Replace main board, driver board, compressor thermistor, and eev. Also repair damaged wires.

Pump refrigerant down into unit, disconnect piping, mount wall stand, mount unit, reconfigure and connect piping, pressure test, pull vacuum on system, open lines back up, operate unit to verify no problems. Repeat same process on other system.

Completed a walk-through of the mechanical room and the overall building and everything looked good.

I replaced all the filters for the rooftop unit. I replaced all the filters for the indoor units located in the ceiling.

Every thing looks good.

I washed the indoor coils with Dawn soap and water. I cleaned off the air filters. I noticed outside there is a piece of the cover garden missing.

Filters

Replaced 3 20x20x1 air filters and 1 20x24x1 air filter on the upstairs air handler.

Laars Neotherm boiler maintenance. Everything looks great.

Modify the existing bathroom fans, which currently share a 4" vent via a tee fitting that goes to the exterior gable end. Insulated 4" flex venting will be installed for each run, leading to the gable end exhaust. The current exhaust will be replaced, and a second exhaust will be installed for the second fan. All runs will be insulated with R8 to prevent condensation.

Rinnai tankless maintenance went great. The heat exchnager was dirty! The inlet screen has sediment in it as well. Right sink drain in master bathroom needs a new pop up drain tail piece. It is leaking. It also drains slowly. I reccomend replacing it instead of taking it apart. The upstairs bathroom sink drains slowly, it should be taken apart and cleaned. I replaced two toilet flapper valves today on the toilets that had a weak flush.

Plumbing repair at a residential home. Arrived to address a leaking tub spout and quickly identified a worn-out washer as the cause. After replacing the washer with a new one, the spout was restored to proper working condition, eliminating the leak. The customer was pleased with the fast and efficient repair.

Add zoning system with minimal ductwork to provide supplemental heating for the newly finished basement space. Zoning will provide independent control over the system for the basement. A bypass is installed which will allow the required minimum airflow to move through the system to protect the heating & cooling system.

Install basement zone.

Replaced shower valve

Replace the control board on the shop furnace. We believe this is the cause to the intermittent shorting of fuses.

Repairs flue pipe going into chimney. Seal with high temp furnace cement. Install brackets to secure flue to chimney. Replace expansion tank and relief valve on water heater.

Purge all zones of air causing heating issues. Replace failed circulator pump, relief valve, and air vent.

I replaced all on the indoor filters.

Mini split maintenance Heating 1, on a 4 systems.

First I started off with replacing the 3 air filters in the ceiling down stairs. I then went upstairs and replaced the air filter for the air handler. I inspected electrical connections and everything looked good. Finally I went outside and I tested the capacitors on the heat pump unit and they were in spec.

I started off with cleaning the indoor coils with hot Dawn soap and water. Next, I clean the filters with water. I wipe down the outside of the unit with a rag. I checked the supply temp coming out and it was around 110°. Then went outside and checked the electrical connections on the outdoor unit. Everything looked and operated well.

All three of the gas furnaces were maintained in this same order. I started off with cleaning the flame sensor. I then checked the capacitor and everyone was in spec. I checked all electrical connections to make sure everything was tight and not damage. I inspected the burner tubes and they all looked good. I did a visual inspection on the outside and on the inside of the furnace to look for leaks or corrosion and they all looked great. I replaced the 20x25x5 Air Bear filters. I checked natural gas pressure incoming and at the manifold and they were all perfect, none needed to be adjusted. I bubbled and used an electronic leak detector after I disconnected my manometer from the gas valve. Lastly, I used the combustion analyzer to make sure my oxygen, CO2 and CO levels were in range. Every furnace had good combustion readings.

I started off with removing the old condensate pump. Next I installed the new condensate pump with neutralizer beads. When I plugged the pump in it kept running and never shut off. I found that the float switch was sticking. The new condensate pump was faulty from the factory, so I got a replacement one. After installing the new one, I poured water into it to test operation and it worked as it should.

Removed burners to clean them
