Questions we hear in the Flathead
Comfort Club · Reviews · Heat pump rebates
What does HVAC stand for?
Heating, ventilation, and air conditioning. In a Flathead Valley home that usually means a furnace, air conditioner, heat pump, or mini split — plus the airflow that moves conditioned air through the house.
How often should I change my furnace filter?
Every 30 to 90 days is the usual range (Trane and most manufacturers agree). In Montana, check monthly during heating season. Pets, wildfire smoke, and dusty shops mean more frequent changes. A clogged filter is one of the most common reasons a system overheats, ices, or short-cycles.
How often should HVAC be serviced?
Plan on a furnace tune-up in the fall before heating season, and AC or heat-pump service in spring before cooling season. Heat pumps that run year-round do best with two visits a year. Annual service is the standard recommendation from manufacturers and local Montana HVAC guides — especially here, where winters are long and hard on equipment.
How long do furnaces, air conditioners, and heat pumps last?
With regular maintenance, furnaces often last about 15–20 years, central air conditioners about 12–15 years, and heat pumps about 15 years. Age alone isn’t the whole story. Repair history, installation quality, and how hard Flathead winters work the system matter more than a round number.
Should I repair or replace my HVAC system?
Repair makes sense when the unit is relatively young, the fix is straightforward, and parts are still available. Replacement is worth talking about when the system is past mid-life, repairs keep stacking up, or it’s struggling to keep up on the coldest nights. We’ll price the repair first and tell you honestly if the money is better spent another way.
Why isn’t my air conditioner cooling — or why is it icing up?
Common causes are a dirty filter, restricted airflow, a failing blower, low refrigerant, or dirty coils. Ice on the lines or coil is a “stop and call” problem — running an iced unit can damage the compressor. Don’t keep resetting it and hoping.
Why does my system turn on and off so quickly?
That’s short cycling. It can be a dirty filter, a bad thermostat, an oversized unit, a flame-sensing issue on a furnace, or a refrigerant problem on cooling. Short cycling wears parts out fast and doesn’t actually heat or cool the house.
My thermostat isn’t working. What should I check?
Start with fresh batteries and make sure it’s set to heat or cool, not off. If the screen is blank, the display jumps, or the system ignores the setpoint, it may be the thermostat — or it may be the equipment not responding. We’ll check both so you don’t replace the wrong part.
What’s the difference between a furnace and a heat pump?
A furnace burns fuel (usually gas) to make heat. A heat pump moves heat — it cools in summer and heats in winter. Mini splits are ductless heat pumps. In this climate, cold-climate or Hyper Heat models matter. A standard heat pump that works in a mild climate is not automatically the right fit for Kalispell.
Do mini splits and heat pumps work in Montana winters?
Yes — if they’re cold-climate equipment. Montana sits in a cold-dry climate zone. Look for systems rated well below zero (MRCOOL Hyper Heat, for example, is rated to −22°F). Generic mini splits that lose capacity at 20°F are a poor match for the Flathead. We can help you pick one, drop-ship a DIY kit, or install it.
What do SEER2 and AFUE mean?
SEER2 is how efficiently an air conditioner or heat pump cools over a season. AFUE is how efficiently a furnace turns fuel into heat. Higher numbers generally mean lower bills, and they can affect rebate eligibility through Flathead Electric or Lincoln Electric.
Do you work on all HVAC brands?
Yes. We service furnaces, AC, heat pumps, and mini splits across the major brands. MRCOOL is the line we partner on for ductless kits, but we install and service other brands as well. If you already have equipment, bring the brand and model if you have it — we’ll work on it.
Why is my boiler not producing heat?
No heat is the most common boiler call. It can be as simple as a thermostat, a tripped switch, or low pressure — or it can be a pump, zone valve, ignition, or combustion problem. Don’t keep resetting a lockout. We’ll diagnose it and tell you what’s actually failed.
What pressure should my boiler be at?
Most residential hydronic boilers sit around 12–15 psi cold, and a bit higher when hot — often in the 18–25 psi range depending on the house. If the gauge is on the floor or climbing into the relief-valve range, call. Low pressure usually means a leak, a failing fill valve, or air in the system. High pressure is a safety issue.
My boiler is leaking. Is that an emergency?
Any active leak is worth a same-day look, especially in winter. Common sources are the pressure relief valve, pump seals, zone valves, fittings, and corrosion. A relief valve that drips steadily often means the system is over-pressurized, not that the valve is “just old.”
What is kettling, and why is my boiler banging?
Kettling is a rumble or knock from scale and debris on the heat exchanger — like a kettle boiling dry in spots. Flathead and well-water minerals make this more common. Banging can also be air in the loops, a failing pump, or water hammer. It’s not something to ignore through another heating season.
Some rooms are hot and others are cold. Is that the boiler?
Often it’s a zone valve, thermostat, pump, or air trapped in a loop — not a dead boiler. Radiant floors, older Kalispell houses, and mixed radiator/baseboard systems each fail in different ways. We’ll trace the zone that’s actually down instead of guessing at the boiler.
How often should a boiler be serviced?
Once a year, before heating season. That visit covers combustion, safety controls, pumps, pressure, leaks, and whether the boiler is short-cycling. A Montana winter is a long run-time. Waiting until the first no-heat night in January is how small problems become freeze-ups.
Do you work on all boiler brands?
Yes. We service, repair, and maintain residential boilers of all common brands, and we hold a Montana state boiler license.
Why do I have no hot water?
On a tank unit, common causes are a tripped breaker, failed heating element, bad gas valve or igniter, a failed thermocouple, or a tank that’s filled with sediment. On tankless, it’s often ignition, a scale-clogged heat exchanger, or a code on the display. We'll tell you what failed and what it takes to fix.
Why is my water only lukewarm?
Dip tubes fail, elements burn out one at a time, thermostats drift, and mixing valves stick. On tankless units, scale from hard water cuts output. Lukewarm water is one of the most common service calls we run in the Flathead.
My water heater is leaking. What now?
A leak at a fitting or T&P valve can often be repaired. Water pooling at the bottom of the tank is urgent: shut the water and the power or gas off if you can do it safely, and call. Standing water around a gas water heater is not a wait-until-Monday problem.
Why is the tank popping or rumbling?
Sediment. Hard water in Northwest Montana drops minerals in the bottom of the tank. The burner boils water under that layer and the tank sounds like popcorn. Flushing and anode-rod service slow it down. Don't ignore it through another winter.
Tank or tankless — which is better?
Tanks are simpler and usually cheaper to keep running. Tankless units heat on demand and can last longer if they’re descaled. Hard water is hard on both, tankless especially. We service tank and tankless, gas and electric.
How often should a water heater be flushed or maintained?
Flush a tank yearly if you can, more often on hard water. Anode rods are often inspected every two to three years. Tankless units need descaling on a schedule or they lose flow and throw codes. Maintenance is cheaper than an emergency no-hot-water call on a holiday weekend.
How long do water heaters last?
Tank units commonly last about 8–12 years here; hard water shortens that. Tankless can go longer with descaling. Age plus leaking, rust at the base, or repeated element/igniter failures is usually the sign the repair isn’t worth it.
Do you offer 24/7 emergency service?
Yes. Heat and hot water don’t fail on a convenient schedule. Call or text (406) 260-2952 any time. You reach us, not a call center, and there are no emergency upcharges just because it’s after hours.
What should I do if the heat goes out in winter?
Check the thermostat, the furnace or boiler switch, and the breaker. Replace thermostat batteries if the screen is dead. If you smell gas, leave the house and call from outside. If the system is locked out, iced, leaking, or blowing cold air, stop resetting it and call us.
What cities do you serve?
Kalispell, Whitefish, Columbia Falls, Bigfork, Evergreen, Somers, Lakeside, Kila, Libby, Polson, Hungry Horse, Eureka, Helena Flats, and Flathead County.
Are you licensed and insured?
