Before you hire

Hiring heating or air conditioning help

Compare the diagnostic visit, repair options and installation scope with the equipment you already have.

Prepare a clear description

  1. Describe what the system does and when the symptom occurs, rather than guessing which part failed.
  2. Find the make and model from an accessible label or your paperwork, without opening equipment.
  3. Explain whether the system serves one room or the whole property and where the equipment is located.
  4. Say whether you want diagnosis, routine maintenance or a quote for replacement.

Questions to ask

  • Do you service this type and brand of equipment?
  • What is included in the diagnostic or maintenance visit?
  • Can you explain repair and replacement options in writing before I decide?
  • For replacement, what equipment, installation work, permits and inspections are included?
  • What parts and labor warranties apply, and who handles follow-up?

What can affect the price?

These factors help explain an estimate. Ask businesses to quote the same scope; LA Services does not provide a local price estimate.

  • The type, condition and accessibility of the existing equipment.
  • Diagnostic time, required parts and parts availability.
  • Any agreed duct, electrical or other related installation work.
  • Removal of old equipment, permits and included follow-up.
