"I called Varsity on a Sunday night when I realized I had no hot water . It was the day we had the snow storm. The next morning Sean arrived to access the issue with my very old hot water heater. He was extremely knowledgeable and gave me my options. Within a short time Jake and Anthony joined and my new water heater was installed and working. No mess , no stress. They were amazing. Sean even shoveled the skirt of my driveway when the plows came and blocked me in as I was trying to get to work. This team went above and beyond to help any way they could. My utility room look clean and the work done right. I highly recommend Varsity. I feel comfortable knowing the technicians had the right training and were really nice guys to deal with. Thanks to Erica for taking my call so late and to Christine for getting the men out so quickly the next morning. They kept me informed every step of the way. I appreciated that."

"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."

"He showed up on time and gave a free estimate. 2 days later as planned, he showed up on time. The work was done professionally at the agreed price. I had a sink and faucet replaced, he also replaced the 2 shut offs under the sink."

"We contacted Berardi Electricals through Angi, and Leo reached out to us right away.Leo came to our house within an hour, quickly identified the issue as water damage to the main electrical box, and explained that it was an emergency situation. He returned the following week, exactly as discussed, despite bad weather, and efficiently moved the box, repaired the wiring, and provided temporary electricity until the next day. His work was exceptionally clean, efficient, and thorough, and he took the time to give us the right advice, possibly saving us from an electrical fire. We found him to be honest, knowledgeable, and true to his word. We would highly recommend Berardi Electricals to anyone looking for a trustworthy electrical work."
