Excellent Plumbing Service

Dee was so friendly, professional and helpful. I crushed my ankle and am in a wheelchair presently. He offered to bring my trash bins in from the curb & p/u a delivery for me that was left outside. He described what to expect and worked all day. He has almost 19 years plumbing experience, I highly recommend him regarding your plumbing needs.

For this job, I completed a two system full inspection. I tested both units in heat and cool to ensure that everything was working. I inspected the blower wheel and burners. I measured all the electrical components, as well as proceeded to inspect the outdoor unit and get all electrical component readings, as well as pressure readings. In my findings, I noticed that both condenser coils were dirty. I Explained my findings to the customer as well as provided estimates in which he agreed, and i proceeded to get this job done.

Performed 1 system diagnostic for system that services whole home. Unit is R22 furnace is. 19 years old and ac condenser is 25 years old. Found failed OFM,failed dual run capacitor, failed run capacitor, dirty blower wheel, improper gas connections, blower drawing high amps. Due to the age of the unit and cost of repairs would recommend replacing system replacement of the system. Unit is non operational at this time. Would not be able to complete work today due to supply houses being closed. Based on our findings today, it might be time to think about getting a brand new system.

Did Inspection for 1 system in home that is zoned and has 13 zone dampers attached to it Customer er stated they will change Aprilaire model 413 system filter. Customer advised me that they were having air flow issues within the home. Stated that some areas weren’t getting as good as airflow. Found that 6 zone damper failed. Qty 1: for zone 3, qty 1: for zone 2, qty 4: for zone 1 that will need replacement. Customer approved to have all 6 that failed replaced. Checked over all of system, system is in good shape, outdoor condenser coils were very clogged. Recommended cleaning to help system performance, customer approved to have done as well. Everything inside cabinet is nice and clean. Outdoor capacitor and contactor tested good with no issues. Will follow up with customer Monday about part availability and get them schedule to do repairs.
