HVAC service across southeast Michigan
One local crew out of Howell, MI. Same-day furnace, AC, water heater, and commercial work for homes and businesses across nine cities and five counties.
Great Lakes Comfort is a Howell, Michigan HVAC contractor covering a tight radius across Livingston County and the surrounding corridor. We keep our service map deliberate: close enough that a truck can be at your door the same day, and small enough that the technician who installed your furnace is the same one who comes back for the tune-up. If you can drive to our Howell shop inside an hour, we can be at your address inside an hour too.
Nine cities, one local crew
Each city page has its own local content: climate patterns, common housing stock, HVAC failures we see most, permit authority, ZIP codes, and answers to the questions homeowners in that town actually ask us.

Our service map
Based in Howell, Michigan. Livingston County core, with Oakland, Genesee, Washtenaw, and Ingham on the ring.
Five counties, honest coverage
We would rather be a real local option in five counties than a name on a map in twenty. Here is exactly where our trucks run.
Livingston County
Home county. Howell, Brighton, Hartland, Pinckney, Fowlerville, Hamburg, Green Oak, and the townships in between - typically same-day, often same-hour.
Oakland County (west)
Milford, Highland, South Lyon, White Lake, Wixom, Commerce Township. Regular scheduled service and same-day emergency response.
Genesee County (south)
Fenton, Linden, Argentine Township. The lake communities south of Flint.
Washtenaw County (north)
Ann Arbor, Dexter, Chelsea, Whitmore Lake. Residential installs, replacements, and service.
Ingham County (east)
Lansing, East Lansing, Okemos, Meridian Township. Replacement work and light commercial.
Every service is available in every city
We do not carve up service offerings by ZIP code. Whether you are in downtown Howell or a Lansing bungalow, you get the same crew, the same equipment options, and the same warranty.

How do I know if my address is in your service area?
If you are within roughly an hour of Howell, Michigan - anywhere in Livingston County or the nearby edges of Oakland, Genesee, Washtenaw, or Ingham County - you are almost certainly in. When in doubt, call us. If we cannot cover you we will tell you and, when we can, point you to a contractor who can.
Do you charge more to service farther cities like Ann Arbor or Lansing?
Our diagnostic and service rates are the same across our entire coverage area. What changes with distance is scheduling - we route farther calls efficiently, so a non-emergency Ann Arbor or Lansing visit may be grouped into a particular day of the week rather than same-hour.
Is same-day service really same-day across all these cities?
For Livingston County - Howell, Brighton, Hartland - yes, essentially always during business hours. For farther cities we prioritize emergency no-heat and no-cool calls same-day, and schedule non-emergency work within one to two days.
Do you serve commercial customers in every city on this list?
Yes. Rooftop unit installation, repair, and maintenance, plus walk-in refrigeration service, are available anywhere in our coverage area. Commercial customers typically get on a preventive-maintenance schedule so we are the ones catching problems before they become closures.
Are you licensed for work outside Livingston County?
Michigan mechanical licensing is state-wide. Our MI Mechanical License No. 7119201 is valid in every city and county we serve, and we pull local permits through the appropriate building department for each municipality.
My city is not on the list. Will you still come out?
Probably, yes. Our named pages cover the cities we work in most, but we regularly serve Pinckney, Fowlerville, Hamburg, Whitmore Lake, Dexter, Chelsea, White Lake, Wixom, Commerce Township, Linden, Okemos, and other nearby towns. Call and ask.
