An old antique shop down the street was under renovation.
It was about time they used that space since the shop had closed for nearly two years.
I work for a home services company as an HVAC tech, and the realtor for the shop called asking for heating maintenance. I knew the shop would need extensive heating repair because I doubted anyone had bothered to check the heating device when it was closed. I carried all the necessary tools because I knew I had plenty of work ahead of me. I contemplated asking a fellow HVAC serviceman to accompany me, but all were in the field. When I arrived, the furnace was in disarray, just as I had anticipated. It was clear from the digital thermostat that they had switched off the unit, but it must have been running for a while, even after the shop was closed before they switched it off. I have worked in the heating industry for years, but the state of the filter was rare. It had all manners of grime and filth. The heating installation surprisingly did not have a lot of technical problems. An inspection of the ductwork proved that it required cleaning. It also needed duct sealing. I completed the work in time for my next appointment, servicing a heat pump we had installed some years back. The owners took good care of it and subscribed to our emails to get information on the latest trends in heating technology, and as their heating dealer, we always supplied them with the information they needed.
