One of the basic things the air conditioner does is collect dust and dirt from the air to keep it clean, and then provides fresh air back into the air. If the air conditioning unit is not serviced regularly, the dirt and dust will begin to build up and get deposited in the filters. Over time, this dirt and dust will begin to affect how well your AC is working because it makes the AC unit have to work even harder. You will find that you need to decrease the temperature of your air conditioner to get an equal amount of cooling that you were experiencing previously. This leads to your air conditioner consuming more energy, which will jack up your energy bills. Not only is the dirt and dust that has collected bad for your AC unit, it can also be bad for your health when it is released right back into the air. Those suffering from allergic diseases like Eczema or asthma will really feel the negative effects of an unserviced air conditioning unit. Even those who aren’t easily affected by dust could begin to notice some unwanted side effects as it collects in your home’s air.

Air conditioning units also have a lot of parts that need to keep moving efficiently to keep your home cool. Some of these parts are a fan or coils that need proper lubrication and cleaning in a timely manner to keep functioning as they should. Not only is this going to slowly deteriorate your AC, but it will also raise your energy bills as your AC will have to work to provide you with the cool temperature you desire. You don’t want to hear that you have to replace an expensive part just because it got worn down over time, and all you would have had to do to prevent it was add more lubricant.

Many people change their air filters themselves, however, you might find that you’re not getting the proper result with doing the work yourself. This is because sometimes there is a problem you are completely unaware of. You may think that you’re helping the efficiency of your air conditioning unit, but really it’s lack of refrigerant that’s causing the problem, and you need an HVAC contractor to discover it and properly fix it. Often times the low levels of refrigerant are due to a leak in the coolant system. An air conditioning maintenance service will be able to notice this problem and fix it before it becomes an annoyance to you. If the leak is allowed to continue, you could potentially have to face a very expensive problem. Having to replace parts of your air conditioning unit can be very costly, so it’s best to ensure that you’re taking care of the parts you already have on a regular basis.
