My second floor is too hot. How can I fix it?

Is your home comfortable until you walk upstairs? Suddenly, your air temperature transforms to that of your gym’s sauna. In the understatement of the year… your second floor is hot.

Before you commit to hibernating in the basement until Halloween, use this list to pinpoint what may be causing your second-floor heat wave.

Ducts: ductwork slips over time, allowing energy loss and cool air to escape before reaching the second floor. Feel the air vents when the AC is kicked on. Is the air warm or cool when it comes out? Also, do you have a dust problem? Either one could name your ductwork as the culprit.

Thermostat: heat rises. So when the heat from downstairs rises to upstairs, yet your only home thermostat is on the first floor, it may register that the home is comfortable, yet it is the tropics upstairs. Ideally, have one thermostat per floor. A system with smart thermostat capabilities and zone heating is the top choice, but simply allowing your system to know the upstairs is the Sahara Desert is a good place to start.

Insulation and Air Leaks: have you checked your attic or upstairs insulation? Proper insulation creates a thermal boundary between the indoor and outdoor air. If it lacks insulation, you are letting air escape. While checking your insulation, inspect your attic for gaps and holes that allow heat to enter and cool air to escape.

Your Unit: this is the last thing you want to hear, but if your unit is 10-15 years old, it may be hanging up the towel, so to speak. If this is the case, Krantz can help you find a new unit in your budget, fitting your home’s needs.

What to do: a few tricks can make the air more comfortable in your home. Ensure you change the filters in your unit. During the heat of the day, use blinds and curtains to keep the sun out of your home. Turn off lights as much as you can to reduce creating heat. Turn your AC to “on” versus “auto.” This continuous cycling of air allows a better mix of air. Consider using zone heating and cooling to force more air upstairs to keep the second floor more comfortable. Use fans to circulate the cooler air that hangs out by the floor. 

Finally, if nothing has helped, give Krantz a call. Our technicians are trained to help you create the perfect environment for your family… on all floors of your home.
