If you’ve ever endured an extended power outage, the thought of upgrading or installing a whole-house generator has likely crossed your mind. Our licensed Chicago electricians specialize in generator replacement and installation, assuring your home stays powered with a reliable, high-quality system. If your generator struggles to start automatically, delivers inconsistent power, or requires frequent repairs, upgrading to a more reliable and efficient model may be the best option. A noticeable increase in fuel consumption can also signal inefficiency. Additionally, if your unit is older than 20 years or hasn’t been properly maintained, you may want to bypass home generator repair and instead consider generator replacement.

The last thing you want during a power outage is to discover your whole-house generator isn’t working properly. Regular testing can help identify issues early, but certain warning signs indicate it’s time to call for generator repair services. Visible damage, leaks, diagnostic alerts, inconsistent power output, or unusual noises and odors all suggest potential problems. If your generator has gone unused for months or hasn’t received proper maintenance, it’s best to have it inspected. Don’t wait until an outage leaves you without backup power—Four Seasons’ expert generator service and repair team is ready to help.

You might be wondering: Why choose a whole-house generator over a portable generator? The advantages are clear:

• Most portable generators must be operated outside and in a covered area to protect them from the weather. For some Chicago homeowners, this means you’ll have to wait until inclement weather has passed before you can even begin using it. A whole-house generator starts automatically; no setup is required.
• Keeping gas on hand is a hassle, and having enough for extended power outages is even more inconvenient. Whole-house generators run on natural gas or propane, ensuring fuel is always available.
• Pulling out and starting a portable generator is a lot of work. A whole-house generator kicks on automatically.
• Portable generators are extremely loud, and many Chicago homeowners get complaints from neighbors when running them. Quality whole-house generators are much quieter.
• A portable generator only powers a few small appliances, while a whole-house generator keeps your Chicago home powered as if nothing happened.
