What are the Most Common HVAC Issues?

April 29th, 2021

As the weather warms up, we depend on our HVAC systems to keep us cool and comfortable. If your HVAC unit is not working properly, there are a few possible reasons why. Our technicians from Ferguson Heating and Air Conditioning Company want to walk you through the most common problems we see on a daily basis. Even if you cannot fix your HVAC system, you can understand why it is malfunctioning. Our Ferguson family is standing by to help with your HVAC troubles whenever you need us.

Common HVAC Problems:

Airflow Issues—When your filter is dirty or clogged, your HVAC unit will have to work much harder to try and cool your air. As a result, your unit will not be as efficient, and your utility bills could spike. Your indoor air quality will also suffer as the filter cannot catch particles effectively anymore. We recommend checking and cleaning your filter once a month to ensure it is functioning properly. At least every 3 months, you should plan to replace the filter. If you have a pet or someone who suffers from allergies, you may need to replace it more frequently. We receive a lot of service calls because homeowners recognize that their unit is not blowing out cool air effectively anymore. The source of the problem is quite often their filter.

Thermostat Troubles—Check the settings on your thermostat. If you have a smart or programmable thermostat, you can program your temperature for when you are there and when you are away. This can save you money, but also give your HVAC unit a break so it does not become overworked. An overworked HVAC system can fail sooner than expected. If your thermostat is exposed to direct sunlight, the unit could be registering the wrong temperature. Taking a minute and reviewing your thermostat manual may help you resolve the problem without a service call.

Coil/Condenser Unit Complications—If dirt and debris have fallen into the top of your outdoor condenser unit, the fan may not function properly and disperse heat as it should. The coils can become dirty and collect mold and mildew. Your unit will not function as efficiently, causing the HVAC system to be overworked. An overworked HVAC system often leads to a premature replacement. You can clean the blades and coil using a clean cloth. The coil could be cleaned using a vinegar and water solution if needed to remove mold and mildew. Make sure to turn the unit off before attempting to clean it.

Tripped Breakers/Blown Fuses—When your Furnace/Air-Handler is overworked, the system will sometimes trip a breaker. You can check your breaker box for evidence of a tripped breaker. An overworked furnace/air-handler generally happens when a filter has been neglected. The system must work too hard to push through air and the blower will increase its energy consumption, which could lead to a tripped breaker.
