I called in the morning to describe an AC problem and they set up an appointment ..... they arrived ahead of time and were very professional. Problem solved, plus they gave me a quote for a new system, which I requested, during the same visit.

Ok service, ok associate
Angie - Exton, PA
everyone I've talked with or worked with previously was great. This particular associate needs a little refresher in customer service. When asked exactly what service(s) he'd be performing as part of the check up, he looked shocked as if he'd never been asked that before then struggled to find the words. When at the end he indicated a part was needed and I asked what the part was and what the issue was, he actually said "how do I explain this". I'm well educated son, I'm pretty sure if you use English and explain it at a laymen's terms, I'll be able to understand.
Great Service, Great Team

Performed Precision Air Conditioning Tune Up on system. Changed the 20x25x1 Air Filter. Cleaned Condensation Drain Pipe. Inspected Electrical Components on Indoor and Outdoor Units. Found 2 Pole Contactor on Outdoor Unit was worn and Pitted. Recommend replacement of the Contactor. Measured Refrigerant Charge on system. Refrigerant Pressures were slightly elevated and Subcooling Level was higher than normal. The Outdoor Coil is dirty which can block Air Flow and increase Pressures. Due to no Water Hose Connections being available, the Outdoor Unit would have to be power washed to clean the Coil. The system appears to have Leak Dye in it which would indicate that Refrigerant was added at some point. The system could also be slightly overcharged which would increase Pressures and Subcooling. Amp readings on the Compressor are within range.

Service call that the AC for the Second Floor was not working properly and was shutting on/off. Customer also informed me that it was not keeping temperature properly. After troubleshooting system, found that the system had a restriction in the TXV and was starving the Evaporator Coil causing the High Superheat Levels, and then the eventually causing the system to pull down and shut off in low Pressure. Need to replace the Mechanical TXV and retest system.We will return Tomorrow Thursday 8/30 between 12p-2p to perform repair work. The office will follow up today to confirm scheduling.Returned to site to replace the TXV. Shut system down and pumped Refrigerant back to the Compressor.

No ac . Found unit running but low on charge . Homeowner said the system was fine after we charged it up a few weeks back . But Saturday the fan was not working . I tested the fan motor . Fan motor was pulling 1.8 amps . Capacitor on the fan was a 15uf reading 13.9uf . Air filters looked clean after I pulled them out to expect them . I checked the coil . After I pulled off the inspection plate on the coil I saw that the coil was ok . I looked into the return box to see if anything was blocking the return air flow . That was good . The temperature split was only 10 degrees. Return was 77 Supply was 67 . The charge was low . Low 69 high 249 supper heat 57 subcooling 1.1 . System is a piston. I added 2.5 lbs of refrigerant that is not going to be charged to the job . Then I added dye into the system to find the leak . I told the homeowner that we could come back in a couple weeks to check for the leak .

Ac tune up . Checked filter . Cleaned pump and trap . Tested low and high voltage readings and wiring. Checked capacitors. Tested air temperature splits and refrigerant charge . Tested overall system . I found the outdoor units fan shaking the hole system . I believe the fan blade or shaft are bent and out of balance . I would recommend to replace them due to the outdoor unit shaking . Refrigerant was a little low . It could be because of the fan blade and motor not moving enough air . I would check the charge after replacing the parts . I explained to the homeowner about the parts that need to be replaced. The homeowner would like a quote on a new system before replacing the parts on the old one . I called the office to scheduled a time for joe to come out and give a quote ,
