FAQs

My home addition is making my old HVAC system struggle in the summer. Can you help?

Absolutely. A common issue in Jacksonville is adding square footage without properly sizing the HVAC system. We handle the entire project, from designing and constructing your new room or story addition to assessing and upgrading your heating and cooling capacity. This ensures your entire home stays comfortable, even during our hottest months.

Can you build a new deck or patio that helps with indoor cooling?

Yes. A strategically designed deck, patio, or covered porch can provide shade to your home, reducing direct sun exposure and helping lower indoor temperatures. We construct durable outdoor living spaces with this in mind, and we can also discuss integrating solutions like outdoor ceiling fans or misting systems to enhance comfort around your pool or patio area.

We're building a new home in Jacksonville. How do you ensure the HVAC is right for our climate?

For new single-family, modular, or manufactured home construction, proper HVAC design is critical from the start. We factor in Jacksonville's specific summer heat and humidity, your home's layout, insulation, and window placement to correctly size and install an efficient system. This proactive approach helps prevent common issues like an underperforming air conditioner and ensures long-term comfort and energy savings.
