Preventative Maintenance is Crucial to Keeping a Commercial HVAC System Running Smoothly!
Having your commercial HVAC system professionally serviced on a regular basis can help improve its function and extend its lifespan, while allowing you to realize significant cost savings thanks to the resulting more efficient workings of the system. At a minimum, you should have preventative maintenance performed on your business’ HVAC system at least once a year, though scheduling maintenance twice annually–typically when the weather changes from cold to hot and back again–can help ensure that your system stays in top working order. Here’s what your HVAC technician should be doing in each season maintenance visit.
Spring or Summer Commercial Air Conditioner Maintenance Checklist
Getting professional preventative maintenance performed on your system before warm weather fully hits can help ensure that you have air conditioned air when you need it most. In your spring or early summer maintenance visit, your HVAC technician will:
- Replace any clogged filters on the cooling equipment;
- Inspect the condition of pulleys and belts, replacing if necessary;
- Clean the evaporator coils and condenser;
- Check the refrigerant levels, adding refrigerant and examining for leaks if the levels are low;
- Clean out drain lines;
- Check any electrical connections;
- Examine the operating condition of the blower motor and fan, performing adjustments and replacements as needed;
- Ensure that the motors, bearings and any other moving parts are adequately lubricated;
- Confirm that the thermostat is working properly; and
- Confirm that there’s adequate air flow through all ducts.
Fall or Winter Commercial HVAC System Maintenance Checklist
When entering fall, the major purpose of preventative HVAC maintenance is to ensure that all components that contribute to its heating function are in good shape and not in need of repair or replacement. Your HVAC maintenance technician will:
- Replace any clogged filters on the heating equipment;
- Inspect the condition of pulleys and belts, replacing if necessary;
- Check the strength of all electrical connections;
- Clean out any drain lines;
- Examine the operating condition of the blower motor and fan, performing adjustments and replacements as needed;
- Check the condition of the burner assembly and ignition;
- Ensure that the motors, bearings and any other moving parts are adequately lubricated;
- Confirm that the thermostat is working properly; and
- Examine the heat exchanger.
What are the Most Common Commercial HVAC System Issues that Require Repair?
Unfortunately, there’s likely to come a time when you’ll face issues with your commercial HVAC system that require a professional repair. The following are the five most common problems that can arise with your HVAC system, requiring a call to your service technician.
A Lack of Regular Preventative Maintenance
Failing to have regular preventative maintenance performed on your commercial HVAC systems can often give rise to bigger issues. Problems that would have been caught during a maintenance visit are allowed to worsen, resulting in the need for extensive–and potentially major–repairs.
Refrigerant Leaks
Your HVAC system’s refrigerant is a key component in its cooling function, allowing the unit to cool and dehumidify air. Any refrigerant leaks in your HVAC system can result in too little refrigerant to properly cool the air, necessitating that the leak be repaired and additional refrigerant added.
Unbalanced Air Flow
Ideally, hot or cold air will be pushed by your HVAC system through all vents in your building at equal rates. Sometimes, however, some rooms end up receiving too much or too little heated or cooled air. To fix this problem, your HVAC service technician will likely need to balance the dampers that help control air flow throughout the system.
Malfunctioning Thermostats
It’s not always the HVAC system itself that causes problem requiring professional help. Your thermostat communicates with the HVAC system, regulating the system’s timing and the amount of cold or hot air produced. When a thermostat starts to malfunction, it can send incorrect signals to the system, resulting in poor performance–and necessitating a visit from a professional repair person.
Clogged Filters
Filters help keep allergens, dust and other pollutants from circulating around your indoor spaces, but these filters will slowly become clogged as you use your system. Dirty filters mean that both your heating and cooling systems must work harder to warm or cool the air, resulting in higher energy costs and lower system lifespans. Having a professional change out your filters periodically is one of the most important–and most commonly needed–repairs.
