1. LOW COOLANT.
Refrigerant is what your air conditioner uses to remove heat and moisture from the air in your home or business. If the system leaks from the coolant pipes, you may not have enough coolant to cool the air efficiently. Fixing this air conditioning problem is unfortunately not just about replacing the coolant. A plumbing repair technician must locate the leaks and repair the holes in the pipes, which can sometimes be a long and costly process, especially if there are multiple leaks.
Vaporizer coils. The evaporator coil in your air conditioner is filled with coolant and is responsible for absorbing heat from the air like a sponge. It may seem counterintuitive, but these coils need hot air to circulate around them to function properly. If something goes wrong with the air flow and the evaporator battery becomes too cold, an ice layer can be built up on the outside. When this happens, you get either hot air or nothing at all from the air conditioning.
3. DIRTY CAPACITY COILS.
The condenser coils of the unit, which are part of the outdoor unit, dissipate the heat that is drawn out of the air by directing it outwards. The capacitor coil will not work well if it is covered with a layer of dirt and grime. This is a very common problem in New York with all this soot and air pollution. When this happens, the heat transfer is inhibited and the unit has to work harder, resulting in increased wear on parts and even system faults.
4. FAN PROBLEMS.
If any of these fans do not work, due to a broken engine, lack of lubrication, worn belts or too much dirt and debris, you will have poor airflow and problems with the air conditioning. Neglecting the problem can lead to compressor failure, which is often the death knell for your air conditioning.
Ducts that pass through walls and ceilings transport cold air from the air conditioner through the room. But if there are holes or breaks in your ducts (which can be caused by rodents or careless workers), this cold, expensive air will penetrate your walls where it will be of no use to anyone. And of course, this scenario will make the air conditioner work harder and increase the energy bill.
6. THERMOSTAT PROBLEM.
Especially if you still have the old rotary knob thermostats, they may be incorrectly calibrated, which means that your air conditioner does not receive the correct instructions from the control unit. This problem is relatively easy to solve by replacing or recalibrating the thermostats. When you have new programmable thermostats, they are sometimes difficult to program and can be set incorrectly. If you still have the operating instructions, check the instructions to ensure that the thermostat setting is correct.
7. USE Clogged.
All the moisture that your air conditioner draws out of the air must go somewhere. It is supposed to be taken out of the room through a drain pipe, to a pot and finally into a drain. If the pipes or drains become clogged, or if the container is full, water can collect and damage the system. Water leaks can also damage walls, ceilings and furniture. If you do not see it right away, it will eventually get mold.
