I was very impressed with Servaplus. Their technician was courteous and knowledgeable and had my problem (a faulty circuit board) diagnosed and repaired in about twenty minutes. Their trucks carry a good supply of parts, and I really appreciate the security of knowing their labour is guaranteed for a full year (the guarantee for the manufacturer's part will vary - my Whirlpool circuit board was only guaranteed three months). My only small quibble is that they are too popular and I had to wait two days for my appointment!
