Central AC installed right, sized for your home

AC sizing matters more than most homeowners realize. Oversized units leave the house clammy because they cycle off before pulling humidity. Undersized units run constantly without ever getting cool. Both wear out faster than correctly sized systems.

Every install starts with a free in-home sizing assessment. We walk you through 14, 16, and 18+ SEER options, show you the break-even math, and quote in writing on the spot — no high-pressure close.

I'm glad to have found Naugle to help me with my radiator issues, as many places don't work on boiler systems. Everyone I spoke with at this company were very thoughtful and customer oriented. Thanks again!”

How much SEER do you actually need?

14 SEER is the federal minimum in Michigan. 16-18 SEER cuts cooling bills 10-25% vs. 14 SEER and is the sweet spot for most Lenawee homes — payback typically inside the equipment's life. Above 18 SEER, the payback math gets harder unless you run AC a lot, summer rates spike, or you plan to stay in the home 15+ years. We do the math with you at the estimate so you don't overspend on efficiency you won't recoup.

FAQ

Air Conditioners questions, answered

Sizing is based on square footage, insulation, window count, sun exposure, and infiltration — not a chart. Oversized ACs short-cycle, leave the house clammy, and wear out faster; undersized ACs run constantly and never cool enough. We do a full in-home sizing assessment on every install estimate so the AC is right-sized for your house.
