Eleven months of the year, your system is working
Michigan City asks a lot of a heating and cooling system. Winter nights average 20°F from December through February, and homes here need heat from October through May, eight months of the year. Add the three months of summer cooling, when afternoons average 81°F, and a system is running nearly year round.
Most homes here heat with gas, and whatever you install has to handle both ends of that range, the cold nights and the warm afternoons. Power outages are common enough in Indiana that it's worth asking a contractor how a new system starts back up when the power comes on, especially heading into a winter storm.

In Indiana, HVAC licensing for homes is left to the counties and cities.
LaPorte County sets its own rule for who can do this work, since Indiana leaves HVAC licensing to cities and counties rather than handling it at the state level. That means there is no state record of testing behind a contractor here, no license number tied to a state board. Whatever protection exists comes from the county or city itself, and it can look different depending on which part of LaPorte County the house is in.
For an installation like this, most cities and counties require a permit before the work starts and an inspection once it is done. The permit puts the job on file with the local building office. The inspection is someone from that office looking at the finished system, including the gas connection if the system runs on gas, since a bad connection there is the dangerous part of the job. That inspection checks the work itself, after the fact. It is not a license, and it does not test the contractor ahead of time.

- When should I replace my HVAC system?
- Replace it when repairs start piling up or the system can't keep up anymore, whichever comes first. Homes here need heat or cooling 11 months out of the year, so a furnace or AC in this area logs a lot of hours and wears accordingly. If you're calling for repairs most seasons, or a repair quote is getting close to what a new system runs, replacement is usually the better move. Rising energy bills with no other explanation are another sign the equipment is losing efficiency.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes. A furnace and AC installed together are matched to work as one system, and pairing new equipment with an old unit can mean it never runs at its rated efficiency. It also means you're not paying for a second installation visit later when the older unit fails on its own. That said, if one unit is still fairly new and working fine, there's no reason to replace it just because the other one needs to come out.
- What happens during an HVAC installation?
- A contractor starts by sizing the new equipment to the house, since a furnace or AC that's too big or too small won't heat or cool evenly. The old furnace, coil, or condenser gets disconnected and removed, and the new equipment is set in place and connected to the ductwork, gas line, refrigerant lines, and electrical. Once it's hooked up, the contractor tests it, checks refrigerant charge or gas pressure, and confirms the thermostat and airflow are working the way they should. The exact steps and timeline depend on what's being replaced and the layout of the house, so a contractor can walk through specifics for your situation.
