What should you do when the second floor is too hot?

A trusted HVAC company advised on attic insulation to first try and resolve the heat coming through the roof

Sometimes back, I visited a friend who lived on the second floor of their apartment. While the house was charming and tastefully designed, it was not the most comfortable place to relax. The temperatures seem to be much higher than expected. Despite having the fan running and the thermostat set correctly, it appeared as though her HVAC system was broken and nothing was working. Contrary to this assumption, the unit was working perfectly. A quick check by the HVAC technician revealed that it was at its optimum. Since nothing was wrong with the unit, all that was left to do was find innovative ways to keep ourselves comfortable. One of the first things we discovered was that we needed to replace the outdoor unit. We discovered this truth after discussing it with the HVAC contractor in charge of our system. We first researched the possible causes of the excess heat since summer, and we needed a quick fix. Potential causes included the fact that the outdoor unit may require replacement, ancient and outdated. Another potential and the most probable issue was the roofing. The apartment had no protective covering, which means that all the heat was getting into the house since it was all being absorbed by the roof. With these in mind, we embarked on finding a solution. A trusted HVAC company advised on attic insulation to first try and resolve the heat coming through the roof. This was going to be one of the easiest, cheapest and quickest solutions. We settled on an insulation material that was quick to fix, and this made a massive difference as the house became cooler. Other possible solutions included changing filters, insulating windows, and changing the fan setting from auto to on.
