How To Know Your AC Needs Repair

As temperatures are beginning to rise, many people will be switching on the air-con system for the first time this year. People who really appreciate their air-conditioning systems look after them properly. They have a service agreement with a reputable company.

Under these agreements, HVAC engineers will come regularly to give the AC unit a health-check. Any failing parts will be replaced or repaired. That reduces the chances of the system failing to work when it is most needed. It also reduces energy bills, because the air-con system will be running at maximum efficiency.

However, even systems that get the best care can go wrong. A problem may not cause the system to fail completely, but any issues should be resolved because a unit that is not working properly costs more to run.

It is always a good idea to give your AC unit a test run before you need it for environmental control. It is far better to discover problems before the air-con becomes essential. Test the unit a few weeks before you expect to need it for comfort. If there is a problem, you will have ample time to get it sorted out, according to an expert in AC repair in Columbia, TN.


One of the indications that your unit might need to be repaired is if it is making strange or loud noises. All units make noise. The motor and the fan generate the noise. If either of these develops a fault, it can alter the sound the unit makes. If your unit sounds different, get it checked out before it fails.

Energy costs

When you switch on your AC unit, you should make a note of the date. You will most likely be increasing energy consumption within the home, and you can expect higher energy bills. It is useful to compare your current year’s energy bills with what you paid last year, or your current month’s energy bill with the previous month. If your bills have increased more than usual, that could be a sign that your AC unit is burning more fuel than it should be.

Ice on the evaporator coil

As air flows over the evaporator coil, it comes in contact with the coil’s surface, which is cold. This lowers the temperature of the air. While ice on the coil might seem to make sense, it is actually bad news. Instead of pumping cool air, the unit will be pumping warm air, so that problem needs to be fixed.
