Arrived for no cooling. Equipment is 3.5 Ton heat pump installed 8/18/23 by another contractor. The air handler dates to 2011. As I passed by outdoor unit I could hear compressor trying to start. Condenser fan was running. Began diagnostics at the outdoor unit. 45uF capacitor tested within range. Found compressor very hot to the touch. I cooled with water 7 min. Megaohm test: Pass on all (3) compressor windings. Tried (2) different kind of start assists to free compressor but to no avail. Also ran system in both heating and cooling to exercise reversing valve and checked pressures switches. They are in proper closed position. Made sure System has refrigerant (187 psi standing) I do not recommend replacing the compressor as the air handler is 15 years old. After discussing with management our only offer is to replace the HVAC system entirely. There is too much risk in dissatisfaction and equipment failure to offer replacement of the compressor alone. Consultations do new systems ar
Basement 90% furnace/AC-(TRANE) -Arrived on site and spoke with customer -Was told system is running but not blowing out cold air -Verified operation on system and verified pressures -System was severely low on refrigerant (hi-200 lo-190) -A return visit is needed and system will be leak searched & charged properly to insure operation (additional charge if we need to add dye/sealant) -System is currently inoperable and a return visit is needed 5/22/26 Ultimately determined that compressor is not running at all for second floor system (but condenser fan is). 45/5 capacitor Good. Tried (2) different kinds of start kits but to no avail. Outdoor units and furnaces were replaced in 2018 but the original indoor coils were kept! Indoor coils are 20 years old. The only warranty remaining is for furnace heat exchanger Standing pressures 165. There is refrigerant in system. Did a complimentary electronic leak search on indoor coil and brazed joints.

No cooling 1st floor system 4 Ton Heat pump. Homeowners had turned power off to breaker for outdoor unit. Turned breaker back on. Found system running at very low refrigerant levels. Did a complimentary electronic leak search. Could not pinpoint leak. Recovered and weighed what little refrigerant was in system 24oz (Factor charge is 244oz) so system lost 82% of its charge. Lineset is approximately 15’ Pressurized system to 330 psi with dry nitrogen. System held this pressure 35 min. See photos. After The leak could very well have been a schrader core that re-seated when I put my hoses on. We will leave system under pressure. Return early next week and check pressure. If there are no other leaks we will replace all schrader cores, evacuate then charge the system. Left disconnect to this system outdoor unit off. Second floor system still operating. They can use indoor fan for first floor system.
Loss of power to thermostat was caused by a blocked trap in drain line. There is a float switch in the SpacePak drain pan which when acts on by backed up water from drain, broke power to the thermostat. Cleared drain line easily with brush then flushed line with 1.5 Gal. Water. The drain line terminates at a plastic keg that the previous homeowner used for store the water for gardening After clearing drain I completed AC tune up. Equipment is Bosch heat pump/inverter installed by a contractor during renovations of the house in 2021 Replaced 14x30x1 filter the (2) 14x20x1 filters ok Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; left estimates for surge protectors. 1 for indoor equipment and 1 for outdoor equipment. Measured temperature split and static pressure Inspected drains; cleared trap. Assessed refrigerant charge checked pressures. 8° Subcooling: Perfect AC system operating well at this time.
Homeowner informed me that the system hasn’t been working. When I arrived the zone panel was indicating that there was a demand for heat for, both thermostats but the furnace control displayed Idl “idle” Ultimately discovered that the common conductors were not stripped well enough in the terminal block of furnace and it was pinched against the insulation. When I fixed this furnace control displayed for heating and system came on. I checked all wiring connections at zone board and furnace. Talked with Joe and ultimately he decided he wants to move forward with estimate I left last time to charge the second floor AC to design. He is still planning on replacing this AC in the near future so wants to hold off on EZ trap and wet switch (water safeties) Charged system 18.5 oz R410A refrigerant to get to design subcooling 10° Was running at 4.2° Subcooling before charging. I also verified zoning was working. Zones dampers are 8x24 damper controlled by thermostat in middle bedroom. And

The AC for this system dates to early 2017 9 years old based on serial number of the outdoor unit. Bryant 3 Tons. Furnace was installed by us in October 2025. Homeowner said for the few days they have needed cooling this year the AC did not work. I tested and system came on. I did lower the fan speed from 400 to 370 CFM per ton 3 Ton. 1st Floor system is 100,00 BTU natural gas furnace with 3 Ton AC gas furnace dates to 2007, AC dates to 2018. Gas furnace is 18 years old.

• replace heat pump transducer under part warranty • test for proper operation of equipment after repair. 2/16/26 Barry installed new pressure transducer using a 1/4” swivel tee and flaring the transducer connection. Used nylon and a seal-tight gasket for flare connection. Afterwards tested for any refrigerant leaks. No leaks. Tested system and checked that new transducer is providing the correct input to the control as regards liquid pressure. Matches within 1 psi Good They said the system has been performing better since we were last here and made adjustments. Left estimate to properly stall and fix the 1/2” electrical whip that feeds Bosch inverter outdoor. Whip is too long and needs a 3/4x1/2” reducing washer. Also left estimate for surge protector for outdoor unit. Also offered plan membership. They agreed. Collected payment for invoice today, System operating well at this time.
We have worked on this Bosch heat pump for previous homeowner. It was overly overcharged by another contractor. I recovered refrigerant, installed new filter drier and charged system factor charge plus what is needed for Lineset. Yesterday the current homeowners called in to us for no heat. They had another contractor tell them the electric heat kit had failed. I found the new heat kit had zero volts at 24V control because of a loose low volt wire. Now 5KW electric heat kit working. Wire feeding heat kit is 6 gauge and the nameplate on heat kit indicated that up to 10KW can be installed. I also landed a wire to the W1 contact of the spacepak control (previously it was wired to heat kit itself only) so it accordingly increases blower speed when there is demand for auxiliary heat. I then went to the outdoor unit. Control was locked out on H5 error code. (5 low pressure incidents in 100 minute period. Reset power to the outdoor unit and put gauges on system. Found that pressure transd
