Heating and Air Conditioning Services in McKinney, TX

Upon arrival, I discovered that the compressor was not turning on and the condenser fan motor running backwards. After further assessment, I found the capacitor to be mostly dead on the fan and compressor terminals. I wired a new capacitor in for testing purposes. The system came on and began cooling. I performed evaluation of the entire systems operation and discovered that the outdoor unit needed a rinsing, as well. The system is cooling upon departure.

No cool on single system. When thermostat was set to cool, indoor blower was running. Went outside and condenser was not running. Checked capacitor and it was dead. Contactor is original on unit, recommended replacing it. Customer approved repair to replace capacitor with five year warranty, and contactor. Tested system after repairs were made. Measured amp draw on compressor and fan motor. System is cooling at this time.

No cool on upstairs system. Indoor blower was running. Customer said breaker tripped yesterday, and when he reset it heard a loud pop. Went outside to condenser and found that compressor plug had been blown out of it. Compressor needs to be replaced along with power plug going into it.

Upon arrival, I found that indoor unit was running properly, but air filter needed to be replaced. I removed air filter from system and homeowners will replace later today. I tested drain line drain line is not clogged. I found that start capacitor at outdoor unit unit was completely dead. And outdoor unit was in need of a light cleaning. I replaced a 45/5 start capacitor and performed a light condenser cleaning. Tested system, system is running properly at this time.

No cool on single system. Customer stated that system would not keep up with the set temperture when it got to the hottest part of the day. Checked temperature drop across system and only getting 13° difference. Checked refrigerant pressures and it was low. Performed electronic leak search and found leak in evaporator coil where it can not be repaired. AC will need to be replaced. Customer approved adding 2 lbs of refrigerant to help get them by until it gets replaced. They understand there is a leak and there is no warranty on the refrigerant. Jesse is coming out later today to give them estimate on replacement.

Customer has humidity issues in the house and is trying to narrow it down to what could be causing it. House was built in 1901 but was remodeled about 6 years ago. New windows, new AC system, new blown in insulation. Home does have roof leak that is getting fixed in the next few days. Also had leak under kitchen sink, he will be fixing drywall around sink area to make sure that is completely dry. After going through the AC system, refrigerant pressures and temperture split are within acceptable range. There are a couple dehumidifiers running in the house right now to help with humidity but it is also adding heat into the home. Sending customer estimate for whole home dehumidifier that would be attached to the hvac system in the attic. 5 supply grills have biological growth in and around them. Recommend having ductwork cleaned out and sanitized. There is a bit of growth on the evaporator coil, sent estimate to do foam cleaning on it. Duct cleaning lvl 3 includes the coil cleaning in the

Removed old damper motor for upstairs zone. Removed actually damper from plenum and flipped it over to have it pointing the correct direction. Sealed around damper and re-insulated it. Installed new damper motor. Tested operation with damper closed and open. System is cooling at this time.

Arrive to replace bypass damper. Customer said it was blowing a lot of air downstairs. After inspecting the unit, found that upstairs damper was not opening when thermostat was calling for coil, this was forcing air downstairs instead. Bypass damper is working correctly. Zone damper motor for upstairs needs to be replaced. Also, damper is facing wrong direction which is why the damper motor failed. Need to installed damper correct direction. Left damper open that way it will still blow air upstairs until we can come back.

I found that pigtail connection inside junction box had melted. I removed pigtail and wired existing wire straight to furnace for temporary use. Will need to return return to install install new light switch box. Emailed estimate to Mike. System is properly running at this time.

Customer had concerns about uneven cooling in the house. Checked supply temperture and it was 52°. Went into attic and checked ductwork. Found 1 duct completely disconnected at the Y going into the living room. The other duct going into the living room had over a foot of insulation missing. Found another duct run missing over a foot of insulation as well. Notice a ton of air leaking from plenum connection into the attic, the tape had almost come off all the way. Insulation in attic is below the rafters, this makes it easy for hot attic air temps to seep into the living space. Customer approved repairs to reattaching the ductwork and getting flex fully covered with the insulation. Also sealing around the plenum connection in the attic with tape and air mastic.

Customer stated that system was not keeping up with thermostat during the middle of the day. Went to check temperature split and found that furnace door was left off during our last visit. This was bringing in attic air to the system. No charge. System is cooling at this time.

Three system AC maintenance. Customer replaces own filters, downstairs filter needs to be replaced. Checked operation of drain lines, treated them with drain solution. Measured amp draw on blower motors. Check temperature drop across coils, they are all cooling within acceptable range. Checked capacitors and contactors, they are in good condition. Clean condenser coils using water. Systems are cooling at this time. Did a hard reset on downstairs den system, error codes did not come back.

Customer has a failing 40/5 capacitor. This part is needed to start the comoressor and the fan motor. When the charge gets out of the manufacturer specified range, it can begin to damage the compressor and fan motor until it won’t start anymore. The compressor is starting with a high amp load and will likely damage the windings. Hard start kits are used to lower high start amps. Replaced Start Capacitor and installed hard start kit. Tested drain line. Drains were clear at this time. Homeowner is aware the condenser needs a chemical cleaning so the system can run efficiently and bring down the humidity in the house. System is running at this time.

On arrival customer stated that yesterday the system did not seem to be cooling and temperature got up to 76°. He turned it off earlier this morning. Set thermostat to cool and checked operation. Measured temperature drop across system, getting 74° in and 54° out. Poured water down drain line to verify it was clear. Filter was in good condition and nothing was blocking airflow. Checked refrigerant pressures. Subcooling is right where it needs to be and pressures are within acceptable range. Condenser coil is clean and capacitor is good. Unable to find any issues with system. Temperature downstairs went from 74° on arrival down to 70° while checking over system. Customer will let us know if something happens again. System is cooling at this time.

1 system AC maintenance. Set thermostat to cooling test mode. Customer replaces his own filter. Measured amp draw on blower motor. Tested drain operation and treated it with drain solution. System has safety float switch installed. Checked temperature drop across coil, getting 19° difference. Measured amp draw on compressor and condenser fan motor. System does not have capacitor or contactor. Cleaned condenser coil using water. Replaced suction temperature sensor under parts and labor warranty. Fault code on thermostat cleared and system is cooling at this time.

Upon arrival I found that upstairs system is only cooling the air down 11 degrees. The return is pulling in 68° and the supply is putting out 57°. I also found for the upstairs system at the condenser the start capacitor is weak reading 31 out of 35. I recommend replacing start capacitor at upstairs condenser. I also found that for the downstairs system at the condenser the start capacitor is also very low. Reading six out of 70. I also recommend light condenser cleanings on both systems. But especially for the upstairs system so that I can accurately check refrigerant pressures. Replaced both start capacitors on both condensers and performed light condenser cleaning on both condensers. Checked pressures after cleaning and still no improvement on the temperatures upstairs. Still just 11 to 13° split. I performed electronic leak search on both evaporator coil and condenser for upstairs system. Electronic leak detector could not detect a leak.

Performed two system maintenance. Homeowner complained about upstairs system not keeping up. During the maintenance I found that upstairs system was only cooling it 13 degrees. The system was pulling in 73° and putting out 60. On upstairs system I also found that one of the air filters was extremely dirty. On upstairs system I also found a low run capacitor on the blower. I also found a low start capacitor on the condenser. On the downstairs system, I found that the start capacitor on the condenser was low as well. I brought this to the homeowners attention that if she doesn’t want to replace these capacitors now she should definitely replace capacitors come next spring. After performing the condenser cleaning, I checked temperatures on upstairs system again and found that the system was pulling in 77° air and putting out 57° air so I believe between the dirty air filter and the condenser getting a light cleaning. This should improve the air for the upstairs. Both systems are running p

No cool on gym system. Thermostat was set to cool but system was not running. Found that primary drain line was clogged up, causing the float switch to turn the unit off. Cut drain line and cleared it using nitrogen. Glued drain line back together and verified it was draining. Poured water down line and watch all water drain out properly. Checked temperature drop across system, 79° in and 60° out. Filter is dirty, should be replaced soon. System is cooling at this time. Filter sizes: 2- 20x25x4”

Upon arrival I found that condenser fan motor was running and compressor was not. I found that start capacitor was low reading 45 out of 60. I informed homeowner that I would need to replace start capacitor in order to get compressor to run so that I can further diagnose the issue. I replaced the start capacitor with a 60/7.5. Since compressor was grounded, I removed new capacitor and did not charge. Homeowner for this capacitor. Replaced old capacitor back into outdoor unit.I restored power to condenser and then found that compressor was grounded. I would recommend full system replacement due to the age and the type of refrigerant. The age of the system is 20 years old. This system is a R 22 refrigerant.

I replaced warranty blower motor and control board. Tested system and system is running properly at this time. Will need to return to warranty (2) 824 thermostats.

Upon arrival I found that outdoor unit was coming on a short cycling turning off after about 20 seconds. I found that blower motor inside furnace was not coming on. Upon further investigation, I found that control board was not giving the correct voltage to the blower motor. Blower motor had burnt up due to insufficient voltage from control board. Will need to order new control board and blower motor under warranty. Homeowner also wants to warranty the two thermostats. Homeowner would like thermostats, control board and blower motor to be done on same day.

performed maintenance

Upon arrival, I found the outdoor fan motor running. It had been replaced. I discovered that the compressor capacitor had ruptured. I presented options for replacement. The client opted to install a Turbo200x. I tested the system afterwards to ensure system is cooling properly. System is cooling upon departure.

Arrived on site replaced filter that was not changed during the maintenance due to a mislabeled filter.
