FAQs
How do I know when itâs time to replace my HVAC unit instead of repairing it?
If your system is more than 10â15 years old, needs frequent repairs, or your energy bills keep rising despite regular maintenance, replacement is usually more cost-effective. Our certified Maynardville technicians can perform a full inspection, compare repair versus replacement costs, and provide a detailed load calculation to confirm whether a new unit will save you money long-term.
What size HVAC unit do I need for my Maynardville home?
Proper sizing depends on square footage, insulation levels, window type, sun exposure, and even local humidity. We use Manual J load calculations to determine the exact British Thermal Units (BTUs) needed. An undersized unit will run constantly and wear out early, while an oversized unit will short-cycle and waste energy. Our technicians measure your home and provide a written sizing report before recommending equipment.
How long does a typical HVAC replacement take?
Most standard residential replacements in Maynardville are completed in one day. This includes removing the old equipment, installing and testing the new system, updating thermostat controls, and cleaning the work area. Complex jobs that require duct modifications or electrical upgrades may take up to two days; weâll give you a firm timeline before work begins.
What warranties and guarantees come with a new HVAC system?
All systems we install carry a manufacturerâs parts warranty ranging from 10 to 12 years, plus a compressor warranty up to lifetime on select models. We also include a one-year labor warranty and offer extended labor protection plans up to 10 years. In addition, every installation comes with our 100% Satisfaction Guaranteeâif youâre not happy within the first year, weâll make it right at no extra charge.
Will a new HVAC unit lower my energy bills?
Yes. Modern systems are 20â40% more efficient than units made a decade ago. By choosing ENERGY STARÂŽ equipment with a higher SEER2 (cooling) and HSPF2 (heating) rating, youâll reduce monthly utility costs. We can provide a cost-savings analysis that estimates payback time based on your current bills and local Maynardville electricity rates.
Are financing or rebates available for HVAC replacement in Maynardville?
Absolutely. We partner with local utilities and lenders to offer low-interest financing plans with approvals in minutes. TVA EnergyRightÂŽ rebates and manufacturer promotions may also offset part of your purchase price. Our office staff handles all paperwork and will explain every available incentive so you get the maximum savings.
