    After having spent a considerable amount of time meeting with and evaluating a number of…read moreestablished plumbers to do a considerable amount of work at our home, including adding a large section of new copper piping, installing a Reverse Osmosis filtration system, installing a new water heater and also a hot water circular pump...for instant hot water throughout our home, we ended up convinced that Cahill Plumbing was not only a company of the highest integrity that could be relied upon, both now and over the months and years ahead, but that their team of licensed plumbers had the resources, knowledge and skill to do the right things the right way. We have had many of our projects completed now...with several more about to get underway and I am happy to report that we are 100% happy with our choice as well as all of the work that has been completed so far. On the day before the project got underway, Cahill's Plumbing Director, Andy Visconti...a man in whom we have complete confidence, called to review what his team would do and who he had dispatched to do the job. Three plumbers, two licensed and one journeyman, arrived on time, covered their boots, explained their strategy in detail, answered all of our questions and then worked efficiently all day, stopping only to answer any question I might have had and provide me with a detailed progress report. If they experienced anything unforeseen, which is bound to happen in projects of this size, they called it to my attention and explained their workaround solution. It was fascinating to witness their teamwork and creativity. Disclaimer: I should state that I had no prior relationship, either personal or professional, with Cahill or any of their employees, including those who did such excellent work at our home last week: Tyler, who managed the project...and besides being a kind and very friendly young man, is excellent at what he does; Austin, Tyler's very capable assistant and Matt, the rookie, neither of whom ever appeared to stop to take a breath. Working together, they were a formidable team you could rely on and trust. Bottom Line If you need any plumbing done at your home, be it a large or small project, you'd be wise to give Cahill a chance to do the right things, right! We rate Cahill FIVE STARS and are very happy and confident to have them available to be 'our plumbers' from now on! Cahill is a company you can trust and be confident in. Mm...did I mention how fair and reasonable their pricing was? It was!

I said what about a space pac type system. They said that would be more cost effective and quoted it at about $30K. I thought this was way out of line for the work and it felt like they just thought I wasn't going to get other quotes since I had been using them for so long. But I did, and after a bunch of quotes I went with Ireland Air, Couldn't have been happier. They were the lowest but they we a third less and seemed much more knowledgeable!

The boss, David Ireland, has been to my house to evaluate a difficult problem. It took him 15 seconds to find my problem and eventually put in a new air conditioner for me. He explains things clearly and is very experienced, very patient, and an all around pleasure. Then I had a problem which no one could solve for 3 months. A terrible blowing and buzzing noise throughout the house. It was making me crazy. Kyle, the wonderful guy in the office who schedules and does many other things, sent me a younger technician, JOE, who got right to work. He admitted that the noise was way too loud and not normal, and was the only person I had had thus far who thought the furnace/AC was working properly. He went through the whole unit very systematically and shortly explained what he thought was wrong. He proposed I order a part, went right then and bought one, installed it, and presto! - there was no more buzzing! This young man was professional, persistent, patient, and a delight to interact with. For me today, Joe was worth his weight in gold and took a major problem off my bucket list! .......But there's more - he found an issue with my office air/heat unit, changed batteries in related equipment that no one had done before, cleaned rust off the outside unit - which was a first, didn't suggest we replace the unit which is pretty old but thought a replacement part would serve us well for a time. Joe cares about his customers and their money, and is very careful not to err. I watched everything he did and was very impressed - and I'm pretty fussy about workmen! If you have what you think is a unsolvable problem, call and ask for Joe to show up on your doorstep! He even suggested we get new carbon monoxide detectors and tole us where to put them. He looked at our situation and equipment in a wholistic way and didn't miss a trick. L Weiss

My family's been using them and it's been progressively worse to the point I had to get the IL Attorney General's office and the BBB involved. Whether it's HVAC maintainence or roofing they've been nothing but trouble and downright abusive. Most recently they put $3000 on an elderly family member's credit card for a routine A/C check with no parts or repairs, then said he could get the money back if he bought a whole new system from them. (A/C checks are about $100 national avg.) Prior to that they misdiagnosed a furnace part (draft inducer) as having high amps and about to fail at any time, recommended a new furnace. The furnace and draft inducer have been fine 14 years since they said that. Before that they did a sloppy roof job by actually nailing shingles over the old shingles, much easier for an unskilled roofer except that the old shingles start rotting between the new shingles and the membrane. Please find a more reputable company like Cahill, etc. for furnace or a/c maintenance and anyone else for roof work.

We called back & left a message asking them to return and help us out. I imagine they were busy on that day as it was 84 degrees, it's been a week without any follow up. After returning from a long day at work (to be followed by another early morning), I was able to solve the problem! It turns out the work was left un-finished, and the HVAC would not function due to some electrical tape. I'm not an expert, but may I politely suggest using better quality tape next time, or putting the MF'ing furnace back together. Thankfully, I was able to complete the job late the same night by removing the electrical tape placed over the safety switch, and then used a screwdriver to reassemble the cover, which then closes the safety switch. Still haven't heard back from my 2nd follow-up call and the photos I'd provided. In reviewing the bill I see I only paid for a diagnostic and the materials, but I think they should make it explicit if the customer is expected to help out with labor. Maybe shop around?
