simple repairs for your air conditioning

Commercial HVAC Maintenance Is About More Than Temperature Control

While a dirty home air conditioner may cause illness in several people, a poorly maintained commercial HVAC unit can potentially cause hundreds of people to become ill, and may even cause death. At the very least, it can cause customer and tenant dissatisfaction and complaints about things such as uncomfortable temperatures and foul odors. Proper regular professional HVAC maintenance can prevent a number of potentially dangerous problems.

Airborne Illnesses

When you mention air conditioning and illness in the same sentence, you can't help but think of the outbreaks of Legionnaire's Disease that have occurred over the years. The bacterium that causes this disease, Legionella, was first discovered in 1976 when an outbreak in a Philadelphia Legionnaire's convention killed 34 people. These bacteria breed in water such as that found in evaporative condensers of modern air conditioning cooling towers. To prevent the growth of Legionella, commercial water towers should be disinfected, not simply cleaned, on a regular schedule. 

Inconsistent Airflow

In commercial buildings, there may be limited access to ductwork, especially between floors. This can make detecting leaks difficult and lead to hot and cold spots within the building. The U.S. Department of Energy reports that a standard ductwork system may lose up to 40% of its air from leaks. A commercial HVAC professional can locate and fix leaks before they become a serious problem for you, your customers or your tenants.

Efficiency Loss

An inefficient HVAC system can run up a substantial electric bill. Simply having a professional clean your condenser and evaporator coils twice a year can improve your efficiency up to 16%. Improperly operating dampers are another problem that can cost you money and affect indoor air quality. They need to be cleaned and well lubricated a few times a year to ensure optimal operation.

Poor Indoor Air Quality and Odors

Something as simple as a dirty air filter can drastically affect indoor air quality. Odors can be caused by stagnant condensed water, overheating, or melted debris on the heat exchanger. Indoor air pollution from dust and mold can contribute to respiratory illnesses such as asthma and emphysema, causing lost workdays and decreased productivity. 

As you can see, a poorly maintained commercial HVAC unit can be costly in the long run. Most of the problems can easily be avoided by having regularly scheduled professional HVAC maintenance. Call a local HVAC specialist like Soco Air Conditioning to have your system thoroughly inspected.
