Spring is in the air. Get the jump on it by scheduling your air conditioning service or repairs early. We can handle your seasonal maintenance needs, offer duct cleaning, install ductless mini-split air conditioners and more.

We believe that a dependable air conditioning system which operates efficiently and effectively is a necessity. Montana residents can rely on us to keep them comfortable and cool through the summer heat. When an air conditioner breaks down in the middle of the summer heat it's a big problem, taking preventative measures to ensure this doesn't happen is a priority. Regular maintenance on your system can prolong a unit's life and efficiency so don't wait until your unit breaks to call us.

To help you notice an issue before it becomes a bigger problem we have included some tell-tale signs to watch out for:

Low Air Flow

A decline in the speed at which air moves through the vents can be a big problem. Usually this means cold air is trapped inside of the system, which can cause the coils to freeze. When the system has to work harder to blow out air, efficiency decreases, and your bills will increase.

Reduced Cooling

When your AC system does not provide the relief you need, it suggests low refrigerant and an overheating of parts. This can be problematic. If you notice this, call an AC expert right away. This is another problem that leads to lower efficiency. Save yourself money in the long run by taking care of the issue when it occurs.

Short Cycling

Does your air conditioner turn on and off multiple times a day without running for very long? This is called short cycling, and is a clear indication something is wrong. A qualified professional can diagnose the cause of this issue and take the steps necessary to fix it.


Noises such as humming, screeching, and buzzing are indicative of a number of potential issues. Typically, these sounds will start and stop with the starting and stopping of the air conditioner. Strange noises should never be ignored as it could lead to some serious damage.

Higher Bills

If you are suddenly paying more for cooling, you have an issue on your hands. Sometimes this is the only sign of a problem, so it is important to pay attention to it. If you are not running your AC more than you normally do, but find yourself with a higher bill, it's time to call a qualified technician.
