"I have a number of rental properties and flip a few houses so I need HVAC help frequently. I can attest, from multiple experiences, DND is hands-down the most reliable heat and air company I have done business with. And having purchased my first rental house in 1970 I have dealt with more than a few HVAC people. 

I could give several examples of DND's reliability and how Danny has gone way beyond the call of duty several times (tenants tend to get a little upset when it's 25 degrees and the heat goes out). 

I could also relate how I called DND with an AC problem on the upstairs unit at my own house at 4PM on a Friday when we had just welcomed weekend guests.  DND arrived within 30 minutes to save the day. Their service is second to none.

And did I mention DND's pricing is very competitive? 

I'll never use any other HVAC company."
