Estimate Your Energy Savings in the Las Vegas Heat
Las Vegas runs air conditioning harder than almost anywhere in the country. Tell us about your home and current system and we'll estimate what a high-efficiency upgrade plus sealed ductwork could save you every year — in dollars, kilowatt-hours, and carbon.
Your Home & System
Estimates use Las Vegas climate cooling/heating loads (~2,200 cooling hours, ~600 heating hours), NV Energy residential rates, SW Gas therm pricing, and standard SEER/AFUE efficiency ratings. Actual savings vary with home insulation, occupancy, and equipment condition.
A high-efficiency 18 SEER system removes the same heat using far fewer watts during Las Vegas's long 110°+ cooling season.
Desert nights drop into the 30s. A 97% AFUE furnace keeps more of the gas you pay for as heat inside your home instead of up the flue.
Sealing your ducts could add $213 more in savings
Leaky duct joints waste 20–30% of conditioned air. Our fan motor & duct repair service seals and balances airflow so every room reaches temperature.
Want a real efficiency assessment of your home?
A certified Oui Air technician measures your actual load, duct leakage, and system performance — then gives you honest payback math.
