FAQs
Do you really offer same-day HVAC replacement in Maynardville?
Yes. If you call before noon, we can dispatch a licensed technician to assess your existing system, deliver a properly sized replacement unit from our local warehouse, pull the required permits, and complete installation the same dayâweather and equipment availability permitting.
What brands and system types can you install on short notice?
Our warehouse stocks high-efficiency gas furnaces, heat pumps, air conditioners, and packaged units from Trane, Rheem, Goodman, Carrier, and Lennox. Because we keep the most common tonnage and BTU sizes in inventory, we can match nearly any residential requirement without delay.
How is the replacement cost determined?
Pricing is based on system capacity (tonnage or BTUs), efficiency rating (SEER2/HSPF/AFUE), difficulty of installation, and any duct or electrical upgrades needed. After an on-site evaluation, we provide a firm, upfront quote that includes equipment, labor, permits, haul-away of the old unit, and our 10-year parts & labor warrantyâno hidden fees.
Will a same-day install affect quality or long-term reliability?
No. Our NATE-certified crews follow the same Manual J sizing calculations, manufacturer specs, and local code requirements as longer scheduled jobs. The speed comes from stocking equipment locally, using multiple installation teams, and handling permitting electronicallyânot from cutting corners.
Can you replace my HVAC system in winter or after hours?
Absolutely. We perform replacements year-round, including evenings and Saturdays, to restore heat or cooling quickly. Emergency after-hours service carries a modest surcharge to cover overtime labor, but workmanship and warranties are identical to standard-hour installations.
What financing or rebates are available for quick replacements?
We offer 0% APR financing for up to 60 months (with approved credit) plus instant utility rebates for qualifying high-efficiency units. Our comfort advisor will walk you through TVA EnergyRight and federal tax credit options so you can maximize savings while enjoying same-day comfort.
