HVAC reviews in Marietta, Georgia

We replaces a 2-ton unit and a ductless unit. They sent a 4 person team to do the job. They were respectful of our floors and home putting down drop cloths to ensure no damage was done.

They kept me informed during the entire job. The job was completed in a timely and professional manner!

It was amazing how quick and professional they got the job done! New coil , new condenser , new furnace and more details plus useful tips about how to monitor the L40 smart thermostat! I am so grateful for dealing with cool mechanical! They great people!!

If I could leave a negative number I would. Their customer service is awful. For over 2 weeks I have been waiting for a supervisor to call me back. I have been passed around the building to people and promised so much. Since the instal we have had issues. To the point they issued money back and a extended warranty. We bought from CostCo and assumed it would be a great experience due to their standards. We dropped over 30K on two units. It has been a train wreck since. We have ceiling damage from a leak. They didn’t install the flex wrap on our pipes when I asked them to at instal. The first service person who came out blamed a dirty filter that they had serviced. The water leaks continued and they sent a manager out. He figured out the issue and promised it would be fixed. He promised an email with the price quote the following day. Nope, never came. A week later I called back and asked to speak to a supervisor. Nope, one one called me back. Called agin a few days later, and was promised one would call me back at 430. He did call, promised me he would get things handled and promised to text me with his direct cell. Nope, never did. Called back a few days later and was promised he would be in touch and would get things ordered. Nope, never did. They did schedule an appointment to come out on 9/5 between 8 and 12 to fix the issue. Well guess what, at 12 I had not heard a word or seen a service person. So I called again, asked for a supervisor and got put on hold while they found one. I was informed by that supervisor that they had gotten an email this morning advising to schedule someone to come out. She didn’t even know I had been waiting all morning for a service call. Again promised someone will call me back. Guess we will see. Disappointed in Costco for the partnership with this company and the horrible experience. I would never recommend this company to anyone.

Purchased a top of line Lenox heat pump from Cool Air Mechanical using Costco discounts. Great deal. I worked with Jacob Blanchard who managed the sale from day one till completion. Jacob stuck with me from beginning to end answering all my questions both technical and financial. He treated me with respect and I never felt pressured or hurried. I enjoyed, being an engineer myself, his system and technical knowledge which he explained in detail. Lenox is a well known quality product and Jacob a true professional. I recommend them both.

System installed when promised on time. Install crew Jean Paul and Ash arrived early, got to work right away and finished ahead of schedule. They were both professional and took care moving equipment thru house. They cleaned up the mess and helped with the thermostat and app setup. Then reviewed operation of the system and app with me until I felt comfortable with the overall operation. All in all this has been a great experience and strongly recommend Cool Mechanical especially Jacob, Jean Paul and Ash as a team.

Overall happy with my experience. Got a whole new HVAC system through Costco/Cool Air Mechanical. We got the highest end variable speed system they offered, and in the end it was a similar cost to the lowest end systems offered by other big players. The sales guy was easy to work with and honest. The install crew was fast and professional. They encountered an issue with the system near the end of the install, and they ended up spending several hours tracing the issue down to a single part on a printed circuit board. They had a replacement quickly brought out and had they system up and running. I was impressed. The variable speed is a really nice feature, and my gas bill seems to be lower. Hopefully the results stay the same for when it gets hot.

Based on the five-star service I received, I could write a lengthy review… but in the interest of time (mine and any reader) I’ll try to bottom line it! Nearly everything about this experience exceeded my expectations.
1. While shopping in Costco, I requested info about a new HVAC system from David Bamidele, the consultant at an in-store kiosk. David was professional and engaging. He explained that Costco‘s sole partner in this business is Cool Air Mechanical and they use Lennox equipment. I gave him my contact info and within 10 minutes Cool Air Mechanical called to schedule my HVAC assessment.
2. Stan Bailey, Senior Comfort Consultant, visited my home five days later. He was professional, knowledgeable, and engaging. He asked questions about my current system and my expectations with a new system. He listened carefully and designed a proposal with 3 options that met my needs. I was able to review the options and ask questions while he was still on site. Stan was amazing, competent and accommodating. He did everything a great salesperson does to provide a frictionless path to get a “YES” from their customer. Considering the size of the investment, he made it easy for me to make my decision with confidence.
3. Luis Alvarez and Abnel Medina installed a complete HVAC system, additional air return and smart thermostat less than two weeks later. They arrived early and explained their work order to ensure it aligned with my understanding of the plan. They were careful to prevent unintentional damage to my property. They worked professionally and proficiently, finishing the job in about four hours! Luis instructed me to download the Lennox Home app, ensured the new thermostat was programmed and connected to my Wi-Fi, and demonstrated basic functions. Luis and Abnel walked me through the installation – inside and out – and ensured all my questions were answered. I could not have been more impressed with the expertise of both installers!
4. Throughout the entire process – from first encounter in Costco through installation – the team at Cool Air Mechanical was attentive, accessible and accommodating – especially Melissa and Shelby. Their communications via text, email and phone ensured questions were answered before I asked!
My only regret is that I can only give the Cool Air Mechanical team five stars! I hope management recognizes each of the individuals who expertly represented their company – especially Stan Bailey.
I’m thrilled I bought my new system through Costco and Cool Air Mechanical. I HIGHLY recommend them.

10/3/24: First winter heater checkup of our systems using CoolPro. John was great! Good to go for the season. Another five stars⭐️⭐️⭐️⭐️⭐️

Excellent service. This was our first time using Coolpro for Spring and Summer tuneup.

The tech was professional and careful.

Besides the tuneup, he also replaced a malfunctioning thermostat.

It was important to me that a Trane technician serviced our three units.

Happy and will continue to use Coolpro!

Awesome job! On time, communicated and got the job completed super fast! I will definitely use them in the future! Hung large mirror.

Great company and people. I read other reviews and it sounded like a great choice and it was. Tech actually showed up early and diagnosed and repaired everything with my AC within about 30 minutes. Rates are very fair as well. Zero complaints here. I’ll be using CoolPro again for sure!

Update: June 9th 2025 - had them replace my whole AC unit in my condo. They did a great job and the install looks great. You can tell they took care when setting everything up. Everything working excellent. The crew was awesome. Definitely my go to for HVAC maintenance and repairs.

Great and timely service!! They were able to diagnose the problem and make the repair to our cooling unit. We will definitely use Coolpro again.

The young man who came out was very polite and helpful. And he did waive the callout charge when I complained about the cost of the thermostat which he removed. I know that home repair costs have gone through the roof but to aim to charge $169 on top of $89 callout fee to install a non programmable thermostat which costs less than $40 and took five minutes to install is simply a complete ripoff. Plus they could advise that there is a 75% rebate on smart thermostats that makes the corresponding model cheaper than the non programmable one. It’s a shame because I was very pleased with their work and cost when they replaced my aircon a few years back. Different times.
I changed my star rating to four because I appreciate taking the time to respond and the young man who came out was very professional.

Lee and his team are simply the best! They make a commitment, and have never disappointed me and my family for over 20 years! Their work is on time, done right the first time, and done with professionalism! Those are extremely rare qualities in any contractor that you call today! His team is Patient and willing to answer all of my questions, thoroughly and the way I can understand them.There simply is not a more reliable HVAC professional in Atlanta.

My experience with Coolpro Heating and Cooling has been nothing but the best. Between installation (HVAC) and service, I would highly recommend them. Lee the owner was upfront about everything. Ruebin was a wizard with my installation and John is a great service technician for up keep. Add Nick to the list of great service technician. This time it was Taylor providing the same outstanding service I am use too from CoolPro.

Customer service and resolving issue was fantastic but didn’t tell me there was a labor charge of $285 plus the $89 diagnostic?! Despite being thrown for a loop on labor charge tech was good

Edit: Lee called me and said they refunded me part of the money which was awesome and 100% fair. Would recommend!

Got Two units serviced, The technician was excellent answered all my questions and made several helpful suggestions. On time, professional, and courteous. Setting up the service was also very easy. Highly recommend. *****

Lee and his team at Coolpro did an outstanding job replacing our entire HVAC system. From start to finish, Lee's professionalism and prompt, clear communication made the process seamless. The installation was top-notch, with great attention to detail—highly recommend Coolpro for anyone seeking reliable, high-quality HVAC services!

Wonderful experience, thank you! My 20+ year old AC unit stopped working. Coolpro Heating and Cooling was recommended by a friend and I understand why. Scheduling an appointment was super easy. Great customer service! I was given a two hour repair window and the technician, Lee, arrived early. Lee, professional and kind, diagnosed and fixed the problem in under an hour. Their prices are reasonable and their service is top notch! I highly recommend Coolpro Heating and Cooling!

Simply put, this company is fantastic. They go out of their way to make sure the job is done right. They are honest, hard working and will give you a fair price for the work that is done. I can't recommend them enough. If you need HVAC service or if you find yourself stuck in the middle of the Georgia summer without a AC system this is the team you want!!

second time I had CoolPro out - on time and courteous, quickly diagnosed the issue and fixed it. The second time I thought it was going to be a $600 issue, it was an adjustment and only charged me the diagnostic fee. These guys are honest and trustworthy - highly recommend!

When your 20-year-old Trane unit dies in the middle of a Georgia heat wave, you learn two things real fast: 1) kids actually can melt, and... 2) who you call for HVAC matters.

We were referred to Lee at Coolpro by a custom home builder who’s used them often—and now we know why. From the moment we reached out, the experience was top-notch. The quoting process was clear and fair, their follow-up was consistent (without being pushy), and every single person we dealt with was professional and respectful.

They replaced our entire system quickly, cleanly, and just in time to save our family from turning into a puddle. Highly recommend Coolpro if you like cold air, honest people, and surviving summer with your sanity intact.

Lee came out the day after I called for an estimate on our broken system. We had the quote by that night. We made the decision to go with Coolpro and our new system was installed 2 days later. The guys who did the install were professional, polite, neat and hardworking. I would definitely recommend this company!
