Typical Cooling Problems You May Face This Summer

This article discusses the top ten air conditioner problems that homeowners tend to face during the summer weather.

1. Air Conditioner Is Not Turning On

If your air conditioner stops working abruptly, check to see if the circuit breaker tripped. Reset, replug, and replace the thermostat batteries if needed. If the problem continues, call an HVAC technician for assistance.

2. Air Conditioner Making Noises

Different air conditioner problems are indicated by different noises. For example, a buzzing noise indicates an electrical fault, while a hissing sound signifies a possible AC coolant leak. Keep in mind it is normal to hear a constant low hum. An experienced AC technician will be able to diagnose the AC problem just by hearing the noise.

3. The Outside Unit Of The Air Conditioner Is Frozen

The outside unit of an air conditioner can freeze for a number of reasons. For example, an AC refrigerant leak could cause the coolant to run low, or it could be very cold outdoors. It could also not have enough sufficient airflow or be an issue with the blower motor. Have a licensed HVAC technician look at the unit to find out what the problem is.

4. AC Refrigerant Leak

Refrigerant is a necessity for an air conditioner to work correctly. There can be lots of problems if it leaks. Some examples include uneven cooling, increased power consumption, freezing coils, or a damaged compressor. To prevent any of these issues, schedule regular air conditioner inspections.

5. Frozen Evaporator Coil

To prevent your air conditioner from freezing, make sure the evaporator coil has constant airflow. Check to see if there is anything blocking it. This could occur because of dirty HVAC air filters, clogged vents, or a broken fan. Clean your unit periodically to avoid this issue. Your air conditioner will require a tune-up on an annual basis.

6. Air Conditioner Not Blowing Cold Air

Air conditioners should easily be able to cool down your home. If they aren’t, check your air filter. If it’s clogged with dirt, then air can’t flow freely through the unit. To prevent this, check and replace the air filter as often as necessary.

7. AC Sensor Problem

An AC sensor’s job is to turn on or off the system, depending on the temperature. If it’s placed in the wrong spot, it will have faulty readings. Have a technician position and calibrate it in the right spot.

8. Electric Control Failure

Frequent cycling of air conditioners is not considered normal operation. It stresses the unit and increases wear and tear, especially to the compressor, the fan motor, and the blower. These components work best when running at a constant state. Frequent AC cycling may lead to electric control failure which will prevent these air conditioner parts from working as expected.

9. Air Conditioner Leaking Water Outside

Humid days cause condensation to form on the coils. Usually, moisture flows through drainage channels. However, a leak may occur if the drain channels are broken or blocked. This can happen because of incorrect installation, a broken condensate pan, or blocked drain pipes.

10. AC Drainage Problem

Bacteria and fungi can grow over time if there is stagnant water in the AC unit due to a drainage problem. Bad odors will take over your home which is not only unpleasant but also unhealthy. To prevent this issue, have regular inspections done by professionals.


Use These Steps To Prevent Air Conditioner Problems

1. Check The HVAC Filter

Changing your air filters regularly is the best way to avoid problems. It is recommended to replace your filters every one to three months, depending on your particular home. If you notice problems before this time, you should change it to be safe.


2. Clean The Condensing Unit

Dirty coils in the outdoor unit make for a less effective air conditioner. Clean it often and remove any leaves, twigs, or debris that has accumulated.

3. Make Sure That Nothing Is Blocking The HVAC Vents

Make sure there are no objects like curtains or furniture blocking the air vents. They should be open so air can flow easily.

4. Install A Programmable Thermostat

Install a programmable thermostat if you can. These thermostats tend to perform better than the manual versions. You can set them to your schedule and preferred temperature. This will help improve your AC unit and reduce energy consumption.
