Let’s be real…

Is a furnace tune-up necessary?

There are two very real reasons why an annual tune-up is necessary!


Many models of furnaces use combustible materials to function. If something goes wrong in your furnace that causes incomplete combustion, it may result in the release of carbon monoxide. Our trusted professionals know what to look for and will check for things like:

  • A cracked combustion chamber
  • Improper pressure in the gas line
  • Poor ventilation

There are many things that can lead to the release of excess carbon monoxide. Our team knows how to catch and fix them before they turn into costly and potentially dangerous problems.


For many furnace manufacturers, regular maintenance is required for continued warranty coverage. If you don’t have proof of these services, you may be stuck paying in full for a repair or a whole-system breakdown. Lake Michigan Heating, Cooling, Plumbing will get you the paperwork needed to honor your warranty!
