Guess it depends if he wants to risk them saying they'll be back tomorrow when its thawed.

A pic of the frozen suction line will prove it was frozen.

Take some pictures, then thaw it out in advance of the tech's visit.

I took pictures of outside ice build up. Turned the fan to ON but have no airflow at registers....guess evap coil is completely iced up. I can hear the fan running but no flow. Will attempt to attach picture.

EVAP coil install questions


After waiting 3+ hours for original install guy to get to my house he says "his" evaporation coil is not leaking...there is a leak somewhere else..he did put in 7-9lbs of refrigerant yesterday but no more tonight. He said it's real low. I asked the installer how he measured 7-9 lbs...with no scale. He says its all on the gauge. Is this for real? I thought a scale was used for weight - not pressure. Please educate me!!

Repair supervisor called me to let me know another tech will be out tomorrow to locate other leak and then supe will discuss additional cost. WTF!!!

I'm already hot and now I'm steaming pissed at the ineptitude of this company.

More questions:
Should I be responsible for additional cost because original diagnosis was incorrect/incomplete?

Is the "Company" responsible for additional cost since they screwed up the diagnosis?

Thank...

The gauges can NOT tell anyone how much they put in. Only what the saturation pressure and temp is. They have no ability to weigh the refrigerant as it goes through them. He gave you a line.

EVAP coil install questions


unit can be low on charge and cause freezing (probaly is low the leak they said was at the indoor coil did not exist). But it can't be real low and freeze. If a unit is extreemly low won't cool but won't freeze. extreemly low charge unit won't even approach freezing temps. Almost every unit i see frozen are 1 to 2 lbs low on charge. this is still unaceptable

Agree about the gauges - refrigerant gauges do NOT tell you how much refrigerant was put into the system. They are lying to you, are inept, or both.

When they come to find the leak make them show you where the leak is. The should be able to pinpoint the leak and show you with bubble soap exactly where it is. If they can't do that, then it is almost certain that they undercharged the system at startup, and you should be charged nothing additional.

You're not sure whether the original diagnosis WAS inaccurate. The coil could have been leaking, in other words.

The only thing you know at this point is that the system doesn't work, and that it's apparently low on refrigerant. If so, then either (a) they didn't charge it correctly or (b) the leak they found was not the only leak in the system or (c) they're inept or (d) all of the above.

Given what you've reported on this job, my money is on (d)

As to who is responsible - the warranty company will treat each new "issue" as a separate claim. So if the evap coil is leaking, that is a single claim. If the condenser is later found to be leaking, that's considered a new claim, and you'd be responsible for a new deductible and all the other non-covered charges. IMO that's not right in this case, but as I said earlier, you're dealing with an insurance company.

Finally: At some point I sincerely hope homeowners wake up to the fact that the home warranty services are a scam. They paint a very pretty picture, but they have so much fine print that you never know what you're actually getting. They deal with bottom feeding contractors, except when they're forced to use others, and they always - and I mean always - go for the cheapest contractor in town. They'll tell you that they use many factors to determine which contractors are given the majority of their incoming calls, but it's all about money - the contractor who charges the lowest per-call cost is the one at the top of the list, even if they are completely and totally inept.

I know - a year or so back when I was doing a fair amount of work with the home warranty companies, all I did was do second opinion work for them (i.e. calls where the first company had screwed up, or refused to return to the job, couldn't fix the issue, etc etc). One company in our area was notorious for poor workmanship, missed appointments, failing to complete jobs, etc etc - had several judgements against them, had lost their license at one point (but hired another person with a license to keep on scamming customers) ... in other words, your worst nightmare in terms of HVAC contractors.

Guess who was at the TOP of the warranty companies call list (hint: it wasn't me). The ONLY thing that caused the warranty company to disassociate themselves with that HVAC company was a lawsuit filed by a consumer against both the HVAC company and the warranty company. Otherwise, I can almost guarantee that they would still be using the HVAC company

EVAP coil install questions


Last Update (I hope!)
Third tech visited a few minutes ago. Went through entire system and found.......a leaking schrader valve. He spent more time charging and monitoring the system then the others combined. Used a clamp-on temp reader on the low pressure line next to the compressor and really took the time to get the system running right. This guy knew what to do.

It's down to 75 so far and no ice build up...fingers crossed it can get to 73 tonight.

Thanks for everyone's input. I gained a lot of knowledge and respect for you guys in the field.
