Why Licensing Matters for Air Conditioner Installation
Installing an air conditioning system involves complex electrical and mechanical work. A licensed HVAC technician ensures that your system is installed according to code, which helps protect your home, ensures energy efficiency, and maintains your warranty coverage. Licensing also means that the installer has undergone proper training, passed exams, and adheres to safety regulations.
In Missouri, state regulations do not require a license for HVAC contractors, but many cities and counties, including those in the greater St. Louis area, have their own rules. For example, St. Louis County and the City of St. Louis require HVAC professionals to hold specific mechanical licenses. That means if you or an unlicensed contractor installs your system improperly, you could face code violations, safety hazards, and even legal consequences.
The Risks of Unlicensed Installation
Trying to save money by installing your air conditioner without a license may cost more in the long run. Here are a few potential problems homeowners may face:
- Improper sizing or configuration: Without proper knowledge, it’s easy to install a system that is too large or too small, leading to inefficiency, uneven cooling, or premature system failure.
- Refrigerant handling violations: Only certified professionals can legally handle refrigerants like R-410A due to EPA regulations.
- Electrical issues: AC systems require electrical wiring that must comply with safety codes. A mistake could cause a fire or power outage.
- Voided warranties: Most manufacturers will not honor a warranty if the installation was not performed by a licensed professional. Learn more about ways to accidentally void your AC warranty.
