FAQs

What qualifies as a high-efficiency air conditioner?

In Tennessee, the U.S. Department of Energy now rates new central air conditioners with the SEER2 scale (Seasonal Energy Efficiency Ratio 2). Anything at or above 15.2 SEER2 (roughly equivalent to 16 SEER on the former scale) is considered high-efficiency. ENERGY STAR-certified systems meet or exceed this threshold and also include features such as variable-speed fans, two-stage or inverter-driven compressors, and upgraded coil designs that reduce energy use while maintaining comfort.

How much can I save on my energy bills by upgrading to a high-efficiency system in Greeneville?

Utility data for East Tennessee shows that moving from a 10–12 SEER system installed 10–15 years ago to a 16–18 SEER2 unit can cut cooling costs 30-45 %. For a 2,000 sq ft home with an average summer electric bill of $180, that’s a savings of $50–$80 per month during peak season and $300-$450 per cooling season. Over a 15-year lifespan the upgrade typically pays for itself and then some, especially as local power rates continue to rise.

Are there rebates or tax incentives available locally for installing high-efficiency AC units?

Yes. Through the TVA EnergyRight program, homeowners in Greeneville Light & Power’s service area can earn rebates of $300–$550 when they install an eligible high-efficiency heat pump or central AC. In addition, the federal Inflation Reduction Act offers a 30 % tax credit (up to $600 for an AC or $2,000 for a heat pump) for equipment that meets the Consortium for Energy Efficiency’s Tier 2 standards. Manufacturers often add seasonal instant rebates, and our team handles all paperwork so you receive every available dollar.

Will a high-efficiency system improve indoor comfort and humidity control in Greeneville's climate?

Absolutely. High-efficiency equipment uses variable-speed indoor blowers and multi-stage compressors that can run at low capacity for long periods. This extended runtime allows the system to pull more moisture out of the air, keeping relative humidity in the 45-55 % range even on muggy summer days. The result is fewer temperature swings, quieter operation, and a cooler-feeling home at slightly higher thermostat settings—another way you save energy without sacrificing comfort.

How do variable-speed and two-stage compressors contribute to efficiency?

Traditional single-stage compressors are either 100 % on or completely off, causing frequent starts that draw large amounts of electricity. Two-stage units add a lower-capacity stage (around 65 %) for mild weather, while inverter-driven variable-speed compressors can modulate in tiny increments from roughly 25 % to 100 % output. By matching capacity to the exact load, they reduce start-up spikes, maintain steadier temperatures, and use up to 30 % less energy than single-stage models.

What maintenance is required to keep a high-efficiency air conditioner performing at its best?

High-efficiency systems rely on precise airflow and refrigerant levels. We recommend (1) replacing or cleaning filters every 1–3 months, (2) scheduling professional tune-ups each spring to check refrigerant charge, electrical components, and coil cleanliness, (3) keeping the outdoor condenser free of debris and shrubbery at least 2 ft on all sides, and (4) ensuring supply and return vents remain unobstructed. Regular maintenance can preserve up to 95 % of the unit’s original efficiency, prevent costly breakdowns, and keep manufacturer warranties valid.
