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.

Upon arrival I spoke with Manager Mark and he informed me that back office area was hot the other day but system was reset and has been operating normally since. Called Property Management company and spoke with Vanessa, I checked in with her and she transferred me to Phillip with the BAS system. Per Phillip, RTU 8 was the unit with problems the other day but is currently satisfied. He overrode the unit and called for ac. We checked operation and found no problems. He then asked me to find remote indoor sensor and checked temperature. Found indoor temp at sensor reading 69.6 degrees, setpoint for 70 and unit currently at 70. Phillip said all other units are either satisfied or close to satisfying. He told me to inform manager that unit is operating normal and for him to call back if indoor temp rises again.
On arrival set unit to call for cooling measured supply and return air temp . Covered evaporator lineset hole.checked refrigerant pressure .unit operating normal
System running good, cleaned filter, contactor burnt, customer agreed to replace, system still running good. Customer interested in duct cleaning service, gave estimate and customer will contact office to schedule. iPad wonâ€™t scan check, have payment.
Upon arrival found auxiliary pan completely rusted out and leaking water through roof, drain lines do not have downward slope and have hard 90s instead of a trap, quoted customer for total rehab of condensate system. AC system is at least 15 years old. Advised customer think about new system instead of costly repair to replace system. Wants to talk to salesman about pricing.
On arrival the thermostat has error code E5 low air flow I reset the unit the unit is comes on but is going back off gave me same codes checked electrical connections checked air filter checked everything but is not operating normal I call tech support for calmate Master I checked everything with the technician I found the unit low on charge I checked if has any leak no leaks I charge the unit with less than a pound changed the air filter checked electrical connections checked voltage and amps checked compressor capacitor measured supply and return air temp unit tested unit operating normal at this time. No charge for this trip.
I replaced the electronic expansion valve and bi flow filter drier. I pressurized the system to 250psi and let hold that pressure for ten minutes. I then used that nitrogen to flush the lineset from high to low. I installed all new valve stems and then pulled the system into <500 micron vacuum and charged to factory specification with new r410a refrigerant, 8lb 4oz. I tested the units operation. Normal refrigerant pressures and 20+ degree delta temperatures across the evaporator coil. Customer paid balance of the repair.
On arrival removed existing Ac breaker and installed new 25 amp breaker per work order.unit is operating normal at this time
Performed ac pm on all units. Cleaned outdoor coils with high pressure spray. Replaced all filters. All belts in good condition. Inspected Evap coils and blowers. Flushed out drain pans and traps. Checked capacitors and contactors. Tightened electrical connections. Ran ac. Measured amp draw of compressors, od fans, and blowers. Checked delta air temps at all coils. Found Unit 5 run cap out of spec. Found Unit 4 condenser fan motor not running when being supplied voltage. Quoting customer.
Replace 2 main valves above and below meter in basement
On arrival system was not cooling, outdoor unit short cycling on low pressure switch, system pressures normal when operating in heat mode. Test opened eev and removed step motor system pressures normal. Eev found to be at fault. Need to order WHOLE EEV ASSEMBLY AND SENSORS. Unit not operating in cooling mode.
Upon arrival I found thermostat reading service needed but says no faults recorded. Went to unit and found system flashing lockout but only code registered was 8, UPS warning, which doesnâ€™t translate to a lockout code only a warning of a short period in which unit was running inefficiently. Checked all wiring and components and found nothing out of place. Reset fault and ran system. Checked all parameters and found normal air flow, normal delta air temps, normal water flow, normal delta loop pressures and temps, normal amperage and Voltage. System is operating normal and I cannot determine why it locked out. Once reset unit ran perfectly normal. Asked customer to call us if they experience a similar problem.
On arrival checked thermostat was calling for cooling. Measured return temperature, supply temperature, amps, voltage, and capacitor. Inspected electrical connections, filter is clean, cleaned condensate drain line, blower wheel is clean, evaporator coil is clean, and contactor is ok. Unit is operating normal at this time.
Warranty call on 04/24/19 On arrival turn off the power supply take out the blower motor replaced it. put the new blower motor tested start up checked electrical connections checked voltage and amps measured supply and return air temp unit began operating very smoothly without any hesitating. Unit operating normal at this time.
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.

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.
