If your house in Santa Monica still feels hot even with the AC running, the problem is usually your windows—not your air conditioning. Total Home Windows identifies where heat is entering and provides proven window solutions that stop it at the source.
In many cases, your AC is working overtime because heat is constantly leaking in through inefficient or aging windows. That means higher energy bills, uneven temperatures, and a home that never feels comfortable.
If your home still feels hot even with AC, your windows may be the cause.
Why Your House Feels Hot Even With AC
Heat enters your home through glass, window frames, and poor seals, forcing your AC to fight a losing battle.
In Santa Monica, strong sun exposure combined with older homes creates the perfect conditions for heat gain. Many houses near the coast were built with outdated single-pane windows or early dual-pane units that no longer insulate properly.
While working with homes in Santa Monica, we often notice that rooms facing west or south get significantly hotter due to direct afternoon sun hitting untreated glass.
This means your AC isn’t the issue—it’s constantly trying to compensate for heat entering through your windows.
How Windows Let Heat In
Most unwanted indoor heat comes directly through your windows, not your walls or roof.
Standard or aging windows allow solar heat to pass through the glass and radiate into your home. Poor seals and frames also let warm air seep inside, especially during hotter parts of the day.
A common issue we find is failed seals in older dual-pane windows. Once that seal breaks, insulation drops and heat transfer increases immediately.
Many homeowners don’t realize that even clear-looking glass can act like a magnifier for heat, especially in coastal climates where sunlight reflects off surrounding surfaces.

Why This Problem Is Worse in Santa Monica
Santa Monica homes experience intense sunlight, coastal glare, and temperature fluctuations that increase window heat transfer.
Older construction is common in the area, and many homes haven’t had window upgrades in decades. Combine that with rising energy costs, and inefficient windows quickly become a major comfort and cost issue.
In homes across Santa Monica, we often see rooms that feel 10–15 degrees warmer simply because of sun-facing windows with no heat protection.
That’s why upgrading windows is often more effective than upgrading your AC system.
