The clogged HVAC duct almost caused a fire

I was glad we did not need to purchase a new air conditioning system

My sister called me frantically going on about a fire that could have killed them. I had just seen her over my lunch hour and when we parted, she said she was headed home. Now she was calling me while at the hospital. I had just gotten back to the office after executing a quality air conditioner tune-up on a system in a residential house on the far east side of town. I received the call just as I was exiting the lifts at the HVAC business. When I got to the house, my sister was still very upset and could not explain what had happened. There were firemen everywhere as well as cooling experts. One of the cooling specialists explained the entire thing after the firemen had cleared the house. It appears that there was almost a fire that would have burned the whole house down. Upon further investigation, it was established that the cause was from the HVAC duct which had been clogged by dust and dirt. This had limited airflow and decreased indoor air quality. A new contractor in the HVAC team pointed out that our ducts were leaking which would have contributed to the small fire. The technicians did the duct sealing and also checked the temperature control to ensure its optimal function. Since we had two systems, the heat pump and the mini split air conditioner we requested the technicians install a zone control that would not maintain safety but also conserve energy and solve uneven temperature issues. I was glad we did not need to purchase a new air conditioning system. We also got to keep the thermostat as it was still perfectly functioning. The technicians emphasized the importance of regularly cleaning the air filters and vents.
