After getting your best look at the air flow from the coil the next thing you are going to want to check is going to be the outside unit. Nothing means more to your air conditioning inside of your home than the outside unit. With out an outside unit working properly you will never have cold air moving throughout your home or office. Getting your home air conditioning running well can be the blame of how dirty the condenser is outside most of the time. Now when your air conditioning system is on top of the roof in light commercial situations that is when you wont have to worry about getting your outside unit cleaned as often. With the rest of the ground dwelling air conditioning and heating systems within the Richardson area they will have to be washed down very good before you get started in the spring with using the air conditioning system that much.
With a clean air conditioning condenser you will be able to get your electric bill back to where it was when your air conditioning system was new. The best part about having your outside unit cleaned on your AC system is to get the house or business to cool down faster. With more air flowing across the condenser coils that means more freon is getting condensed down into liquid.
Nothing about cleaning the outside unit is fast it will take about 20 minutes to clean the coils on the condensing unit. With a chemical it might be a little faster but it usually depends on the air conditioning unit in question. Getting some air conditioning systems clean involves taking them apart. Nothing about disassembly is fun but when certain air conditioning systems get to dirty then they will need to be taken apart to remove enough of the dirt to make a difference in the cooling ability of that air conditioning system.
