"Keep Smiling sent me Roy Wint and I'm very glad they did. Roy installed a replacement ceiling fan as well as four recessed lights. The result of the project is a much better lit and livable living room. I want to extend special kudos to Roy. He was very professional, polite, and friendly. A joy to have working on my home. He went out of his way to avoid creating any holes in the ceiling other than those housing the lighting fixtures. And he also did a safety inspection of my home's fuse box. I can't say enough good about this young man. I'll definitely be calling him the next time I need electrical work done in my home."

"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 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

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.
