The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%.
According to a 2015 government survey, 87% of the homes in the United States use air conditioning and 65% of those homes have central air conditioning. Most of the homes with central air conditioning have programmable thermostats, but approximately two-thirds of the homes with central air do not use this feature to make their homes more energy efficient.
Because an air conditioner moves heat between the indoor coil and the outdoor coil, both must be kept clean. This means that, in addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condenser coil. Failure to keep the condenser clean will eventually result in harm to the compressor, because the condenser coil is responsible for discharging both the indoor heat (as picked up by the evaporator) and the heat generated by the electric motor driving the compressor.
The myth that most people believe is that if you add more refrigerant to the unit it will cool better. This is only true if the evaporator coil is operating below freezing. The unit must have a balanced charge at the correct refrigerant pressure for the temperature and usually, only an HVAC professional can charge your unit properly. Another misconception about refrigerant is that the unit burns it up and it must be replaced from time to time. This is not true. Furthermore, the refrigerant loop is a closed system and barring any leaks the air conditioning system should never need any refrigerant.
With winter on its way back to Atlanta, furnace and heating repair may not be the first thing you think about, but maybe it should be. Sure, it’s easy for us to sit here and tell you to arrange annual furnace service, but it’s only because we want to help you avoid a heating breakdown during the coldest day of the month in Atlanta. Day or night, our HVAC experts are here to ensure you have a comfortable home, and can help get your furnace back operating in almost no time.
The most common signs that the air conditioning unit may soon break down include loud or strange noises coming from the unit or warmer than normal air being released. In addition, if your unit smells bad, is frosty or water is leaking, chances are, you’re in need of repair. When the air conditioning unit displays these symptoms, contact a local HVAC pro. Just like a low tank of gas, it’s better to gas now versus running out in the middle of a 95-degree July afternoon.
Its difficult to describe how good of an experience I had with Cobb heat and AC. Ill put it like this, I have gone two 3 other AC repair companies, they send out their most novice field engineer, they give me a 6000 dollar quote to replace my AC for a property I just purchased, and then they leave. Mr Cobb came out himself, figured out the issue cleaned the condenser coils and told me my unit was only a YEAR OLD!!! He did not try to up-sale me or BS me with a quote to replace the boiler which I have had happen as well as the ac unit. Other AC companies suck, I'm sticking with Cobb. hope that helps

When central air conditioning service fails during a heat spell, you may have to wait days for an HVAC repair technician or a ac contractor to show up, and you’ll probably pay at least several hundred for the repair. But if you’re comfortable working around electricity and are willing to spend about $50 on parts, you can probably repair your air conditioning service yourself in about two hours and save about $225 on parts markup and labor.
