Update:Mike Williams had to come out a 3rd time because the supervisor didn't know how to not have the fan running all the time apparently. Got a call from the owner himself to make sure I was satisfied in the end. Was working with one of the girls that answers the phones and she was nice throughout but it seemed they really didn't want to refund my money no matter how dissatisfied I was, but in the end they refunded my money. But I still hold to my one star rating. If I could choose no stars, I would. Based on the work performed, I should be suing Mike Williams. I was screwed over by Mike Williams; they overcharged me by a lot. I called "another company" to see what the prices would have been if they would have came out and done the same work, they are estimating I would have saved something over $300. Mike Williams pulled one over on me. After one week of Mike Williams work installed, my circuit breaker now popped and there is smoke rolling out of my vents and a horrible electrical fire kind of smell throughout my house. "Another company" says they can be at my house in less than an hour but Mike Williams says they will put me on the schedule and they don't know when they can be here. "Another company" came out and looked at the issue. First, Mike Williams installed my capacitor and circuit board with zip ties, which is not to code. Second, since the capacitor wasn't installed properly, it was touching metal which in turn caused the smoke in my home, and luckily the circuit breaker tripped and there was no actual fire. I then needed a whole new motor because it seized up due to the capacitor almost catching fire. There was also a water leak in the furnace and "another company" said he could use a caulk that would be safe to put on it because right now it isn't safe leaking on the wires. But when I asked Mike Williams if they would do that, they said that they needed to replace the whole thing and they don't suggest just using caulk. Also I was told by "another company" depending on my budget I can get a furnace as low as $1600 but Mike Williams insists that the lowest furnace I can buy is $3500. Also they claim to have a "100% satisfaction guarantee" and I'm completely not satisfied with anything they did, but they will not refund me. They have a "Work performed to code" guarantee and this clearly was not done, but they will not refund me. They have an "Apples to apples best price guarantee" and clearly they have the worst prices out there and they are making me jump through hoops and insist that there is no one out there better than them, but they still haven't refunded my money. They also claim to have "LOCAL" family business for over 30 years and this is a requirement for the "apples to apples" price compare.."another company" is local and Mike Williams is not even out of Bloomington. But guess what! I still don't get my money refunded. NEVER CHOOSE MIKE WILLIAMS, THEY WILL RIP YOU OFF!!!!!!!! ABSOLUTELY CHOOSE LARTZ HEATING AND AIR CONDITIONING!!!! read more

My husband and I have been customers of Mike Williams since 2001. We've been exclusive to them ever since due to their professionalism and friendliness. They've replaced our sump pump, repaired our bathroom plumbing, and also worked on our central air conditioning. We are even members of their preventative maintenance program for our heating and air conditioning. We have always been pleased with their technicians. However, recently one of the technicians kind of rubbed my husband and me the wrong way. It wasn't a big deal, but it made us not exactly trust what he was telling us. Luckily, one of the very sweet ladies in the office gave us a follow up call asking how the visit went. I was reluctant to tell her what was bothering me because I felt it was a little silly. But, she could tell I was a hesitant with her and inquired to what my thoughts and feelings were. I told her about my experience with the last technician and how it had not compared to previous service we had. She listened patiently as I went on to explain the situation. Instantly she empathized with me and we worked on a solution to my dilemma. She answered all of my questions in regards to the service. When it came to the technical questions, she couldn't answer them. However, she did set us up with another appointment with a different technician to come out, at a time that worked with our schedule and at no additional cost, to discuss all of the mechanics of our air conditioner. When the other technician, Eric, arrived... He was terrific and absolutely pleasant to talk to. He listened to all of my concerns and addressed them all thoroughly. After Eric left, I was so thrilled that the personnel at Mike Williams were willing to listen to me and make things right. They really do stand behind all of their guarantees. read more

WARNING; The Mike Williams Plumbing scumbags are now spoofing phone numbers. Hired these lowlife scumbags for a plumbing repair in July 2020 and made the mistake of paying by check. The bottom feeders misused the numbers on the bottom of the check to STEAL money from bank account via wire fraud. The unauthorized withdrawals (multiple withdrawals) were reported to every federal governing agency and with the bank that processed the wire fraud. I have repeatedly asked to be removed from every list this scumbag ring of thieves has to no avail. I recently received a spoofed call from Largo FL. The scumbag called identified themselves as a Mike Williams Plumbing representative. I went off on the scumbag spoofed called. I wished her the worst possible circumstances a human could wish on another "human" yet the bottom feeding lowlife continued to talk over me.BEWARE of ANYONE representating Mike Williams Plumbing. These people are evil predators and should be in prison but since this is lawless Illinois they should be permanently eliminated from the civilization as they pose a very real threat to society. read more

From the minute I called Mike Williams, and I've always found this to be the case, everything is handled professionally. I know the problem is going to be fixed right the first time. Ryan was the technician who came this time, and we've had him come many times in the past. He is not only knowledgeable, but personable. He works quickly, but competently and explains all of the options clearly. This time it was the emergency shutoff for the toilet that had to be replaced. Last week we had to have a new sump pump put in and Travis was the technician. They do seem to be expensive, but I actually signed a contract with them so I get a percentage off. It's just nice knowing who to call to get something done and get it done right. read more

I cancelled our monthly service contract in April and was guaranteed that it would end then. It is now currently July and they have continued to charge me monthly since then. I have telephoned, emailed, written, and I eventually had no choice but to drive to the office and walk in to speak to a person who was of no help. I have been shuffled from representative to representative. A managerial person guaranteed me a complete refund and much to my surprise I not only was not refunded but in fact they charged me once again today. read more

Great place! My furnace and water heater needed replaced. Mike Williams came out and took care of my family immediately. Dane and Layke were very friendly and easy to work with. I wasn't able to be there during the installation and Layke took the extra time to review how to adjust the water temp with my daughter. I spoke with Layke a week later and he called my daughter by name. Shows they really care and considers us family. I will always use this amazing company and recommend to anyone that will listen! read more

The techs were running a little behind but I was notified by the office of the condition. Thanks. When they arrived, they got started quickly and drained the old water heater (22years old) and went about the business of installing the new one. Seems like no time passed and they were through. We checked all the faucets for debris as the water had been shut off. in 5-10 minutes everything was clear. They cleaned the area and were gone. Quick, timely, and clean. Very nice job. read more

Greg came out to my house because the air conditioner would not turn on. He checked the thermostat right away and sure enough that was the problem. He replaced it and everything is working great now.

Ryan was the tech assigned to replace our sump pump. We also had to run new pvc pipe to channel the water away from our house foundation. Ryan explained the job, showed up on time and completed the work in a timely manner. Williams is expensive but I believe you get what you pay for. No complaints here ! read more

Great service & reliable, knowledgeable technicians, but I feel their prices are overrated. I did a bit of research an found great disparity between the replacement parts quoted to me and the same parts on line. However, Mike Williams P/H is trying to make this right for me. read more
