“Tommy was very response to the work I wanted done, a somewhat unusual water heater replacement. He carefully listened to our needs then executed the job perfectly. Both gentlemen who performed the work were very professional and pleasant to work with. Thanks to Tommy and his employees, I feel we have finally got our previous issues resolved. Thanks!!”

“Tom Mahoney is our Mahoney!!!!!  When you have an emergency he responds immediately.  With his top notch experience, our problems were repaired in no time.  I wouldn’t trust anyone else with our plumbing needs.  Tom is knowledgeable and honest!!!!!!  He has fixed many plumbing problems in our house.  I only recommend Little Tommy’s for everybody’s plumbing needs.”

“We suffered a flood after a prolonged power outage causing both our sump and battery backup to fail.  This resulted in 6 inches of water in our finished basement.  After leaving Tom a frantic message in the middle of the night, he arrived at our home very early in the morning wearing his wading boots and did not leave until he performed a thorough inspection of our furnace and a new sump and backup were in place.  Where Tom goes, we will always follow!”

“I have a house that is nearly 70 years old.  There is hardly a day that I don’t wake up to a new plumbing or heating or cooling problem.  Oh what to do----I know----I’ll call Tommy----He always can solve the problem!  For honest, reliable and quick service as well as customer friendly knowledge, there is no one more ethical and responsive than Tom Mahoney.”

“When we first moved to Lake Forest in the 1995, we experienced every disreputable and incompetent plumbing company on the North Shore.  In fact, we met Tommy after one of these companies poked a hole through our shower pipe and flooded our living room.  Tom is skilled at his trade; a congenial person; and a fine businessman.  Most importantly, he has rescued our family when the air-conditioner died two days before our daughter’s wedding during a 90+ degree heat wave and in a Christmas morning when water was pouring into the basement.  We have referred him to many friends and neighbors, all who would echo our endorsement.  Little Tommy is both competent and fair.”

“Little Tommy’s Plumbing Shop…what can I say?!  Tommy came to the rescue, AGAIN, on a holiday weekend when a frozen pipe sent water spilling into the laundry room at an alarming rate!  He arrived within an hour with a smile on his face and took care of business.  We were up and running in no time.  Thanks, Tommy, for a job well done.  We wish you great success in your new venture!  We will be recommending you with confidence to all our friends.”

“I called Little Tommy’s Plumbing Shop to repair numerous plumbing with our new home.  Tom returned my phone call promptly and arrived on time.  We went over the list of problems identified by the house inspector.  Tom was able to explain what the problems were in a way that I could understand.  He explained my options and offered a free estimate with a timeline for the job.  While working at our home, he always communicated the work progress and stayed within the timeline quoted.  All items were repaired and Tom remained precise, professional, thorough and neat through the process.  He often went above my expectations to make sure I was satisfied.  The price quoted was fair and there were no hidden costs or fees.  I highly recommend Tom Mahoney for any plumbing and HVAC needs and will call him again in the future.”

“These folks are experts in AC Installation and Maintenance in the Chicago IL metro area. Call them today!”

-M&M Mechanical Inc.

“I'm grateful to Little Tommy's for taking the time to assess our AC needs. We live in an old house, with three zones and needed to replace our 20-year old AC unit. There quote is easy to understand and were very responsive to every question. They installed the unit and overcame several obstacles with grace, including a wasp nest near the outside condenser unit. Our new AC is running smoothly, and the temperate/humidity is great. I really appreciate the $300 ComEd rebate information Little Tommy's provided, with the form already filled out and ready to mail in. Thank you!!”

“Easy to make an appointment, and when our plumber came in and he was so knowledgeable and friendly. We had some issues with our garbage disposal, and he even gave suggestions to prevent the same issue from reoccurring. He didn't rush, and was in and out in a reasonable amount of time. Pricing was reasonable. We will definitely call again with any other plumbing issues.”
