DeHart Air Conditioning, technician installing air conditioning in a client house, OK

Your air conditioner is supposed to keep you cool and comfortable, but over time it can decrease in efficiency or stop working completely. This not only makes you uncomfortable but also leaves you with high energy bills. Avoid being without air conditioning and have your system replaced by the experts at DeHart Air Conditioning.

AC Installation in Duncan & Chickasha, OK

Most air conditioning systems last around a decade or so when they’re well maintained, so if your AC is reaching this point, it’s best to start thinking about replacement before it breaks down entirely. At DeHart, we can replace your air conditioner for a similar unit from Lennox, although we always recommend choosing the highest efficiency equipment available.

In addition to installing central air conditioning systems, we also specialize in ductless mini-split installation, heat pumps, and the most sustainable option of all — geothermal systems.
