What a Waterloo winter asks of a new furnace
Your furnace has to carry the house from October through May here, eight months of the year. Winter nights average 13°F, and on the coldest ones the burner is running most of the night to keep up. Most homes in the area heat with gas.
A new gas furnace installed today has to meet the federal minimum of 80 percent AFUE. That is the floor, not a target, and it matters most on the nights the house needs heat for hours at a stretch without a break.

Iowa requires HVAC contractors to hold a state license.
Iowa licenses HVAC contractors through the Iowa Plumbing and Mechanical Systems Board. The license is issued to the contractor, not the job, so it stays tied to their name and record no matter how many furnaces they install.
On a furnace installation, the gas connection is the part that has to be right, since a bad one is what makes the job dangerous. In most cities and counties, this work also needs a permit from the local building office and an inspection once it's done, which checks that connection separately from the contractor's license. In Black Hawk County, 63.4% of homes heat with gas, so that inspection is doing real work here.

- What size furnace does my house need?
- The right size depends on your home's square footage, ceiling height, insulation, window count, and layout, so there's no single number that fits every house. A contractor works this out with a load calculation, not a guess based on your old unit's size. Putting in a furnace that's too big or too small for the house wastes fuel and wears out faster, so this step matters more than picking a brand.
- How do I know it's time to replace my furnace?
- If your furnace is breaking down more than once a season, or a repair is going to cost close to what a new one would, replacement usually makes more sense. Watch for uneven heat between rooms, a furnace that runs longer to reach the same temperature, or a rise in gas bills that isn't explained by colder weather. Age matters too. Since homes here need heat from October through May, a furnace nearing the end of its life is more exposed here than in places with a shorter heating season.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you're paying to heat it now. Any non-weatherized gas furnace made since November 2015 already has to hit at least 80 percent AFUE, so the real comparison is between that baseline and a high-efficiency model rated well above it. With winter nights here averaging 13°F and heat needed eight months a year, a furnace here runs a lot more than one in a milder climate, so efficiency gains add up faster. A contractor can walk through the actual models and what each one would mean for your house.
