HVAC reviews in Atlanta, Georgia

I used Smart Mechanical to replace my 3 ton 18 years old furnace and ac system, they came on time and took 5 hours, they know what they have to do, so nice and kind, they finished and cleaned perfectly, I'm happy with this company and definitely recommend to everybody

They were responsive, courteous, and very professional. After they looked over my old ac system, they show me the steps of the process, and help to choose a new AC System. They did really great job!

Always professional, and explained what happened clearly. On-time to the appointment. If you are unsure about your HVAC system, AC replacement does a great job of explaining what is going on and what needs to be fixed. They were helpful to diagnose the problems, but not pushy about it.

My air conditioning was not properly cooling. The company was able to come early next day and do a full diagnosis and correct the issue. The technicians were very knowledgeable and filled me in on procedures. I will be using them for any future repairs and maintenance.

AC replacement guys were very knowledgeable and they explained easily for our air conditioning problems. They repaired the AC compressor and then it was working perfectly. I was satisfied with the great service.

My friend highly recommended me this company to fix my ac problems. They did a great job, and I recommended my family member to replace their ac units. They were really satisfied with the service. I got $200 in cash as their refer a friend promotion. It’s Amazing.

I have been using this company for over 12 years. Javier and his team installed a new ac system for 4.5 ton. Since then, it has been working perfectly. I just had a minor issue and they came fixed it quickly. They are just awesome and very knowledgeable. I highly recommend this company.

I had some issues about my old ac system, and a couple of companies checked and they tole me I needed to replace my outdoor unit. My neighbor told me they had the same issue and Smart Mechanical company fixed instead of replacing with reasonable price. So they highly recommended this company. They came to my house right on time. Technician explained what it happened and they just fixed. Since then, it has been working perfectly. I save money. Thank you, Smart mechanical.

I recently had my two HVAC system serviced, and I couldn’t be more impressed with the experience. From start to finish, the technician, Greg, and Carlos, manager, were very professional, thorough, and—most importantly—honest.
What really stood out was that there was zero pressure to buy unnecessary products or upgrades. Instead, they focused on what actually mattered to maintain my system efficiently and extend its lifespan. They took the time to walk me through what they were doing, explained how everything works, and even showed me simple maintenance steps I can handle myself.
One helpful tip, was about furnace filters. They recommended high-quality, budget-friendly alternatives that perform just as well—explaining MERV ratings, how often to change filters, and how to balance airflow with filtration, independently if I chose to purchase such options from their website or not. That kind of practical, cost-conscious advice is rare and appreciated, therefore, I chose to purchase the filters from their site.
They also gave clear, easy-to-follow instructions for routine upkeep, so I can avoid bigger issues down the road.
If you’re looking for HVAC service that prioritizes your home’s needs, your budget, and long-term reliability over quick sales, this is exactly the kind of service you want. Highly recommend!

I recently scheduled a tune-up on my heating system with Aire Serv of North Atlanta, and the experience could not have been better. From start to finish, the team was professional, punctual, and truly focused on customer care. My technician arrived right on time, explained everything he would be checking, and walked me through the entire process in a way that was easy to understand.

He took his time inspecting every part of my system—cleaning components, tightening connections, and making sure everything was running safely and efficiently. I never felt rushed or pressured, just genuinely taken care of.

What impressed me most was the honesty and transparency. There were no surprise fees, no upselling—just quality service from people who clearly take pride in their work.

If you're looking for a reliable, trustworthy, and knowledgeable company to handle your maintenance, I highly recommend Aire Serv of North Atlanta.

Highly recommended!
This HVAC company came to my parents’ home in East Cobb to fix their heating system right as a cold wave arrived, and they were amazing. They responded super quickly, offered a very fair price, and did an excellent job. I especially loved that they notified us in advance about which technician was coming — it made me feel very safe and comfortable.

100% recommended!
