Signs to spot faulty repairs in an AC unit

Spotting faulty repairs might seem daunting, but it’s not when you know the signs to look for in your AC system. Here are the signs that your AC unit has faulty repairs.

1. Your unit is still blowing warm air

Various unresolved issues could be behind your AC blowing warm air. After assessing the unit to find reasons behind warm air instead of cooling air, the technician should fix it. Then, if everything goes well, you shouldn’t have to deal with warm air again.

Stubborn thermostat issues are one of the things that could cause your AC unit to blow warm air. It either has problems with the settings, or it needs new batteries. However, note that these issues are fixable; if your control settings have been adjusted after a repair and it’s still not working, it’s a sign that the repair was not done correctly.

A once-broken compressor repaired incorrectly will also cause warm air to blow from your AC. If not a poorly rebuilt compressor, the refrigerant is still leaking, so your AC ends up acting up.

2. Consistent high air moisture content in your home

Usually, an air conditioner helps regulate humidity levels in your home. If the post fails to do so, it indicates that it has a calibration issue that an expert technician can fix. The conditions in your home should improve after fixing a calibration issue in your AC.

The lack of changes in humidity content in your space only shows that the problem is still intact. Pools of water around the windows and feeling clammy further show you that repairs on the unit didn’t change anything. Please take it as a sign that it’s time for a new AC unit.

3. AC unit is still short cycling

AC turns on and off under normal circumstances, although there’s a timer on the cycles, even on hot days. Some issues in the AC can cause it to turn on and off randomly. One of those reasons is a faulty thermostat which is often repairable.

A technician can also change the placement of the thermostat to stop the short cycling. Another issue that could cause short cycling but is repairable is clogged filters. Cleaning AC filters works but replacing them is ultimately more effective.

Fixing a faulty compressor could also stop short cycling. If repairs on these parts don’t keep your AC unit from short cycling, then it means that they were flawed.

4. Odd noises from your unit haven’t seized

When you hear odd noises from your AC, the first thing that comes to mind is something broken inside the unit. However, you must be able to tell the sounds from an AC unit apart, between what is normal for an air conditioner and what isn’t. The unit deserves your attention when the unit has clunking or hissing sounds.

Hissing sounds indicate that the refrigerant is leaking. You shouldn’t take up repairs to fix a refrigerant leak. A professional has the equipment and skills to fix the leak and refill the refrigerant. Failed repairs are usually evident if the sound comes back or fails to go away.

A clunking or rattling sound shows that pieces of metal or plastic are trapped in the casing. An expert can put loosened parts of the unit back to eliminate rattling. Such repairs should work unless the sounds continue.

5. Water leaks

Condensation is an expected process in cooling. However, watch out for condensing pools. It shows that the system is not working as it should eliminate excess moisture. Pools of water might cause serious damage to the unit’s interior components.

Repairing the condensate line puts an end to AC water leaks. The repairs usually involve unclogging the line. However, the leaking continues if repairs don’t work or the technician fails to do it correctly.

6. Fluctuating electric bill

Faults in the AC unit cause an air conditioner to work harder than intended. Not only does it wear the unit out before it reaches its life expectancy, but it also causes high power consumption. As a homeowner, your wish should be to ensure your unit is energy efficient.

7. Foul smell from the unit

Sometimes repair and maintenance go hand in hand. For example, the conditions in an AC can get moist now and then, facilitating mold growth. As part of repairs, your technician may clean the mold and any standing pools of water to eliminate odors.

The cleaning process to remove the bad smell must be thorough. Otherwise, the mold will grow back. You have to reach the hidden parts as well. Usually, installing UV lights in the unit afterward helps keep persistent mold spores from sprouting.
