AC Installation or AC Replacement?
Replacing your system isn’t just about swapping boxes. It’s about improving comfort, efficiency, and long-term reliability. We install new AC systems for:
- First-time installs in homes without central air
- Replacing older systems that no longer cool reliably
- Upgrading to high-efficiency units to lower utility bills
- Replacing undersized or improperly installed units
Every install starts with a consultation. We inspect your space, evaluate your existing system (if there is one), and explain your best options based on performance, energy usage, and budget. We handle permits, removal of the old system, and complete system testing. You’ll know exactly what you’re getting and what to expect.

Signs It’s Time to Replace Your Air Conditioner
Not sure if it’s time to replace? Here are the most common signs we see that signal it’s time to upgrade:
Age of Your AC Unit
Most air conditioners last around 12 to 15 years. If yours is older, it’s likely operating less efficiently and more prone to breakdowns.
Inconsistent Cooling
If your home has hot and cold spots, or the system struggles to keep up during high temperatures, it may no longer be performing as it should.
Rising Energy Bills
An older or failing system often uses more energy to produce less cooling. If your bills are climbing with no clear cause, your AC could be to blame.
Frequent or Costly Repairs
Needing repairs every season—or paying for big fixes—is a strong sign that replacement may be more cost-effective than continuing patchwork.
Outdated Refrigerant
Systems still using R-22 refrigerant are harder to service and more expensive to maintain. Modern units use safer, more efficient refrigerants.
If you’re on the fence, we’ll give you honest feedback on whether your current unit can be repaired or if a replacement will save you more in the long run.
Post-Installation Support & Maintenance
After installation, we don’t disappear. We offer ongoing AC maintenance services to keep your new system running like it should. That includes seasonal tune-ups, system performance checks, and filter changes. You also get peace of mind knowing we’re nearby and available if anything ever goes wrong.
FAQs
How do I know if I need a new air conditioner or just a repair?
If your system is over 10–15 years old, needs frequent repairs, struggles to keep your home cool, or is driving up energy bills, replacement may be the better long-term option. We’ll inspect the system and give you a clear, honest recommendation based on condition and cost.
What types of air conditioning systems do you install?
We install central air conditioners, heat pumps, and ductless mini-split systems. Each recommendation is based on your home’s layout, existing ductwork, and how it performs during Missoula’s summer conditions.
How much does a new air conditioner cost in Missoula?
Most installations range from $6,000 to $15,000+ depending on system size, efficiency, and any ductwork or electrical updates needed. We provide upfront pricing and offer flexible financing options to make the investment easier.
Do you offer emergency air conditioning service?
Yes. We provide emergency AC repair throughout Missoula and surrounding Western Montana areas, especially during peak summer heat when fast service matters most.
How long does AC installation take?
Most installations are completed in one day. Larger or more complex jobs—like ductwork modifications or full system replacements—may take longer depending on the scope.
What size air conditioner does my home need?
System size depends on square footage, insulation, sun exposure, windows, and airflow. We perform proper load calculations to ensure the system is correctly sized for efficiency and comfort.
Do you service all air conditioner brands?
Yes. Our technicians are trained to work on most major brands and system types, including older units and high-efficiency models.
Why is my air conditioner running but not cooling the house?
Common causes include low refrigerant, dirty coils, clogged filters, airflow issues, or failing components. If your system is running without effectively cooling, it should be inspected to prevent further damage.
How often should my air conditioner be serviced?
We recommend annual maintenance, ideally in spring before heavy use. Regular service improves efficiency, reduces breakdowns, and helps extend the life of your system.
Can wildfire smoke affect my air conditioning system in Western Montana?
Yes. Smoke and poor air quality can clog filters quickly, restrict airflow, and strain your system. During smoke season, more frequent filter changes and upgraded filtration can help protect both your system and indoor air quality.
Do you offer financing for new air conditioning systems?
Yes. We offer flexible financing options for qualifying homeowners to make AC replacement and upgrades more manageable.
What areas around Missoula do you serve?
We serve Missoula and surrounding communities including Frenchtown, Lolo, Bonner, Clinton, Florence, Stevensville, and Polson, with fast response times across Western Montana.
