The Alltech HVAC Difference
When your heating or cooling system breaks down, you don’t want a sales pitch — you want answers, honest advice, and reliable service. That’s where choosing a locally owned and operated HVAC company makes all the difference.
At Alltech HVAC, John and Joe have owned and operated the business since 2004. Based in Des Plaines, Illinois, they’ve built Alltech on a simple belief: focus on service, not sales. No corporate scripts. No commission-based pressure. Just experienced technicians doing what’s right for the customer.
The Problem with Corporate HVAC Companies
Over the past decade, the HVAC industry has seen a rise in large, corporate-owned service providers. While these companies often have flashy branding and aggressive advertising, the customer experience can suffer.
Common issues with corporate HVAC companies include:
- Commission-based technicians incentivized to upsell
- High-pressure sales tactics
- One-size-fits-all solutions
- Limited flexibility and personal accountability
- Technicians who answer to sales quotas instead of homeowners
When profits come first, homeowners and businesses often pay the price — literally.
The Advantage of a Locally Owned HVAC Company
Choosing a local HVAC contractor like Alltech means working with people who live in your community, understand the regional climate, and stand behind their work.
1. Service Comes First — Always
At Alltech, we specialize in providing service. That’s it.
Our technicians are not salespeople. They are skilled professionals trained to:
- Diagnose the real issue
- Explain your options clearly
- Recommend what actually makes sense for your home or business
Because we don’t pay commissions, there’s no pressure to replace a system that can be repaired safely and effectively.
2. Honest Recommendations, Not Sales Scripts
Corporate HVAC companies often rely on scripts and sales funnels. Local companies don’t.
At Alltech HVAC, every recommendation is based on:
- System condition
- Efficiency
- Safety
- Long-term reliability
If a repair makes sense, we’ll say so.
If replacement is the better option, we’ll explain why — plainly and honestly.
This no-nonsense approach is the foundation John and Joe have stood behind since 2004.
3. Experience You Can Trust
When you call Alltech, you’re not calling a call center in another state. You’re calling a local team with decades of hands-on experience.
John and Joe have:
- Owned and operated Alltech HVAC for over 20 years
- Built long-term relationships with customers across Chicagoland
- Created a culture of accountability, craftsmanship, and trust
Local ownership means decisions are made here, by people who care deeply about their reputation in the communities they serve.
4. Proudly Based in Des Plaines, Serving All of Chicagoland

Because we work in these neighborhoods every day, we understand:

That local knowledge allows us to provide faster, more accurate service — without guesswork or upselling.
5. Faster, More Personal Service
Being local means we can respond quickly and provide a more personal experience.
Our customers benefit from:
- Familiar technicians they recognize and trust
- Flexible scheduling

We don’t disappear after the job is done — we stand behind our work.
