FAQs
When should I consider replacing my HVAC unit instead of repairing it?
You should start thinking about replacement if your system is more than 10–15 years old, requires frequent or costly repairs, experiences uneven temperatures, or causes utility bills to spike. In Charleston’s hot, humid climate, older units also tend to struggle with de-humidification, which can lead to indoor air-quality issues. A professional inspection and cost-benefit analysis can confirm whether investing in a new, higher-efficiency system will save you money and improve comfort in the long run.
How long does an HVAC replacement normally take for a Charleston home?
Most standard change-outs are completed in a single day: roughly 4–8 hours for removal, installation, and start-up. Complex projects—such as upgrading ductwork, adding zoning controls, or relocating equipment—can extend the timeline to two days. We always perform a pre-installation survey so you know exactly how long your specific project will take and how we’ll minimize disruption to your household.
What size HVAC system is right for my house?
Choosing the correct size is critical. Oversized units short-cycle, waste energy, and fail to remove humidity; undersized units run constantly and still can’t keep you comfortable. We perform a Manual J load calculation that factors in square footage, insulation levels, window orientation, air leakage, and Charleston’s design temperatures. This data lets us recommend the precise tonnage and airflow your home needs for optimal efficiency and comfort.
Are there high-efficiency models that handle Charleston’s humidity?
Yes. Modern heat pumps and air conditioners with variable-speed compressors, multi-stage cooling, and high SEER2/IEER ratings excel in humid climates. Models with built-in de-humidification logic or paired whole-home dehumidifiers keep indoor relative humidity around 50%, reducing mold and allergens. We’ll walk you through Energy Star and ENERGY STAR Most Efficient options that qualify for utility rebates while meeting the unique moisture-control demands of the Lowcountry.
Do you take care of permits and disposal of the old equipment?
Absolutely. Charleston County requires mechanical permits for most HVAC replacements, and we handle the paperwork, inspections, and fees on your behalf. Your old equipment is removed, evacuated of refrigerant per EPA Section 608 guidelines, and recycled or disposed of at approved facilities. All scrap metal, cardboard, and refrigerant are processed responsibly, leaving you with nothing to worry about.
What financing, rebates, or tax incentives are available for HVAC replacements?
Local utilities such as Dominion Energy South Carolina offer rebates—often $300–$700—when you install ENERGY STAR-qualified heat pumps or air conditioners. Federal tax credits (25C) can cover up to 30% of the project cost, capped at $600 for air conditioners and $2,000 for qualifying heat pumps through 2032. We partner with lenders that provide 0% APR short-term plans and low-interest options up to 120 months. During your consultation we’ll outline every available incentive and even complete the paperwork so you receive the maximum savings.
