Why Is One Room in My Arizona House Hotter Than the Others?

Almost every Arizona homeowner knows the feeling.

The thermostat says 75°, the living room feels comfortable, but you walk into a bedroom and suddenly it feels like somebody left the door open to July.

So what’s going on?

Your AC Might Not Be the Problem

When one part of your home stays noticeably hotter than another, it’s easy to blame the air conditioner. But before spending thousands of dollars replacing an AC unit, take a look above your ceiling.

Your attic insulation could be part of the problem.

Insulation that’s thin, uneven, disturbed, or missing in certain areas can allow more attic heat to transfer into the rooms below. In Arizona, where attic temperatures can become extreme during the summer, those weak spots can make a noticeable difference in comfort.

Hot Bedrooms Can Be an Insulation Warning Sign

Rooms on the sunny side of the house, additions, vaulted areas, and rooms beneath poorly insulated sections of an attic can sometimes feel warmer than the rest of the home.

Your air conditioner keeps running trying to compensate—but if heat continues entering through the ceiling, you’re fighting the problem from the wrong direction.

Look Up Before You Replace Your AC

Before assuming you need an expensive new cooling system, have your attic insulation checked.

At Active Shield Insulation, we install Johns Manville Climate Pro® blown-in fiberglass insulation and can add insulation to under-insulated areas when appropriate.

Sometimes improving the insulation above your home is one of the simplest ways to help your AC do the job it was designed to do.
