You’re probably not getting that extra efficiency you paid for

Sealing your ducts is the best way to achieve maximum efficiency from your equipment.

Sealing and insulating your ducts increases system efficiency, lowers your energy bills, and can often pay for itself in energy savings. Plus, if you’re planning to install new heating and cooling equipment, a well-designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification.

Impact is up to 50% greater on AC performance if return air leakage is from a hot attic or attached garage. Impact is typically 50% to 100% greater on winter heating performance of a heat pump with electric resistance auxiliary heat.
Typical Duct Leakage

25-40% Energy Loss

“Typical duct systems lose 25-40 percent of the heating and cooling energy put out by the central furnace, heat pump or air conditioner. Duct repairs could be the most important energy improvement measure you can do.”

U.S. Department of Energy Consumer Report

“For an average home, leaky ducts can waste hundreds of dollars each year. Duct leakage also lowers the heating and cooling capacity, and can lessen equipment life.”

Thinking About Buying a New A/C or Heating System?

Don’t let your old ducts keep you from getting the high performance you are paying for!

An investment in a new high efficiency heating and cooling system should save significantly on your utility bills. However, you won’t save much if your existing ductwork is in bad shape.

Plus, if you’re planning to install new heating and cooling equipment, a well-designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification.

Here’s a short checklist of steps to take when looking into replacing your equipment:

Check Icon  Slow down and do your research

Check Icon  Find a contractor who can follow best industry practices when selecting a new system

Check Icon  Get a comprehensive home & duct performance assessment

Check Icon  Have test ran to measure air duct leakage, airflow and static pressure

Buying new high efficiency heating and cooling equipment, and then hooking it up to the typical inefficient duct system, is like buying a super-fuel efficient hybrid car and then driving it with a leak in the gas tank.

Bigger is Not Always Better

Does your current system seem to run non-stop, or do you have rooms that are too hot or too cold? If you were unhappy with your old unit, don’t just assume you need bigger equipment. The real cause may be a bad duct system. It’s rare to find a unit that actually is undersized. More often, the real problem is a weak duct system, air leaks, missing insulation, or inadequate maintenance.

An oversized heating & cooling system leads to:

  • Higher Utility Bills
  • More Breakdowns & Repair Bills
  • Uneven Temperatures
  • Uncomfortable Summertime Humidity
  • Increased Noise
  • Greater Duct Leakage
  • Increased Mold, Dust Mites and Allergies

Aeroseal Results

Homeowner Combines Duct Sealing With New HVAC

This Cincinnati, OH homeowner had an annual ritual of placing window air conditioners in her upstairs bedrooms every summer. She then said enough is enough. After looking into replacing her heating and cooling equipment, her HVAC contractor told her that new high-efficiency equipment would not deliver the comfort and efficiency she was desiring until her very leaky ducts were sealed.

That’s when she was introduced to Aeroseal and learned how our new approach to duct sealing seals all the leaks of her ductwork to efficiently deliver conditioned air where it’s intended to go. Click the link below to see the results and learn how we helped fix her home!
