Upon arrival, I performed inspection on indoor unit verifying proper airflow across indoor coil. Checked temperature differential and found only a 11°F temp differential. Proceeded to outdoor unit and checked refrigerant pressures. I found super heat at 55° F and rising. This indicates the indoor coil is not receiving enough refrigerant. Unfortunately, since system is R 22 refrigerant I am unable to add refrigerant or make any refrigeration repairs. I recommended homeowner gets estimate to replace system.

6-12-25 Luis Performed ac tune up on 3.5 ton American standard heat pump and trane air handler. Indoor unit is from 2004 heat pump from 2017. Check electrical low and high voltage connections and components. Flush drain test pump noticed drain pan collects lot of water before starts draining. Check supply and return air temperatures. 18 degree split. Air filter would not come out without breaking. Provided estimate to upgrade to 213 filter kit. (We will need to do this when filter gets replaced). Went outside and check heat pump refrigeration levels and pressures ok cap and contactor ok. There is low voltage connections that insulation is breaking, provided estimate to replace low voltage wire from splice to outdoor unit. Customer approved repairs and were completed on today visit. Installation of April air upgrade kit Replacement of low voltage wire on outside unit will need (5 feet)

Performed quality assurance on recently installed unit air handler and AC unit check all settings on indoor and outdoor units inspect water safeties check and inspect drain ok. test performance check air flows supply return air temperatures went outside and check all electrical disconnect concrete pad ok system is running within manufacture specifications.

Reviewed home for energy and comfort solutions. Recommend air sealing and insulating attic space and also replacing hvac system with new system.

Checked the AC side of the system . Checked the air filter and replaced. Checked the wiring connections and the voltages on high volt and low volt. Inspected the indoor coil and flushed and tested the drain line. Checked the blower condition and inspected the blower amps and tested for static pressure. Went to the outdoor unit and inspected the wiring connections and the components . Checked and tested the pressures by using superheat and sub cooling methods. Checked the amps for the compressor and the fan motor and checked the indoor cooling temps at the supply and return. The AC system is working fine at this time of service.

Did a QA on a new trane 2stage gas furnace . Check the cleanliness of all the wires and connections. Inspected the gas line to check for leaks . Checked the flue piping and checked the drain lines. Checked the control board for proper set up and checked the thermostat for set up. Checked outdoor level and the disconnect level and made sure all penetrations are caulked . Tested the a/c system operation, found refrigerant charge was good. Talked with the customer to see if he had any questions. I helped the customer set up her schedule for the thermostat. The new system looks good. It’s up and running at this time of service.

Issue was water leaking on to floor. 3 Ton heat pump with 10KW electric heat. Air handler downflow on second floor. Tested system. Refrigerant levels very low running at 79 psi… Unit has been freezing up as a result of low refrigerant pressures. Blew drain clear and poured water to test. Created estimates for repairs. 1. Charge system up to 3# R410A 2. plan membership, charge system, add leak detection dye, install ez trap 3. Plan membership, charge system, install ez trap, install clean out tee, install hard start kit for outdoor unit. Discussed consultation for system upgrade options. Scheduled consultation for both home performance and HVaC system upgrade 10AM tomorrow Charged diagnostic today.

Return visit to check for refrigeration leaks. I did change filters. And inspected coils indoor and outdoor. Refrigerant pressures are within range. I was not able to see any dye signs. Customer will run unit as normal and would call us when they have an issue.

Checked the AC side of the system . Checked the air filter and found good . Customer replaces his filters. Checked the wiring connections and the voltages on high volt and low volt. Inspected the indoor coil and flushed and tested the drain line. Checked the blower condition and inspected the blower amps and tested for static pressure. Went to the outdoor unit and inspected the wiring connections and the components . Checked and tested the pressures by using superheat and sub cooling methods. Checked the amps for the compressor and the fan motor and checked the indoor cooling temps at the supply and return. The AC system is working fine at this time of service.

Performed precision a/c tune up on (2) American standard a/c. Replaced (2) Aprilaire 413 air filters. Checked all electrical connections and components. Installed (2) zap pro surge protectors for both indoor gas furnaces. Checked temperature split. Put tabs in condensate pumps. Checked refrigerant pressures and temperatures at indoor and outdoor units. Replaced weak capacitor for 1st floor system. Capacitor was a 45/5, tested at 40/5. Tested operation. Both systems are working properly at time of service.

Performed precision a/c tune up on trane a/c system. Homeowner just replaced aprilaire 413 air filter. Checked all electrical connections and components. Checked temperature split. Inspected drain line. Tested outdoor capacitor. Found contactor burnt and pitted, replaced contactor. Checked refrigerant pressures and temperatures at indoor and outdoor units. A/c is working at time of service.

need to return with extension ladder.

Performed 6 month inspection on 3 ton trane inverter system. Went over system indoor and outdoor units. All settings ok test performance trough technician app. All numbers within range. No errors showing. Cycle heat pump ok. Flush drain ok.

Perform ac tuneup on amana and Luxaire heat pump systems. Replace 20 x 22 x 1“ air filter and 16 x 20 x 1“ air filter. Checked all electrical connections and components. Check supply and return air temps and flows ok Tested capacitors and contactor Check refrigerant pressures and temperatures. Inspect coils ok. Both systems are running within standards. Provided estimate to add air purification system on each unit.

When I arrived homeowner showed me the microwave and asked if we vent microwaves to the outside, explained to her that we don’t.

Perform AC tuneup on a 3 ton air handler/outdoor Lennox system. Customer just change filter. 20x20x1. Customer also stated system was not cooling correctly. Set thermostat to cool and checked operation. Outdoor unit would not come on. No power to outside unit. Found defective 30 amp breaker. Provided estimate to replace breaker. Customer approved estimate. Checked supply and return airflow and temps. Flush drain inspect indoor coil and blower. Checked outside unit found unit to be low on refrigerant. Provided estimate to add refrigerant and dye. I also provided estimate to install potential relay and start capacitor. Customer approved all repairs. Added total of 3 lbs of refrigerant and dye. Pressures and temps are in good working order. We will check system for leak once we come back next spring unless customer has an issue this summer.

Performed a QA on a heat pump system. Took photos of the equipment and looked at the overall install of the indoor unit and the outdoor heat pump. Looked at the wiring connections and the voltages.

PECO shut off gas to Amana natural gas furnace. They were picking up gas on the outlet side of the valve after valve had closed. I tested today. There is gas on outlet of valve after it closes. Took video and photos. I shut gas shutoff valve to furnace back off. Contacted HVAC distributors and confirmed warranty status. It is ordered and will be shipped to shop on tomorrow’s delivery under PO Service/Stell. I presented warranty gas valve replacement. Homeowner approved. Also completed quality assurance for Minisplit. Checked all aspects of install. Tested in heating. Temperature rise: Good Walked through filter cleaning and use of remote with homeowner Homeowner paid for warranty gas valve replacement today. We will schedule ASAP.
