 "My wife and I needed a new furnace and our entire duct work needed to be replaced.
We had estimates from a total of 3 companies. Out of the 3, Dillegence gave the most competative quote. They were also the most thorough during the estimate process.
We now have a comfortable home. We are 100% satisfied.( 100% recommended.)"

Project: Repair or Service a Central Air Conditioning System
"I got stiffed twice by a friend of a friend who did A/C work aside from the company he worked for. He did not diagnose my problem during two visits and just added refrigerant and stop leak...lasted seven weeks. Found Dilligence in the phone book, read reviews and hired them. They found the leak, flushed my a/c system and replaced potentially damaged parts from the stop leak; all within a 24 hour period. Mr. Dill was easy to reach and very knowledgeable. My Technician, Mr. Gomez, was very friendly, personable and an extremely hard worker. I highly recommend this company."

Project: Install a Central Air Conditioning System
"Of the 3 companies from whom I received estimates, I chose Dilligence to replace my central air for their (1) reputation (friends here in Winston had Dilligence install a complete HVAC system in their Ardmore home last Fall), (2) very fair pricing, and (3) their creativity in the installation design of the new Bryant system. As for the actual work, it was done in less than a day by two extremely professional installation specialists. The system is working great and I couldn't be more pleased with the entire process. Most of all, the Dilligence staff are people you can trust and don't mind having in your home."
