Newer homes, and newer furnaces

Sergeant Bluff has some of the newest housing around Sioux City: half its homes were built in 1996 or later, and only about a third before 1980. It also leans on natural gas more than any other town on this site, at roughly three homes in four.

A house from the late 1990s or the 2000s is now on its first or second furnace, and many of those are high-efficiency models vented through plastic pipes out the side of the house. Two things follow:

Winter shutdowns from the vent. Drifted snow over a sidewall vent, or a condensate line that froze, can stop a furnace that is otherwise fine.
First replacements coming due. Furnaces and air conditioners put in when these homes were built are reaching the age where a large repair raises the replacement question.

Air conditioners from the R-410A years

Homes built after about 2006 most likely received R-410A air conditioners. Those systems can still be repaired and recharged, but new equipment has moved to R-454B and R-32. When an older outdoor unit fails, the installer will usually quote a new coil too.

Before you call

Have the year of the furnace and AC from the labels, what the system is doing, and whether the vent pipes on the outside wall are clear of snow.

Checking a contractor in Iowa

Iowa licenses heating and cooling contractors at the state level. The Plumbing and Mechanical Systems Board, part of the Iowa Department of Inspections, Appeals, and Licensing, licenses the HVAC, refrigeration, hydronic and sheet metal trades, and requires anyone contracting for that work to hold a license and register with the state.

The City of Sioux City adds its own layer: its inspection office says HVAC contractors must be licensed by the State of Iowa, have an Iowa-licensed master of record, and carry a bond made out to the city. Licensed contractors pull trade permits for mechanical work through the city's permit center.

Ask the contractor for their Iowa license number and look it up in the state's public license search before work starts.
