Scott C.
We have just moved into our home and wanted to get our furnace checked out. It was extremely easy to schedule and they even had same day options. Bear came out for us and was prompt and on time, let me know when he was on his way, and was extremely polite and kind to our home. He had great recommendations and didn't try to upsell us on anything, just honest opinions for us in the future. We will definitely have Bear back!

Mr. Holycross, was very pleasant, informative & open to questions. I was grateful to get serviced so quickly this time of year. His service was neat, clean and efficient. His 21 years of experience truly showed especially with such a big job and was completed very quickly. Thank you Mr. Holycross & the entire Chris Holmes team that made it happen

I heard about Chisholm through federal and I’m glad I did. My experience with them is always fantastic and you can tell they keep a very high standard of their employees because they are always very friendly and professional. I would say their pricing is reasonable, however, I haven’t really shopped around for the jobs I’ve had them do for me. The service plan is nice to have so then all their routine inspections are covered. I would say working with them is very worth the money because of how much I trust the company and technicians to do a good job and treat me fair. They do upsell sometimes, but it is never pushy and super straightforward without pressuring.

I called to get my air duct checked because it was blowing not hot in my bathroom . Jordan "Bear" Lee came out, very professional, through, and friendly. I had the thermostat set on emergency heating, he corrected it to regular heating. He checked the air ducts in the attic, recommended at some point it needed some work. I purchased their service plan, twice a year they will come out and check . He was knowledgeable, professional and friendly. Great job Jordan "Bear" Lee. 😀

Signs You Need Whole House Generator Repair

A generator that isn’t working right usually gives you a few warning signs before it fails. Here’s what to watch for.

  • The generator won’t start.
  • Frequent stalling during use
  • Unusual noises or vibration
  • Warning lights or error codes
  • Fuel or oil leaks
  • Delayed power transfer
  • Rising repair costs

Why Invest in a Whole House Generator

A whole-house generator does more than keep the lights on. It automatically kicks in during an outage, so your HVAC system, refrigerator, well pump, and sump pump keep running without you lifting a finger. That matters in Greer, where summer thunderstorms and occasional winter ice can knock out power for hours or even days.

Beyond convenience, a generator protects your home from bigger problems. A sump pump without power can lead to a flooded basement or crawl space, and an HVAC system that shuts down during a heat wave can put stress on both your home and your family. A properly sized generator keeps your systems running smoothly and gives you peace of mind every time the forecast looks rough.

Our Generator Installation & Repair Process

We start every installation with a walkthrough of your home to determine the right generator size for your electrical load, family needs, and budget. From there, we handle the permitting, gas or propane connection, and electrical work required to safely tie the generator into your home’s system and ensure compliance with code.

Once installed, we test the automatic transfer switch and run the generator through a full cycle to confirm it operates as intended during a real outage. For repairs, we diagnose the issue first, walk you through what we find, and provide upfront pricing before any work begins. We service most generator brands and keep common parts on hand to get your system back up quickly.

Staying Powered Through Upstate Storms and Outages

Greer sees its share of severe summer thunderstorms, and the humidity that builds up in the warmer months puts extra strain on the power grid as everyone runs their AC at once. That combination often leads to short outages that can turn into bigger headaches if your home isn’t prepared. Winter brings its own risk, too, with occasional ice storms that can bring down lines and leave homes without heat for extended periods.

A whole-house generator gives you a buffer against both scenarios. Instead of scrambling for flashlights or worrying about your HVAC system during a heat wave, your home automatically switches to backup power. That reliability matters most when the weather is at its worst and getting a technician out quickly becomes harder for everyone.
