Rheem has a long-standing reputation for innovation, offering models with advanced features like variable-speed compressors for precise temperature control, and EcoNet® compatibility for smart home integration.

Whether you’re constructing a new building and require a complete cooling solution or your current system is faltering, our certified technicians offer customized installation services designed to meet your unique needs and budget. We also understand that a new AC unit is an investment, which is why we offer flexible financing options, seasonal specials, and comprehensive post-installation maintenance programs, including our Diamond Club, to make the process as smooth and beneficial as possible

Why Invest in a New AC Unit?

Installing a new air conditioning system is not just about replacing old equipment. It is about improving how your home feels, functions, and performs during Western Montana’s warmest months. A modern AC system offers real advantages that go beyond simple cooling.

Lower Energy Costs

Older air conditioners often work harder than they should, driving up energy bills month after month. New systems are built with improved efficiency standards that use less energy to deliver consistent cooling. Over time, those savings can make a noticeable difference in your monthly utility costs.

More Consistent Comfort

If some rooms in your home never seem to cool properly, an aging system may be the reason. New air conditioners provide more even temperature control and improved airflow. The result is a home that feels comfortable from room to room, even during peak summer heat.

Cleaner Indoor Air

As AC systems age, they can circulate dust, allergens, and other airborne particles. Modern systems paired with upgraded filtration help improve indoor air quality. This creates a healthier environment for your family and reduces the buildup of unwanted pollutants inside your home.

Fewer Breakdowns and Repairs

Frequent AC repairs are often a sign that a system is nearing the end of its lifespan. New air conditioners are built for reliability and long-term performance. Installing a new unit can reduce surprise breakdowns and give you peace of mind during the hottest days of the year.

Quieter Operation

Older systems tend to be loud and disruptive as components wear down. Today’s air conditioners are designed to operate much more quietly. This means better comfort without the constant background noise of a struggling system.

Environmentally Responsible Cooling

Many older AC units rely on outdated refrigerants that are no longer environmentally friendly. New systems use modern refrigerants and technology that reduce environmental impact. Upgrading helps lower your carbon footprint while improving efficiency.

Added Home Value

A new, energy-efficient air conditioning system is an attractive feature for potential buyers. It signals that the home has been well cared for and updated with modern comfort solutions. Even if you are not planning to sell soon, it is an investment that adds long-term value.

We're here to help!

Our team will help you select the perfect Rheem model for your specific needs.

Why Homeowners Choose Hellgate for AC Installation

Installing a new air conditioner is a long-term decision, and who installs it matters just as much as the equipment itself. Homeowners across Western Montana turn to Hellgate Plumbing, Heating and Cooling because we focus on doing the job right, not rushing through it.

  • Installation done with intention: We do not take a one-size-fits-all approach to AC installation. Every home is evaluated for size, layout, and cooling demands so the system performs the way it is supposed to from day one.
  • Built for local conditions: Western Montana homes face unique weather swings and temperature demands. Our team installs systems with those conditions in mind, helping prevent short cycling, uneven cooling, and early system failure.
  • Clear expectations from start to finish: We walk you through the process before any work begins so you know what to expect. From system selection to installation day, communication stays clear and straightforward.
  • Long-term system care: Our Diamond Club maintenance program is designed to protect your new investment. Members receive regular maintenance and priority scheduling, helping their new AC system run efficiently and reliably year after year.
  • Respect for your home: A new installation should not leave behind a mess or stress. Our technicians treat your home with care, keep the work area clean, and complete installations with professionalism and attention to detail.

Hellgate is our go-to for plumbing issues! They’re quick to get us on the schedule and have been really helpful helping us trouble-shoot the usual old-Missoula-house issues that come up. I also really appreciate their plumbers being willing to talk through what they are seeing and answer my questions to help me understand the issues. We have done Hellgate’s membership program and feel like it’s really been worth it. Would definitely recommend these guys!

Henry did a great job fixing my dishwasher and old shutoff valves on a previous visit, and he was gracious double-checking the work after another leak scare. He found nothing (whew), and always offers some quick education so I can approach future issues with more knowledge. Two thumbs up

Hellgate very easy to communicate and coordinate with to determine scope of work, estimate, contract, and work scheduling. This include work by the Hellgate HVAC technician as a 3rd party electrician.

Both the Hellgate technical and the electrician were on time and worked without break to complete the work. 

Upon completion the installation and the system operation were explained well by the technician. 

Paperwork supporting e-rebate had already been completed by the HVAC technician.

Very professional. High quality. I will continue to work with Hellgate on plumbing or HVAC needs.
