So why is preventative maintenance important?

Making sure your HVAC system is working properly at all times can not only make sure your building is staying at the right temperature, it also keeps your costs down on bills.

Not having a preventative maintenance plan in place can cost your company thousands of dollars in repairs if the worst case happens.

Now you may be wondering what all is involved in a PM Plan, below we have created a checklist these services should be performed in the spring for cooling systems, the fall for heating systems.

This is a service which should be performed by a commercial HVAC technician. Preventative maintenance serves as a tune-up for your building’s HVAC systems, helping them run more efficiently throughout the season. Several steps will be taken to correct existing issues and prevent future performance problems and breakdowns – these steps generally include the following.

For outdoor components:

• Coil and cabinet are inspected and cleaned
• Drain pans and condensate lines are cleared of obstructions
• Compressor is inspected
• Fan motor and blades are inspected and lubricated
• Control box, switches, wiring, and safety controls are inspected
• Refrigerant level is measured and recharged if necessary

For indoor components:

• Blower assembly is checked and cleaned
• Belts are lubricated or replaced
• Combustion blower housing is cleaned
• Evaporator coil, drip pan, and condensate lines are cleaned and cleared
• Burner assembly is inspected and cleaned
• Ignition system is cleaned
• Safety controls are tested
• Heat exchanger is inspected
• Flue system is checked for dislocations and wear
• Control box, wiring, and connections are checked and tightened
• Air filter is replaced or cleaned
• Duct system is checked
• Check and Change Air Filters

Air filters should be inspected every three to four weeks to ensure the filter has not become clogged with debris.

Changing of air filters should be performed every three months, per the manufacturer’s recommendation or as needed.

Maintenance staff should stay on top of air filter checks and changes, as restricted airflow through the HVAC systems hinders performance and increases energy consumption by this equipment. During periods of heavy use, you may find it necessary to replace filters more frequently.

Running your commercial HVAC systems with clean air filters can lower energy consumption by up to 15%.

Program Thermostats:

Have these performed at the beginning of heating season and cooling season, and when temperatures hit the point of not using the systems regularly.

When it’s time to switch from one HVAC system to the next, or it’s time to not run it so frequently, it’s time to check the programming on your building’s thermostats to ensure settings are optimal for energy savings. We do this by manually programming your thermostats or through your building automation system; even if you’ve had programmed heating and cooling schedules in the past, it’s still smart to recheck to make sure they still fit your needs and the same areas are still in regular use.

Periodic System Checks:

Have these performed, or as needed.

Check thermostat operation. If your thermostats are not operating correctly throughout the season, your HVAC systems could be running more frequently than necessary, boosting your energy consumption. If thermostats are not working properly, have them repaired or replaced.

Have your technician check drip pan and drain lines. Clogs in your HVAC systems’ drainage lines can cause moisture to back up into your building, causing mold and mildew growth as well as the potential for damage. Make sure the drip pan and drain lines are emptying correctly and remove any obstructions that develop. Having your system fail in the middle of summer can have serious consequences.
