10 Common AC Problems You Should Know About


Air conditioning is an essential feature of most modern homes, providing a comfortable indoor climate in hot weather. However, it can be frustrating when it malfunctions or doesn’t work as expected. Understanding common air conditioning problems can help you identify issues and prevent them from becoming more severe. Here are 10 air conditioning problems you should know about.

1. NOT BLOWING COLD AIR

If you are experiencing a lack of cool air from your air conditioner, a few underlying issues could be the cause. You could have a low refrigerant level in the AC unit, possibly due to a refrigerant line leakage. Alternatively, a malfunctioning compressor could be the culprit. This can result from a blown a fuse or a defective electrical switch. If your air conditioner’s compressor isn’t operational, it won’t be able to properly circulate the refrigerant, resulting in a lack of cold air production.

Another potential issue could be that the evaporator coil in the AC is frozen; this can occur if the air filter is clogged or if the airflow around the evaporator coil is blocked. If the evaporator coil is frozen, it won’t be able to absorb heat from the air, thus preventing the AC from producing cold air.

2. LEAKING

Maintaining an air conditioner is essential to ensure it functions appropriately and prevents leaks. Clogging of the drain pan, which collects water removed from the air, is one of the most common causes of an air conditioner leak. If the drain pan is not regularly emptied, the water can overflow and begin to spill out.

Failure of the condensate pump is another cause of an air conditioning system leaking water. The condensate pump helps to get rid of water from the drain pan, and if it fails, the water will accumulate and eventually cause a leak. In some cases, a defective condensate pump can also lead to water backing up into your home, which can cause severe damage. If you spot your AC unit leaking water, get it serviced by a certified technician immediately.

3. TRIPPING THE CIRCUIT BREAKER

A circuit breaker is a safety device that trips when there is an overload of current in an electrical circuit. This prevents damage to the electrical system and keeps you from being electrocuted. If your AC trips the circuit breaker, too much current is running through the system. Several things, including a faulty compressor, a shortage in the wiring, or a problem with the air conditioner itself, can cause the tripping of a circuit breaker. If you suspect this is the problem, it’s recommended to call a qualified technician to come and take a look at it.

4. UNUSUAL ODOR COMING FROM THE UNIT

If you notice an unusual odor coming from your air conditioning unit, it could be a sign of a problem. The most common cause is a buildup of dirt and debris in the system. Other causes of an unusual odor from your air conditioner include:

  • Dirty coils
  • Leaking refrigerant
  • Mold or mildew growth

It’s essential to have any strange odor your air conditioner may emit checked out by a professional, even if the unit functions correctly in all other ways.

5. THERMOSTAT MALFUNCTION

Thermostat malfunction is a common issue among air conditioning systems. This can result in the temperature of the air conditioning system remaining higher than expected, making it difficult to cool the room. This sort of malfunction could be due to several causes, including a faulty thermostat, a malfunctioning air conditioner, or a lack of power to the thermostat.

If the thermostat is not working as it should, it is important to have it checked by a qualified technician to determine the reason. Sometimes, you may need to replace the thermostat or service the air conditioner. If the thermostat works correctly, you may need to adjust the temperature settings to a lower level. Once the thermostat is back to normal, the air conditioning system should return to its average temperature.

6. AC UNIT DOESN’T TURN ON

If your air conditioner is not functioning at all, there are a few potential issues you should look into. Begin by confirming that the electrical plug is connected and the power switch is on. After that, inspect your home’s circuit breaker or fuse box to ensure that the circuit for your air conditioner has not been tripped or blown. If it has, seek help from a certified HVAC technician.

7. CLOGGED AIR FILTER

A clogged air filter can cause a range of problems with your air conditioning equipment, including reduced airflow and circulation. A clogged air filter will reduce the amount of air that moves through the system and cause the compressor to work harder, reducing its efficiency and increasing the energy used to cool your home. It can also cause the evaporator coil to freeze, potentially leading to ice buildup.

In addition, a clogged air filter can lead to poor air quality in your home, as airborne pollutants are not properly filtered out. It is important to regularly change your air filter to ensure that your air conditioning system is working optimally and providing the best air quality possible.

8. FAULTY COMPRESSOR

The compressor is responsible for pumping refrigerant throughout the AC system, and if it fails, the entire system can shut down. Various issues, including a defective start capacitor, a bad motor, a clogged condenser, or a lack of lubrication, can cause a compressor failure. If the compressor is malfunctioning, it’s best to call a professional to inspect and fix the issue. Without the proper repair, the system may not be able to cool your home sufficiently, leading to more costly repairs in the future.

9. FAN PROBLEMS

Fan problems can range from a simple obstruction of the fan blades to a more serious electrical failure. One of the most common fan problems is a blockage or interference with the blades, which can cause the fan to be noisy and not move air as efficiently.

Another frequent issue is overheating, which can occur when the fan runs for extended periods. In addition, a damaged or worn-out motor can cause the fan to become unresponsive or to stop running altogether. It is important to check that the fan is connected to a properly grounded outlet to avoid the risk of electric shock. If any of these issues are present, it is best to call a professional to inspect and repair the fan.

10. FROZEN EVAPORATOR COIL

A frozen evaporator coil can be a serious issue for air conditioning units. Freezing happens when the evaporator coil cannot absorb enough heat from the air passing over it, causing it to freeze up. This can lead to a number of problems, including a decrease in cooling efficiency, water leaking onto the floor, and eventual system failure. To prevent this issue, it is important to keep the evaporator coil clean and free of debris. This will help ensure that the air can pass over it unimpeded and reduce the risk of freezing up.

My family has trusted Dragonfly for the last 10+ or so years and they haven’t disappointed. A couple years ago they’ve replaced my AC, relocated my water heater and installed a whole house fan. Each time they have come out, they have been professional, informative, helpful and kind. With each estimate I’ve requested, they have been timely and always have provided competitive pricing.They’re staff from the fabulous gals in the office, to Jeff who led the install, to their owners Sheldon and Barry really set them apart. Such an AMAZING and TRUSTWORTHY group. So so thankful!

I had my heater inspected and prepared for the winter ahead by Dragonfly HVAC company today. My technician was Austin, he is thorough and knowledgeable. He replaced my filter and cleaned some electrical connections in addition to testing my motors for amperage draw, and my capacitors for variance. In other words, my system is now ready to perform its work to keep my home comfortable and warm.

Drangonfly operates a business of integrity. They showed up 5 min early of the 4 hour window which was a good surprise. They diagnosed the problem in 5 min and went over our options. If you want a quality installer who will not deceive you, and relies on quality and word of mouth satisfaction, give them a try.

Dragonfly heating and cooling (used to be All Pro Air) is a great customer service and quality oriented company. We have used them numerous times to upgrade and maintain our home.First we used them to install an all house fan in the attic which is extremely useful in the summer months with cooler nights which saves us greatly on our electric bill!Then we used them to replace our entire ducting in our attic as certain rooms had limited to no airflow and would not cool down. They discovered some crushed ducts and we decided to replace it all. Good price, and even better customer service! When I called the next day saying there was still an imbalance between rooms, they sent one of their install managers who personally tweaked the ducts until it was just as we wanted it.Third we had our blower motor and wheel fail in an original furnace and decided to replace the furnace and coil (trouble in buying a 40 year home with original parts!). They came and installed professionally and provided us a temporary mobile cooler. The next day, the refrigerant line froze over so after calling they sent someone same day who changed the charge level to ensure we were good to go. A month later, our furnace started rattling even though it was working, and after calling they sent someone next day who then replaced blower wheel, identified issue, and made the configuration more efficient. Yes there have been minor issues, but the customer service is what makes them the top choice in the area. And their prices are honest and competitive.Their techs are also professional, friendly, and willing to answer all my HVAC questions. In every experience, they provided good service and were courteous to our home and property.Highly recommend and will use into the future for any HVAC needs we might need.

Trevor was great! We are looking around for estimates to replace our old ductwork (which is 20+ years old). Yesterday, Dragonfly sent Trevor out to do the estimate. Trevor was professional, friendly hard working and seemed very honest. It was almost like talking to a trusted friend. He wasnt in a hurry like many were to get in and out due to the heat (which I understand) but instead he took pride in his work by being thorough. He took pictures of our horrendous ductwork and educated us on our ducts and how they're supposed to be designed for efficiency (which ours are not). It was very refreshing to speak to an honest person working for an honest company. Its unfortunate but its not common. I mean he even offered to paint the covers to our access spaces because they had dirty finger prints. May God bless this company and their employees 🙏🏽

Yesterday on 7/26/24 my A/C completely stop blowing cool air. I immediately called the HVAC company that installed my new A/C in 2018 and was told they couldn’t make it out until Wednesday of next week. Therefore I went on “What’s up Corona” on Facebook to get recommendations on A/C repair. Dragonfly Heating & Cooling was recommended on so many Facebook posts that I went with them. I called and Lori was so helpful/courteous and had me booked for the very next morning. The temp in my home was at 89 and unbearable. This morning the HVAC Tech Josh was on time and diagnosed the problem and immediately fixed it. We had cool air in minutes. I’m one happy customer. Going forward I will call on Dragonfly Heating & Cooling if needed. Thank you

Straight shooters. My new heat pump system was installed professionally and works as advertised. From start to finish, Dragonfly Heating and Cooling did a good job.The diagnosis of my old system was straightforward and all of my options were explained. With the purchase of the new HVAC system, Dragonfly's representative threw in a new Wi-Fi thermostat and a great capacitor.The installation crew was on time, clean and professional. The new heat pump HVAC system was installed like clockwork. The installation manager arrived towards the end to troubleshoot and finish up. It works.Initially the invoice did not specify the system information. Dragonfly then met my documentation needs, to enable rebates from my utility company and on tax returns. Also having the invoice with full information will enable warranty claims, which I hope to never need.In sum, Dragonfly did a very professional job installing the new ACPro heatpump HVAC system. I sincerely appreciate it.
