FAQs
What does it mean that your technicians are NATE-certified, and why is that important for my HVAC replacement?
NATE (North American Technician Excellence) certification is the industry’s highest credential for HVAC professionals. A NATE-certified technician has passed rigorous, nationally recognized exams that verify real-world working knowledge of heating and cooling systems. For you, this means the installer understands Chattanooga’s specific climate challenges, follows best-practice load calculations, and completes the replacement to manufacturer specs, maximizing system efficiency, reliability, and warranty protection.
How do I know when it’s time to replace my HVAC unit instead of repairing it?
We typically recommend replacement when your system is 10–15 years old, requires frequent or costly repairs, or fails to keep your home comfortable despite rising energy bills. Our technicians perform a complete inspection—including refrigerant analysis, heat-exchanger integrity, and airflow diagnostics—then provide a repair-vs-replace cost comparison based on life-cycle operating costs, local utility rates, and potential energy savings.
What size HVAC system does my Chattanooga home need?
Proper sizing is critical in our humid subtropical climate. We conduct a Manual J load calculation that factors in square footage, insulation, window orientation, air-leakage rates, and even local elevation. Oversized equipment short-cycles, wasting energy and accelerating wear, while undersized units struggle on 90°F summer days. The result is a right-sized system that maintains comfort, controls humidity, and operates at peak efficiency.
How long does a typical HVAC replacement take, and will I be without heating or cooling?
Most residential replacements are completed in one day. We schedule the job when weather permits, arrive with all equipment and materials, remove your old unit, modify ductwork if needed, set the new condenser or air handler, recharge refrigerant, test-run the system, and clean up. Downtime is usually limited to 4–8 hours, and we always coordinate with you beforehand to minimize inconvenience.
Are there rebates or financing options available for a new high-efficiency system?
Yes. Tennessee Valley Authority (TVA) programs, EPB Energy Right, and manufacturer promotions can offer rebates of $150–$1,000 on qualifying heat pumps and high-SEER air conditioners. We handle the paperwork and verify eligibility. We also provide multiple financing plans—0% APR for 12–18 months or low fixed rates up to 10 years—so you can spread the investment over time while enjoying lower utility bills immediately.
What kind of warranties and maintenance should I expect after installation?
Most of our systems carry a 10-year parts warranty and a 1- to 3-year labor warranty when registered within 60 days. We also include a complimentary first-year maintenance visit. To keep warranties valid and system performance optimal, we recommend joining our Comfort Club: two precision tune-ups per year, priority service, and 15% repair discounts. Regular maintenance can extend equipment life by 20% and cut energy usage up to 30%.
