"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.

The installers also were prompt, did an excellent installation, simulated a power outage, and showed my how to switch the whole house over to the generator. "

"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.

Generator Install questions, answered by experts

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
