Great technician—Super knowledgeable and personable. It was a pleasure dealing with Kurt.
Performed 6 month inspection on mini split system for the basement, and performed 2 precision a/c tune ups on 2 amana a/c systems. Cleaned washable filters on mini split system, replaced 2 Aprilaire 413 air filters on 1st and 2nd floor a/c systems. Blew out all condensation drains. Checked temperature split on all a/c systems. Checked refrigerant pressures and temperatures at indoor and outdoor units. Systems are working fine at time of inspection.
Performed Quality Assurance on Daikin Mini Split system. Reviewed installation with homeowner. Tested unit in both heating and cooling modes. Completed checklist form in system.
Installed new txv at air handler. Also put down 3/4 plywood in the attic for walkway. After installing new valve, pressure tested and leak checked at 200 psi nitrogen. Put system on vacuum pump and pump system down to 400 microns. Released charge pulled back in condenser and performed quality assurance inspection. Temperature inside was a little cool during testing process only 62 degrees. Checked all electrical conections and components. Checked refrigerant pressures at outdoor unit. They were 206/ 104 with a subcooling of 26 and a super heat of 15. Covered outdoor fan and pressures were changing with fan being covered. System is working fine at time of service. 24x24x1 air filter is clean.
Reclaimed and removed old equipment. Leveled new condensate pad and installed new Amana condenser with new disconnect and whip. Flushed lineset and brazed in with nitrogen. Installed new Amana air handler and brazed in with nitrogen. Pressure tested to 300 and evacuated to 132 microns. Reconnected electric with new disconnect and tied in low volt wires with ez trap and wet switch safteys. Reconnected supply and return ducts and sealed. Reconnected condensate lines. Installed new Honeywell t6 thermostat. Went to test system and found bad txv from factory. Will return to replace and test again.
Reclaimed and removed old equipment. Installed new daikin heat pump on new leveled pad and ductless head. Installed new whip, disconnect, and surge protector. Installed new lineset and flared into both units with flare tite seals. Pressure tested to 400 psi and checked with bubbles. Evacuated down to 65 microns. Replaced all linehide and installed new pump for condensate. Tested system operation. System running perfectly at time of install.
Performed ac tune up check electrical low and high ok replace air filter check blower and coil flushed drain ok check outdoor unit refrigerant pressures capacitor and contactor ok noticed condenser fan motor pulling 1.5 amps and rated at 1.5 informed customer and recommended having system replace bill to come out on Wednesday at 10 am for new system replacement attic
Daiken mini split unit not working, upon arrival found unit off, after talking to customer, they said unit was not coming for cooling or heating, set unit for heating and 86, unit came on check supply and rerun temp supply 120 return 70, explained to customer that mini split ac mode does not operate when outdoor temperature is below 50 but also by having dirty filters and blower housing unit runs below freezing and prevents the unit from coming, blower housing/wheel and coil needs to be cleaned, and also unit need to come off the wall to insulate both lines behind unit, if new piping is required we will informed customer additional cost will be required if new piping is needed, emailed proposal for repairs removed indoor unit from wall insulate lines and clean blower wheel, also we will be sending proposal for new system replacement
Performed ac tune up check electrical low and high ok replace air filter, flushed drain test pump check blower cap ok check split, check outdoor unit refrigerant pressures capacitor and contactor ok, recommend adding hard start kit to unit quoted but customer would do it next year, also performed water test water has 10 grains of calcium and magnesium chlorine levels are in the middle emailed customer proposal for water treatment systems
Found no surge protection on ecm blower motor for first floor or second floor blower. Added surge protection to both systems. Performed precision peco heat tune up on 2 Lennox heat pump systems. First floor system has a 20x20x5 filter, second floor air filter is 20x25x5(homeowner to replace both filters). Checked all electrical conections and components. Checked refrigerant pressures and temperatures at indoor and outdoor units. Both systems are working fine at time of inspection. Do recommend switching over to high efficiency propane systems, homeowners are not very comfortable with heat pump systems. Found no surge protection on second floor blower motor
Performed precision heat tune up on trane heat pump. Replaced dirty 20x22x1 air filter. ( recommended to homeowner to change more often, showed her how to change it). Checked all electrical conections and components. Checked refrigerant pressures and temperatures at indoor and outdoor units. System is working fine at time of service. Installed surge protector.
Ran 10inch Return to the new room as well as a 6 inch supply vent. Put in mini split with outdoor unit ran line hide new disconnect drain and refrigerant lines inside line hide ran new power wire and tied into electrical panel with new 20 amp double poll breaker unit was triple evacuated and held pressure for 25 minutes. Unit was vacuumed down to 100 microns and held for 20 minutes... system is charged and running to factory standards. Went over everything with customer.
Replace gas valve on first floor system test and cycle furnace ok check for gas leaks on work performed no leaks combustion test ok system is running at no issues
No heat return visit to continue troubleshooting, after checking gas pressures incoming and manifold, check all grounding, furnace drain, found out bad connection on gas valve, contact Amana tech support and both agreed that gas valve should be replaced,
No heat, found furnace running upon arrival, check heater operation and test ok check errors on history found E0 ignition lock out, check all electrical, ground wire ok, check pressure switch and tubing ok, could not get furnace to failed did not din any issues, talked to Amana Rep, and he recommend to check heat exchanger for any leaks, inspect exchanger found lot of areas with rust, looks like condensation is getting to exchanger, could not check exchanger with my camera we will need a High definition camera and try to inspect heat exchanger deeper, return visit is need to check heat exchanger
Installed new pressure switch under warranty. Also found one of the pressure switch hoses to be a little loose. Re secured pressure switch hose with zip tie to make tight connection. Ran furnace for about 20 minutes and had no issues with it cutting out on any error codes. Also checked outside exahaust vent for debris, vent is clear. As furnace was running it displayed an e3 error code which is high limit code. Increased fan speed by 5% trim to help with temp rise. Now have a 51 degree temperature rise. Homeowner also would like an estimate from our office to add supplies and returns downstairs off of existing duct work.
