Why Does the Room Over the Garage Feel Like a Sauna?


Have you ever gone into your walk-in closet after showering just to feel the need to shower again after exiting? Do you have a hard time keeping your room comfortable? Is this room, perhaps, over the garage? With temperatures in the triple digits, and monsoon season’s imminent arrival, it’s little wonder why.

There are several reasons why rooms directly above or adjacent the garage are SO hot in the summer. The main contributor, however, is often due to the fact that these rooms are exposed to the elements on three sides – in addition to sitting on top of a garage that is often just as hot as outside temperatures.

Other key factors for a room being consistently bombarded with heat gain include, but are not limited to, the following. Whether you’re suffering with one, or a combination of these factors, they’re all a recipe for excessive monthly energy bills and uncomfortable living conditions.

  • Missing insulation.
  • Poor air circulation.
  • Heat gain from sun struck windows.
  • Not in close proximity to the air handler.
  • Reduced capacity of the HVAC system from bad duct work.
  • Excessive heat gain from attic to first floor wall cavities.

When your home energy auditor utters the word “heat gain”, they’re more likely to be met with groans and murmurs of “Why me?”, rather than a “Heck yeah.” So how do you combat heat gain? One of the first things you should look at is your sun struck windows.

Windows are meant to allow light in – not for energy efficiency. Even triple paned glass and HD windows need added protection to offset any downsides caused by those that are in the sun’s direct path. Installing shade screens on sun struck windows is your best bet for making these rooms more comfortable.

Shade screens, also referred to as privacy screens, can drastically cut the heat gain in half before it gets the chance to hit the window. Window treatments and film don’t do nearly as a good a job. Weatherization, according to SRP, is yet another nemesis we need to combat.

Weatherization includes sealing any, and all, air leaks within your home. Working from the outside in is important if you’d like to keep your conditioned air inside your home for longer periods of time. Weatherization also includes locating and remedying areas in need of increased insulation materials.

Insulation may be low or completely missing in rooms above the garage – especially if the room is isolated from the rest of the house (often the case in additions). In terms of added comfort, it pays to have an insulation contractor come out, and assess the insulation within this area of your home.
