Frequently Asked Questions

What are signs I need a new water heater?

If you notice rusty water, loud rumbling noises, or your system is more than 10–12 years old, it may be nearing the end of its lifespan. A new water heater can improve efficiency and provide more reliable hot water.

How often should I schedule a furnace tune-up?

We recommend once a year, ideally in the fall before the heating season begins. Regular maintenance improves efficiency and helps prevent mid-winter breakdowns

Is professional drain cleaning better than chemical cleaners?

Yes. Store-bought chemicals may provide temporary relief but can damage pipes over time. Professional methods like hydro jetting clear clogs safely and thoroughly.

Do ductless mini-split systems work well in Michigan homes?

Absolutely. Mini-splits provide flexible, efficient heating and cooling in areas where installing ductwork isn’t practical. They’re a great choice for additions, older homes, or targeted comfort zones.
