The HVAC system is a major energy consumer especially for commercial buildings and over time it loses efficiency without proper care and maintenance. With the arrival of spring season, it is the perfect opportunity to pay attention to your commercial HVAC system and carry out some spring cleaning to get rid of accumulated dirt, dust, and germs in your HVAC system and upgrade your HVAC controls to improve efficiency and reduce utility bills.

There are several advantages for carrying out spring cleaning for your commercial HVAC system including improved ventilation, enhanced comfort, increased efficiency and reduced utility bills. In addition, it will also increase the lifespan of your HVAC system.
In this article, we take a look at some of the spring maintenance tips for your commercial HVAC system.

Replace the Air Filter

Over time, the air filter in your commercial HVAC system accumulates dust and dirt which not only contribute to indoor air pollution but also put extra load on the HVAC system.  Cleaning air filter will improve indoor air quality in your space as well reduce energy costs of your building. Operating your commercial HVAC systems with clean air filters can reduce energy usage by up to 15%.

Clean HVAC system components

HVAC system indoor components including evaporating coils, blower fans accumulate layers of dust, dirt, germs, scaling and so on which greatly reduce system efficiency and lower indoor air quality. Make sure during spring cleaning, these parts are properly cleaned for the upcoming season. Also do not forget to clean and lubricate fan blades for smooth function.

With the prevalent of covid-19, it is possible that the virus can circulate in the air through the system and increase risk of transmission within a building due to poor ventilation. This is why it is now imperative more than ever that before reopening you carry out a deep cleaning of your commercial HVAC system. You should ensure you get the services of professionals who follow covid-19 disinfection protocol.

Ensure proper refrigerant level

Cooling systems need to have the right amount of refrigerant to capture and release heat properly. The refrigerant in cooling system is found in evaporating coils- these evaporate the refrigerant to absorb heat from the surrounding area and is transferred to condenser coil where it reverts back to liquid form and heat is released either into or outside the building, ensuring the heat pump or cooling system is functioning properly.  It is imperative that the proper refrigerant level is maintained. Without it, commercial HVAC system will have lower efficiency and eventually lead to system breakdown, requiring major repairs.

Upgrade HVAC Controls

With commercial HVAC systems accounting for more than 50% to 60% of the total energy consumption, upgrading your HVAC controls can be the best investment for your HVAC system this season. Smart commercial HVAC controls such as DDC systems can increase your system efficiency up to 40%. Today’s smart commercial HVAC control also allows you to monitor and control multiple building systems in a unified platform and also provide a hassle-free energy management system, improving efficiency and reducing utility bills.

Inspect and clean drain lines

The cooling drain line can become clogged leading to the unit shutting down or worse, leaking and triggering serious water damage to the building. Inspect your drain lines and condensate pans and make sure that they are not clogged with debris, mold or mineral deposits and clean them properly. If you have a HVAC monitoring app or a newer HVAC system, it can notify you when the drain pan is filled with water so you know that the line is clogged and fix the problem before it causes any major damage.

Clean outdoor units

In addition to cleaning HVAC inner components, you should also ensure that the outdoor cabinet that holds the condenser unit and other components are clean. During winter season, there can be build-up of debris including leaves, branches or other materials that can obstruct the vents and reduce airflow, thereby reducing efficiency. Make sure these are removed and cleaned properly.

Inspect and repair electrical wiring

Another important thing to note during spring cleaning of your commercial HVAC system is to properly check and test control box, wiring and connections so that they are secure and without any damage. Examine all wiring for any signs of damage, including rodent nests, burnt wires, and loose connections and fix the issue before it leads to major problems.
