FAQs
What qualifies as a “high-efficiency” HVAC system, and why is it worth it for Maryville homes?
A high-efficiency HVAC unit is engineered to deliver more heating or cooling with less energy. Air conditioners and heat pumps are rated by Seasonal Energy Efficiency Ratio 2 (SEER2); anything 15.2 SEER2 or higher is considered high-efficiency in Tennessee’s climate zone. Furnaces are rated by Annual Fuel Utilization Efficiency (AFUE); 95 % AFUE or above meets the high-efficiency threshold. Because Maryville’s summers are humid and winters can dip below freezing, a high-efficiency system can cut annual utility bills by 25-40 %, improve indoor comfort with better humidity control, and reduce wear on components, extending equipment life.
How can I tell it’s time to replace—rather than repair—my current HVAC unit?
Industry guidelines say replacement makes financial sense when your system is 10-15 years old, needs frequent or costly repairs, or struggles to maintain set temperatures. In Maryville’s climate, compressors and heat exchangers that fail early can push repair costs above 30 % of the price of a new unit, tipping the balance toward replacement. Rising energy bills, excessive noise, or hot-and-cold spots in your home are additional red flags that the system’s efficiency has dropped and an upgrade will save money long-term.
What does a typical high-efficiency HVAC replacement cost in Maryville, and are incentives available?
Prices vary by size, brand, and installation complexity, but most Maryville homeowners spend $7,500-$12,000 for a high-efficiency gas furnace and air conditioner combo, or $9,000-$15,000 for a dual-fuel or all-electric heat-pump system. Financial help is available: • Federal tax credits under the Inflation Reduction Act provide up to $2,000 for qualifying heat pumps and 30 % (up to $600) for high-efficiency air conditioners or furnaces. • TVA’s EnergyRight program offers rebates up to $1,000 on select heat pumps. • Sevier County Electric and other local utilities have low-interest on-bill financing. Our comfort consultants handle all paperwork to make sure you get every dollar you qualify for.
How long will the HVAC replacement take, and will I be without heating or cooling during the process?
Most standard change-outs are completed in a single day—typically 6-8 hours—including removal of the old equipment, installation of the new indoor and outdoor units, refrigerant charging, and start-up testing. If new ductwork, electrical upgrades, or a line-set relocation is required, the job may extend to two days. We coordinate installation so you’re without heating or cooling for only a few hours; portable heaters or spot coolers can be provided during extreme weather to keep your family comfortable.
Should I replace my furnace and air conditioner together or can I do them separately?
You can replace them separately, but there are advantages to a matched system. Today’s high-efficiency equipment uses variable-speed blowers and advanced refrigerants that operate best with a compatible indoor coil or furnace. A mismatched system can lose 10-15 % efficiency and void manufacturer warranties. If one unit is more than 10 years old or uses R-22 refrigerant, replacing both at once usually delivers better comfort, lower energy bills, and a full 10-year parts warranty—all while saving on labor since both units are installed during a single visit.
What maintenance and warranties come with a new high-efficiency HVAC system?
Manufacturers provide 10-year parts and compressor warranties on most high-efficiency models when they’re registered within 60 days; many add a lifetime heat-exchanger warranty on 95 %+ AFUE furnaces. We include a one-year labor warranty and offer optional Comfort Club plans that cover bi-annual tune-ups, priority service, and discounts on filters and repairs. Routine maintenance—spring AC tune-up and fall furnace or heat-pump inspection—keeps your warranty valid, maximizes energy savings, and can add 3-5 years to the unit’s life expectancy.
