Do not leave them unattended in any rooms of your house. Practice good home ownership as you would do with any stranger combing into your house We have no idea who the real owner is. they seem to use different business names on occasion ??!?One technician said he was the owner when we do a search the ownership is under an attorneys name in chicago heights. Seriously stay away the positive reviews are probably fakes

This place is a joke. Initially dealt with them via AHS for my air handler. Paid about $600 for a…read moreFreon refill and leak sealant. About a year later call them out to take a look at the air handler; paid an $80 service fee and was told that it needed to be completely replaced. It took over 6 months and 2 visit to my home for them to give me an estimate for replacement with no price breakdown. Just a vague list of charges and a total price. Told Lacey that the estimate was unacceptable and was told "we don't provide a breakdown of price because it'll make the price go up". So unprofessional and inefficient. I wouldn't hire these people at all and AHS should really stop using them. Run the other way if you are considering using these people. Was able to get a reputable competitor out the same day and they too were outdone that an estimate over 15K was given with no cost or labor breakdown.

My husband found the listing for Kulacz and Sons in the Monee Home Pages. The first HVAC ad was two pages on Kulacz, touting no extra charges for nights and weekends! The owner Jake bounded up the sidewalk despite the temps in the mid-teens and the kickoff a few hours away. I had diagnosed that either the thermostat and/or filter to be the problem, scouted out my choices at big box, and presented them to Jake. He appreciated my research and concurred with my choices. That set the stage for myriad questions from me (less than 400) for the next 1.5 hours. Jake showed me how to complete my DIY project of adding some more wire pairs. Jake is so personable, energetic, informative and he charged us $50 less than we expected. My husband wanted to give him a tip, but he reserves those for his employees. Wow! No reservations whatsoever in having him return if need be.

I was told the diagnostic would cost $149. I asked to be informed of any repairs that had to be done. Technician checked the system and recommended replacing unit. We discussed replacement unit and cost. I was ready to pay deposit. In the next 10 minutes I was told that the model I selected is old and not available. New model costs $1000 more. I asked for a proposal to decide later. Technician told me that the visit costs $396. He said that he fixed air conditioner that was not working. He never told me that he is fixing anything. Through our the visit it looked like he was figuring out the problem. I talked to the owner and we agreed that any repairs that were done will be undone so that I do not have to pay for repairs. Then the technician removed all the wires from the board making both heat and fan unusable. He did not just undo the "repairs", but made entire system unusable including fan and heat which were working before his visit. See the photos to show what was done!

Reply to 2 reactions from Harmonic on my 1 star review…read more 1. A. & K. claimed A. fixed my heater Tuesday; lie. Bad customer service. Harmonic deserves 1 star, but all the starts below 5 are NOT indicated on the Google graphic of the numbers of review stars 1-4: false. 2. I never promised a review pull-down for a discount. My husband & I have better things to do than having an "agenda" as Harmonic accused. My husband was on a business trip. 3. I never called for an emergency repair. I did not switch from repair to cleaning & maintenance. I asked A. if C & M was possible afterward, unaware of 2 more with no heat. Harmonic called me "selfish" for this. 4. Any possibility A. and K. have unconscious biases towards people like me? They accused us of "manipulating" what? To save a few hundred bucks, while we spent in the tens of thousands at Harmonic's better former (aquired) company) you imagined up? 5. How could Harmonic accuse me of lying about my pain. Because I was able to and had to carry my 10 lb dog for a short moment because of her barkin? Why do I even have to explain my chronic severe back pain and mostly failed back surgeries and weak immune system? 6. I had no "agenda," but getting my heate fixed. I am not playing any "game" as accused. I am standing up for myself. 7. K.'s statistics on the number of my Goole reviews are false. 8. A. & K. are the ones who were "aggressive, harsh, unethical, disrespectful, and manipulative." Stop projecting and gaslighting. I wish I would remember to record conversations when I am alone with a person like A. Why did K pull down his absurd replies on Google?
