I have been a satisfied customer of Dwyer for over 30 years. But, I have just had the company now replace the SECOND heat pump blower in just a period of 4 years. Dwyer says parts are NOT GOOD like in past years, warranties therefore not good. Thr Dwyer technicians are all good, capable people, but the company needs to put pressure on their manufacturers for better products or find new manufacturers with better products they can guarantee and warrant.
