Heating and Cooling in Sullivan, MO

Sullivan sits on I-44 where Highway 185 meets the interstate, straddling the Franklin and Crawford county line in ZIP 63080. It counted 6,906 people in the 2020 census. We are in Hermann, on the far side of a lot of hills, so this page will not pretend we are the shop around the corner.

Why the Highway 185 drive changes how you book

Our route runs east on Highway 100 to New Haven, down Routes C and YY, then south on Highway 185 through Beaufort. It takes about 66 minutes one way, which is why a planned visit suits us better than a rushed one.

1. Call (209) 563-1270 first. We confirm whether we can schedule your address, and when.
2. Book seasonal work early: fall for the furnace, spring for the AC.
3. Have the model number from the data plate ready, because a missed part here means a full day lost.
4. On arrival we test first and quote the work before we start.

If you need heat tonight, we may not be your fastest option, and we will tell you so on the phone.

Franklin and Crawford counties and a city electric system

Sullivan is unusual in three ways that affect your system. The first is the county line, since permit questions outside the limits go to Franklin or Crawford County depending on the address.

The second is power. The City of Sullivan provides its own electric distribution, so in-town customers should not assume an Ameren program covers them. Read your bill before you price a heat pump around a rebate.

The third is the country around town. Plan the system around your own fuel, because homes in the hills past the city limits can differ from in-town houses. Propane, a rural cooperative or an all-electric setup are all possibilities, and each one changes the replacement options.

Route 66, the Meramec and local landmarks

Sullivan grew up on the railroad and on lead, iron, zinc and copper mining, then on Route 66. The old Shamrock Motor Court, built around 1947 in native stone, still marks the west end of town. Meramec State Park lies just to the east, and Meramec Caverns uses a Sullivan mailing address, so a rural box here can be well out from town. Tell us the nearest crossroad.

We have no Sullivan jobs to show and no reviews from town. What is true is the distance, our Hermann office and our 1998 start. Ask Sullivan City Hall about permits inside the limits.

Heating and cooling in Sullivan worth planning ahead

• Furnace maintenance: a fall appointment avoids the January call that we may not reach in time, and it suits a 51 mile drive far better than a cold-night rush.
• AC maintenance: book before the first hot stretch, because humidity works an AC harder.
• Propane furnace service: hill-country homes past the mains need regulator and venting checks. Tell us which county your tank sits in, since the line runs right through town.
• Ductless mini splits: planned installs for additions and outbuildings, where one set scope and one date make the trip from Hermann worthwhile. See mini split vs central air.
• Furnace replacement: scheduled work that does not depend on a fast arrival. Book the changeover for a mild week, so the house is never at risk while the old unit comes out.
• Heat pump installation: the city runs its own electric distribution, so check your rate and any city program before comparing a heat pump with gas or propane.
