Words can’t express how thankful I am for St Louis Heating and Cooling. I was out of town visiting family when my house alarm notified me by text message that the temperature in my house had fallen below 50 degrees! Back home in STL, temperatures were close to 20 degrees and weren’t supposed to go up any time soon. I called a friend to let ETL-HVAC inside to check the furnace and sure enough, it had to be replaced. They were able to replace it rather fast and got my house temperature back up before the pipes could freeze!!! I would recommend these guys to anybody that needs a furnace repaired in Saint Louis!
