Air conditioning units are the unsung heroes of our homes and workplaces, especially during the sweltering summer months. Their constant hum in the background keeps us cool and comfortable. However, like any other piece of equipment, air conditioners are not immune to malfunctions.
This blog post will explore the world of common air conditioning issues, offering you a comprehensive guide to troubleshooting these problems. For example, have you ever noticed your air conditioner blowing warm air instead of cold or creating unusual noises? How about leaking water or just not turning on at all?
By the end of this post, you’ll better understand your AC unit and how to keep it running smoothly all summer long. For an in-depth look at the reasons your AC fan keeps running, click the following link provided by Hurliman.

Common AC issues and how to fix them
The following list will delve into the most frequently encountered air conditioning issues, outlining their causes, how to diagnose them, and the recommended solutions or steps to rectify them.
1. Air conditioner blowing warm air
This issue can occur due to dirty air filters obstructing the airflow, a lack of refrigerant, or incorrectly setting the thermostat. Start by checking your thermostat and ensure it’s set to “cool.” If that doesn’t resolve the problem, inspect your air filters. If they are clogged or dirty, clean or replace them. If you still experience issues, consult an HVAC professional, as you might have a refrigerant leak.
2. Unusual noises
If your AC is making squealing, grinding, or rattling noises, it might be due to a loose part, a motor issue, or problems with the fan. First, switch off your AC to prevent any further damage. For minor problems like a loose screw, you may be able to fix it yourself. However, it’s best to call an HVAC technician for more serious issues.
3. Frozen evaporator coil
When faced with a frozen evaporator coil, start by turning off your air conditioning unit to allow the coil to defrost. This can take a few hours, so patience is key at this stage. Meanwhile, check your air filters. If they are dirty, replace them immediately, as they could be restricting airflow and causing the coil to freeze.
Once the unit is defrosted, turn it back on. If it starts to function normally, the issue might have been minor and temporary. However, if the coil freezes again, this indicates a deeper issue. It might be because of a refrigerant leak or a problem with the blower fan.
4. Water leaks
Air conditioner drain lines that remove condensation may become blocked with dirt and dust, causing water to collect inside or leak out under the unit into a pan or onto the floor. If this occurs, excess moisture could build up within your unit or may overflow onto it from underneath, potentially leading to overheating problems or flooding the room entirely.
If you find any standing water, immediately turn off your air conditioning unit and clean up any mess to prevent further damage. If the problem seems more significant, call an AC technician with the tools necessary to remedy the problem.
5. Unlevel thermostat
If your air conditioner appears to switch on and off constantly or is running constantly, this could indicate an unbalanced thermostat. First, make sure your power and batteries are operational; also, ensure it is free of debris (use a toothbrush to gently scrub internal components such as the anticipator).
Try moving the thermostat away from heat sources or direct sunlight, to ensure an accurate reading. If this doesn’t help, call an AC professional for a thorough inspection.
6. Tripped circuit breaker
Short circuits differ from overloads by tripping the breaker even without anything plugged in, signaling there may be an issue with an individual outlet or switch that poses fire risks if left untreated.
To address this problem, open up the breaker panel. Take note of which breaker is associated with the room in question and turn it completely off before plugging or switching on appliances and lights one at a time, pausing for several seconds between activations; if the breaker trips again, then this circuit has reached its limit and needs redistribution of load.
Troubleshooting the most common AC issues — Conclusion
Air conditioning units, though often overlooked, play a vital role in ensuring our comfort at home and work. As with any machinery, they are subject to occasional issues. By understanding the common problems outlined in this guide and their potential solutions, you are well-equipped to troubleshoot minor difficulties.
Remember, some problems may require professional attention. In such instances, never hesitate to contact a reliable HVAC technician. Ensuring your AC unit functions smoothly keeps you cool during summer and extends your unit’s lifespan, offering you long-term savings.
