Our Reviews

  • Highly Recommended for Heating and Cooling Service
    We have been using Nortek for the maintenance and repair of our air conditioning and heating units for years. They have, without fail, provided us with tremendous service. We have become very comfortable with Ron and his crew, who perform the onsite work, and Justin, their man in the office because we know they are capable professionals. They are knowledgeable, personable and straightforward. Years ago, in summer, our upper floor would always be hot despite how low we set the air conditioner. Ron suggested a forced air a.c. system to cool down the upper floor. We went ahead with the project and it was truly one of the best decisions we ever made. It’s a lifesaver. It works so well that there are stretches of time where we don’t put the house a.c. on. We highly recommend Nortek.

  • We Trust Nortek With Our HVAC Year After Year
    Ron came to do my A/C maintenance again. He was punctual and very efficient. But what I really appreciate is how he cares about me and my HVAC needs now and in the future. I know that I can trust them to take care of me, without taking advantage of my situation. 6 months later…Just had my HVAC maintenance check up. All is still great with the new furnace Nortek installed a few years ago. Nice to know that I can always rely on the technicians to keep me comfortable.

  • Fixed an AC During a Ninety Degree Heat Wave
    Nortek personnel went out of their way to fix our downed AC unit during the recent long ninety degree heat wave. Ron quickly diagnosed and explained the problem in a very understandable way. Jason stayed after normal closing hours to expedite ordering the necessary part for my Trane AC. When they discovered that the parts distributor sent the wrong part, Emillio went on his lunch break to Bollingbrook to get the correct one and to complete the installation when promised. Very satisfied and relieved that our AC came on right away and has been working well since then.

  • You Won’t Be Disappointed With Their Furnace Replacements
    Suppose you are looking to replace your furnace. I promise you won't be disappointed. I chose this company from the reviews I read. And every review was 100% correct. They would call and update every step of the process. The calls started coming in as soon as they were hired. When they filed for the permit, and when the furnace was expected to arrive. Just above superb in communication. They arrived on time. The communication was awesome. The workers were friendly and explained what they were going to do as they went along.

  • Nortek Came Through When Our Furnace Failed
    Our furnace went out and their technicians showed up within four hours to diagnose the problem. A mouse had chewed through a wire nut and shorted out the entire system. The technicians were great and did all they could in the initial visit to repair the system. They promised to come back the next morning and they did just that. The system (that they installed) was up in a few hours and the shorted thermostat was replaced with a temporary one until a new one arrived. Technicians were awesome. They let us know what was going on, showed us the damage, and quickly responded as promised. Highly recommend this company.

  • Found My Forever HVAC Company
    Nortek come out to my new home last winter to check the furnace. They pointed out things to me that my home inspector DID NOT. That impressed me immediately. Today Nortek came out to check some things on the A/C unit. The technician, Zach, explained everything he did in layman’s terms. I am confident going into the winter season that both my furnace and A/C units are in good operating condition. I have had two great technicians. Not a coincidence. I believe this is how Nortek operates. Ethical and honest. Justin, in the main office, even called to tell me my equipment was due for service, for which I had already paid. He didn’t have to do that. That was on me. I have found one GREAT company to work with!!!
