"I had a problem with my old landline phone system. First I called Verizon, but their technician could not solve the problem. Then I contacted CH Tel. Charlie called back promptly and sent a technician, Rick, the same day. Rick was very knowledgeable and thorough. He was able to find the problem and install a new line. While he was here he also solved some long-standing problems I had with loose wires and an open phone box. He was also very respectful of my property and did a good job cleaning up after the work.

"Outstanding Service from Technicians Dennis and David, Haas and Sons Electric!!! We hired Haas and Sons Electric at 8:30am on 12/15/25. They responded, scheduled and completed the work before 2PM the same day. Haas and Sons Electric addressed a wiring issue related to the doorbell / security camera. Dennis and David were exceptional! They called while enroute and arrived promptly as scheduled for the appointment. They immediately demonstrated high levels of professionalism and knowledge about our electrical issue: Dennis answered all our questions and patiently walked us through their diagnostic process. He also clearly explained the factors related to the wiring connection between the doorbell wiring by the builder (of the home) and the security camera equipment installation related to the root cause of the issue. The quality of work was superb. David replaced the doorbell system and all its necessary equipment components efficiently and ensured all new wiring was up to code, meticulously cleaning the work areas afterward. We appreciated their honest approach and made recommendations for future maintenance without any sales pressure.

Generator Install questions, answered by experts

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
