HVAC Tools Built for New Orleans Homes
Size a system, estimate your cooling bill, check a payback, triage a symptom, score your storm readiness, and see what today's weather means for your home. Every tool gives honest ranges — the accurate answer always comes from a free, in-home visit by our techs.
AC & Heat-Pump Sizing
What Size AC Do I Need?
Get a quick, honest size range for a New Orleans-area home. This is a ballpark to set expectations — the accurate method is a Manual J load calculation from our techs.
On the Gulf Coast, bigger isn't better. An oversized system short-cycles and never runs long enough to pull humidity out — leaving your home cold but clammy.

Cooling Cost Calculator
What Does It Cost to Cool My Home?
Estimate your monthly and yearly cooling cost from your system's size, efficiency, and your real electricity rate. We show a range, because the weather and your thermostat move the number every day.
Tip: divide your Entergy bill total by the kWh used for your real rate.
Greater New Orleans typically runs a long cooling season — 6 to 8 heavy months is common.
$71–$96/ month
About $496–$671 per cooling season · ~694 kWh/month
This is an estimate, not a bill. A clean, well-maintained, right-sized system runs the fewest hours — that's the cheapest way to cool a New Orleans home.
Upgrade Payback
Will a New, Efficient System Pay for Itself?
Compare your current system's efficiency to a new one and see the estimated annual savings and payback period. Then see why financing can make the math work from month one.

A placeholder — your real price depends on the equipment, ductwork, and your home. We give you the exact number in a free estimate.
12.4–16.7years
Est. $478–$647 saved per year on cooling
With financing through Wisetack, Goodleap, FTL, the monthly payment can be less than what you save — so an upgrade can pay you back long before the headline payback year.
HVAC Symptom Checker
What's Wrong With My AC?
Two quick questions for the most likely causes and how urgent it is. These are possibilities to help you understand what you're seeing — not a diagnosis. Only an on-site check can confirm the real cause.

Storm-Season Readiness
Is Your HVAC Ready for Storm Season?
A quick yes/no check built for the Greater New Orleans hurricane season. Your score updates as you answer — then get a plan to close any gaps before the next storm.
Do you have surge protection on the AC (whole-home or a unit surge protector)?
Is your outdoor condenser elevated on a raised pad or stand?
Has the system had a professional tune-up in the last 12 months?
Is the outdoor unit secured/strapped against high wind and flying debris?
Do you know how to safely shut the system off before a storm?
Are you generator-ready (or do you know your system's startup needs after an outage)?
Do you have a plan to have the system inspected before restarting it after a storm?
Your readiness score appears here
Answer the checklist and we'll show your score and the gaps to close.

Tool FAQs
How to Read These Tools
Straight answers on what these calculators can and can't tell you — and how to get the accurate version.
How accurate is the AC sizing estimator?
It gives a rough starting range based on square footage and a couple of factors — useful for ballparking, not for buying equipment. The accurate method is a Manual J load calculation, where our technicians measure your home's windows, insulation, ductwork, air infiltration, and orientation. Right-sizing matters even more on the Gulf Coast: an oversized AC short-cycles and never runs long enough to pull humidity out of the air, leaving your home cold but clammy.
Where do I find my system's tonnage and SEER for the calculators?
Tonnage and the SEER (or SEER2) rating are printed on the data plate on your outdoor condenser, and often on the original paperwork. If you can't find them, our team can identify them on-site. The cost and payback numbers these tools produce are estimates — your real usage depends on your thermostat habits, your home, and the weather.
What electricity rate should I enter for the cost calculator?
Use the all-in rate in cents per kilowatt-hour (¢/kWh) from your most recent Entergy bill — divide your total bill by the kilowatt-hours used. We pre-fill a reasonable New Orleans-area default, but your actual rate, fees, and seasonal pricing will differ, so editing it gives you a more honest estimate.
Can these tools diagnose what's wrong with my AC?
No. The symptom checker lists likely possibilities to help you understand what you're seeing — it is not a diagnosis. Many HVAC symptoms share several causes, and only an on-site inspection can confirm the real one. If you have no cooling in the heat, smell burning, or see ice on the unit, call us right away at (504) 915-9747.
Why does humidity matter so much for HVAC in New Orleans?
Our hot, humid Gulf Coast climate means your system isn't just cooling air — it's removing a large amount of moisture. High indoor humidity feels sticky, encourages mold and dust mites, and makes you crank the thermostat lower than you need to. Properly sized equipment, good airflow, and indoor-air-quality solutions like dehumidification keep your home comfortable without overworking the AC.
Do you offer financing for a new system?
Yes. We offer flexible financing through Wisetack, Goodleap, FTL, including low- and zero-down options with approved credit. For many upgrades the monthly payment is less than the energy and repair savings, so a more efficient system can be cash-flow positive from day one.
How do I get an accurate, personalized recommendation?
