Signs that Your AC Needs Repair

Posted by on March 4, 2021 in Stuff with 0 Comments

Our air conditioning systems work tirelessly to keep our homes comfortable and cool all through the hot season. Most times we even forget that it is there because we have become accustomed to the comfort that it offers.

Sometimes, we need AC repair on days when it hurts the most.  You won’t see it coming until you realize that you have lost a simple daily comfort. So, you need to ensure that the unit is always functioning properly. But how would you know when it needs maintenance or repair?

The following are signs that show your AC needs repair:

1. It Circulates Warm Air

The moment your unit starts blowing warm air through its vents, you may want to look at the thermostat. Make sure that is set to cool, then set it to a temperature that is lower than that of your home. If the warm air keeps circulating after this, the problem could be from the compressor or there could be a restricted airflow.

A cooling system can be quite complex; thus, it needs careful calibration. Instead of settling to fix it by yourself, it would be better to get a professional to repair it.

2. There is Insufficient Airflow

Generally, when the airflow is poor, it’s a sign that the AC unit is not working efficiently. It could also be that something is obstructing the air from flowing through the ductwork in your home. The usual culprits include clogged air filter and broken motors; it could also be something else that may be more serious.

Furthermore, if poor airflow becomes a common problem for you, you may consider getting a ventilator that supports energy recovery. It can boost the AC by supplying fresh air in exchange for stale air each time the system cycles.

Also, your air conditioning system may benefit from the zoning system in your area. This would ensure that it is getting the proper airflow as well as cooling power when needed the most. You may want to visit to read more about the causes of poor airflow from the ducts.

3. Frequent Cycles

An AC is expected to go through cooling cycles routinely, irrespective of the weather condition. On extremely hot days, the system may turn on frequently, but it should not turn off and on constantly. So, if you discover that the system has frequent cycles, you have to contact a cooling expert. A quick tune-up of the AC could resolve the frequent cycles, but it could also be a sign that your AC needs a replacement.

4. The Humidity Level Is High

During the summer and spring, the weather outdoors is sticky. But that does not mean your indoor humidity should be high. Your cooling unit is expected to automatically regulate the level of humidity.

However, if your cooling unit can no longer regulate the moisture level, you need to contact an AC repairer. They will carefully find out what the problem is and tell you whether the system requires re-calibration. You may even have to get a dehumidifier for the entire building.

5. The AC Leaks Water While Running

Your air conditioner cools using a refrigerant. This may produce some condensation while the unit is operating. No part of the liquids should leak or pool anywhere in your home. Therefore, a constant leak or pooling of water around the unit is an indication that the system isn’t operating optimally.

In this case, you should not waste time in calling an AC service technician. Leaks could damage your property quickly and could even result in serious structural problems.

6. The Unit is Producing a Bad Odor

If there is an unpleasant odor in your apartment and you suspect that it is coming from the HVAC system, you will want to tackle the problem before it gets smellier. An AC repairer will do a quick diagnosis and tell you whether your cooling unit will be fine with a simple tune-up or a thorough cleaning session.

If that is not the case, they will proffer a high-level tech solution. The use of UV (ultraviolet) lamps could help to eliminate the persistent growth of microorganisms in the unit. Also, cleaning the air ducts could resolve the bad odor that has accumulated inside the ductwork.

7. You Can Hear Unusual Noises in the Unit

Most AC units make noise at a low level when they shut down and start-up. But when you start hearing a loud, sudden, and unusual noise, it could mean that system is faulty.

Rattling or buzzing noises are an indication of parts that are loose while whistling or grinding noises are indicative of a more serious problem. Issues such as these will not self-resolve, therefore, an expert has to tune-up the entire system.

How You Can Help to Keep Your AC Cool

It is the work of your air conditioner to keep your apartment cool, but you could help, too. If the indoor temperature was extremely hot before you turned on the AC, it will work very hard to reduce it in order to restore comfort to your home.

Therefore, during the daytime, you should keep shades and blinds closed. This will help to keep the indoor temperature at a normal level. So, when you turn on the AC, it will not need to work hard to cool your home and the lifespan will be extended.

Other things you could do to help your air conditioner are:

  • Sealing up any air leak
  • Improving insulation
  • Creating wind-chill effects by using floor fans or ceiling fans
