Pittsburgh Air Conditioning Sizing by the Pros at South Hills Electric Heating Cooling

American Standard Air ConditioningAir conditioning efficiency for your home depends on a number of technical factors. We have had an unusually hot summer so far and many AC systems are showing their weaknesses because of this. Improper sizing can cause your air conditioning unit/s to under-perform when you need them most; costing you money and not cooling your home to your liking. The wrong size AC won’t be able to cool your living space properly and will cause you to be less comfortable. Efficiency is the key to minimizing your cooling bills and giving you the comfort you deserve.

More is not necessarily better when it comes to sizing air conditioning systems. Our technicians are trained to assess each installation individually. Over sizing your home air conditioning equipment can cause your cooling equipment to short cycle (to turn on and off frequently) which can shorten the life of your air conditioning equipment. Improper Return air on upper floors causes positive pressure holding cold air down to lower floors of your home making even properly sized equipment appear to function incorrectly.

Professional load calculations are computed and are designed to find the right size AC unit for your home’s needs. A good rule of thumb is to have about 1 ton per 500 – 700  square feet of living space that you plan to cool. Extreme conditions however cause this simple rule to need enhancement.

Why a Matched Heating and Air Conditioning System?

Most homeowners consider the components that make up their heating and cooling system to be separate units. But these components are actually integrated, coordinated pieces that are designed to work together in what is called a “matched system.” Matched systems are quieter, more reliable, and more efficient, longer lasting, thus making the most of your investment.

Factors to Consider When Sizing AC Equipment:

  • Rooms below grade are not calculated in the square footage requirements mentioned above
  • Vaulted Ceilings affect sizing tables
  • Proper Return Air requirements must be met to support your air conditioning system
  • Proper insulation in attic and walls
  • Ductwork layout and sizing
  • Square footage of windows and doors
  • Matched System components

Questions affecting sizing of Air Conditioning equipment:

  • Do High Low Returns for air flow exist?
  • Is there leakage on the return (intake) side ducts or supply ductwork?
  • Are Registers blocked or restricted?
  • Is your duct work insulated?
  • Are my components designed to work together to achieve the best efficiency?

What can I do to maximize my AC efficiency?

  • Insulate duct work from leakage with aluminum tape
  • Wrap duct work to prevent adverse climatic conditions from stealing your cold air before it’s delivered
  • Have your HVAC technician properly maintain your Heating and cooling system
  • Match your requirements to your equipment by properly sizing, maintaining, and servicing your equipment
  • Make sure your refrigerant charge is right. Overcharged systems can perform worse than undercharged systems
  • Use a programmable thermostat
