A furnace built for seven months of work

Prescott Valley needs heat from October through April, seven months of the year. Winter nights average 31°F, so a new furnace has to hold up to a long season of nightly cycles, not just the occasional cold snap.

Any furnace installed new has to meet the federal minimum of 80 percent AFUE, and it's worth confirming that whatever goes into your home meets or beats that number. Yavapai County has also logged 44 winter storms and 94 damaging wind events over the past ten years, the kind of weather that can knock out power. Most furnaces need electricity to run the blower and controls, so when the power drops, so does your heat, until it comes back on.

What size furnace does my house need?
It depends on your square footage, your ceiling height, how much insulation you have, and how many windows face north. A contractor works this out with a load calculation, not a chart based on home size alone. Too big and the furnace short cycles, heating the air fast then shutting off before the house evens out. Too small and it runs constantly during your coldest nights and still falls behind. Since homes here need heat from October through April, getting this number right matters for most of the year, not just a few cold snaps.
How do I know it's time to replace my furnace?
An aging furnace that needs more repairs each winter is usually the first sign. If you have already called someone out more than once this season, that is worth paying attention to. Watch for uneven heat between rooms, a burner flame that looks yellow instead of blue, or a furnace that takes longer to reach the temperature it used to hit quickly. Any one of these on its own is worth a look. Together, they usually mean the furnace is on its way out.
Is a high-efficiency furnace worth it?
It depends on how long you plan to stay in the house and what your furnace is doing now. Furnaces made since November 2015 are required to hit at least 80 percent AFUE, so even a standard replacement today burns less gas than an older unit. A high-efficiency model goes further, wasting less heat out the vent, and with close to half of homes here heating with gas, that difference shows up over years of winter use that run October through April. A contractor can walk through the options for your specific furnace and tell you what fits the house.
