Minor repairs are small jobs that can be done with minimal knowledge and basic tools. Examples of minor repairs include plumbing issues, replacing light fixtures, changing worn floors, or replacing heating filters. Additionally, an auxiliary heat exchanger coil or the evaporator and condenser coils are types of heat exchangers. An auxiliary heat exchanger is a secondary or extra heat exchanger in the system, usually seen in heat pumps and large systems that cool large spaces. The difference between major and minor alterations and repairs can be confusing due to outdated rules and guidance material.
However, minor repairs are jobs that can often be done at home with a minimum of knowledge and basic tools that any homeowner is likely to have on hand.
