Furnace Repair, Installation & Replacement

When a furnace stops working, the first question is whether it’s a quick repair or a sign the unit is finished. Our furnace services begin with a diagnosis, so you know the cause and your options before work starts. The more you can tell us on the phone, such as the error light, the noise, or whether it runs at all, the better we can plan the visit.

If the furnace is past saving, we handle furnace replacement and installation: sizing the new unit to the house, setting it up, and testing it. In a place where winters are long enough to be a real part of the year, a furnace sized for your home matters.

Air Conditioning Repair, Installation & Replacement

Eureka gets hot, sunny summer afternoons, and many older houses in town were built without air conditioning in mind. Our air conditioning services include AC repair, new air conditioning installation, and replacement for systems that have run their course, plus a spring check of the outdoor unit, coils, and refrigerant so it’s ready before it’s needed.

If a house has no ducts at all, a ductless system may get you cooling without tearing into walls.

Ductless Mini-Split Installation & Repair

Older homes, cabins, shops, and additions often have the same problem: they were never built with ductwork. Our ductless mini-split systems bring heating and cooling to those spaces with a compact indoor unit and a small line set through the wall. That includes mini-split installation, plus repairs later on, whether it’s one indoor unit or several.

For a house that has relied on baseboard heaters, wall units, or a wood stove, a mini-split can add efficient year-round comfort without a major renovation.

Heat Pump Installation, Repair & Maintenance

A heat pump heats and cools from one system, and our heat pump services run from choosing the equipment to long-term upkeep. We work with ducted and ductless systems and cold-climate models.

In the Tobacco Valley, picking the right model is the whole conversation. We’ll review a unit’s low-temperature capacity, discuss the backup heat that goes with it, and tell you plainly whether a heat pump suits your house.

HVAC Maintenance Plans & Seasonal Tune-Ups

Because Eureka isn’t around the corner from our shop, planning ahead makes sense. Our maintenance agreements schedule furnace maintenance and AC maintenance before the season rather than during an emergency, and cover furnaces, air conditioners, and heat pumps. A tune-up in the fall is a better time to find a worn part than the first cold morning.

Whole-House Humidifier & Dehumidifier Installation

Dry indoor air in the winter and a stuffy, damp house in summer are both problems we can address. Through our additional comfort services, we install and repair whole-house humidifiers and dehumidifiers matched to the home’s ductwork and size, so humidity control runs automatically.

Indoor Air Quality & Whole-House Air Purifiers

Wood smoke, wildfire smoke, dust, and pet dander can all end up in a house’s air. Our indoor air quality solutions include better filtration, whole-house air purifiers, and ventilation upgrades. We start with what you’re noticing and what the system can handle, then recommend equipment to fit.

Duct Sealing, Duct Repair & Custom Ductwork

Ducts that leak or have come apart waste heating and cooling and leave some rooms behind. We inspect, seal, and repair ductwork, and our custom sheet metal shop in Kalispell builds ducts, transitions, and fittings when a standard part can’t do the job. This matters in older buildings, where the layout rarely matches what’s on the shelf.

Zone Control Systems

If one room is always cold and another is always warm, zoning may be the answer. Zone control is part of our broader HVAC services: dampers and thermostats that divide one system into areas, which suits additions, finished basements, and rooms with a lot of glass.

Smart & Programmable Thermostat Installation

A smart thermostat lets you check on and adjust the heat from your phone, which is useful for a cabin or second home you aren’t staying in. We install and set up smart and programmable thermostats, replace failed units, and make sure they work with your furnace, AC, or heat pump.

Gas Fireplace & Patio Heater Installation

A gas fireplace is an easy, clean replacement for a wood-burning one, and a patio heater extends a deck or patio into cooler evenings. Both installs include the gas line and venting, and we also service fireplaces that are already in the house.

Commercial HVAC Installation, Repair & Maintenance

Shops, restaurants, lodging, offices, and public buildings across town all depend on heating and cooling that works. For commercial HVAC, we can install new equipment, repair or replace what’s failing, and keep a maintenance schedule going. If your business fills up for Rendezvous Days, the Lincoln County Fair, or the summer event season, we’ll plan maintenance ahead of it, because a service call is a lot easier to schedule in advance than after a failure.

Why Eureka Homeowners and Businesses Choose General Sheet Metal

The company has been in the same family’s hands since 1942. Our technicians carry Bryant Certified Ductless Pro and NATE certifications, and we’re members of the Flathead Building Association. We fabricate custom ductwork in-house at our Kalispell shop, so we aren’t subcontracting the hard parts of a job. For a customer in Eureka, that means one company that can handle the repair, the replacement, and the metalwork.

Eureka HVAC Repair & Maintenance Questions, Answered

You’re based in Kalispell. How does service work in Eureka?

My furnace turns on and off every few minutes. What’s wrong?

That’s called short cycling. Common causes include a dirty filter or restricted airflow, a faulty flame sensor, an overheating limit switch, or a thermostat issue. Replace the filter first, then call us if it continues. Repeated short cycling is hard on the furnace.

Is a ductless mini-split better than baseboard or electric wall heaters?

A mini-split is a heat pump, which moves heat instead of generating it directly from electricity, so it typically uses less electricity for the same comfort. It also cools in the summer, which baseboards can’t. We’ll go over the rooms, the layout, and your heating costs before recommending equipment.

Can I add air conditioning to a house that has no ducts?

Yes. A ductless mini-split cools without ductwork, either a single room or several rooms with multiple indoor units. If you already have ducts in good shape, central air conditioning is another option, and we’ll tell you which one fits.

Why is one part of my house always colder than the rest?

Common causes are leaky or undersized ducts, a closed or blocked vent, a system that isn’t balanced after an addition, or poor insulation. We check airflow room by room. Depending on what we find, the fix might be a damper adjustment, duct repair, zoning, or a ductless unit for that space.

How often should I change my furnace filter?

Follow the filter and furnace manufacturer’s instructions, and check it monthly during heavy use. A clogged filter restricts airflow and is one of the most common reasons a furnace misbehaves.

Do you maintain HVAC systems for businesses in Eureka?

Yes. We install, repair, and maintain commercial HVAC equipment for shops, restaurants, lodging, and offices. A maintenance plan is the easiest way to avoid a breakdown during your busy season.
