What Howell weather does to HVAC
Howell's climate swings hard. January lows average in the mid-teens with sub-zero cold snaps, and July highs regularly push into the upper 80s with heavy Great Lakes humidity. That temperature spread is brutal on undersized furnaces and AC units that were never load-calculated for the home they're installed in.
Homes we work on in Howell
Downtown Howell is dense with pre-1940 homes: gravity-converted furnaces, plaster walls, and undersized returns are normal. Marion Township and Oak Grove skew newer with 1990s-and-later construction on slab or full basements, where we usually see aging 80% furnaces and original builder-grade AC that's finally at end of life. Lake Chemung and Thompson Lake homes add their own moisture control problems.
HVAC problems we see most in Howell
After years of service calls in and around Howell, these are the failures we're called out for again and again.
Cracked heat exchangers
Older 80% AFUE furnaces in downtown Howell homes are the most common culprit. We test with a combustion analyzer, not a flashlight.
Frozen AC coils
Undersized returns in 1990s Marion Township builds restrict airflow. The fix is usually adding return capacity, not adding refrigerant.
Water heater sediment failure
Howell's hard water is rough on tank bottoms. Most water heaters here don't make it past year 10 without a flush schedule.
Lake-home humidity
Thompson Lake and Lake Chemung crawlspaces need dedicated dehumidification, not just a bigger AC. We size for latent load.
Howell know-how
From the historic Livingston County Courthouse square and Grand River Avenue businesses, out to homes along Thompson Lake, the Howell Melon Festival grounds, and the Howell school corridor, we know the neighborhoods and the equipment most commonly installed here.
Permits & inspections: Mechanical permits in Howell are pulled through the City of Howell Building Department for city addresses and through Livingston County for most township work. We handle permit filing, inspections, and any Consumers Energy or DTE coordination for gas line changes.

Questions Howell homeowners ask us
How fast can Great Lakes Comfort get to my Howell home for an emergency?
Because our shop is inside the city, most emergency calls in Howell see a technician within 30 to 60 minutes during business hours, and same-day after hours whenever possible.
Do you pull the mechanical permit for furnace or AC installs in Howell?
Yes. Every full furnace or AC installation in the City of Howell or Livingston County includes a properly filed mechanical permit and a final inspection. That paperwork protects your homeowner's insurance and any future sale.
What furnace brands do you install in Howell homes?
We're an authorized AirQuest dealer and install Goodman equipment as well. Both are workhorse brands with parts available locally in Livingston County, which matters when it's 5 degrees out and something needs a warranty part today.
My Howell home is on a well. Does that affect my water heater?
Yes, and it's one of the top reasons water heaters fail early here. Hard well water builds sediment fast. We size accordingly and often recommend an annual flush or a whole-home softener discussion before the replacement.
Do you service commercial HVAC in downtown Howell?
We do. Small storefronts, offices, and restaurants along Grand River regularly use us for rooftop unit service, walk-in cooler repair, and light commercial installs.
