"I had a great experience with Nate. He was extremely knowledgeable about A/C systems and was far more well-versed than many other companies in the area. He took the time to explain everything clearly, answer my questions, and make sure I understood the issue and solution. Nate was also very friendly, professional, and informative throughout the entire visit. I truly appreciated his expertise and excellent customer service. I would highly recommend Nate to anyone needing HVAC service."

"Extremely professional and responsive. Clearly understood value of a potential repeat customer. From project bid, thru execution and installation i found Chesapeake Comfort Systems to be the best contractor a home owner could ever hope for. It is clear they want your business and respect your time and home. Clearly walked thru options to tailor HVAC solution to a budget. I am a veteran home owner and renter who has had a bellyful of home contracting experiences from around the world. Chesapeake is first class and the best I have ever dealt with. I cant say enough good things about our experience to date. We have even signed on for a 4 year service plan and already recommended to many neighbors. Definitely got my money s worth and then some... nuff said."

"Mark from Duke's Electrical Services was recommended by a friend in the home improvement business whose referrals have always been A+, and Mark certainly lived up to that reputation. Mark and his son were professional, punctual, and communicative. They texted before arriving and showed up exactly on time. Mark performed a thorough electrical inspection, took photos, and reviewed everything with me so I understood the condition of our system. I also asked about a few smaller projects, including a dock light switch and a deck remote-control switch that weren't working. Mark followed through on his promise to return, contacted me within a week, and scheduled the repairs. During that visit, I added two more switch replacements, and they completed all three jobs in under an hour. What impressed me most was their attention to detail. After finishing, they vacuumed the work area. As someone who appreciates cleanliness, that meant a lot. Professional, efficient, cleanliness, very rare find."

Customers say: Quality work
"Lightning damaged several of the electronics in our house. I scheduled for an electrician to come out today and Dave was here, on time. He is professional and friendly...and he like dogs! Dave quickly and efficiently diagnosed each problem and was able to repair some items and give us direction for non-electrical repairs, such as HVAC and plumbing. Next time we need an electrical service, I guarantee it will be Gunther’s Electric!"
