Introduction: HVAC System

An HVAC, or what we know as a heating, ventilation, and air conditioning system, is a complex variety of multiple vents that manages the in-let and out-let of air in your rooms. So be it hot air or cold air, the HVAC system ensures adequate ventilation with filtration. It provides thermal comfort. Generally, air vents are attached with either a furnace for hot air or air conditioners for cool air, respectively. You’d find centralized HVAC systems in most homes today because homeowners prefer proper ventilation in their space so that they can live carefreely.

Since the HVAC system is a crucial element of your house, air conditioning service and HVAC maintenance regimens are a must-to-do thing! With routine maintenance of an HVAC system, you can assure yourself of a long-lasting and durable machine that equally distributes the air in your place and functions optimally.

A professional air conditioning repair service prolongs the functionality of the HVAC system, helps it provide hot and cool air efficiently, and reduces power consumption expenses.  When people don’t invest in professional HVAC services, they compromise on quality. There are numerous dangers of poor ventilation caused by poor HVAC facilities. Without maintenance, your HVAC system won’t give you the results you’re looking for. A few warning signs highlight that you likely need a repair. These are high humidity, water leaks, bad odors, etc.

5 Toxic HVAC Smells Indicate Horrible Underlying Problems

1. Rotten eggs or sulfur smell: Usually indicates a gas leak

 An HVAC system has a closed compartment with air filters and water ducts. Such a compact space can produce a foul, unbearable smell if something has gone wrong. The smell that homeowners usually complain of is the smell of spoilt eggs. It coincides with a smell similar to hazardous chemicals that one must report before it’s too late. Since chemical gasses are dangerous for the skin and respiratory organs, homeowners must raise a request to check for a gas leak with their HVAC repair contractors. The earlier you call a professional to look into this concern, the lower your repair cost.

2.  Burning or Gunpowder smell: Burn smell is usually caused by an electrical part or component that has  shorted out

Such smell generally comes when there has been an electrical fault in the AC equipment. The overall system usually works but not efficiently. In addition, it makes the atmosphere uncomfortable, especially for those who have asthma or other respiratory illnesses. To fix this, you can call for an air conditioning repair service. A professional will visit your house to dig deeper into the root cause and amend the faulty component. In a worst-case scenario, an electrical failure related to a dirty air filter, blower motor or coil could further disrupt the HVAC system and make it impossible to use.

3. Exhaust fumes or traffic-like odor: If using a gas-fired furnace, the exhaust pipe may have gotten knocked loose or off the furnace

Be it a power-backed or fuel-backed HVAC system; each contains a combination of harmful gasses that are not good for effective respiration. If you see gas fumes originating from your HVAC system, be it due to a faulty component, it is suggested that you immediately call a professional to inspect each duct and department. In a gas-fired furnace HVAC system, the exhaust fumes can seemingly create quite a few issues in a fraction of time. Therefore, it is important that you take it seriously and not ignore the odor.

4. Musty, moldy, dew like the smell: Usually happens at the first of Spring and the beginning of the Fall. This is commonly known as “Dirty Sock Syndrome.”

Having talked about the HVAC ducts, we now know how these duct compartments stay intact all the time. And since these ducts support the inflow and outflow of cold and hot air, the surfaces may get covered with thick condensation, resulting in mild dew and unwanted mold. So if your HVAC system gives out an odd moldy smell, it could mean that it requires cleaning or the system. An air conditioning repair service can resolve this problem as the professional would clean the system so it doesn’t harm your living space.

5. Chemical aroma: Any chemical smell would most likely be due to a refrigerant leak in the indoor cooling coil

Last, one of the foul smells you may experience is the smell that comes from the refrigerant in the system. On some occasions refrigerant leaks will occur and due to dissimilar metals and corrosion the leak will occur in the evaporator coil. The evaporator coil is what removes the heat from the home and air goes through the coil before entering the duct system then the living space. If the evaporator coil has a refrigerant leak there is a possibility that refrigerant can be put into the living space.
