4 Signs Your Heating and Cooling System Needs Repair

One of the best ways to prolong the life of your heating and cooling system is to change the filters regularly, have regular professional maintenance, and make sure repairs are done in a timely manner. That's why it's important to know what signs to look for to know when a repair may be needed. Here are 4 typical signs that indicate the need for HVAC repair in Marietta.

Strange Sounds

You may not usually notice when your heating and cooling in Marietta is running because it should be quiet enough that it's just a normal background noise that you're accustomed to. However, that can quickly change when there's a problem with either the heating or cooling system. Listen for any changes when the unit is running, such as banging noises, whistling, or groaning noises. These sounds all indicate that something is wrong with at least one of the components and the unit needs attention right away.

Strange Smells

Any unusual smell shouldn't be ignored either. Even if you're just smelling mold or mildew, there's a good chance that either the unit or the ducts need to be cleaned for the health of the HVAC system and the health of the home's occupants. More serious odors like burning smells should be addressed immediately because this could indicate a problem with the electrical wiring or overheating, all of which could cause electrical shock or fire. If you notice a burning smell while the system is running, shut it off immediately and call for repair.

Reduced Cooling or Heating Efficiency

There are a few typical ways that homeowners will notice that their system is running inefficiently. First, they notice that the home just isn't staying as comfortable as it once did. It may be too hot in the summer or too cold in the winter, or there may just be hot or cold spots in the home. In addition, you may notice the energy bill going higher even if you haven't adjusted the thermostat at all. This indicates that the system is working harder than normal just to keep it at the same temperature. Finally, if you notice there is no air coming out of the vents, there is probably a problem with the blower. A broken blower will be unable to keep the house cooled or heated properly.

Power Loss

Any sudden power loss to the unit indicates a need for repair. If the unit is shutting off abruptly or the breakers in the home are being tripped by the HVAC system, a repair is necessary as soon as possible.
