Common Mistakes to Avoid

1
Working without EPA 608 certification — it is federally illegal to purchase refrigerants without certification
2
Not building a service agreement portfolio — maintenance agreements provide $150-$300/system in annual recurring revenue
3
Undercharging for after-hours emergency calls — summer AC failures are emergency situations justifying $150-$250/hour
4
Not diversifying into commercial HVAC — commercial jobs are larger, less seasonal, and often more profitable
5
Skipping proper refrigerant recovery — illegal venting of refrigerants results in EPA fines up to $44,539/day

Next Steps to Launch Your HVAC Business

1
Form your LLC in Maine — HVAC contractors face significant liability for refrigerant handling and equipment installations (filing fee: $175)
2
Obtain EPA Section 608 Universal certification — required by federal law to purchase and handle refrigerants (R-22, R-410A, R-32); take the exam through ESCO Group
3
Obtain your Maine HVAC contractor license — most states require a specialty contractor license with exam, experience, and financial documentation
4
Get a contractor surety bond ($10,000–$25,000) and HVAC contractor liability insurance ($1,500–$5,000/year)
5
Complete OSHA 10-hour construction safety training — required by commercial property managers and most new construction GCs
6
Open trade accounts with Ferguson HVAC, Johnstone Supply, or Maine regional HVAC distributors for equipment and parts
7
Register for NATE (North American Technician Excellence) certification — differentiates your technicians and is required by some manufacturer warranties
8
Set up service agreement software (ServiceTitan or Housecall Pro) to offer maintenance plan memberships generating recurring annual revenue

Frequently Asked Questions

Starting an HVAC business costs $20,000 to $200,000. A solo HVAC technician with a used van and basic equipment can launch for $20,000-$40,000. A 2-3 technician company with equipped vans, a parts inventory, and a service agreement program typically costs $70,000-$150,000. Larger commercial HVAC contractors can exceed $200,000.

Required: EPA Section 608 certification (universal level covers all refrigerants, $20-$50 exam fee). Recommended: North American Technician Excellence (NATE) certification for credibility. State contractor licenses vary — most states require a licensed HVAC contractor to pull permits and employ technicians.

HVAC service call rates: $75-$150 minimum service call fee, $75-$150/hour for repair labor. Equipment installation: furnace $800-$2,500, AC unit $3,000-$7,000, heat pump $4,000-$10,000 (equipment + labor). Maintenance agreements: $150-$300/system/year. Emergency after-hours calls: 1.5-2x standard rates.

HVAC is highly seasonal — AC work peaks May-September and heating work peaks November-February in most of the US. The shoulder seasons (spring tune-ups, fall start-up) are driven by maintenance agreements. Companies with strong maintenance agreement portfolios have more consistent year-round revenue. Sun Belt markets (Arizona, Florida, Texas) have year-round AC demand.

Top channels: (1) Google search ads for 'AC repair near me' and 'furnace repair' are the highest-converting source, (2) annual maintenance agreement campaigns, (3) Angi and HomeAdvisor for residential, (4) property management companies for multi-unit commercial work, and (5) referrals from satisfied customers (the best long-term source).
