Butte Housing Stock
Census figures put the median build year in Butte at 1956, so a typical house here has about 70 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. About 11,000 households here own their home, 70.3% of the occupied total. With a median household income of $57,633 and a median home value of $225,100, local labor rates come out below the national middle in our model.
Silver Bow County had 1 day with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. In Butte, 19.1% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

Montana Licensing and Efficiency Rules
Montana falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Montana the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask what the emergency fee is before the truck is sent.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Maintenance plans often put members first in line for emergency calls.
