FAQs
How can I tell when it’s time to replace my HVAC unit instead of repairing it?
Most systems in Elizabethton last 10–15 years. If your unit is in that age range and you’re facing frequent breakdowns, rising energy bills, uneven temperatures, or your equipment still uses phased-out R-22 refrigerant, replacement is usually the more cost-effective option. Our certified technicians can provide a detailed cost-benefit analysis so you can compare the price of major repairs versus a new, high-efficiency system.
What size HVAC system does my home need?
Proper sizing isn’t about square footage alone; it involves a Manual J load calculation that factors in insulation levels, window efficiency, duct design, ceiling height, and Elizabethton’s climate data. During a free in-home consultation, our technicians will gather these details and recommend the correct tonnage (cooling capacity) and BTU output (heating) to keep you comfortable without over- or under-sizing, which can cause premature wear and high utility costs.
How long does an HVAC replacement take and what happens on installation day?
Most standard change-outs in Elizabethton can be completed in a single day. We start by protecting your floors, safely recovering refrigerant, and removing the old indoor and outdoor units. We then set the new condenser, furnace or air handler, update line sets or electrical as needed, pressure test and vacuum the refrigerant lines, charge the system, and run a full performance check. Before we leave, we’ll show you how to use your new thermostat, register warranties, and haul away all debris for recycling.
Are there energy-efficient units that qualify for rebates or tax credits in Tennessee?
Yes. Many of the ENERGY STAR® heat pumps and air conditioners we install carry SEER2 ratings of 16–20+, qualifying for federal tax credits of up to 30% of the project cost (capped at $2,000 for heat pumps). Tennessee Valley Authority (TVA) EnergyRight incentives and seasonal manufacturer rebates can add $200–$1,000 in savings. Our office handles the paperwork and provides you with the documentation needed for your tax preparer.
What warranties or guarantees come with a new HVAC system installed by your certified technicians?
All equipment is backed by a 10-year manufacturer parts warranty when registered within 60 days, plus our 1-year labor guarantee. Extended labor coverage up to 10 years is available for a small fee. We also include a complimentary one-year maintenance agreement, giving you two precision tune-ups and priority service so your new system operates at peak efficiency.
How much does a complete HVAC replacement cost and do you offer financing?
Pricing depends on system capacity, efficiency rating, ductwork modifications, and accessory options (such as indoor air quality add-ons). In Elizabethton, most full replacements range from $6,000 to $12,000, with high-efficiency variable-speed heat pumps reaching $14,000+. We partner with several lenders to offer 0% APR plans for 12–60 months, low-interest loans, or deferred payments. All estimates are free and include a written proposal with no hidden fees.
