"I sent a message to the company in the late evening regarding my broken central AC and Jason was here Tuesday morning to look at it. He tried to repair it but was not able to due to the age of the unit and the damage. We needed a new unit and he was here to put it in first thing Wednesday morning. Took him two hours and our AC was working. He was nice and professional. We felt the price was reasonable. Would use him again and recommend his business."

"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."

"I hired the SP and bought a heater/air conditioner and I paid him $500 deposit. He wired the garage after I paid him $650. He has not delivered the heater/ac unit. He did not wire the 240 volt line into garage. The track lighting and one outlet do not work. He stated he would come back on 2 different times and never did. He will not return calls or texts. He never put the cover on the outside outlet either."

"Handy Hubby Steve repaired cement stairs and installed a new outside back door. He did an awesome job. Steve was always on time and made sure everything was done properly. His prices were very reasonable. Great personality. Very personable. I will definitely use him in the future for any other repairs I need done."
