This morning, I repaired a commercial HVAC system experiencing inconsistent cooling. I identified a faulty TXV (Thermostatic Expansion Valve) and replaced it with a Sporlan valve. Using a digital manifold gauge, I recharged the system with R-410A refrigerant to the correct levels. I also checked and recalibrated the building’s VAV (Variable Air Volume) boxes to ensure even temperature distribution. Finally, I inspected the air handler and cleaned the evaporator coils for optimal performance.

I installed a new Carrier 48HC-D high-efficiency rooftop unit today. First, I secured the 20-ton unit to the commercial building's roof curb per specifications. The thermostat control wiring was connected, and refrigerant linesets were carefully evacuated using a Yellowjacket recovery machine. With a tight vacuum achieved, I charged the system with R-410A refrigerant following Carrier's subcooling targets. The economizer was adjusted for proper ventilation operation.

I completed a repair on a Trane Voyager commercial rooftop unit today. The 15-ton gas/electric unit was experiencing low cooling capacity. Upon inspection, the condenser coils were severely fouled with cottonwood seed debris. Using a 4000 PSI pressure washer, I thoroughly cleaned the coils. The condenser fan motors were seized, so I replaced them with new Genteq motors. After a full system evacuation, I recharged with R-410A to factory specifications. The Trane unit's airflow, superheat, and subcooling were brought back within recommended parameters. Proper cooling is now restored to the commercial space.

I installed a new Hussmann RL4N-G refrigerated merchandiser today. First, I leveled and sealed the unit per manufacturer specifications. The pre-charged refrigeration system was evacuated and leak tested using a Fieldpiece LS3X heated sensor leak detector. Then, the R-404A refrigerant charge was adjusted to achieve optimal superheat and subcooling values. The digital thermostat was calibrated for precise temperature control.

Earlier this month, in Boston, MA, during an annual tune-up and maintenance session for a commercial client's HVAC system, I discovered a significant airflow blockage in a Carrier Infinity system. The blockage was caused by a heavily soiled filter and accumulation within the ducts. I replaced the old filter with a new HEPA filter and performed a thorough cleaning of the ducts. Additionally, I recalibrated the system's Honeywell programmable thermostat to ensure efficient operation. Post-maintenance testing confirmed the system is now running efficiently, with improved air quality and circulation.

This morning in Boston, MA, annual maintenance call for customer. I thoroughly inspected an HVAC system and here are my findings: The return air temperature was 73°F and the supply air was 53°F, resulting in a good 20° temperature split. The total external static pressure was 0.7 WC, with the return at 0.4 WC and supply at 0.3 WC - I recommend checking and replacing the air filter. The blower wheel, evaporator coil, blower run capacitor, and all gas safety controls were clean and functioning properly. The flame sensor was cleaned during the inspection. Both the condenser fan and compressor run capacitors tested within normal tolerance ranges. I have no other additional notes, as overall the HVAC system is in good operating condition without any major issues present.

Responded to a no cooling call in Boston, MA this week. Upon inspection, discovered frozen evaporator coils on the Carrier 25HBC5 air handler. Performed static pressure checks which revealed high external static pressure at 0.9" WC, likely due to dirty air filters. Changed filters and performed complete air flow inspection. Evaporator coil had also lost charge. Evacuated remaining refrigerant, replaced filter drier, and recharged with 7 lbs of R-410A to factory specifications. Cycle tested, ensuring proper superheat/subcooling. Customer now enjoying 20°F temperature split and cool, dehumidified air flow throughout home.

I responded to a service call for a malfunctioning walk-in freezer in Salem, MA earlier this week. Upon arrival, I measured the return air temperature at 28°F, well above the desired setpoint. I performed system diagnostics and determined the issue was a failed evaporator fan motor. I sourced and replaced the 1/2 HP PSC motor and its capacitor, which resolved the malfunction. I evacuated refrigerant lines and recharged them with R-404A to factory specifications, ensuring the freezer maintained -10°F and preserved the client's perishable inventory. I also recommended adding strip curtains to reduce air infiltration and improve energy efficiency.
