Does your service area include Unionville Center and Darby Township?

Yes. The village, the rest of ZIP 43077 and the farms throughout Darby Township are all covered. Pick your arrival window when you call or book online.

Can you service a propane furnace?

Yes. Propane heats more homes in and around Unionville Center than any other fuel. We repair, tune up and replace propane furnaces from all major brands.

My farmhouse dates to the 1800s and has no ducts upstairs. What can I do?

A ductless mini-split is often the easiest fix. It needs only a small hole through the wall, so there's no need to open up plaster or floors. We'll look at the house and give you options.

What should I do if I smell gas?

Leave the house and call 911 or your gas company from outside. For a propane home, the gas company is your propane supplier. When it's safe to go back in, call us and we'll find the cause.

Heating & Air Conditioning in Unionville Center, OH

Your Unionville Center Heating and Cooling Team

Unionville Center is a small village in Darby Township, southern Union County, home to 241 people at the 2020 census. The county surveyor platted it as Unionville in 1847, with 15 lots and two streets. Ohio already had a Unionville, so "Center" was added when the town got its post office. Because it sat on the railroad, people also called it Unionville Station. Charles Warren Fairbanks, who went on to serve as the nation's 26th vice president, was born near the village in 1852. The Fairbanks Festival each May and the Fairbanks Local Schools both carry his name.

One Hour Heating & Air Conditioning® of Delaware keeps heat and cooling running in village homes and on the surrounding farms. Homes out here usually run on propane or electricity, and we're set up for both.

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 Unionville Center

The village is old. Census estimates are rough for a place this small, but close to half of village homes date from before 1940, decades ahead of central air. In houses like these, ductwork was often added later, and upstairs rooms can be hard to heat and harder to cool. Out in Darby Township the mix is wider: about a quarter of homes predate 1940, while another quarter went up in the 2010s.

Natural gas is rare here. Census estimates show no village homes on utility gas. About half heat with propane and about a third with electricity, and a few still use fuel oil or wood. Across Darby Township, propane leads, followed by electric heat, and about one home in ten still burns fuel oil. With propane or electric heat, efficiency shows up right on your bill, so tune-ups and sealed ducts pay off.

Unionville Center Local Insight

With so many homes on propane, an empty tank can leave you without heat on the coldest night of the year. Watch your gauge in long cold spells and schedule deliveries early. If the tank does run out, call your propane supplier first so they can check the system before anything is relit. Then call us if the furnace still won't start. To burn less propane, ask about dual fuel: a heat pump covers mild fall and spring days on electricity, and the furnace kicks in when it turns bitter cold.

Seasonal HVAC Tips for Unionville Center

Get the furnace serviced around the time Fall Fest comes to the village green. Top off your propane tank before winter sets in. Replace the filter every 1 to 3 months. After a snowstorm, dig out the heat pump and the furnace's exhaust and intake pipes. Keep indoor humidity near 30 to 40% so old woodwork doesn't dry out. Come spring, have the AC checked and rake leaves off the condenser.

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!!!
