Upon arrival, I hooked up my gauges to check resting pressures. I proceed to use my leak detector to check the indoor and outdoor coils. The leak detector did not detect any refrigerant leaks. I turned the unit on and checked running pressures. I took a temperature split and examined the ducts. I located a bypass duct that was set to .7wc. I turned it down to .4wc. The system is cooling inside of manufacture specifications. Customer and I spoke about surge protection and air cleaning devices. I provided pricing to install them to the system to help with allergies and protect the electrical from power fluctuation.
I arrived out our clients home for a single system with 2 zone unit not cooling properly. James first showed me the locations to booth thermostats and the attic access. I then proceeded outside to the outdoor equipment. I immediately noticed the suction line to be frozen over. I shut the unit off at the outdoor disconnect and tested the capacitor and contactor. The capacitor was reading lower than previously measured during the august 4th maintenance visit. I then went into the attic and found the evaporator coil completely frozen. I shared my finding with James and we discussed either thawing out the coil by turning on the furnace or shutting off the compressor and allowing the ice to naturally melt. We agreed that allowing the ice to melt naturally was the best option to not cause any potential damage to the evaporator coil. James elected to replace the capacitor today and we are scheduled to return tomorrow to preform a leak search on the coil. We will also provide a filter as a cou
Arrived on site found blower motor not running when calling for cooling. Evap coil was frozen. Tested g and found 24v. 120 measured to blower when calling. Powered unit off and turned it back on again. Blower cam on without issue. Switched unit to heating mode in order to Melt the ice. Unit operated in heating mode without issue for 5 mins. Switched unit to cooling once ice had fully melted. Blower and condenser came on without issue and continued to run for 40+mins. Measured refrigerant pressures and found them to be within manufacturer specifications. Advised homeowner I could not reproduce the issue at this time and the issue could either be with the control board or a power surge issue. Offered surge protector to possibly prevent this from happening again. Homeowner declined at this time. Unit in good working order upon departure.
Preformed dryer vent cleaning. Upon arrival client stated the dryer was giving an error code of 80percent blockage. I inspected the dryer vent and saw a good amount of lint build up. I disconnected the dryer vent hose and began clear the vent. A substantial amount of lint build up was cleared from the vent. I proceeded to the attic were i disconnected the vent piped to the roof was and cleared any lint build up further up in the vent stack. After completing the dryer vent cleaning I inspected for cleanliness all around.
Arrived on site, heavy rain present at time of service. He began inspection at the air handler. Tested stage one and stage two heat. Both stages were operating normally and putting out correspondingly warm air. Extensively tested 20kw heat strips and found them all to be working well. Tested float switch and drain line and found them to be working as intended. Measured blower motor amps, no concerns at this time. Found some bacterial growth around the blower housing and door insulation. Brought is finding to the attention of the homeowner and provided estimate to his email. Unable to proceed further at this time, informed customer I will need to come back later this afternoon once the rain has let up to finish testing on the outdoor unit.
Returned to add a supply and return vent in the attic due it being foamed and to help out with the humidity. Did seal the added ductwork and hang properly. Customer paid the remaining balance with a credit card
Demand call for system having some kind of biological growth on the supply side and some of the ductwork not being properly sealed. Upon arrival the customer took me to the attic to show me the areas of concern. Some of the ducts attached to the supply boxes and mixing boxes had minor air leaks causing some growth around the connections. I was able to remove the growth and reseal the ductwork, I informed the customer that I can’t guarantee the growth won’t come back but properly sealing the ductwork and adding a return and supply vent in the attic to help with the humidity of the foamed attic will definitely help prevent it from coming back. Customer does have an air scrubber and has replaced the bulb in it already and he will like to add the vents in the attic to maximize the defense against the growth. Customer signed the estimate and paid a $100 deposit that will go towards the total due when the work is completed. I informed him that the office will call him tomorrow morning to

Homeowner elected to let it be for now and keep an eye on it.
Preformed 1 system cooling maintenance. Met homeowner outside, he had no concerns at the time of arrival. Proceeded inside garage for attic access, tested all electrical components inside all tested within manufacture specifications. Changed filter 20x25x1. I noticed the client does not have a primary safety float switch and blow out valve. Left estimates for each. Client did not want to go forward with at this time. Treated primary drain line with total c. Proceeded outside to check all electrical components, start and run amps of the fan and compressor motor. All electrical components tested within manufacture specifications. Run and start amps tested within manufacture specifications. Rinsed out door coils Temp drop across the inside coils is 20 degrees 74 coming in 54 coming out. Unit was cooling upon departure.
Performed work for replacing blower motor under warranty. Motor started up without issue. Tested refrigerant pressures and found them to be within range. Rinsed condenser as a courtesy to ensure proper heat exchange. Unit in good working order upon departure.
Arrived on Site, powered unit on test. Unit would shut off very quickly after starting. I measured pressures, and found high superheat and low suction pressure. Tested contactor and capacitor both were testing within range. Start amps and run amps tested within range. Proceeding to the furnace I found the blower motor was not running. Tested power coming into the motor and found power making in to the motor. Measured resistance on the motor and found no resistance. Informed homeowner that we would need to order the motor first thing in the morning as the supply houses are closed right now and we would contact them tomorrow morning with more information as to when we could have this motor installed for them. Collected $200 deposit in order to get this motor on it way and process the warranty paperwork. Condenser breaker left off in order to avoid damage to the unit.
Customer stated that unit stop producing cold air yesterday or the day before, so they shut off the unit. Upon arrival I checked standing pressure on unit and it appeared to be low. Tested capacitor and contactor both were testing within range. Proceding to the attic unit, I found the drain line to be draining sufficiently and the float switch not triggered. Upon inspecting further I noticed I could hear hissing coming from the evaporator. I then conducted a leak test and didn’t not find any leaks around the TXV or connections with a bubble test. On my leak detector I was immediately getting hits of refrigerant around the bottom left side of coil. Discussed with customer that the coil was in stock but our install team would not be available until Saturday morning. Offered window unit to hold them over until we could come out to repair the leak and home owner accepted. 26907505 Order number Trane McKinney in stock

I returned to our clients home to preform a quality control check on the evaporator coil. I measured the temperature drop inside the attic unit and also checked refrigerant pressures. Everything passed and is running perfectly. I also took time to talk with Tom and discussed how we can improve in our services. We will update and send a final invoice and he would like to explore financing options for work that was preformed. The unit is cooling properly on departure.
