Customer stated that the HVAC system has trouble maintaining temperature in the early portions of the morning. I performed an operational inspection of the air handler and found out that the heat kit wasn't programmed allowing the heat strips to heat the space during lower temperatures and defrost cycles. I spoke with Jesse and was able to program heat strips back into the system and was able to produce heat rectifying heating issues.

System is a 1997 straight electric system. On the first start up, I heared the contactor for the heating strips pulling in and kicking back out over and over. I shut the system down to grab tools. I started the system back up and it worked fine. I cycled it about 15 times and it never failed again. I noticed an excessive amount of growth, a rusted emergency pan, and corrosion on various wires. I suspect it’s a control voltage issue due to corrosion in the thermostat and on the low voltage terminal block. With all I observed, I recommend a new airhandler at the minimum. I instructed the customer to notify us if issue comes back and informed her about the 30 day recall time frame.

Installed new dryer vent silicone driving cap secure drive to the wall hook driver to the dryer

Cleaned dryer vent, dryer vent hose, from 2’ inside dryer itself all the way outside. Needing an estimate to replace the dryer vent cap with 12 inches to slide inside the wall. Needing an estimate to include anchor screws to secure vent cap to outside brick and into caulk all the way around to keep moisture out.

Info

Performed signs system heating maintenance. Checked amps, capacitor, filter, electrical, cleanliness, and safeties. System is heating to manufacture specifications. I installed a ss1 float, Ss3 float, and rebuilt the secondary drain to bring it down closer to the pan to reduce the chance of water splatter. Recommendation 1. Performing a blower cleaning due to excessive dust build up. This makes the blower have to work harder and can cause premature failure.

Found that the indoor unit has splotchy supply power coming from the main breaker panel causing some wires to burn. Customer needs some wires repaired and an electrician to determine which breaker is which due to none of them being labeled.

The original technicians from the Sears company installed a filter drier in the attic next to the air handler. This has to be rectified and removed due to ongoing refrigerant restriction causing the heat pump to fail. The customer stated that this problem has occurred since the first day of installation. Upon arrival, the system had a hard lockout due to ongoing trouble code on the system. We were not able to bypass the lockout to pump down the system to remove the filter drier next to the air handler. We also attempted to call Carrier tech support for assistance but after an hour of being on hold we were unsuccessful. Another attempt will be made to reach to tech support tomorrow to resolve the issue. Homeowner was informed of the situation and return visit to their home.

Perform system maintenance on a 2024 3 ton Trane air handler with a 2020 3 ton carrier condenser tested all components on air handler everything working within manufacturer specifications. Checked outdoor unit and found the outdoor capacitor is under the maintenance specifications of replacement. Recommend replacing capacitor Below the 6%rang of manufacture recommended replacement.

According to Carrier tech support, the HVAC unit is in need of adding the proper charge of refrigerant to rectify suction pressure temperature fault. After running system in AC mode at 100%, there was a sign of restriction due to high subcool and superheat. The heat pump has a filter drier inside the unit and outside the air handler in the attic. One of the filter driers must be removed to restore proper refrigerant pressures and eliminate periodic system faults.
