Heating & Cooling in Jonesville, MI
The crossroads of the county — and a gas supplier we will not guess at
At the US-12 and M-99 junction, out along the township roads, and across the 49250 addresses that call themselves Mosherville.
Jonesville, Michigan is the second largest place in Hillsdale County at about 2,176 people. It became a city in 2014 — before that it was a village, and plenty of people here still say village. This is Jonesville, Michigan, not the one in Indiana.

Housing Age and Heating Fuel
There is no published town-level breakdown of housing age or heating fuel for Jonesville, so we are not going to produce one. What is published is the county: 21,490 housing units, of which 5,735 — 26.7 percent — were built in 1939 or earlier, against 14.5 percent for Michigan as a whole (ACS B25034). And of 17,858 occupied units, 44.1 percent heat with natural gas against 36.2 percent on bottled, tank or LP gas, where the state figures are 75.2 and 8.6 percent (ACS B25040).
For a Jonesville address the practical reading is directional rather than statistical. The gas main follows density, so a house near the junction is more likely to be metered than one several miles out a township road — but the tank in the side yard is the reliable indicator, not the postcode. And the county's pre-war share means old ductwork, hydronic systems still in service, and furnaces sized for a version of the house that no longer exists are all normal findings here.
Where We Work
Jonesville sits at the junction of US‑12 and M‑99, and we cover the town, the township roads either side, and the 49250 addresses that think of themselves as Mosherville — which has a PO-box-only ZIP and takes its delivery out of Jonesville. Those are exactly the addresses national HVAC sites lose, because address-matching software handles PO-box ZIPs badly.
The practical difference between them is the fuel. In town, more of the housing is on the gas main. Out on the township roads it is more often a tank, more often a private well, and a longer driveway — which matters for propane delivery scheduling more than people expect.
Who Bills You, and Which 2026 Rebates You Can Claim
This is where a Jonesville address differs from a Hillsdale one, and where we are going to be explicit about the limit of what we know.
| Service | In Jonesville |
|---|---|
| Electricity | Consumers Energy. Hillsdale BPU is municipal and serves only inside the City of Hillsdale, so a Jonesville address is a Consumers electric customer and the Consumers electric measures apply. |
| Natural gas | Not confirmed. We have sourced that Michigan Gas Utilities Corporation supplies Hillsdale and Coldwater. We have not sourced the supplier for Jonesville, and we are not going to guess. Read the name on your bill. |
| Propane | An unregulated dealer of your choosing. No utility rebate, and no Winter Protection Plan coverage. |
Why the gas answer is worth two minutes of your time
Consumers Energy's 2026 measures pay gas customers $100 for a 95–96.99% AFUE furnace and $300 for 97% and above. If Consumers is not your gas supplier, those do not apply — and a quote with one deducted is a quote that is wrong. In this county that error is easy to make, because the supplier changes between towns. The name is on your bill.
On the electric side, being a Consumers customer opens the 2026 electric measures: $300 for an air-source heat pump at 15.2+ SEER2, $350 for a ductless mini-split, $150 or $300 for central air conditioning, $65 for an AC tune-up between 1 April and 30 September, and $50 or $100 for a smart thermostat. And DTE does not serve Hillsdale County, so any DTE rebate advertised for a Jonesville address is wrong.
Common Furnace and Propane Problems
On the NOAA 1991–2020 normals for the nearest long-record station, Hillsdale County runs to 6,469.8 heating degree days a year with a January mean minimum of 17.5°F, and December, January and February carry about 53 percent of the annual demand by our arithmetic. Jonesville is in IECC climate zone 5A, "Cold", the same as the rest of the county.
Which produces the same seasonal pattern seen countywide: a marginal furnace runs through a mild autumn without complaint and fails in the second week of January. On tank-fed addresses the characteristic call is not a broken furnace at all but an empty tank — and per the Propane Education and Research Council, the gas must not go back on after a run-out without a professional leak check, and a homeowner should never turn it on at the tank themselves.
Frozen pipes follow the same calendar. Michigan MiReady guidance: hold at least 55°F when you are away, thaw with a hair dryer only and never a torch, and know that a small crack can leak on the order of 250 gallons a day.

Michigan-wide figures from a published contractor guide, not Jonesville quotes. Labour alone typically runs $1,500 to $3,500. Full detail on what things cost.
Off the gas main, MiPropane pays $250 per unit toward an ENERGY STAR propane furnace of at least 40,000 BTU, a storage or tankless water heater, or a boiler — on condition it replaces electric or fuel oil equipment, uses a Michigan-licensed installer, and is not paired with a heat pump. Installed and applied for during 2026.
Nothing federal in 2026
The Energy Efficient Home Improvement Credit (25C) applies only to property placed in service before 31 December 2025, and 25D is likewise unavailable after that date, per the IRS. A quote with a $2,000 federal credit deducted is short by $2,000.
And the exclusion that reaches a large minority of addresses here: Michigan's Winter Protection Plan prevents shutoff from 1 November to 31 March for customers 65 and over, MDHHS assistance recipients and households at or below 150 percent of the federal poverty level — but only for MPSC-regulated gas and electric companies. It does not cover propane or fuel oil.
About Jonesville
Jonesville sits at the junction of US‑12 and M‑99 with the Jonesville Mill Pond in the middle of town. It only became a city in 2014 — before that it was a village, and plenty of people here still say village. Its pupils go to Jonesville Community Schools.
Jonesville sits where US‑12 and M‑99 cross, with its mill pond in the middle of town, about 2,176 people, and Jonesville Community Schools serving the families here. It became a city in 2014; before that it was a village, and the older habit of calling it one has not fully gone away.
US‑12 through here is the old Chicago Road, and following it west brings you to Allen at the M‑49 crossing — known along that corridor as the antique capital of Michigan. North on M‑99 is Litchfield, where the road meets the northern terminus of M‑49 and the North Country National Scenic Trail runs through the middle of town. South on M‑99 is Hillsdale, the county seat.

Jonesville HVAC FAQ
Who supplies gas and electricity in Jonesville, MI?
Electricity outside the City of Hillsdale is Consumers Energy, per the Michigan Public Service Commission’s published service-territory data — Hillsdale’s municipal Board of Public Utilities serves only inside that city’s limits, so a Jonesville address is a Consumers electric customer. On the gas side we have confirmed that Michigan Gas Utilities Corporation supplies Hillsdale and Coldwater, but we have not confirmed which company supplies the main in Jonesville, so we are not going to state it. Check the supplier name on your own gas bill before anyone deducts a rebate from a quote — it decides whether the Consumers gas measures apply to you.
Is Jonesville a city or a village?
A city, since 2014. Before that it was a village, and plenty of people here still say village. It is the second largest place in Hillsdale County at about 2,176 people, well behind Hillsdale at 8,036 and ahead of Litchfield at 1,399. Children go to Jonesville Community Schools. The change matters less for heating than the geography does, but it is the kind of detail that tells you whether a page was written by somebody who has been here.
What does a furnace replacement cost in Jonesville?
Installed, in Michigan in 2026: roughly 3,200 to 5,500 dollars for a standard-efficiency 80 percent AFUE single-stage furnace, 4,500 to 7,200 for a mid-efficiency 92 to 95 percent AFUE two-stage, and 6,000 to 9,500 or more for a high-efficiency 96 to 98 percent AFUE modulating unit, including permits and removal of the old equipment. Labour alone typically runs 1,500 to 3,500. Those are Michigan-wide ranges from a published contractor guide, not Jonesville quotes, and we label them that way rather than dressing them up as local numbers.
Do you cover Mosherville and the addresses on the 49250 ZIP?
Yes. Mosherville has its own PO-box ZIP but its delivery runs out of 49250, so a good many addresses that think of themselves as Mosherville carry a Jonesville postal address. Those are the addresses that national HVAC sites lose, because address-matching software handles PO-box ZIPs and unincorporated communities badly. They are perfectly easy to drive to.
Is my Jonesville house more likely to be on propane or natural gas?
Countywide the split is 44.1 percent natural gas against 36.2 percent bottled, tank or LP gas, per US Census ACS table B25040 — and there is no published breakdown at town level, so we are not going to invent one. What can be said is directional: the gas main runs where population density justifies laying it, so a built-up address near the US-12 and M-99 junction is more likely to be metered than a place several miles out on a township road. The tank in the side yard is the reliable indicator, not the postcode.
