I was not home. My wife said John was courteous. Explained what he did and spent time reviewing his findings and recommendations. Overall a very positive experience.
The service was quick but the tech found a problem in that the unit may need to be replaced. That is not a happy thought even though he go the unit cooling better.
They beat the other quotes I had for same hardware
Upon arrival found upstairs unit off. Turned system on and checked inside unit. Found everything operational but filter was caved in. Pulled filter out and filter didnâ€™t appear dirty but once light shines through you could see where filter was getting clogged up. Took filter out and checked pressures outside. Pressures looked ok but sub cooling was low. Outdoor temp was 68* covered condenser and pressures rose up like they should. Subcool went up from 1.7 to 11 and superheat went from 16 to 4. Checked all duct work and dampers, ductwork was sealed up properly and all dampers were open. Checked blower speed and found it on the high speed. Tried adding a little Freon to see if sh&sc would get better and it dropped super heat to 14 and subcool to a 2.6. Took sensing bulb off and rechecked pressures and pressures did not adjust system has a bad txv. Coil was replaced last year in October. Coil still under one year warranty. Will order txv from Lennox. Part ordered in Allen on will call.
Gave estimates to replace upstairs system, gave pricing for a 3.5 14seer 4 16 seer 4 20 seer. Homeowner want availability on 16 seer 2 stage heat/cool. Also homeowner wanted to use a WiFi Honeywell thermostat instead of the nest. Plenums are staying. New whip, armaflex and disconnect and new pad. New drain pan with float switch.
Upon arrival found downstairs disconnect turned off. Turned system on and checked unit. Checked filter and air flow, checked pressures and systems txv was not metering the refrigerant correctly, went to Lennox, pumped system down, replaced filter dryer, pressure tested, pulled vacuum down to 500 microns, purged system and released charge back into system. Pressures looked a lot better and line temps did too. System is now cooling properly at this time. Done under warranty.
Performed a two system maintenance checking cooling. Checked inside units amp draws, drains, mechanical and electrical components and then checked outdoor units pressures amp draws and capacitors. Found that the downstairs system was low on Freon. And recommended a start assist for the upstairs unit. Gave recommendations to replace downstairs and upstairs units. Also gave recommended repairs.
Upon arrival found upstairs unit not cooling. Checked inside unit and found coil frozen. Checked filter and as soon as I removed filter there was a drastic difference in air flow. Filter was clogged pretty bad. Inserted new customer supplied filter. Line set was frozen as well. Shut down outside unit and left blower running. Will need to return once system has thawed out. Explained to homeowner that if filter was the cause of the issue there will be a service fee. Upon arrival turned condenser on for upstairs and checked pressures, pressures were good and noticed the the compressor for downstairs unit was making a funny sound. Checked pressures and found it low, recommended leak search and homeowner approved. Performed leak search and used my sniffer on the coil. Sniffer detected a leak on the bottom left side of coil. Homeowner approved warranty coil. Office will call to get time set up to replace coil. Homeowner wants to pay for coil and leak search at the same time.
Warranty Coil Replacement.
Upon arrival could hear unit making thumping noise on start up. Checked outdoor unit and found that the contactor was burnt up pretty bad. Replaced contactor and sound dampen down. Moved start wire from contactor to capacitor for start relay and that didnâ€™t do anything. Took start assist off of unit and sound went away. Removed start assist and left with customer. Customer would like to speak with office about invoice.
Routine spring maintenance. Only thing noted was 10 degree temp split in arrival. Downstairs air filter was very dirty. Recommended customer change them more frequently, and changed their provided filter to solve airflow restriction issue.
I found Rheem water heater(tankless) has frozen, burst and leaked. We are looking into options on what next step is.
Completed one system fall matience on 2019 lennox furnace. Furnace was still like new and running properly at this time. FILTER IS APRIL AIR 210 and will be ready to be changed come spring time. Estimates for insulation and membership renewal attached.

Also Completed a plumbing inspection. Going to leave estimate for labor to replace kitchen fixtures. Pictures and estimates attached
Checked wiring connection at stat, hub and furnace. Cycled power and tested. Unit is working properly. Customer would like to consider chrome via membership.
Pulled out old coil, installed new, pressure tested, pulled vacuum, and charged to factory specs. Unit is cooling properly at this time.
Completed two system matience on 2 year old lennox systems. I checked operation, voltages, blower motor amperages, filters and safety switches to the furnace. At this time both units are working properly.
