FAQs
What does it mean that your technicians are NATE-certified?
NATE (North American Technician Excellence) certification is the HVAC industry’s most recognized credential. To earn it, our technicians must pass rigorous, proctored exams that test real-world knowledge of heating, cooling, and refrigeration systems. When you schedule a replacement with us, you’re getting specialists who have demonstrated expertise, follow industry best practices, and stay current through continuing education.
How do I know if it’s time to replace my HVAC unit rather than repair it?
A rule of thumb is to consider replacement when your system is over 10–12 years old, requires frequent or costly repairs, or fails to maintain comfort and efficiency. Our Lake City team will perform a detailed load calculation, inspect system health, and compare the long-term costs of repair versus replacement so you can make an informed decision.
How long does a typical HVAC replacement take in Lake City homes?
Most residential change-outs can be completed in one working day. This includes removing the old equipment, installing the new air handler and condenser, updating line sets or duct transitions if needed, charging the system with refrigerant, and performing a full start-up and safety check. Larger homes or added ductwork modifications may extend the project to two days.
Will a new HVAC system really save me money on energy bills?
Yes. Modern systems have SEER2 (Seasonal Energy Efficiency Ratio) ratings that are 20–40% higher than units installed 10–15 years ago. That translates to lower monthly utility costs. We’ll size your new equipment correctly for Lake City’s humid subtropical climate, verify duct integrity, and offer high-efficiency options—often delivering payback in 3–5 years through energy savings alone.
What brands and financing options do you offer for replacements?
We install leading manufacturers such as Trane, Lennox, Carrier, and Rheem, and our NATE-certified pros are trained directly by the factory. For budgeting, we partner with local credit unions and national lenders to provide 0% APR promotional financing, low monthly payment plans, and rebates from utility companies and manufacturers where available.
Is there any warranty or maintenance support after the installation?
Absolutely. All new systems come with a 10-year parts warranty and up to a 10-year labor warranty when you enroll in our Comfort Club. Club members receive bi-annual tune-ups, priority scheduling, and discounted repairs, ensuring your investment stays protected and operates at peak performance in the Lake City climate.
