The unit was locked out because during the night it tried to run gas heating and the low pressure switch will not close. I switched it to heat pump only and also lowered the outdoor temperature to 0 to keep it from trying to bring on the gas furnace. I completed a parts order form and a customer follow up form as well. Customer has heat from geo unit and should be fine until the parts are replaced but it still needs to be addressed as quickly as possible. I put a note in the file for whoever returns to replace the pressure switches to increase heat pump lockout temperature to 15 degrees and switch thermostat back to system in control. Might need to lower upstairs lockout temperature to 15 degrees as well.

In the daylight there was only one leak and is was in the upper braze joint where the water pipe joins the coaxial loop. I was able to drain the water from the loop and clean the joint and braze it again going over the entire joint. I let the water back through and checked thoroughly for any water leaks and am happy to say that there are none. I packaged the unit back together the way I had found it. Once power was restored the unit began to operate fromthe thermostat. Unit operating normal.

Upon arrival found 3 top sink faucet to be running and not shutting off. It’s also not diverting properly either. Recommend replacing faucet. Also was advised about the lever drains not functioning. Found them to be free spinning and doesn’t actually stop up the drains and one is stuck in the shut position. Recommend replacing all three of them.

Case # 461345. I called Mitsubishi Technical Support because the compressor makes a very loud aberrant noise and then stops operating. The control board flashed 2 blinks for over voltage. Tech support recommended to replace both the compressor and control board for this unit. The compressor is still under parts warranty but the board is not. Customer not happy with the unit and multiple service calls for this unit and wants to get an estimate to just replace it. I spoke with service manager because no one was currently in the office to schedule. I will have the office follow up with the customer tomorrow to schedule. The estimate is on file as well as a parts order form (estimate,) in the event the customer decides to replace the compressor and control board.

Gas furnace in the basement of the Allnut House has a defective 2 speed inducer motor. The motor itself and the attached fan blade housing assembly need to be replaced. Since the low fire pressure switch does not close the furnace shuts down so I cannot check further operation but the blower is operating and the ignition module is good so replacing the inducer should get the system operational again. I completed a quote sheet and filled in a parts estimate form and submitted them to the office to finalize and search for the parts availability. Customer would like to have it fixed today if possible. I let the head CSR know of this request as well.

The air filter was recently replaced by the customer. Loop pressures are sufficient. I checked the electrical wiring and electrical systems including the auxiliary heat strips, all are within specification, except the compressor contactor is becoming pitted. It was replaced today. I retained the original to return to WF. I operated the unit on second stage heating mode and recorded 30+ degrees delta temperatures across the air coil. I calculated actual heat of extraction and it is well above the printed data. Unit operating normal. Recover refrigerant from Mitsubishi mini split. 4lbs of r410a refrigerant. Replace voltage distribution system WF Geo.

Finished Heating Pm. Filters were replaced last visit. Inspected all heat exchangers. Inspected cleanliness of blowers and checked belt tension. Cleaned flame sensors and checked ignitor specs. Tested pilots and verified proper gas valve operation. Found 2 inducer motors vibrating, only needed to remove from mount and remount, unit vibration must have made them shift. Checked capacitors and contactors. Flushed out drains and poured bleach down per customer request. Called for heat and checked amperage and heat rise. Let systems satisfy thermostats. Put stats back to ac and checked operation of that as well. All units operating normal at this time.

Upon arrival I spoke with customer and he informed me that he tested all units in heat and corporate unit 2.2 on 1st floor isn’t heating. Opened up panels and found spark Igniter not lighting pilot. Can see the spark but no flame. Removed pilot tube from gas valve and verified gas is being sent to pilot. Removed burner assembly from unit then removed pilot assembly. Found pilot hood is rusty and not letting any gas flow through. Cleaned out with WD40 and blew out with nitrogen, then wiped clean. Reinstalled pilot assembly and burner assembly to unit, returned power and tested. Pilot is now lighting but hood is not letting enough gas out to have unit sense the flame, you can just barely see the flame. Removed assembly again and tried to clean but found the same results once I put everything back together. Need to replace Pilot Assembly. Called office and they said suppliers don’t have any on the shelf and it needs to be ordered.

Upon arrival I was told that previous company had diagnosed system and they would like us to do the same and give them recommendations. Went to roof and found circuit 1 ac running with 7 degree delta air temp. Shut down unit and found circuit low on R22, high Superheat and low subcooling. Need to pressurize with nitrogen to find leak, repair, then recharge. I can see oil near suction line Tee so we should start there. Put gauges on 2nd Circuit to find suction pressure dropping very low. Can feel temperature difference between pipes on filter drier. Need to replace filter drier and pressure test with nitrogen for leaks. I then inspected rest of unit and found heat exchanger cracked in several areas. Quoting customer to replace. Finally I found blower motor variable pitch pulley too far open, causing motor to overheat and not move as much air. Closed pulley to raise belt on shaft which lowered amperage and increased speed to normal rate. In total, customer needs leak search and repair do

The only issue I could find with this unit was too high of a temperature delta across the coil. The coil and filters were clean. The belt was not only loose but the pulley had been opened up so much that it could not be adequately tensioned. I used the pulley wheel adjustment to close the wheel 3 turns. I tried going 5 turns but then the belt had too much tension. I backed off until I had a good tension. Making this pulley adjustment Increases CFM. I increased CFM to the maximum amount while keeping with the B65 belt. I turned the unit back on and the airflow difference was noticeable as the temperature delta was in a normal range. This was the only problem I could find as the drain pan is not clogged and there was condensation forming on the metal inside the blower cabinet then dripping down into the duct below. I checked in and out with two different managers. I told the manager I checked out with that I could not access the duct to dry up the moisture that was already there but that

Replaced both 20x25x1 filters. A44 belt ok. Cleaned condenser coil. Evap coil and blower are clean. Checked capacitor and contactors. Tightened electrical connections. Ran ac and checked refrigerant pressures and temps. Measured amp draw of compressor, od fan, and blower. R22 refrigerant pressures low, Superheat very high, delta air temp low. Customer said that unit has been working fine for them but I suggest performing a leak search and repair, 9.2 lbs R22 system. Preparing quote for customer.

Upon arrival I was directed to Bryan, who explained that they have 3 RTUs, 1 for lobby and 2 for labs in back. He also said that they have been experiencing high humidity in lobby but they are interested in PM contract with us. I was then shown to thermostats and roof ladder in mechanical room. Went to roof and found rooftop units. Wrote down Model and serial numbers, belt and filter sizes. Found both lab units are heating and cooling at the same time. Thermostats indicate heat on, while Humidistat in returns are calling for AC to run. Per notes in both Lennox units, Humidistats located in return duct set for 50%, thermostat set to auto only in summer for heat operation to balance humidity. In short both gas furnace and compressors are running, heating and cooling to bring down humidity. Fresh air dampers closed. Operating controls indicate proper operation and customer is ok with indoor temp and humidity currently but mentioned problems in the past. I also found that left lab RTU has

Customer let me know that they needed the unit checked out. Customer signed up for service membership. I performed cooling maintenance after letting the customer know that the drips were condensation forming on the geo piping. I did as a courtesy insulate two joints which were not insulated or the insulation had cracked away from. I cleaned the condensate pan and drain lines and ran hot water to flush the debris out and to check for proper drainage and proper operation of the condensate pump. I checked the electrical wiring and electrical systems, all are within specification. I set blower speeds correctly to 2,3,10,11 from 3,6,10,11. These high speeds at low compressor speeds had resulted in some out of envelope faults. I then operated the unit on speed 9 cooling mode. Set flow rate to 10.5 gpm as was confirmed by the performance monitor. Unit operating normal. I recommended installing a whole house surge protector to the main electrical panel and also installing an Apco air scrubber

Upon arrival I found thermostat at 72, off. Customer explained that ac wasn’t going below 68. Turned on AC, put gauges on system, and checked operation. Went indoors and found filter very restricted. 16x25x1, customer didn’t have correct size replacement, had to cut 20x25x1 to size. Put filter in and restarted AC. Suction 133psi, Discharge 249psi, SH 10, SC 11, delta air temp 20 with nice condensation around suction line. Ran unit until it satisfied at 68, took less than an hour. Unit operating normal at this time with new filter. When checking out, I was also told that thermostat itself will not let them set the temperature above 68 in cooling. Found max cool temp setting at 68, changed to 80, left minimum at 64. Put unit back into AC mode and checked operation again. Unit operating normal.

Upon arrival I was told that carbon monoxide detector was going off in basement next to furnace and water heater. During diagnostics I found old carbon monoxide detector on the ground not in use and new one plugged in reading 0. I brought brand new detector from truck and plugged in as well. Inspected water heater and both furnaces because they are all gas appliances. Both heat exchangers in each furnace were in good condition, no rust or cracks. Ran hot water and made sure combustion blower turned on normally. Traced all flue piping and found no cracks or broken parts. Ran furnaces and checked operation. Found normal heat rise on both and normal operation. Neither furnace or water heater caused carbon monoxide detector to go off, bad detector. Customer has new one in place already.

I replaced the air filter with one provided by the customer. I cleaned the condensate pan and drain lines and ran hot water to flush the debris out and checked for leaks and operation of the condensate pump. I operated the unit on second stage cooling mode and confirmed proper flow rate and heat of rejection. I did pressurize the ground loop to 65 psi. I checked the electrical wiring and electrical systems, capacitor at full value and contactor is not burnt or pitted. Unit is operating normal. I recommend adding Intellistart module to help the compressor at start up and thus extend its life. It’s also important to add some manner of surge protection for the equipment. A whole house surge protector on the main panel protects everything in the home.
