FAQs
How do I know it’s time to replace my HVAC unit instead of repairing it?
Most systems should be considered for replacement when they are 10–15 years old, require frequent or costly repairs, run on discontinued R-22 refrigerant, cause noticeably higher utility bills, or can no longer keep every room in your Duff home comfortable. Our certified technicians perform a full diagnostic and cost-benefit analysis so you can see whether continued repairs or a new unit makes better financial sense.
What is the typical HVAC replacement process with your certified technicians in Duff?
1) We start with a free in-home consultation and Manual J load calculation to determine the exact capacity your home needs. 2) You receive written equipment options, efficiency ratings, and pricing. 3) Once you choose a system, we pull the required Duff permits and schedule installation. 4) On installation day we protect floors, recover refrigerant, remove the old equipment, modify or replace the pad, ductwork, line set, or electrical as needed, install the new unit, pressure-test and evacuate the refrigerant circuit, and commission the system. 5) After a final quality inspection and thermostat tutorial, we haul away debris and register your warranty for you.
How long does a full heating and air-conditioning replacement usually take?
Most straight change-outs are completed in a single workday (6–8 hours). Projects that involve major duct revisions, electrical upgrades, or adding IAQ accessories can take 1–3 days. We schedule inspections with the City of Duff as soon as the work is finished so you experience as little downtime as possible.
What does a new HVAC system cost in Duff, and what drives the price?
For an average 1,800–2,400 sq ft home, replacement costs typically fall between $5,500 and $11,000, installed. Price is affected by capacity (tonnage or BTUs), energy efficiency (SEER2, HSPF, AFUE ratings), whether the system is gas, electric, or a heat pump, the complexity of duct or electrical modifications, and add-ons such as zoning, air purifiers, or smart thermostats. We provide a detailed written quote so there are no surprises.
Will a new HVAC system really lower my energy bills, and by how much?
Yes. Replacing a 10-SEER air conditioner from 2008 with a 16-SEER2 model can cut cooling costs by roughly 30 %. Variable-speed heat pumps and 95 %-AFUE furnaces can save 20–40 % on heating costs. Many Duff homeowners also qualify for federal tax credits (up to $2,000) and local TVA rebates, further improving payback.
Do you offer warranties and financing on HVAC replacements?
All equipment we install comes with a manufacturer’s 10-year parts warranty when registered, plus our 1- or 2-year labor warranty. Optional extended labor protection up to 10 years is available. Financing choices include 0 % APR for 12-60 months, low-APR installment loans, and same-as-cash plans through trusted lenders. We also accept major credit cards and offer maintenance plans that keep your new system in peak condition.
