Do these quick checks (2–5 minutes, no tools):
Book a tech if: breakers trip again, you smell burning, the outdoor unit won’t start while the indoor blower runs, ice returns, or your home isn’t cooling after 2–3 hours.
Arizona tip: Dust/pollen clog filters fast in summer—monthly checks help prevent freeze-ups.
Have this ready: photos of model/serial tags (indoor & outdoor), filter size, and a short video of the issue—this speeds diagnosis and quotes.
Safety: don’t open electrical panels or handle refrigerant—leave that to a licensed tech.
Diagnostic (service call) fee – This covers a licensed HVAC tech coming to your home, testing the system, and identifying the fault. In Arizona, shops commonly charge $79–$129 during regular hours and $129–$249 for 24/7 emergency calls. Many apply this fee as a credit toward the repair if you approve it on the spot—ask to see that line on the invoice.
Repair quotes – After diagnosis, you should receive a written, itemized estimate that includes:
Replacement / installation quotes (AC, heat pumps, or ductless mini-splits) should list:
Free estimate vs. paid diagnostic – “Free estimates” usually apply to equipment replacement. Repairs generally require a paid diagnostic first so the tech can test and quote accurately.
Pro tip: Get 2–3 written quotes and compare apples-to-apples (same SEER2, tonnage, scope, warranties). Always verify the contractor’s Arizona ROC license before approving work.
Note: Prices vary by brand, availability, and distance. Same-day and after-hours service may include an additional surcharge.
