Common HVAC Technicians services in Charleston
AC Installation & Replacement
Sizing a new system requires load calculations — an oversized unit short-cycles and leaves air humid. HVAC technicians size, install, and commission new equipment correctly.
Furnace Repair & Installation
From ignitor replacements to full heat exchanger failures, HVAC techs diagnose and repair gas and electric furnaces, or recommend replacement when repair costs exceed value.
Duct Cleaning & Sealing
Leaky ducts waste 20–30% of conditioned air. Technicians use blower door tests and mastic sealant to tighten duct systems and improve efficiency.
Annual Tune-Up & Maintenance
Spring AC and fall furnace tune-ups catch failing components before they cause a system-down emergency in peak season. Most techs offer annual maintenance contracts.
Mini-Split Installation
Ductless mini-splits are ideal for room additions, garages, and older homes. Installation requires refrigerant line routing and electrical — a licensed HVAC contractor is required.

How to hire a hvac technician in Charleston
Verify EPA 608 certification
Any technician handling refrigerant must hold an EPA 608 certificate. This is federal law — ask to see it before any refrigerant work is performed.
Request a Manual J load calculation
For new system installs or replacements, a proper Manual J heat load calculation ensures the unit is correctly sized. Skip this and you'll likely end up with an oversized, inefficient system.
Compare SEER ratings
Higher SEER (Seasonal Energy Efficiency Ratio) means lower operating costs. Ask your technician to show you the payback period on higher-efficiency equipment vs. base models.
Understand warranty terms
HVAC warranties typically require annual professional maintenance to stay valid. Get clarity on what voiding conditions apply before you sign the installation agreement.
Ask about emergency availability
The best HVAC companies offer 24/7 emergency service. Confirm what the after-hours rate is so there are no surprises when the AC fails on a Friday night in August.

HVAC Technicians operating in Charleston, SC must comply with local building codes enforced by the Charleston Building and Safety Department.
