Commercial HVAC Maintenance Checklist (Download Free PDF)
Businesses often neglect proper commercial HVAC maintenance because they believe it is too expensive or time-consuming. In reality, HVAC preventive maintenance will reduce the cost of repairs later on down the road by ensuring that your unit continues to function properly for years to come.
As with any other piece of equipment in your office or facility, even small problems with your HVAC unit can cause major problems down the road if left unchecked.
For example, if there is a leaky coil in one of your air handlers or an improperly installed control board, these problems can lead to higher energy costs due to increased electricity consumption as well as more frequent service calls.
This is why HVAC maintenance is necessary to keep your units running smoothly. In this blog, we’ll look at the commercial HVAC maintenance checklist in detail as well as reasons why you need to do regular maintenance as per the manufacturer’s instructions.
Understanding the Need for Proper Commercial HVAC Maintenance
When your cooling and heating equipment isn’t properly maintained, it can affect your indoor environment’s quality. This will affect not only your employees’ productivity but also their health.
Increase the Lifespan
A properly-maintained unit will also increase its lifespan and efficiency, which means it will use less energy than an un-maintained unit would require.
This can translate into significant savings for your business over time because you will need fewer repairs and replacements due to damage caused by a lack of proper HVAC maintenance!
And this could also increase the entire lifespan of your HVAC units.
Save Huge Energy Costs
Having a handing HVAC maintenance checklist is the most important to keep every single part of your air conditioning unit functioning properly: from evaporator coils, condensate lines, flue system, blower assembly, and ignition system to the heat pump, heat exchanger, combustion blower housing, gas furnace, and safety controls.
This is especially needed if you’re one of the biggest energy consumers. Even a small change in the increase in the tune-up and performance of the heating and cooling systems can have a marked difference in a huge amount of energy consumption, and thereby, save dollars.
Prevent Last-Minute System Failures
The HVAC unit is the most important thing to keep up with if you want your business to operate smoothly. One of the biggest reasons for this is because HVAC equipment can fail at any time even when you least expect it.
When this happens, it can lead to major problems for your office or warehouse.
Preventative Maintenance Checklist for Commercial HVAC Systems
Check and Clean the Condensate Drain Line
This is an essential part of your commercial HVAC maintenance checklist because it can lead to major problems if you don’t perform this task. If the drain line becomes clogged or blocked, water buildup in the air handler cabinet will damage the unit itself.
To prevent this, inspect the condensate drain lines, drip pan, and drain pans of your commercial HVAC systems periodically to make sure it is clear and free of debris or obstructions that could cause clogs or leaks.
Change Air Filters Regularly
The air filter is the most important part of any heating and cooling system. It catches particles that would otherwise be circulated into the air, which could cause health problems for your employees and customers.
The air filters in your HVAC equipment can become clogged with dirt, dust, and other contaminants over time. Changing them regularly will keep your system running efficiently, so it’s essential to ensure you change them every few months at least.
Air filters should be changed once every three months depending on usage and environment. Dirty filters restrict airflow and can cause your commercial HVAC systems to work harder than it has to, shortening your system’s life span.
This will help keep contaminants like dirt, pollen, and dust from entering your HVAC system and causing damage over time. If you don’t know how to clean air filters on your own, you can contact any commercial business owner offering HVAC maintenance to help you out.
Inspect Refrigerant Levels Regularly
It’s important to check the refrigerant levels in the HVAC systems regularly to detect leaks before they become large enough to affect performance or create safety hazards for your employees and customers.
Inspecting the refrigerant level involves measuring the pressure inside the unit with a gauge connected between its compressor and condenser and then comparing that reading against the maximum legal limit for an air conditioner at full capacity.
This is done to see any discrepancies and make sure the unit performs well during both heating and cooling seasons.
Clean the Air Handlers
The most critical component of a commercial HVAC system is the air handler, where the actual cooling or heating takes place and this should definitely be a part of your HVAC inspection checklist.
The air handler should be cleaned and inspected at least once per year. This can be done by a professional who can also check your energy consumption levels to ensure that the air handlers are running at their maximum efficiency.
Clean Condenser Coils
Condenser coils are the part of the HVAC systems that draws in air and cools it before sending it back into the building. Over time, these coils can get clogged with dirt and debris, which can cause an increase in energy usage and decreased efficiency.
To clean your condenser coils, remove them from the unit and use pressurized air to remove any remaining debris. Cleaning the condenser coil regularly will help your system run more efficiently and reduce energy consumption.
Along with your condensate lines, make sure to check the blower motor too, to make sure that everything is working well.
Check Electrical Connections for Proper Functioning
Most commercial buildings’ heating and cooling equipment have electronic controls that make it easier to program and operate than older models.
Even though these systems are more efficient than ever, it’s still important to have them regularly tested by a technician to ensure they’re working as intended.
Check if all electrical components are working properly by testing their voltage and amperage ratings against their specifications. If there is any discrepancy between them, contact your HVAC contractor immediately so they can repair or replace the faulty part of your unit.
You’ll also want to ensure all wiring connections are secure so they don’t pose fire hazards or result in electrocution risks during your commercial HVAC system use.
Check the Duct Systems for Indoor Units
If you use an indoor system, you need to check the indoor components, like the ductwork, as a part of the commercial HVAC maintenance checklist.
The duct system that connects your outdoor unit with your indoor units can be hard to see, especially if it’s hidden behind walls or ceilings. If you have any doubts about whether these systems need cleaning, check with a professional before spending time doing it yourself.
It’s best to clean out the duct as a part of your preventive maintenance tasks to make sure that you don’t incur high energy costs later.
