FAQs
How can I tell if my HVAC system in Hixson needs a full replacement rather than another repair?
Several signs point to replacement: (1) Age—systems over 12-15 years old are nearing the end of their life cycle; (2) Rising utility bills—older equipment loses efficiency and costs more to run; (3) Frequent breakdowns—if you are calling for repairs more than once a year, the cumulative cost generally exceeds the value of a new unit; (4) Uneven temperatures or humidity problems throughout the home; and (5) R-22 refrigerant usage—units still using the phased-out refrigerant are expensive to recharge and cannot meet today’s efficiency standards. A professional load calculation and diagnostic from a certified Hixson technician will confirm whether replacement is the more economical choice.
What modern technologies are available in today’s replacement HVAC units?
Current systems feature variable-speed compressors and blower motors that operate at multiple stages for precise temperature control, inverter-driven heat pumps that maintain comfort even in low temperatures, smart thermostats with Wi-Fi and learning algorithms, zoning capabilities that allow different areas of your home to be conditioned separately, and indoor air quality add-ons such as UV lights and high-MERV filtration. Many new furnaces also use modulating gas valves that adjust output in 1% increments, improving efficiency and comfort.
How long will a typical HVAC replacement take in the Hixson area?
Most residential change-outs can be completed in one full day, including removal of the old equipment, installation of the new indoor and outdoor units, reconnecting electrical and refrigerant lines, and startup testing. If ductwork modifications, zoning, or additional IAQ accessories are added, the job may extend to two days. Your contractor should provide a written timeline after a pre-installation inspection.
What energy savings can I expect from upgrading to a high-efficiency unit?
New air conditioners and heat pumps now reach SEER2 ratings of 15–20+, and gas furnaces achieve AFUE ratings up to 98%. Upgrading from a 10 SEER system to an 18 SEER model can cut cooling costs by about 40%. Over the 15-20-year lifespan of the equipment, that typically translates to thousands of dollars in lower utility bills. In Hixson’s mixed climate, heat pumps with variable-speed technology often provide the greatest year-round savings.
Are rebates, tax credits, or financing options available for HVAC replacements in Hixson?
Yes. TVA’s EnergyRight program frequently offers incentives for qualifying high-efficiency heat pumps installed by approved contractors. Federal tax credits under the Inflation Reduction Act provide up to $2,000 for heat pumps meeting specified efficiency tiers and $600 for qualifying furnaces or air conditioners. Many local utilities, such as EPB, also run seasonal rebate programs. Reputable HVAC companies in Hixson typically offer 0% APR financing for 12–60 months through third-party lenders, making the upgrade more affordable.
How do I ensure I choose the right-sized system and a reputable installer?
Correct sizing is determined by a Manual J load calculation that takes into account square footage, insulation, window orientation, air infiltration, and occupant habits—rules of thumb based only on tonnage per square foot should be avoided. Look for NATE-certified technicians, a contractor licensed in Tennessee with proof of insurance, and strong reviews from Hixson homeowners. Request at least two written proposals that specify equipment model numbers, efficiency ratings, labor warranties, and total installed price. A quality installer will also offer a post-installation walkthrough and 1-year workmanship guarantee.
