On 06 January 2016, I had two TLC teams working at my home. The first team came to install a newer, bigger humidifier to my gas furnace. The second team arrived about 1.5 hours later to clean my heat ducts which were still full of dry wall dust from my home having been built a couple of years ago. Both teams arrived exactly when they were supposed to, and the work took no longer than anticipated. Each team worked efficiently and as rapidly as they could without allowing professionalism to suffer. Upon completion of the work, the teams cleaned up after themselves and probably even left the work area cleaner than it was when they arrived. My wife and I were very impressed; we now have a yearly contract with TLC to do our heating and air conditioning maintenance on a routine basis.
