8 Commercial HVAC Usage Mistakes To Avoid

The installation of an HVAC system for commercial buildings is costly. Therefore, it’s essential for you or your team to take care of the HVAC system, follow the best practices, call in commercial air conditioning repair services when needed, and avoid the below mistakes.

Ignoring The Programmable Thermostat

If you installed a commercial HVAC system in your building within a few years, it will have a programmable thermostat as well. Many people don’t use it correctly and set it to a temperature for all the hours of the day. This can hugely impact the monthly energy bills.

To save energy and reduce the running costs of the HVAC system, use the programmable thermostat to your advantage. Take note of the times when more cooling is needed and the time of day when the HVAC system could do without cooling on priority. Set the thermostat according to the schedule and save money.

However, if your commercial HVAC system doesn’t have a programmable thermostat, consider replacing the regular thermostat with a programmable or smart thermostat.

Not Maintaining The HVAC Unit

Commercial air conditioning systems are sturdy, but they require maintenance to keep working well. One of the most common mistakes commercial building owners and managers make is ignoring the maintenance of the HVAC system. A thought behind this practice is that they think if the unit is working fine then it doesn’t need maintenance.

Ignoring the maintenance of an AC leads to increased energy bills, improper cooling, and frequent breakdowns. These things can increase the cost of running the unit because when the unit breakdown often, you will be spending more on repairs. To avoid this, you should follow the maintenance schedule.

Not Cleaning The Air Filters

Air conditioners depend on proper airflow and the air goes through air filters. When the air filters are clogged by dust and debris, they will restrict the airflow. Due to this, the AC won’t reach the set temperature.

In turn, the HVAC unit will work more intensely to provide the necessary airflow and cool the building. This process can damage any component of the AC leading to a breakdown. To avoid this issue, you can simply check the air filters every three months and clean or replace them.

Ignoring To Recalibrate The HVAC System

You should recalibrate the system bi-annually. Once before summer and then before winter. Moreover, adjust the thermostat settings accordingly as well. These small adjustments can make a huge impact and lead to energy savings.

Leaving Drain Lines Unattended

The drain lines of your HVAC system collect water vapors created by air conditioning or heating and remove them from the building safely. Usually, there is an exterior tray that collects the water that then evaporates into the air.

However, this tray and drain lines can be blocked due to dust, debris, and the growth of microorganisms. Blocked drain lines can induce water damage to the property. So, check the drain lines regularly and clean them.

Ignoring The Cleaning Of the Evaporator And Condenser Coils

The evaporator and condenser coils collect dust constantly during operation because of the air circulating through them. This can impede the performance and efficiency of your unit. To avoid cooling issues, keep the evaporator and condenser coils clean. You should clean them at least once a year.

You can use a commercial coil cleaner and other tools. Therefore, if you don’t have these tools, consult a professional.

Ignoring HVAC Repairs

It’s one of the biggest mistakes made by commercial building owners and managers. Putting off repairs of the commercial AC will only result in a small issue turning into a bigger problem that will cost you much more.

Putting Off Upgrades

A commercial HVAC system upgrade may sound like an unnecessary expense and that’s why many people don’t go ahead with it. However, upgrading to a newer HVAC system can increase efficiency and reduce HVAC costs in the long run. This is more important if your existing HVAC system is on its last legs.


The proper functioning of a commercial HVAC system is critical to keep employees and customers happy by giving them a cold or warm environment. Make sure you avoid the above mistakes and hire commercial HVAC companies Smithtown for maintenance and repairs.
