The HVAC system in your home is responsible for ensuring that the climate within the interior living space remains comfortable. However, once the system is in need of repair or replacement, you may find that your home suddenly becomes uninviting. Still, before the actual breakdown of a system, your unit will likely develop signs of disrepair. Here are a few of them:
If your HVAC system starts to make unusual sounds, such as clanking and banging noises, your system may be about to fail. These types of noises are often associated with loosened components of a unit. In some instances, a system part may become completely dislodged.
Sometimes, loosening occurs due to the vibrations produced by the unit as it is operating. However, once a component is completely out of place, your system may not function as it should. Since each component of your system may affect other system parts, it is best to have the unit inspected by an HVAC specialist, like Getzschman Heating, LLC, as soon as you notice unusual noises.
Uneven Cooling or Heating
If the size of your unit is sufficient for the square footage of your living space, the rooms of your home should all be well climatized. If you notice that one area of your home is much cooler or warmer than other areas, your system should be checked. Sometimes, inconsistent cooling or heating is due to a duct problem. Ducts can become dirty over time, and the debris can block the free flow of air into a room. In addition, a damaged duct may allow air to escape before it enters your home. How can you help your ducts stay clean? Make sure you change your air filters about every 3 to 6 months -- depending on your manufacturer's instructions -- and more often if you have pets or a large family.
If you set your thermostat to a specific temperature and the system of your home does not seem to respond properly, there could be a problem. Sometimes, a thermostat develops mechanical issues. For instance, if there is faulty wiring involved, the signal from your thermostat may not be properly relayed to your system. In addition, issues with the compressor of your unit can cause the system not to respond.
No Cool Air
If your air conditioning system is blowing air into your home but the air does not seem to have been cooled, your system may require the addition of more refrigerant. However, the refrigerant in your unit should actually last your system's lifetime. And since refrigerant can be expensive (hundreds of dollars), you should make sure that you check for leaks first before adding any more.
To have your HVAC system inspected, consult with an HVAC specialist in your area.
