Cold Blow & Uneven Temps - Xenia, Ohio
Duct Sealing Key To Preventing Cold Blow & Discomfort With Heat Pumps. How Aeroseal’s Air Sealing Of Duct Work Prevents One Of The Most Common Heat Pump Complaints.
AVG Register Temp = 26°C
CFM Loss = 245 (20%)
After Aeroseal
AVG Register Temp = 31°C
CFM Loss = 27 (2%)
Results
An improvement of 5°C in Average Register Temp @ Max Heating. An 88% decrease in CFM of Air Flow Loss. Completed in less than a day and without demolition or changes to existing system.

Before Aeroseal
Maintaining a constant temperature in the home during the colder months has been an ongoing struggle for this Xenia, Ohio family since moving in back in 2018. So much a struggle that they installed a wood-burning stove to supplement their heat pump system during the coldest months of the year.
​
When the thermostat would be set at 21°C, register air temperatures would range anywhere from 32°C to as low as 17°C at the far ends of the house, meaning the heat pumps were actually cooling certain rooms of the home. This problem could be caused by a variety of things, but mainly due to leaky ducts. The conditioned air moving through the ductwork is lost through poor connections and by the time it reaches the register, the conditioned air is lost.​​
"Knowing that heat pumps don’t really provide as much warm air (as oil furnaces), when we bought the house we were concerned about how high our energy bills could be in the winter due to having a ducted electric heat pump system. Not only that, the furthest rooms from the furnace – which happen to be the family room and living room where we spend a majority of our time together as a family – were always cold because of the small amount of airflow coming out of the registers. After Aeroseal, not only can you feel a difference in the amount of air coming out of the registers, but those cold rooms are now more comfortable, not to mention the furnace is kicking off a lot sooner than it was before having Aeroseal work done, which we’ll hopefully see the monetary impact of that on our future energy bills."

After sealing, the system leakage and register air temperatures were measured again. System leakage was cut by over 88%, from an average of 245 CFM to 27 CFM. More impressively, the average air temperature from the registers increased by 5°, completely resolving the cold air coming from the farthest registers. This non-destructive process was able to eliminate the cold air coming from the registers and reduced leakage to only 2% without having to redo the ductwork or changing out the heat pumps.​​

Results
In less than a day and without demolition, Aeroseal was able to seal the duct system and increase overall home comfort levels.

Aerosealing is the most affordable, non-invasive and effective way to reduce leaks in your homes ductwork. The average Nova Scotian home experiences between 30 - 40% leakage on their heating and ventilation supply system. Leaky furnace, heat pump or air exchange ductwork allows clean, heated and cooled air to escape before reaching your rooms which can cause:​
-
Poor Indoor Air Quality (Dusty, Stuffy & Uncomfortable Rooms)
-
Uncontrollable Humidity Problems (Moist Walls & Windows)
-
Mold Growth Inside Ducts and Unconditioned Spaces.
-
High Energy & Heating Bills (Increased Energy Consumption)
Aerosealing solves these problems by effectively sealing your ductwork from the inside and reducing leakage to minimal levels (Under 5% Total Leakage On Average).
