    Air Conditioning Repairs

    When your air conditioner stops working, you need someone you can trust to show up fast, diagnose the problem honestly, and fix it right the first time. That's exactly what ACT Heating & Cooling has been doing for Billings homeowners for over 30 years.

    We're Billings' AC Repair Experts

    We're not a call center dispatching strangers. ACT Heating & Cooling is a locally owned company based right here in Billings, and we've built our reputation one home at a time. With more than 25,000 residential customers across the Billings area, chances are your neighbors already know our name.

    When your AC goes down, especially during a Montana summer that hits without warning, you deserve a straight answer, a fair price, and a technician who treats your home like their own. That's the ACT standard, and it hasn't changed since day one.

    How AC Repair Works With ACT

    We've built our repair process around one simple idea: no surprises.

    1. Book Online or Call Us

    Schedule your appointment online or give us a call. After hours? Our voicemail is monitored and includes the direct number for our on-call technician.

    2. We Thoroughly Diagnose the Problem

    A skilled ACT technician arrives at your home and performs a complete inspection of your air conditioning system. No guessing. No throwing parts at the problem.

    3. You Get a Clear Price Before Any Work Begins

    Once we know what's wrong, we explain it in plain language and give you a firm price. You decide how to proceed. No pressure, ever.

    4. We Fix It Right

    If you give us the green light, we get to work. Our goal is to get your home comfortable again as quickly as possible.

    Straightforward, Honest Pricing

    We believe you should know what you're paying before anyone touches your system.

    Diagnostic / Trip Fee

    • Billings: $125
    • Laurel & Lockwood: $150

    This fee covers the technician's visit and full system diagnosis. If repairs are needed, you'll receive a clear, itemized price before any work begins. Repair costs are the same whether you call us at 9 AM or 9 PM.

    After-Hours Emergency Service: AC problems don't keep business hours, and neither do we. We offer after-hours emergency service for homeowners who can't wait. Our technicians are on-call and ready to help when you need it most.

    Is It Time to Call for AC Repair?

    Not sure if your system needs a repair or just some attention? Here are the most common signs Billings homeowners notice before their AC gives out:

    • Your AC is running but not cooling — Could be a refrigerant issue, a failing compressor, or a dirty coil.
    • Warm air blowing from vents — Often a sign of low refrigerant or a malfunctioning compressor.
    • Unusual noises — Banging, grinding, or rattling usually mean a mechanical problem that won't fix itself.
    • Short cycling — The system turns on and off rapidly, which strains components and drives up your energy bill.
    • Water or ice around the unit — Ice buildup or pooling water can indicate blocked drainage or refrigerant problems.
    • Suddenly higher energy bills — An inefficient system works harder and costs more to run.
    • Weak airflow — Could point to a failing blower, blocked ducts, or a dirty filter.

    If you're noticing any of these, don't wait. Small issues become expensive repairs when left alone.

    • Brandon was extremely helpful in helping us selecting a furnace replacement and in the prompt repair of our air conditioner it its 7th year of service. Your 10 years warranty on both our air conditioner and furnace is wonderful coverage. Your installers were outstanding and even detected and fixed a gas leak in the line to our water heater.
