We had a power outage for over 13 hrs which caused our on off switch to our electric water heater to burn out. I called Alliant Electric the woman on the phone told me to call an electrician! She said if it's Alliants fault they will reimburse me. Havent heard back from Alliant yet. I called Peck and Weiss Chad came out he was very professional it was a Saturday. Alliant electric guy worked from outside Chad inside.

The outside box would not turn off when switch was off. I get a bill for over $800 that said 4 and a half hrs labor for closing a burned out on off box and relocating wire to fuse box right next to on off switch! Chad left for awhile to go get a part! I was charged for the time he was gone! Ridiculous this is now 1/2019 No contact from Peck and Weiss. I will never use them againAlliant Electric did reimburse us but Peck and Weiss prices Outrageous!

Cory was very professionalism, courteous and knowledgeable for a young man. Any questions that I had, he was more than happy to take the time to explain them to me. Thank you for your service! Service: AC maintenance

I am writing this review to make sure I recognize the great work Peck and Weis has done for me with HVAC and Electrical services. Peck and Weis has assisted us with new construction commercial and with service at our residence. I have found them to be very responsive even during this unprecedented time of home sales expansion and building. More importantly to me, they have acted with integrity and squared away issues that weren't my responsibility.

Their fees for other services have been reasonable and I like that the Customer Service staff clearly gives you the option of immediate service which may require over time rates or they work to get you on the schedule as soon as possible. Thanks to everyone at Peck and Weis for working as a team to provide great service to this community.

We used Peck and Weiss this year for two very challenging and complex jobs at our home--one involving the A/C, and one involving the hot water heating systems. Both times, the Servicemen went entirely "above and beyond" to solve the problem -- and didn't present us with a massive bill at the end for any additional time it took, or for some of the smaller, add-on things they did as part of the project. Highly recommmended!
