HEAR FROM A RECENT CUSTOMER OF OUR PLUMBING SERVICES
I'm new to the Mount Prospect area and am very happy to have stumbled upon Intelligent Service for my plumbing, heating, and cooling needs. I am a first-time homeowner and used Intelligent to fix several of the problems that were found on our home inspection. Every single person who has come to my home from Intelligent has been super kind, knowledgeable, and excellent at what they do. As a woman, I also love that they send a picture of the service technician you can expect to come to your home as an added safety feature. They've earned a customer for life!

Common Plumbing, Drain & HVAC Questions
What are signs I need HVAC repair?
Unusual sounds, poor airflow, or inconsistent temperatures may mean your system needs professional service.
Why does my drain keep clogging?
Hair, soap residue, or grease buildup are common causes. Persistent clogs might indicate deeper line issues.
How often should I schedule plumbing inspections?
Annual plumbing checkups help identify leaks, wear, or pressure problems before major damage occurs.
Can HVAC problems affect indoor air?
Yes. Dirty filters or poor airflow can lead to poor air quality, allergies, or mold issues.
Do you fix water temperature problems?
Absolutely. We identify the source—whether it’s in the plumbing lines or heating system—and restore consistent hot water.
What makes Intelligent Service different?
We focus on honest communication, skilled work, and treating your home with care—making every repair or install stress-free.
