Fall in Lebanon, TN, brings cooler, drier air, so it’s time to switch your commercial HVAC system from cooling to heating. You can easily avoid the following four system malfunctions that tend to occur in autumn.

1. Overheating

Air filtration and good airflow are as important as ever during the fall. Overheating can occur in certain components. If you are observing the following signs, it’s time for immediate professional repair.

  • A cracked heat exchanger: The furnace flame is yellow instead of blue, the furnace creates a lot of soot, you see corroded or cracked parts or water is
    on the floor around the furnace. A cracked exchanger is particularly dangerous due to possible carbon monoxide exposure.
  • A malfunctioning motor blower: The vents have a burning smell, the entire system shuts down, there is weak or no airflow, you have excessively high energy bills or you hear strange sounds.
  • An overheating furnace: You hear strange noises, notice a burning smell or the furnace shuts off.

2. Thermostat Problems

Commercial HVAC systems last a long time, and timely repair helps to prolong their longevity. Sometimes, it’s not your HVAC system having the issue, but your thermostat. Some signs of a malfunctioning thermostat are uncomfortable fluctuations in temperature, unresponsiveness to temperature adjustment and continuous heating without turning off.

3. Old HVAC System

Older commercial HVAC units can be inefficient and tend to have sudden malfunctions and failures. If yours is more than 20 years old, it’s likely that it needs upgrading, and you should replace it.

4. Skipping Maintenance

As you transition from summer to fall, your commercial HVAC will need season-specific maintenance. Cleaning ductwork and evaporator coils, checking the ignition, adjusting supply registers, checking the furnace, inspecting the blower and belts and other maintenance and function checks are all routine services that our commercial HVAC technicians provide.

Fall is one of the best times for maintenance and repairs to prevent major heating system problems and expenses. Call us at Busy Bee Plumbing, Heating & Air Conditioning for the commercial HVAC services you need to keep your Lebanon, TN, business spaces comfortable all year round.
