WHAT OUR CUSTOMERS SAY

“Ryan Penman is too damned slow to ever use him again. I’ll never use Service Now if he going to be given the job. I was about to call to see if he got lost between here and Lowes .. 1 mile, because he was gone so long with our water off. All had to get was a ball valve!!!!!”
- Ronald C.

“Ethan was out today. He did a wonderful job. Helpful, explained my concerns and how to keep my furnace working properly. Very friendly. Highly recommend his service.”

- Karen K.

“I have been using ServiceNow for over a year, and while the technicians are excellent, the front office leaves much to be desired. They are consistently rude, often do not listen to your concerns, require you to repeat your issue multiple times, and still fail to get it right.

After more than a year of service, I have decided to stop spending my money on a company that treats customers this way. Jenean, in particular, provides the worst customer service I have ever experienced. If you find yourself on the phone with her, expect a long and frustrating conversation where you will feel neither respected nor valued as a customer. She seems more focused on being right than helping you, often talking for three to four minutes without interruption about unrelated topics when she is unable to assist you, rather than simply stating that she can't help.

After enduring numerous unpleasant interactions with Jenean, I have decided to take my business elsewhere.”

- Laura J.

What’s That Smell Coming From My Furnace?

If your furnace is producing a strange smell, you should always treat it with caution. While the cause for the odor may be benign, it could just as easily be harmful to inhale. When in doubt, always open windows to ensure ventilation, and evacuate your St. Charles home.
