I'm looking to replace 2 x 3.5Kw and 1 x 7Kw wall mounting A/C units next spring. Can anyone recommend a reliable company in the Girne area please?

There may well be a new company supplying Inverter air con units by next spring , inverter air con units Consume up to 30% to 40% less energy than non-inverter units , prices will be approx 30% less than other air con companies in the TRNC for 12000 and 18000 BTU systems .

Trouble is, in uninsulated houses the benefits of inverter A/C is negligible..and the extra cost is not...

Time for some one to start selling insulation

Or build Houses/Villas properly .. Retro fitting insulation is about as expensive as it gets.. One day they will learn..

But if you can re-new old air con units for inverter units at the same price as what companies here sell non inverter systems for , surely then it would be worth doing !

Inverter Units are only more efficient in a "Sealed" thermal environment..If the House is not insulated they are fighting an uphill battle .Insulation is the major factor in thermal efficiency...Most houses/Villas here because of the construction methods suffer "Heat Sink" similar to storage heating,so without insulation it's a waste of time and more importantly Money...

Inverter units are only efficient if they can control the "sealed" environment. If a house is not insulated they are fighting an uphill battle.And with mid summer temps in the high 30/40s they will not prove efficient.Insulation is the "Major" key to thermal efficiency..

martin-msg 8/9

would that same principle not apply to every sort of aircon, or heating for that matter?

Inverter would therefore be more efficient in a non efficient house,than non inverter in an non efficient house?

I accept what you say about the thermal qualities of property here, and from your previous posts you are a big fan of the british standard cavity wall set up.

But an igloo works great in greenland, not so good anywhere else.

Mud Hut works great in africa-not good in rainy england.

I used to own a house in the rocky mountains in canada.

It was made of wood with a high level of insulation-the temperature went down to -45 on occasion,but the house was always warm and snug, with high insulation values and lower heat loss than I had ever experienced from my uk cavity wall home.

However, if you built that same house in the UK, I imagine it would rot in about 5 years.

my point is, homes tend to be built according to local conditions,

philUK"homes here tend to be built according to local conditions"



So you are saying that uninsulated thermally inefficient solid wall construction ,where the temperatures range is probably 35 c or more ,is the way to go ?

martinD41, like several other posters on here, I am sure you are trying to use your knowledge and experience to be helpful to the members however, also like several other members you are skirting around the facts in the post to make sure people understand your point which in this case is unfortunately a moot point.

Everything you are saying is absolutely correct however it is completely redundant due to the fact that houses are in fact built the wrong way and this is not the UK, therefore when someone is looking for air conditioning and another member is taking the opportunity to talk about soon to be available systems that are more economic within the restrictions of North Cyprus, it is hardly helpful for either the buyer or seller to be told it doesn't work as well as it could or should in the right situation.

I would seek your advice when I wish to build a house from scratch but your advice here is like saying, don't bother, there is no point. Not really helpful IMHO

Thanks for your input, But in order to compensate for the lack of thermal efficiency ( in TRNC Homes), I am told by a well known installer that units are OVER SIZED......thus nullifying the advantage..

martin, how is getting a more economic system than the existing type nullifying the advantage. People would like to have air conditioning hence post 1 asking for air conditioning, your basic saying there is no point because the houses are built badly and the only units that would achieve anything are over sized, so what is your answer, the poster still wants air conditioning and another poster has advised them about a soon to be available more efficient system, that is being helpful, you are just being disruptive because you want people to know that the houses here are not built well and you need to get bigger units.

I know people might think I am being argumentative but all I am trying to point out is that the poster asked for AC unit suppliers, a member offered constructive comments about a more economic system than the existing available system and all you have done is slagged of the buildings and not helped anyone, why even bother.

To make things simple . Last year we had an 18000BTU non inverter air con unit in my office and storage room ,it cost us around 9TL a day to run.



This year we added a 18000BTU inverter and it is now working out around 5.9 to 6.1TL per day .



That is the same office storage with no thermal efficiency and 22ft high ceilings.



So in our calculations in this test thermal efficiency means nothing with regard to inverter air con , we are still making a saving without thermal efficiency .And with our office door open David is happy chappy

msg 1,



I am and have been fitting inverter a/c units for some time now and these will be on offer next month.



msg 13



a/c units usually ,come in standard sizes of 7000 Btu*, 9000 Btu, 12000 Btu, 18000 Btu and 24000 Btu

* not usually available in TRNC.



On sizing a room and calculating the duty of the a/c, if the calculation falls between 2 sizes, it is wise to go up a size rather than down. This assures that the required temps are achieved and that inverters can slow the unit down and achieve savings. Going down a size means that the inverter may run flat out continuously without even achieving required temp and thereby negating any possible savings.

The extra cost of an over-sized unit will still be returned in the payback although it may take somewhat longer.

An article in Wednesdays Cyprus Today, suggested that the price charged for a unit of basic tariff electricity would rise to 55 kurus.

It has always been know that the price would never drop, but if this doesn't make the case for inverter a/c, I don't know what does. Such a rise of about 30% will reduce payback time accordingly.

I had an inverter air con fitted by argos are us . It runs so silent you can'nt tell its on, its a grundig

so we can expect it to be very reliable .i went in at 3pm they explaind all the pro's and cons i ask about

payment they said pay us when you are happy .It was fitted at 9am nexted morning.

Its been operating for two weeks and i am very happy.
