"I recently had an electrical inspection done by TE Certified Electrical, Plumbing, Heating & Cooling, and I couldn’t be more impressed. From the moment the technician arrived, the experience was professional, thorough, and reassuring. They took the time to explain everything they found in a way that was easy to understand, and I felt confident I was in good hands. What stood out most was their attention to detail—they didn’t just check the basics, they inspected the entire system to ensure my home was safe and up to code. No high-pressure sales, just honest advice and helpful recommendations. I’ll absolutely be using TE Certified again and would highly recommend them to anyone looking for top-tier electrical service."

"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."

Water Heaters questions, answered by experts

Signs that your water heater needs replacing include rust or corrosion on the tank, persistent leaks, inconsistent heating, strange noises coming from the heater, decreased efficiency, and visible damage. Water heaters over 10 years old may also need to be replaced. However, in some cases, these issues can be fixed with a repair rather than a replacement, so make sure to consult a pro before investing in a new water heater.

The lifespan of your water heater depends on the type of water. For traditional water heaters, you can expect it to last between 8 and 12 years if gas or 10 to 15 years if electric. Tankless water heaters can last up to 20 years with proper maintenance. The total number of years you’ll get out of your water heater depends on the maintenance it receives and how much it’s used.

If you're replacing a broken water heater, now is a great time to make sure you're selecting a unit that has the right capacity for your household. According to the U.S. Department of Energy, a small 50-gallon to 60-gallon tank is sufficient for households with one to three people. A medium-sized 80-gallon tank is considered ideal for three to four people. A larger tank may be needed if your household has four to six people.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

Whether to repair or replace your water heater is determined by your water heater’s age and condition. If you have an older model reaching the end of its life expectancy or if your water heater has been having problems more frequently than usual, replacement might serve you better. If you’ve been thinking about upgrading to a tankless water heater, then you may not want to spend any further on repairing your old one, either.
