I am not typically a person to leave a comment as I find them to be a bit ridiculous, but this company and their service is the absolute worst. I closed in a new build home and have had 7 visits from D&L over the course of 8 weeks because of their poor planning, lack of professionalism and scheduling efficiency, and horrible product service and repair. As I am writing this comment the heat index is 85 degrees and it is 85 degrees in my brand new home.
Every time I call they have a 4 day turn around on getting out to service their garbage product(s). I have a warranty through the builder on all products and service and still would consider paying out of pocket to get a new provider. I cannot stress enough how terrible this company is.

This company is about as sorry as it gets. We bought a brand new home in a new subdivision and were told by our contractor that we have a five year warranty with this company on the air conditioning and heating unit. Four years later and we are experiencing problems with the unit so I gave them a call and was told "sorry we are only honoring our first year customers because we are to busy" and was hung up on. So anyone who has bought a house with an air unit from this company BEWARE they wont honor their warranty and do not care about their customers.

The worst customer service ever. If I could give 0 stars I would. This company has been to my home 4 times and still has not fixed the problem. I called them again today and they gave me the run around and said it's out of warranty any way which was not a problem because even though they didn't fix the problem the first 4 times I was gonna pay them but the lack of care and lack of organization was ridiculous. Do not waste your time and money with these people!
