Oct 6, P&K Heating and Cooling installed four Daikin CTXS12HVJU Ductless Wall Mounted Heat Pump Air Handlers and an outdoor condenser.

Oct 7, I called P&K because the units were not working. They thought the condenser was too close to the house, so they moved it.

Oct 8, I called P&K because the units were not working. P&K determined that we had a freon leak. They came out twice in October for this. They replaced the freon and they replaced a gasket.


I later found out that all units are factory
charged. If a unit is leaking or low, the refrigerant
has to be reclaimed. P&K just threw a tank on it
and started throwing freon in it. It really should
have been taken back to scratch. Even if the
freon leak is fixed, the charge is off, and it will
affect how the unit works.


Nov 7, I called P&K because the units were not working. P&K determined that the location of the remote was the problem. They showed us how to use the remote. They also showed us where to place the remote to better monitor the temperature.

Nov-Dec, I called P&K a few times–the thermostat was set to as high as 85 degrees but the rooms did not feel warm. P&K assured me, over the phone, that the Daikin units that we purchased had enough BTUs to heat the space. They did not come out to personally assess the problem.


Jan 2016, the outdoor temperatures dropped and our Daikin units, purchased and installed by P&K, could not keep up. We had to use space heaters to keep warm. I called P&K at least 15 times to let them know that our units were not working and to please come to fix. P&K did not answer my calls or respond to voicemail.

I later found out that the flare fittings were
improperly flared. Each fitting needed to be
checked to make sure it wasn’t over-flared. In
our case, the fittings were raw, rough, and
jagged rather than smooth. Because of this,
freon leaks were guaranteed. Our units never
had a chance to work properly.


Feb18, I called Daikin Consumer Relations to see how they might help. The Daikin representative told me that Daikin works directly with their distributors. She told me that P&K should have contacted them immediately regarding the problems they were having. P&K never contacted them; if they had, something would have been done by now. She very clearly stated that P&K needed to get the regional technical rep involved. Via email, I offered this information to P&K. They never contacted Daikin; they never responded to my email. My suspicion is that they did not purchase our units from a Daikin distributor, but from Amazon? Ebay? Perhaps this is the reason why they didn’t call Daikin for support—because they couldn’t.

May 12, I contacted another heating and cooling company to assess our system. Here’s what they found starting from bad to worse:

1. One wall unit was tilted the wrong way, and it was loose. The unit was mounted into the drywall, not a stud.

2. The flare fittings were rough rather than smooth. This caused freon leaks.

3. In the outdoor condenser, a fitting, the reducer, was missing a copper ring, a gasket. The seal is the gasket. It compresses the copper—the copper makes the fitting tight. On page 6 of the Daikin manual, it says “Be sure to attach the gasket.” The condenser was guaranteed to leak at some point.

4. The thousands of dollars we paid P&K went up in smoke with this last finding: neon green oil in the lines. This is the sign of a dye. First of all, the use of dye to find a leak is “old-school”. These days, 90% of heating/cooling companies use sniffers. In our case, the green dye contains a special kind of oil which doesn’t match up with the oil used in Daikin units. Daikin fears cross contamination and prohibits its use. (In order to risk cross contamination with oils used on other non-Diakin units that a service shop might deal with, Daikin requires that their authorized service dealers use a special set of gauges for use on their systems only. That’s how cautious they are about cross-contamination.)

We were presented with 2 options:

1. Flush the lines with nitrogen to remove the green oil that might have migrated into the condenser coil—but there was no guarantee that it hadn’t already migrated into the condenser coil or that they had removed all the dye. We could fire everything up and hope for the best, knowing that it could possibly be that 6 months or a year later, valves could start to stick or the compressor could go out. Because the oil is new to this system, there’s no
precedent of what might happen when a foreign dye is injected. The use of the foreign dye voided the warranty that was in place.

2. Rip out all the lines, rip all the units from the walls, and redo everything. We really had no choice other than to go with Option 2. All the lines, wall units and compressor were replaced. The good news is that the heating and cooling company that we used had the full support of the Daikin technical reps. They used all the right Daikin tools. They knew what they were doing because they were also Daikin-trained. It makes such a big difference to deal with professionals who know their business! I have not had a single problem with my new heating/cooling system!
