About DFH Company

The DFH Company has been serving Greater Louisville residents’ heating and cooling needs since 1935. Don Hinkebein opened a small heating and air conditioning business on the corner of Shelby St. and Broadway in downtown Louisville, Kentucky. With the help of his sons, the business grew.

In 1969, Don Hinkebein Jr. incorporated the DFH Company. Today, the company still has strong family roots with Don’s sons Chris and Alex assisting in continuing the business.

DFH Is Green!

Unbeatable comfort, unmatched quality

For the top of the line in cool comfort, look no further than the XL20i. It’s among the industry’s most efficient air conditioners available. What does that mean for you and your family? It means you’ll enjoy total comfort on the hottest days of the year and lower your cooling costs at the same time.

Trane XL20i features

When matched with a variable speed indoor unit from Trane, the XL20i has another special feature. It’s a method of enhancing airflow that we call Comfort-R™ and it gives you greater humidity control in cooling. This is accomplished by running the fan at a slower speed during start-up. Comfort-R™ also provides warmer air during heating start-up. These managed cycles reduce temperature variances for the optimum in home comfort.

Efficient performance

The XL20i’s SEER (Seasonal Energy Efficiency Ratio) rating of up to 20.00 is among the highest energy efficiency rating of any air conditioner available today. The XL20i has two compressors: one for milder weather and a second larger compressor for those extremely hot days. It’s like having two units in one.

ComfortLink II communicating capability

ComfortLink II communicating technology (available when matched with communicating indoor units) connects all of your key components so your system automatically charges, configures and calibrates for optimal performance and efficiency through the lifetime of your products. When the optional Telephone Access Module (TAM) is added, you can conveniently adjust settings and receive system updates wherever you are by phone.

Economical operation

Increased efficiency may substantially lower your home cooling costs.

Quiet comfort

Multi-stage fan motor adjusts speed to quietly provide maximum comfort.

Durable construction

Materials for all components are tested again and again for long-lasting performance and durability.
