I couldn’t be happier with the service provided by Alex. They were willing to price match a quote from another company and Alex went above and way beyond to take care of our system and even trouble shooting an issue that wasn’t his problem. He wanted to make sure everything was perfect before he left. Additionally, it’s rare to find someone so professional in both their appearance and customer interaction and someone who communicates so well. He really explained everything clearly and you could tell he takes pride in his job and work ethic. I can’t say enough nice things about him. He even honored the agreed upon price even though I know he could have charged us way more for the time he spent. It was so refreshing to meet someone so honest and friendly. Thanks Alex and thanks Adon!!!

Upon arrival, the customer gave me more information on the water being in the pan. She stated that the water would over flow indicating that there is a clog present. I managed to locate the termination point under the house. After finding that, I was informed of an issue at the outdoor unit. The condenser fan motor is seized up. I presented pricing to address these issues at the time of service.
Came out today for QC visit on new install. Started inside at t-stat (Trane) turned system down to check over unit. System is level all wiring is good no error codes. Getting over 20 degree temp split. Drain line is draining at this time. System is clean and operating as designed. Outside unit is level all electrical components are good and tight. All components are operating as designed. Pressures were within manufacturer specifications. Tested normal heating operation. System in good working order upon departure. Thank you for your time.

The system does not appear to be cooling efficiently. I advise that a thorough cleaning of the evaporator coil and condenser coil be performed. This will allow for optimum temperature transfer across the coils. 5/20/26 - I returned and performed cleanings of the downstairs evaporator coil and condensing coil. The original supply temperature was 54 and only had a 16 degree temperature split. After cleaning was performed, the supply temperature went to 48.9. This is now a 21.1 degree temperature drop. System is now cooling more efficiently.
Homeowner stated master bedroom was not staying as cool as it should and front of the house was cooler. Reviewed and tested damper operation. Found one damper for downstairs working properly. Found 2 dampers upstairs tied together on one zone. Tested upstairs dampers and found one of them not responding. Reviewed wiring and found loose wiring connection to second damper. Tightened connection and tested again and found all dampers to be working as designed. Tested bypass damper and found it working as intended. Tested airflow in master bedroom downstairs and found this grill to be getting much more airflow than before. This should address the temperature imbalance. Answered homeowner questions about thermostat and adjusted brightness settings so that the thermostat is not shining on her in bed. Advised homeowner to give us a call should there be any further imbalances but I am confident our adjustments today should take care of it. System running upon departure.
Upon arrival, I discovered that the system was operating normally. After further investigation, I found that the system was low on R410a. I provided a quick leak inspection and could not pin point the leak, but I did have oil residue in the evaporator coil cabinet. I went over the options with the customer, and he opted to fill the system up with no warranty or guarantee. The indoor manufacture date is 2017 and the outdoor is 2018. Both units are outside of warranty. The system is cooling with a 20 degree temperature split upon departure. While watching pressures, I noticed that the subcool did not want to come to the target range of 7 - 9. The liquid pressure did not want to come up either. It appears the TXV is stuck open not allowing the refrigerant to flow correctly through the TXV.
I performed a 2 system cooling maintenance. The downstairs is 2020 airhandler and a 2023 heat pump. The upstairs is a complete 2023 heat pump system. I checked amps, capacitors, filters, electrical, drains, cleanliness, and safeties. During my thorough evaluation, I discovered that the downstairs is having a minor cooling issue. I advised performing a deep cleaning on both coils to restore the efficiency of the system. The upstairs is performing well mechanically. However, I noticed the design of the drain needs to be corrected. The emergency drain is completely capped off and will cause water damage when the drain becomes clogged. I presented options for address these issues at the time of service. The emergency drain is capped off. If a clog occurs, it will cause water to backup into the system. The causes a risk of water damage to the electrical of the equipment and the inside of the unit rusting out. Customer opted to do the cleanings and redesign the secondary drain. I performed
Performed a 2 system cooling maintenance. I checked amps, capacitors, filters, electrical, cleanliness, and drains. During my thorough evaluation, I discovered a couple of things that needs to be addressed. Both outdoor units need a chemical bath to ensure proper cleanliness/performance. The unit that services the master bedroom needs a capacitor due to it failing testing during the visit. Customer would like to wait on proceeding with repairs at this time.
Preformed blower wheel cleaning Removal and chemical cleaning of blower wheel rot remove dust causing drag on the motor causing it work harder and ultimately shorten lifespan of the motor.
