Is New California part of Plain City?

No. New California is its own community in Jerome Township, Union County. Its mail comes through the Plain City post office, so many addresses read "Plain City, OH 43064." We serve both.

My house in New California was built in the 2000s. Should I replace my furnace and AC now?

Not always. If they run well, a tune-up may keep them going. If you're facing a big repair, or your AC uses R-22, we'll show you repair and replacement prices side by side.

Can you fix my heat pump?

Yes. We repair and replace heat pumps and their backup heat strips, and can set your thermostat so backup heat doesn't run more than it should.

Why is one room over my garage always too hot or too cold?

Bonus rooms sit over unheated space at the end of a long duct run. Fixes range from balancing the ducts to a ductless mini-split for that room.

What should I do if I smell gas or my CO alarm goes off?

Leave the house and call 911 or your gas company from outside. Once it's safe, call us to find the cause.

Heating & Air Conditioning in New California, OH

Your New California Heating and Cooling Team

New California is the crossroads community at U.S. 42 and Industrial Parkway, in the middle of Jerome Township, Union County, just south of the U.S. 33 interchange. It was platted in 1853, and local tradition says the name came from news of a man passing through on his way to California. Near the crossroads stands the Jerome Township Soldiers' Monument, a zinc shaft more than 21 feet tall, dedicated on Memorial Day 1913 to the township's Union soldiers. Mail here comes through Plain City under ZIP 43064.

Jerome Township's population more than doubled between 2000 and 2020, from 3,950 to 9,504, as new neighborhoods filled in. One Hour Heating & Air Conditioning® of Delaware repairs and replaces furnaces, heat pumps and AC systems throughout New California and Jerome Township.

Heating and Cooling Homes in New California

Homes here are young. Census estimates show the median home in New California was built in 2008. About 41% went up in the 2010s, and another 32% in the 2000s. Across all of Jerome Township, more than half the homes have been built since 2010.

So whole streets got their systems at about the same time, and those systems are aging together. A furnace or AC from the 2000s is now past 15 years, when breakdowns pick up and replacement starts to make sense. Early-2010s heat pumps and air conditioners are past 10 years, when compressors and fan motors start to wear.

Most New California homes heat with natural gas, about three in four. Close to one in five uses electricity, and a small share use propane. Township-wide, electric heat climbs to more than a quarter of homes. We service all of them.

New California Local Insight

About a third of New California homes went up in the 2000s, and many still have their first air conditioner. Read the label on the outdoor unit. Many systems installed before 2010 run on R-22 refrigerant, which hasn't been made or imported in the U.S. since 2020, so supplies keep shrinking. When one of these units leaks, replacing it often makes more sense than recharging it. We'll price both so you can decide.

Seasonal HVAC Tips for New California

In early fall, get your furnace or heat pump checked. Swap filters often in a newer home, where construction dust clogs them fast. When it snows, keep drifts off the heat pump and the furnace's outdoor pipes. Keep winter humidity around 30 to 40% to protect wood floors. In spring, have your AC checked and clean grass clippings off the outdoor coil.

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!!!

Glenn was very impressive. He was here for over 5 hours working very hard to find a solution. He also was very honest with me about the issues to our units and I appreciated that a lot. 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.
