Thanks all of this is helpful - still trying to get a picture of what the setup will be and what extra costs they are going to try to push and what I can avoid.
There was something listed "X1 TV box separate" - I have no idea what an X1 is - of course we do not want their DVR or modem - I assume we can refuse it? (
plan we are considering)
X1 refers to Comcast's proprietary user experience system. For more information see
here. The X1 TV box (whether DVR or headless client) is a digital set-top box that you would rent from Comcast. The typical monthly charge is $5.00 per box, but it could be higher on some older billing systems. And, depending on your service package, the physical DVR (in addition to basic cloud DVR service) could add another $10.00 fee. Again, much depends on which type of package you subscribe to and where you are located since offers and pricing will vary throughout Comcast's retail footprint (although they are moving to standardize their entire system under the rubric "Simple & Easy").
Note that your link above will not show us the specific plan you are considering unless we happen to be located in the same service area as you. However, I have looked at the plans currently being offered in Manteca, CA (zip 95336), and I see X1 Saver Pro+ Double Play as well as X1 Starter Pro+ Double Play, among others. Is one of these what you are looking at?
If X1 is a cable box - we kind of already have a 6 tuner box with Tivo - so any cable box - no X1 should be required? Someone already said no tuning adapter - so it's cable in from wall straight to the Tivo?
All of the above is correct. You do not have to accept either the cable box or gateway (modem + router) rental from Comcast. But you will require a Comcast multistream CableCARD, which should be provided to you free of charge upon request. You will also be entitled to a $5.00 (previously $2.50) customer-owned equipment (COE) credit.
I've already bought a modem (SB8200) to stop that rental.
That model, which is DOCSIS 3.1 compatible, should serve your purpose for any Comcast HSI service tier up to 1Gigabit. Once you have established a Comcast account, you can check any retail model's compatibility with your Comcast service (which will depend on your speed tier)
here. To save you some trouble I am attaching the compatibility info on the Arris SB8200 below:
Note that the SB8200 is not VoIP-capable. If you were considering getting this service from Comcast you would need to look for a different modem. And, of course, you will require a separate router to pair with the modem. Most of Comcast's current rental gateways (models XB3/6/7) consist of a combined modem and router as well as a MoCA adapter, all in one unit for a monthly fee of $14 (plus tax).
Another cost - From their site -
30-Day Money-Back Guarantee applies to one month's recurring service and standard installation charges up to $500 -
Well $500 is insane.
I've never once ever paid anything to get cable TV installed and running in a new house so this is all news to me. If there were any other choice I'd pass on paying for the privilege of allowing them to sink their hooks in and bill us monthly for many years to come.
That blurb is simply saying that they will limit their refund guarantee to not more than $500.
You should be able to avoid any installation charges by electing a free self-install kit; otherwise, I believe installation service by a technician will run you $90.00 depending on which service bundle you select (some deals include free professional installation).
In terms of "extra costs" (above and beyond the monthly service charge for TV and HSI, you should be looking at a total somewhere between $25 and $35 aside from any rental fees or VoIP-related fees. This includes (specific to your location) a $13.90 Broadcast TV Fee, a $8.00 Regional Sports Fee, and assorted regulatory fees and taxes.
I recently helped my sister to set up her Comcast service in nearby Livermore, CA. She opted for the X1 Premier Pro Triple Play with HBO bundle plus Xfinity Mobile cellular service, which I assume is more than you need or want. But much of her experience is applicable to what you will be dealing with, so feel free to continue to post your questions and we will attempt to address them.
