"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."

We are local construction company specialize in roofing and general construction; siding, painting, design, build and remodel. You can contact us with any construction questions you may have. We will respond with honesty and most sincere way. Thank you

"PLEASE READ: Mark was great to work with in the beginning. After I did calculations for some items, Mark became angry and stopped communicating. Before construction could continue, I needed to get an electrician out because there was a real issue. Mark insisted there wasn't. After I insisted and called him out on his lack of communication, he said he was sending over his electrician the next morning. I cancelled plans and stayed home to wait on electrician. I never heard from Mark and he did not respond to texts. I called and he said there was nothing wrong and a new switch was installed. I called an electrician. There was an issue and the new switch was not installed. We also agreed that I would pay for flooring materials on main floor(lvp and underlayment) and Mark would demo and level kitchen and provide transition and baseboard. The floor is sloped in an area and there is a random square board and cuts in wood in more than one area. Mark used my old cheap laminate as a transition board on the stairs. This is not a joke or exaggeration. In addition, Mark did not use the underlayment that I purchased at his recommendation. Mark’s company cut and painted flooring on my gray stained covered porch without putting anything down. I have this on blink video occurring all day. There was paint and dust all over the porch. Mark does not apologize ever. The area had sharp small nails on stairs that were not even worked on. Mark said my request to correct this is ridiculous and said he would not repair slope. I’ve given him every opportunity to repair. I asked for an additional contract so we could let the contract guide us instead. Mark refused to add repairing of slope area and ignores me about underlayment. I asked him not to continue work or send his guys back for other work(He is doing insurance work on bottom floor.) Mark sent his guys twice after this and they just came into the house. I sent them home on Labor Day and texted Mark that I explicitly asked him not to be on the property until we had a signed agreement. His response was they could just work in garage. Update: 9/9/24! Mark is now demanding I take the reviews down or he won’t repair floors. The nightmare continues. He said he is putting a lien on my house. He says I am preventing him from doing the work but that is a complete lie. Read all details above to understand."

Water Heaters questions, answered by experts

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

Electric water heaters use a high amount of electricity, so they’re best for homeowners who subsidize their electric bill with solar or who live in an area with inexpensive electricity. For others, gas water heaters versus electric water heaters may be the more cost-effective solution, with the added bonus of heating water quickly and efficiently. No matter which you choose, you can lower your water temperature as low as possible to keep costs down.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it’s actually a silent threat to plumbing.
