for Laurel, MD
Derrick - Laurel, MD
Price quoted by tech to unclog a condensation pipe was unreasonable and not consistent with industry pricing. But was able to negotiate a more reasonable price with supervisor after reviewing charges.
Theresita - 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.
wothwhile service plan

Upon arrival we spoke with manager, he informed us we need to get access from security company. Walked over and called number on door and they unlocked the sprinkler room for us. Recorded model and serial of 4 RTUs and 1 makeup air unit. Documented filter and belt sizes.
I ran unit in cooling mode. I checked electrical wiring and system. I cleaned condensation drain line and trap. It was a lot of sludge in the lines. Unit has a hard start kit already installed unit is operating at normal capacity this equipment is eight years old. I recommended to customer to get indoor outdoor coils clean. Due to sludge buildup in condensation drain also did a courtesy check of hot water heater no corrosion no signs of leaking everything is good. Also recommend service for texting so house check airflow delta T 59 return 72
When I arrived I turned thermostat on to call for cooling. So I can pump down system Freon back into Compressor so I can get ready to remove coil to remove drip pan from coil. Remove coil and crack pan install new pan reinstall coil...brazed in unit check for leaks with nitrogen put system on vacuum release Freon in system call for cooling delta T 57 return 73 everything Done.
When I arrived I checked furnace and and I noticed water dripping on the floor I remove cover saw that the coils is dirty and need to be clean I noticed the condensation pump was not working recommended to the customer options on a new condensation pump I also gave options of getting coils clean presented everything to the customer. And he sign for new condensation pump installation also customer sign for coils to be clean as I started to clean coils I noticed two cracks in condensation drain pan. I presented this to the customer right away gave Alex a call to get information on ordering a new drain pan percent pricing to customer. customer paid half down on condensation pan customer wants pan install tomorrow morning.

Upon arrival I cut 2inch pvc flue out that was connected to furnace. Cut open intake hole from top of furnace. Connected 3inch pvc pipe to coupling, then 2ft of 3inch pipe, then 3x2inch reducer and connected 3inch pvc to furnace flue adapter. Screwed intake adapter to top of furnace. Then piped in 2inch coupling to 3ft of 2inch pvc and connected to furnace intake adapter. Used high temp silicone around intake while all pvc was primed and glued. Tested operation.
I replaced disconnect switch for RTU #2. I checked in and out with BAS and manager on duty. Philip from BAS to send 2 phase monitors to the store to be replaced on RTU #2 & #4. I was asked to disconnect phase monitor on RTU #2.
PRESSURE NITROGEN AND CLEANED UP Service call on 08/22/19 On arrival water is dripping out from the Evaporator coil cabinet also water in garage floor I open the Evaporator coil cabinet checked the Evaporator pan is full of water the drain line is clogged I checked all drain connections some of them loose behind the house also the drain line is to long I gave quote for customer to clean drain line pressure the drain line attached the loose pipe connections customer accepted the quote pressure nitrogen connect the drain line tested with water is moving out normal checked electrical connections checked voltage and amps checked air filter measured supply and return air temp checked condenser unit outdoor checked electrical connections checked compressor capacitor checked coil measured pressure and temp and they are ideal indicating zero leaks unit operating normal at this time. Collected $425 for drain line cleaned.
Upon arrival I was told that unit wasnâ€™t running at all. During diagnostics I found system locked out on RPM/Airflow fault. Found lockout condition doesnâ€™t send voltage so I couldnâ€™t diagnose without resetting system. Once system reset, blower motor came on and was running at fan only speed. Waited until compressor delay was off then ran ac, fan increased speed and then again for 2nd stage. Measured delta air temps and checked every register. Found no airflow restrictions, filter and coil are clean. Checked return and supplies and found no issues. Delta air temp at Evap coil is 24 degrees. Suspecting intermittent faults with blower motor, quoting customer to replace. Customer declined at this time, will monitor the system and let us know.
I filled in parts order form. I spoke with dispatcher. We need to return with the parts to finish flue piping. Unit is operational now.
08/09/19 On arrival turn off the unit from disconnect box recover the refrigerant take out old compressor put new compressor breeze it tested with nitrogen no leaks vacuum the unit to 550 microns no leaks recharging the unit with 410A 8lbs and 10 oz tested start up checked electrical connections checked voltage and amps measured supply and return air temp measured subcooling and superheat unit operating normal at this time. Collected balance for the job $1430.25 on Check #570
I checked in and out with store manager and BAS. I went on the roof and found a leg of the power had voltage but it was dropping voltage. I removed the cover to the disconnect panel and found where the disconnect had burnt. I turned power off, even though the phase monitor was keeping the unit from operating. I took a picture of the part. I made a part estimate form and a quote sheet. I looked the part up with the numbers provided and it is easy to find. The office needs to finalize the quote ASAP and submit to corporate for approval. RTU #2 is not operational.
On arrival customer informed me that unit froze up then they turned power off .i then restored power back on ,unit flashing 10 code .unit started normal .checked pressures ,checked blower ,i then called tech support and advised me to change top circuit board with part number:cnt07750.

Upon my arrival I noticed the house has 3 zones. I checked the operation of the zone damper on zone 3, the one in question. I found proper air flow out of one vent in each room, and realized that the other floor vent in each room was a return air duct as there was no air pushing out. I also confirmed this with a visual inspection. The package unit was cooling with 20+ degree delta temperatures across the evaporator coils. Customer replaces the filter normally. I checked the electrical wiring and electrical systems, for potential problems and found the run capacitor was 35% depleted and that the ground loop needed pressure. Customer signed up for service membership, but I did not do a maintenance but I did pressurize the ground loop to 65psi. I replaced the 45uf run capacitor and tested the unit again. Unit operating normal. Customer has the 2 maintenances to schedule. Customer wanted to put the membership payment on a separate card so I have that information on the paperwork to turn

If freezing up again we have to replaced the temp sensor no payment collected customer needs to talk dispatcher from the office.
Upon arrival was informed rtu 6 was having issue with duct smoke detector, verified sensors getting voltage and cleaned sensing tubes, restarted system and verified system not sending any alarms and operating normal.
Checked condensate line. Found the line sealed properly.
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.
