Customer stated there is no domestic hot water from boiler, found system off upon arrival, boiler is firing, check hot water side and noticed no mixing valve is present, found a manual valve was slightly open mixing with the hot water this was costing lower temp on the outlet, closed valve would recommended adding a mixing valve to regulate water temp to prevent any asking damage, also during inspection could not check boiler pressure, both valves can’t be open, massive corrosion is around valves and can’t not be open, explained to customer water pressure on boiler can’t be checked, also expansion tank is full of water and can’t be drained, due to malfunctioning of drain valve, boiler is in bad shape needs cleaning, emailed proposal, for recommendations would recommend replacing boiler

Service call the Gas Furnace was not working, and we were onsite the previous day for a Maintenance. Upon arrival found unit locked out on a 3 Flash/Pressure Switch Code. Cycled power and measured Pressure across the Pressure Switch. Found unit was not running at a highest pressure and the Inducer Motor was filling with water. Found Drain Line was clogged after the Main Furnace Trap. Cleared Drain Line and found a rubber cap was lodged into the drain. Removed and reassembled drain line. Put system in operation to test.

Service call that the Oil Furnace was not working. Upon arrival found system turned off. Homeowner informed me that he recently replaced the Oil Filter and Oil Pump and coupling. Put system in operation to test. Furnace was coming on and attempting to light, but would shut down after not igniting. Inspected components and found Oil Nozzle completely clogged and Electrodes very worn. Replaced Electrodes and set positioning. Installed new Oil Nozzle and cleaned assembly. Put system in operation to test. Performed Combustion Test, Draft Test, and Smoke test. Replaced 16x24x1 Air Filter provided by the homeowner. Temperature rise of Heater is very high. Measured a 110 Degree temperature rise. Supply duct work is undersized which would cause the higher splits. Cycled system to ensure it was firing properly. Would recommend a full maintenance being performed on the system. Furnace is about 25 Years old. Due to age, would recommend replacement of the Furnace.

Service call that the Heat was not working. Upon arrival found home at 61 Degrees with system turned off. Turned heat on to 70 to test. Gas Furnace was not coming on and Indicator Light on Control Board was blank. Checked Voltages and found 120Volts incoming. Found Door Switch was broken which was keeping the system off. Bypassed door switch and put system in operation. Checked 16x25x1 Air Filter. Performed a combustion test and measured Air Temperatures. System has not had any maintenance performed since 2018. Would recommend replacing the Door Switch as this is a safety feature. If the blower door is opened the system will continue to run without the door switch. If opening door to change filter need to shut power off to furnace at the switch on the unit. Included an estimate for a new Door Switch and performing a Heating Tune Up on system.
