Faulty AC units can be a big pain especially if you live in a hot environment. In many cases, people have to call technicians to diagnose the situation. However, in this article, we’ll be giving you the most common causes of AC problems and how to prevent them.
Common Causes of AC Problems
Certain problems and conditions can cause you air conditioning unit to malfunction. Here are some of the most common causes of this:
Grimy Condenser Coils
Condenser coils are located in an AC system’s outdoor unit. These coils are responsible for expelling heat outside a building. Over time, these coils can get covered in grime and dirt. This makes it difficult for the unit to work. This in turn could lead to the system overworking and failing.

The moisture expelled by the AC is converted to water. This water has to be drained; that’s why the outdoor units of air conditioners have a hose attached. If this hose is blocked, the water will build up and eventually damage the unit. If care isn’t taken, water could damage various parts of your house and eventually lead to mold development.
AC’s Evaporator Coils Frozen
Condenser coils and evaporator coils are a bit similar. However, it’s important that you don’t mix these two up. Unlike condenser coils, evaporator coils are found in the system’s indoor unit.
These coils are full of refrigerant which help the system absorb heat from an environment. Strange as it may seem, these coils require warm air in order to function properly. If the evaporator coils get too cold, ice will start forming. This will make it difficult for the system to produce cool air.
We’ve talked a bit about refrigerant before. This helps remove humidity and heat from an environment. If an AC system has a leak in its refrigerant line, it will reduce the unit’s capability to make the air cooler.
An AC system has two fans. One removes heat from a building by blowing the air over the condenser coils. The other one blows air on the evaporator coils in order to make the air cooler.
If any of these fans gets faulty, it will lead to airflow problems. This, in turn, could cause the compressor to break down.
Preventing Air Conditioner Problems
While most air conditioner problems can be fixed, it’s always better to prevent them. Here are some simple steps you can take to do this:
Fix Any Holes In AC Ducts
From time to time, you should hire an HVAC technician to take a look at your unit’s ducts. This will help prevent the development of any future problems.
Clean Air Filters
You can do this one by yourself. Depending on your air conditioner’s model, the air filter will be located in the front or top of the indoor unit. You can wash the filter with water and dry it. This will improve airflow and prevent the evaporator coils from freezing over. Click here to learn more.
Service The System Regularly
It’s important for you to call an HVAC technician from time to time to service the whole AC. It’s not as expensive as some might think. This will keep the system in good condition and save you some good money on the long run.
Common Thermostat Problems and Solutions
Here are a couple of the most common problems that thermostats have:
Thermostat Switches Temperature By Itself
To some people, this might not be a big deal. Sometimes your thermostat may reduce cooling or heating based on its own estimation. However, the user might not be happy with the temperature change. To fix this, simply turn the safety switch off. This will prevent the thermostat from working automatically.
Thermostat Suddenly Goes Blank
This is definitely the most annoying problem a thermostat can have. Sometimes a thermostat goes blank without any error or warning. In most cases, this is caused by the thermostat’s wiring getting tangled. This may occur if repair work has been done on the wires. Unfortunately, you can’t fix this problem by yourself.

Air conditioners develop problems from time to time; there’s no surprise there. However, it doesn’t make it any less annoying. There are certain issues you can fix by yourself. You only need a few tools and a lot of courage. You also need to remember that there are certain problems that require expert handling. In such cases, you should hire experienced HVAC technicians.
