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.

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.

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.
