Entries #198, #199, #200, #201! Just thought that incorporating "G" with "S" for "services" might be good move from branding point of view,...this subtle suggestion of service, in your customer's eyes, gives your company more credibility and feeling of trust! Hope you'll like the idea! Thank you!
...still awake,...had to perfect this design - #221, #222! :) ...there's updated color, more towards green spectrum, and main font is custom made, therefore unique!
I'm guessing you're using copper pipes for heating installations and AC instalation connections, so this copper color on #229, #230 actually might be quite interesting, forming the "S" shaped pipe arround the "G"!? Check it out!
I'm back with few more developments on this logo. On entry #240 you have subtle effects added to create more eye poping design (usualy applicable for some web use, or merketing materials) and on #241 there's negative space version, just to show you how it works as monochromatic version!
Further development on #242, with 3D version on #243, and negative space version on #244. On this version I gave it a bit of technical touch, with copper pipe joints incorporated.
Another design on #245, #246 and monochromatic black on #247.
If you have any ideas for improvement, let me know, and in the mean time maybe I'll try to come up with new concept! Thank you for your cooeration on this design so far,...I think it is going in right direction!
...and there's another approach, with "heating & air conditioning" concept, on entries #252, #253! I've used stronger font to redirect attention from too much letters in tagline. It is also symbolicaly and proportionaly well balanced logo, but I would still recommend concept that is keeping word "services" in the logo (#228, #230),...from branding point of view, visualy it already gives you closer relation to your customers.
Please don't hesitate if you have some suggestions for improvement on any of these! Thanks!
Also, I could try something in direction of a flower/four leaf clover, that you seem to like, but I don't see any symbolic relation of that approach and the work you do!
Here are two variations (#266, #267), with your latest suggestions incorporated,...there are two font options. I usualy don't suggest too much text in the logo, but this looks good and informative, and you can always remove the tagline, depending on logo application, and use version like on entry #228.
There's also new development on my entries #268 and more color accented version on #269. I've just realized you have Irish background (sorry,...I'm a bit slow after the holydays:), so four leaf clover might be interesting, but this kind of symbolism doesn't realy have much to do with the work you do. On these designs, I've tried to incorporate it, but in very subtle way, so it acctualy doesn't "scream" St. Patric's Day party, while it has elements of heating and air conditioning, in form of a fan/four leaf clover!
...just playing a bit more with my 2nd concept. :)
On entries #274, #275, you have basicaly all elements of your work incorporated - initial "G", cooling/heating/air conditioning, fan element more prominent, to suggest air flow, all in form of a flower, that can also be interpreted as four leaf clover, but in very subtle way! Thanks!
...and finaly one more color option with two font choices on entries #276, and #278,...to get better idea about overall proportional appearance, negative space versions on #277 and #279! I believe we've explored almost all options with this design concept, but if you have some ideas for improvement, let me know! Thanks, Chris!
...and in case you still prefer Irish element in your new logo, here's actuall Irish green, but without introducing obvious Irish graphic symbols,...I'm guessing your clients/customers are multinational/multiethnic!? (entries #282 and #284,...negative space versions on #283 and #285). Cheers!
