Everything was excellent
No hot water at indirect water heater due to bad zone valve, stem was not making connection to end switch inside valve causing system to only heat hot water when heating zones are calling for heat, noticed corrosion on other two zone valves for 1st and 2nd floor which would of caused zones to receive no heat or too much heat, replaced all three zone valves, purged lines and added antifreeze back into boiler, tested antifreeze levels and found levels to be satisfactory. Explained in details to customer why zone valves needed to be replaced and why zone valve for water heater isnâ€™t making contact to end switch. Also recommended replacing 1inch ball valve at indirect water heater, looked like it was leaking.
No hot water indirect. Arrived and boiler was already making hot water, all pipes supply and return for indirect zone were hot. Hot water coming from faucet. Tested zone valve for indirect to see if it was getting stuck, fully opened and closed each time. Circulator running for call for hot water. I may have hit wiring to zone valve when performing cleaning wires were hanging right where I was vacuuming and brushing. Let system reach temperature and watch valve close. Unit running normally.
C/S oil. Replaced filter strainer and nozzle. Brushed and cleaned heat exchanger. Checked all components. System running normally.
Completed annual maintenance on two AC systems with MA. Customer stated during the mini heat wave last week first floor wasnâ€™t keeping up to temperature, checked filter which was good, coil clean of any debris, fan amp readings normal, air flow seemed fine, had a 22 degree delta t reading, pressures were normal, everything working at this time, if problem happens again will need to diagnosis when itâ€™s happening right now everything operational.
Completed annual maintenance on three mini split indoor units and one condenser, all filters were cleaned and still clean, cleaned indoor coils, took delta t readings of all three units which had a average of 21 degree split, all remotes working, at condenser tested pressures which were normal system was just charged by us two days ago, condenser coil clean, wiped down unit. Systems operational and working, reset all remotes to where temperatures were.
Arrived and found the one unit that was not cooling well running upstairs. It was running okay and cooling just not very efficient. Checked pressures with the one running and they were low, checked pressures with 2 head unit running and they were still low. The temperature split continued to drop at the upstairs unit as each one got turned on. Added refrigerant and uv dye to the system. Checked pressures after repairs.
Found second floor head unit with a 6 degree temperature split. Both first floor units have a 24 degree split. Have to return during business hours for Fujitsu to call tech support. Filters were all cleaned upon arrival. Low side 132 superheat 6
Found male adapter for condensate drain line going into condensate drain pan leaking. Removed and found Teflon tape worn. Replaced male adapter and re wrapped Teflon tap. Dried the tiny bit of water out of pan.
Performed annual AC tuneup on 2 systems. Attic unit had weak capacitor. Replaced capacitor. Tested units. Systems operational. Attic unit appeared to have mold inside of blower and coil compartment. Highly recommend UV light for attic unit. Recommend to duct cleaning.
No ac. Customer had a leak at unit, water came down to first floor ceiling. Customer cut back drain line and unclogged himself, customer also had a crack in emergency pan which caused overflow switch to not activate due to pan losing water. Customer sealed crack with flex seal, tested pan and water is not leaking out of pan. I also cleared drain line with 3 CO2 cartridges and saw water leaving coil pan into drain line. Also found filter plugged up which was giving the customer an issue air not feeling as cold, r22 system, pressures were ok delta t was 15. System running normally.
No ac second floor. Found unit low on 410A. Filter, coils were both clean. Added refrigerant, got SC to 15, rated for 14 degrees. Temperature split was 18. Supply vents coming out at 63 and return vent 81, thermostat reading 81 degrees, customer needs to let system run to remove hot air from second floor for supply temperature to begin decreasing. Unit was in installed in 2019 by a company in Connecticut, informed customer there is an obvious leak somewhere in system, informed him I could perform leak search, customer would like to contact company who installed unit first to find out about his warranties. System is running normally.
Performed annual AC tuneup. Tested unit. System operational.
Found first floor zone valve stuck open. When boiler makes hot water, sending heat through first floor hydro coil. Replaced first floor zone valve head. Also cycled ac system multiple times and checked system running pressures and temperatures.
Ac tune up. System 1 year old. Checked temperatures, cleared drain line, checked blower motor. Took pressures, tested contactor and capacitor. Found 20x20x4 filter plugged up. Replaced, system running normally.
No issues to report system operational checked pressures, temperature splits everything right where it should be.
