FAQs
How do I know it’s time to replace my HVAC unit rather than repair it?
Several warning signs suggest it’s more economical to replace your system: frequent breakdowns (two or more major repairs in a year), escalating utility bills despite regular maintenance, inconsistent temperatures throughout the home, equipment age of 10–15 years for air conditioners or 15–20 years for furnaces, and the presence of outdated refrigerant such as R-22. Our Seymour-based Certified Comfort Specialists will perform a load calculation and cost-benefit analysis to confirm whether replacement is the smarter long-term choice.
What brands and efficiency ratings do your Certified Comfort Specialists recommend for Seymour’s climate?
We install nationally recognized brands—Trane, Carrier, Rheem, and Lennox—because they meet strict Energy Star and AHRI standards. For Seymour’s humid summers and cool winters, we typically suggest heat pumps or dual-fuel systems with SEER2 ratings of 15–20 and HSPF2 ratings of 8.1 or higher. These ratings strike the right balance between upfront cost and annual energy savings, often cutting utility bills by 25–40% compared with older equipment.
How long does a full HVAC replacement take, and will I be without heating or cooling during the process?
A standard like-for-like replacement usually takes one working day (6–8 hours). Complex jobs—adding duct modifications, zoning, or IAQ accessories—may extend to two days. You will be without heating or cooling only while we disconnect the old unit and set the new one (typically 2–4 hours). We schedule replacements during mild weather whenever possible, provide portable heaters or AC units if extreme temperatures are expected, and always leave your home secure and clean at the end of each day.
What warranties and guarantees come with a new system installed by your team?
All equipment carries a manufacturer’s limited parts warranty of 10 years when registered within 60 days. Our Certified Comfort Specialists add a 2-year labor warranty at no extra charge. Optional Comfort Club memberships extend labor coverage to 10 years and include bi-annual tune-ups. We also offer a 100% Satisfaction Guarantee: if the system does not perform as promised within the first year, we will repair, replace, or refund at no cost.
Do you offer financing or rebates for HVAC replacements in Seymour?
Yes. We partner with Wells Fargo, Synchrony, and TVA EnergyRight to provide financing options including 0% APR for 18 months or low fixed rates up to 120 months (subject to credit approval). TVA and local utility rebates can offset $200–$600 for high-efficiency heat pumps, and federal tax credits under the Inflation Reduction Act allow up to $2,000 for qualifying systems with ≥15.2 SEER2 and ≥7.8 HSPF2. Our team handles all paperwork so you capture every available incentive.
What steps do your Certified Comfort Specialists take to ensure proper sizing and installation?
We follow ACCA Manual J for load calculations, considering square footage, insulation, window orientation, occupancy, and duct losses. Manual S is used to match equipment capacity, and Manual D verifies duct design. Each installation includes: removal and eco-friendly disposal of the old unit; fabrication or sealing of ducts to ≤6% leakage; installation of vibration pads and anti-microbial drain pans; nitrogen flushing and vacuum evacuation to 500 microns for refrigerant lines; and final commissioning with static pressure, superheat, and subcool measurements logged in our digital records. This rigorous checklist guarantees peak efficiency, comfort, and manufacturer warranty compliance.
