Most of our time is spent indoors – whether we are at home, at school, or at work. For this reason, breathing in good indoor air quality is vital for our good health. Unfortunately, according to research, indoor air can be more polluted than outdoor air. Germs, bacteria, and dust can hide in many places indoors, especially rooms that are not accessible by natural sunlight.

Many people can get sick and experience certain discomfort due to contaminants found inside a home, office, or building. In fact, there’s a term for this and it is called the Sick Building Syndrome. This term is used to describe certain situations where people occupying a building show symptoms of an illness due to bad indoor air quality.

With many of our homes nowadays with HVAC systems in place, there are instances where pollutants can get inside and make us sick especially when there is no proper care and maintenance for it.

Here are some symptoms you may experience if you have a faulty HVAC system.

  • Skin Irritation

Most of our homes and offices nowadays are air-conditioned to give us maximum comfort during warm days. Unfortunately, the more you spend in an airconditioned environment, the more you must bear the consequences of recycled air. Due to lack of ventilation, your skin can get extremely dry. And when you have dry skin, it can get red and itchy. Therefore, a humidifier is also in place to balance out the environment inside. However, if your HVAC system is not well-maintained, it can worsen symptoms for those who already have existing skin concerns like eczema, rosacea, and psoriasis.

  • Runny nose

Some HVAC units do not have a humidifier which is why indoor air can get dry and cold. Due to the unnatural cold conditions inside, it can result in flu-like symptoms such as a runny nose. When installing an HVAC unit in your home or office, find an HVAC service OKC who can put in place an effective humidifier.

  • Itchy eyes

Having watery and itchy eyes is also one of the symptoms of a faulty HVAC system. If there are holes in your home’s ductwork, it can let in unfiltered air throughout the house and worsen any allergies, including itchy eyes. It is important to schedule an HVAC repair so experts can inspect any leaks in your ductwork, fix them, and improve your indoor air quality in the process.

  • Breathing issues

Dirty HVAC units can be a perfect breeding ground for nasty fungi and bacteria. If there is moisture build-up, it can form black molds which will ultimately bring forth microorganisms in the air that can cause diseases such as pneumonia, high fever, and more. You will start to notice breathing problems, coughing, chills, and a lot more. Luckily, this can all be prevented by regular cleaning and maintenance check-ups.

  • Headaches

Another symptom one can experience inside a house or office building with bad air quality are intense headaches and fatigue. This is most common in office buildings with a central air conditioner.

With all these symptoms in mind, it is equally important to be mindful of what is going inside your home or office buildings. Before you start experiencing any of the symptoms, be vigilant in inspecting any possible issues revolving around your HVAC units or with your HVAC system for a while. This way, you can avoid getting sick and improve your quality of life.


Here are some of the possible HVAC problems you need to be aware of.

Refrigerant Leaks

A refrigerant is a substance that makes your air conditioner or your cooling system work. But if there’s a leak on it, it can result in a lot of health problems and some can even be deadly. Some of the symptoms one can experience when exposed to a refrigerant are nausea, headaches, dizziness, breathing problems, organ failure, and even death.

A few of the common signs you should know if your refrigerant is leaked is if you start to notice ice on the refrigerant lines or hear bubbling noises. When this happens, contact a licensed HVAC professional as soon as possible to fix it.

Contaminated HVAC units

If your HVAC system lacks proper care and maintenance, it could provide a perfect breeding ground for microbial contaminants like mildew and fungi inside your home. As these harmful elements make way to your HVAC components, you will soon be breathing contaminated air. It’s important to regularly schedule an HVAC service OKC to thoroughly clean your HVAC units whenever necessary.

Moisture problems

Maintaining ideal indoor humidity levels is extremely important to prevent any moisture problems with your HVAC units. If your HVAC system is also poorly maintained, it can seriously affect the humidity levels inside your home or office. When this happens, viruses, germs, and dust mites will soon find a way to survive in every nook and cranny indoors. This can result in skin irritation and some cold-like symptoms. On the other hand, if there is low humidity, it can also leave you more susceptible to viral infections. Maintaining the humidity levels inside can easily prevent all this from happening.

Polluted recycled air

To make the HVAC system working well, you must keep your home or office sealed up. The problem with that is that you are also sealing moldy air inside. When this builds up over time, it can reach unsafe levels and eventually make everyone inside sick. Recycled stale air can cause many allergies and contribute to some respiratory illnesses. Luckily, this can be easily be prevented if you:

  • Clean or replace your air filters every month or whenever necessary.
  • Open windows to let fresh air in as much as possible.
  • Install an air purifier or a ventilator inside.


It is important to arm yourself with the knowledge of possible issues with your HVAC system to immediately recognize the cause and act on it accordingly. If you start to notice your HVAC system is already making you sick, it is high time to schedule an HVAC repair OKC to improve your indoor air quality and make your indoor activities a pleasant experience.
