HVAC is a massive portion of the energy bill for any commercial building. Learn about the different ways to increase safety and decrease the high costs associated with HVAC.

Our Checklist for Maintaining a High-Functioning HVAC System

If you oversee or own a commercial property, then you know full well the implications that HVAC maintenance can have on your bottom line. If not properly maintained, HVAC systems can run inefficiently, or be at risk of full mechanical breakdown. No one likes writing checks to HVAC companies and following a proper commercial HVAC checklist can save a TON of money and future headaches.

STEP 1: Preventative HVAC Maintenance

The first order of business is to perform preventative maintenance. Due to the current weather conditions, this maintenance will be done in the spring (for the cooling system) and in the fall (for the heating system).

The point of preventative maintenance is to stay ahead of any issues. For example, summer is hot, therefore the cooling systems should be checked and maintained before summer arrives. Vice versa for the winter.

PRO TIP: Hire an HVAC maintenance company that you trust to perform this maintenance. This is because they will be dealing with the mechanical intricacies of your systems and may have access to sensitive areas and information.

STEP 2: Create an Outdoor HVAC Inspection

  • Inspect and clean the coil and cabinet.
  • Clear the drain pans and condensate lines of any obstructions or debris.
  • Inspect the compressor to ensure it’s fully operational.
  • Lubricate the blades and the fan motor.
  • Inspect all switches, wiring, safety controls and the control box itself.
  • Ensure there is plenty of refrigerant; if not, top it off!

STEP 3: Complete an Indoor HVAC Inspection

  • Clean and inspect blower assembly.
  • Lubricate or replace belts.
  • Clean the combustion blower housing.
  • Inspect and clean the drip pan, condensate lines, and the evaporator coil.
  • Clean the burner assembly.
  • Ensure the ignition system is cleaned.
  • Test all safety controls.
  • Inspect the heat exchanger.
  • Check the flue system for any abnormalities or wear.
  • Check and tighten control box wiring.
  • Clean, or better yet, replace the air filter.
  • Check the duct system.

STEP 4: Check and Change Your HVAC Air Filters

Commercial HVAC maintenance has a lot to do with increasing and maintaining the efficiency of your systems. Regularly checking and changing air filters can be a simple, yet highly effective, way to do this and to keep the air clean and safe for employees and customers.

STEP 5: Program Thermostats

Programming thermostats is an excellent facility maintenance practice. Because of this, you ensure your thermostats are ready and programmed for the seasonal change. This is a great way to save money, time, and hassle. 

Regular checks of the programming assure that your system is optimized for the season. Even if your building has a great automation system, periodic manual checks will confirm it’s operating your HVAC system properly.

Additional HVAC Maintenance Tips

Clean or Change Air Filters Every Month

Air filters are a spot in your system that can collect a ton of debris. It is extremely important to remove that build-up of debris every month. In fact, depending on your system and the area in which your commercial building is located, it may be prudent to clean filters every 2 weeks.

Increase Energy Efficiency

The discrepancy between proper commercial HVAC maintenance and poor maintenance is a difference of approximately 15%. This means you could be throwing buckets of money away every month due to something as simple as a blocked air filter.

Air Quality is Important

A good building manager or owner takes good care of occupants. Dirty air filters can not only hurt your bottom line, but can also cause adverse health effects. Because of this, it’s important that we remember our obligation to the tenants or occupants by keeping air filters clean and fresh. A true benefit for both parties.

Call an HVAC Company if You’re Unsure What To Do

Sometimes it takes a trained professional to certify that your HVAC systems are being properly maintained. If your bills are high, your system doesn’t seem to be running efficiently, and you can’t seem to figure out why, it might be time to call a pro.
