Montana summers can be hot, and a broken air conditioner is the last thing you want. Monarch Heating & Cooling provides professional AC installation, fast repair, and thorough maintenance to keep your home cool and comfortable even on the hottest days.

We work with energy-efficient systems from top brands like Mitsubishi and Lennox, ensuring you get reliable cooling without sky-high electric bills. Our installation process starts with a detailed home evaluation—we check ductwork, insulation, and load requirements—so your new AC is perfectly matched to your home. For repairs, we arrive on time, diagnose the issue, and explain your options clearly before any work begins. No surprise fees, no unnecessary upsells.

Routine AC maintenance from our team can prevent unexpected breakdowns and keep your system running at peak performance. We clean coils, check refrigerant levels, test electrical components, and replace worn parts before they fail. As a locally trusted, veteran-owned company, we treat your home with respect and get the job done right the first time.

Heat pumps offer an energy-efficient alternative to traditional furnaces and air conditioners, providing both heating and cooling from a single system. At Monarch Heating & Cooling, we are experts in heat pump installation, repair, and maintenance for residential and commercial properties in Manhattan.

Ductless mini-splits and central heat pumps are ideal for Montana’s climate because they work efficiently in cold weather when properly sized. We help you choose the right system—whether you are adding a room, finishing a basement, or replacing an old HVAC system. Our Mitsubishi and Lennox heat pumps deliver quiet, consistent comfort with lower operating costs.

If your existing heat pump is not keeping up, we troubleshoot everything from refrigerant leaks to compressor issues and frozen coils. We also offer preventive maintenance plans to keep your system running efficiently year-round. With 24/7 emergency service and the Monarch Shield Warranty on select equipment, you can rest easy knowing your home will stay comfortable no matter the season.
