Luis 6-24-26 Performed tune up on 6 month Goodman two ton system, check indoor and outdoor units electrical components and connections, replace 20x20x1 filter, test ac operation check refrigerant levels and pressures ok system is working properly at the time of service, verified air flow ok bower speed f4 around 360 per ton, customer is very happy with new system.

There are (3) systems in the house. 1.Basement (1st Floor) Uplflow Lennox Icomfort thermostat with (2) zone thermostats. 2. Second floor system; furnace horizontal right in mechanical room across the bathroom on third floor. * Today’s problem system, 3. Second/3rd floor system furnace in 3rd floor bedroom closet. *This is the system Kurty identified refrigerant leak and charged on 6/1/26 Todays call was concerning the other 2nd floor system (horizontal right). 3 Ton AC/Gas Furnace 11 years old. Found refrigerant leak at indoor coil using electronic leak detector. System is considerably low on refrigerant. Running at 60 psi. Discussed various options including replacing HVAC system And replacing indoor coil. They wanted to charge the system for now. Charged system 4# R410A refrigerant Final pressures 221/116 6.6° SC 14° SH. Outdoor temperature 68° We cannot guarantee how long refrigerant will last. My professional recommendation is to replace the (2) second floor HVAC systems. Bo

Luis 6-15-26 Performed quality assurance corrected all issues with system. Corrected zoning issues. Extended drain line so it drains away from house. Insulate ez trap. Fix low voltage wires not came off as I was testing, zoning board makes humming sound. I had to open zone board door to prevent any vibration on master bedroom area customer stated humming sound all nights. We need to keep zoning panel door open to prevent vibration, test all zones ok. Replace air filter. 16x25x1. Management attention I will talk to the, about this job for further evaluation

Completed AC tune up for 3 Ton Heil AC system System was installed by another company in 2021 Aprilaire 413 filter ok Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; left estimates for surge protector for outdoor equipment circuit. We installed blower motor surge protector with new funace in December Measured temperature split and static pressure Inspected drains; cleared EZ trap, tested pump; added treatment tabs to drain pan. Checked integrity of compressor motor (mega ohm test) Assessed refrigerant charge checked pressures. 10° SC matches manufacturer target. AC system operating well at this time.

Quality assurance for left-side system. 4 Tons upflow air handler on second floor. Returns are on second floor. Thermostat on second floor hallway wall. Remains at 81° therefore system stays on in cooling. Overcools rooms below but thermostat does not satisfy because 1 it is reading 2.50 high and 2. There is no supply in hallway.(Thermostat is reading 2.5° high when compared to 2 of my temperature probes, see photos) Solution here is to install a S1200 smart thermostat with a room sensor and place the room sensor in a better location) 1st floor for example They may be interested in adding a supply to the hallway ceiling. It is a plaster ceiling and there is no easy access to the space above. The one access (in front of air handler in same room) has several screws and the drywall gave away when I tried to open. Presumably this will only open up to the eves of the attic space. Adding a supply to the second floor hallway ceiling is no small task. Will require a sight visit. I would l

The right side system is 2.5 Ton AC only air handler. Thermostat for this system also controls a hydronic zone so it is a heat cool thermostat. Air handler located on first floor. Filter size is 16x20x1 Inspected all aspects of install: mechanical, ductwork connections, wiring, controls, refrigerant charge etc. Used blower chart to determine that speed tap 4 is preferred over factorytap 8. Tap 4 will move 1160 CFM @ .8” static Temperature split is 20.5° 8° SC 7°SH Install passes QA inspection.

Luis 6-10-26 Replacement of water heater under warranty no charge. Check water pressure 60 psi. Installed water alarms back in place check water flow and Temp ok. Showed customer how to increase temperature in case she ants hotter temperature. Currently set to A.

6/6/26. Fully assessed water in pan at water heater that was installed by dibiase 11/25. Shined bright light on water heater and inspected for leak. Checked all the connections on top all were dry. Felt around bottom of water heater and found it do be wet. Dried everything up and took off metal plate for burner compartment. Found foam was wet along the bottom and found water inside at bottom of water heater. Water heater has a very small leak from tank. Water heater needs replaced. Our office to order new water heater. Put leak detection back in and showed homeowner how to turn off water in case of emergency.

Luis 6-4-26 Performed ac tune up on 3.5 ton American standard heat pump. Check indoor coils and electrical components ok. Inspect drain test pump ok. Drain trap connection came apart I provided estimate to repair 3/4 drain line with new tubing, I also provided to upgrade to safety trap customer will take care of issue. Inspect coil contamination system ok. Check outdoor unit refrigerant levels ok all electrical components outside ok. Cycle heat pump ok. System in good operating condition at this time. Customer renew service plan.

6/1/26. Fully assessed no cooling situation on 2015 Lennox a/c. Checked temperature split it was 17 a little low. Ran leak detector across evaporator coil and found refrigerant leak ( took video). Checked 410a refrigerant pressures they were 225/86 with 1.4 subcooling and 42 superheat. Explained to homeowner that we have 3 options. Just add refrigerant which we don’t know how long it will last, replace evaporator coil fo between $4,000 to $5,000. Or replace a/c system. Explained to homeowner this is a free charge to have someone come out to give a replacement quote. She decided to just add the refrigarant for now. Add 2lbs 410a pressures are now 234/121with 5 subcooling and 18 superheat . A/c is working at time of service.
