I was dispatched to a home service company to repair a faulty heat exchanger. The unit had been shut down until the replacement part could be installed. I arrived at the site and began the process of removing the old heat exchanger. It was a complex procedure that required careful attention to detail. Once the old unit was removed, I installed the new heat exchanger and connected all the necessary pipes and wiring. I tested the unit to ensure it was working properly and then made sure that everything was clean and tidy before leaving the site.
