Nine Most Common Air Conditioning Problems

In these tough economic times, the last thing you need is a great air conditioning repair. Although all mechanical systems require periodic repairs, many breakdowns can be avoided. Here are the nine most common problems we face every spring and what you can do to avoid them.

1. Dirty Filter

If you have a single-use 1-inch filter, you’ll need to change it every month. It’s out of sight and memory, so it’s easy to forget to change it. However, every year we go where the air conditioner is not cold, and this is due to the limited airflow from the too dirty filter. Dirty filters reduce indoor air quality, make homes less comfortable, and cause indoor circuits to freeze up, leading to serious problems to fix.

2. Turn off the power

Some heating and air conditioning systems are equipped with an indoor unit wall switch which can be mistaken for a light switch for safety and convenience. If you accidentally turn it off or leave it on in hot weather, your air conditioner won’t turn on. Always check the status of the change before calling us.

3. Breaker has been tripped

One of the most common reasons for calls not cooling is that the key is disabled. Please return it before calling us. We hope this will not happen again. If so, call us. Something caused the switch to shut off. It’s usually something as simple as a bad switch, loose wire, or bad capacitor. However, if left unchecked, some simple problems can lead to much more expensive repairs.

4. Coolant leak

The air conditioner is an airtight system. The refrigerant must never leak. When that happens, bad things happen. The performance of your air conditioner will decrease, and electricity consumption will increase. Your air conditioner may not be cooling. The winding may be frozen. The compressor may be damaged. In addition, refrigerants are greenhouse gases. We use various tools to detect refrigerant leaks. The problem is often as simple as a faulty Schrader valve or a bad connection between the connecting pipe and the coolant pipe.

5. Thermostat

Some thermostats need to switch between heating and cooling modes. If the switch is in the wrong position or damaged, your air conditioner will not start. High-quality digital thermostats are rarely thrown away. Some inexpensive varieties may be available in large boxes. So what’s going on? The switch may be damaged, and voltage spikes can cause malfunctions, etc.

6. Clogged drainage pipe

Remove the air conditioners from the humid air and, at the same time, lower the temperature. Moisture is usually removed from your home by plumbing. The secondary condensate leak should be a leak. Algae in these rows can grow by blocking them. This can cause water damage to your home. We drain the sewer pipes as part of our spring air conditioning, or you can do it separately if needed.

7. Contactors

The contactor is the electromechanical switch on your air conditioner. Sometimes the silver cap of the contactor wears out, և the contactor gets stuck, which allows the peripherals to work continuously, which is expensive. Sometimes ants are attracted to electricity, “pushed between the contactors,” which prevents them from closing. If this happens, the external device will not work. The contactors may also be electrically damaged. We check them during spring tuning; if necessary, clean the contactor surface, and recommend replacing them for damage.

8. Dirty evaporating radiator

The coil must be cleaned regularly; otherwise, dust & dirt will accumulate, limiting the coil’s heat exchange capacity & reduce airflow to the system. Dirty places increase operating costs & reduce the comfort of your home.

9. Dirty capacitor winding

The condenser coil is located outside the air conditioner. A dirty or limited coil is inefficient, increases energy consumption, and reduces system cooling capacity. Maintaining cleanliness reduces energy costs & use of the air conditioner.

How To Identify The Best Air Conditioner For You

Air conditioners make the home comfortable to live in even on the hottest or coldest days of the year, and some people find it hard to live without one. So how does someone know the best air conditioners for their homes?

There are obvious factors like budget, type of house, and the size of the house. However, there are other factors like how flexible the air conditioner can be, how many brooms it can cool or warm at once, how it looks inside the home, the carbon footprint of the conditioner, and how much energy it consumes.

There are different air conditioners, and each has its advantages and disadvantages. Here is some info we obtained from a local Las Vegas AC repair company that might help out your decision on which type to select:

Ductless Mini Split AC

The ductless mini-split air conditioner is a big air conditioner, which remains in sight in the room where it is installed. It offers the owner the convenience of controlling different room temperatures rather than relying on a central thermostat.  It is easier to install as it only requires a small hole drilled into the wall. The absence of ductwork is probably the highest advantage as it improves air quality. The air does not have a chance of collecting any dust from the ducts, and neither does it warm up as it travels to the home.
Ductless air conditioners are best for people who;

  • Care about the environment and energy efficiency.
  • Do not mind having a big box on their walls.
  • Do not want to have ducts in their walls.
  • Want to heat new spaces not convenient for existing central air.

Ducted or Central Air Conditioners

They provide cooling or heating via ducts installed all over the home, making it impossible for installation into old structures. The central unit, which has the compressor, condenser, and an air handling unit, is located outside the house, in the garage or basement.

Air from the compressor then travels through the ducts into the house via discretely installed vents and ducts either directly mounted onto the wall or as a compact floor-standing unit. They are costly to install because of the duct installation.

Ducted air conditioners eliminate humidity in the air, and they are perfect for large houses or commercial rooms. The main disadvantage with this type of air conditioning system is that there can be an accumulation of dust ad mold on the ducts, compromising the air quality. They also need a lot of maintenance.

Owners can use two types of ducting to install this system. Flexible ducting consists of tube-like structures made from a metal framework with flexible insulation and plastic around them.

It is easier to install and cheaper. It is best for small spaces or at the end of rigid ducting to connect it with the air outlet. Rigid ducting is done with study ducts made of metal, which makes them harder to install.

Split air conditioners are types of ducted air conditioners made for individual areas in a home like a bedroom or the sitting room. They are economical as the owner will only buy one unit at a time, and it also consumes less energy.

They also allow the owner to select the rooms they want air-conditioned. It is also efficient when air conditioning compact spaces.

Multi-split air conditioners are another type of ducted air conditioners, which allows the owner to run different air conditioners giving independent temperature control in every room for up to five rooms.

The owner can also choose different indoor units for different rooms like wall-mounted, floor-standing, duct connected, or castle type units. Central or ducted air conditioning systems are best for people who;

  • Are constructing new houses or completely remodeling their old homes.
  • Want invisible cooling systems.
  • Do not mind spending a lot of money.

Window Air Conditioners

They are a perfect option for renters because they do not need any holes cut into the wall, and it is not a permanent system. The compressor, expansion valve, and condenser are in one box, found outside the window.

There are louvered vents inside the window, where the cold air from outside comes through, which are not easily spotted. Heavier window air conditioners need extra support for them to remain hanging outside the window. They are best for people who;

  • Have windows that open horizontally.
  • Want to control the temperatures of small rooms.
  • Move a lot, or cannot modify their houses.
  • Do not mind the vibration or noise it produces.
  • Want a more stylish look in their home.
  • Strong enough to bring it up and down.

Portable Air Conditioners


Although they are not as efficient as window units, they are suitable for people who move a lot and do not want the heavy air conditioner weighing them down. They are easier to move with as they are light and have wheels.

They are also suitable for people who do not have a window to install the window air conditioner. They have a venting kit connected to hoses, allowing hot air to vent out via a casement window or a sliding door and cold air to vent in.

For a portable air conditioner, owners have to choose between dual or single hose systems. Single hose systems pump hot air out of the room using one tube, which reduces the room’s air pressure. That can cause more hot air from the outside to come into the room through the window, doors, or cracks.

Dual-hose portable units suck in the hot air from the room and cool it, then release it back into the room. There is a second intake hose that pumps in cold air from the outside into the unit and pumps it back out to prevent the system from overheating.

That ensures that the unit is not overworking, ensuring its efficiency. They can cool a larger room than the single-hose portable units.

Owners can choose the color they see that will blend perfectly with their home decors. They are perfect for people who;

  • Can’t modify a building or renters.
  • Want a stylish look in their homes.
  • Have sliding doors or casement windows rather than sash windows.

Owners have to consider the air conditioners’ fan settings to ensure that they have multiple fan speeds. Also, there are convenience features like remote controls and energy-saving features that good air conditioners should have.
