Explanation of SEER

When one is in the market for energy efficiency, finding effective and efficient appliances for cooling homes has the potential to save a lot of money. SEER ratings help to figure out which cooling systems are the most efficient.

What does SEER stand for?

The Seasonal Energy Efficiency Ratio rating system was developed as a performance standard by the combined efforts between the U.S. government and equipment manufacturers with the intent to create a rating system that is easily understood by the public.

What Do The Numbers Mean?

The number that is associated with a SEER rating measures the British thermal units per hour of cooling or heating, per watt of electricity. The higher the number, the more efficiently a product will produce cool air compared to a product with a lower number.

How Does It Work?

The higher the SEER rating, the more energy efficient an appliance is. In early 1990s, many cooling units carried … Read Full Post »

WORKING WITH A CONTRACTOR

Many homeowners choose to hire a professional contractor for duct improvement projects. Most heating and cooling equipment contractors also repair ductwork.

Look for a contractor that will:

  • Inspect the whole duct system, including the attic, crawlspace, garage and basement as needed.
  • Evaluate the system’s supply and return air balance. Many systems have air return ducts that are too small.
  • Repair damaged and disconnected ducts and straighten out flexible ducts that are tangled or crushed.
  • Seal all leaks and connections with mastic, metal tape, or an aerosol-based sealant.
  • Seal all registers and grills tightly to the ducts.
  • Insulate ducts in unconditioned areas with duct insulation that carries an R-value of 6 or higher.
  • Include a new filter as part of any duct system improvement.
  • Evaluate air flow after repairs are completed.
  • Ensure there is no backdrafting of gas or oil-burning appliances, and conduct a combustion safety test after ducts are sealed.
