My service tech told me that higher efficiency products break down more frequently. Is this true? Back
Possibly. However, ask your installer if his automobile has power steering, power brakes and power windows, and even an electronic air conditioning system. These are just more things to go wrong but we all want the convenience and comfort they provide.
Quality control has improved warranties dramatically in the last ten years through the use of manufacturing process certifications and increasingly efficiency assembly methods. Product innovations in efficiency and function will increase complexity slightly but the return in comfort and energy savings will more than offset any potentially slight increase in maintenance.
Base your decision on features, initial cost, ownership costs including energy usage, and comfort.
