17FEB2025 Jason Brown Arrived for silver/ blue club tune up service, spoke with homeowner about the systems performance. They explained everything is working well, however there is a noise on the upstairs system. Started with upstairs system. Found filters clean batteries good and thermostat working properly. Cleaned flame sensor and checked through all limits and safeties before cycling heat. Inspected heat exchanger and evaporator coils. Checked heat rise and gas pressure before taking amp draws on motors. Found both systems, while old, operating normally. While checking registers I noticed fill sand at the front dining registers. Discussed findings with homeowner, we decided to get a quote for a video inspection and air scrubber. Attached are discussed estimates thanks and it was good to see you! Fill sand
