An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this Comcast phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like Comcast staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy time to call

The least busy day to call Comcast is Thursday. The most busy day to call is Tuesday. Again, this is based on a sample of 55,193 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold

We measured the shortest hold times to be on Wednesday. The longest wait in the queue on average occurs on Monday.

The best time to call

In summation, the best day to call Comcast is Thursday. This is not the day with the shortest wait on hold in the phone system, but we still recommend it for its ideal combination of low call volume and short hold times. Plus we believe that Comcast staffs the call center well on Thursday.

I'm in the process of opening a new small bakery in the Brighton area right outside of Boston, and one of the tasks I need to take care of for my business address is the internet and phone service. Anyone from the area knows that Comcast is the logical choice if you want to go with a provider that has a big reach and plenty of options. Before setting up my service, I had to talk to an agent because this was my first time buying anything as a business and I wanted to make sure my needs were met. 

Given this was the Comcast business side of the company, I imagine that they get a ton of phone calls daily for customer support and troubleshooting issues. While no one likes downtime, a business can't sustain any type of downtime when it comes to internet or phone lines. Therefore, I was prepared to wait a bit, but to my surprise, it only took about 2.5 minutes to talk to someone and figure out what would work best for my business. I know people complain about Comcast, but honestly, it's hard to beat their great customer service. 

When I first called, an automated voice picked up the phone and said, "Thank you for calling Comcast Business. This call may be monitored or recorded. Enter or say the zip code where you have or want service." I entered my zip code which the system said it didn't recognize, which wasn't a surprise to me since I wasn't a customer yet. It had no reason to recognize the line I was calling from or the zip code I put in because I don't live in Brighton myself. That's just where my business is. 

The voice assistant told me, "Sorry, I didn’t find an account based on your zip code. I’ll need an account number or a phone number to look you up, or if you're calling for a new account, say a new customer." I repeated new customer as instructed, and it reaffirmed that the call was for setting up service for a business which I confirmed.

There was a brief pause for about 20 seconds with nothing happening, and I thought for a second that maybe I was disconnected. While I was trying to figure out what was going on, Ray picked up the phone and asked what he could help me with. He made the sign-up service easy and was polite and clear about all aspects of the contract. Plus, it only took me about 2 minutes to get to him, so it was worth my time for sure. 

Jeff truly believes that all customers deserve good service. He’s been building tools, inventing phone tree hacks and helping customers since before his days at GetHuman. He's also a Google GDE and involved in the Angular community.
