Many homes in Nashville rely on their central air conditioning in the summer. For the most part, they are able to use a set it and forget it approach to their central air conditioning after turning the AC on at the beginning of summer. It should be able to run until the fall without any issues, but this is not always the case and you may need AC repair in Nashville if you start experiencing a problem.
A central air conditioner that did not receive annual maintenance before summer, has been overworked in hot temperatures, or is getting older may start having problems over the course of the summer, making it necessary for you to get Nashville AC repair.
Most Common AC Repairs in Nashville
There are several different problems homeowners in Nashville often experience with an AC, although the majority of issues often fall into a few different categories. These are some of the problems that most often require AC repair in Nashville:
AC Does Not Run
When your AC does not turn on at all or powers off mid-cycle, it is likely a power or setting issue. There are a few things you can check before calling a Nashville HVAC repair company.
First, make sure that your thermostat is set to the right temperature for cooling. You may also need to replace the batteries in your thermostat. If the batteries are functioning and your AC still does not power on, check the fuse box to see if the circuit has been tripped and reset it if so. If none of these steps fix the issue, a professional technician can do a deeper dive to assess the problem.
AC Blows Hot Air
If you can feel warm or hot air coming out of the vents, check the thermostat settings to be sure they are still set to cool. The next steps are to change your air filters since clogged air filters reduce airflow in a central AC which can cause the condenser to freeze and make it impossible to cool air.
You should replace an air filter monthly at a minimum, but certain systems may need more frequent replacements if they run continuously or you live in an area that is particularly dusty. An HVAC technician can also diagnose further issues if replacing the filter does not solve the problem.
Refrigerant Leaks
When an AC does not have enough coolant, it will have to work harder to keep your home cool. You may also start to see frozen coils or compressor damage. A refrigerant leak occurs when there is corrosion or physical damage to your unit so you will need an HVAC technician to repair the damage as well as refill the coolant.
Clogged Drains
The condensate drain can get clogged by debris, causing water to build up and often leading to the development of mold. This can be harmful to your home and cause odors. Clearing drains is generally part of annual AC servicing, but a clogged drain can cause problems if you missed a regular visit or dirt has built up.
AC Unit Leaking
Some water leaking from the outdoor portion of an AC unit is natural, but if you notice excessive water, this could be a sign of a problem, such as a blocked condensate drain, a broken condensate pan, air filters that need replacement, or a problem with the unit installation. The cause of leaking can one of several, so it is best to have professional AC repair to diagnose the problem.
Unusual AC Noises
Your AC should sound similar every time it runs. If you start to hear rattling, banging, squealing, buzzing, hissing, or any other sound that sounds that makes it seem like your AC is struggling most likely indicates a problem. An AC repair expert can use sound to identify a specific problem.
Electrical Issues
The different components of an AC need to make an electrical connection each time the unit runs. Corroded wires and years of wear and tear can prevent that electrical connection. This requires professional repair to tighten connections and replace any electrical components that may have worn down.
Sensor Problems
An AC has a thermostat sensor that should be next to the evaporator coil, but not touching it. If the coil shifts into the wrong place, it can cause an AC to cycle continuously or not cool adequately. An AC that seems to be working harder, not turning on when expected, cycling continuously, or leading to a higher than normal energy bill can all be signs of a sensor problem, but you will likely need an AC repair technician to diagnose the problem.
