AC Installation & Replacement in Kingsport

Installing or replacing a central air conditioning system is often more straightforward than property owners expect, particularly in homes that already have furnace ductwork in place. We can retrofit existing ducts to work with a new AC unit. It’s a cost-effective upgrade that can deliver consistent cooling throughout the property.

All sheet metal fabrication, ductwork, and vents are completed on-site by our own team. Fabricating to exact measurements on location minimizes errors, keeps costs down, and can shorten the overall project timeline compared to ordering prefabricated components.

How We Select the Right AC System for Your Property

Choosing the right unit means matching the system to your property’s specific demands, not just picking a size from a chart. Before recommending any equipment, our team works through several evaluation factors:

• Unit size. Systems that are too small run continuously, increasing energy use and wear. Units that are too large cycle inefficiently, consuming excess electricity.
• Heat-gain calculations. We assess square footage, insulation, window placement, sunlight exposure, and overall layout to determine the correct cooling capacity for the space.
• SEER efficiency rating. SEER (Seasonal Energy Efficiency Ratio) measures a system’s cooling output relative to the total electrical energy it consumes over a typical cooling season. Federal minimum standards apply to new residential equipment, and higher-rated systems can reduce long-term energy costs.
• Compatibility. We verify that new AC systems integrate with existing thermostats, ductwork, and zoning controls before installation begins.

AC Repair for Kingsport Homes & Businesses

When an air conditioning system stops cooling, runs constantly, or behaves erratically, the cause isn’t always the HVAC equipment itself. Refrigerant leaks, faulty capacitors, compressor issues, thermostat malfunctions, and restricted airflow from dirty coils or blocked ductwork are all common culprits. So are electrical faults tied to the system.

Because Thompson Electrical Service holds both electrical and HVAC licenses, our technicians can diagnose the full picture and repair both the cooling system and any related electrical issue on the same service call. We serve residential and commercial customers throughout Kingsport and the Tri-Cities, with 24/7 availability when a breakdown can’t wait.
