McKinney, TX – AC Repair & Heating Service

Customer stated that the unit (#2), wasn’t working, that it was completely off that the thermostat was blank at a times,,, but it was doing this just on cooling mode. Started diagnostic at the thermostat, set it to cool, proceeded to inspect the indoor unit, verified proper voltage power signal to cool, noticed notification at the thermostat saying waiting for equipment,,, proceeded to inspect the outdoor unit, found a bad 2 pole contactor, brought this up to customer’s attention, decided to replace the part today, after replacement we verified proper system operation, found no more issues at this time.

Performed a 1 system spring maintenance ( gas). Tasks performed. 1. Visually inspected condenser coil for debris/ dirty,,,recommended a surge protector this would protect the outdoor unit from over current to. 2. Inspected condenser fan motor. 3. Inspected condenser fan blades. 4. Inspected/ cleaned wiring connections. 5. Tested compressor/ condenser fan motor capacitor,,,recommended a hard start kit this extends the life on the compressor and releases stress at start up. 6. Checked refrigerant pressures. 7. Checked compressor amp draw. 8. Checked condenser fan motor amp draw. 9. Inspected / replaced return filter. 10. Inspected return plenum for debris/ dirty. 11. Inspected evaporator coil. 12. Inspected blower motor/ blower wheel,,,both are dusty highly recommended a blower cleaning,, this prevent buildup on the blower wheel then unbalance. 13. Checked blower amp draw. 14. Measured temperature differential . 15. Inspected drain lines. 16. Washed condenser unit. Unit is cooling prope

I found the outdoor unit tripped on a hard lock out. The defrost board did not give any information beyond that. I hooked up my gauges and reset the defrost board. The compressor started with no issues pulling 8.5 amps on start up. I watched the refrigerant pressures and it appears the pressures are low. I covered the unit to simulate a harder day and the subcool was at a 3.1 at the highest and the super heat was 23.3. I offered pricing to add refrigerant and the customer declined. I spoke with the homeowner about part availability and the possibility of finding 410a replacement parts. The system could need more than 3 pounds and this would be determined when adding.

Arrived on site, customer stated unit was not cooling while running. Upon initial inspection, it was noticed that two filters were being used a 4 inch on the unit and 1 inch filters on the ceiling. Proceeding to the outdoor unit, it was noticed that the coil on the condenser was pretty dirty. Upon further testing, it was found that the unit had exceeded the locked rotor amps. The compressor had gone into lockout safety not allowing the outdoor unit to turn on. We reset the safety and tested the outdoor unit. We found the compressor to have exceedingly high start amps over the manufacture limit. We showed our findings to Paul and we discussed options to bring start amps into normal range and also maintain the overall performance of the system. Our client elected to have the maintenance preformed today and we flushed and cleaned the drain line as well as washed the outdoor unit. Our client also elected to install a hardstart kit to help keep the compressor amps within manufacture specif

Arrived to unit not cooling and continuous blown fuse inside the furnace. Upon arrival David explained he had replaced the thermostat and 3 different fuses and the unit would not come on in cooling mode. I immediately proceeded outside and found a failed contactor. I further tested the unit and found the capacitor to have early signs of failure. I showed my findings to David and he elected to replaced both components today. Once replaced I further tested the unit to ensure it was cooling properly. I found the compressor start amps to exceed manufacture specifications. I also found the indoor blower wheel to have significant dust accumulated on it from candles and dust in the home. The indoor blower motor was reading 9.36 and is max limit is 10. I discussed with David how the dust on the blower motor is contributing to significant wear and strain on the system. I will send over an estimate for blower cleaning and a hard start kit to help the compressor. The system is cooling on depar

Arrived at clients home for ongoing issue regarding heat pump heat vs gas emergency heat. Our client confirmed that both zone thermostats are set to either heat or cooling only and not on auto. Our client said that the indoor temperature was reading below desired set point and they had to manually set the thermostat to emergency heat to come on and heat the home. I proceeded into the attic and found the air filter had not been cleaned from our last visit in February. Our clients are currently doing different home renovations projects which are contributing to high amount of construct in the home and being caught by the filter. We discussed how the filter is set to notify after a set period of time and not by the actual cleanliness/dirtiness of the filter. Today, as a courtesy, I dusted off the filter and sent a video to our client on what other parts of the filter still need to be cleaned. I did not preform a full filter cleaning and our client was deliberate about not wanting to p

Performed a 2 systems spring maintenance ( gas). Tasks performed. 1. Visually inspected condenser coil for debris/ dirty. 2. Inspected condenser fan motors. 3. Inspected condenser fan blades. 4. Inspected/ cleaned wiring connections. 5. Tested compressor/ condenser fan motor capacitors. 6. Checked refrigerant pressures. 7. Checked compressors amp draw. 8. Checked condenser fan motors amp draw. 9. Inspected / replaced return filter. 10. Inspected return plenums for debris/ dirty. 11. Inspected evaporator coils. 12. Inspected blower motor/ blower wheels. 13. Checked blowers amp draw. 14. Measured temperature differential . 15. Inspected drain lines. 16. Washed condenser units. Found no issues/ concerns units are working properly at this time.

The system is not cooling at factory specs. There is a leak on the coil, and it needs to be replaced

Replacement of failed humidifier control board Clearing drain line to ensure proper drainage on primary drain line for master bedroom unit and humidifier. I returned to our clients home today to complete Previously quoted repairs. Upon arrival Karl informed me that water had been leaking from the upstairs unit drain pan. We proceeded into the attic and found the primary drain line completely disconnected from the primary drain line outlet. It appeared to not have any pvc glue or adhesive from the time of install. The line was short and did not make a secure connection. I added a small piece and coupling as a courtesy, to better secure the drain line. Karl wanted to move forward with his remediation company. I then went to replace the steam humidifier control board. Once replaced Karl and I turned the unit to heat and ensured the humidifier was working properly and creating steam. At the same time I flushed and cleared the primary drain line with nitrogen to help prevent future clo

Customer system was showing a constant delay at the thermostat. I went into the attic and jumped the unit in to cooling. This caused the low voltage fuse to pop. I proceeded to go outside and find a shorted contactor. Also, I observed that the system has some wires burning, the compressor sounds awful on start up, and the condenser fins has debris in it. I provided pricing for all repairs. CONTACTOR * 1 POLE 25 - 30 AMP 24V CONTACTORS ARE SWITCHES THAT USE HIGH VOLTAGE TO HELP COMPONENTS IN YOUR UNIT. SINCE THEY ARE IN CONSTANT USE, THEY DO NEED TO BE REPLACED OCCASIONALLY.
