Metro HVAC · From the field
Dillsburg, PennsylvaniaNo heat.
No cooling.
Time to find out why.
A Daikin ductless heat pump had stopped providing heating and cooling. The Metro HVAC team found improperly made refrigerant flare connections—and got to work correcting them.
The homeowner’s problem
A system that wasn’t heating or cooling.
When a heat pump stops doing both jobs, identifying the cause comes first. Metro HVAC visited this Dillsburg home to diagnose the system and determine what needed repair.
What Metro found
Flare connections that needed correction.
Flare connections join refrigerant tubing to components of a ductless system. On this Daikin unit, they had not been made correctly and needed to be redone.
The repair, step by step
Small details. Careful service.
Our work covered the refrigerant connections, the indoor heads, and the steps needed to prepare the circuit for an accurately measured recharge.
Recover
Refrigerant recovered
We recovered the refrigerant before opening the refrigerant circuit.
Repair
Flare connections remade
Our technicians remade the faulty flares to address the connection issue found during diagnosis.
Clean
Every indoor head cleaned
We cleaned all of the indoor mini-split heads as part of the service.
Test
Nitrogen pressure test
After redoing the flares, we performed a nitrogen pressure test to check the refrigerant circuit for leaks.
Evacuate
Vacuum down to 200 microns
We evacuated the system before adding refrigerant. Evacuation removes air and moisture from the refrigerant circuit.
Charge
Factory charge weighed in
We recharged this system with its specified factory refrigerant charge of 6 pounds, 7 ounces.
Specific to this repair: The 200-micron reading and 6 lb 7 oz charge describe this job. Charging requirements depend on the equipment and installation; a vacuum reading alone does not replace leak testing or the other service steps.
Why the details matter
Address the cause behind the symptoms.
This Dillsburg project involved correcting the faulty flares, cleaning the indoor heads, performing a nitrogen test, evacuating the refrigerant circuit, and measuring the charge.
If your ductless heat pump isn’t heating or cooling, a diagnosis can help determine what needs attention. Similar symptoms can have different causes, so the repair should follow the findings on your equipment.
