4 Ways Your AC Can Get You Sick & How To Solve It

If you or someone in your family are experiencing flu-like symptoms, and after treatment with medication, fluids, and rest still see no changes, it could be something caused by your AC.

In this situation, sometimes you feel a little better being outdoors. This scenario isn’t uncommon among homeowners.

Some of the possible symptoms of poor indoor air quality include:

  • Breathing Problems (asthma attacks)
  • Fatigue (headaches or dizziness)
  • Flu Like Symptoms (coughing, sneezing, runny nose)
  • Allergy Symptoms
  • Watery or Itchy Eyes
  • Scratchy, Sore, or Dry Throat
  • Skin Discomfort (itchiness or dryness)
  • Bloody Nose or Sore Nasal Passages

If you experience these symptoms and can’t seem to get better, it might not be a cold or flu you’re battling, but an AC problem.

We have seen how people can get sick from poor indoor air quality, and if you’re sick you should absolutely see your doctor for proper diagnose & treatment. Fortunately, if you are suffering from prolonged symptoms caused by your AC, here are 4 solutions that can make a difference.

1. Fungi/Mold

Possible Symptoms: Irritated skin, watery eyes, coughing, sneezing, asthma attacks, and lung damage. Potential for bronchitis and pneumonia.

Problem: Starting out as small fungi, mold lurks in the moisture rich environments of your home. It rapidly advances in cool, damp areas and evolves into circular patches.

Once it grows it becomes visible spores threatening your health and comfort even flying under your radar into the air you breathe. In the noticeable stages, it can be stains on your wall or a foul odor.

Hazardous to your house and health, it is visible in water damaged areas, ceilings, walls, filters, insulation, coils and ducts (locations of great moisture build up). As cool air goes through the coils and air ducts, the condensation causes moisture development, feeding the fungus.

Worse still is black mold, which is even more dangerous because now it has become airborne. At this level, it causes respiratory problems and possible lung damage.

Solution: Through cleaning, quality ventilation, and sunlight exposure you can terminate low to moderate mold.

If, however; it’s covertly hidden, it’s likely lurking in your central AC. This is where the professionals come in. It also helps to have your AC serviced at least once a year for maintenance upkeep.

Regular cleaning is still essential.

A well-maintained filter acts as your shield of defense from pollutants and viruses and when it’s left collecting all that filth and debris, it starts getting released into the air you breathe. That is why your filter needs changing every 1-3 months especially if you have pets.

2. Circulating Contaminants

Possible Symptoms: Difficulty breathing. Potentially cancerous risks.

Problem: Overtime indoor air starts accumulating contaminated pollutants. These air polluters may be mold, dirt, dust, household cleaners, air fresheners, perfumes, nail polish removers, pet dander, etc.

As old air is circulating these chemicals, you and your family are at risk of catching air-borne infections and viruses from breathing in dry, stale air and exhaling moist air. Humidity starts to grow in the room and creates a germ infestation.

This is when you absorb those flu and allergy symptoms and you become contagious.

Solution: If your home doesn’t have a place for the “extra air” when the AC is used, you can create a type of air “leak” by opening windows and having fresh air come in.

Another alternative is a dehumidifier.

Since dehumidifiers lower the humidity, your home becomes an extremely difficult place to host mildew. The dust quantity is reduced. A plus is your energy expenses lower because dehumidifiers help ACs run smoother.

You can enjoy the benefits of maximized comfort and more breathable air. Your food stays fresher, your clothes are safer from mold and mildew, and your tools and electronics are prevented from rusting.

3. Insulation with Air Leaks

Possible Symptoms: After some time, there may be long term affects if not cared for such as respiratory problems or the potential for lung diseases.

Problem: Insulation leaks are expensive, uncomfortable and annoying.

It’s quite frustrating trying to relax, but coming across an unending draft. With outside air flowing in, the moisture starts to pick up then you must face mold growth. With outdoor contaminants flowing in you’re now facing possibly getting sick which is preventable.

Solution: Having your insulation checked once every year assists with the prevention of entering pests, contaminants, and pollutants.

Plus, any cracks or holes that get sealed in the openings of your home, typically the attic or basement, will result in better air quality and is a cost-effective decision.

4. Poor Ventilation

Possible Symptoms: Skin and throat irritation, hypersensitivity, fatigue, sinus congestion, irritated nasal passages, bleeding nose, shortness of breath, nausea, and allergies.

Problem: In the case of poor ventilation here are some things you may be experiencing.

The registers aren’t releasing sufficient air. As soon as you place your hands near the registers there is hardly any cool air.

Warm air is blowing instead. Your house is starting to heat up rather than cool down.

There is a hot and cold temperature variance. There are temperature inconsistencies and you feel mostly heat.

Solution: Sometimes the best option is to get a new AC. Poor ventilation can be a system failure or an old, damaged compressor which is the heart of the system.

Simpler decisions you can make on the other hand, can be opening windows for fresher air, using exhaust fans from bathroom and kitchen, making sure there is no furniture restricting air flow, making sure your AC is the right size for your home, or even using mechanical ventilators which properly heat and cool fresh air and aid in greater fan efficiency.


If you have been suffering from all kinds of symptoms and not getting any better the culprit could be your very AC.

ACs need to be well maintained and thoroughly cleaned. There are consequences with your expenses, home, comfort, and health and for now they may appear short term. If you neglect the possible signs and don’t care for the simpler problems your costs can skyrocket, your house will be a toxic environment, and worst of all you may not feel better.

The good news is if you are facing these problems Vital AC can assist you and improve the air quality in your home and you can feel much better.
