cost.
