Each season puts different demands on your commercial HVAC system. With that in mind, a thorough inspection should be performed and a maintenance routine developed as the weather changes. Just as you would check for snow obstructions, iced components, and other issues in the winter, action must be taken to ensure your system will perform consistently in spring. Here are six items to include on your checklist:
1. Review the thermostat settings
It’s important to verify that the thermostat is set up for the current weather conditions. In particular, you’ll want to make sure that it’s not cooling or heating the building more than necessary. You may also need to adjust fan speed and humidity levels.
2. Inspect the filters
Dirty filters restrict airflow and can cause your HVAC system to work harder than necessary, leading to increased energy costs and premature wear and tear on the equipment. It’s a good idea to check and replace filters every month or so, depending on your environment and filter type.
3. Clean the evaporator coils
These coils are responsible for absorbing heat from the air and transferring it to the refrigerant. If they become dirty, the coil’s effectiveness is reduced and your system will have to work harder to maintain the desired temperature. Coils can be cleaned with a special coil cleaner or a garden hose.
4. Inspect the condenser
The condenser is responsible for releasing heat from the refrigerant. If it becomes blocked or covered in debris, the system will not be able to cool properly. You can clean the condenser with a garden hose or pressure washer.
5. Check the refrigerant levels
If the refrigerant levels are low, your system may not be able to provide the cooling power you need. You can have a professional check and refill the refrigerant as necessary.
6. Tighten all connections
Loose connections can cause the system to work harder than necessary and lead to component failure. It’s a good idea to give all of the system’s connections a quick check and tighten them as needed.
By following this checklist, you can help ensure that your commercial HVAC system is ready for the demands of spring.
