I performed a single heating maintenance on a 2022 gas system. I checked amps, filter, electrical, cleanliness, and safeties. I spoke with the customer about the importance of safeties. The customer informed me of power blimps that the home has. I advise surge protection be installed on the unit to minimize damage when these power blimps occur. I observed that the drains do not have the best water protection. I provided an option to install a primary water safety switch and blow out valve. These items will reduce the risk of surprise damages and repair cost. Customer asked that I email the options to the two of them fan review later.
