Heating Services in Kingsport, TN

Forced-Air Furnaces

These systems are a popular solution for consistent indoor heat. They use furnaces and ductwork to push warm air throughout your space.

• Many properties operate with a single thermostat, while zoned heating can control temperatures in separate areas.
• Our team installs new systems or upgrades existing ductwork, vents, and controls for consistent airflow and comfort.

Heat Pumps: An Energy-Efficient Option

For those seeking energy-efficient heating, heat pumps offer a cost-effective alternative. They move heat from one location to another instead of generating it, reducing energy consumption.

• Air-source heat pumps extract heat from outdoor air.
• Ground-source (geothermal) heat pumps draw heat from underground, where temperatures remain more stable year-round.

Performance is measured by the Heating Seasonal Performance Factor (HSPF), which indicates how much heat is delivered per unit of energy used.

While geothermal systems can offer higher efficiency, air-source units are more commonly installed in the Tri-Cities due to lower upfront costs and simpler installation. Thompson Electrical Service installs both types for residential and commercial properties.

Custom Ductwork for a Perfect Fit

A major advantage of working with us is our in-house sheet metal fabrication. We can fabricate custom ductwork, vents, and hoods on-site, a perfect fit for your home or business. This hands-on control improves efficiency, airflow, and comfort.

Heating System Repairs & Maintenance

Even well-maintained systems require routine attention to stay efficient and safe. 

Common issues include:

• Uneven heat distribution
• Banging, rattling, or other unusual noises
• Weak airflow or reduced heating
• Rising energy bills without an obvious cause
• Aging equipment, typically 10–15 years or older

Our technicians perform thorough inspections and repairs of all types of heating systems. Services include troubleshooting electrical connections, calibrating thermostats, checking leaks, and replacing faulty components. 

Our Focus on Heating System Safety

Older properties can present unique challenges, such as outdated wiring or complex system layouts. Our licensed technicians know how to navigate these situations safely, keeping your furnace or heat pump operating reliably.

Safety goes beyond the system itself. We can install and maintain smoke detectors, carbon monoxide detectors, and other safety equipment to complement your heating system. Additionally, we provide guidance on energy-efficient upgrades to reduce utility costs while keeping indoor temperatures consistent.

How to Care for Your Heating System

• Replace or clean furnace filters regularly, typically every 1–3 months. This helps maintain proper airflow and supports better indoor air quality.
• Make sure furniture, rugs, or drapes are not blocking vents or registers. Obstructions can restrict airflow and put extra strain on your system.
• Confirm that your thermostat reads temperatures accurately and that seasonal settings match your comfort needs.
• Rattling, grinding, or squealing sounds can be early warning signs of system issues. Contact us promptly to have them checked before they become bigger problems.
