Owner on Every Job
This is what truly sets Apex apart. Ed Miller, the owner, personally handles every service call, installation, and repair. You're not getting a rotating cast of technicians with varying experience levels. You get the owner's expertise, accountability, and commitment to quality on every single job. This means consistent service, direct communication, and the peace of mind that comes from working with someone who has a personal stake in your satisfaction.

As a veteran-owned business serving Porter County, we understand the values of integrity, reliability, and service. We're part of the community we serve. Your satisfaction isn't just about business reputation - it's about doing right by our neighbors.


No Quotas, No Pressure Sales
Unlike corporate HVAC companies where technicians have sales quotas to meet, we operate independently. Ed doesn't push unnecessary equipment or recommend replacement when repair will do.

This approach has earned us a perfect 5.0-star rating.

We offer true 24/7 emergency service, not just an answering service. When you call our emergency line, you reach Ed directly. He responds personally to urgent situations, typically arriving within an hour for local emergency calls. No waiting until Monday morning. No impersonal dispatching system.

Your HVAC Questions Answered

Frequently Asked Questions

  • How quickly can you respond to HVAC emergencies?

    For true emergencies like complete heating failure in winter or AC breakdown during extreme heat, Ed typically responds within an hour for local calls. We offer genuine 24/7 emergency service, including nights, weekends, and holidays. 

  • What HVAC brands do you service?

    We service and repair all major HVAC brands, including Carrier, Trane, Lennox, Rheem, Goodman, Bryant, York, Amana, American Standard, and many others. It doesn't matter if we installed your system or not - if it's broken, we can fix it.
  • Do you offer financing for HVAC installations?

    Yes, we can connect you with financing partners who offer flexible payment options for new furnace and AC installations. This allows you to get the comfort your home needs today and manage payments over time.
  • How do I know if I need repair or replacement?

    Ed provides honest assessments without pressure. Generally, if your system is under 10 years old and repair costs are less than half the replacement cost, repair makes sense. For systems over 15 years old with major component failures, replacement is often more cost-effective long-term. We'll explain your options clearly and let you make the best decision for your home and budget.

  • Why should I choose Apex over other HVAC companies?

    The owner-on-every-job guarantee is our biggest differentiator. You're not dealing with a different technician each time. Ed personally handles every service call, bringing over a decade of experience to your home. Combined with our veteran-owned values and no-pressure approach, we deliver a level of personal service and accountability that larger companies simply can't match.
