WHAT DETERMINES THE PROPER UNIT SIZE FOR YOUR HOME?

“What size air conditioning unit do I need for my home?” is the most frequently asked question that our HVAC salesmen hear. As simple as the question may seem, there are many deciding factors that determines the proper size unit for each individuals home.

The process starts with a complete load calculation. The load calculation consists of simple data that determines the proper size unit for your home. Below is a list of data that we gather to decide what size unit is best for your home:

• Square footage of your home
• Volume of your home (Sq ft x ceiling height)
• Insulation in the attic and walls
• Direction your home faces (North, South, East or West)
• Total amount of glass windows and doors
• Single pane windows or double pane windows. (Double pane windows is recommended)
• Doors (Metal insulated doors recommended)
• Roof eve overhang (the more overhang = the better!)
• Air infiltration (cracks or air leaks within your home)
• Tree shading over your home
• Type of floor/slab or off ground
• Duct loss (air leakage from ductwork)

Once this information is gathered, it gets loaded into a calculation work sheet which then produces the correct tonnage of air conditioning unit that best fits your home.
