What is considered mechanical issues in a home?

Problems found in the foundation of the house or in the underlying structure of the house are considered structural defects. Mechanical defects are problems related to broken components in the house. Defects can occur in many different ways, depending on the components or systems in your home that are affected. The most common problems tend to occur with water intrusion due to faulty windows or doors (or perhaps a structural problem), cracks in foundations or exterior facades, defects in pipes, and problems with roofs and balconies.

Mechanical and electrical defects can cause very serious problems in the home, as well as the potential for safety hazards. Examples of poor maintenance include cracked or peeling paint, crumbling masonry, broken fittings, or poor quality cables or pipes. You can easily repaint a wall, replace an accessory, or repair a brick wall, but improvised electrical or plumbing situations are serious and potentially dangerous problems. Replace any of these cables or pipes.

Air conditioning systems have two fans. The indoor fan blows cold air over the evaporator coils and into the house's air ducts. The fan in the outdoor unit cools the condenser coil to prevent it from overheating. A faulty motor in any of those fans needs an air conditioner repair.

According to the Department of Energy, fast cycles and an oversized air conditioner are common causes of fan motor problems.
