While many problems with air conditioning will require a professional technician to repair them, we found that sometimes a homeowner can fix simple problems with a little troubleshooting. Therefore, the same motor, fan and ducts used for heating are used to distribute the cold air of the air conditioning system. The hot air is moved by the fan through the cooled evaporator coil in the distribution chamber and is then supplied through ducts to cool the house. If the air conditioner expels cold air but doesn't cool the house, there could be a leak in the house to the outside.
You need to also include working with an expert rain gutter cleaning company such as Gutter Cleaning Charlotte NC to see to it that your gutters are working well which is to maintain away the water from your house. This excess water is caused by clogged-up water, so rather than the water draining well, it will just go on overflowing which may create water damage to your house's air conditioning.
Air conditioners work in part by removing moisture from the air (through condensation), and that moisture must go somewhere. Reduced airflow, whether caused by dirty filters, a dirty coil, a dirty squirrel cage fan, or a broken fan motor, can cause the coil to freeze and obstruct air flow. If the air you blow is hot or there are loud noises or vibrations when you start the air conditioner, the compressor may be breaking down. Air conditioning and HVAC units don't last forever (12 years is an average lifespan) and the time they fail is usually when you need them most.
When the air conditioner works but the house doesn't cool down, the problem is probably in the distribution system. You must clean the coil on the intake side, so before disconnecting the power to the air conditioner, check in which direction the air moves through the coils. When a central air conditioner is operating, warm air from inside the house flows to the oven through the air return duct. Follow the instructions above in the Air conditioner that does not blow air section and consult the owner's manual.
If you can hear the air conditioner working but it's not blowing air, see the article Air conditioner that doesn't blow air. When the switch is set to “Automatic”, the thermostat turns on the air conditioner when the interior temperature exceeds the desired preset temperature.
