Sizing Calculators for Utah Homes

Three free, Utah-specific calculators that give you an honest answer before you talk to any contractor. Built by a licensed Utah HVAC, plumbing & electrical contractor — no email gate, no upsell, just math.

HVAC Sizing Calculator

AC tonnage + furnace BTU for your Utah home

•Accounts for Utah elevation (4,500–7,000 ft) where standard calculators fail
•Adjusts for insulation, window area, sun exposure
•Gives you the AC tons and furnace BTU input you actually need — not a contractor's guess

Water Heater Sizing

Tank gallons or tankless GPM for your household

•Right-sizes by simultaneous-use scenarios (shower + dishwasher + laundry)
•Accounts for Utah's cold incoming groundwater (~40°F) on tankless sizing
•Tells you if a tankless or a tank water heater fits your demand better

Electrical Panel Amperage

100A vs 150A vs 200A vs 320A service

•Adds up your real loads — EV charger, heat pump, AC, water heater, stove, etc.
•Tells you whether your existing panel can fit a new load, or if an upgrade is needed
•Follows NEC Article 220 load-calculation methodology

Why our calculators give different answers

Generic online calculators don't know Utah. They use sea-level performance ratings — yet a furnace at 5,000 ft elevation loses about 20% of its rated output, and an AC condenser at 7,000 ft loses about 28%. Our calculators bake in elevation derate, Utah's typical dry-bulb design temps, hard-water considerations for water heaters, and NEC 220.83 demand factors for electrical loads.
