If you're uncomfortable working with electrical wiring, or if your HVAC system is complex and requires modifications, it's best to call a professional. Improper installation can damage your HVAC system or create a safety hazard. Also, if the installation requires modifying any warranty-protected components, you must use a qualified technician.

Problem 2: Hidden Costs and Unexpected Add-ons

The initial quote seemed reasonable, but now the contractor is adding on extra charges for things you weren't expecting.

1. Incomplete Initial Assessment: The contractor may not have thoroughly assessed your HVAC system before providing the initial quote. This can lead to unforeseen issues and additional costs.
2. Code Requirements: Local building codes may require specific modifications or upgrades to your HVAC system to accommodate the UV light. These requirements can add to the overall cost.
3. Unexpected Ductwork Issues: Upon closer inspection, the contractor may discover issues with your ductwork, such as leaks or damage, that need to be addressed before installing the UV light.
4. Permitting Fees: Some municipalities require permits for HVAC modifications, which can add to the cost of the installation.

1. Review the Initial Quote Carefully: Before the work begins, review the initial quote with the contractor to ensure it includes all necessary components and services. Ask questions about any unclear or vague items.
2. Ask About Potential Hidden Costs: Specifically ask the contractor if there are any potential hidden costs or unexpected add-ons that you should be aware of. Get their assurance that they will inform you of any additional costs before proceeding with the work.
3. Research Local Building Codes: Do some research on your local building codes to see if there are any specific requirements for UV light installation. This will help you anticipate any potential additional costs.
4. Inspect Ductwork Yourself (Visually): Visually inspect your ductwork for any obvious signs of damage or leaks. While you may not be able to identify all potential issues, this can give you a general idea of the condition of your ductwork.

If you suspect the contractor is being dishonest or is adding on unnecessary charges, consult with another HVAC professional for a second opinion. Get a written quote from the second contractor, and compare it to the original quote. Document all communication with the original contractor in case you need to dispute the charges.

Problem 3: UV Light Not Working After Installation
