A system that has to work almost year round
In Natrona County, heat is running September through June. That is ten months, and on nights that average 14°F, a furnace is doing real work, not just taking the chill off. A new one has to be sized for that cold.
July and August bring afternoons that average 81°F, so the two months of cooling still ask something of the system. Between the furnace and the air conditioner, there is no month here when a home needs neither. Whatever gets installed has to be built to run both jobs, on the coldest nights and the hottest afternoons alike.

- When should I replace my HVAC system?
- Replace it when repairs get frequent or when the system can't keep up anymore, whichever comes first. Most furnaces and air conditioners last a couple decades, but the age on the nameplate matters less than what's actually happening in your house. If a contractor has been out more than once this year, or if your furnace is straining to hold temperature on the cold nights here, that's your sign. Homes here need heat from September through June, so waiting for a full breakdown mid-winter means waiting without heat while parts get ordered. It's worth replacing an aging system before it fails rather than after.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes. A furnace and air conditioner installed together are matched to work as one system, and pairing a new unit with an old one can mean neither runs the way it's supposed to. Homes here need heat ten months of the year and cooling for two, so the furnace does most of the work and tends to wear out first. If your air conditioner still has good years left, a contractor can size a new furnace to work with it and hold off on the AC until it's actually due.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to your ductwork, gas line or electrical, and venting. Then comes testing. The contractor checks gas pressure, airflow, refrigerant charge on an AC, and makes sure the thermostat is talking to the new equipment correctly. On a full system swap, the contractor also checks whether your ducts and vents are sized right for the new unit, since equipment installed to fit old ductwork poorly can run louder or less efficiently than it should. The job isn't done until the system is tested running, not just installed.
