When was the last time you checked your AC unit? Have you ever tried cleaning it yourself? Unfortunately, more than 95% of homeowners fail when it comes to doing regular maintenance with their own HVAC. Most people don’t even have the time to check their own AC unit.

If you keep this lousy habit, it’s time for a big change. An uncleaned AC unit, especially its filter, can be hazardous to your health. In addition, this is also one of the reasons you’re dealing with high energy bills.

Still not convinced of getting your HVAC cleaned? Let’s discuss some of the negative effects and possible risks of failing to maintain your AC unit. Below is a list of the negative effects of poorly maintained HVAC:

Health Hazard

If anyone in your home has asthma, you can guarantee that it will worsen with a dirty AC. In the event it turns into severe asthma, regular treatment won’t work on it. That means you’ll have to double the money you spend on medications and find a better treatment for them. Additionally, you really wouldn’t want a member of your family to suffer from this.

Symptoms can often occur throughout the day and wake you up every night. And the symptoms themselves aren’t good either:

  1. Wheezing
  2. Coughing
  3. Difficulty in breathing or shortness of breath
  4. Chest pains and tightness

Besides worsening asthma cases, allergies are also prevalent with a dirty AC. That’s because there’s an increase in dust and dirt in the air. If you inhale it, you might end up sneezing non-stop. You and your family may also experience irritated skin, nasal congestion, and frequent headaches. And all of that can be a result of an unclean AC unit.

Unit Problems

If you don’t clean your AC, expect to replace them in no time. While most AC units can last up to 20 years, this is because users know how to properly maintain them. If you abuse your units combined with zero-maintenance, then you need to change your expectations.

Without cleaning your AC, dust and dirt accumulate on every nook and cranny it can find. It can build up, making your unit work twice as hard to provide you with cold air. It will heat up faster as every part works double time. In the end, it might simply give up on you–or it can also overheat. This is also the reason why your electric bill increases. Your unit is actually eating up twice the energy it needed due to its dirty coils.


If you care about your family’s health and you want to save money, start by cleaning your AC. You’ll need a professional to have it thoroughly cleaned at least twice a year. But, you must also regularly clean the AC filter at least once a week if you’re regularly using it.
