During our visit, the customer mentioned they had a water heater that was leaking and wanted a quote to replace. Upon inspection, I noticed they had two water heaters. They were installed in a series and the left unit was leaking. I spoke with the customer about a few different solutions. Multiple estimates were provided and presented. An estimate was approved for replacing both water heaters. The 13 year old tanks were replacing with two new 50 gallon gas water heaters. Each water heater received an anode warranty extension kit. This increased the manufacturer warranty to a total of 10 years. A new grundfos Alpha recirculating pump was also installed. The customer downloads the Grundfos go app and I helped him setup the pump. The customer is aware that the water heater venting is not up to code. One of our hvac techs provided a quote to correct the venting. The customer is responsible for making the decision on proceeding with their quote or not. While installing the water heaters,

Arrived ed for no heat in lobby area. Inspected Carrier furnace electrical, gas components, filters and heat exchanger. Furnace was flashing fault code for high limit switch. Carrier furnace labeled #1 had a filter stuck in blower motor. Filter was very dirty and nothing to hold it in place which led to being pulled into blower motor. Also found a failed heat exchanger as seen in images from surrounding insulation burning to a cracked ring. Beginning section of single wall 4" flue pipe is installed upside down leaving air gaps around crimping for co to leak out. All flue vents for either furnace and water heater are single wall pipe and show rust through out flue. CO detector is picking co levels in utility closet possibly from flue condition/installation and failed heat exchanger or both. While in utility closet faint smell of natural gas was noticeable. Found gas line goin into water heater was leaking and recommended immediate repair. Inspected furnace #2 that showed no issues while

Arrived on site to perform troubleshoot for office circuit tripping breaker. The homeowner informed us that he had his home pressure washed recently. We inspected an outdoor outlet on this circuit and notice it had water. This outlet was not weather rated and was not sealed properly. We installed a new weather rated outdoor outlet with a new bubble cover. We sealed around the cover to ensure water cannot enter. We also went through and put a heat gun on both the office and den circuits. We tested all lights as well. The circuits are now operating as they should.
