Power Strips Aren’t Enough Protection!

Many homeowners assume that plugging their electronics into a power strip is enough to guard against surges, but that’s a dangerous misconception. Most power strips only offer minimal surge suppression and aren’t built to handle major spikes caused by lightning strikes, grid issues, or large appliance cycling. At Althoff Home Services, we’ve seen firsthand how relying on these low-cost devices can lead to thousands of dollars in damage to computers, TVs, appliances, and HVAC systems.

The truth is, your home’s most expensive and sensitive electronics need protection at the source, your electrical panel. That’s why we recommend whole-house surge protection systems. These are professionally installed devices that stop surges before they travel through your wiring and into your home. If you live in Crystal Lake or the surrounding suburbs, trust Althoff Home Services to help you go beyond plug-in strips with a reliable solution built for today’s power-hungry homes.

How Whole-House Surge Protection Defends Your Home

Whole-house surge protection works by intercepting excess voltage at your main electrical panel, redirecting the surge safely away from your home’s circuits. It’s a vital layer of defense that protects every outlet, appliance, and device, whether it’s your refrigerator, smart thermostat, or home office equipment. At Althoff Home Services, we install high-quality surge protectors that offer protection from both external surges (like lightning strikes) and internal surges caused by appliances switching on and off.

These systems are especially important in areas like Crystal Lake, where seasonal storms and utility fluctuations can create sudden spikes in electrical current. Unlike plug-in devices that protect a single item, whole-house surge protectors shield your entire electrical system, reducing the risk of damage and helping extend the lifespan of your electronics. Our licensed electricians will help you choose the right system based on your home’s needs and install it to code for lasting peace of mind.

Let Our Electricians Wire You for the Best Surge Protection

Installing whole-house surge protection isn’t a DIY job, it requires a deep understanding of your home’s electrical panel and the proper integration of surge protection devices. At Althoff Home Services, our licensed electricians are trained to install these systems safely, efficiently, and in full compliance with local codes. We evaluate your home’s setup and electrical usage to recommend a surge protection solution that offers the best defense without overloading your system.

We’ve been family owned since 1961, and we proudly provide quotes before performing service so there are never surprises. Our work is backed by a 100% satisfaction guarantee, ensuring you feel confident in your investment. Protect your home’s power and valuable electronics the smart way, contact Althoff Home Services today to schedule your surge protection consultation.

We were very pleased with his professionalism. This service is included in our annual membership.

Althoff has helped us with our boiler system as well as our AC unit. They have repaired old units we had and even installed new ones when we needed. Everyone we worked with was kind, professional, and knowledgeable about the products.
Had difficult bulbs to replace and find they did it a short period of time and the installation was flawless

Matthew was such a pleasure to work with. He explained everything in layperson terms. Which I appreciated because I was extremely stressed out from the whole issue at hand. He gave me several different options to deal with the water damage and diagnose the source of the problem. of the leak. In conclusion, I would and will go to Altoff for all my future plumbing needs.

I recently switched to Altoff Services to do my annual A/C and Heater maintenance. They came this week to do the A/C. they did a thorough job in testing my A/C's cooling efficiency. they tested refrigerant levels.They removed the outside unit's shroud and thoroughly cleaned the unit. This was the first time anyone did that. I was very happy with the work they did.

We use Althoff Home Services for almost all of our HVAC, Plumbing, and Electrical needs. Pros: - It is easy to schedule an appointment with them. If you are a member of their White Glove Club, you get priority scheduling. - They spend time explaining the work they perform and any recommendations they have. - Their pricing is transparent. Everything is quoted and sent via email, so you know what you are paying every time they come to your house. - Their employees do not work on commission, so there are no high-pressure sales tactics unlike some of their competitors. Cons: - Some of their services are a little expensive. I would hire a handyman to do things like re-seat a toilet or replace a faucet in lieu of hiring of one of their professional plumbers. - They charge to come out to your house to give pricing estimates, but will deduct this from your bill should you choose to use them. I highly recommend Althoff’s and their team of professional staff!
