AC is one of the crucial components of every home, as it keeps you comfortable and safe. Unfortunately, air conditioners also develop problems due to normal wear and tear, poor maintenance, or old age. If yours is showing signs of a problem, have it fixed as soon as possible. Don't wait until it stops working completely to avoid paying more for repair costs or needing a replacement in some cases. Here are five signs that you need AC repair services. 

Strange Smell

If your AC starts producing a strange smell, it has a problem. It could be mold growth or the burning of wires inside the unit. Parts of the AC, such as the fan motor, compressor, or circuit board, may also be overheating, causing strange odors. These smells will cause discomfort and are dangerous, given that mold can cause health problems. Call a professional to diagnose the issue and fix it immediately if you notice any odor coming from your air conditioning unit.

Warm Air

If your AC produces warm air, it could indicate a broken compressor or low refrigerant levels. There also could be a problem with your evaporator coils. Most of the time, an AC producing warm air is an issue you can fix. Before calling an AC repair professional to check what's wrong with your unit, ensure you have set the thermostat correctly.

Unusual Noises

Does your AC produce squealing, grinding, or scraping sounds when turned on? 

There could be a problem with its belt. Also, the compressor parts may have become loose. 

Other issues that can make your AC produce unusual noises include a malfunctioning relay switch expansion valve or refrigerant piping. 

Rising Utility Bills

If your electricity bill has risen significantly, your AC could be the cause. Air conditioners need a lot of electricity to operate, but a considerable rise in utility bills could signify inefficiency caused by a malfunction within the unit.

There are several reasons why your AC would increase your electricity bills significantly. These include a dirty air filter, duct leaks, low refrigerant, and poor installation. 

Water Leakage

If your AC is leaking water, there could be a problem with its drain line, such as clogging due to mold or dirt build-up. A dirty air filter, failed condensate pump, and low refrigerant levels can also cause water leakage. 

An AC repair technician will be in a better position to identify the issue and fix it. Contact a professional to learn more about AC repair.
