- Carbon Monoxide (CO) – This is probably one of the biggest risks associated with a faulty HVAC system. If your system uses natural gas or propane, you have a higher risk of being exposed to carbon monoxide if your system has a problem. A leaking heat exchanger or bad chimney could cause CO to leak into your house. Since it is an odorless, colorless gas, it can make you sick or even kill without you ever realizing there’s a problem.
- Mold – If your system is not functioning properly, it could increase your risk of being exposed to mold. An HVAC system that is retaining moisture can create the perfect environment for mold to grow. Additionally, if it is not properly cooling your home, you could have a higher risk of mold in your home, especially during the summer months.
- Dust and other allergens – Another possible risk from a malfunctioning heating and cooling system is an increase in dust and allergens. All HVAC systems have filters in them that remove contaminants from the air. Filters come in different qualities and can filter almost anything out of the air in your home. However, if your system is not functioning correctly, it may allow dust and other allergens to bypass the filter. It may also not move enough air to effectively filter contaminants out of the air.
All of these potential health hazards are a great reason to have your system regularly inspected by a professional to make sure that everything is
working perfectly. Additionally, it is also important to make sure that you are regularly cleaning or replacing the filter in your system. Most professionals recommend that the filter is replaced once a month to ensure that your system has the proper amount of air flow and to make sure it is effectively cleaning the air in your home. It is also a good idea to have a carbon monoxide detector installed in your home as well. If your system is releasing CO into your home, a detector will alert you and allow you to get your family to safety quickly.
So, what are some signs that your system is in need of repair? Take time to listen to your HVAC system; it should have a familiar hum to it. If that hum ever changes, it could be a sign that something is not working appropriately. Also, a properly sealed and functioning HVAC system should not be emitting any strong odors. If you are near your main system and notice a smell coming from it, or if you notice unusual odors coming from the vents, that could be a sign that something is amiss. With the seasons finally changing, now is a great time to have your system inspected and any heating repairs taken care of before the heat of summer returns to Minneapolis.
