Chris performed several tests to make sure all potential issues could be addressed. He was able to get the heater up and running so that we could at least have heat until we replace the unit.

Found first floor propane gas furnace with inducer motor running proving pressure switch and send 120 volts to hot surface igniter but igniter was not glowing. Found very rusted and corroded heat exchanger. Furnace is about 15 years old recommended that beacause of condition of gas furnace, to replace system. Also explained to homeowner that it is also beneficial to replace the a/c with the furnace at the same time. Also gave customer a price on replacement of the hot surface igniter. Was not able to perform a combustion test due to system being down. Set up appointment with office for 10:30 am Monday to give an estimate on system replacement.
When I arrived found furnace on a code 14 which board defaults to from a code 34. Cycled on furnace and furnace fired up correctly. Checked venting for furnace at outdoor unit just to make sure there was no debris in piping. Cycled furnace on and off to try to re create issue. After a few cycles did find when cabinet door was on door was pulsating a little bit then flames went out. Could not see very well down intake pipe so pulled off intake pipe for now off of furnace , homeowner is going to run a fish tape and vacuume on intake pipe. This is a good test to rule out any blockage in intake pipe. He will let us know if any other problems persist then to start thinking about replacement of the gas valve.
Found weak 10 mf capacitor testing at 8.2 mf. Replaced capacitor and tested. Performed precision heat tune up on 2 carrier gas furnaces. Checked all electrical conections and components. Replaced 2 16x25x1 air filters. Checked both humidifier pads, both were clean. Blew out condensate drain and pressure switch tubing. Checked temperature rise on both furnaces. Performed combustion test on both systems. Gas furnaces are working fine at time of inspection.
Heat tune up on 2 older s system at this residence. All vital signs good. Integrity of both heat exchangers proven both operating at designed efficiency. Cleaned humidifier housing of basement unit. Notified homeowner that an inspector may be concerned with accessibility to garage unit due to shelving. Both systems are operating well at this time.
Performed heating maintenance on lp boiler. Cleaned burners gun and sensor. Adjusted manifold pressure to 3.39†from 3.97â€. Cleared air intakes. Tested limit and safety switches. Checked draft. Inspected flue pipe. Checked barometric damper. Checked water pressure and temperature.
Replaced blower relay and gave thermostat a call for a/c. Found that as soon as new blower relay picked up it chattered and blew 3 amp fuse. Disconnected g wire at air handler and outside unit came on normally. As soon as I attached g wire to terminal block at air handler relay chattered and blew fuse, found a blew wire going from thermostat to air handler. Switched out blue wire from green wire that was on g terminal, still blowing 3 amp fuse. Checked over low voltage wiring going to blower motor found no knocks. As soon as it was getting 24 volts to t4 motor terminal, it would blow fuse. Removed low voltage speed tap from terminal block and cycled on fan on at thermostat. A/c came on . As soon as I reconnected low voltage wiring to x13 blower motor. Fuse would blow. There is a short in the x 13 blower motor. Motor will need to be ordered and replaced.
Performed Precision Heating Tune Up on Ruud Heat Pump System. Checked Air Filters. Filters were recently changed and in good condition. Inspected Electrical components on Air Handler and on outdoor unit. The Capacitors on the on the Outdoor Unit were testing within rating. The Start Capacitor has some corrosion forming. Recommend replacement of the Starting Capacitor and Starting Relay to prevent any issues with the Compressor. Tested Auxiliary Heat Kit and measured amp draw on elements. Measured Refrigerant charge on system. Verified Refrigerant charge with manufacturer specifications. Measured Air Temperatures on system. Included Estimate for the replacement of the Starting Components. Would recommend having this replaced during the Spring tune up to prevent any issues during the summer.
Heat Pump Tune Up. All electrical components within spec. 37F temperature split on call from heat pump. 7.2 KW strip heater pulling 40. Amps. Changed homeowner provided 413 filter. Opened valve on humidifier and verified humidifier operation. System is operating well at the time of this tune up.
Checked no heat complaint, found furnace locked out on flame failure. Checked ignition circuit and found a failed ignitor. Replaced ignitor, checked air filter ok. Started gas furnace, cycled and checked operation.
Performed precision Heating Tune Up on Rheem Oil Furnace. Air Filter had recently been changed and was in good condition. Replaced Oil Filter, Oil Nozzle, and pump strainer. Found electrodes were very worn. Replaced Electrodes and set positioning. Cleaned Heat Exchanger and flue piping. Visually inspected Heat Exchanger. Inspected chimney base to ensure it was clear. Tested Transformer on Oil Burner. Put system in operation and performed a combustion Analysis, draft test, and smoke test. Measured Air Temperature Rise on system. Set Humidistat control to setting 3 as per homeowner. Oil Furnace is about 31 Years old and the AC system is about 9 Years old. Due to the age of the Oil Furnace, planning for replacement of the Furnace is recommended.
Performed heating maintenance, checked air filters ok. Cleaned burners and flame sensors, inspected heat exchangers. Blew out condensate trap and drains. Checked voltage, amperage and electrical connections, measured capacitor values. Started gas furnaces, tested limit and safety switches. Measured fuel pressures. Performed combustion tests. Checked operation and temperature rise.
Found water pressure coming into home spiking at over 120 psi. Measured water pressure at both where the water comes into the home and at the water heater both were pegging the gauge at over 120 psi. Recommend to homeowner to install a pressure reducing valve on the 1†copper main. While I was there on site homeowner contacted his neighbor and the neighbor said that they have pressure reducing valves installed at the street to feed the homes. Recommend to homeowner to contact the water supply company to have this pressure issue addressed. Let homeowner know that this can damage the water heaters relief valve and other plumbing fixtures inside the home if let un- addressed. Homeowner will contact the water company at this point.
Heat tune up on Lennox 90% single stage furnace. Verified thermostat operation and cycling of furnace. 67F delta. Cleaned flame sensor. Electrical components reading within specs. Unit drawing 2.65 amps during heat cycle. Cleaned drain using C02 drain gun. Replaced 16x25x4 filter. Combustion test proved integrity of heat exchanger and that furnace is operating efficiently. System is operating well at the time of this maintenance/ tune up.
Checked no hot water, found water heater locked out on pressure switch. Found inducer running. Checked pressures, found a restriction in the vent pipe. Checked pipe, found a dead mouse in the vent termination. Cleared vent pipe. Reset lockout. Started water heater and checked operation.
Heat tune up on Arcoaire 2 stage gas furnace. Verified operation of thermostat and cycling of furnace. 50F temp rise. Verified humidifier operation but Removed old humidifier pad and shut off water line and closed humidifier damper (Mrs. Smith will decide if she wants us to replace later.) Gas pressure was reading slightly low 3.12†WC, adjusted to 3.5†WC. Cleaned hosing at secondary heat exchanger. Replaced 16x25x1 filter. All electrical components reading well. 50F temp rise. System is working well at this time.
