Get answers to common questions about hvac services in Irmo, South Carolina.
For a full system replacement in Irmo, homeowners can typically expect a range of $5,500 to $12,000+, depending on system size, efficiency, and home layout. Local factors include our humid subtropical climate, which often necessitates systems with strong dehumidification capabilities, and the prevalence of heat pumps due to our relatively mild winters, which can influence equipment choice and cost. Always get multiple itemized estimates from licensed local contractors.
The optimal times are during the mild shoulder seasons of early spring (March-April) and early fall (September-October). Scheduling service during these periods avoids the peak summer demand when HVAC companies are busiest with emergency breakdowns in the 90°F+ heat, ensuring better availability and potentially faster service. This timing also prepares your system for the intense summer cooling season that runs from May through September.
South Carolina requires all HVAC contractors performing work over $200 to be licensed by the SC Department of Labor, Licensing and Regulation (LLR)—always verify this license. While state-specific rebates can change, local utilities like Dominion Energy often offer rebates for upgrading to high-efficiency heat pumps or air conditioners, which are highly effective in our climate. Some local municipalities may also have permit requirements for new installations.
Choose a contractor with strong local references, verifiable SC Master HVAC license, and proof of insurance. A reliable Irmo-based company will perform a detailed load calculation (Manual J) specific to your home, as our high summer humidity makes proper sizing critical. Red flags include refusing to provide a written estimate, pressuring for immediate decisions, or quoting a price solely over the phone without an in-home assessment.
Not necessarily a major failure, but it indicates a significant performance issue. In our high humidity, this is often caused by a dirty evaporator coil, low refrigerant charge, or an aging system struggling to remove both heat and moisture. It can also result from inadequate insulation common in older homes, causing the system to fight excessive heat gain. A local technician can diagnose if it's a repairable issue or a sign your system is undersized or failing.
