Dallas TX Heating And Air Conditioning

Arrive for no cool on downstairs system. Main downstairs system is cooling correctly, getting 70° return and 50° supply temperature. System serving bedroom area is not cooling at all. Went outside to condenser and checked refrigerant pressures. System is very low on refrigerant. Noticed oily residue around reversing valve. Found that true suction line rubbed against big suction line and put a hole in it. Hole in copper line needs to be patched with solder and filled back up with refrigerant. This includes replacing filter line dryer. Install is coming back out later today to repair it.

2 system AC maintenance. Replaced filters provided by customer. Checked operation of drain lines, they are clear and I treated them with drain solution. Measured temperature drop across systems, getting proper cooling by both units. Next, went outside to condensers. Measured amp draw on compressors and fan motors. Starting amp draw on compressor for bedroom system is at its limit, any more will start to put extra wear and tear on the compressor. Recommend installing hard start kit before it gets too bad. Capacitor for bedroom system is now out of range and could fail at any point. Sent estimate to have capacitor replaced, included generic one as well as one that comes with 5 year warranty. Cleaned condenser coils using water. Systems are cooling at this time.

3 system AC maintenance. Replaced filters provided by customer. Checked operation of drain line, treated them with drain solution. Measured temperature drop across systems, getting at least 54° supply temperature for all. All systems have safety shut off switches. Next, went outside to condensers. Measured amp draw on compressors and fan motors. Starting amp draw on compressor for upstairs system is over the limit set by the manufacturer. Recommend installing hard start kit to bring starting amps down and prolong life of system. Contactors and capacitors are within acceptable range. Cleaned condenser coils using water. Systems are cooling at this time. Noticed copper line for bedroom system is kinked badly, not sure if this happened when his mulch was put in earlier this summer or if it had already been like that. Let him know it could have issues cooling and he will monitor it and let us know. Supply temperature is good at this time.

Arrive for 1 system AC maintenance. Customer just replaced filter, it is still good. Checked operation of drain line and treated it with drain solution. Measured amp draw on blower motor and checked capacitor. Blower wheel has dirt and dust buildup on it, recommend having it pulled and cleaned. Evaporator coil has biological growth and debris building up between the fins. This will lead to loss of performance and efficiency, recommend having it chemically cleaned. Next, went outside to condenser. Measured amp draw on compressor and fan motor. Checked capacitor and contactor. Capacitor is getting slightly low, recommend replacing it and the contactor to prevent any premature failure. Sent estimate for rebuild on outside unit that also includes retightening all the wiring inside outdoor unit. Cleaned condenser coil using water. System is cooling at this time.

Service Summary Upon arrival, we evaluated the reported condensation/water leak above the bathtub. System was running at 72°. Findings / Root Cause Our inspection determined that the primary cause of the condensation leak was a significant buildup of slime, dirt, and debris inside the HVAC condensation drain pan and drainage area. The system’s air filter is located in the wall, leaving an open area between the filtration point and the HVAC unit. Dirt, dust, and other debris can collect in this space and eventually make its way into the unit and condensation pan. Over time, this debris mixed with moisture and created slime and buildup inside the drain pan, restricting proper drainage. Once the condensation could no longer drain properly, water backed up and resulted in the leak observed above the bathtub. *********Did a courtesy condenser coil cleaning.************ Recommended Preventive Maintenance To help prevent this issue from returning, we strongly recommend: * Chemical

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.

Installed the new suction line temp sensor and replaced all of the filters.

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.

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.
