McKinney, TX – AC Repair & Heating Service

Performed 3 system heating maintenance. Checked amps, capacitors, filters, cleanliness, drains, and safeties. Systems are heating to manufacture specifications. Recommendations 1. I suggest upgrading filters due to the huge gaps in the filter box. This is the help maintain a clean system and reduce the possibility of having to clean the blowers and ducts sooner. 2. To help maintain a clean system I suggest we add u/v lights.

Returned to home for sensors not properly commanding unit to turn on and run. Client explained he shut off unit from furnace. Replaced batteries. And reconnected sensors to the thermostat. After multiple attempts on Saturday he was finally able to link the sensors to the thermostat. I explained that I was planning on doing the same procedure. But that the intermittent issues was most likely a precursor to complete failure. They agreed to replace the sensors under warranty. We also discussed airflow issues throughout the home and our client want to move forward with scheduling a complete air balance per unit for the entire home.

Performed system maintenance on a Perform system maintenance on 2015 Lennox Gas system. Everything running as it should upon arrival and departure spoke with homeowner about allergies in the home he said both. Him and his wife have an issue with them. Recommended UV air filtration system. We had a discussion about the UV light works inside the system to kill any Bacteria and allergens brought in from outside the home. Checked amp draw on indoor unit and outdoor unit both within manufacturer specs outdoor capacitor was just recently changed In 2024

I arrived at our clients home for one of the units not heating properly. Our client made an adjustment to the thermostat and through the night the unit failed to heat the desired space. The client had reset the temperature sensors for the thermostat and the unit was currently heating properly with no errors or issues present. Our client and I also discussed concerns to achieve a desired humidity level in the home. The current unit has a steam humidifier with a T in line with the supply plenum that should be rerouted. We also discussed indoor air quality in the home and duct cleaning to help remove the dirty sock syndrome they have in the home also. I have created an estimate for maintenance plan And will also create an estimate for air balancing. They would like to hold off on the duct cleaning for now.

Performed courtesy check up on front 4 ton package unit on roof rooftop unit is operating upon arrival and departure. Noticed unit pulling a high amount of amps at disconnect. Reason being the unit itself is working twice as hard to push and pull. It’s normal operating components under stress due to bacteria and dust buildup accumulated inside the evaporator coil, blower motor and blower motor housing, as well as condensing coil. Recommending a level two evaporator chemical clean as well as a level two condenser chemical, clean as Trane has a sophisticated one of a kind Coil fin system layout that helps your unit, transfer heat and or cooling faster and more efficiently. Unfortunately, with that one of a kind system, it tends to collect more debris in the tighter hard to reach places. Also found condensing fan motor & indoor Blower motor under the 6% manufacturer recommends replacing. Blower motor capacitor rated for 20mfd, reading at 18.09mfd. Condenser fan motor rated for 7.5mfd.

I arrived to replace outdoor sensor on the variable speed heat pump. Once replaced I proceeded to use the thermostat and test the unit in heat mode using the outdoor unit only. I let the unit run for 20 min and asked our client to listen for any repeat rattling noise from inside the master bedroom. Our client could not hear the noise at all while the unit was running. We discussed running emergency heat when temperatures are below freezing. And our client was happy noise was no longer being heard in the home. System running properly on departure

Upon arrival, condensing unit slightly frozen, with debris buildup around condensing coil, not allowing proper airflow across coil, causing to compressor and motor to operate and continuously work hard harder. Down capacitor on outdoor unit below manufacturer spec for change out recommend replacing with a turbo 200 capacitor. Compressor and fan motor struggling to start. Recommend a hard start kit to help jumpstart the initial start of the unit. Upon visual inspection of indoor unit found 20 x 20 x 1” filter hasn’t been replaced since 8/24/24. It 1 inch filter should be replaced every month debris buildup on filter after removing filter filter. Unit started to heat a little bit check evaporator coil noticed half the coil is clogged full of debris not allowing unit to heat or cool properly recommend in place level two chemical clean for evaporator coil. Temperature is too low to determine Freon levels needing to clean system first with level two coil cleanings inside and out, replace

Zone damper for the upstairs is stuck open causing the upstairs to become overheated.

Performed single system heating maintenance on a 2013 zoned furnace. Checked amps, filter, electrical,drains, cleanliness, and safeties. System is heating to manufacture specifications. Recommendations 1. Upstairs is getting over heated due to a failed zone damper not closing when voltage is applied. 2. The system currently does not have a water safety switch. Without this switch, there is a higher chance of water damage happening when a clog occurs.

Installed 2 stage gas valve and LP kit. Tested the unit and it is now heating.
