I arrived to client unit not heating properly. The google nest thermostat displayed a aux wire issue. I first diagnosed a short in the wire. I explained this to our client and began the process of locating the short. I found multiple wires had been compromised from the air handler to the outdoor unit. I explained my finding to our client and he understands that if more wires get compromised that new thermostat wire would need to be ran to the outdoor unit. Once I completed wiring up the unit. I put the unit to heat and ensured both indoor and outdoor units were heating properly. I should our client my concerns for the high start amps on the outdoor unit and burnt contactor but he did not want to address them today. He also declined signing up for routine maintenance as he plans to move. The unit is heating properly on departure.

Scope of Work Current System Condition: • The existing air handler at the customer’s house is in poor condition. • The evaporator coil is heavily contaminated with dirt and debris. • The control wiring is not functional, does not meet code requirements, and requires replacement.

Outside Unit Repairs Repairs to extend the lifespan of the outside unit: 1. Replace the contactor. 2. Install a hard start kit to reduce startup amperage on the condenser. 3. Perform a chemical wash on the condenser unit and remove all trash and debris. 4. Install Armaflex insulation on the copper refrigerant lines. 5. Install low-voltage conduit to protect control wires entering the condenser unit. Indoor Blower Motor • The blower motor was recently replaced and is in good condition. • The replacement air

System wasn’t making any excessive noise at the time of service. Customer stated that on Thursday night is when it happen. Also, it was stated that the system was still heating when noise was happening. This can indicate that it was the defrost cycle and that it switched to heating strips to allow the system to still heat. I believe it she heard the defrost cycle while temperatures were extremely low. I asked the customer to record it the next time it happened so we could have a noise reference. Checked the amps, capacitor, and starting amps.

Arrived to the customers house. The main electrical panel breaker was turned off completely. Jose and I went inside the house to verify the unit to see why the unit was turned off. Open up the inside unit looked over to make sure there was no grounding on the electrical side. Reset the main breaker at the panel. Turn on power to the inside unit unique came on and ran for a short time than the outside breaker tripped again. Took the logical panel door off the main power. Found the wires going into the main breaker was loose. Took over five turns to tighten down the wire in the breaker. Reset the breaker in the main panel unit came on. Forced unit to go in full max operation with the heat kit on as well to verify the system is going to maintain running. And the breaker is going to hold up. meter on the system was pulling over 49 A of heat strips. Verify the heat pump outside if running in perfect conditions. Opened the outside, cover and verified all the main variable speed is w

2021 Goodman 4 ton 2 stage gas furnace with 2 stage cooling. Preformed fall system maintenance 2 stage gas furnace. Unit is operating with manufacturer specifications. Found a lack of air flow across evaporator coil temperatures at furnace readings 170 + degrees just be for coil and after coil reading 99 to 106 at it highest temperature level. Recommend pull and clean on evaporator coil. Check all safety components and they are all operating as they should. Unit is fully operational upon departure. Filter is slightly dirt recommend replacing. Filter size is 20x25x4”

Performed single system heating maintenance. Checked amps, capacitor, filter, electrical, safeties, drains, and cleanliness. System is heating to manufacture specifications. Customer mentioned the compressor is loud. I had the customer turn on cool and took a quick look. With the current weather conditions, I can only tell so much. I spoke with the customer and told him I would like to recheck it when it’s hotter outside. The compressor is amping kinda low and the system is being over supplied power to the condenser and furnace. The outdoor unit is receiving 251v and the indoor is receiving 124v. This can be an electrical supply issue from the city. Over supplying power to the outdoor unit by 11v and can cause the compressor to be louder than usual. Recommendations 1. Customer is having to change the filter more often than projected and the ducts are beginning to build dust again. I recommend adding a ApcoX to help with dust content and potentially extend the life of the filter. 2

Outdoor system was not making a noise when I arrived. After examining the unit, I noticed ice all over he weather guard and in the bottom of the heat pump. I did not notice any scraping marks. I suspect the customer was hearing one of three things: ice falling into the fan blade, ice build up on the fan blade, or defrost mode.

Arrived at home for gas leaking from flex gas line into furnace. Was previously diagnosed by gas company. Found gas line to be extended too tight and leak was present at the very tight bend into the furnace. Replaced gas flex line and extended black gas pipe to allow more smooth bends in line. Once replaced I tested all connections points with uv bubbles and ensured furnace was running properly.

Arrived at our client home for furnace not heating properly. Client read error code to have a faulty pressure switch. I confirmed the pressure switch was the issue. The office agreed to waive the dispatch fee with today’s repair. Once the pressure switch was replaced we ran the unit in heat. It ran for more than 20 mins without any errors or issues. I discussed maintenance with our client and sent him an estimate for a maintenance plan.
