10-Step Hiring Checklist

Follow these steps before hiring any hvac technician.

  1. 1

    Verify HVAC licensing

    Most states require HVAC technicians to hold a specific license. Check your state's licensing board for active status and any disciplinary actions.

  2. 2

    Confirm EPA certification

    Technicians who handle refrigerants must hold EPA Section 608 certification. This is a federal requirement, not optional.

  3. 3

    Check insurance coverage

    Confirm general liability and workers' compensation insurance. HVAC work involves electrical systems, gas lines, and refrigerants.

  4. 4

    Get multiple quotes for installations

    For new system installations, get at least three quotes. Each should include a load calculation to properly size the system for your home.

  5. 5

    Ask about energy efficiency ratings

    A good HVAC contractor will discuss SEER ratings, AFUE ratings, and help you choose a system that balances upfront cost with long-term savings.

  6. 6

    Check manufacturer partnerships

    Authorized dealers for brands like Carrier, Trane, or Lennox receive specialized training and can offer extended warranties.

  7. 7

    Read reviews focused on maintenance

    Look for reviews that mention thorough inspections, honest diagnoses, and fair pricing. Avoid companies known for upselling unnecessary repairs.

  8. 8

    Ask about maintenance plans

    Many HVAC companies offer annual maintenance plans that include tune-ups and priority service. Compare what is included before signing up.

  9. 9

    Confirm they do a load calculation

    For new installations, a Manual J load calculation is essential. An oversized or undersized system wastes energy and shortens equipment life.

  10. 10

    Get a written agreement

    The agreement should cover equipment specifications, installation details, timeline, total cost, payment schedule, and warranty information.

Frequently Asked Questions

How much does a new HVAC system cost?
A new central air conditioning and heating system typically costs $3,000 to $12,000 installed, depending on the system type, brand, efficiency rating, and home size. High-efficiency systems and heat pumps can run $7,000 to $15,000. Many homeowners qualify for federal tax credits or utility rebates that offset the cost.
How often should HVAC be serviced?
HVAC systems should be professionally serviced twice a year: once in spring for the cooling system and once in fall for the heating system. Regular maintenance extends equipment life, improves efficiency, and catches small problems before they become expensive repairs.
What is a good SEER rating?
The minimum SEER rating for new air conditioners is 14-15 depending on your region. A SEER rating of 16 or higher is considered high-efficiency. Higher SEER units cost more upfront but save money on energy bills over time. For most homeowners, a 16-18 SEER system offers the best balance of cost and efficiency.
How long does an HVAC system last?
A well-maintained central air conditioner lasts 15 to 20 years. Furnaces typically last 15 to 25 years. Heat pumps last 10 to 15 years. Regular maintenance, clean filters, and proper sizing are the biggest factors in equipment longevity.
