 Trustindex verifies that the original source of the review is Google. When our home A/C unit stopped blowing cool air during a weekend emergency—with no frozen condenser coils and a warm suction line—contacting DFH Heating and Cooling was the best decision we could have made. Our technician, Ralph, was friendly, personable, knowledgeable, and skilled. He arrived at our house within 30 minutes of our call, quickly resolved the issue, and patiently answered all of my questions regarding causation and future maintenance. If you are dealing with unexpected HVAC trouble, I highly recommend calling DFH Heating and Cooling.

 Trustindex verifies that the original source of the review is Google. Wonderful service.  I have used them for replacing the furnace and now the air conditioning unit.  Polite, professional, personable, nice to my dogs, closed the fence before they left.  I would recommend to anyone who needs HVAC services.

 Trustindex verifies that the original source of the review is Google. Called DFH Company originally diagnose a leak. They determined an evaporator coil needed replacement and provided a replacement estimate at what I thought was a fair price. Since the system was quite old, we then started collecting quotes. DFH's estimate was similar to other companies but offered a Trane system whereas Goodman was what the others were offering. We went forward with DFH's estimate. They came out in a few days and installed a new Trane system in one day. There was a manufacturing defect in one of the parts right out of the box, but after notifying DFH, they arrived the next day to replace it and address the issue quickly. Will recommend DFH to anyone who has property in Louisville.

 Trustindex verifies that the original source of the review is Google. Outstanding company! My 30 year old system finally bit the dust, so I called DFH to come take a look. They showed up the same day to evaluate the old system, and one day later my new Trane furnace is installed and running! They don’t look to upsell you or nickel and dime you, they just do what needs to be done, quickly, and for a fair (great!) price. I love that they are locally owned too.  Will definitely use DFH going forward.
