Frequently Asked Questions
What are HVAC retrofitting services?
Retrofitting involves upgrading parts of an existing heating or cooling system to improve efficiency, comfort, and performance without replacing the entire unit. Climate Guys provide professional retrofitting for older homes and HVAC systems throughout Holland, MI and nearby communities.
Why is retrofitting beneficial for older homes in West Michigan?
Many homes in Holland and surrounding areas were built before energy-efficient HVAC technology became standard. Retrofitting helps:
- Reduce energy consumption
- Improve indoor comfort
- Solve airflow or zoning issues
- Extend system lifespan
- Lower monthly utility bills
It’s an affordable alternative to full system replacement.

Each upgrade is customized to fit your system’s needs and home’s layout.
How do I know if my home needs retrofitting?
You may benefit from retrofitting if you notice:
- Uneven temperatures across rooms

Climate Guys can perform a full system evaluation to determine the best retrofit options.
