FAQs
How do I know when it’s time to replace my HVAC unit in Cosby rather than repair it again?
Most systems in our humid East Tennessee climate last 10–15 years. Consider replacement if your unit is over a decade old and: (1) needs frequent or costly repairs, (2) struggles to keep set temperatures or dehumidify, (3) shows a dramatic rise in energy bills, or (4) still uses R-22 refrigerant, which is no longer produced. A professional load calculation and inspection can confirm whether upgrading will save you more than another major repair.
What size HVAC system do I need for my Cosby home?
Proper sizing is critical. Our consultants perform an ACCA Manual J load calculation that factors in square footage, insulation, window type, air leakage, and local design temperatures for Cosby (about 17 °F winter/89 °F summer). Oversized units short-cycle and waste energy; undersized units run constantly and wear out. After the Manual J, we match the result to an appropriately sized heat pump or split system using Manual S equipment selection guidelines.
How much does a complete HVAC replacement typically cost in the Cosby area?
Prices vary by capacity, efficiency rating, and whether you choose a furnace/AC combo or all-electric heat pump. In 2024, most homeowners spend $6,500–$12,000 for a standard 14–16 SEER2 system, while high-efficiency variable-speed units (18–20 SEER2) run $11,000–$18,000. Duct modifications, smart thermostats, and indoor-air-quality add-ons increase costs. We provide a written, line-item estimate and review financing, utility rebates, and federal tax credits that can offset 30 % of qualifying high-efficiency installations.
How long will the replacement take and will I be without heating or cooling?
A straightforward change-out usually takes one full working day. If we must replace or seal ductwork, add a new line set, or upgrade the electrical service, plan on 1½–2 days. We remove the old equipment, set the new outdoor unit on a leveled pad, install or adapt the indoor coil/air handler, pressure-test and evacuate the refrigerant lines, pull permits, and start up the system. You may be without conditioned air for several hours, but we schedule around extreme weather whenever possible.
Do I need any permits or inspections for an HVAC replacement in Cosby?
Yes. Cocke County and the City of Cosby require mechanical permits for equipment replacements involving refrigerant or electrical work. Our licensed team obtains the permit, schedules any mid-job and final inspections, and provides you with a copy for your records. Passing inspection ensures the installation meets current building, fire, and energy codes.
What warranties and maintenance recommendations come with a new HVAC system?
Most manufacturers offer 10-year parts warranties when the unit is registered within 60 days; compressors often carry lifetime limited coverage on premium models. We add a 1-year labor warranty and offer affordable extended-labor plans up to 10 years. To keep warranties valid, you must schedule professional maintenance twice a year—one cooling tune-up in spring and one heating tune-up in fall. Regular filter changes (every 30–90 days), cleared condensate drains, and thermostat battery checks help maximize efficiency and lifespan.
