Instead of having a ton of comments, I'm going to gather all my thoughts on how to improve this mod here. These are all just suggestions and shouldn't be taken as anything more.

• The Item names of the "Red Pipe" and "Blue Pipe" should have the word "Air" added to them to match the "Cyan Air Pipe"
  
• Change cyan pipe to green to better match other temp mods and to avoid confusion with cyan power conduits (green being the color used for ideal room temp)
  
• Make the blue pipe's overlay a darker blue to increase the contrast from the cyan power conduit's overlay
  
• Exposed pipes should have a negative beauty similar to exposed power conduits

• Full Vents and Wall Vents have the same construction cost while having different effects.
  
• Full Vents don't count as load bearing for roofs
  
• Consider ditching full vents and just having wall vents of various size/strength. The wall mounted ones are far cleaner looking and can be placed on both sides of a wall tile. The full vent look is best for objects that affect both sides of the wall like vanilla vents and coolers.
  
• Perhaps a 1x1 at 50cc, a 1x1 at 100cc, and a 1x2 at 300cc
  
• Both vents have an option to toggle power even though they don't use power and the option does nothing
  
• The toggle open/close option of the vanilla vents would be nice. When closed that vent should no longer use flow and would increase flow eff

• Bug: When power is toggled off, the connected vents get locked to the current exhaust temp regardless of intake temp changes. Also the listed Thermal Eff does not decrease
  
• Bug: Info says low power mode when it never seems to change modes. I'm not sure how this should ever be anything other then high mode due to it always either heating or cooling the air to a specific temp
  
• Bug: Currently you can set different temps for different controllers on the same network. This causes the whole network to act all wonky. The temp setting should really be saved on the pipe network or some other way of preventing this behaviour, though I can foresee this being problematic to solve due to the possibility of merging 2 separate networks.
  
• Bug: The Large Controller is currentlky handling 3500 cc of air instead of 4500 cc. If the large is to be handling 5x the small and be in line with 3 large intakes, then they should get bumped up to 4500.
  
• Small and Large have the same construction cost while having different effects.
  
• Both obstruct walking and space, which can obstruct air flow. Would be better if they didn't
  
• Would benefit from having the same "choose your pipe logic" as the vents and the ability to build pipes and climate controllers on the same tile. Not terribly useful, but consistency is nice.
  
• The reinstall option is not auto flagging the machines to be uninstalled, so the reinstall never happens. The Industrial Rollers mod has the same issue btw.
  
• The large controllers don't rotate correctly. The heat exhaust rotates in the correct direction but the art rotates incorrectly. Should just need to swap the left and right art.
  
• All machines like this should have a negative beauty

• Neither Small or Large have components in the construction cost but they are flagged for component breakdown. Their construction costs really should require a few components
  
• Both obstruct walking and space, which can obstruct air flow. Would be better if they didn't
  
• Would benefit from having the same "choose your pipe logic" as the vents and the ability to build pipes and Intakes on the same tile. Not terribly useful, but consistency is nice.
  
• The reinstall option is not auto flagging the machines to be uninstalled, so the reinstall never happens
  
• Consider requiring the intakes be either outside or unroofed as to prevent cheaty loopholes.
  
• Alternatively, give the intakes a local exhaust equal to the cc they suck in and the temp of the current outdoor temp. So a normal intake that takes in 300 cc would push 300cc of outside air into the area it is placed. This outside air can be viewed as the air that needs to leak in to replaced the sucked out air.
  
• The large intake's art rotates incorrectly, same as large climate controller
  
• All machines like this should have a negative beauty

If you have a small network you can get a single large room to ideal temp very easily. Then if you fill that room with large intakes for a second network,you can spread that air to every room of a large base without needing climate controllers on the second network.
If the first network is 3x intakes for 900cc, 3x controllers, and 900cc worth of exhaust, you can have 300% Thermal Eff in the room with backups for breakdowns to easily keep that room at the correct temp. As long as that room stays stable, no controllers will be needed on the second network.

You can also skip that first network and use vanilla coolers and heaters to get a room to the correct temp then just fill that room with intakes. This way you can skip the climate controllers all together.

• Consider moving all the objects into a new section of the architect menu, more so if more objects get added. An Air Conditioning section would prevent the Temperature section from getting too cluttered.
  
• Moving the network's temperature setting off of the Climate Controllers and into a network popup. This could allow for setting an ideal temp range instead of just a fixed point. This popup would be accessible from any of the objects that make up a network and would give a full overview of how the network is functioning.
  
• Spreading the objects out over multiple research techs. The current tech is a bit loaded atm and tiering out this mod over a couple of techs might make sense.
  
• Consider having 2 separate machines for heating and cooling on an early tier instead of the all in one. Later tiers can have the all-in-ones that can be more efficient if you need both but less so if you only need one. ie: who needs a cooler on an ice sheet; who cares about a freezer getting too cold
  
• Consider possible ways to have a first tier that doesn't require power. A wood burning heater is easy, but perhaps a weak cooler and an intake that uses wind speed to capture variable amounts of weak intake.
  
• Consider an advanced smart vent that auto opens/closes when the air in the pipe is between the temp of the room and the desired temp of the network. This way we can maximize flow eff without having massive amounts of intakes
  
• Consider having toxic fallout get sucked in and spread toxic buildup to pawns indoors via the system. Which would require adding Toxin Scrubbers to the network to clean the air. Since toxic fallout is a rare event, the scrubbers should be expensive in some way to discourage users from building them before being needed, perhaps gold on construction cost or use a ton of power.
