Four Potential Dangers Of HVAC Systems Everyone Should Know

Blog

HVAC (heating, ventilation and air conditioning) systems have inherent or potential dangers that everyone should understand. Here are some of those dangers:

Electrical Shock

The risk of an electrical shock is always present with a malfunctioning HVAC system or a poorly maintained HVAC system. This is because a typical HVAC system has multiple electrical components such as capacitors that energize motors to start them moving and keep them running and relays that transmit electrical power. It's easy to get an electrical shock if you don't have the requisite knowledge or skill to handle electrical issues and you are trying a DIY HVAC repair. The best precaution for electrical shock is to maintain the unit and avoid DIY repairs for things you don't understand.

Mold Growth

Mold thrives in moist air, which means your HVAC is likely to experience mold growth if it is constantly moist. Unfortunately, mold in the HVAC is dangerous because it can spread through the house via air circulation, and mold is a known risk for respiratory ailments. You should suspect mold in your HVAC system if there is a strong mildew smell in the house; your eyes, nose, throat are constantly irritated, and you are always coughing and sneezing. Here are a few measures to help prevent mold in HVAC systems:

  • Regular filter replacement
  • Proper duct insulation
  • Regular drip pan cleaning
  • Use of dehumidifier

Fire Outbreaks

The risk of fire outbreaks from your HVAC system partly depends on the source on the type of heating you use. For example, if you have a gas furnace, then fuel related problems such as leaking fuel lines or malfunctioning valves may lead to fire outbreaks. There are also dangers that may trigger fire outbreaks in all systems, even those not running on combustion fuel. For example, an overheated unit may break down and cause fire and an electrical fault may also cause trigger an electrical fire. The best way to prevent HVAC fires is to ensure all maintenance schedules are performed and teething problems are solved before they become major problems.

Refrigerant Leak

There are two chemical leaks that may come from your HVAC system; a refrigerant leak and a gas leak. The refrigerant leak can irritate your skin, shortness of breath, skin dryness, and other respiratory issues. The refrigerant leak may also damage your HVAC system by making it run too hot. Here are a few tips to prevent refrigerant leaks:

  • Don't let your dog pee on the outside unit because the acid in the urine may damage the coils
  • Prevent physical damage to the outside unit, such as those caused by flying rocks during lawn mowing
  • Maintain your system regularly so that emerging issues, such as rust and corrosion, are nipped in the bud

Streamline Your HVAC System

As a DIY enthusiast, I started doing everything I could to make my household appliances more effective then ever before. I insulated my attic, worked on cleaning the vents around my kitchen appliances, and eventually turned my attention to my air conditioner and furnace. Unfortunately, the process of taking care of my HVAC system was more intense than I had originally anticipated. I realized that I needed to read about air conditioners and furnaces before I started tinkering around. I made this blog to showcase all kinds of different articles that talk about HVAC, so that you can become a more informed homeowner.
