Super responsive and they do great work. They installed our two new AC compressors, and 2 years later on a hot summer day, one started making a weird noise. I called them the next morning, and they sent someone over the same morning to deal with it. Sergio was professional and courteous. read more

Poor communication & Indifference. OK Heating and Cooling was hired to handle an air conditioning repair at the building I rent from and has shown poor communication throughout the process. Initially, a technician visited on-site to diagnose the issue. He stated a part needed to be ordered, and he would return once it arrived. I understand parts are not always in stock and materials need to be ordered. This was a reasonable outcome. The problem, however, lies with the company's poor communication. I contacted the company's owner, Joe Petrucci, on June 14th, to inquire when the ordered part would arrive. This was days after the technician had visited. Joe stated the part was ordered, because it was not in stock, but he did not provide an estimated delivery date. At this point, it had already been established a part was ordered- the question was: when would the work be completed? I inquired again four additional times in the following days asking when the part was estimated to arrive, and my calls and texts were ignored; this includes calls to the office and Joe's phone. The temperatures are currently in the 90s, and I'm still waiting indefinitely without any clear answer. If you're looking for HVAC repair, I would suggest looking for other companies that value communicating with their customers, practice transparency, and are able to provide basic customer service. read more

Still using OK after all these years. No issues. I'm about to arrange to have them install my new Ecobee 4. They have saved me several times - like when my AC condensate line clogged and leaked all over my dining room just as I was about to leave for a conference. read more

With a recommendation from a friend we had Joe from OK Heating come out for a quote back in early July. We needed a new furnace and duct work done in one of the units of our building. He came through and inspected the job, laid out exactly what he would do and sent us a quote a few days later. Everything lined up with what we wanted so we gave him the go ahead. Fast forward to now, the end of September and no work has been done on our building. They do not return phone calls. They do not show up on the set date to start work. At least twice they blew us off the day we were expecting them to arrive. When we would call Joe he would give us excuses about things coming up. We had all of the preliminary demolition and construction done in anticipation of their arrival and 3 months later we are still waiting for them to even return a phone call. After several attempts to contact Joe or anyone at his company my fiancé finally spoke with him this morning (He blew us off again on the day he was supposed to start work). He told us that it's getting cold outside, and we should look for another company. To say that I am disappointed with OK Heating and Joe's professionalism would be an understatement. We had work under contract and all we expected in return for our money was for them to do the job they said they would do. I have worked with many, many contractors in my life and this might be the worst experience I have ever had. I would NOT advise doing any sort of work with this company. It a miracle they are still in business. read more

I was referred to Paolo at OK Heating by a family friend. At first he was fantastic, responsive, quick turnaround time to come out and take a look at our issue, gave what seemed to be sound advice. I have now wasted (and waited) over 6 weeks for his service quote. I've called, emailed, followed up by email... The only reason I am giving 2 stars and not 1 is that when I did meet him initially in person he was great. I just wish OK Heating would either send a quote OR tell us they can't do the work. At this point we have to move on as we need to get our issues repaired. read more

'ok' is an overstatement. OK Heating installed the furnace in our condo prior to our purchase of our home. For three years we had problems with the furnace and would call them to come out to take a look at it. If we could get a hold of them (only in the morning between 7:30-8am) they would come out 'when they were available' which translates to 'take the entire day off of work' and would only look at the furnace for 30 minutes - tops - and say they fixed it. Almost immediately after they left, the same issue would surface. I am embarrassed that we stuck with this for three years! Thank goodness we have a fireplace! We FINALLY called a different company and in one day and a repair man out, during a time window they established, and had the furnace fixed. Save your time and money, go with someone else. read more

I can't believe the 2 neg reviews? These folks are true professionals and did fantastic work. I've been in management most of my 50+ year career. I ran a small business with dad for over 10 successful years. My furnace/AC job took place this past winter. I even needed some follow up work in order to sell my home. They were prompt and NO CHARGE. They have their act together. read more

Settle in. This is a long one. But it's important for anyone thinking of hiring OK to read. My neighbor hired this company to replace her AC system. The very same day they came out to do the work, my unit's AC went down. Here's what happened. -Prior to disconnecting the condenser on the roof of the building, their tech was required to verify that it was the correct one. They failed to do so and cut into MY condenser instead. This is undisputed by the vendor. -They cut into it, replaced the piping, unplugged the internal plug, then drained the freon. -Once they cut into it, they contaminated the unit and effectively destroyed my condenser. -When they drained/stole the freon, they committed a federal crime. They are required to replace this to the pound by federal law. This is extremely expense and would cost at least $1000 to replace alone. -Without the freon, the unit burnt out as it ran without fluid in it. -There's also the assumption that once they realized their mistake, they actually put my original condenser back together. But I have no proof that that's the case. They could have taken it for parts and replaced mine with my neighbor's broken one. This is a very real possibility and would explain why it's not working. In that case, there's a very real case of possible theft here that I have been advised to pursue with the police. -Either way, they cut into my fully functioning condenser, replaced the piping, unplugged the unit, drained the freon, reattached a condenser (not necessarily mine) that is no longer in working order. And then they just left. Without saying a word. And just hoped I wouldn't notice? And Joe, the president, is suggesting he is only on the hook for the compressor within the condenser. He is actually required to replace the entire AC system, coil and condenser to original condition/working order, which included a matching coil and condenser. (Or the financial equivalent as reimbursement). He refuses to do so. Any HVAC expert, including the two i've consulted, will tell you that having mismatched parts will result a system that can easily break down. Premature failure-- According to the Air Conditioning, Heating, and Refrigeration Institute, "At worst, improperly matched indoor and outdoor units can create undue stress on your cooling system, resulting in an unnecessary, premature failure." Lowered efficiency of new unit-- Assume you replace the outside unit with a 16 SEER unit and the inside unit is an old 8 SEER unit. Your new outside unit won't run as efficiently as advertised because of the old inside unit. It'd be like tying a stallion to a donkey. Possibility of no warranty-- Since mismatched systems cause problems, some manufacturers won't offer a warranty for the new condenser unit if you don't also replace the evaporator unit. It is also not akin to what I had, which is what he is required to return me to. Evaporator coil and condenser unit must match. And furnace coil should match as well, frankly. All of this should be provided by him or be paid for by him to another vendor. Frankly, I don't trust him at this point to install a functional system or be in my home. He has ignored countless texts and requests for updates and information over the last several days and even hung up on me when I was finally able to reach him. Unprofessional at best. I'm also out over $400 having HVAC and electrical service vendors out to my home trying to figure out what happened. He has not offered to reimburse me for those costs. Instead of apologizing for the now three weeks in 90+ degree/high humidity weather with no AC, with an elderly dog with a heart condition who has been struggling with her health the last few weeks in the heat, Joe refuses to do what he is legally required to do--which also happens to be the right thing. Replace the AC unit, coil and condenser, new, matching. Like any reputable service provider who messed up would do. I was dragged into this. I didn't hire them, nor did my system have anything wrong with it. And now I'm out up to $5000 to replace it for absolutely no fault of my own. I'm in the process of filing complaints with the BBB, IL State Attorney General, and a police report for theft and damage of personal private property. My next step, if this is not rectified immediately, is to hire an attorney. I can't imagine how a company would mess up like this and not be willing to make it right. Disappointing is an understatement. There are so many great vendors out there, run by good and honest people. Look elsewhere.... read more

Very pleased with the work and integrity Joe and his crew have. I would recommend them as we will be using them going forward for our properties. read more

In February I decided to switch from LP to natural gas. To do this I had OK Heating come to my home so they could change the fitting on my furnace. This had to be a coordinated effort, since Madison Gas and Electric needed to make the final switch from the tank to the natural gas lines they installed last fall. OK Heating sent two technicians to my home in the morning to set things up. Then they came back later the same day when the person from MG&E was here to make sure the hookup was ready. The techs from OK Heating showed me what needed to be changed, then they made the change and were on their way in less than an hour. Great service and affordable is how I would describe OK Heating. I would recommend them and will hire them again when needed. read more
