Nixa asks a lot of a new system, in both directions

Your new system needs to hold up on winter nights that average 26°F and summer afternoons near 87°F. That is 11 months out of the year it is running, heat from October through April and cooling from June through September. There is almost no season off.

A new furnace or air conditioner sized right for this stretch of Missouri has to handle both ends of that range, not just one. And with wind events and winter storms common enough here to cut power for close to a fifth of households in a given year, it is worth asking your contractor how the system you choose comes back on once the power does.

When should I replace my HVAC system?
Look at how the equipment has been running, not just its age. A furnace or air conditioner that needs frequent repairs, or one that runs constantly without keeping the house comfortable, is telling you it is on its way out. Homes here need heat from October through April and cooling from June through September, so the system only gets a short break in spring and fall. A contractor can look at the equipment and tell you whether another repair makes sense or whether it is time to replace it.
Should I replace my furnace and air conditioner at the same time?
If both are old and worn, yes. A furnace and air conditioner installed together are matched to work as one system, and putting a new unit next to an old one can mean the old unit fails soon after anyway. Replacing both at once also means one job instead of two later on. If one unit is clearly newer and running well, a contractor can check both and tell you whether it is worth waiting on that one.
What happens during an HVAC installation?
A contractor removes the old furnace, air conditioner, or both, and disconnects the ductwork, gas line, refrigerant lines, and electrical connections tied to them. The new equipment goes in, gets connected to the ducts and power, and the refrigerant lines are charged and sealed if an air conditioner is part of the job. Once everything is in place, the contractor tests the system, checks airflow at the vents, and confirms it cycles on and off correctly before calling the job done.
