During the summer, the upper-story rooms are likely to be much warmer than the main areas of the apartment if you live in a several-story house! Changing the temperature control can cause an imbalance that results in the lower levels becoming much too cold and resulting in higher energy bills.
- A warm roof, warm air, or leaky ductwork can cause overheated upper floors, but the warm air rises, while the cool air settles at the bottom.
A home with many stories will have adequate cooling on the ground level, while heat will gather in the rooms up above. The roof can absorb radiant heat from the sunlight and radiate that heat into the rooms closest to the attic! For the cool air to reach the upper floors of the house, it must travel through longer sections of ductwork. This can make cooling these rooms even more taxing if there are leaks in the ductwork. There is no need to replace the entire A/C component in order to achieve a balanced cooling in your home, instead, you just need to replace the A/C coil. There is nothing more you need to do however adjust the dampers in each room by opening the basement and ground floor registers a bit less, and as you go up, opening them up a bit more, but making sure the air filter is clean and replacing it if needed can also help ensure common airflow… Radiant heat can be reduced by installing enough insulation on the roof as well. The roof deck or the roof floor can be installed with insulation, depending on the whole roofing style. Adding mechanical ventilation to the roof can boost attic insulation. Finally, if there are complications with the heating, ventilation, and A/C method itself, such as low air conditioner output or leaks in the ductwork, you must have it fixed by a professional heating, ventilation, and A/C specialist.
