Starting an HVAC business in Texas can be highly profitable thanks to the state’s hot climate, rapid population growth, and year-round demand. From Houston and Dallas to Austin, San Antonio, Fort Worth, and El Paso, homeowners and businesses rely heavily on HVAC contractors to stay comfortable.
This guide walks you through how to legally start, insure, market, and scale a successful HVAC business in Texas.
Step 1: Understand Texas HVAC Licensing Requirements
To operate legally, HVAC contractors in Texas must be licensed through the Texas Department of Licensing and Regulation (TDLR). You’ll need:
A Class A or Class B HVAC license
Verified work experience
Passing scores on required exams
Proof of insurance and financial responsibility
Operating without proper licensing can result in fines and lost contracts, especially in large markets like Houston and Dallas.
Step 2: Register and Structure Your HVAC Business
Choose a business structure such as an LLC or corporation to protect personal assets. Register your business with the Texas Secretary of State and obtain an EIN from the IRS.
This step is critical if you plan to serve commercial clients in cities like Austin or San Antonio, where larger contracts often require formal business documentation.
Step 3: Get the 5 Necessary Insurances for HVAC Businesses in Texas
Insurance is essential for protecting your HVAC business from financial loss and meeting licensing or contract requirements.
Covers property damage and bodily injury caused during HVAC work.
Protects employees injured on the job. While not required statewide in Texas, many clients require it.
Covers service trucks and vans used to travel across Fort Worth, El Paso, and surrounding areas.
Protects against claims related to faulty HVAC installation or system design.
Covers expensive HVAC tools, diagnostic equipment, and materials against theft or damage.
