"No findings, no solution, no explanation… collected the fee… the issue is still there. I had Triad Mechanical Company for our HVAC issue that the outdoor unit is not running. I told Paul, the assigned technician, that we had tried resetting the power to the outdoor unit but that only brought the unit back on running for a few days before it stopped running again. I asked Paul’s help diagnose the issue for the root cause. However, when I came to the property just a few minutes later than Paul, he told me that he had done his work already, well, by simply resetting the power to the unit! (although I told him that we already tried that but it didn’t work!)… He didn’t have the patience to explain to me what diagnosis he had done (within that a few minutes) and he didn’t even bother to come off his truck to show me but saying “go ask your tenant”. He collected the fee and left. I will never trust nor use Triad Mechanical Company again!"

"I highly recommend Julio. He re-stained and re-sealed my wood front door. This took multiple trips to my house to put on mulitple coats and he showed up everytime, also keeping in touch about precise estimated time of arrival. He also did excellent work, with attention to detail and ensuring that he didn't damage anything else in the process. Very nice to work with and professional. Will hire again. Before and after photos attached. Any unevenness in the stain is due to nature of the wood itself; he balanced out the absorption of stain very well compared to the original stain on the door."

Family owned since 1989, Bardi is rated A+ by the Better Business Bureau, was awarded Business of the Year in 2013 by the Gwinnett Chamber and received Best Customer Service by the BBB. Bardi is heavily involved with the community and offers free electronics pick-up and recycling during service calls to benefit Nobis Works, a nonprofit that supports people with disabilities seeking to join the workforce.

"I requested a HVAC tech come out to my home as my AC was not working properly. The tech recommended that I get a new AC. He told me he would have his sales rep come out to talk to me about the options I would have as far as replacing it. Their sales rep showed up. His name is Jimmy, and he told me all these great things about Bardi and their products. We came to an agreement of my buying a cheap HVAC system as I was trying to save money. It would cost me 12,000 dollars for the system. The next day April 5th, 2025 their install tech came out and installed the equipment. I was at work at the time, but I had a family member there. I returned home to find out the lower level of my home was not being cooled, and they had left part of my old HVAC system connected to the new system. It was a burnt up disconnect that should have been replaced and was a major part of what was wrong with my old system. Also they used a panel cover from my old system instead of new. I asked Jimmy to come and pick up the equipment which it states I have three days to reject the equipment in the contract. He expressed that I couldn't reject the equipment after it was installed. They had a tech come out the next day April 6, 2025 to fix the downstairs not working, and he fixed it. The next day it happened to be cold outside so I turned on the heat. No heat was coming out of the vents just cool air and the fan unit was running extremely loud outside. It was so loud it sounded like the fan unit was in my room on the second floor, so I turned it off. When I did turn off the fan unit made a horrible exploding noise. Once again I called Bardi and asked them to come get their HVAC system, they refused. Crystal the customer care rep is who I spoke with. She scheduled another repair tech to come out on April 12th to look at the HVAC system. I waited the entire day and no one showed up. I finally called and the receptionist told me it was their employee appreciation day no one would be coming. Monday I received a call from Crystal their customer care rep stating she text me and told me no one would be coming, but I never received that text. She scheduled another appointment for Easter Sunday. I stayed home Easter Sunday instead of going to church, and no one showed up again. I've stated each and every time I've spoken with someone from Bardi that I don't want to do business with them but they are basically trying to force me to keep their equipment at this point. This is by far the worst customer service experience I've ever had. These people are trying to rip their customers off basically. This should be illegal. I've reach out to get a lawyer to force them to remove their equipment from my home. Stay away from these people at all cost."

Heating and Air Conditioning questions, answered by experts

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

Signs that your air conditioner capacitor is malfunctioning include a smell or smoke coming from the unit, a humming or banging noise when it starts, the system shutting off randomly, higher energy bills, and no cold air blowing out of the unit. Additionally, if your capacitor is bad, the air conditioner may not turn on at all. 

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.
