Smithville, TX

Performed replacement of basic, refrigerant pressure control as quoted on previous trip. Replaced pressure control, filter, dryer, and recharge system to factory spec with 2.5 pounds of R410a. (System was pumped down on previous visit.) acquired 10° sub cooling and 21° delta T.

Upon arrival we checked into the concern that the comfort controller was blank and system not operating. During diagnostics we noticed the 5 amp low voltage fuse was popped. No obvious low voltage short. Used a resettable 5 amp fuse and jumped thermostat wires to trigger operation and fuse did not pop. Replaced blown fuse with new 5 amp fuse. System started up and ran without blowing fuse. Checked system pressures and it is operating at manufacturers specifications.

Upon my arrival, I performed the approved repairs. I recovered all refrigerant from the system for proper disposal, purged with nitrogen while brazing, repaired the leak on the bypass tube for the refrigerant pressure control, installed new filter dryer, pressure tested with nitrogen to 360 psi, installed performance enhancement system, evacuate nitrogen, then put the system into a vacuum. I performed a triple evacuation service breaking with nitrogen and bringing down to a vacuum three times to verify all moisture and contaminants are out of the system. After obtaining the proper vacuum on the system, I installed acid preventatives and recharged to manufacture specifications. I then turn the system on for performance and safety testing to finish out charging the system to the proper sub cool value as well as verifying proper amp draws on the system. I found everything operating within the manufacture specifications at this time.

Upon my arrival I performed a 6 month checkup on 2 heat pump systems. Flushed and treated the water removal systems, washed condenser coils using water, cleaned and treated the electrical cabinets with electrical insecticide then verified system safety and performance. I found the upstairs system operating to within manufacture specifications at this time. The down stairs unit I found it showing signs of low refrigerant charge. I spoke with the customer about adding refrigerant and he approved to do so. As I started to add refrigerant I found that the low side pressures became very high, superheat dropped very low and the sub cooling stayed the same. I quit adding refrigerant at this point and found that the refrigerant pressure control is not metering refrigerant properly. I went over my concerns with the customer and the age of the equipment. He is going to have to think about what he would like to do and is currently going to limp the system along. I did not charge for the refrigera

Performed complete system cooling evaluation. Found unit with less than desirable temperature differential and in adequate subcooling and superheat due to age and condition. Briefly discussed with homeowner, and he is fully aware that system is not operating to a high capability. System replacement will be needed in the near future. Customer renewed comfort one.

Performed single system cooling valuation on straight cool down flow split system. Found unit in good working order and operating within manufacture specifications at this time. Recommend keeping vegetation away from condensing unit outside to allow for better airflow and less vegetative buildup inside condenser.

Upon my arrival I performed the UV leak dye search. I found a leak present around the bypass tube for the refrigerant pressure control. In order to verify exactly where the leak was at given the area it was in I whipped away the uv dye and sprayed the area with soap bubbles. The leak is coming from where the bypass tube is brazed into the suction line. Customer was not present at the time of the leak search but we did speak over the phone. I will get the repair options emailed over and follow up Monday to answer any questions about the options. System does still have good charge in it at this time.

Performed die leak search and found die present at thermostatic expansion valve. Brass cap has a crack and is leaking. Performed system recovery of refrigerant remaining in system and shut down king valves. Homeowner opted for option HI2B. Parts are on order from RMI San Antonio.

Upon my arrival I evaluated 1 Heatpump system. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. Found no issues.

Upon my arrival I performed 6 month checkups on 2 heat pump system. I flushed and treated both water removal systems, washed condenser coils using water, cleaned and treated electrical cabinets with electrical insecticide, installed new refrigerant caps on both systems then verified systems safety and performance. I found unit #2 to be low on refrigerant. I charged the system to the proper sub cooling value using 2 lbs of R410a refrigerant. The refrigerant will be included with the previous repairs with no additional charge. I also noticed that the systems were set to 70° for cool and both displayed an indoor temp of 67°. After checking the comfort control settings I found the systems were set up for dehumidification when they are not equipped to do so. I turned the function off and they will monitor if it continues to come on for cool when the demand is not about the set temp.

Upon my arrival i performed a UV dye leak search with black light. During my leak search I found that there is a leak coming from the bypass tube for the refrigerant pressure control. Given the customer is not onsite today I will email the options over and follow up with any questions they may have concerning the options.

Upon my arrival I evaluated 1 mini split system. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. Found no issues.

Upon my arrival I performed a 6 month checkup on 1 heat pump system. Flushed and treated the water removal system, washed the condenser coil using water, cleaned and treated the electrical cabinet with electrical insecticide, replaced the air filter then verified systems safety and performance. I found that the system is at max amps on start up and there is no power protection on the indoor or outdoor systems. I recommend having a performance enhancement system installed to bring the start up amps down to a better performing standard and allow for a longer compressor life. Power protection is also recommended to protect the indoor and outdoor systems from any voltage spikes, power outages or brownouts. Customer would like these options emailed over so she can talk with her son who is her financial adviser. Air purification is not something the customer is interested in.

Upon arrival, I spoke with Cordelia and explained that I would be cleaning the indoor heat exchanger and airflow distribution system, and replacing the hard start kit and voltage enhancement system on the outdoor unit. I cleaned the airflow distribution system and indoor heat exchanger using Viper coil cleaner and a high-pressure washer. I also cleared the drain lines with CO₂ and inspected the wiring—no issues were found. At the outdoor unit, I removed the fan and top cover, cleaned the coils inside and out, then reassembled the unit. I replaced both the voltage enhancement system and the hard start kit. After powering the system back on, I performed a performance and safety test. Pressures were still below manufacturer specs, so with Cordelia’s approval, I added 2 lbs of R-410A. A second test showed improved performance. I advised Cordelia that if pressure issues continue, the next step would be a leak search. She agreed.

Upon my arrival I found that the system had completely defrosted. I then tested the system and found that the 27 year old system was low on r-22 refrigerant. I spoke with the client about their different options and they wanted me to give them some options for replacement which I did. The client will let us know if they want to move forward with replacement.

Upon our arrival performed approved repairs. Installed new voltage enhancement system, introduced die to system added 2 lbs of R410a and ran performance and safety test on the system. UV die leak search will be scheduled 1 to 2 weeks from today.

Upon arrival, I checked in with Robert to inform him that I would begin work on the upstairs condenser. I replaced the lower control board and the suction line temperature sensor. After completing the replacements, I performed a full performance and safety test. This included checking the amperage draw on both the refrigerant pumping system and the condenser exhaust fan—both readings were within normal operating ranges. I also measured the inlet and outlet air temperatures on the indoor unit, with a resulting temperature differential (ΔT) of 22.3°F, which indicates strong cooling performance. While evaluating the system, I noted that the refrigerant pressures on the outdoor unit were slightly lower than typical. I discussed this with Robert and Linda, and they decided to monitor the system’s performance over the next few months before taking any further action.

Upon my arrival I evaluated 2 mini split systems, each system has 2 indoor units. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. Found the airflow distribution system dirty on the found indoor units. Recommend a cleaning of the airflow distribution system. Michael approved a the quote HK11A and he also payed a deposit. Our office will reach out regarding scheduling.

I spoke with Sophie regarding her HVAC concerns. She reported that the downstairs system was not cooling properly. During troubleshooting, I found that the outdoor unit’s exhaust fan motor was drawing excessive amperage. The fan’s full load amperage (FLA) rating is 2.0, but it was drawing 4.45 amps. I verified that the voltage enhancement system was functioning correctly. However, when the motor was energized, it produced a humming noise and the shaft failed to spin, indicating a locked rotor or mechanical failure. I presented repair options to Sophie, and she chose the “band-aid” solution to replace the exhaust fan motor the same day. After completing the replacement, I performed a full performance and safety test. The system is currently operating properly. I also noted that the refrigerant pumping system’s amperage is approaching its rated running load. Due to the age of the system and the use of R-22 refrigerant (which is now obsolete), I advised that if any future issues arise

Upon my arrival I evaluated 1 heat pump system. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. Found the airflow distribution system and the indoor heat exchanger very dirty I also found the outdoor voltage enhancement low, and the pressures on the condenser were lower than the manufacturers specs. I’m going to recommend a cleaning of the indoor unit as well as an estimate to install a uv light to help keep the system clean, I also recommend replacing the outdoor voltage enhancement system and I also recommend adding refrigerant to the system. I also found zooglea im the primary drain line, I’m going to recommend iFlo to maintain the drain line clean. The office will email the quotes and I’ll give a call shortly regarding the repairs.

Cleaned the electrical cabinet and washed unit using water. Found the voltage enhancement system for the outdoor unit low and the pressures on the outdoor unit were also low. . Recommend replacing the outdoor voltage enhancement system and adding r410a. I was approved to add r410a and only needed to add 2lb’s I was also approved to do a complete voltage enhancement system renovation where I replaced the voltage enhancement system voltage distribution system, installed a hard start kit and did a performance and safety testing.

Upon my arrival I performed a 6 month checkup on 1 package straight cool furnace system and 1 straight cool traditional split system. Flushed and treated the water removal system, washed the condenser coils using water, cleaned and treated the electrical cabinets with electrical insecticide the verified systems safety and performance. I found both system to be operating within manufacture specifications at this time. However both systems are in need of a cleaning on the heat transfer media coils. I spoke with the customer about Solaris and cleaning options. Given she plans to sale the home sometime next year she doesn’t wish to install Solaris but would like to go over the cleaning options again at her next visit since she’s about to be out of town for a couple of months.
