We specialize in installing high-efficiency air conditioning systems tailored to home size and climate needs.

We ensure optimal airflow through precise ductwork design while providing energy-saving recommendations that reduce cooling costs by up to 40% compared to outdated systems.
Heat Pump Maintenance
Our preventive maintenance plans cover comprehensive heat pump inspections, including coil cleaning, refrigerant level checks, and electrical component testing.

We have a broken damper in our duck and Ran did the initial check before scheduling the fix. He throughly evaluated our HVAC system and gave a lot of good information and explained what to do. He was extremely friendly and knowledgeable. We appreciated his work and professionalism. Services: HVAC duct & vent repair, HVAC system maintenance

WOW! I recently had the opportunity to purchase a Trane HVAC system from NORTEK. I had a wonderful experience with this outstanding company. I made an appointment and Ron came for the initial meeting and estimate. He was very thorough and explained every detail about the system I could purchase. Eventually I received a call from Lisa, the president of Nortek, to discus the installation of the unit.

She was so pleasant and professional with my wife, which is not the norm when dealing with companies now. Ron, Manny and McKenzie came on the scheduled day. They were amazing starting with McKenzie he greeted me and laid cloth on the floors to keep the work place and my home clean. Ron and Manny arrived to install the unit. They were extremely professional, thorough and had excellent workmanship.

I also spoke to Justin who takes care of the administrative portion of the business ( i.e. rebates and registration). He was extremely helpful. I would highly recommend Nortek for all the reasons I stated above. I give Nortek 5 stars.

Called 03/07/22 and made an appointment for the next day. Ron came out and cleaned/checked our furnace and everything went great. He was very good! Glad a neighbor recommended Nortek, and I will have them back to check/clean out air conditioner in the spring. Happy with everything.

Nortek Environmental, EXCEEDED my expectations! The entire team that assisted me with my mom's house. (Lisa, Ron, Manny, McKenzie & David). One of the best decisions that I ever made! Very satisfied with the work! I'm sure my mom would do cartwheels if she could. LOL! I would highly recommend Nortek, any day of the week.

I have been dealing with Nortek for years after referral from a friend of mine. With Nortek I always know they fix only what is necessary. I have dealt with Justin in the office who is always friendly, helpful, and professional. Ron and Manny have been to my residence before and are always professional and courteous. If you are looking for honest work at a fair price, call Nortek.

Jan 2, 2022, 20:00. My heater began acting funny, flame on, flame off, repeat. I placed four calls to four different companies. Two picked up. Manny at Nortek was the only actual technician to answer. He was at my house within 40 minutes, quickly figured out a few things that could have been the problem and took care of them. Here we are 3 hours later and the heater is working wonderfully. I will definitely be calling on Nortek again for my HVAC/AC needs.
