Arrived to do a performance maintenance. Removed and cleaned the filter cover. Replaced furnace filter with homeowners supplied filter. Set up for combustion analysis temperature split and static pressure tests. Found that the systems gas valve was using too much gas for combustion. Tuned the gas valve to bring this within manufacturers specifications. This also helps keep the system from continuing to overheat. Verified operation of all mechanical and electronic components of the furnace. Checked blower for cleanliness and to see if there is any play in the bearings. Found that the fan for heating and cooling is heavily coated in dust debris, impeding airflow. Checked systems heat exchanger to ensure proper venting of flue gas. Found that the heat exchanger is extremely worn. The first bend in the heat exchanger is pock marked and steel seems to be flaking off the structure of the heat exchanger. Furnace is operational at this time.

@8:48 ****((**(*(******(****&&**((**** The control board was picked up and brought on-site. Before replacement I rechecked voltages to the board and the voltages were in proper range. I installed the new board and the system completed it’s ignition cycle and the indoor blower motor came on once the flames were established. The system was cycled out of heat mode successfully. His unit serves Katie’s office and in now back in service. Two temporary wind caps were made and attached to the rooftop units (s/n ending 10197 & 30291). The factory parts are on back order however they were ordered today and we are expecting arrival Sometime in the next month. The estimate for today’s work is below for reference.

Their purpose is to direct flue gasses away from the unit to prevent exhaust recycling into the burners and protect the flames from wind which may push the flames away from the flame sensor and cause the unit to lockout on a safety switch. Below is an estimate for their replacement. Once the estimate is approved they will be ordered into our shop and installed as soon as they arrive. This is a time plus material estimate for the replacement of two missing wind caps. The material cost for this repair $365.42. The time to replace them is estimated to be between 2-3hrs at a reduced rate of $139 per hour. The parts and labor used for this repair will be covered under a one year wa

Homeowner approved the duct cleaning blower clean and evaporator coil cleaning estimate.

12/11/25 - Completed the monthly filter change on all five RTU’s.

Arrived to do a performance maintenance. Set up for combustion analysis temperature split and static pressure tests. Found that the system is operating with excessive static pressure. Verified operation of all mechanical and electronic components of the furnace. Checked blower for cleanliness and to see if there is any play in the bearings. Found that the fan for the furnace is collecting dust. Checked systems heat exchanger to ensure proper venting of flue gas. Found that the heat exchanger is heat stressed and rusting, indicating that it overheated at some point. Furnace and operational at this time.

12/10/25 - Completed a light heating maintenance on four RTU’s. The filters were changed and operation was tested. RTU 3 still has the gas shut off due to a previously diagnosed cracked heat exchanger, so it is currently not heating at this time. Other than that, the rest of the units are heating well at this time, they were in good condition, and there were no further issues found at this time.

Quote for replacing flue or water heater

Went for a service call today. Checked error codes on board. None were displayed and all cleared. Temp split passes for system. All electrical components are passing for manufacture specifications. Cleaned out pressure switch hose and cleaned flame sensor. System is up and running before leaving. Signed up customer for membership and trip fee was waived. Thank you for choosing LBA services-Johann

Humidifier stat wasn’t set for it to be on. As well humidifier was set on summer did adjust for winter. Tested multiple times and was operating every test. System is up and running before leaving. Thank you for choosing LBA services-Johann

Today I diagnosed a failed control board on rooftop unit #4. In addition to this the wind caps for this rooftop unit and the one next to it are missing. When I arrived the unit was shut down on an internal safety switch that had been tripped and was not heating at all. The unit was intermittently turning the gas valve and inducer on and off while a constant signal from the thermostat for heating was present at the failed board. An estimate for these repairs was created and emailed. The replacement control board was sourced, is available locally and is a factory direct part. Unit#4 and the rooftop unit directly to it’s north has missing wind caps. These prevent the flue gasses from recirculating into the combustion compartment and also prevent the wind from blowing the flames around that may cause the units to lock out on a safety switch. An estimate for both of these wind caps has been sent via email. Thank you, Jon Tech notes: Rooftop unit #4 S/n ending 0197

Arrived to do a performance maintenance. Set up for combustion analysis temperature split and static pressure tests. Found that the furnace overheated before finishing these tests. Increased the furnace fan speed to allow me to run the system long enough to finish testing. This in turn increased the systems static pressure, but kept the operating temperature closer to manufacturers specifications. Verified operation of all mechanical and electronic components of the furnace. Checked blower for cleanliness and to see if there is any play in the bearings. Found that the fan for heating and cooling is heavily coated in dust debris. Checked systems heat exchanger to ensure proper venting of flue gas. Found large hot spots and other signs of extreme wear and overheating on the heat exchanger. While checking the heat exchanger turned the inspection camera around and found that the evaporator coil is impacted with debris, further impeding airflow. Furnace is operational at this time.

This task will be getting rid of the galvanize and cast iron pipe that runs to the toilet and shower. We will tie back onto the pvc and most likely will have to caught out drywall and we do not out drywall back.

Went for a maintenance call today for heat. Tested for static pressure system is max when in heat. All electrical components are passing for manufacture specifications. Did a combustion test is within range. Inspected heat exchanger no cracks/leaks were detected. Checked temp split and is passing. Did replace filter for customer. Cleaned flame sensor and pressure switch hose. System is up and running before departure. Thank you for choosing LBA services-Johann

Installed new furnace and t-stat

Arrived to remedy an inoperable system. Upon arrival found that the systems inducer is clogged with condensation from the furnaces exhaust. Cleared some of the condensation and turned on the furnace. Once condensation is cleared the system will start but will accumulate more condensation as it runs. Found that the collector box is also leaking flue condensation. With all the condensation backed up inside the furnace determined it would be safe to check the furnaces heat exchanger and make sure the system will be safe to operate. Found a hole in the heat exchanger as well as the failed gasket between the primary and secondary heat exchanger. This makes the furnace unsafe to operate. Reached out to a field supervisor to provide repair and replacement options. Signed red tag with homeowner. System is inoperable at this time.
