4 Common Signs You Need AC Repairs

For those in Texas, it’s already sweltering outside, and you’re probably running the AC non-stop to stay cool. The last thing you want is to deal with a broken down HVAC system on a hot day. To ensure this doesn’t happen, pay attention to the following signs to know if you should schedule HVAC repairs.

1. Unusual Noises

While you will hear some rumblings as the system turns on, you shouldn’t hear loud bangs and clanging coming from the HVAC system. Strange noises are typically caused by loose parts or debris caught in the system. When these parts are not well secured, they can rattle around. A loose belt or fan blades that are hitting something may also be a culprit. Whatever the case, it’s best to call a professional to inspect the unit.

2. Strange Smells

Strange smells may occur when the system is not able to properly circulate air, which can cause a buildup of dust and other particles in the system. Other common causes of unpleasant smells from your AC include dirty air filters, a buildup of mold or mildew inside the ductwork, or refrigerant leaks. 

3. An Inability to Cool Your Home

If you notice that some rooms are too hot or too cold, or the house isn’t very cool at all, something is wrong with the system. There are many possible causes, including an issue with the compressor, evaporator coil, or air handler. There may also be a refrigerant leak or a leak in the ductwork.  

4. Leaking or a Frozen AC Unit

A leaking unit can cause water damage to your home, while a frozen coil can prevent the AC from cooling the house effectively. Refrigerant leaks can occur in the evaporator coil, condenser coil, or compressor. Potential causes of a leak include dirty or clogged air filters, dirty coils, leaking ductwork, or low refrigerant levels. 

If the coils are frozen, the air conditioner might be low on refrigerant, or the filters are dirty. In either case, a technician will need to diagnose and fix the problem.
