Most air conditioning problems are never as serious as problems associated with other HVAC systems, such as gas leaks from your furnace. This, however, does not mean that you can or should ignore the maintenance and repair of the AC unit.
The majority of air conditioning issues result from dirty filters and other general neglect. By quickly addressing any issues that you encounter, you will save money and feel more comfortable in your home. Here are common problems that arise from overlooking maintenance. 
Suboptimal Cooling Abilities
There are several minor air conditioning issues that will make your air conditioner less effective at cooling your home. If a dirty filter is installed, the dust built-up will block airflow, resulting in reduced energy efficiency. Your air conditioner will be working harder, while supplying warmer air. Filters can be easily cleaned or replaced, depending on the type of AC you own, and fixing this problem can increase efficiency by up to 15 percent.
Another common issue that causes lower cooling abilities is a slow fan. If a fan is running at half the normal speed, you will definitely feel the heat during the summer. When you notice that your air conditioner is not as effective as it used to be, you should call your technician to inspect the problem and make repairs before it gets too hot.
Higher Energy Costs
If you have noticed that your air conditioner makes strange sounds or emits odd smells while operating, it is most likely dealing with an internal issue that is draining its energy and your money. Even if you have not experienced a drop in your air conditioner’s cooling quality, there could be an underlying problem that is causing stress to the system.
This stress forces your air conditioner to compensate and exhausts its power. Make sure to address any mysterious sounds or smells to lower your future expenses. If you decide to ignore the problem, you will pay for it later with your electricity bill.
Expensive Breakdown Repairs and Replacements
When you continuously allow your air conditioner to run without taking care of minor issues, you run the risk of experiencing a full breakdown. Constant stress on a broken part within the air conditioner will lead to more broken parts and more malfunctions. As it further degrades, the costs of repairs begin to rise. Your simple $60 repair can easily turn into an $280 dollar expense, and that’s just the beginning.
Eventually, your air conditioner will be unable to handle the demands of the scorching hot day in Los Angeles or anywhere in the San Fernando Valley, leading to complete failure. At this point, you may be forced to buy a completely new air conditioner, which far exceeds the costs of minor maintenance repairs.
As a SoCal resident, you know how hot it can get during the day. Ensure that your air conditioner is fully able to keep you cool in the summer by fixing small issues as they arise instead of allowing them to build up. Consider the risks to your comfort and wallet the next time your air conditioner begins working improperly.
