I called Conditioned Air on 5/18 with a problem with my air conditioning. The repair technician came out and was very helpful, but told me that my 20 year old system was on it's last legs right before it was to get really hot in north Georgia! Trey followed up the very next day, came to the house and quoted a new system. Gulp. I was worried about receiving and having it installed with all of the supply issues we're hearing about and knowing it was soon going to be terribly hot and humid. Keith Lawrnece and his partner Zeke came out on 5/24 and did a complete install.

New Thermostat, furnace in the basement, a/c unit outside. They cleaned up after themselves, were careful with my hardwood floors, were on time and were very thorough in explaining the way the new system would work, showing me how to operate the thermostat, how to change the filters, everything. From the first repair technician to the final install, everything was smooth and professional.

They also installed a brand new "split" system in my basement last year and I've been very pleased with Conditioned Air Systems. Their people do a great job and are very good representatives of a trusted local company. I highly recommend Conditioned Air Systems and feel that I got a good value for my money.

Our technician (CWigington) and his partner showed up on time and completed our HVAC winter maintenance. After the maintenance, they pointed out hazardous build-up of mold/bacteria in our attic HVAC system. This was the first time this was brought to our attention. They were able to fully clean the system and install a Halo-LED purification system during the same visit.

Both were extremely courteous and professional during the visit. They advised on how we could get additional discounts and extend our Halo-LED system warranty. Thankfully (and unfortunately), they also notified us of captured rodents in our attic traps.

Our tech today was Nick Cuneo. He was very professional. Listened to our concerns and spent time working with my parents to understand the thermostat and review the system with them. They liked him so much that they want him to come out and do the bi-yearly servicing. Thank you for the prompt service response!

We lucked out when we got Clay as our Service Tech with Conditioned Air Systems! He was able to diagnose the problem, quote the repair cost, and drew my attention to an issue that might be causing air quality issues, with several remedies for it from least to most expensive. Most impressive was his ability to answer several technical questions while making it relatable to the average homeowner.

After already being without heat over the holidays (and 20 degree temps at night), Clay knew how important it was to get our system back up and running ASAP and not have to wait over the New Years holiday/weekend. He was able to take a service call towards Atlanta and went the extra step to pick up the Variable Fan Motor and Module himself personally (instead of waiting 2 days for it to ship).

He was back the next day and had our Heating System back up and running and professionally cleaned. From beginning to end, our experience with Clay was top notch and highly professional. We appreciate having Clay as our technician and Conditioned Air Systems to get us back up and running. We will be requesting Clay for any future service calls!

Conditioned Air Systems - CAS - just completed a total replacement of my Central AC and Heat equipment with a high efficiency Lennox system and Lennox iComfort S30 Ultra Smart touch pad thermostats. I am so glad I picked CAS - a local Gainesville, GA company where I live - which I had used a few years ago to install a Daikin mini split system. These folks are honest and they know what they are doing in an industry which seems to be full of inexperienced install techs and a lot of false advertising about "lifetime free service and parts".

Nothing of value can really be free. The cost is just hidden somewhere else! I understand that only 10% of HVAC Systems are installed correctly - so much for shopping for the lowest price! Everyone I worked with at CAS had 5 - 10 years or more of experience and gave me what I wanted - a problem solving install experience since I was living with a builder grade - get out quick - job during a major remodel 13 years ago.

During my install I had a team that included the Service Manager Jonathan, & Install Manager Tommy who made many changes in the location of the air handler and the routing of the ductwork. They made follow up calls to test and make minor adjustments. All of this started with My Sales/Comfort Specialist Trey Chesser who spent at least 2 hours giving me a complete problem diagnosis and three different levels of equipment to choose from to meet my budget. Trey has many years of experience and communicated with me every few days to make sure I was satisfied especially since we had to manage some equipment backorders. I will never use another HVAC outfit and have already made plans for CAS to manage my annual service contract.

Trey did an outstanding job of testing my home, explaining the pros and cons of all my options, and patiently answering all the questions I had. He was professional, very knowledgeable, and friendly. He did not pressure me in any way but gave me information to make an informed decision based on my home's needs and my budget. I would highly recommend speaking with Trey about your heating/cooling needs.

I was lucky enough to to be employed there for 5yrs and the experience and knowledge I gained from the heads of departments, supervisors and techs is vast. The amount of experience and knowledge they offer is massive. Which is matched by there dedication to customer service. If you are looking for any type of HVAC services from service calls to complete custom installs this the company to use. It may seem a little on the high side but you cannot put a price on piece of mind.
