Find the Cheapest Natural Gas Rates for Mount Prospect IL 60056

Constellation lowered my bill by $95 the first month. I highly recommend them!

The whole process for switching my energy supplier to energy harbor was a very smooth operation! The customer service representative was very professional and courteous. He explained exactly what I would be receiving and talked me through the whole process of signing up. He sent email confirmations and even I received information in the mail. It's now been over a month since I signed up with Energy Harbor and I can honestly say that when I think of this company, I get a positive feeling. Energy Harbor is a company that I can trust and I look forward to being their customer for the next four years.

No matter what I've called or emailed about, their Customer Service can't be beat! They have been courteous, helpful & solve the issue quickly.

The agent came to my door in Rushmore clothes. He went through my bill with me and let me know about Rushmore's 3 year product. The process was easy and professional. No hidden fees, and when I spoke to their customer service agent, she was very cheerful and helpful.

Yall are stupid....like seriously....the rep told me to remember to call after the 3 month promotional rate..and I did! WOULD YOU LOOK AT THAT THEY DROPPED ME TO 6.2 cents per kWh! PEOPLE!!! Please dont be stupid and call to update the rate on time!!

Hi I would like to say that signing up with Spark Energy is definitely saving me some money and the help i received from the representatives was very helpful and efficient I appreciate it when the representatives take time to thuroghly explain to the customer about the services that will be given. Thank You

constellation was told by Nicor that I couldn't switch even though I was within the 100 day time stamp according to Illinois law. Nicor was of no help. they just kept telling me no. Way to many people getting involved in this to get it right. I'm stuck with Nicor for a year according to them before I can switch.

The switch to Energy Harbor was as simple as responding to an email. They took care of everything, and so far I have saved about 20% on my gas bill.
