When to Call ChillTech

These are common signs that a residential HVAC system needs a professional diagnostic visit instead of another quick reset.

No heat in winter or no cooling during a heat wave

System will not start, trips breakers, or shuts off quickly

Burning smell, unusual noise, or water near equipment

Boiler lockout, low pressure, or circulation failure

What We Handle

Service scope

  • Urgent furnace, AC, and boiler diagnostics
  • Temporary stabilization when full repair needs parts
  • Repair versus replacement guidance for failed systems
  • Same-day dispatch when schedule and parts availability allow

How the visit works

  1. Gather symptoms by phone so the visit starts with the right information.
  2. Prioritize safety, power, fuel, airflow, and water issues first.
  3. Explain what can be repaired immediately and what needs parts or replacement.
  4. Confirm the system is safe to run before recommending next steps.
