If you’re searching for window installation near you in Irvine, you need a contractor who can identify why your home is heating up and install the right replacement windows to fix it. In many Irvine homes, heat enters through windows first, not through the AC system, which is why proper window replacement and installation matter.
Total Home Windows (CSLB #1009760) provides professional window replacement in Irvine with vinyl retrofit, full-frame installation, and energy-efficient upgrades designed for Southern California homes.
Most homeowners call us because the house feels hot in the afternoon, certain rooms never cool down, or the AC keeps running without solving the problem. In many cases, the AC is not the root problem. Heat enters through windows, and we show homeowners exactly where that heat is coming from by measuring it inside the home.
Why This Matters in Irvine
Irvine homes deal with long sun exposure, warm inland temperatures, and rising Southern California energy costs. Even in well-kept neighborhoods, older windows can allow significant heat gain during the day, especially on west- and south-facing walls.
Many Irvine homes also have stucco exteriors and older window systems that were not built for today’s efficiency standards. When seals break down or glass performs poorly, windows become the source of the comfort problem. That is why a home can still feel hot even with the AC running.
If your home heats up during the day and stays uncomfortable into the evening, see why your house is hot even with AC in Irvine.
We do not guess. We inspect the windows, measure the heat entering through them, and give you proof inside your home so you can see whether the windows are the source.
What Type of Window Installation May Be Best
Vinyl Retrofit Window Installation
This is often the right option when the existing frame is still in good condition.
- More efficient installation process
- Lower cost than full-frame in many cases
- Good fit for many Irvine replacement projects
Full-Frame Window Installation
This is recommended when the existing frame, insulation, or surrounding condition needs to be fully addressed.
- Removes the entire old window system
- Best for damaged frames or deeper performance issues
- Allows a more complete upgrade
Energy-Efficient Glass Packages
For homes with strong sun exposure, glass performance matters as much as the frame and installation.
- Low-E coatings help reduce solar heat gain
- Dual-pane options improve indoor comfort
- Better insulation can reduce AC workload

What We Look For During an Estimate
We focus on the actual source of the problem. That means checking more than just the age of the window.
- Where heat is entering through the glass or frame
- Air leaks around the window opening
- Condition of the existing frame
- Signs of failed seals or poor past installation
- Which rooms have the highest heat load
Many homeowners assume the AC system is undersized, but often the real issue is that windows are letting too much heat into the home. Windows are the source, and until that is addressed, the house can stay uncomfortable no matter how often the AC runs.
Window Installation Cost in Irvine
Window installation cost depends on the number of windows, the size of the openings, glass upgrades, and whether the project is retrofit or full-frame.
- $800 – $1,200 per window in many standard projects
- $10,000 – $25,000+ for whole-home replacement, depending on scope
Main cost factors include:
- Window size and style
- Retrofit vs full-frame installation
- Energy-efficient glass options
- Condition of existing frames and openings
- Total number of windows being replaced

Signs You Should Replace the Windows
You should consider window installation if you are dealing with any of the following:
- Rooms that get hot every afternoon
- High cooling bills
- Uneven temperatures from one room to another
- Drafts or hot spots near windows
- Older windows that are hard to open or close
- Condensation between panes
In Irvine, these issues often get worse in homes with older glass, direct afternoon sun, and outdated window systems. Heat enters through windows, and replacing them can directly improve comfort where the problem starts.
Common Questions About Window Installation in Irvine
How long does window installation take?
Most Irvine homes can be completed in 1 to 3 days depending on the number of windows and whether the job is retrofit or full-frame.
Is window installation worth it if my AC is working?
Yes. If the home still feels hot, the AC is likely treating the symptom, not the cause. Windows may be the source of the heat entering the home.
Do new windows help lower energy bills?
Yes. Properly installed energy-efficient windows can reduce heat transfer and help lower cooling costs in Southern California.
