Farmer with HVAC knowledge?

[Shadow_storm56]

I'm sure some of you fellow farmers have dealt with many types of hvac units, especially thoes with rental properties... anyone ever run into the issue with a heat pump (specifically daikin) having a board failure and will always ramp down to idle a few mins after starting and just stay at idle..... nomatter what you do the compressor just idles... 5-10% power. Cost of the board is 50% that of the unit so if they don't warranty it it's garbage. Anyone here ran into an issue like this on a heat pump? Maybe theres a clever fix?

My condolences. . . unless there is a universal board like the ones used for the indoor air handlers or gas modules I think you are screwed. A friend had a problem with a Goodman unit a few years ago - same type of issue. - board was proprietary and price was unbelievable. He ended up replacing the entire unit.

I never heard of Daiken so did a google search for reviews, good luck!

   The units in our village hall use 2 – 3Kw per day in standby mode while the hall has not been in use. This mounts up in the running costs and was obviously not a good option for this type of location. The overall costs including servicing are significantly higher than we were spending using electric heaters.

   The top Daikin dealer in Canada sold me a Daikin 3MX 39,000 BTU 2 head Multi Zone last year. They offered a 12 year warranty on all parts, labor, and compressor. They stated a “no charge for service calls for 12 years.” They have ceased operation in Newfoundland. HotFrost who is taking over for Ecoheat verified that I do have a 10 year labour and a 12 year parts warranty on your unit. However, they say the warranty does not cover diagnostic service calls, which are $189 plus tax. This Ecoheat company is still selling Daikin products in other parts of Canada, and are listed on the Daikin website. How can this fake company still be associated with Daikin. Or, how can Daikin still be associated with this fake company?

     Most reviews are negative if you sift through all our comments in the reviews category. People don’t think about their HVAC systems until they fail or have issues with the systems. And then they become emotional and want to vent.
     Another reason is some people always go with the lowest bidder rather than vet the contractors installing the systems. They typically end up with Joe Smoe who does a quick and lousy job and that results in poor performance and reliability issues.
     You buy a car but if it wasn’t assembled properly then it will likely fail you. It’s very important to select a competent contractor who knows what they are doing. This site has several articles and references on why that is important. We always advise choosing the contractor over the brand. A good contractor will do the job right and back up their products.

       or the supplier has no income servicing the warranty other than what the manufacturing is offering

     The product may not be garbage, but some of the dealers certainly are.
     Daikin doesn’t care who or how their products are sold, as long as they are sold.
     Terrible customer service.

     That is because they are junk.
     I have owned over 200 single family homes, duplexes, and Multi family. I have installed and observed operation of just about every brand and type of HVAC that is out there.
     The High End Daikin 5 ton variable speed Heat Pump (and VERY expensive) is BY FAR the biggest piece of junk we have ever had installed. It has not functioned properly for more than about 2 weeks at a time. Techs have been to home 16 times since install. We are finally getting a new unit (NOT Daikin) to be installed this week. FYI – also SUPER inefficient. Power bill has about doubled since install of this unit.

   we have air source heat system, it worked fine for 12 months, then firm went bust that installed it and low and behold, no warranty, a recommended service engineer came out, blew through condensate pipe, said that would cure it, 2 months, back to square one. I am beginning to think I have been stitched up with the Friday night rubbish. Will never have Daikin again, the warranty for the units belongs to the installers when they buy in bulk. I hope Car manufacturers don’t operate the same. manufacturer warranty should be the warranty not “tough luck if your installer goes bust”

   Agree with the comments above. We have had nothing but issues with our 5 year old system. Worked for about 2 years then has not really ever worked since. Few HVAC specialists can even diagnose issues on these systems let alone actually fix them. After $3K of trying to fix our $15K system we decided to cut our losses and get a ‘less efficient’ system unit that actually works.

   Works great . Sounds very quiet compared to neighbors.
   Great warranties. Residential furnace and air conditioner system.

   Have my new Daikin heat pump and furnace for 2 months now and working good so far. The Daikin CTK04 thermostat control is not as described in the manual. Be aware that Daikin customer support will not talk to residential homeowners. They will only refer the homeowner to the installer or so-called licensed Daikin dealer. Even a simple question like why the owners manual does not match the display on the thermostat screen will not be answered by Daikin Tech Support.

   I have a high end Daikin ducted mini-split system. Great in concept and works great when it has not leaked out all of its refrigerant. The system in its 10th year of operation has gone through the four original coils and 6 replacements. It now needs two more replacement coils. The develop leaks at the drop of a hat. I’ve been given all kinds of excuses but no accountability to help fix the underlying cause. Daikin has known about corrosion and copper coil leaks for some time. I will NOT allow Daikin products to be used in any of my projects going forward nor would I buy a property with a Daikin System until this inherent defect is resolved. Just replacing like in kind coils is expensive and not the solution. A real solution backed up with a warranty that it has really been resolved would be start to restore confidence in your brand. I can’t afford to buy or build properties with equipment from a manufacture that can’t provide cost effective reliable equipment and help you resolve problems when they occur, especially when they are on the manufactures end. You have lost one of your best advocates/customers’s for this type of system…not only for my residence but for any commercial property I’m associated with….looking elsewhere

I have seen the Daikin heat pumps here and there installed on houses and businesses . But didn't buy that brand as Mitsubishi had the lowest operating temperature for the north woods here.
I have four wall head units. The only issue was one head unit from the factory didn't work properly. The tech did a phone call with Mitsubishi trouble shooting and found a circuit board was not working. A new one arrived fedex the next day and the tech replaced it and no issues in three years.
The heat pumps are Not the best heat source in cold weather but in the hot as hell humid summer weather we've had. They haven't shut off in three weeks. What a life saver. I love them for the AC.

I work for a global HVAC manufacturer. On the inside, we always say buy the longest warranty you can on a fancy unit or buy the base model. It is likely that the compressor VSD board (essentially a board that modifies line power and spits it back out to control compressor speed) is "proprietary" . While they are not truly proprietary, no one else makes them because there is not enough money in it.
The sad truth is you are not in a unique predicament.

Everything is such trash these days.... humanity has to figure a better model than building stuff as trash so that it breaks and another unit can be sold so that the business continues to exsist

I wish I understood the circuits well enough to fix the parts that are damaged on the board.... and find them

The basic 'operation' of HVAC is rather simple ,the real problem is 'computers' are so dang cheap, that 'engineers' cut all kinds of 'code' for 'fancy' functions and looks that ,in the end do NOTHING for the safe,reliable operation of the equipment. Then after the design, the 'bean counters' take their 'kick at the cat' to reduce the cost by trimming 'this and that' with the end result a low grade product with a very limited lifespan.
My AC is a Clare unit, 36 years old, 2 ton, still works GREAT. ONLY reason I got rid of the 96.5% furnace(36 years old...) for a 94% one, was to get a deal on insurance.
As for the 'computer' control board. Yes ,propriatory but nothing that a $2 PIC,20$ worth of SSRs, and 100-120 lines of 'code' can't replace. BTDT back in '87, even had ultra high secure, hacker proof remote control via phone lines.

Today, a neighbour's RedLion brand shallow well pump died, it's maybe 3-4 years old ( you can eat of it it's that CLEAN !). $400 pump needs a 50 cent spring for the centrifugal switch. Red Lion can't supply the part, can't fix it, says gotta by a new one !

The reason is not so the business continues to exist. It is driven by the consumer. We want all these fancy bells and whistles so they all try and outdo each other to get us a widget that has them. The manufacturer calls up a board supplier and says "hey, we need 300,000 boards a year. What's your lowest price". If they said "we need your best, most reliable board" they would cease to exist. Because nobody is going to buy a $80,000 AC unit for their house. Especially when another brand will do it for $8,000.
Same thing with cars and all the gadgets in them these days.
