Specific Components Maintenance 

Actual maintenance plan may vary from installation to installation, yet there are several key components from 
maintenance prospective. 

If needed, contact respective component manufacturer for additional maintenance information. 

 
Filters 

 

Ensure air filters are clean. Dirty air filters will negatively affect HVAC system performance and lifetime 

 

Frequency of filters replacement will vary based on air quality, HVAC system usage, facility type, etc. Make 
sure to replace filters regularly 

 

Replace with filters of equivalent size and rating 

 refer to HVAC system details (compartment stickers, etc.)  

 
 

Insulation 

Inspect  HVAC  system  insulation,  exposed  to  airstream  for  microbial  growth  (i.e.,  mold).  If  there  is  evidence  of 
microbial growth on the interior insulation, the insulation should be removed and replaced prior to operating the 
HVAC system. 

 

Air-Side Coils  

 

Warning: Hazardous chemicals!

 Cleaning agents can be highly acidic or alkaline. Handle all chemicals carefully 

and use appropriate personal protective equipment (PPE). Refer to the cleaning agent manufacturer's Materials 
Safety Data Sheet (MSDS) for safety and handling information. Failure to follow all safety instructions could 
result in serious injury or death. 

 

Warning: Hazardous pressures!

 Coils containing refrigerant under pressure must not be cleaned using a 

solution over 150 ºF. Failure to follow these safety precautions could result in coil bursting, which could result 
in serious injury or death. 
 

To clean the coil 

 

Disconnect all electrical power to the equipment 

 

Use a soft brush to remove loose debris from the coil 

 

Mix a high-quality coil cleaning detergent with water according to the manufacturer's instructions 

 

Clean coil according to detergent instructions 

 

Thoroughly rinse both sides of the coil and the drain pan with, clean water 

 

Straighten any coil fins that have been bent during the cleaning process 

 

Confirm the drain line is clear 

 

Replace all panels and parts and restore electrical power to the equipment
