FAQs
What makes an air conditioner “high-efficiency” and how is it measured?
A high-efficiency air conditioner is one that delivers the same or greater cooling output while using significantly less electricity than a standard model. Efficiency is measured by the Seasonal Energy Efficiency Ratio 2 (SEER2), which indicates how many BTUs of cooling the unit provides per watt-hour consumed over an entire cooling season. The federal minimum for new systems in Tennessee is currently 14.3 SEER2, but high-efficiency models typically rate 16–25 SEER2. Features such as variable-speed compressors, electronically commutated motors (ECMs), and advanced coil designs further improve performance and reduce energy use.
How much could I save on my energy bills by replacing my old AC with a high-efficiency system in Cowan?
Savings depend on the efficiency gap between your existing unit and the new one, as well as how often you run your AC during Cowan’s hot, humid summers. If you upgrade from a 10-SEER system installed in the early 2000s to a 17-SEER2 model, you can expect electricity consumption for cooling to drop by roughly 35–45 %. For a typical Cowan home that spends about $1,000 a year on summer cooling, that equates to $350–$450 in annual savings, quickly offsetting the higher upfront cost.
Is my current ductwork and electrical service compatible with a high-efficiency replacement?
In most Cowan homes, existing ductwork and electrical service can be used, but an evaluation is essential. High-efficiency systems often use variable-speed indoor blowers that require proper duct sizing and minimal leakage to achieve their rated SEER2. Our technicians perform a pressure test and visual inspection to identify gaps, kinks, or undersized runs. Minor sealing or additional returns may be recommended. Electrically, today’s high-efficiency condensers usually operate at lower amperage than older units, but the breaker size and wire gauge still need verification. We include these checks in every replacement quote and handle any needed upgrades.
Are there rebates or tax incentives available in Cowan for high-efficiency air conditioner replacements?
Yes. Tennessee Valley Authority (TVA) occasionally offers rebates—often $150–$300—when you install a qualifying ENERGY STAR® heat pump or central AC through a participating contractor. Federal tax credits under the Inflation Reduction Act cover 30 % of the project cost, up to $600 for qualifying central air conditioners and up to $2,000 for heat pumps meeting specific efficiency thresholds. Low- to moderate-income households may also be eligible for forthcoming High-Efficiency Electric Home Rebates (HEEHR). We stay current on all programs, prepare the paperwork, and apply the rebate as an instant discount whenever possible.
How long will the installation take, and will I be without cooling during the process?
A straightforward replacement—condenser, coil, and thermostat—typically takes one full day. If ductwork modifications, electrical upgrades, or a new air handler are required, the job may extend into a second day. You will be without cooling only while the existing equipment is disconnected, usually 4–6 hours. We schedule installations early in the morning, provide temporary fans if needed, and restore cooling the same evening in almost every case.
What maintenance is required to keep a high-efficiency system operating at peak performance?
High-efficiency units rely on precise airflow and refrigerant charge, so regular maintenance is critical. Homeowners should replace or clean filters monthly during peak season and keep the outdoor condenser free of grass clippings and debris. Professionally, we recommend a semi-annual tune-up: once in spring for cooling, once in fall for heating if it’s a heat pump. Our technicians check refrigerant levels, clean coils, test capacitors, calibrate thermostats, and verify static pressure. Preventive maintenance helps preserve the manufacturer’s warranty, maintains SEER2 performance, and can extend equipment life beyond 15 years.
