What Our Clients Are Saying About Us
Our tankless water heater stopped working right before Christmas leaving us with not only no hot water, but not even water to do laundry or run the dish washer.
So finding a good plumber, you can rely on, is different than finding a good plumber. When my family needed a plumber recently, LHR handled our call.
LHR got my service scheduled immediately for 2 days out from the day I called. Cody, the technician, showed up on time and was professional.
This is a completely professional organization start-to-finish. From my first phone call through the service to the follow-up, the LHR team treated me with kindness.
Cold call (literally!) from Hot Water Heater Manufacturer website. No prior relationship with them. No problem. Came same day. Tech friendly and knowledgeable.
Power surges are one of the most common and least visible threats to a modern home’s electrical system. Most homeowners think of surges only when a storm rolls through, but the majority of damaging surges originate inside the home itself, from appliances cycling on and off, HVAC systems starting up, or voltage fluctuations from the utility grid.
LHR Plumbing, Heating & Air installs whole house surge protectors for Manchester homeowners. A single device installed at your panel protects every circuit in the house at once, without requiring power strips or individual outlet protectors in every room. It’s one of the most cost-effective upgrades you can make to protect the investment you’ve made in your home’s electronics and appliances.
See What Happens During a Power Surge
Power surges don’t announce themselves. Most are small, everyday events caused by appliances cycling, HVAC equipment starting up, or fluctuations from the utility grid. They are rarely cause by the dramatic lightning strikes homeowners tend to picture. Over time, these smaller transients wear down the sensitive circuitry in modern electronics and appliances just as much as one large event.
A whole house surge protector installs at the electrical panel and monitors incoming voltage across every circuit, diverting excess energy safely to ground before it ever reaches your home’s wiring. It’s a single device that covers hardwired appliances and HVAC equipment that plug-in power strips can’t reach, built to current UL 1449 standards and designed to work quietly in the background with no maintenance required.
Protect your home’s electronics and appliances before the next surge hits. Schedule your whole house surge protector installation with LHR today.
How a Whole House Surge Protector Works
A whole house surge protector installs directly at your electrical panel and monitors the incoming voltage on every circuit. When it detects a spike above a safe threshold, it diverts the excess energy away from your wiring and into the ground before it can reach your appliances, electronics, or HVAC equipment.
Unlike plug-in power strips, a panel-level device covers your entire home simultaneously, including hardwired appliances like your furnace, air conditioner, water heater, and refrigerator that are never plugged into a power strip. It also handles surge events that enter through your utility connection, which can be far larger than anything a strip-style protector is rated to handle.
The installation is straightforward for a licensed electrician and is typically completed in under two hours. Once installed, the device works in the background without any maintenance or attention required from the homeowner.
What Your Home Stands to Lose Without One
The cost of surge damage adds up quickly. A single significant surge event can damage or destroy televisions, computers, smart appliances, HVAC control boards, and other electronics throughout the home simultaneously. Replacing these items costs far more than the device that would have protected them.
Manchester’s climate and older housing stock create specific surge exposure. New Hampshire sees regular thunderstorm activity in summer and ice storms in winter, both of which can cause utility-side surges. Many Manchester homes also have aging wiring that is more susceptible to voltage irregularities than newer systems.
HVAC systems are among the most expensive items a surge can damage. Modern furnaces, heat pumps, and air conditioners rely on sensitive control boards that are vulnerable to voltage spikes. A whole house surge protector is one of the most direct ways to extend the life of HVAC equipment and avoid repair bills that can run into the hundreds or thousands of dollars.
Our Whole House Surge Protector Installation Process
When you schedule with LHR, a certified technician arrives ready to assess your panel and complete the installation in a single visit. The first step is a review of your existing panel to confirm the installation location and verify the panel is in suitable condition.
After confirming the setup, you’ll receive upfront pricing before any work begins. The technician installs the surge protection device at the panel, connects it to the grounding system, and tests it to confirm it’s operating correctly. Most installations are completed within one to two hours.
LHR only installs devices that meet UL 1449 standards, the industry benchmark for surge protection equipment. After installation, your technician walks you through what was installed and what it protects. Schedule your installation today.
