5 Signs You Need AC Repair July 12, 2019

Mount Vernon, Knox
5 Signs You Need AC Repair, Mount Vernon, Ohio

Summer is here, and having a reliable AC unit is necessary for staying comfortable. The last thing you want is to have to call for emergency HVAC services in the middle of a heat wave. Here are five clear signs you need air conditioning repair today.

How to Know You Need AC Help

1. Warm Air

The first sign of a problem with the AC is no cool air, no matter how you set the thermostat. Often, this issue has to do with the compressor, which requires an expert HVAC service technician to diagnose and fix. You may also have a coolant issue where levels are too low or leaking. Inconsistent temperatures, on the other hand, may mean a component is about to fail or that the ductwork needs to be checked for blockages or seal repairs.  Don’t forget to check your filter, too.  Clogged filters cause numerous problems with both air conditioners and heaters.

2. Excess Moisture

If you notice a buildup of moisture around the components, it may be leaking coolant, which can be dangerous for your health. It also may be condensation, which indicates a clogged or broken drain tube. You will usually see a pool of water around the furnace or near where the drain line runs. While not dangerous, it can lead to mold and rust around the system. Too much moisture can also take the form of too much humidity in the air. An HVAC contractor can clear or repair your AC’s drain system to remedy this issue.

3. Odd Smells & Sounds

HVAC servicesThe system may make a particular sound when it runs, which can be fine, but any new ones may signal an issue. Grinding, squealing, and clanking could point to loose parts, debris, or a breakdown. If you smell something odd as well, it may be from an electrical component burning out.

4. Faulty Thermostat

Sometimes the thermostat is the culprit behind a malfunctioning AC, especially if you notice the unit doesn’t kick on. This could mean that the thermostat is no longer communicating with the unit. Consider upgrading to a digital model that can be programmed in advance to save energy and money in utility costs.  Additionally, if your thermostat uses batteries, check to make sure that they have a full charge.

5. Rising Bills

Older units become less efficient over time. When your electricity bill is rising every month, it may be time for an upgrade. Parts may be working harder now, especially if they haven’t had regular maintenance. For newer units, inefficiency may be as simple as having an expert come in to inspect, clean, and replace parts.
