When the hydronic heating device started making unusual noises, I called the HVAC business and booked an appointment with the HVAC repairman.
I had several ideas about what was wrong with the system but decided to let the HVAC techs do what they do best. I had had recurrent flu infections that had started worrying me. The flu infections began after returning from my spring trip abroad. The quality heating device had become so inefficient that my bedroom felt cold since winter started. My nights got very uncomfortable that I had to invest in a portable space heater to enhance whole home heating. The furnace/heater installation was done five years ago, so I knew I was not dealing with an old system. Since installation, I had only had the heating contractor come once to do the furnace/heater repairs. The HVAC providers did the furnace/heater tune-up and discovered a mold that had been growing in the attic. From the assessment, the professionals found that the mold started growing during summer. It had grown into the system, causing a blockage and restraining airflow. They cleaned all the mold from the walls and the system and restored the optimal condition of the quality HVAC equipment. The mold had also messed up the temperature control device, so we got a new and better one from the supplier. The professionals helped improve indoor comfort. Since the mold was cleaned, I have noticed that the flu infections have reduced drastically. In fact, I have not had the flu in three months. The engineers advised that I get a worker to check for any regrowth over the next few months.
