How much could window tint cut your summer cooling costs?
Answer a few quick questions about your windows and AC. We'll estimate your potential monthly and yearly cooling savings — based on typical heat-reduction ranges for professionally installed window film.
Where's the property?
Your local climate and typical utility rates shape the estimate.
Please enter a ZIP code or city so we can factor in your climate.
What kind of property is it?
Homes and businesses heat up — and cool down — differently.
What's your electric bill in a typical summer month?
Your best guess is fine — June through September.
How many windows get direct sun?
Count the ones the sun actually hits during the day — those are the ones doing the damage.
Roughly how much of that glass gets sunny?
A typical window is about 12 sq ft. A sliding glass door is about 40 sq ft.
Which way do your hottest windows face?
Tap all that apply. Not sure? Afternoon sun usually means west.
How strong is the direct sun on those windows?
What kind of glass do you have?
"Not sure" is a perfectly good answer — most people aren't.
What's on those windows right now?
What's bothering you most?
Tap all that apply.
How does your AC handle the summer heat?
Roughly how old is your AC system?
Older systems work harder against heat coming through glass — it affects the estimate.

🧮 How we calculate this
No black box — here's the exact recipe, using your answers:
- Start with your summer bill. We use the midpoint of the range you picked.
- Take the cooling share. In a hot climate like ours, roughly half of a summer electric bill is air conditioning.
- Isolate the sun's share. Sunlight through glass drives a chunk of that cooling load — we assume 15–45% depending on how much sunny glass you have.
- Adjust for your situation. Window direction, sun strength, glass type, existing coverings, and how hard your AC works each nudge the number up or down.
- Apply the film. Professionally installed ceramic film typically rejects a large share of solar heat. We model 40–65% of that window-driven load going away — that's why you see a range, not one number.
- Stretch it over the season. Yearly figures assume 5–7 months of meaningful cooling, which fits the Gulf Coast.
Disclaimer: These are planning estimates based on typical heat-reduction ranges, not measurements of your home and not a guarantee. Actual results vary with utility rates, weather, glass type and condition, sun exposure, HVAC efficiency, insulation, thermostat habits, and the specific film selected.
