for Laurel, MD
Good estimate, bad scheduling
Reid - Laurel, MD
I was scheduled for a noon-4pm appointment, but the tech didn't show until 6:30pm. He was professional and provided a good estimate while there but I didn't appreciate waiting around so long.

Technician is very polite and patient.
Upon arrival I was told that pilot kept going out on customer, happened last weekend as well. During diagnostics I smelled gas in closet, shut off gas line and removed pipe to inspect it. When doing so I dropped fitting down the drain and couldnâ€™t get it back. Went to Home Depot to get new fitting. Found they are not the same and Home Depot doesnâ€™t sell adapter pieces. Had to remove male to male end at ignition module then install new female fitting, hose was ok and didnâ€™t see any cuts or nicks. Pressure tested hose and verified no leaks. Turned pilot on and made sure it stayed lit for a few minutes. Called for lowest heat setting and waited until tank heated up. Let tank satisfy then made sure pilot stayed lit again. Put temp back to B as customer requested.
The filter was recently replaced. I removed the evaporator coil cabinet and inspected the coil, which is very clean as well as the blower wheel. I cleaned the condensate pan and drain lines and ran hot water to flush the debris and to make sure it drained properly without leaks. I checked the electrical wiring and electrical systems, all are within specification. I operated the unit on cooling mode and recorded 20+ degree delta temperatures across the evaporator coil. Refrigerant pressures were normal for a system that uses r22 refrigerant. I checked for normal superheat as the metering device is a fixed orifice and it was in normal range. Unit operating normal. In regards to the furnace flue pipe that has minor leaks, the fittings must be cut out and replaced to ensure a proper seal. Customer approved this repair. I cut out 2 separate flue pipe joints and made new joints using new materials, primer visible on each joint and glue.
found blower motor not working, need to replace
Install electrical junction box above the ceiling and run new wire to the disconnect box. Install properly sized 25 amp breaker in the main electrical panel. Installed the junction box and ran new wire from inside the home to the disconnect box outside. Secured wire and sealed any places moisture could penetrate on the siding. Unit is operating. I completed a part order form for the 25 amp breaker. We will need to return to install it. The customers card is on file in the system to bill when work is completed. I spoke with the home owner after repairs were made.

On arrival set unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked water pressure,coils,cleaned drain,unit operating normal .
Replace inducer motor and fan assembly: Heater #3. Replace flame sense: Heater #2 I called BAS after checking in with the manager. I replaced the flame sensor on #2 and tested the unit. It is operating properly. I replaced the inducer motor and fan housing assembly for #3 and went to test the unit. The inducer motor now operates but the control board was damaged during the event that killed the inducer motor. I could not have tested for this without the draft motor working. The board displays a pressure switch fault even though the inducer is pulling over 2.1 iwc and the switch closes at .88. The switch itself is functioning properly. The control board has a short and must be replaced. I filled out a part estimate form with pictures of the unit and the part and let the office manager know as well. I also checked out with BAS and asked if I should turn power off to #3 and they agreed.
I operated the unit on compressor speed #12 in heating mode. Temperature rise was higher than specification so increased the blower speeds to 3,3,11,12. Refrigerant pressures were normal. I used the performance monitor to slow vs pumps to achieve 11.5 gpm flow rate which was confirmed by having 3.5 psi pressure drop. Heat of extraction is normal. I checked the electrical wiring and electrical systems, all are within specification. Customer has ordered a filter and they will replace themselves when it arrives. Unit operating normal. I spoke with the customer about the benefits of adding a nlue tube ultra violet light to kill germs and viruses and keep bacterial growth from forming on the coil. I made an estimate that I will also forward to the customer.
Will need to set up using drop cloths for crime carpet and plastic sheeting to block all around area to protect the house will also need ladder as the spot showing the leak is partly on a raised overhang above first floor living room and split level second floor dining area , estimate of approximately $253.00 to diagnose this does not include the repair an estimate to complete the repair will be given when the issue is found. Customer is responsible for all drywall repair
Fall pm On 02/18/19 On arrival set unit to call for heat measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filters and replaced units operating normal at this time.
Upon arrival I found furnace wasnâ€™t operating because condensate pump was full and cardboard safety tab wasnâ€™t removed. Removed tab and pump started running, then furnace fired up and started running. Then went to start ac and found system flashing High Side Fault, found high pressure switch wire wasnâ€™t plugged into board. Plugged in and outdoor unit started running. Finally found low voltage wiring wasnâ€™t consistent, colors changing from furnace to ac to thermostat. Made all wires consistent throughout. Tested unit afterwards. Unit is operating normal at this time. Customer also gave me paperwork to give to office for installation.
On arrival found high voltage fuse blown ,replaced it ,tested it unit operation, system operating ok .plz charge credit card on file
Customer had leak from condenasate line on tankless heater due to plastic tubing bent water was unable to drain causing it to leak out onto floor
Will return with Denny tommorow to go over the piping
BAS is closed on the weekends, I tried calling but no one is there. Manager confirmed this as well. I still trouble shot the two units. Heater #2 locked out on failure to sense 1.1 micro amps. The flame sensor needs to be replaced. Heater #3 locked out on pressure switch failing to close. The inducer motor is receiving 120 voltage but fails to operate or pull an amp draw. The inducer motor and assembly need to be replaced. I took pictures of the parts and filled out a â€œestimateâ€ part order form and made an estimate for the approximate amount of time it will take to perform these 2 repairs. Manager signed the iPad invoice and the paperwork.
Must return tommorow morning
On arrival we found outdoor unit not going into defrost mode due to a defective defrost board, we also found a bad contactor. The unit is not operating normal. Customer is calling home insurance for repair.
Upon arrival I found NEST thermostat didnâ€™t have any power. Went to furnace and found LEDs lit, furnace not running, and condensate pump running. Found vinyl tubing was routed outside and is frozen. Moved tubing to sump pump in basement. Tested condensate pump multiple times. Returned power to furnace and checked operation. Furnace operating normal. Suggest customer replace 20x20x1 filter soon.
I checked in with the store manager and then set the ladder behind the store. I replaced all units filters and dated them. The belts for units 1-6 were replaced in late September 2018. I checked to make sure the tension was holding tight and condition of the belts. No belts were replaced as they are in very good condition. I operated units 1-6 on stage 1 and stage 2 heat mode. I operated units 7&8 on stage 1 heat mode. All units operated normal. No system faults displayed on terminals. Units are clean and in good working order. I checked the electrical wiring and electrical systems. I reset each disconnect as a means to test them and before leaving the roof I went around to each unit and made sure they had power, that the panels were properly secured and that the drains were clean. All units are operating normal. I checked out with the store manager and got their signature. I let them know everything was finished and to turn the alarm system back on.
Found furnace off . BGE shut down furnace due to CO2 in the home . Flue venting has cracks and holes in it . Recommend replacing to furnace and to hot water heater . Also checked heat exchanger and found 3 deep scratches in it . I could only access top right and bottom of heat exchanger. Due to the age ( 33 years old ) recommend replacing furnace instead of just heat exchanger . Set up time with sales come out to go over system .
