Service Findings The upstairs Lennox HVAC system has experienced an intermittent communication alert at the thermostat. At times, the thermostat may temporarily lose communication with the indoor equipment. At this time, the HVAC system continues to operate and function properly, even when this communication alert occurs. Lennox Technical Support We contacted Lennox Technical Support to review the communication alert and system behavior. Based on the information provided and the alarm history, Lennox Technical Support indicated that the issue appears to be related to the existing thermostat/communication wiring between the upstairs indoor unit and the thermostat. Recommendation Since the system is currently operating properly, no immediate wiring replacement is required. However, if the communication alert returns or becomes more frequent, Lennox Technical Support recommends: * Replacing the existing thermostat/communication wire. * Installing a new continuous wire from the up

Performed one system maintenance. Found the outdoor outdoor unit was restricted with debris. I found that drain line was clogged, causing float. Switch to periodically trip. I lightly rinsed condenser with water hose for maintenance. And cleared drain line, drain line is now clear. System is running properly at this time. Left estimate to replace suction line temperature sensor.

Upon arrival I found that outdoor unit was low on refrigerant, causing condenser to short cycle. It was going out on low pressure. Found a lot of oil spots on outdoor condenser and with the electronic leak detector found a leak on condenser coil. Reserved a condenser coil at the Carrollton location ready for pick up.

I performed a single cooling maintenance on a 2022 gas system. I investigated the concerns about all the moisture spots. The ceiling is becoming damage around grills due to poor attic insulation. The water outside is the primary drain for the system. During my thorough evaluation, I noticed a couple of other issues. The drain needs to be revised to allow treatment to reach the ptrap and the vent does not have a pipe to prevent overflow. The outdoor capacitor is almost out of range and needs replacement soon. The blower wheel has a build up on it and needs cleaning. Also, there is a duct in the attic that is missing insulation at one of the elbows. This will produce condensation and cause damage. I provided pricing to address all of these concerns during the time of visit.

2 system AC maintenance. Customer did not have filters and he will get them ordered to replace them. Checked operation of drain line and treated them with drain solution. Measured temperature drop across systems and both are cooling correctly. Measured amp draw on blower motors, compressors, and fan motors. Checked contactor and capacitor on downstairs unit, upstairs system does not have either. Clean condenser coils, using water. Systems are cooling at this time.

Customer had concerns of water dripping from panel below unit. After removing panel, found that drain line was clogged and causing water to overflow pan. Clear drain line using nitrogen. Verified that all water from drain pan drained out properly. Tested system operation after repair. System is cooling at this time.

Arrive for no cool. Indoor blower was on but condenser was not. 40 amp breaker in disconnect box was tripped. Found that run capacitor had failed, this had also caused the hard start kit capacitor to fail. Replaced both under parts and labor warranty. Surge protector is active and working. Tested starting amp draw on compressor. Tested amp draw on compressor while it was running, it is operating within manufacturer specs. Measured temperature drop across system, getting 19° difference. System is cooling at this time.

No cool on upstairs system. Set thermostat to cool, indoor blower came on but air was not cold. Checked condenser and it was shutting off on high head pressure because fan motor was not running. Capacitor had failed. Replaced it using Turbo capacitor that comes with 5 year warranty. Tested system after repair. Checked amp draw on compressor and fan motor. Measured temperature drop across system, return 81° and supply 60°. System is cooling at this time.

I performed a quality check on a new installation. I went over the functions of the thermostat with the client. I tested the drain line to ensure it was performing properly and that the float switch is operational. I checked refrigerant pressures and temperature differential. I tested the system in heating and cooling. The client mentioned the new return grille is whistling. I adjusted the pitch of the fins to address the whistling. The system is performing well and the connections are sealed.

Master bedroom thermostat had an error on screen that was preventing the customer from using it. Downstairs thermostat was able to control the equipment and get it cooling. Pulled upstairs thermostat off the wall and checked voltages. Getting correct 12vdc at wall mount. Let thermostat completely power off and reconnected it. Once it powered on, error message went away and thermostat was able to be adjusted. System is cooling at this time. Filters need to be changed, customer is ordering them online. Size for both: Aprilaire 410

Upon arrival I found that system was cooling. I checked supply and return temperatures. It was cooling down 20°. Return was pulling in 79° and supply was putting out 59°. Drains had no indication of any cloggage. There was no water in the emergency drain pan. The air filter was not dirty. I went to outdoor unit and found that start. Capacitor was weak below the 5% manufacturers specs. I replaced the 30/5 star capacitor and system is running properly at this time. House was at 80° when I got here it was at 79° when I left. Thermostat was set to 77.
Shelby S.
Upon arrival, I found the fan running without the compressor outside. I opened the electrical panel and discovered a bloated 45 capacitor causing the compressor to not start. With customer approval, I replaced the capacitor and tested to ensure it was back to cooling. Refrigerant pressures are kind of high but it is 84 in the house and a feel like of 100 outside. The system is cooling upon departure.

I found the breaker off for the unit. I turned it back on and the system began cooling again.

I performed a 3 system cooling maintenance on equipment that are ages 2018, 2018, and 2024. I checked amps, capacitors, filters, electrical, drains, cleanliness, and safeties. During my thorough evaluation, I noticed that 2 of the 3 outdoor units need chemical cleaning to better their performance and limit the stress on the electrical components of the systems. I observed that the equipment does not have surge protection leaving them susceptible to damage from electrical fluctuations. I provided options to address these areas of concerns during the time of service.

I performed a single cooling maintenance on a 2016 gas system. I checked amps, drains, electrical, cleanliness, and safeties. During my thorough evaluation, I noticed that the contactor is becoming worn and could use replacement soon, and I requoted the leveling for the system. I noticed that there was an oil spot on the outdoor unit. After investigating, I believe that it happened when doing the TXV replacement on the system. The system is cooling upon departure.

Upon arrival, I discover that the refrigerant pressures were not correct. I proceeded under the house and opened the evaporator coil to see if the evaporator coil was dirty. I found that the evaporator coil is frozen at the TXV indicating the TXV is bad. I checked warranty on the system and verified that it is out of warranty. I reached out to shear supply in Allen about a TXV. They informed me that if we do not order before 2:30 that it will not be until Monday that the part will be available. I could not get in contact with the landlord and emailed the pricing, dispatch fee, and pictures. This issue could not have been found during previous visit due to the system being frozen up from an extremely dirty filter.

Air scrubber installed at today’s visit. Upon completion of my thorough evaluation I found that upstairs unit doesn’t have an air scrubber like the downstairs, by adding the air scrubber you can help catch more dust and combat against more allergens for the whole home.

Upon completion of my thorough evaluation of one split unit and mini spilt. I tested all electrical components on the inside unit. All tested within manufacturer specifications. I treated drain lines with totalc and water. I changed filter for the client. Aprilaire 210 20x25x4. Temperature being supplied to the home was 55 degrees and return was 75 degrees. I rinsed the mini split filters with water. Tested all electrical components on the mini split all tested within manufacturer specifications. I tested all electrical components on the outside unit for the split system. All tested within manufacturer specifications. The capacitor is testing a little lower then specifications but is in good working order. I rinsed both units with water. Units cooling upon departure.

Upon completion of my thorough evaluation, I tested all electrical components on the inside units. All tested within manufacturer specifications. Both units take a Aprilaire 213 filter. Both were changed at today’s visit, the client did state that he was noticing more dust on them and having to changed them more frequently. The downstairs system has an air cleaner on the system and causing the dust particles to clump together and this means the air filter will catch more. However the upstairs unit does have some dust build up on in the ducts and could benefit from having a duct cleaning preformed. Also there isn’t an air scrubber installed on this unit. So they filter wasn’t as dirt as the other. I treated and tested drain lines with totalc and water. On the outside units I tested all electrical components and all were testing within manufacturer specifications. I rinsed he out side units with water at today’s visit.
