Included in an HVAC system installation may include surveying/inspecting the current system and set up, taking measurements to ensure a new system is the proper size and capacity for the home; carefully de-installing the existing system, being careful to minimize the disturbance of comfort for the occupants of the home or office; connecting the new units, which can involve installing ductwork, wiring, tubing, pipes, or electrical supply lines; and a final check after installation to ensure the job is completed and the system is safe and ready for the homeowners to use.
Inspection and maintenance services focus on things like checking pipes and tube joints for leakage, testing thermostats, checking and refilling refrigerant levels, testing electric circuits, inspecting fans and motors, troubleshooting various components for optimal efficiency or faults, or changing HVAC air filters.
The next step up from maintenance is the actual repair work necessary when problems are discovered. This portion of the job requires installing/repairing/replacing specific faulty parts on a heating or cooling system to get the heat or air conditioning running again. This is where a majority of attention is focused in the average HVAC contractor, as repairs are often on an emergency basis, particularly in the cold of winter or extreme heat of summer.
