During Your Visit

Here's how we check it.

  • Start with What You've Noticed

    We ask when the problem started, what the system is doing and whether anything has changed.

  • Test the System

    We test the parts linked to the problem. Depending on the system, this can include electrical connections, airflow, thermostat response, safety controls and refrigerant checks on cooling or heat pump equipment.

  • Explain What We Found

    We walk you through the cause in plain language and answer your questions.

  • Discuss the Next Step

    We explain the recommended work and price. You decide whether to approve the repair.

Common Questions

Before we check your system.

Here's what customers often ask about a diagnostic visit.

What is an HVAC diagnostic?

It's a visit to find out why your heating or cooling system isn't working as it should. We inspect and test the system, explain the cause and discuss what needs to happen next.

How much does a diagnostic visit cost?

Contact us for current diagnostic pricing. Tell us what type of system you have and what it's doing so we can explain what to expect when booking.

Is the repair included?

Diagnosis and repairs are separate parts of the service. If we find something that needs fixing, we explain the repair and price before you approve it. Ask about diagnostic charges when you book.

How long does the visit take?

It depends on the system and the problem. Some issues are easier to find than others. We keep you informed if more testing is needed.

What should I tell the technician?

Let us know when the problem started, which rooms are affected and whether you've noticed noises, fault codes or changes in airflow. Tell us what you've already checked, too.

Is this different from a tune-up?

Yes. Diagnostics focus on finding the cause of a problem. A tune-up is routine care for your system. Visit our HVAC maintenance page if you're looking to book seasonal service.

Do you serve areas outside Colorado Springs?

Yes. We also serve nearby communities including Fountain, Falcon and Peyton. Contact us to check service at your address.

Can I call about an urgent heating or cooling problem?

Yes. We offer 24/7 emergency HVAC service. Call with the symptoms and your location to confirm the next available appointment.
