If your house in Upland still feels hot even with the AC running, the problem is usually your windows—not your air conditioning. Total Home Windows identifies exactly where heat is entering and provides proven solutions to stop it at the source.
Many homeowners assume their AC isn’t strong enough, but in reality, heat is constantly pushing in through inefficient windows. If your home still feels hot even with AC, your windows may be the cause.

Why Homes in Upland Get So Hot
Upland homes heat up quickly because of intense sun exposure, inland temperatures, and aging construction.
Unlike coastal areas, Upland experiences stronger, longer-lasting heat throughout the day. That heat hits your windows directly—especially west- and south-facing sides—and pushes inside.
In homes across Upland, we often see older windows that were never designed to block modern heat levels. Many homeowners don’t realize those windows are acting like heat magnets.
The Real Cause: Heat Coming Through Your Windows
Heat enters your home through glass, frames, and air leaks around your windows.
Standard or aging windows allow solar heat gain, meaning sunlight passes through the glass and turns into trapped heat inside your home. At the same time, poor seals let hot air leak in continuously.
A common issue we find is that homeowners upgrade their AC but never address the windows—so the heat never stops entering.
If you’re dealing with this, see why homes stay hot even with AC in Upland.
Why Your AC Can’t Keep Up
Your AC isn’t failing—it’s being overworked by constant heat intrusion.
When windows allow heat in all day, your AC runs longer and harder just to maintain temperature. That leads to uneven cooling, higher energy bills, and rooms that never feel comfortable.
In many Upland homes, we notice rooms facing direct sun are significantly hotter, even with the AC running full blast.
The Solution: Stop Heat at the Window Level
The only way to fix a hot house is to reduce how much heat enters through your windows.
Energy-efficient upgrades like Low-E glass, dual-pane systems, and insulated frames are designed to reflect heat away instead of letting it in.
