Air Conditioning Repair St. Charles
One of the most common air conditioning service problems is the result of the improper operation. This may sound like a no-brainer, but be sure to close your home's windows and outside doors. Running your air conditioner with even a single window or door partially open, or if you have an outdoor party with a lot of traffic going in and out of the house, means your cooling system is now working double time to produce enough airflow to cool your backyard and the neighbors too. Obviously, this puts a huge strain on your air conditioner and can lead to mechanical breakdowns and faulty operation.
Other common problems that can lead to damaging your air conditioner are faulty installations, poor service procedures, and inadequate maintenance. Improper installation of a central air conditioner can result in leaky ducts and low airflow. Often times, service techs do not put the proper amount of refrigerant in the air conditioning unit, not meeting the manufacturer's requirements, and resulting in poor performance and efficiency. Also, be mindful of unqualified service technicians who fail to discover refrigerant charging problems when inspecting your cooling system, or even worse, they contribute to the existing problem by adding refrigerant to a system that is already full.
If your air conditioner does not seem to be running properly or fails entirely, let the unit cool down for 10 to 15 minutes, then check any fuses or circuit breakers to see if they've tripped. Even it if does start to run again, it's a sound idea to call you cooling and heating service pro to inspect the unit in case you do have a larger issue.
For room air conditioning units, isolate the room or a group of connected rooms, as much as possible from the rest of your home. For a list of common air conditioner problems and what to look for, see more information on the Department Of Energy's website, or just review our list below.
The performance and efficiency of your air conditioner rely on having the proper amount of refrigerant in the system. Improper refrigerant levels could be caused by a service tech undercharging the unit during installation or you may have a leak. If it is leaking, simply adding refrigerant is not a solution since the leak was not repaired. A trained technician should fix any leak, test the repair, and then charge the system with the correct amount of refrigerant. Texas A&M University paper found that air conditioners decreased by 17% with just a 10% undercharge of refrigerant (freon).
Your air conditioning system requires constant, unblocked airflow. Neglecting to change filters on a regular basis or allow air conditioning coils to become dirty, could cause the compressor or fans to fail prematurely. An interesting fact: The Applied Building Science Center reports "the average air conditioner operates at 40% less than the efficiency rating - the reason was poor technician training and lack of maintenance.
Electric Control Failure
Compressor and fan controls can wear out over time, especially if the air conditioner is frequently turning on and off, as is common when a system is oversized. Electrical connections and contacts can also corrode over time and should be checked regularly by a service professional.
Thermostat Sensor Problems
If a room air conditioning unit's thermostat sensor is knocked out of position, the air conditioner could cycle constantly or behave erratically. Ask your service tech about this being a possible issue if your room AC unit starts acting up.
When it's humid outside, regularly check the condensate drain to make sure it's not clogged and is draining properly. Also, if you have a room air-conditioning unit, check to see that it is draining properly as well. If not, it could be the result of it not being mounted properly and not being level.
