The duct systems in Mt. Prospect are leaky in both new and old homes.  Even homes under construction in the City of Mt. Prospect today, are still not required to have duct leakage testing performed on the duct systems regardless if they are inside the house or in the attic.  Priority Energy has been testing duct leakage for years across Illinois.  Cities that require duct leakage testing on ductwork outside the space (think the attic or crawlspaces) will typically leak 100-150 CFM25 (normal operating conditions/pressures) on average.  In the city of Chicago, because no systems are required to be tested, we've found the majority of systems will typically leak 400+ CFM25 on average.  

You may ask yourself, is this significant; the simple answer is yes.  Here's why; the average size air conditioner we see in single family homes in the city of Mt. Prospect is between 2 and 3 tons of cooling.  Air conditioners in our area should be set to 350 CFM/ton.  This means we're losing between 30 & 50% of our cooling capacity into floor & wall cavities or straigt to the outside.  

Next time you experience rooms that aren't cooling, excessive dust in the house, or trouble meeting and maintaing temperatures in your home; you might ask yourself if your duct work could be the issue.  When we Aeroseal duct systems in Mt. Prospect, we typically bring the total leakage to 20 CFM25 or less (we're virtually eliminating duct leakage), and the flows out each registers typically doubles or more!

Priority Energy had been doing Aeroseal longer than anyone else in Illinois, we have sealed more systems, and understand the process better than anyone else in the industry.  Call today for your quote.

  • I just wanted to send this message to all you and say GREAT JOB!  We had a rough inspection today and passed for the Woodward Ave. house. The inspector told us "if every house I inspected looked like this one I would be out a job".

  • We were so impressed with the amount of information the Priority Energy technicians gave us during our ENERGY AUDIT.  If you are buying a house, I would strongly recommend having them do an energy audit on it, in addition to your usual home inspection.

  • Thanks for a super intelligent and deep seminar expertly handled by a staff which was a pleasure to be around. Lunch was superbly and subtly handled.
