When the heat pump started making uncorrect noises, I simply called the heating supplier and booked an appointment with the HVAC repairman.
I had several ideas about what was wrong with the system but decided to let the heating dealership do what they do best.
I had these recurrent flu infections that had started worrying me. The flu infections began after returning from my Spring trip abroad. The heating system had become so inefficient that my bedroom felt cold since winter time started. My afternoons got so uncomfortable that I had to invest in a portable space heating system to enhance apartment heating. The heater/heater upgrade was done five years ago, so I knew I was dealing with something other than a seasoned system. Since upgrading, I have only had the heating company come once for a boiler repair. The company did the heating system service and discovered mold 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 hybrid heating system. The mold had also messed up the temperature control device, so we got an up-to-date and better one from the dealer. The professionals helped improve indoor comfort. Since the mold was cleaned, I have noticed that the flu infections have reduced drastically. I have not had the flu in three months. The engineers advocated for me to get a worker to check for any regrowth over the next few months. The hydronic heating system is better than ever. With biannual HVAC service, the heat and AC product is doing well.
