I just wanted to write something real quick in regards to the awesome service from St Louis Heating and Cooling. My A/C unit died around 9 pm last summer on one of STL’s hottest and muggiest nights. Within just a few hours, our house was unbearable and waiting till morning wasn’t an option with my children and pets in the house. I called ETL-HVAC around midnight and they came out promptly and got my AC unit running again. Thank you so much!
