Sometimes, your central air conditioning is just not up to par and you can see there might be a problem with your heating and air conditioning . For example, you might not be getting adequate cool air blowing from the air vents. Well, have you cleaned your air filters? If you haven't, that could very well be the solution and you might not need to have your air conditioning unit repaired. Looking through your manual and locating where you think the problem lies will give the HVACR technician a general idea and an opportunity to solve it faster. If you have cleaned the ductwork, raked all the leaves around your outside unit and changed the air conditioning filters, and there is still a problem with your air conditioning, it might be time to call an expert. HVACR technicians specializing in maintenance and repair can give you advice over the phone to see if they should come in or if it's something you can solve. If it's near your annual inspection time, it might be wise to schedule an appointment to ensure there are no leaks or old air conditioning parts needing replacement.

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.

Properly and routinely cleaning the evaporator and condenser coils, air conditioning filters and air ducts can all contribute to the stability and continued performance of your central air conditioning system.
