AC Installation

Whether your current AC has finally given out or you're upgrading to a more efficient system, a new air conditioner is one of the most impactful investments you can make in your home's comfort. ACT Heating & Cooling has been installing air conditioners for Billings homeowners since 1992, with a thorough home assessment, honest equipment guidance, and a firm written quote before any work is scheduled.

Installation Done Right Starts Before the Install

A new air conditioner is only as good as the installation behind it. An undersized unit runs constantly and never quite cools your home. An oversized unit short-cycles, cooling too fast, shuts off, and never properly reduces humidity. Either way, you lose comfort and efficiency, and you're paying for a system that isn't performing.

ACT takes a different approach. Before recommending any equipment, we analyze your home's size, construction, insulation, existing ductwork, and your specific comfort goals. The system we recommend is the one that's right for your home, not just the easiest option to quote.

Once we've identified the best fit, everything goes into writing. Our Homeowner Installation Proposal is a firm, itemized quote, not a vague estimate with room to grow. The price on paper is the price on your invoice. That's been our standard since day one, and it's what more than 25,000 Billings homeowners have come to expect from us.

Is It Time for a New Air Conditioner?

Not sure whether you need a repair or a full replacement? Here's how to tell when the math tips toward a new system:

• Your AC is 15 years or older — Most central air conditioners have a service life of 15–20 years. An aging system that's starting to struggle is often better replaced than repeatedly repaired.
• Repair costs are climbing — If a single repair costs more than half the price of a new system, replacement is usually the smarter long-term investment.
• Your energy bills keep rising — Declining efficiency is often the first sign a system is on its way out. A new high-efficiency unit can make a meaningful difference in your monthly utility costs.
• Your home doesn't cool evenly — Hot spots, rooms that won't reach temperature, or humidity that feels impossible to control all point to a system that's losing its ability to do the job.
• You've had multiple repairs in the past few years — Recurring breakdowns aren't bad luck. They're a pattern.
• Your refrigerant is R-22 — If your existing system runs on R-22 (Freon), it's pre-2010 equipment. R-22 has been phased out and is increasingly expensive to service. Replacement is typically the right call.

Not sure which way your situation falls? ACT will give you an honest assessment, including a straightforward comparison of what repair versus replacement actually costs for your specific system.

Start online or call us at (406) 248-5732. We'll schedule a visit to your home at a time that works for you, with no charge for the assessment.

2. We Assess Your Home

An ACT comfort advisor visits to evaluate your home's specific cooling needs, square footage, construction, insulation, existing ductwork, sun exposure, and your comfort priorities. This is how we make sure the system we recommend is the right size and the right fit, not just a standard recommendation.

3. You Receive a Firm, Written Quote

We present your options clearly, with firm pricing for each. The Homeowner Installation Agreement means the number on paper is the number on your invoice. No add-ons, no line items that appear on install day.

4. You Choose, On Your Timeline

We don't pressure. Take the time you need to review your options, compare the models, and decide what's right for your home and budget. Questions are welcome.

5. Professional Installation

Our experienced installation crew arrives on time, protects your home, and does the job right. They'll test the system thoroughly before leaving and walk you through everything you need to know about your new equipment.

6. You're Covered

Your new Amana system is backed by the manufacturer's warranty from day one. If you've added the Pacesetter upgrade, you have 10 years of both parts and labor protection. We register your equipment and make sure all warranty documentation is in order before we leave.

What to Expect on Installation Day

Most central AC replacements are completed in a single day. Here's what the process typically looks like:

• Removal of the existing outdoor unit — Our crew handles full removal and responsible disposal of your old equipment.
• Inspection of existing refrigerant lines and ductwork — Before the new unit is installed, we verify that your existing infrastructure is in good condition and compatible. If we find anything that needs attention, we'll tell you before we proceed.
• Installation of the new outdoor condensing unit — Mounted, leveled, and secured to manufacturer specifications.
• Refrigerant line connection and system charging — Properly charged to factory specifications for peak efficiency.
• Electrical connections and system testing — Full system test to confirm proper operation, airflow, and cooling performance before we call it done.
• Walkthrough with you — We walk you through your new system, explain basic operation and filter maintenance, and answer any questions before we leave.

A new air conditioner is a significant investment, and it shouldn't have to wait until you've saved the full amount — especially when your current system has already failed. ACT offers financing options to help you get the right system for your home on terms that work for your budget.
