4 Signs that You Need an Emergency AC Repair

Sharing is caring!


When the AC is comparatively older, it will require repair here and then. Without these repairs, your air conditioner won’t function properly, and its performance will decline. But unfortunately, many homeowners ignore these required AC repairs. Currently, if you’re facing the following issues, you must contact an HVAC professional ASAP. 


4 AC Repair Signs That You Shouldn’t Ignore 

  • Refrigerant or Water Leakage

Air conditioners use refrigerant or coolant to absorb the heat from the space. But due to leakage, this refrigerant level can drop and hamper the cooling process. If you find out that your cooling unit is leaking refrigerant or coolant, you should immediately call an air conditioner repair expert and check the unit professionally. 

Over time, air conditioners lose their efficiency and start to have internal damage, and this leads to refrigerant leaks. That’s why most homeowners with an older air conditioning unit face refrigerant leak issues. If you have a relatively older air conditioner and it is not cooling efficiently, it is likely that there is refrigerant leakage in your air conditioning system. 

Refrigerant is very toxic and harmful in nature. This is why you’ll have to be very cautious during the refrigerant leakage repair work and take help from a professional. A certified HVAC professional knows how to deal with refrigerant leakage and follows all the guidelines set by the EPA. As a result, you get the best AC refrigerant leakage repair. 

You should keep in mind that refrigerant leakage can be detrimental to you’re A/C unit. When there is a low level of AC refrigerant, it’ll make the cooling unit to run longer. As a result, there will be excess pressure on the cooling unit, and this will lead to more wear and tear. If you keep running you’re A/C in this condition, parts will become irreparable, and in the worst-case scenario, your cooling unit will shut down permanently. That’s why as soon as you notice refrigerant leakage, you should call an HVAC repair technician as soon as possible. 


If your air conditioner is still using the banned Freon as refrigerant, you should switch to the R-410A. This refrigerant is more environmentally friendly and easily available in most stores. 

  • Abnormal Sound Coming from the AC 

A well-functioning air conditioner makes white noise while it operates. However, you should call an HVAC repair expert immediately if it is making a buzzing or rattling noise. 

Usually, when a cooling unit makes abnormal noise during its operation, it indicates that there are some internal damages. Again, if it makes whistling noise, it indicates that there is a lack of airflow in the unit. The air conditioner can have this issue when the air filter is clogged or filled with dust. Also, if there are leaks in the air ducts, your AC won’t get enough air supply. 

If you install an oversized A/C, you can hear unusual noises too. An oversized AC unit will frequently cycle on and off, which will make the AC make unusual noises. Apart from the noise, when you install an oversized A/C, it’ll make the unit wear out quickly and reduce the lifespan of the system. This is why before purchasing an HVAC unit, consult an HVAC expert and install a right-sized AC.

  • Air Conditioner is Producing Hot Airflow 

Usually, when there is a problem with the thermostat, AC starts producing hot air instead of cold. 

A thermostat is considered the brain of a cooling system. But over time, this thermostat can start to malfunction and make the whole unit perform poorly. That is why you should check the unit professionally if your AC is producing hot air. 

Pro-Tip #2

Switch to a smart thermostat if your AC is still using a manual one. With this type of thermostat, you can schedule the temperature settings and save more energy. 

  • Not Getting Desired Cool Airflow from the AC 

The main purpose of an AC filter is to block foreign materials from entering the air conditioning unit. Because of this, it gets clogged quickly, and when it gets clogged, it blocks the airflow. 

When the airflow is blocked, your cooling unit won’t get the necessary air supply, and as a result, it won’t be able to produce enough cooling. That is why you must change the AC filter frequently. 

Usually, it is advised to change the AC filter after 3 months. However, if you live close to an industrial area or in a large city, you’ll have to change the air filter more often. To know the exact time of filter replacement, you should contact a local HVAC expert. Similarly, if the AC filter that you use is cleanable, you should clean it every 2-3 months. 

Pro-Tip #3 

If you want to boost indoor air quality, you should use HEPA air filters. These air filters can block most of the particles, such as dust, debris, bacteria, and pollens. However, before installing such a high-rated filter, you must check its compatibility.
