“I have used Nero for multiple projects while working for myself as a General Contractor. You won’t find a cleaner more organized outfit. They truly exemplify professionalism. I’d recommend them for both big and small projects.”

“Possibly the finest experience I have ever had in 37 years of home ownership.  Mike Nero is polite, timely, knows his business cold and obviously enjoys his work.  The people who work for him are top notch.  Of the 8 contractors I solicited to install central air-conditioning Mike was hands down the best.  Our house, built in 1934 does not lend itself to an easy A/C install.  Mike and his crew developed a single air handler solution quickly.  He presented the contract in person and explained it in detail. I recommend Nero without reservation.”
