"Alex HVAC has been a huge blessing. I had my water heater stop working two days before Christmas eve and Alex sent out his technicians the very next day to change out my water heater. Miguel, Alex and his other technicians were professional and polite. I will recommend them to anyone and everyone. Once again thank you Alex"
