"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."

"The latest visit diagnosed a failed ignition valve which needed to be ordered and replaced. They arrived promptly, assessed, diagnosed and ordered the parts immediately. It only took a few days for the parts to arrive and they were able to schedule me in for the service call. The first technician was able to maintain the ignition valve until the new part was available, which was directly responsible for heating my home. The second technician installed the part and was able to assist me in some technical updates on the app and digital thermostats. I learned so much from Michael and appreciated his knowledge and patience. He also fixed a safety issue on the second level and adjusted the air flow for the system. The system sounds so much quieter. It was a warranty issue with no cost."

Gas Leak Repair questions, answered by experts

In North America, pipe measurements are listed as the nominal pipe size (NPS). This measurement refers to the outside diameter. As an example, a 1/2-inch copper pipe has an outside diameter of 5/8 of an inch. If a hardware store lists a pipe as having a 2 NPS, it means that all the pipes with this measurement have a 2 ⅜-inch outside diameter, regardless of wall thickness and inside diameter.

Most likely, a gas plumber would be the best pro for many components in your home, and you might not even realize it. Natural gas plumbers are responsible for maintaining and installing natural gas lines, including installing appliances that use natural gas. These can include:

  • Fireplaces

  • Water heaters

  • Furnaces

  • Hot tubs

  • Clothes dryers

  • Ovens

  • Outdoor grills

Gas plumbers are also the pros that would handle a natural gas leak in your home, so it's essential to know the signs of a gas leak before it becomes a dangerous situation.

Although a gas company supplies gas to homes, connecting gas appliances, like a dryer, is not their responsibility. The primary role of a gas company is to safely deliver gas to a property and maintain the gas supply lines up to a specific point, typically the gas meter or shut off valve. The task of installation is usually taken on by the homeowner or professional dryer installer. 

Appliances typically connected to a gas line include gas stoves, water heaters, furnaces, and gas fireplaces. Essentially, any appliance in your home that uses gas needs to be connected to a gas line, which connects your home with the main gas line owned and operated by your gas company.

In most cases, a flexible steel hose connects your gas line to the wall. This process is typical if you are replacing your gas stove or if the old pipe has worn down. However, always leave this job for a professional plumber. Errors can be very dangerous, so it's worth calling a professional to take a look.
