The absolute worst time a heater can die is on the coldest day in Austin's recorded history. The snow drift in my front yard is over 2 feet tall, the roads are crazy and my heater dies at 2 am when it is 8 degrees outside. Thankfully Evenaire was able to save me. I made a call early in the morning and left a message, got a call as soon as they were open explaining that their crew couldn't get out yet because of the road but they would text me as soon as it was safe for their people. I was expecting not to get any help today, because crazy weather. Around 2pm (when the roads started melting) I get a text letting me know a technician is heading my way. The temp in my house was falling fast. My heatpump is about 10 years old and needed life support. A quick diagnostic, a wave of a magic wand (because I have no idea what sorcery runs a heater) and voila, my heater was working again. I was ready to sell my soul and my firstborn child for heat, and when it came time to pay I was shocked at how little the charge was. The heat is on, I still have my soul and my firstborn. I can't recommend this company highly enough.
