McKinney, TX – AC Repair & Heating Services

I performed a cooling maintenance on a 2017 zoned heat pump system. I checked amps, capacitors, filter, electrical, cleanliness, drains, safeties, and rinsed the outdoor unit. During my thorough evaluation, I determined that the system has a couple issues. The primary drain line is having a slow drain issue, the outdoor capacitor failed testing due to out of range charge, the compressor is starting with a high amp load, and the outdoor unit is in need of a deep cleaning due to stubborn debris and oxidation. I made the customer aware and presented options to address these issues at the time of service.

I performed a single cooling maintenance on a 2021 zoned communicating Amana heat pump. During my thorough evaluation, I did not discover any mechanical issues that needing addressing. However, I did discover that the outdoor condenser coils is damaged and needs a chemical bath to remove oxidation. I provided an option to address these two areas of concern during the time of service. Customer elected to perform the coil combing and algae stick. Customer would like to schedule next week and time does not matter.

2011 furnace and condenser carrier outdoorHomeowner complained system was not keeping up the way it used to. Turned unit onto cooling and checked refrigerant pressures. Pressures were very low indicating there is a leak in the system. I could not see any obvious leak in the outdoor coil or service valves meaning it is likely in the attic evaporator coil. Advised homeowner we would need to charge for a leak search in the evaporator coil to confirm but it is more than likely that this is where the leak is. Found capacitor dated from 2011 and is liable to fail at anytime. Outdoor condenser coil is very dirty and could have contributed to the leak. Notice ductwork in attic was missing insulation. Also found gas leak in downstairs unit’s furnace. Shut off gas and informed homeowner. Blower wheel is extremely dirty and in need of chemical cleaning. Advised homeowner that this coil is not under warranty and 410a equipment is being phased out. This makes the coils difficult to obtain if we can

Performed 4 system cooling maintenance on gas equipment. Checked amps, capacitors, filters, drains, cleanliness, and safeties. Left side downstairs unit needs a capacitor replacement due to it beginning to fail. This part is responsible for starting the outdoor unit. Right side upstairs has an emergency pan that is rusting through and will likely cause water damage. Highly advise replacement before damage occurs. Right side downstairs unit needs a return duct to be supported. This causes an air restriction and will result in equipment damage. All of the units need blower wheel cleaning to remove strain on the motors. This can lead to motor damage. I emailed all of the estimates over for review and all systems are cooling upon departure.

HVAC Comfort & Performance Evaluation Summary Customer Concern: The primary concern is the master bedroom being extremely hot, humid, and uncomfortable compared to the rest of the home. The customer explained that this room does not maintain proper comfort levels, especially during warmer parts of the day. Home Information: • Home was built in 2021 • Existing HVAC system has only had minor repairs performed • No full system performance evaluation or complete maintenance inspection has been completed on the system Findings During Initial Evaluation: 1. Poor Airflow to Master Bedroom After inspecting the supply register in the master bedroom and physically checking airflow at the vent, it was determined that airflow is extremely weak and insufficient for the size of the room. The amount of conditioned air being delivered is not strong enough to properly cool and dehumidify the master bedroom, which is a major contributor to the discomfort. This room requires stronger airflow and p

Upon arrival, I discovered the system to be empty of R22. The system is from 1990. This is a Frankenunit. The cooling and heating are completely split, but the ducts are set up to allow heating and cooling to be supplied. The cooling downstairs is shut off by a manual damper. The unit does not have zoning and has 2 thermostats. Review video to see what I mean by completely split.

Replaced suction line temperature sensor. Insured unit was cooling properly upon departure.

1. Visually inspected condenser coil for leaks and abnormalities. 2. Inspected condenser fan motor, blades and bearings. 3. Inspected, cleaned, and, tightened wiring connections. 4. Measured capacitance of compressor/fan motor capacitor. 5. Inspected and measured resistance of contactor 6. Measured compressor current draw. 7. Measured condenser fan motor amp draw. 8. Inspected and replaced return filter. 9. Inspected return plenum for dust or debris. 10. Inspected evaporator coil for cleanliness and oxidation. 11. Inspected blower motor/ blower wheel for dust and debris 12. Measured blower motor current draw. 13. Measured temperature differential from supply to return. 20 degrees measured. 14. Tested drain lines for proper drainage and treated to prevent blockages. 15. Rinsed condenser with water to promote heat exchange and reduce stress on system by removing dust and debris. Starting to see m Small amount of dust in return plenum and ducts but not so much that I would say a duct cl

Found large amount of dust and debris in the return Plenum and ducts. I advised duct cleaning to remove dust

Upon completion of my thorough evaluation I found that the outdoor coil could benefit from having a deep cleaning done on it. By having it cleaned you can help the unit run at its peak performance and efficiency. Temperature sensor was the wrong sensor will have to come back.
