• Here are some examples of when you need to call your air conditioning company or air conditioning contractor to send in a technician:
Your ductwork is making too much noise. The technician can provide proper flexible insulation to fix the problem

Ice is blocking the tube and no cold air is coming from the air conditioning filter and the filters have recently been cleaned. This means your air conditioning refrigerant is low and needs to be re-adjusted or replaced.

The air handler sounds like its making grinding noises. The air conditioning parts could be loose and might be hitting each other. This is when you need to have the technician come in to do air conditioning repair or install new air conditioning parts .

• You have not cleaned the ductwork in years or just purchased a home and noticed the ductwork looked like it had "snow" on it - a term for caked dust on top of all the air ducts. This is the time to have the air conditioning company come in and clean it all and make sure it's not going to cause a problem with your central air conditioning, if it hasn't already. Make sure they also check all the air conditioning parts to see if anything has rusted or has been slow to operate due to the buildup of dust.

• Often times, there are old homes that are purchased to fix up and renovate. Since their air conditioning systems might be ancient, have an air conditioning company check out the units and give you an estimate of the damage. It can become costly to replace parts rather than investing in an entirely new air conditioning system. Consider your options before signing on the dotted line.
