Clayton NC Heating & Air Conditioning Services

Tech performed esa, tech found hardstart kit testing outside of specs and recommended replacement, customer declined at this time, system is back on and operating properly at this time.

Tech performed esa on one system. Tech did not find any issues with system operation at this time. Tech found that evaporator coil is rusted but did not detect any leaks at this time. Tech informed customer of age and condition and recommended that customer think about replacement. All is good at this time. Tech did not have 12x24x1 filters.

Fix hood and replace

Performed CMA Inspection on 3 split heat pump systems and 1 mini split heat pump system. All electrical tested within acceptable range. Filters change and/or cleaned. No challenges present today. All systems cooling properly with temperature changeovers between 18-20 degrees.

Tech returned to further diagnose RTU#4. Found blower door panel for RTU #15 (serial 538L) fallen off. Secured panel with new screws. On RTU #4, Lennox RTU (serial 1828) tech traced Y2 circuit. Tech found high pressure switch for forward (Y2) compressor electrically open. Tech bypassed high pressure switch for testing purposes. High pressure switch for the other compressor Y1 has already been bypassed prior to today's visit. Both circuits ran, but fan motor further away from disconnect did not run. Tech found common wire fallen off of fan motor. Plugged fan motor back in and tightened all 3 spade connections. Both fan motors are wired to run together all the time. Both circuits are now running when called with both fan motors running. Tech allowed system to stabilize and recorded Y2 refrigerant pressures. Tech also noticed that data tags for both fan motors call for a 12.5uf fan capacitor. There is a 15uf installed. It is reading 7.2uf. The 12.5uf capacitor for the other fan motor is

Upon arrival tech found condenser not running, after inspection tech found tripped float switch from clogged drain. Tech cleared drain and added union, also spoke to customer about EZ Trap drain for better drainage. Customer signed up for MSA.

Thermostat satisfied at 73 upon arrival. Stated system has been working properly as of the past day. Cycled system up to 2nd stage with no challenges. Amp draws/pressures within specs. Changeover of 20 degrees. Compressor amp draws slightly high at 10.5A due to clogged condenser coils. Intermittent challenge may be present, but unable to duplicate any issues during today’s visit. Invested in PSA (1) system. Schedule 1st visit.

- RTU #15 Tech found disconnect shut off and restored power to test operation. Confirmed compressor is not grounded and measures in the green zone on megohm reader. System is operating normally and did not trip the fire alarm after 3 hours of cycling. - RTU #2 Tech found compressor disconnected from contactor on load side. Found compressor megohms reading in the red zone on all three terminals. Tech ran system to test operation and found compressor malfunctioning with suction pressure dropping below zero and discharge pressure at 202.3. Tech reversed phase power on load side of contactor to test compressor running backward and observed blower running in reverse. Confirmed faulty compressor after reviewing metering device, evaporator coil, and proper air flow. System is not equipped with any liquid line solenoid valves. Compressor must be replaced before system operates normally. Recommended system replacement on account of age and cost of repairs. - RTU #4 Tech found circuit #1 oper

Sealed condensate tubing in pvc entering and exit. Installed French drain at exit. Condensate pump is working correctly

RTU 3 - upon arrival, circuit 1 was disconnected at the compressor. No information available as to why this is the case. Technician Megohm tested the compressor and found the winding to be in the BAD range. Additionally, the evaporator coil is very rusted. No leaks could be pinpointed at today’s visit. Temperature change over is around 12-13 degrees, and system is running at 1/2 capacity with circuit 1 being down. Turned over to field supervisors office to discuss options with customer. RTU 15 - system shut off at disconnect when technician arrived. Per customer, this system has had issues in the past regarding the fire alarm. Technician checked what components they could and everything tested within spec. Compressor is in CAUTION range but nothing is indicating that it would not work. Coils do show some rust, no leak could be found today. Tech would recommend having a service tech come out to further diagnose the challenges regarding the fire alarm system. RTU 2 - Upon arrival the t

Performed ESA, tech found no issues at todays visit. Tech jumped out heat and found heat to come on without any problems. Cleaned and serviced downstairs system only.

Performed ESA, no issues found at todays visit. Both uv bulbs need to be changed out. Recommended plasma air purifiers inside. Homeowner stated next visit he would like to have them installed possibly. Both systems are back on and cooling.

Tech washed and serviced both units and found no challenges at this time. Both sys are up and cooling with a delta t within specs at this time. Tech recommended plasma air for better air quality and to help with mildew build up. Customer would like to wait and speak with spouse.

Tech washed and serviced unit and found capacitor to be testing at 40.9 when rated for 45mfd tech recommended replacement customer would like to wait for now. Customer invested in psa monthly u it is up and cooling properly at this time.

Performed CMA filter change and also replaced Slim Lime Mini Split Condensate Pump. After pump was replaced, technician tested several times without issue (video provided). Customer billed out for repairs. And invoice sent to email on file. Main contact Johnny Scott was not available today, assistant pro signed for work completed.

System was cool ign upon arrival, Tested the zone system system and noticed high static pressure as the system operated with one zone closed. Tech checked the damper motors for proper operation. Found the system shutting off the condenser on low temperature cut off. Found filters extremely clogged. Tech Replaced the filters and tested the system in cool mode again and zone temperature was now maintained at 49-50 degrees instead of 40 degrees(low temperature computing out). Customer approved replacing the filters. Tech recommended installing a plasma air purifier to help with dust and bacteria control. Customer requested an estimate and will go over it with her husband to make a decision. System is back cooling.

Emailed proposal. Customer is getting multiple quotes.

Tech washed and serviced unit and found no challenges at this time both systems are newer. Customer extended psa 2 sys via check. Both units are up and running with a delta t within spec.

Took pictures for sales proposal

Install light switch

Upon arrival tech found system very low on refrigerant. Performed leak search and located leak at evaporator coil. Built estimate for leak repair, we will need to verify warranty once able to when office opens back up and manufacture opens up. Call customer to verify if system is under a 10 year warranty or not, customer will make decision on fixing leak or replacing coil at that time.

Upon arrival tech found system low on Freon. Added 6lbs of R410A to get system properly charged. Performed leak search at 4 service ports at condenser with soap bubbles and found the schrader valve on the liquid line leaking. Tech replaced with new. System is back operational.

Upon arrival tech was informed system 2 and system 3 did not seem to be working. Tech found both thermostats flashing to reset date and time. Reset and thermostat came back on. Tech found all 3 systems running. System 2 delta T was in an ok range but pressures indicated system was a little low on Freon. System 1 and a ok delta T and pressures were ok. All 3 system are 20 years old and R22 Freon. After speaking with manager they would like to start getting quotes beginning with system #1 to begin replacing. Customer doesn’t want to invest anymore into system.

Tech returned to replace TXV in air handler under full warranty. Pressure tested with nitrogen and pulled vacuum down to 370 microns. Tech added 8lbs 5oz of R410A to get charge correct. System is back operational at this time.

Upon arrival tech was informed of issues found during home inspection. Corrections made are, upstairs line set had a small piece of insulation added to it. Downstairs return line had insulation fall down from broken strap, pulled insulation up and replaced panduit. Downstairs branch line was sagging, added hanger strap to raise back up. Coil was producing excessive condensation due to clogged drain line, cut line and cleared with nitrogen and added 3/4” union for future cleaning.
