What a new system in Pella has to handle
Winter nights here average 17°F from December through February. Whatever you install has to carry the house through cold like that, and the heating season runs eight months, October through May. Summer asks less of it. Afternoons average 83°F over just three months, June through August. Size the system for the cold first. That's where it will be working hardest.
Most homes in this area heat with gas, and between the furnace and the air conditioner, a system here runs 11 months out of the year. Power matters too. Across Iowa, 15% of households went at least 24 hours without power in 2024, and the storm record for this area includes 20 winter storms and 79 damaging wind events over the past ten years. A new system installed here needs to be able to start back up on its own once the power does.

Iowa requires HVAC contractors to hold a state license.
Iowa licenses HVAC contractors through the Iowa Plumbing and Mechanical Systems Board. That license is on record with the state and covers the contractor, not each job, so the same license applies whether they are installing a furnace, an air conditioner or a heat pump.
For an installation like this, that license is your main protection, but it is not the only check. In most cities and counties, replacing a furnace or air conditioner needs a permit from the local building office and an inspection once the work is done.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is old enough that repairs keep coming back, or a repair costs a large share of what a new unit would, replacement makes more sense than another patch. Age matters too. A furnace or air conditioner working hard past 15 years is more likely to fail at the worst time, and here that means a stretch of winter nights averaging 17°F. If your system is short-cycling, running longer than it used to, or a contractor has told you the heat exchanger or compressor is failing, that is your answer already.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to replace them together. A furnace and air conditioner installed at the same time are matched to work as a system, and pairing a new unit with one that is already worn down often means the older one drags down performance or fails soon after anyway. Homes here need heat or cooling 11 months of the year, so both sides of the system get heavy use. If only one has actually failed and the other is still in good shape, a contractor can tell you whether it is worth replacing now or waiting.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner and puts in the new equipment, connecting it to your ductwork, gas line or electrical circuit, and the condensate drain. They will also check that your ducts are sized right for the new unit, since a system that does not match the ductwork will not heat or cool evenly. In most places here, this job needs a permit from the local building office, and the work gets inspected once it is done. Expect the contractor to test the system before they leave, checking things like airflow, refrigerant charge, and that the thermostat is talking to the new equipment correctly.
