A few weeks ago, we looked at a common problem homes have with central air conditioning: uneven cooling, with some rooms much warmer than others when the AC is running.
Today, we’re going to look at the most common cause of uneven cooling for homes. In two-story homes, often the upper floor is hotter than the lower floor. This is normal when there’s no central cooling or heating system running because heat naturally rises. However, a well-designed and installed HVAC system can overcome this. If you’ve discovered during this summer that the upper floor of your house isn’t getting the same level of comfort as the lower, there are some potential solutions.
August is often the hottest, most grueling month of the summer—and it’s a time when many air conditioning systems will start to experience malfunctions because of all the stress that’s been put on them. This is a good time to go over a list of the most common AC problems that can crop up, because this is when you’re most likely to run into one of them and have your comfort put in jeopardy!
You may already be looking ahead to your calendar toward the end of June and the official first day of summer. If you are, make sure that when you think of the coming summer you also think about handling the summer heat with an air conditioner in the best shape possible.

If you have some knowledge of how the modern air conditioner works, you may know it’s a refrigerant-based system, working in a similar fashion to a refrigerator. To providing cooling, both systems use chemical refrigerant to absorb heat from inside and move the heat to the outside air. This is why the condenser unit outside your house blows out heated air when the AC is working.
