WHAT HAPPENS DURING A PREVENTIVE HVAC MAINTENANCE INSPECTION?
-
An HVAC maintenance check gives your heating and cooling system a professional inspection, cleaning, and performance test before peak heating or cooling season. During the visit, a trained HVAC technician checks airflow, filters, electrical components, thermostat operation, refrigerant levels, safety controls, drain lines, motors, belts, coils, burners, and ventilation.
For Columbus homeowners, regular HVAC maintenance helps catch small issues early, improve comfort, protect system efficiency, and reduce the risk of surprise breakdowns during Ohio’s hottest and coldest months.
HEATING MAINTENANCE
Just before or during the heating season, 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. Your technician turns on the furnace and monitors a full heating cycle. This allows them to confirm that each component starts, runs, and shuts down 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
The lifespan of a central HVAC system is about 15-20 years. A maintenance check can help you maintain efficiency, and before or during the cooling season, it 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 will be replaced if necessary. Your technician will check the circuits, safety controls, drain line, condensate pump, and all caps and valves as well.
Your technician inspects electrical components for wear, corrosion, or damage. If a part creates a safety or reliability concern, the technician can recommend replacement before it sparks, fails, or causes system damage.
Your thermostat will be inspected and cleaned or calibrated if necessary for more efficient cooling.
What Is Included in an HVAC Maintenance Check?
A professional HVAC maintenance check usually includes both a visual inspection and hands-on system testing. Your technician looks for worn parts, safety concerns, airflow restrictions, dirty components, drainage problems, and signs that the system may need repair.
Common HVAC inspection steps include:
Check and replace the air filter if needed
A clean filter helps protect airflow and keeps dust from building up inside the system.Inspect the thermostat
