TNS Mechanical Services, LLC at 4840 Matlock Road, Arlington, Texas.

I had my house built, including a brand new Lennox unit. In the second summer, my A/C quit blowing cold air. After my home-builder let me know it was out of his hands, but Lennox has a warranty, I called TNS, told Todd what was going on. He showed up that afternoon, spent about an hour on the unit and diagnosed the coil was bad and needed to be replaced. He ordered the part, handled the warranty, and the price was MUCH less than what I had expected based on researching online and what my home-builder had told me to expect. The people at TNS are very friendly and seem to be very honest and fair. I have recommended them to several friends and family members and would recommend giving them a call.
