What Happens During a Preventive Hvac Maintenance Inspection?

July 20, 2023


Maintenance is an important aspect of owning a heating and cooling system. Over time, dust and worn parts lower the efficiency of your HVAC system and increase the risk of problems. Scheduling regular preventive maintenance for your furnace and air conditioner can improve the lifetime of these units by up to 48% and prevent yearly losses of up to 15% in heating and cooling efficiency.

Heating Maintenance

Just before or during heating system, a heating maintenance check includes an inspection and testing of your furnace or boiler. During this visit, your HVAC technician will check and replace your furnace filter if necessary. He will inspect your heater’s exterior and ventilation system for signs of wear and perform any necessary repairs. Next, the interior components of your furnace will be cleaned and inspected for signs of wear or damage. This includes the ignition assembly, blower, motors, and pressure switches. The power consumed by your furnace and its electrical components will be measured to check for unnecessary power usage. Your home’s thermostat will also be checked, cleaned, and calibrated. The furnace will be turned on and monitored during function to ensure each component is performing properly. Additionally, your HVAC technician will test for carbon monoxide leaks and ensure all ventilation and piping is clean. If you have a boiler, the controls, safeties, pump, low water cutoff, and sight glass will be checked.

Cooling Maintenance

A maintenance check before or during cooling season consists of a thorough examination of your home’s air conditioner to ensure it is in top condition. Your technician will check both the indoor and outdoor components of your air conditioner, including all internal parts, motors, and belts. The air conditioner’s coolant levels will be measured and lost coolant replaced if necessary. Your technician will check the circuits, safety controls, drain line, condensate pump, and all caps and valves as well. Electrical components will be inspected for signs of wear or damage and replaced to prevent sparking or failure. He will check that your outdoor unit is level for optimum performance. If needed, he will also replace your home’s HVAC filter to prevent dust and debris from entering your air conditioner or ductwork. Your thermostat will be inspected and cleaned or calibrated if necessary for more efficient cooling.
