A furnace here never really gets a break
Winter nights in Anaconda-Deer Lodge County average 13°F, and homes here need heat all 12 months of the year. There is no real off season where a furnace sits idle for months at a time. It cycles on and off through summer nights too, and that adds up to a lot more starts and stops over a year than a furnace in a milder place ever sees.
Most homes here heat with gas. A new gas furnace installed today has to meet the federal minimum of 80 percent AFUE, so a chunk of what it burns has to go into heat for the house rather than out the flue. Worth asking about a model that clears that bar by a wide margin, since this one will be working most months of the year for as long as it's in the house.

Montana requires HVAC contractors to hold a state license.
The license is held by the contractor's business, not issued job by job. It comes through the state's Department of Labor and Industry. Montana carves out an exception for small work. Anything under $2,500 doesn't require a licensed contractor. A furnace installation runs well past that line, so this job falls under the licensing rule stated above.
That license tells you the contractor was tested and is on record with the state. In most cities and counties, an installation like this also needs a permit from the local building office, with an inspection once the furnace is in. Most homes in Deer Lodge County heat with gas, and a furnace installation is where that matters most.

- What size furnace does my house need?
- It depends on your home's square footage, how well it's insulated, your window count, and your ceiling height, so there's no single number that fits every house. A furnace that's too big cycles on and off too fast and never runs long enough to heat evenly. One that's too small runs constantly and still can't keep up on the coldest nights, and with winter lows here averaging 13°F, undersized is the worse mistake to make. A contractor sizes the furnace with a load calculation on your actual house, not a rule of thumb based on square feet alone.
- How do I know it's time to replace my furnace?
- Age is one sign. An older furnace works against wear that adds up over the years, and repairs start costing more as parts get harder to find. Watch for uneven heat between rooms, a furnace that cycles more than it used to, or a rise in gas use without a reason. Since homes here need heat every month of the year, a furnace that's struggling doesn't get an off season to make up for it, so a failing one shows its problems fast. If a contractor has already been out more than once this year for the same issue, that's usually the point to stop repairing and start pricing a replacement.
- Is a high-efficiency furnace worth it?
- Every non-weatherized gas furnace sold new today has to reach at least 80 percent AFUE, so the real question is whether to go higher than that baseline. A high-efficiency model wastes less gas by pulling more heat out of the exhaust before it leaves the house. With 66.3 percent of homes in Deer Lodge County heating with gas and furnaces here running nearly year round, that difference in efficiency gets used a lot more than it would somewhere with a short winter. A contractor can walk through which efficiency level makes sense for your house and your furnace's venting setup, since higher-efficiency units vent differently than standard ones.
