Do you serve both the Madison County and Union County parts of Plain City?

Yes. We serve the whole village, plus the nearby parts of Darby and Jerome townships and the rest of the 43064 ZIP code.

My Plain City home was built in the last few years. Does it still need a tune-up?

Yes. Yearly service keeps a new system running as designed, and it's the best time to catch install issues like low refrigerant or poor airflow before they become repairs.

Do you work on propane and all-electric homes outside the village?

Yes. Many homes in the rural parts of 43064 heat with propane or electricity. We repair, maintain and replace both.

What should I do if I smell gas?

Leave the house and call 911 or your gas company from outside. After it's declared safe, we can find and repair the cause.

Heating & Air Conditioning in Plain City, OH

Your Plain City Heating and Cooling Team

Plain City sits where U.S. 42 meets State Route 161, with Big Darby Creek winding right through the village. It's also split between two counties. Part of town is in Darby Township, Madison County, and part is in Jerome Township, Union County. Isaac Bigelow laid it out as Westminster in 1818. It was called Pleasant Valley for a time and became Plain City in 1851.

One Hour Heating & Air Conditioning® of Delaware works on both sides of the county line. We fix, maintain and install furnaces, heat pumps and central air, from the older houses near the town clock to the new streets at the edge of the village.

Our promise: Always On Time…Or You Don't Pay A Dime!® If we don't arrive in the window you pick, the service call is free.

Heating and Cooling Homes in Plain City

Plain City has two kinds of homes, and each needs a different kind of care. Census estimates put about 23% of village homes before 1940. Another 41% went up between 1990 and 2009, and close to one in five has been built since 2010, with new neighborhoods still filling in.

Many 1990s and 2000s homes still run their original furnace and AC, or a first replacement. Equipment that age needs more repairs, so plan a replacement before it quits on a freezing night. Older homes near downtown often have ducts that were added later and upstairs rooms that run hot.

Fuel varies across the area. Inside the village, about nine in ten homes heat with natural gas, which Columbia Gas of Ohio delivers here. Across the wider 43064 ZIP code, about half of homes use natural gas, more than a quarter use electric heat and about one in six burns propane. We work on all three, including heat pumps.

Plain City Local Insight

Plain City is building fast. The village planner called 2023 a record-breaking year for development, and Darby Station alone was planned for more than 400 single-family homes. If you just moved into a new build, book a tune-up in your first year. We check refrigerant charge, airflow and thermostat setup, and catch installation problems while they're small. New homes are sealed tight, and a whole-home humidifier makes dry winter air much easier to live with. In older homes downtown, ask about adding a ductless mini-split to the rooms your ducts never quite reach.

Seasonal HVAC Tips for Plain City

Have the furnace serviced in September or October, ahead of the first hard frost. Check your filter monthly during heavy use. After snow, clear the heat pump and the plastic furnace pipes outside. Aim for about 30 to 40% indoor humidity. Get the AC checked in spring, so it's ready by the time the Miami Valley Steam Threshers show fills Pastime Park in July.

Very pleased with this company and our technician, Joshua. Scheduling was efficient and fast, they came out the same afternoon that I called. After I had another company come out that morning and tell us they could not fix my furnace dehumidifier, Joshua had it fixed in a short time after his arrival. Pricing was very fair. This is my new HVAC provider!

Andrew was excellent in his detailed review in quoting out a new heating/AC system for our home. He asked what I was looking for and we went room by room reviewing what was in each room. He confirmed that the current layout was very good and the system we had was the correct in its ratings. He prepared our quote as I had asked, no pressure with any additional ons or upsells as I was clear in what we were looking to do. He went over the quote with me line by line asking if I had any questions. Andrew was very polite and professional throughout the whole process. Can’t say enough good things about the dealings I have had with these two gentlemen along with the young lady I talked to on the phone. If you’re on the fence- call these guys.

"Great experience with One Hour Air! They showed up right on time, replaced my thermostat, and did a thorough AC maintenance check. Their pricing was very affordable and honest and their technician James was extremely knowledgeable. He explained everything he was doing and made me feel completely comfortable. He broke everything down clearly and never talked down to me or made me feel stupid. Highly recommend!!!

DeAndre Yarbrough, the service tech was knowledgeable, clear and concise in his explanations, honest about priorities (mega kudos on that front), pleasant and friendly in his demeanor. I, literally, have zero complaints. He was absolutely great. I felt very comfortable with his explanations and service on my system.
