FAQs
How do I know it’s time to replace my HVAC unit in Duff rather than repair it?
Most systems in Duff last 12–15 years. If your unit is nearing this age, requires frequent or costly repairs, produces uneven temperatures, or causes energy bills to rise, it’s usually more economical to replace it. A certified technician can perform a load calculation and cost-benefit analysis to confirm.
What industry-leading techniques do you use during an HVAC replacement?
We follow ACCA Manual J, S, and D guidelines for precise load calculations, employ high-static pressure duct testing, use nitrogen and a vacuum pump during refrigerant line brazing, and perform digital airflow balancing. These best practices ensure your new system is properly sized, sealed, and optimized for Duff’s humid continental climate.
How long does a typical HVAC replacement take in Duff homes?
Most residential replacements take 4–8 hours once equipment is on site. The timeline can extend to 1–2 days if duct modifications, electrical upgrades, or smart thermostat integrations are needed. We provide a written schedule before work begins so you know exactly what to expect.
Will a new HVAC system really lower my energy bills?
Yes. Replacing an older 8–10 SEER unit with today’s 15–20 SEER equipment can cut cooling costs by up to 40%. Variable-speed compressors and ECM blower motors further reduce electricity use by adjusting output to Duff’s changing temperatures rather than running at full capacity all the time.
What warranties or guarantees come with a new HVAC unit?
Most leading manufacturers offer 10-year parts and compressor warranties when the system is registered within 60 days. We add a 2-year labor warranty and a one-year 100% satisfaction guarantee. Annual maintenance plans are available to keep the warranty valid and your system performing at peak efficiency.
Do you offer financing or rebates for HVAC replacements in Duff?
Absolutely. We partner with local banks and national lenders to provide 0% APR plans for up to 18 months or low monthly payments for terms up to 120 months. Qualifying ENERGY STAR systems may also earn utility rebates and federal tax credits; we handle the paperwork so you capture every available incentive.
