"Terrible customer service He created giant messes and lied to me on multiple occasions. I will say anything to get the project and not actually answer questions. When they came to give the quote, I asked them where they would put the heat pump and I said behind the house, but when they went to install it, it would not fit behind the house according to code. I constantly had to hound them to finish the job. They started in the spring, and then they did not finish until the winter, after saying they could start in 2 weeks. They left me without heat on below-freezing days because they were not finished. They did not honor parts of the contract. charged for service even though the contract says it is free for 3 years. They tried to charge me for things they did not install(humidifier). Installed the ventilation system over some sill rot. I left gaping holes in my home for months. I had to hound them every step of the way to get them to do the next part of the project. They were replacing propane and oil with gas and did not tell me I had to remove the propane to do so, and then the town would not permit their work and I had to pay out of pocket for more conversions. I had to hound them to get permits, including an oil tank removal permit, which they never pulled and I still do not have! The end result was an expensive system that I think is misconfigured and ill-fitting for my home (it does not remove humidity properly). If you would like to do the project management yourself, hire this company. That said, there was one very nice technician, but I would not have them install anything."

Generator repair services FAQs
Before hiring an electrician to work on a project in your home, verify their licensing, qualifications, and insurance. Check their official website, read customer reviews, and confirm their credentials with your local labor department. Ensure they hold liability insurance and have strong references. This thorough verification helps you receive reliable service and protects your home.
By bundling multiple electrical tasks, you can reduce overall costs by minimizing repeat service fees and consolidating labor charges into a single visit. By scheduling several repairs at once—like outlet replacements, light switch installations, and light fixture installations—you eliminate extra call-out costs and gain efficiency, securing better pricing without sacrificing quality.
Unless you're a licensed electrician, it's not safe to perform electrical work yourself. Handling electrical tasks without proper expertise poses serious risks like electric shock, fires, and structural damage. Professional electricians use specialized tools and follow strict codes to ensure the work is done safely and correctly, protecting your home and well-being.
