FAQs
When should I consider replacing my HVAC unit in Lenoir City?
Most systems last 12â15 years. If your energy bills keep rising, repairs are becoming frequent or expensive, or rooms are no longer heating or cooling evenly, itâs usually more cost-effective to replace the unit. Our licensed technicians can perform a load calculation and cost-benefit analysis so you know whether repair or replacement is the smarter investment for Lenoir Cityâs climate.
How long does a typical HVAC replacement take?
A standard change-out (same size and location) usually requires one full working dayâabout 6â8 hours. If new ductwork, electrical upgrades, or an added zoning system is needed, the job may extend to two days. We schedule around your availability and keep disruptions to a minimum, leaving your home clean at dayâs end.
Are your technicians fully licensed and insured in Tennessee?
Yes. Every installer holds a current State of Tennessee HVAC Contractorâs License, EPA Section 608 refrigerant certification, and carries full liability and workersâ compensation insurance. We also undergo annual factory training, ensuring your new system is installed to code and in compliance with manufacturer specificationsârequirements for preserving the warranty.
How do I know what size HVAC system my house needs?
Proper sizing isnât about square footage alone. Our team performs a Manual J load calculation that considers insulation levels, window orientation, air leakage, occupancy, and even the direction your home faces in Lenoir Cityâs summer sun. The result is a right-sized unit that avoids short cycling, lowers energy costs, and improves humidity control.
Are there energy-efficiency rebates or financing options available?
Absolutely. High-efficiency heat pumps and air conditioners that meet ENERGY STARÂŽ and TVA standards often qualify for utility rebates and potential federal tax credits. We handle the paperwork and can bundle rebates into your quote. For out-of-pocket costs, we offer 0% APR promotional financing (with approved credit) and flexible payment plans through trusted lenders.
What warranties and post-installation support do you provide?
Most systems come with a 10-year parts warranty from the manufacturer when registered within 60 days. Our company adds a 1-year labor warranty at no additional cost and offers optional extended labor coverage up to 10 years. To keep your new HVAC running efficiently, we recommendâand can enroll you inâour Precision Tune-Up Plan, which includes bi-annual maintenance, priority service, and discounts on any future repairs.
