“fun to soar with the eagles......”
As always Northside has been efficient trustworthy on time easy to work with and courteous. Almost sounds like a boy scout.... LOL these guys are the best and Chris continued with the reputation and service that over the years I have come to appreciate and expect. Thanks Chris

- Mary
“Very Thorough”
I highly recommend Northside Air Conditioning. Chuck Parker promptly reviewed our broken system and gave us several upgrade options. Within two days they were here to update our entire system, inside and out including the furnace. The techs, Spencer Murray and Jamar Johnson, were very professional. They were hard working despite the weather being in the high 90's. They took the time to vacuum any debris that had fallen on the floor. They also inspected every vent in the house and found one vent had a quarter size piece of insulation and promptly removed it. We were very pleased with the service provided by all employees at Northside Air Conditioning.

“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
“$405”
Mike, the technician, was very, very good. He diagnosed and determined the problem. He had to spend a long time doing that, and the weather was bitter cold!

- Stephen and Jane Noble
“Reliable & Dependable”
I have used Northside for over 7 years they are reliable and dependable.

- Kathy
“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!

- Alischa
