Downingtown, PA

12/8/25 Tan Performed quality assurance on newly installed Trane heat pump from 12/3. Previously an oil system converted to straight heat pump with electric heat back up. 2 stage system with 10kw electric heat stripe. Client stated noise occurs when it changes from 1st stage to 2nd stage. I found vent that comes directly at top of air handler is the source and that’s where client explained the noise comes from. Majority of the air hits that vent first before hitting the other supply duct so I turned damper to reduce airflow. Noise is reduced and client is happy with changes. Wiring was incorrect as Y2 from outdoor was wired to YO indoor and Y1 from outdoor was wired with Y1 indoor. I made the changes so it can properly change stage. Dip switches set for 3ton on system 310cfm. Total static was close to .7”. When I changed to normal rate of 330cfm per ton, noise was excessive and static increased to over 1”. Confirmed all returns and supply vents open and filter was not restricted. I cha

I arrived for no heat. Customer had told me that the furnace had stopped working and wasn’t coming back on went down to the unit. His phone was saying heat was on, but the board wasn’t doing anything. I reset the unit the furnace came on the board was doing some crazy stuff, bringing on the first stage pressure switch second stage lightning igniter far off the burners then shutting off and then it just started to run steady but I could not adjust fan speeds it was running at 1900 and it’s good to run at 1500 1600 . Customer had told me their power had been going on and off in the fall and they had to replace a board in their stove recommending to replace the furnace. Please check for warranties I collected for my time for diagnostics paid by check.

Luis 12-5-25 customer called in for heater not working. Found heater running upon arrival on an error code pressure switch found water inside inducer assembly drain assembly and test system operation after draining assembly system came on properly. I would recommend adding drain kit on exhaust pipe to prevent this from happening again. I’m also included ez trap for ac drain system since is in series with heater drain. I emailed estimate. As I mentioned it during heat tuneup system goes off on high limit at least once every call for heat. I also provided estimate to add return grill near rerun duct and add two supply grills at the mechanical room. This will help the unit breath better.

Luis 12-5-25 customer called in for heat pump not working ndoor unit attic works but no outdoor found unit off on high pressure lockout reset unit and test operation monitor presses for over 45 mins ok unit did not go off on high head, check air filter 313 ok. System is zone two zones. Second floor and addition area. Maybe issue was when small thermostat was calling for heat and created high pressure. At this time not sure what the exact issue was. Unit is working normally at the time is service. Customer will call back if they still have issues with the unit.

I arrived to the customers home to service their 8 yr old gas furnace system. I started with checking the air filter and replaced , the filter size is 16x25x1.

I inspected the exhaust and fresh air pipe for restrictions and bellies. I inspected the inducer and the blower motor operation. I checked and tested for combustion and took temp rise splits at the return and the supply. Everything is running fine at this time of service.

I arrived back to the customers home to replaced their blower motor in their air handler. I moved the blower housing and remove the motor from the housing mounted new OEM motor placed back in the housing and mounted back in the air.

Ensured proper operation.

Arrived to add the breaker cover for the new tam Trane air handler. Removed the top door and placed the breaker cover and secured the top door .

Installed new Goodman furnace and AC coil. New metal supply transition and new return drop with boot. New 2410 Aprilaire filter box. Adapted to existing fuel line and vent runs. New condensate line with EZ Trap and condensate pump with vinyl running to sump pump. Installed blower surge protector. Installed Ecobee lite thermostat. Installed 2.5 ton Goodman AC unit. Leveled ground and put unit on ground with pad instead of a wall bracket. Installed disconnect with surge protector. Flushed lineset. Tested all operations and clean work area.

Luis 12-3-25 customer called in for noise and outdoor heat pump yesterday doing the inclement weather yesterday, I checked heat pump operation inside outside check all settings. No error Codes are registering on the unit test heat mode and defrost. Ok system is working properly at the time of service. I did increase defrost termination setting to medium. This will provide more time and temperature for unit to get rid of ice from coils. No other adjustments were made.

Estimate

Luis 12-3-25 check heat pump operation Bosch 3 ton unit. Check all electrical connections and components inside and outside ok, test 15 kw electric heat ok. Air filter is clean. Check supply and return air temps. Customer has no use heat pump for heat at all this year. (Main heat is wood stove and pellet stove). Cycle heat pump ok check all sensor and setting on outdoor heat pump control board ok refrigerant pressure ok used control board to check refrigerant. System is working properly at the time of service.

Luis 12-3-25 we recently installed Apco x air purification system, customer was having dirty sock syndrome, she called in because smell still present not at all times, I inspect indoor coils, and ducts. Air purification system is working, did see in previous record from original installation contractor back in 2017/2018 new coil was installed due to same smell. I did sprayed bacteria protection to coil. I did inform customer the next steps we can do, add extra uv light inside coil cabinet, and we can also replace coil. I provided estimate for both items.

Luis 12-2-25 customer called and stating heater sometimes does not heat the home she will set it to 68 room Temperature will be 65 and just cold air blowing through the vents. I increased temperature on the thermostat to get heater operation. Check air filter check supply and return air temperatures 60° differential between the supply and the return. Within manufacture limits. I did replace air filter. I also make sure there was no return bent being blocked restricting airflow back into the unit. I ran unit for over 45 minutes and unit stayed running the entire troubleshooting time. I did tell homeowner to check control module for any error codes. If problem come back coul be related to ignition or airflow issue. System is currently working. Static pressure is .9 wc.

Luis 12-2-25 customer called in for water leak (not sure where water came from) Customer is away and received call from neighbor. Found mechanical room dry, no signs of leaks.
