Your air conditioner turns on, but it doesn’t blow cold air. This is a sure sign that something is wrong with your air conditioning system. But not blowing cold air is not the only thing that can go wrong with your ac unit. Depending on the age of your system, it may or may not be prone to problems. But it’s possible that any air conditioner, regardless of its age, will need repair service at least one time per year. When it comes to air conditioner repair, it’s best to catch and fix the problem early. If a problem is left unfixed, it can potentially lead to more serious and more expensive issues. Therefore, if you sense that something is wrong with your unit, make sure to schedule an appointment with an air conditioner repair company as soon as possible.

Following are signs that it’s time to call for air conditioner repairs:

Your air conditioner turns on, but it blows hot air. As stated at the beginning of this article, a central air conditioner that blows warm air instead of cold air is obviously not functioning correctly. This is relatively common problem and oftentimes requires a simple repair. It’s always best to have an air conditioner repair service company visit your home to evaluate your system and provide you with a proper diagnosis.

Your air conditioner turns on, but the air flow coming through your air registers is very weak. Lower than normal air flow from your HVAC system is another relatively common problem. It may be that your system’s air filter is very dirty and simply needs to be replaced. Or, the problem might be more a bit more complex and involve the system’s blower. Ignoring a problem with air flow will not cause it to resolve on its own. You can always try replacing your air filter to see if that will solve the problem. If it doesn’t, it may be time to call an air conditioner repair company.

Your air conditioner smells bad either when it’s running, when it’s idle, or both. No matter what, your air conditioning system should not smell bad. Odd smells that come from an air conditioning system should be evaluated by a professional air conditioner repair company. A bad smell could signify that the system is overheating or that it is harboring mold (or something else!).

Your air conditioner makes unusually loud or strange noises. Central air conditioners do make a certain amount of noise when they run. But the noises emitted from your air conditioning system should not be loud enough to cause an annoyance to you, your house guests, or your neighbors. If your system suddenly starts making odd noises, or your system makes noises that seem out of the ordinary, make sure to call an air conditioner repair company for an evaluation. The system might require a simple fix, or it might need more in-depth repairs. Either way, it should function more efficiently if it is in good working order.
