I broke the thermostat on a 2 month old NewAir G56 heater and needed a replacement. Contacted Customer Service and ended up dealing with Seymone. She was very easy to deal with and was more than happy to help me with the replacement. Communication was excellent and the transaction went smoothly. The heater itself is the best I've ever purchased. Heats my 20' x 23' garage from bone chilling cold to short sleeve shirt comfort in about 35 minutes, With great products and super customer service I will definitely do business with NewAir again!!
