Why HVAC Maintenance Matters
A well-maintained HVAC system lasts 15–20 years and runs more efficiently. Neglected systems break down during heat waves and cold snaps — exactly when you need them most.
Required Certifications
All HVAC technicians who handle refrigerants must hold an EPA Section 608 certification. Look for technicians who are also NATE-certified (North American Technician Excellence) — the industry's leading credential.
Common HVAC Services and Costs
- Annual tune-up/maintenance: $75–$200
- AC repair: $150–$500+
- Furnace repair: $150–$500+
- AC unit replacement: $3,000–$7,000
- Furnace replacement: $2,500–$6,000
- Ductwork cleaning: $300–$700
Spring and Fall Are Best
Schedule maintenance in spring (before cooling season) and fall (before heating season). Technicians are less busy, pricing is better, and you're not competing for emergency appointments.
What to Ask
- Are you EPA 608 and NATE certified?
- Do you offer maintenance plans?
- What brands do you service?
- Is there a diagnostic fee, and is it applied to the repair if I proceed?
- What warranty do you offer on parts and labor?
Emergency vs. Scheduled Service
Emergency HVAC calls typically run $150–$300 extra. If your system is struggling in mild weather, schedule service now rather than waiting for a breakdown in extreme conditions.
