Our team recently performed an inspection for a home located in Mansfield, Texas, where a customer complained that one particular bedroom remained substantially warmer than the rest of the house, regardless of how much the air conditioning system was run. Our team was able to identify several issues that contributed to the increased temperatures, many of which are commonly in numerous homes. Read more about the results of this inspection and steps that were recommended to fix the issue on this blog.
The room, located on the southwest corner of the house on the second floor, was already in a particularly difficult spot to keep cool. It received sunlight throughout most of the day, particularly during the long and hot summer season. The roof was made of dark-colored asphalt shingles, which absorb and retain a tremendous amount of heat compared to other materials. In addition, the room had walls exposed to the attic without a proper air barrier installed over the insulation.
Our team used thermal imaging cameras on multiple points around the room to locate significant shortcomings in insulation from the attic. The attic itself would swell to temperatures ranging between 130 and 160 degrees during the sweltering heat of summer (thanks to that dark-shingled roof), and improperly installed insulation meant some of that heat was able to easily transfer to that bedroom.
One of the reasons the attic reached such sweltering temperatures was from improper ventilation. Our inspections revealed that the attic, particularly on that side of the home, had next to no way for heat to escape, resulting in scorching temperatures, which were then being pushed into the upstairs bedroom through poorly installed wall insulation.
Our professionals made four major recommendations to the homeowner to resolve their issue. First, improve the insulation around all knee walls in that bedroom. The ideal barrier would be foam board sealed with foil tape covering insulation and a radiant barrier, which is extraordinarily difficult for heat to pass through, and can help keep the climate zones separate. The Foam board and tape give the wall a continuous layer of insulation and forms an air barrier. The Radiant barrier reflects the radiant heat back into the attic.
Second, the attic ventilation needed to be rectified. No matter how good your insulation is, if your attic has sweltering, stagnant temperatures, your home will feel the effects. We recommended installing soffit vents and a solar-powered attic fan on the roof near the affected room to at least keep attic temperatures lower by continuously moving air through the attic, which will make the interior air conditioner much more effective.
Third, we recommended installing a jumper duct from the bedroom to the hallway. One of the reasons this room would get warm and stay warm was improper airflow. The carpet in the room was very thick and made it hard to close the door, which also did not allow air to escape the room when the door was closed. When a room doesn’t have good ventilation, air can stagnate and heat up, particularly when the walls are sources of immense heat like they were in this case. By improving ventilation, stagnate air can flow out of the room allowing air to circulate back through to the return of the AC system. This will allow more of the air to be conditioned to the proper temperature allowing for better overall comfort throughout the house.
And finally, we recommended sealing air conditioning ducts from the attic as much as possible. Sealing the vents at every connection point with mastic prevents further air loss by preventing heat to sneak in from the warm attic. This small step can remarkably improve the energy efficiency of an Air conditioning system and improve the equipment life span, particularly around rooms that are as warm as this bedroom.
