What Is the Most Common Problem With HVAC Systems?

One of the most frequent issues faced by HVAC systems is lack of proper maintenance. This might sound simple, but keeping an HVAC system in top condition involves several important steps that are often overlooked until the system starts malfunctioning.

Why Maintenance Matters

Regular maintenance ensures that your HVAC system runs efficiently and lasts longer. Neglect in this area can lead to increased energy bills, poor airflow, and premature breakdowns. Essentially, a well-maintained HVAC system is less likely to develop serious issues.

What Does Proper HVAC Maintenance Include?

A thorough maintenance check generally includes:

  • Inspecting and changing the air filters: Dirty filters restrict airflow and reduce efficiency.
  • Checking the thermostat settings: To ensure the system runs when you need it and saves energy when you don’t.
  • Inspecting electrical connections: Loose connections can be a safety hazard and reduce the lifespan of your system.
  • Lubricating moving parts: This reduces friction and helps your system run more smoothly.
  • Inspecting the condensation drain: A clogged drain can cause water damage in the house and affect indoor humidity levels.
  • Checking system controls: Ensuring the system starts, operates, and shuts off properly.

Other Common HVAC Issues

Besides lack of maintenance, several other problems can plague your HVAC system, affecting its efficiency and functionality.

Refrigerant Leaks

When the coolant starts leaking in an air conditioner, the unit will not perform correctly, and the temperature will fluctuate. Repairing this issue is not just a matter of replacing the coolant; it’s crucial to find the leak and repair it.

Dirty or Clogged Filters

We touched on this briefly under maintenance, but it’s worth noting again that a clogged filter is one of the most common issues that leads to HVAC inefficiency. It’s an easy fix but one that needs regular attention.

Broken Thermostat

A malfunctioning thermostat can lead to problems with the comfort levels in your home. Sometimes the issue is as simple as needing new batteries or recalibrating the unit.

Mechanical Wear and Tear

Like any machine, parts of your HVAC system can wear out. Belts and bearings may need to be replaced, and issues like these can cause overheating or poor heating and cooling performance.

Uncleaned Coils

The evaporator and condenser coils in an HVAC system can accumulate dirt over their use. Dirty coils reduce the system’s ability to cool your home, causing the system to run longer, thereby increasing energy costs.
