1. Visually inspected condenser coil for debris/ dirty. 2. Inspected condenser fan motor. 3. Inspected condenser fan blades. 4. Inspected/ cleaned wiring connections. 5. Tested for gas leaks 6. Tested functionality and cleaned flame sensor 7. Tested functionality and cleaned pressure switches and ports 8. Inspected / replaced return filter. 9. Inspected return plenum for debris/ dirty. 10. Inspected evaporator coil. 11. Tested functionality and visually inspected surface igniter 12. Checked blower amp draw. 13. Measured temperature differential from supply to return. 20 degrees measured. 14.Drain line tested with gallon of water for clogs and to push anything trying to solidify out Found outdoor condenser blanketed in debris and dust. This causes undue stress on the compressor and all connected components. I would highly recommend having the coils cleaned in order to keep this unit alive as long as possible. I also noticed there’s no float switch on this unit. This can cause water t

Arrived on site for no heat. Customer was having issue operations the thermostat. She stated that thermostat would need to be set again and again after going to sleep. Performed check over entirety of system and found no issues that would cause system to not run as intended. Noticed very large blanket of dust and debris on outside condenser coil. This will cause undue stress on the system and lead it into an early grave If it is allowed to continue like this. Provided options for getting this issue addressed including chemically cleaning indoor and outdoor coils, and blower wheel as well as a duct cleaning. This will improve air quality inside and prolong life of system. I also noticed there was no float switch on the indoor unit. This can cause water to come through the ceiling if the primary drain line is blocked. Discussed thermostat programming and how to set a manual hold with the homeowner. Unit in good working order upon departure.

Upon arrival, I found the thermostat blank. I went into the attic and discovered no power in the furnace. I proceeded to the main electrical panel and located a tripped breaker. I reset it and found that the switch in the attic was off. I turned it on and got power back in the unit. Customer needs to replace 16x25x4 filter. I cycled the heating 2 times and ensured it was going to work and satisfy the temperature demand. Customer is unaware of when the issue happened. From what I can deduce, is that the flue likely got blocked by ice and tripped the system. System is heating inside of manufacture specifications upon departure.

Preformed duct cleaning estimate. Showed client before and after pictures and walked him through the process for each system. Client would like to speak to his wife about the estimates.

I performed a single heating maintenance on a 2017 zoned gas system. I checked amps, filter, electrical, cleanliness, zoning, and safeties. Before I got started, the customer mentioned that it seems like the downstairs is not heating. I investigated this concern to the best of my ability. I verified that the zoning is working properly for the upstairs and downstairs. When I was running the system with both zones on in heating, I discovered that the system is producing extremely hot air. I checked the ducts for appropriate design. I discovered that the system does not have enough return air. It currently only has approximately a 18in duct. The bypass is opening with both zones running. The unit is full of dust and debris. This is likely playing a role in the unit tripping on a thermal cut out. I advise a complete cleaning be done on the system at the least. I will get with my supervisor about a possible work around for the poor duct design.

I performed 2 heating maintenances on 2015 90% gas systems. I checked amps, filters, electrical, drains, cleanliness, and safeties. During my evaluation, I discovered that the system for the main part of the house has a failing capacitor on the inducer motor. This will cause the unit to stop heating when it fully goes out. I noticed that the equipment does not have surge protection, and I advise performing a drain treatment to ensure the drains are good because 90% gas systems produce water when heating.

Upon arrival, I discovered that the door was off the unit. These door go on a specific way. I installed the door back on and tested the system. The system is back to heating properly. I emailed the dispatch to the supplied email.

I performed a single heating maintenance on a 2016 carrier gas system. I checked amps, cleanliness, electrical, and safeties. Also, I cleaned the inside of the outdoor panel and resealed a duct. I discovered that the system is full of dust. The number one root cause of system failure is dust. I showed the customer videos and provided solutions to extend the life of the system. Customer stated that he would want to wait until spring to address these issues.

Upon arrival customer stated the heat wasn’t reaching temperature. I placed a call for heat and proceeded to the outside unit as this is a heat pump. I noticed the fan or compressor weren’t running. I tested all electrical components and found that the capacitor was not within manufacturer specifications and was bad. I used my test capacitor to see if the unit would come on. The condenser fan came on but the compressor was humming and trying to start but never would. I then ohm’d out the compressor and it wasn’t reading within manufacturer specifications. The readings were telling me that it was locked up. I talked to the customer about the concerns and provided estimates to have the compressor replaced and capacitor, along with the refrigerant and filter drier for the system. Customer would like to speak to his wife and he will contact us back. Unit will heat in emergency heat mode but will not work in cool or heat mode.

Performed a complete heating system maintenance and inspection. 3 system gas. Inspected and tested all electrical components and safety controls on the indoor unit; all components tested within manufacturer specifications. Verified system temperatures: return air temperature measured at 76°F; supply air temperature measured at 110°F and rising. Confirmed air filter was recently replaced by client; filter size is Aprilaire 813 Inspected and tested all electrical components on the outdoor unit; all components tested within manufacturer specifications. I did notice the den unit and master bed unit both could benefit from having ducts cleaned and blower wheels cleaned. Also spoke to the client about having the outdoor temp sensor changed under parts and labor. The sensor has failed. Also the client brought up that the filter drier is really rusty and would like a quote on getting it changed out. I provided estimates for all cleanings and repairs needed. Confirmed system was
