We keep it running smoothly

HVAC Maintenance

The best HVAC repair is the one you never need. A little attention each year before the season changes, before the heat spikes or the cold sets in, keeps your system running efficiently, extends its life, and protects you from the kind of breakdowns that always seem to happen at the worst possible time.

ACT Heating & Cooling has been maintaining heating and cooling systems for Billings homeowners since 1992. We know what your system needs, and we'll tell you honestly if anything needs attention.

A Well-Maintained System Is a Reliable One

Heating and cooling equipment doesn't fail randomly. Most breakdowns stem from worn parts, dirty components, low refrigerant, or other minor issues that quietly compound over time until something gives. Annual maintenance is how you find those things before they find you.

More than 25,000 Billings-area homeowners have trusted ACT to keep their systems running. Our Complete Care Tune-Ups are thorough, our technicians are trained to spot developing problems, and we'll always give you a straight answer about what we find and what it would cost to address.

No pressure. No manufactured urgency. Just honest service from a company that's been in this community for over 30 years.

Choose Your Tune-Up

Complete Care A/C Tune-Up — $199

Billings summers are hot, and they hit fast. Our Complete Care A/C Tune-Up gets your cooling system ready before the first heat wave arrives by cleaning coils, checking refrigerant pressures, testing electrical components, and inspecting everything that keeps your system running at peak efficiency.

Schedule in spring and you'll head into summer knowing your AC is ready. Wait until it breaks down in August, and you'll be joining a very long queue.

What's included: Coil cleaning, electrical inspection, refrigerant pressure check, thermostat test, filter replacement, condensate drain cleaning, motor lubrication, and a full system cycle test, plus an honest assessment of anything that needs attention.

Complete Care Furnace Tune-Up — $199

A Montana winter with an unreliable furnace isn't just uncomfortable; it can be urgent. Our Complete Care Furnace Tune-Up inspects and services every critical component of your heating system, from burners and ignition to heat exchanger condition and gas pressure, so you go into winter with confidence instead of crossed fingers.

Schedule in the fall, August through October, and you'll have your pick of appointment times. Once the cold arrives and furnaces start running in earnest, our calendar fills up fast.

What's included: Burner and pilot assembly cleaning, filter replacement, blower inspection, thermostat test, gas pressure check, temperature rise verification, combustion chamber inspection, flue draft check, electrical connections, and flame sensor cleaning, plus an honest assessment of anything that develops.

Not Sure Which One You Need?

If your system hasn't been serviced in a while, the answer is probably both. Most Billings homes have a furnace and a central air conditioner that share the same air handler, and both benefit from annual attention.

Scheduling your AC tune-up in spring and your furnace tune-up in fall is the simplest way to stay ahead of problems year-round. Or join the Membership Program, and we'll handle the scheduling for you.

What You Get From Annual Maintenance

Lower Energy Bills

A clean, properly calibrated system runs more efficiently. For a furnace running six months a year in a Montana climate, that efficiency gap adds up.

Fewer Surprise Repairs

Most major HVAC failures start small. Annual maintenance catches developing problems like a worn capacitor, a cracked heat exchanger, or low refrigerant, before they become breakdowns.

A Longer-Lasting System

Neglected systems fail sooner. Well-maintained ones routinely outlast their expected service life by years. That's a significant difference in deferred replacement cost.

Warranty Protection

Many manufacturer warranties require documented annual maintenance. Skipping tune-ups can void coverage you're counting on.

Peace of Mind

Knowing your system was professionally inspected before the season changes is worth something. You go into summer and winter without wondering.
