I had a really great experience. I have been a customer of this company for over 30 years. They treat their customers like family. I trust them and have always been totally satisfied. I can’t say anything but great things about Them!!

Our AC went out in the middle of a heat wave on a Saturday night. We called Oelerich HVAC and told them that we could endure the heat over the weekend but even so on Sunday morning the company owner, Jerry Oelerich called and made arrangements to stop by Monday morning. We decided on the unit we wanted but due to Covid and the ongoing heat waves nationwide, there were limited supplies of that model. Jerry and his team called around and found the exact unit we hoped to get. The next day was the hottest of the week and Nick was sent out with the new unit. He worked in the heat all day and that evening we were basking in the cool air. I cannot say enough about how quickly the Oelerich team worked and the concern they showed. They recommended the top rated products and at a reasonable price. Great team! Shout out to Judy on the phones too.

The company responded immediately after I called for the furnace to be checked. They clearly explained my options and the steps involved. Very straight forward, fast response, on time, respectful, cleaned after job was done, competitive price. Nicolas the technician that performed the job was puntual, polite and knowledgeable. I definitely will keep this company for future services.

Mike did work on the hot water heater that allowed hot water to get to the kitchen sink faster. He was amazing and deserves credit for being very responsive. Thank you.

We strongly recommend Oelerich HVAC, we have had them maintain our units for 16 years. Jerry goes above and beyond to answer your questions on the phone and as needed in person, to make sure you’re taken care of. We had to recently replace our Furnace and we are very happy with the price, installation and will continue to have them maintain our units. Nick who installed the product was very efficient, high attention to detail, answered questions and extremely professional.

Nick was very polite and considerate, he answered all my questions, was careful with my floors and was very pleasant. The Trane furnace I replaced was installed 21 years ago by Oelerich and maintained by them. They will be maintaining bith the new Trane furnace and the vew Trane air conditioner they installed, thank you Nick & Jerry.

They were supposed to have serviced and cleaned my HVAC system as a part of my purchase of this property. They didn’t even change the filter in the furnace. HVAC 101. The AC had only 50% refrigerant. When my pipes iced up I was told to get a new thermostat all the while being spoken to rudely. They were also supposed to take care of a percolating water heater. They said that it was operating normally. A percolating water heater is not normal. I will never again use them.

Call to make an appointment for a diagnosis on my heater on July 2. A technician came and took 3 minutes. My concern is that replacing a heater is very expensive and in addition to the inconvenience it had in winter, it lasted several days without heating. I told the technician that 2 people had come to check my heating and I do not know that one had changed a part and it was not working anymore ... He opened the gas tap and it effectively worked. I asked him if that was it? I needed to be sure that it worked perfectly. Didn't check anything else, didn't take the time to look at what I know about something electric, circuits, because the gas was closed? Is it because I have an accent? I asked him, is everything ready? his answer was yes! I asked him and for 3 minutes and open the gas tap You are going to charge $ 89 already? He answered me, yes. The best comes right now ... I immediately called the office and spoke to the person who answered, woman, and I told her about my concerns. She confirmed that for the 3 minutes that the technician was here, the service was charged! (I understand but the technician did not check anything else). I have tried turning on the heating and testing if it works or not or if it will stop working as before. I gas the area where my heating is and I fear that there is a fire or something similar. Tell me what I have to do, please? Who do I accuse in case of a fire? Do I have to call Comed to come and check the gas, or do I have to call another technician?

My heat went out and they came right out and left me portable heaters till they could install the new furnace. Very prompt and very responsive and they did an incredible job. Thank you again and I would highly recommend Oelerich HVAC to everyone.
