HVAC FAQs

We recommend servicing your furnace and air conditioner once per year—ideally in the fall for heating and in the spring for cooling. Preventative maintenance keeps your system running efficiently and helps prevent unexpected breakdowns. Explore our Maintenance Tips for more on what to expect during a tune-up.

In most homes, we recommend changing your air filter every 1–3 months. If you have pets, allergies, or a higher volume of foot traffic, you might need to replace it more often. A dirty filter restricts airflow and makes your HVAC system work harder, which increases energy use and shortens its lifespan.

A frozen AC unit can be caused by a dirty filter, low refrigerant, or restricted airflow due to blocked vents or dirty coils. Turn off your system and let it thaw before calling for service. If it happens repeatedly, it may be time for professional AC repair.

There’s no one-size-fits-all answer. Proper sizing depends on your square footage, insulation, window count, and more. Installing a unit that’s too big or too small leads to inefficiency and comfort issues. We offer custom load calculations as part of every new system installation.

SEER stands for Seasonal Energy Efficiency Ratio. It measures cooling efficiency—the higher the number, the more efficient the system. New units in Montana must meet a minimum SEER rating (usually 14 or higher), but high-efficiency models can go up to SEER 20+. We can walk you through options during an AC upgrade.

If your unit is over 12–15 years old and facing frequent repairs, it may be more cost-effective to replace it. A general rule is: if repairs cost more than 50% of the price of a new system, consider replacement. Learn more on our HVAC Retrofitting page.

Yes—in many cases, we can retrofit an AC coil and condenser to work with your current furnace. It depends on your ductwork and system design. We specialize in custom retrofitting solutions for older homes in Great Falls.

Banging, screeching, or rattling noises often indicate a loose component, worn belt, or airflow problem. Don’t ignore unusual sounds—they’re usually the first sign of a larger issue. Schedule a furnace repair or AC inspection before things get worse.

We install whole-house air purifiers, humidifiers and dehumidifiers, and smart thermostats to improve comfort and reduce allergens, dust, and mold in your home. Ask us about a custom air quality assessment.

Homeowners can (and should) replace filters, check thermostat settings, and keep vents clear. But deeper tasks—like coil cleaning, refrigerant checks, burner inspections, and duct balancing—should be handled by our licensed technicians during annual service.

With regular maintenance, furnaces typically last 15–20 years and central AC systems around 12–15 years. If your system is nearing the end of its lifespan, consider planning for a replacement to avoid downtime during a heatwave or cold snap.

Yes—especially in our variable Montana climate. A smart thermostat lets you control your HVAC remotely and adjust schedules based on your daily routine. Many homeowners see energy savings of 10–20% annually.

Start with a clean filter, sealed ductwork, and properly programmed thermostat. Also consider upgrading to a high-efficiency furnace or exploring zoning options. Learn more about energy-saving upgrades we offer in the Great Falls area.
