Twin State Agency is based in Spartanburg, SC. Founder Alvin Maxwell personally audited 50 Upstate HVAC websites in January 2026 to map exactly where small operators are losing jobs to bigger competitors. That research is the foundation of every system we build.

The Real Problem

It is not that you need more leads.
It is that the ones you have are slipping.

Most HVAC owners in Duncan are losing 2 to 3 jobs a week and never know it. The call went unanswered. The review was never requested. The slow season hit before the customer list was worked. That has to stop before the growth wave arrives, because once the 450 new homes are occupied and homeowners form their first contractor loyalties, the window to be first is gone.

"I miss calls when I'm on a job off Wade Hampton or out on Highway 290."

That call went to the next number on Google. In a small market like Duncan, losing one call means losing one of a limited number of jobs available that week. AllyResponse texts them back within minutes so the conversation starts before they move on.

"People in Duncan know my work but my Google profile doesn't show it."

Word-of-mouth works in a small town until a new homeowner moves in from Charlotte or Greenville and searches Google instead of asking a neighbor. AllyReview sends a review request right after every job closes so your reputation grows where new residents are actually looking.

"Slow season comes every year and I'm never ready for it."

AllyReturn reaches back into your existing Duncan customer list before the season turns and books maintenance calls and tune-ups before your competitors do. Your best next job is already in your database.

Why Duncan, SC Right Now

Duncan Is a Small Town on the Edge of a Big Growth Wave.

Duncan grew 19% since the 2020 census and is not done yet. More than 450 new homes are expected through 2029, driven by new industry arriving along the Highway 290 corridor between Spartanburg and Greenville. That is hundreds of families who will need HVAC service, have no established relationship with a local contractor, and will decide who to call based entirely on what they find on Google.

The contractor who builds a strong online presence now, before those homeowners arrive, has a first-mover advantage that is very hard to overcome once it is established. Tuck and Howell has been the incumbent name in Duncan since 1969. But 55 years of word-of-mouth does not automatically transfer to new residents who have never heard of them. That is a gap a well-positioned small operator can step into.

Local Market Snapshot — Duncan, SC

We looked at the HVAC Google Maps results for Duncan. Here is what the competitive landscape actually looks like.

Tuck and Howell is the dominant name in Duncan with over 1,200 five-star Google reviews built over more than 55 years in business. That is a deep lead. But they have expanded their operation significantly into Greenville, which means their attention and resources are no longer focused exclusively on the Duncan market the way they once were.

Below the top position, the Duncan Maps results are thin. Other local operators like Thompson Heating and Air and C.J. Compton Plumbing Heating and Air have limited online profiles and modest review counts. The 450-plus new homes coming through 2029 will bring homeowners who have never heard of any of these operators. A small shop that gets visible before they arrive, and responds fast when they call, will build a customer base that compounds for a decade.

"In Spartanburg, the bottom half of HVAC companies average just 8 Google reviews. The top 3 average 180-plus. In Duncan, Tuck and Howell holds the top position with 55 years of history behind them. But the 450 new homeowners arriving through 2029 do not know that history. They know Google, and whoever shows up first with the most recent reviews wins their first call."

How This Works

Three steps from your free report to an active system running in the background.

No six-month warm-up. No waiting to see how it goes. We move fast because you are already losing Duncan jobs every week you wait, and the growth wave is not waiting either.

Step 02

Walk Through the Growth Assessment

A short 20-question audit built for HVAC owners. It identifies which Ally systems will move the needle fastest for your specific shop and your position in the Duncan market right now. In a small market where 450-plus new homes are coming, getting the foundation right before that demand arrives is the entire game.

Step 03

We Build and Run It for You

No software to learn, no dashboards to manage. We set up the system, connect it to your existing workflow, and keep it running. You stay focused on the jobs. The system handles the rest.

Who This Is For

Built for the owner who runs the truck and the business in Duncan.

Twin State Agency works exclusively with HVAC contractors in Duncan and the Spartanburg County market. Owner-operated. Word-of-mouth dependent. Ready to build something more consistent before the next wave of growth arrives.

  • You are the owner and you answer the phone. Marketing has been an afterthought and you know it.
  • You have a solid reputation in Duncan built on word-of-mouth, and you want to be visible to the 450-plus new homeowners arriving along Highway 290 who have never heard of you.
  • You are watching Tuck and Howell hold the top Maps position with 55 years of reviews and want a system that closes that gap on recency, not history.
  • You want to be positioned before the new homeowners arrive, not scrambling to catch up after they have already called someone else.
  • You want a system you do not have to manage. Done for you, not a course or a template.
Who this is not for: If you are looking for someone to run paid ads without first fixing the systems that convert those ads into booked jobs, we are not the right fit. We will not spend your money on traffic until we know the foundation is solid.

Common Questions

HVAC Marketing Questions for Duncan Contractors

Everything a Duncan HVAC owner needs to know before spending a dollar on marketing.

How do I get more HVAC customers in Duncan without running ads?

The fastest path is fixing what is already leaking. Most Duncan HVAC owners rely on word-of-mouth, which works until it doesn't. Optimize your Google Business Profile with accurate hours, service areas, and recent photos. Then put a system in place that automatically requests a review after every job. When new homeowners arrive on Highway 290 and search for an HVAC contractor, the business with 50 recent reviews wins the call over the one with 8.

Is Duncan a competitive HVAC market for a small operator?

Duncan is a smaller market today, but that is changing fast. Established names like Tuck and Howell have been here since 1969 and carry strong local recognition. But new residents moving in from outside the area do not have that historical knowledge. They go to Google Maps. A small operator with a strong profile and recent reviews can be the first name those new homeowners see, ahead of contractors who have been here for decades.

Why should I invest in marketing now if Duncan is still a small town?

Because 450-plus new homes are coming through 2029 and the contractors who are already visible online when those homeowners arrive will own their business for 10 to 15 years. Marketing systems take time to build momentum. Starting now means you are established by the time the demand peaks. Starting after the growth arrives means competing against operators who got there first.

Do you serve Duncan specifically or just the Spartanburg area generally?

Twin State Agency works with HVAC contractors across the Upstate South Carolina market. If you are based in Duncan and run jobs into Lyman, Wellford, Reidville, or anywhere else in the Spartanburg District 5 area, we build the system around your actual service footprint and the specific competitors you face in each of those communities.

What does Twin State Agency actually do for a Duncan HVAC shop?

Six systems in the background. Review generation after every completed job. Missed call follow-up within minutes. Seasonal campaigns into your existing customer list. Local SEO and Google Business Profile management. Lead follow-up for prospects who went quiet. And a single inbox so every call, text, and message is in one place.

Every business we work with starts from a different place. Some have 10 reviews and a broken Google listing. Others have a solid reputation but are losing jobs to missed calls. What we build depends on where you are right now, and what you get out of it depends on factors we do not fully control, including your market, your pricing, how quickly your team responds to leads, and how the systems are maintained over time.

We will not promise you a specific number of jobs or a dollar figure. What we will do is show you exactly what we find in the audit, tell you what each fix is designed to do, and track the results honestly. If something is not working, we say so.
