Why Upstairs Rooms Stay Hot During Summer

If you recall elementary school science classes, you know that hot air rises because faster-moving atoms make the air lighter and less dense than the cooler air around it. However, you don’t need a science lesson to know that the upper floors of your home are hotter than the first floor during the sweltering summer months.



Since you don’t want your upstairs bedrooms to feel like a sauna when you’re trying to sleep at night, you likely crank the AC. This can leave your downstairs frigid and send utility bills sky-high. What causes uneven cooling in Wylie, TX, and what can you do to address it so your home remains comfortable on every floor?

Inadequate Insulation

Insulation in the home works in two ways. It keeps hot exterior air out while stopping the cool air from your AC from escaping. If the insulation in your walls and attic and the insulative properties of windows and doors are inferior, heat transfer is practically a foregone conclusion.

Addressing this cause of uneven cooling in Wylie, TX, could be costly, depending on the source of the problem, but the energy savings and interior comfort you’ll enjoy afterward make it worthwhile. Start with a home energy audit to pinpoint problem areas and go from there.

Improper (or No) HVAC Zoning

Many homeowners don’t even know what HVAC zoning is, much less how it can help regulate interior temperatures. The average home features a single thermostat, typically located on the first floor. It has a sensor that tracks temperature shifts so signals can be relayed to a furnace or AC unit, telling them when to kick on.

Zoning involves adding thermostats to different areas, or zones, in the home so that each can independently signal the HVAC system to pump air to the zone in question. For example, you might have two zones in a two-story home, one on each level. This way, you can cool the upstairs without turning the first floor into an icebox.
