FAQs

What does it mean that your technicians are NATE-certified, and why is that important for my HVAC replacement?

NATE (North American Technician Excellence) certification is the industry’s most widely recognized credential for HVAC professionals. To earn it, technicians must pass rigorous testing on installation, service, and safety. When a NATE-certified technician replaces your HVAC unit, you benefit from proven expertise, fewer callbacks, correct sizing and charging, and workmanship that meets or exceeds manufacturer specifications—helping your new system run efficiently, last longer, and stay under warranty.

How do I know when it’s time to replace my HVAC unit instead of repairing it?

A replacement is usually recommended when your unit is 10–15 years old, requires frequent or costly repairs (exceeding about 30% of the price of a new system), uses R-22 refrigerant, or struggles to keep your Charleston home comfortable despite rising energy bills. Our NATE-certified technicians perform a full load calculation, energy-use audit, and system inspection to give you clear data on whether repair or replacement is the smarter long-term choice.

What HVAC systems are best suited for Charleston’s humid subtropical climate?

Charleston’s hot, muggy summers and mild winters favor high-SEER2 heat pumps, variable-speed air conditioners paired with gas furnaces (dual-fuel systems), and advanced dehumidification controls. We recommend equipment with coastal corrosion-resistant coils and cabinets, smart thermostats, and enhanced filtration for pollen and salt air. During your free estimate, we’ll discuss each option’s humidity control, efficiency ratings, and compatibility with your home’s ductwork.

How long does a typical HVAC replacement take, and will I be without heating or cooling during the process?

Most standard residential replacements are completed in one day. Our crew arrives with all equipment, removes and recycles the old unit, installs the new system, tests refrigerant charge and airflow, and cleans the workspace. You’ll experience only a brief outage—usually 4–6 hours. Larger homes, duct modifications, or IAQ add-ons (e.g., whole-house dehumidifiers) can extend the job to two days, but we’ll schedule around weather conditions to keep you as comfortable as possible.

What factors affect the cost of an HVAC replacement in Charleston?

Key cost drivers include system size (tonnage/BTUs), efficiency rating (SEER2/HSPF), type (heat pump, AC + furnace, ductless), coastal-grade corrosion protection, thermostat and IAQ upgrades, electrical or ductwork changes, and permit fees required by Charleston County or city municipalities. Our written proposals break down equipment, labor, and permit costs so you can compare options line-by-line before approving any work.

Are there rebates, tax credits, or financing options available to help with my new HVAC system?

Yes. Energy-efficient heat pumps and air conditioners qualifying for ENERGY STAR® may earn up to $2,000 in federal tax credits under the Inflation Reduction Act. SCE&G and Berkeley Electric Cooperative periodically offer utility rebates on high-efficiency equipment. We partner with lenders to provide 0% or low-APR financing, same-as-cash plans, and easy online applications so you can spread payments over 6–120 months. Our office will identify every incentive you qualify for and handle the paperwork for you.
