See What Our Customers Are Saying
    “Josh was very helpful!”
    He even helped fix a decoration within the classroom that I couldn't reach. He was super friendly and even answered some students questions as he worked.
    - Carlos H.
    “Wonderful Technicians”
    We're Northside customers for 2 years now and I am very happy for the services they make. The only company who washes the coils every time someone comes in. And will give you an honest result whenever they find something wrong with the unit. Especially I still have an old unit from the previous company, they are trying to make that unit working good at all times. Today, Chris did my maintenance and tuned my my 2 units and I'd say he's a wonderful Aircon tech.

    “Customers for Life!”
    We have been Northside customers for over 10 years. We would never call anyone else. We constantly refer this company to others. John D. is as good as they come! He is always professional, thorough, punctual, and informs me of what is going on with our systems & what we can expect from them for the upcoming season. Additionally, he recently offered to get warranty information for some of the equipment in our new home. He called me back with the info within a day as he promised. This level of service is amazing! Customers for life!
    - Marcey
    “Above & Beyond”
    Excellence deserves recognition and reward. The team of employees sent to install my HVAC unit no doubt are a product of your leadership skills! Well Done to Tony R., Jamar, Jason & Tamarus. This experience was more rewarding than buying a new car! All my referrals will go to Northside AC! Thank you Tony H. for selling the anti-sales lady! You'll go far! Today I'm living the dream with my Accu-filter!
