Common Causes of HVAC Failure And How To Prevent Them

Air Conditioning Repairman

Summer is upon us, and with the change of the seasons come high humidity, scorching temperatures, and the need for a bit of relief. As much as we treasure these days of warm, sunny fun, we do need to retreat occasionally into the superb comfort of a well-functioning HVAC system.

Southern temps and climates naturally call for HVAC system use all year round. While we don’t give much thought to the consequences of a broken system until we experience the discomfort of heat and humidity, the reality is that living in these areas of the country calls for proactive maintenance and repair of systems to ensure that they are running efficiently.

Why do HVAC systems break down?

Over time, an HVAC system experiences wear and tear like most mechanical systems. They must be appropriately assessed and maintained to ensure that we remain cool and comfortable when hot temperatures hit. Here are some common reasons that your HVAC system may be on the fritz, and what you can do to prevent small issues that become significant breakdowns if not addressed.

  1. You may have a dirty HVAC filter. One of the most common issues that causes AC system failure is a dirty air conditioner filter. Most filters last only 30 days, and when the system runs longer and cycles as it does in hotter climates, the filter will need to be checked and changed regularly to avoid overtaxing the system. Getting your system up and running efficiently is as simple as replacing your dirty filter with a clean one.

  2. Your thermostat may be malfunctioning. Your thermostat is an essential component of your HVAC system. It controls your system to ensure that heating and cooling components are working properly. Check the thermostat to ensure that batteries are still working; change and replace if necessary. If this doesn’t do the trick, consider calling in an HVAC professional to assess the real cause of thermostat malfunction.

  3. You may have evaporator coil issues. The evaporator coil is located inside your home near the central hub of your HVAC system. It absorbs heat and humidity in the air that is then rerouted outside. If this coil becomes dirty or eroded, it will not be able to absorb heat and humidity inside the house, causing the temperature to rise.

  4. You may have dirty condenser coils. The AC condenser coil is located outside your home in the AC unit. Because of its location, the condenser coil can become dirty with outdoor debris and buildup. Too much dirt on the condenser coil can strain your unit, causing it to work harder and perform less efficiently than before. Over time, this hard-working unit could break down prematurely, shortening the life of your air conditioner.

  5. Your refrigerant may be leaking. When refrigerant leaks out of your HVAC system, it will cause indoor temps and humidity to rise, causing discomfort to those inside your home. A leak can be repaired after performing a leak test to get your system up and running once more. Refrigerants can be highly toxic to pets and people; have a trained HVAC service professional assess your suspected leak and make recommendations for repair.

  6. You may have a clogged drain line. Like the filter, the drain line can get clogged with dust, dirt, and lint inside your home. If the drain becomes clogged, your drain pan will fill up with water and overflow, eventually causing damage to your AC system. If your drain line and pan are in a location you feel you can get to, you may empty and clean them yourself. If you don’t feel comfortable performing this maintenance yourself, call in a service professional to clean and re-install components correctly to get your system up and running again.
