Without experience, it is possible to successfully GC a bathroom remodel; however one has to do sufficient research and acquaint oneself of all the stesp in the remodel. It is not rocket science, however, it is a complex project and cannot be under-estimated. If you are not changing any plumbing or electrical wiring, keeping the bath layout essentially the same and only changing the skins, (e.g. faucets, tiles, tubs, etc.) it is not very hard to do. Also, if going as self-GC, try to keep some allowance for change orders, since due to lack of experience, you might make a few judgement mistakes. We are currently our bath remodel in a semi-GC fashion(semi-gc because our main guy is a jack of all trades and knows a lot about it, thus we do not need to constantly micro-manage him). We designed it entirely, I researched extensively using GW forums. Since I always knew what I wanted, look-wise, I used the forum's expertise to learn the technicalities and materials, and for hearing the experiences of the folks here with various parts/materials that we used. Also, we visited local bath remodel stores. We tried to talk to the people in the stores extensively, asked them gazillion questions. When they said "your contractor would know that", I always replied, "of course he might; however as a homeowner I want to learn about the process too". Some were clearly not interested in talking, in which case I moved on and talked to their competitor. For each type of vendor (e.g window company, mirror etc) there would be at least one of three who would be willing to educate you, and the one who left me wiser got my business (at times even though their quote was not the lowest, but within a ballpark). Besides, people who were genuinely helpful were not necessarily the most expensive. It needs a tremendous amount of time invested, patience and inclination to learn, however. You need to ask yourself whether you are interested in learning even a little, OR are you in it only to save money. If the latter, then chances are that you would end up feeling exhausted. For me, I was really passionate about learning the ropes, and I am VERY happy by the experience. I emerged much more knowledgeable and cannot wait to do my next remodel! Hope this long reply helps you.

Good luck finding a reputable contractor. We've lived in the same house for 26 years and in that time we've done many projects - new roof, new siding, a 1000 sq. addition, finished the basement, remodeled 3 bathrooms, added a screened in porch,installed a mahogany deck, a swimming pool, replaced brick walk with custom cut bluestone, remodeled the kitchen twice and had major landscaping done 3 times. We probably worked with 12 different general contractors and unfortunately only 2 of them would I ever work with again or refer to others. Even though we went through all the recommended steps in selecting our contractor calamities still happened - may of them directly caused by the GC trying to save time, money or appease one of his subs or another customer. You don't need to hear my horror stories I'm sure you've heard many. If you have the knowledge, the time and the fortitude to be your own GC then go for it. Just make sure you have all the insurance you need and an attorney to review all contracts. The last contractor we worked with was highly recommended by many people that I knew personally and whose work I had inspected. But he lost his foreman to an injury one week after my kitchen was demolished and everything went downhill rapidly after that. So even if you do everything right - there's still a good chance that things will go wrong.

I say go for it. There are a lot of nay sayers out there but if you do some research about "owner builders" you will find many people do this all the time with great success. You will have headaches, you will have stress, but its a trade off. There are plenty of good reliable subs out there that are willing to do the work. You will just need to research them. Best thing to do is have a written contract for the work. Will GC's get better pricing. Sure. Then they mark it up and you end up paying more than you may have paid yourself. I did a full gut remodel a couple years ago and found a great set of people I will continue to work with. Are they the cheapest? Probably not (plumber is for sure) but I felt the prices were reasonable and I got good work out of them. Go by word of mouth. Get on Nextdoor (the app) and ask your neighbors for recommendations on contractors. If you have time to do research and understand the basics, you can do a lot. If I can rewire my house by learning off youtube and pass a city inspection, anyone can.

I agree, talk to a good HVAC contractor. Finding the good ones is the key point. I'd question if what you are asking for makes sense for your house (how new and how tightly, or not. is your home sealed). Do you want unheated/unconditioned air coming directly into your kitchen, do you want to stand under that supply of air when it is 32 degrees outside? Qualifier: I'm not familiar with Fantech products. What is used in newer, well sealed homes are devices knows as HRV or ERV (Heat Recovery Ventilators or Energy Recovery Ventilators). What these devices do is get any heat from air being exhausted from the structure (cooking, bathroom exhaust, clothes dryer exhausts, etc.), and exchange the heat to add it to air coming into the structure (some do exchange of moisture along with heat). In some areas, northern and colder climates and Canada, these devices are required by code. If your structure is older and enough makeup air comes in through door and windows seals, mail slots, screen doors, garage entrances, dryer and bathroom exhausts when not in use, etc., etc. then you don't want this arrangement. A good HVAC contractor will have someone on staff who understands all this stuff and can tell you what options make sense for your house.
