Missoula Generator Installation & Repairs

Generators are an essential part of modern life. A power outage can occur at any time, so it’s important to have a reliable backup system in place to make sure that you and your family are safe and comfortable. At Anderson's Heating, Air Conditioning & Plumbing, our Missoula generator installation and repair technicians can help you choose the best generator for your needs and budget, and we offer a full range of generator services to make sure that you’re never left in the dark.

Call (406) 296-5833 to schedule a generator installation in Missoula or the surrounding areas.

What Size Generator Do I Need?

When choosing a generator, it’s important to make sure that the generator is the right size for your home. A generator that is too small may not be able to power all of your appliances, while a generator that is too big may be more expensive than you need. Our Missoula generator installation experts can help you choose the right size generator for your home.

Generators are measured in watts. You can use a generator sizing calculator to help you determine your power needs, or you can ask one of our Missoula generator installation technicians to help you choose the right size generator for your home.

How Long Do Generators Last?

Most generators will last between 10,000 and 30,000 hours. How long your generator will last will depend on how often you use it and how well it is maintained. If you only use your generator during power outages and you have it serviced regularly, then it should last for many years. If you use your generator often and do not have it serviced, then it may not last as long.

Generator Maintenance & Repair in Missoula

Generators require regular maintenance to keep them running smoothly. If you don’t have your generator serviced regularly, it may not work when you need it most. At Anderson's Heating, Air Conditioning & Plumbing, we offer generator maintenance and repair services to make sure that your generator is always ready to go.

We recommend having your generator serviced at least once a year. During a generator service, one of our Missoula generator technicians will inspect your generator, clean it, and make any necessary repairs. They will also check the oil, air filter, and spark plugs to make sure that they are in good condition.

If you notice any problems with your generator, such as strange noises or a burning smell, you should call for repairs right away. Ignoring a problem will only make it worse, and it may cause your generator to stop working altogether.

The electrician they sent did a great job modifying a system that was already in place and installing a new system along with that."
