If you don’t have a good air conditioner, summers can be tough. Before summer begins, make sure your cooling system is working properly. Although extremely reliable, like all machines, they break down from time to time. By being aware of typical air conditioner problems and their remedies, you can have a comfortable, stress-free summer.

Typical Cooling Problems You May Face This Summer

The most common air conditioning issues are listed below:

1. Air Conditioner Making Noises

It’s typical for air conditioners to produce a low hum, but any other noises are a cause for concern. Each noise indicates a specific problem. For example, a buzzing sound likely is from an electrical fault. While a hissing sound indicates an AC refrigerant leak. An experienced HVAC technician will be able to diagnose the problem based on the sounds that your unit is making.

2. Air Conditioner Does Not Turn On

If your AC is not turning on, the circuit breaker may have tripped, causing it to be unresponsive. Reset if necessary and check to see if the plug is loose. Also, check and replace the thermostat batteries. If these steps don’t seem to work, contact a licensed HVAC technician.

3. AC Refrigerant Leak

Your AC unit relies on refrigerant to perform efficiently and correctly. If it leaks, cooling will be unequal throughout the house, power consumption will increase, coils will freeze, and the compressor might break. To avoid AC refrigerant leaks, schedule an inspection to be performed regularly.

4. Air Conditioner Does Not Blow Cold Air

If your central air conditioner is not cooling your house, look to see if the air filter is clogged with dirt. Dirt prevents the air from flowing properly. Also, the condenser can freeze. This decreases the cooling of the system. Replace your filter often to avoid this.

5. Air Conditioner Freezing Up Outside Unit

For this to happen, the coolant may be running low due to a leak or the temperature outside could be falling. There could also be a lack of airflow or an issue with the blower motor or a lack of sufficient airflow. To find out what the problem is, call a technician to take a look at the unit.

6. Air Conditioner Leaking Water

On humid days it is common for condensation to build up in the coils. Any moisture should flow out of the unit through the drain channels, but if they are broken or blocked, a leak can occur. This can happen due to a broken condensate pan, incorrect installation, or blocked drain pipes.

7. Frozen Evaporator Coil

To avoid freezing, the evaporator coil needs constant airflow. If you run into a frozen coil, check for any blockage from clogged vents, dirty air filters, or a broken fan. Regular AC maintenance and cleaning will prevent this from happening.

8. Sensor Problem


It’s important that your thermostat sensor is placed in the correct spot. If it is not, it can have false readings. An HVAC technician can fix its position and calibrate it.

9. AC Electric Control Failure

Air conditioners perform their best at a constant state. Wear and tear can easily occur if it is cycling frequently. Electric control failure may happen as well if the fan motor and blower motor controls are not working properly.

10. AC Unit Drainage Problem

Inadequate drainage causes water to sit inside the AC unit which often creates bacteria and fungi. With time, foul odors will spread through the house which is unhealthy and unpleasant. Regular professional inspections and maintenance will prevent this problem.

Simple Steps To Prevent Air Conditioner Problems

1. Check The HVAC Filter

It’s good practice to replace your air filters regularly since a lot of issues occur from a dirty filter. Replace it once about once every one to three months. If you notice the filter is clogged sooner than that, replace it even if it’s before the scheduled date.

2. Clean The Condensing Unit

Dirty coils in the outdoor unit are not very effective at transferring heat outside. To fix this, clean it periodically and remove any leaves, twigs, and trash.

3. Make Sure That Nothing Is Blocking The Vents

Poor airflow can be caused by objects blocking vents like curtains, furniture, and other items. Be aware of these spots and be ready to fix any problems so the air can flow freely.

4. Install A Programmable Thermostat

Replace your thermostats with ones that have better performance and calibration. If you can, get a programmable thermostat, so you can set the timers to your schedule and preferred temperature. Doing this will improve precision and reduce energy consumption.


The best way to avoid a broken cooling system is to proactively monitor and clean it. Homeowners should have maintenance and inspections done by HVAC professionals regularly. Only skilled experts can determine the problem and fix it right away for reasonable rates and great results.

Summer is here, which means that the days are getting hotter. Air conditioners are essential for beating the heat. Unfortunately, not all AC systems will function like they are supposed to. Some might perform in a way that will irritate the owners. If this is your situation, you may need to repair your AC unit or even replace it, depending on how bad the problem is. Time is of the essence when it comes to fixing the problem. Usually, it is easier to fix an air conditioner problem when it first starts happening. However, there are telltale signs that indicate that you have reached the end of your air conditioner life expectancy. An experienced HVAC technician can assess the issue and offer practical solutions.

Signs Your Air Conditioner Needs An Upgrade

These are a few examples of what might be wrong with your AC unit:

Your AC Does Not Blow Cool Air

An air conditioning unit should be able to emit cool air into your space. If the air coming out is warm, there could be a few issues going on. Firstly, you should check to make sure that the thermostat is working properly and that the unit is in cooling mode. Try changing the settings to see if the unit responds to the changes. If you set the temperature lower, your unit should start producing cooler air. If that doesn’t work, have a look at the air filter to see how clean it is. If the problem still persists, a technician can help you identify whether the compressor is the problem.

High Electricity Bill

Air conditioners tend to use up a large amount of energy, so your utility bills will probably be higher this time of year. However, if you see a sudden spike in costs, it may be time to investigate. Unless the utility company has raised the rates, your AC unit may be working inefficiently. There could be something preventing it from functioning normally. The problem could be forcing the unit to work harder, which will eat up more energy. Some common issues could be obstructed HVAC filters and AC refrigerant leaks. If the coolant is leaking, you should call in a professional.

Excessive Air Conditioner Repairs

A good air conditioner should be dependable. It is rare that an AC unit has issues or stops working, especially in the beginning. Problems usually start happening much later, around 10 years or so, because of natural wear and tear on the machine. Once the problems start, they usually accumulate. Constant repairs can be very costly, so it may be in your best interest to replace the unit entirely. A reputable HVAC professional can assess the situation and help you decide what is best for you.

Low Air Conditioner Airflow

If your air conditioner is not emitting the normal amount of air, it may be a sign that something is not working efficiently. There are a few issues that might be causing poor airflow. Some include a clogged HVAC air filter or a broken-down motor. These problems will need to be fixed as soon as possible to allow the unit to function properly. One way to increase your unit’s efficiency is to use zoning systems.

Increase In AC Cycles

When an air conditioner is functioning properly, it will cycle fairly consistently. If you notice that your AC unit is cycling more than usual, it could be a sign that there is a problem with the machine. Often this can be solved with a professional tune-up. However, if you notice that your air conditioner has been making many cycles right from the start, then the system may be oversized, which would require a replacement. A trained HVAC professional can assess your home to see what AC unit size will work best for that particular area.

Increased Humidity

Air conditioners not only cool the air, but they also help control the humidity. This is why it feels so good to step into an air-conditioned room after you have spent time outside in the heat. However, if you step into a room where the AC is not properly decreasing humidity, you will probably feel clammy and uncomfortable. If this is the case, you might want to call in a professional HVAC specialist to repair and recalibrate the machine. Another option is to install a whole-house dehumidifier to bring the humidity levels down. Your HVAC technician can help you make an informed decision.

Your Air Conditioner Leaks Water

An air conditioner decreases humidity by bringing the temperature of the air down around the coils so that condensation happens. This liquid collects in a container and is pushed out of the system to create cool air. If there is a problem within this system, the condensation may leak out of the unit. This could eventually cause problems to your walls or floors. An HVAC specialist can make the necessary repairs to prevent this from happening.

Your AC Unit Produces Unpleasant Odors

When moisture builds up inside the A/C unit, it can result in bacteria and pathogens growing. If this is not addressed, you might notice that the AC unit is emitting unpleasant odors. This can affect the comfort levels in your house and be offensive for you and your guests. The problem needs to be dealt with as soon as possible. Otherwise, it will get worse. An AC technician can tune-up the machine and give it a thorough cleaning along with the ducts throughout the house. Another solution could be to install UV lamps.

Strange Air Conditioning Sounds

Most AC units produce a low hum, but loud noises that come on suddenly are out of the ordinary and could signify a problem. If you hear rattling noises, it could mean that there are loose parts in the machine. A grinding noise could be a sign of a broken compressor. A technician can assess the problem to find the proper solution. At the very least, the unit probably requires a tune-up.

Most problems with air conditioners require the skills of a licensed technician. It is always best to call a professional to make sure you are properly maintaining your AC unit. A specialist will know whether the cooling system problems can be fixed or if it makes more economic sense to replace the unit entirely.
