The unit still actively and quickly cools the house, but it was burning something causing Carbon monoxide and nauseousness.

This was confirmed by the emergency utility technician that came out to rule out a gas leak and help identify the problem.

Could opening more registers or removing the register filters help solve this issue? The builders used the floor registers as a trash can for sweeping away debris, so I had put filters to try to keep the air cleaner for my family.

We also closed some registers (as directed on the main unit's instructions) to help push the cool air to the top floor (upstairs is always hot, anyway, and the first floor is cold).

Could this be incorrect? .

I try to educate myself and find resolutions to be responsible and keep everything in best condition, but I am not a technician.

Has anyone seen this before? .

I would like to try removing the filters and opening registers to see if it still overheats, but I also don't want to become a Google News article of a family that died of carbon monoxide poisoning or exploded after a fire in my HVAC system.

Answer:

I can try to provide some general guidance based on the information you've provided. It's important to note that HVAC systems can be complex, and it's always best to consult with a qualified technician who can assess your specific situation. However, here are a few points to consider:

1. Carbon monoxide (CO) and nauseousness: If your HVAC system is producing carbon monoxide and causing health issues, it's crucial to address the problem immediately for the safety of you and your family. Carbon monoxide is a poisonous gas, and its presence can indicate a serious issue with your heating system. It's good that you had an emergency utility technician visit to assess the situation.

2. Register filters: Using filters in your registers can help trap dust and debris, preventing them from circulating in your home. However, if the filters are restricting airflow too much, it could lead to overheating of the HVAC system. You can try removing the filters temporarily to see if it improves the situation, but again, it's best to consult with a professional technician who can advise you on the proper use of filters and ensure they are not causing any issues.

3. Closing registers: Closing registers to redirect airflow can affect the overall balance of your HVAC system. It may cause pressure imbalances and potentially impact the efficiency and performance of the system. This imbalance can also lead to overheating. It's advisable to follow the manufacturer's instructions or consult an HVAC technician to determine the best way to optimize airflow in your home without causing any issues.

4. Safety concerns: Your concerns about safety are valid. Carbon monoxide poisoning and the risk of fire or explosion are serious hazards. It's essential to prioritize the safety of your family and avoid taking risks with your HVAC system. Consult a professional technician to investigate and resolve any issues, as they have the expertise to diagnose problems and provide appropriate solutions.

Remember, it's always better to rely on professional advice when it comes to HVAC systems, as they involve potentially dangerous gases and electricity. A qualified technician can assess your specific situation, identify the root cause of the problem, and provide the necessary repairs or adjustments to ensure your system operates safely and efficiently.
