FAQs
What are the most common signs that my HVAC unit should be replaced instead of repaired?
Frequent breakdowns, uneven temperatures, rising utility bills, loud or unusual noises, and equipment that is 12–15+ years old are strong indicators that replacement is more cost-effective than another repair. Modern systems are far more efficient, so upgrading often pays for itself through lower energy and repair costs.
How much does a full HVAC replacement cost in Cosby, and what affects the final price?
In Cosby, complete heating and air-conditioning replacement typically ranges from $6,500 to $13,000. Price varies with system size (measured in tons or BTUs), efficiency rating (SEER2, AFUE, HSPF2), ductwork modifications, add-ons like smart thermostats or air purifiers, brand, and labor complexity (attic vs. crawl-space installs, electrical upgrades, etc.). We provide free in-home evaluations so you receive an exact quote before any work begins.
How do I determine the right size HVAC unit for my home?
Proper sizing is critical. We perform a Manual J load calculation that measures square footage, insulation levels, window types, sun exposure, and the number of occupants. This science-based approach ensures your new system isn’t undersized (leading to constant running) or oversized (causing short cycling, humidity issues, and wasted energy).
How long will it take to replace my HVAC system and what should I expect on installation day?
Most standard replacements in Cosby are completed in one day. Our crew arrives promptly, protects flooring with drop cloths, removes the old equipment, installs the new air handler, condenser, lineset, and thermostat, then pressure-tests and charges the refrigerant circuit. A final start-up procedure verifies airflow, refrigerant levels, and system safety. We finish with a customer walk-through, system tutorial, and full job-site cleanup.
Will a new HVAC system really lower my energy bills, and which efficiency ratings matter most?
Yes. Replacing a 10-SEER air conditioner from 2006 with today’s 16–18 SEER2 model can cut cooling costs by 30–45%. On the heating side, upgrading an 80% AFUE furnace to 96%+ saves up to 20% on winter fuel. High-efficiency heat pumps (with HSPF2 8.1+ ratings) offer similar reductions. Pairing the new unit with a variable-speed blower, smart thermostat, and sealed ducts maximizes monthly savings.
Are permits or inspections required for HVAC replacement in Cosby, and do you handle them?
Yes. Sevier County and the City of Cosby require mechanical permits and a post-installation inspection to ensure code compliance. Our team pulls all necessary permits, schedules the inspector, and provides documentation for your records. You won’t have to navigate any paperwork—we handle the entire process from start to finish.
