Step 1 of 3: Equipment

What kind of equipment?*

Dillon asks for heat, not cooling

Winter nights here average 12°F from December through February, and your furnace or heat pump has to keep up with that every night of the season. Summer afternoons average 71°F, mild enough that most homes here get by without needing to cool at all. This is a heating system first. Whatever you install should be sized and chosen for a long, cold winter, not a hot summer that doesn't really come.

Montana sees real storms. Beaverhead County has logged 71 winter storms and 83 damaging wind events over the past ten years, and statewide, 18% of households went at least 24 hours without power in 2024. A new system should be able to come back on its own once the power does.

Montana requires HVAC contractors to hold a state license.

The license belongs to the contractor, not to any single job, so it covers every installation they do across the state. Work under $2,500 does not need a licensed contractor, but installing a heating and cooling system runs well past that figure, so the contractor doing this job needs to hold the license.

In most cities and counties, an installation like this also needs a permit from the local building office, and an inspection once the work is done. That permit is separate from the state license and comes from the local building office rather than the state.

When should I replace my HVAC system?: Once repairs on your furnace start coming back for the same problem, replacement usually makes more sense than another fix. A furnace in Dillon works hard through nights averaging 12°F from December through February, and it runs all year since homes here need heat 12 months out of 12. If the heat exchanger is cracked or the blower motor is failing, a technician will usually tell you the unit is done rather than worth patching again. Rising bills with no other explanation can also mean the system is losing efficiency as it ages.
Should I replace my furnace and air conditioner at the same time?: If your home has both and they're original to the house, replacing them together is worth asking a contractor about, since they often share the same ductwork and sometimes the same electrical circuit. Pairing the work can mean less disruption than spreading it out over separate jobs. A contractor looking at your actual setup will tell you what's there and whether replacing both makes sense for your house.
What happens during an HVAC installation?: A contractor removes the old equipment, sets the new furnace or heat pump in place, and connects it to your ductwork, gas line or electrical circuit as needed. They check the ducts for leaks or damage, since ducts sized for the old unit don't always suit the new one. Once it's running, they test it under load, check airflow at the vents, and confirm the thermostat is communicating with the system. Replacing a heating and cooling system needs a permit from the local building office and an inspection when the work is done, and the installer will usually handle scheduling that.
