Common HVAC Problems


HVAC units are essential in residential and commercial setups and have many benefits. These systems take up a significant energy amount and should be kept in the right state to lower these bills. HVAC units are different, and homeowners must consider various things to make the best decision. 

HVAC systems require frequent maintenance practices to keep them in the right state; some are easy, while others are more complex and need help from certified technicians. These technicians are equipped with the latest HVAC Software that enables them to detect all issues and solve them accordingly. 

These units experience specific issues during their lifespan; below, we discuss some. 

  • Clogged Drain Lines

The most common issue with HVAC units is clogged drain lines. Remember, your AC creates condensation like a glass of soda during hot temperatures. The unit’s pipes might get clogged with time, causing water to back up in your unit. 

This, in turn, causes severe damage to the motor and other electrical systems. Homeowners should locate the drain’s beginning when the lines get blocked and eliminate any water from the drain pan. 

  • A Continuously Running Blower Motor

A continuously running motor does not always suggest a mechanical problem, but it shows your system is overworking. The following reasons would make your blower run constantly;

  • Spoilt fan relay
  • Thermostat failure. 

Troubleshooting this issue is easy; you should ensure the thermostat is not turned on and turn the circuit breaker on to check whether it resets the system. However, you should consider calling an HVAC expert if the problem persists.

  • Dirty Coils

HVAC evaporators turn the refrigerant from liquid to gas. Remember, the refrigerant can absorb most heat in the surrounding when in a gas state, enabling your building to cool. Evaporator coils are mainly blocked by debris and dirt, which stops air from reaching the heat exchanger. 

It will help to clean these coils using a detergent and water to solve this problem. Also, consider spraying the debris and giving it a short while to loosen it. 

  • Insufficient Airflow 

The key to having an efficient HVAC unit is proper airflow. Remember, poor airflow makes the unit overwork, increasing energy bills. An overworking system also lowers the system’s ability to retain steady temperatures. 

The most common cause of restricted airflow is dirty air filters, explaining why you should clean them often. Homeowners should also change the filters after three months to ensure they are in the best state. 

Unclean filters restrict airflow, making your unit to overwork. On the other hand, clean filters ensure there is no dust accumulation in the HVAC, which prevents future issues. 

  • Poor Air Quality

Indoor air quality is the leading issue facing HVAC units. This issue is mainly experienced in old and faulty units. Traditional HVAC units move air without facilitating air intake, which can cause problems.
