I have a metal building that I want to use for my reptiles. And we had them in the house but we had some people working on there room in the house so I moved everyone into the building two days ago so the room can be finished and I have to tell you I really enjoy having the extra space in the house and the building is so much larger and easier to move around in and clean everyone. BUt the building does not have heat or air. It is completly wired and there flexwatt and radiant heat panels are hooked up with thermostats and everything But I was going to wait until the beginning of next year to try to make the building suitable for the animals but now since Ive actually gotten them in there and everything I would really like to get the ball going and get them in there permanent. Now I have some people coming out tomorrow to give me a quote on a central heating and air system. But I was wondering if that was my only option or if there were other options? Id really like the building to stay around 80-85 degrees all year round and I really dont want it to get any cooler then 75 and im trying to not get any higer then 93. Its not to hot in there now and everyone seems comfortable but eventually it will start getting to hot in there I believe and once the winter hits im sure it will get pretty cold in it considering its a metal building. It is insulated and I have heaters I can put in there to heat it up but there are no windows or anything to add ac to cool it down if it gets to hot and I was wondering if anyone else has converted a building to a reptile house and what direction they went and how they like it. Thanks for all the help here are some pics of the building to give you an idea about how big it is and how much there is to heat and cool thanks!
