"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."

"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."

Heating and Air Conditioning questions, answered by experts

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

Not necessarily. Some portable air conditioners may be vented out a door, wall, or ceiling—or even into another room. It’s not necessarily dangerous to run a portable air conditioner without venting it, but it is counterproductive since the unit needs to vent the heat in order to cool the room down in the first place. Without venting your portable AC unit, you’re essentially running a dehumidifier and increasing the temperature in the room. 

Mini-split air conditioners are less expensive to run than central air and are considerably more energy efficient. You can run the heating or cooling units in individual rooms and turn off the units in the rooms you aren’t using. This method allows you to save about 30% off your energy bill compared to a ducted system.
