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.

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.

I was out of the state when my son texted about the water leak in the basement. Althoff responded promptly and resolved the issue. So happy with the service they provide!

Laura Frayn

My A/C stopped working due to an unusual problem. Edwin used excellent analytical skills to find the solution. He was professional, thorough, and an excellent communicator. I highly recommend Edwin and Althoff

Greg Vachon

We had new a/c compressor and attic fan unit installed in the spring. Team was efficient and did a great job. Completed just as stated. Electricity bill went from above average for neighbors to below average according to ComEd report. It has been a lot of savings (plus house is cool - old one wasn't working well). Technicians have been wonderful in ensuring working just right (Ryan Staral, thanks! ... Brian Pulaski, thanks!). The staff calling us for our maintenance check (free with install) were so polite and accommodating. Really stellar service!

Jon at Althoff was a lifesaver. Had a leak that several other companies were unable to fix. Jon had a great attitude and resolved my problem quickly. I will be using Althoff in the future.

Yesterday we had our furnace, air conditioning unit, air filter system and whole house humidifier replaced. Alex Florita and Wiktor Kruzel were the two technicians who removed the old equipment and installed the new products. To say the installation was flawless, incredibly clean and perfectly done would be a gross understatement. These craftsmen did a fantastic job, were very careful in our home and answered all of our questions completely. We , as usual with Althoff, were totally satisfied. Today, Jesse Hernandez from Althoff came to us to replace our water heater. He was incredible. He was friendly, professional, and went way beyond my expectations. He answered every one of our questions, provided us with advice on how to best use the equipment and did an outstanding installation of our new tankless water heater. We have been customers of Althoff Home Services for over thirty years Over that time we have worked with many technicians and staff members to address our needs. I can say, without reservation, that all of these people met or exceeded our expectations. Jesse, Alex and Wiktor FAR exceeded those expectations. Jesse is an incredible technician. And what a truly nice person. Totally outstanding in every way. Bob and Sharon Rozycki

Brian was our tech at my dad's place. He did an HVAC checkup. My 99 yr old dad wanted to go to the basement with Brian so she could see what Brian recommended. He took the time to explain everything to dad, which I thought was so nice, given the fact it took dad awhile to get down the stairs! Great service.

Super responsive, communicative, informative, friendly, competitive and got the job done well. Highly recommended.

We are so pleased with the work Victor and Braden did-- professional, friendly, fast, and with great explanations. We could not be happier with their work, as we always are with your company's work. The Daikin unit is working perfectly, keeping our open concept kitchen, family room, music room, and dining room a uniform, warm temperature. THANKS!!!
