A tune-up or maintenance visit takes 1–2 hours. Equipment replacement (AC, furnace, or heat pump) is typically a full day — 4–8 hours. Multi-zone or ductwork projects can run 2–5 days.
Ask for their state license number and proof of insurance, a written itemized estimate, whether they pull permits for equipment replacements, and their response time for emergency calls. Reputable contractors answer these without hesitation.
Every listing is sourced from Google Business Profiles and ranked by real Google ratings and review counts — no pay-to-rank. We display each contractor's Google rating and review volume so you can compare track records before calling. Always confirm licensing and insurance directly before work begins.
Start by contacting the contractor directly — most reputable companies will return to fix issues at no charge. If that fails, file a complaint with your state contractor licensing board and leave an honest Google review. You can also dispute charges with your credit card issuer if work was paid and not completed as agreed.
