Furnace Repair, Installation & Replacement

A furnace that blows lukewarm air, shuts off before the house is warm, or won’t start at all deserves a diagnosis before anyone talks about new equipment. Our furnace services begin with finding the actual fault. If the heat is out, tell us when you call and we’ll work to get a technician to you as soon as the schedule allows.

When a repair no longer makes sense, we handle furnace installation and replacement from start to finish: the load calculation, the equipment choice, the install, and the startup check. Bigfork has everything from village-center buildings to homes tucked up in the trees, and those rarely need the same furnace.

Air Conditioning Repair, Installation & Replacement

Summer is when Bigfork fills up, and an air conditioner that can’t hold the house at a comfortable temperature is hard to ignore. Our air conditioning services include AC repair, new air conditioning installation, and replacement, plus the spring tune-up that catches a weak capacitor, a dirty coil, or a low charge before the first hot weekend.

If the system is running but the house isn’t cooling, call us before it fails outright. We’d rather look at a struggling unit in June than a dead one in July.

Ductless Mini-Split Installation & Repair

A finished room over the garage, a guest cottage, a sunroom, or an addition that never got ductwork can still have real heating and cooling. Our ductless mini-split systems go in with a small hole through the wall for the line set, not a duct run through the ceiling, and we handle mini-split installation and later repairs on single-zone and multi-zone setups.

Lake places that get used in bursts are a natural fit. A mini-split heats or cools only the rooms people are in, and it responds quickly when you arrive.

Heat Pump Installation, Repair & Maintenance

A heat pump moves heat instead of making it, and one system handles both heating and cooling. Our heat pump services cover new heat pump installation, heat pump repair, and maintenance on ducted and ductless systems, including cold-climate models.

For a Montana winter, the model matters as much as the brand. We’ll go through low-temperature capacity ratings, what backup heat is paired with it, and what the system will be asked to do on the coldest nights, so you know what you’re buying before you buy it.

HVAC Maintenance Plans & Seasonal Tune-Ups

Furnace maintenance in the fall and AC maintenance in the spring are what keep a small issue from becoming an emergency call. Our maintenance agreements put furnaces, air conditioners, and heat pumps on a regular HVAC maintenance schedule, with the work done before the season that needs it.

Bigfork’s calendar is lopsided. Memorial Day weekend arrives, the Summer Playhouse season gets under way, and a lot of houses go from empty to full almost overnight. A pre-season visit means the first guests don’t find out the AC was already broken.

Whole-House Humidifier & Dehumidifier Installation

Dry winter air shows up as static, sore throats, and cracking trim. Damp summer air shows up as clammy rooms and a musty basement. Through our additional comfort services, we install whole-house humidifiers and dehumidifiers that tie into your existing system and run on their own, and we repair units that are already in place.

We check how the house actually behaves, in which rooms and which seasons, before choosing equipment.

Indoor Air Quality & Whole-House Air Purifiers

Filtration, whole-house air purifiers, and ventilation upgrades work best when they fit the system they’re attached to. We start with what you’re noticing: smoke odor after a bad wildfire stretch, a closed-up smell after the house sat empty, dust that returns a day after cleaning, or pet dander. Then we recommend equipment through our indoor air quality solutions, not a generic add-on.

Duct Sealing, Duct Repair & Custom Ductwork

Leaky, crushed, or poorly connected ducts waste heating and cooling and leave rooms uneven. We inspect duct runs, seal and repair them, and fabricate custom ductwork when a stock part won’t fit. Because our sheet metal shop is in Kalispell, one-off transitions, tight mechanical spaces, and unusual layouts get built for the job rather than forced into a standard size.

Zone Control Systems

A lower level that stays cold while the upstairs bakes, or a great room with big windows that never matches the bedrooms, is a zoning problem more often than an equipment problem. Zoning is part of the broader HVAC services we design and install, with separate dampers and thermostats working off the system you already own.

Smart & Programmable Thermostat Installation

For a house that sits closed up for weeks, a smart thermostat is the simplest piece of insurance there is: set a safe minimum temperature, check in from your phone, and raise the heat before you arrive. We install and configure smart and programmable thermostats, replace failed units, and confirm the new thermostat is communicating correctly with the furnace, AC, or heat pump.

Gas Fireplace & Patio Heater Installation

A gas fireplace gives a Bigfork living room its focal point without hauling wood, and a patio heater adds weeks of evenings on a deck when the air coming off the water turns cool. We install both, including gas piping and venting, and keep installed fireplaces running safely with cleanings and inspections.

Commercial HVAC Installation, Repair & Maintenance

A gallery, restaurant, lodge, or theater has to keep customers comfortable during the stretch of the year it earns most of its money. Our commercial HVAC work covers installation, repair, replacement, and preventive maintenance for offices, shops, and larger buildings. For a seasonal business, we plan service around the schedule it actually runs on. A system that’s checked before opening day costs far less than one that fails in the middle of it.

Why Bigfork Homeowners and Businesses Choose General Sheet Metal

General Sheet Metal has been family-owned and operated since 1942, with technicians who hold Bryant Certified Ductless Pro and NATE certifications, and we belong to the Flathead Building Association. We also fabricate our own ductwork and custom metal parts in-house. In a place where one call might be a lakeside vacation home and the next a shop on Electric Avenue, having heating, cooling, and metal fabrication under one roof keeps the job simple.

Bigfork HVAC Repair & Maintenance Questions, Answered

My furnace quit and it’s freezing out. What should I do in Bigfork?

Check that the thermostat is set to heat and that the furnace has power, then call us. Describe what you’re seeing (no heat, strange noises, a repeating start and stop) and we’ll tell you the soonest we can get a technician to the house. If you smell gas, leave the house and call your gas utility or 911 first.

My air conditioner is running but the house won’t cool down. What’s wrong?

Start with the simple checks: a clogged filter, a thermostat set incorrectly, or ice on the indoor coil or refrigerant line. If those are fine, the cause is usually a refrigerant problem, a failing component, or a system that no longer matches the house after a remodel. Turn the system off if you see ice, then call us to have it diagnosed.

Should I repair my furnace or replace it?

It comes down to the age of the furnace, how often it’s been repaired, how well it heats the house, and what the repair would cost compared with replacement. One inexpensive repair on a furnace that has otherwise been reliable is usually worth doing. Repeated repairs on an old unit that can’t keep the house comfortable point toward replacement. We’ll give you both numbers so you can decide.

Is a ductless mini-split or a heat pump better for a guest house or addition?

A ductless mini-split is a type of heat pump, so the real choice is ducted versus ductless. For a guest house, bonus room, or addition that has no ductwork, ductless is usually simpler because nothing has to be run through the walls. If the house already has ducts in good shape, a ducted heat pump or a furnace and AC pairing may make more sense. We’ll look at the layout and tell you which one fits.

Do I need backup heat with a cold-climate heat pump?

Any heat pump produces less heat as the outdoor temperature drops, and models differ in how much. Ask for the manufacturer’s capacity ratings at low temperatures, and compare them with your home’s heating needs. Many setups keep a furnace or electric backup for the coldest stretches. We’ll go through the ratings and the backup options before you choose.

Is a whole-house humidifier worth installing?

If winter leaves the house with static shocks, dry air, and cracking woodwork, it can help. The right size depends on the home’s ductwork and how tight the house is, and a humidifier that doesn’t match the house either does nothing or adds too much moisture. We’ll check the system first and tell you if it’s worth it.

What should I do to get a seasonal or second home ready?

Book a furnace or AC tune-up before you arrive rather than after. Ask us to check the thermostat settings, filters, condensate lines, and the system’s startup, and consider a smart thermostat so you can hold a safe minimum temperature while the house sits empty.
