7 Signs Your AC Needs a Tune-Up

You need regular air conditioner tune-ups if you want your unit to work in perfect order. Timely tune-ups can prevent the hassle of expensive repairs in your Northern California place of business or home. They can also help you save money. There are several signs that indicate a long overdue tune-up from bad odor to poor airflow.

These are a few signs that it is time to get an air conditioner tune-up:

1. Strange Noises

You may have gotten used to strange noises coming from an air conditioning unit that is old. However, if you notice any new sounds that are not normal, it may be time to get a tune-up done. This includes whistling, buzzing, hissing, and an alarming banging sound. Buzzing noises are generally produced when the airflow is obstructed partially.

2. Sudden Rise in Utility Bills

Your air conditioner could be drawing more power than usual if you observe a sudden spike in energy bills. This is because the heating and cooling system can account for two-thirds of residential utility bills. High bills are typical of lack of maintenance. You need to schedule regular tune-ups as the air conditioner becomes old. The system needs to work harder with time because of blockages and dust traps.

3. Inadequate Cooling

Your air conditioner will not fulfill its purpose if it blows out warm or room temperature air. This is usually because of dirty air filters or coils that are covered in dust and grime. An air conditioner tune-up should fix the problem quickly. It’s also possible that the unit is low on refrigerant. In this situation, the technician will fix the issue by recharging the refrigerant. They will also inspect the electrical wiring during the tune-up.

4. Bad Odor from the Air Conditioner

You want to tackle any bad odor coming from the air conditioner quickly. This is because it could be because of mold or fungus, clog in the condensate drain pipe, or wet filters. It may also mean that you need to replace the system’s wire insulation if the foul odor is coming from the vents. Decaying and trapped animals can give off a pungent smell too.

5. Weak Air Flow

Everyone depends on their air conditioning units to provide consistent air flow for maintaining the desired indoor temperature. You may suffer from increased bills and inconsistent temperatures if this does not happen. It will make your air conditioner work harder than usual. Poor airflow is usually because of a leaky duct, clogged filters, and other reasons. It is time to schedule an air conditioner tune-up if you feel the airflow coming from the unit is weak.

6. High Humidity Levels

The weather can become extremely sticky during spring and summer. This doesn’t mean that you need to be hot and sweaty indoors as well. An air conditioner should lower the humidity levels in a house automatically. A tune-up may well be due if the air conditioner is unable to keep the room’s humidity levels low. This is usually because of low refrigerant levels.

7. Leaking Water

Air conditioner leaks are mainly because of leaking refrigerant or a clogged drainpipe. Refrigerants are used for cooling air and can result in condensation build-up. However, pooling water should not leak or accumulate in the house. The refrigerant is probably not working as it should if you notice leaks around the unit.
