Swapping a single component takes about 4–8 hours; a complete system replacement typically runs 8–14 hours — usually one long day. If ductwork needs repairs or replacement, plan on 2–5 days. We give you an accurate timeline at the inspection.

Not automatically. Ducts under about 15 years old that are sound, sealed and properly sized can stay — ideally professionally cleaned before the new system runs. Ducts that are older, leaking, crushed or undersized will choke a new unit. We assess yours at every inspection — and unlike pure HVAC installers, we can clean or replace them ourselves.

The ballpark is about 20 BTUs per square foot, but real sizing needs a load calculation — ceilings, insulation, windows, sun exposure. Oversized units short-cycle and leave the house humid; undersized units run non-stop and never catch up. We calculate, we never guess.

About 10–15 years here, versus 15–20 nationally — Texas systems run hard seven to nine months a year. Annual maintenance and a correct installation are what push a unit to the top of that range.

Less than you’d think. Premium brands use sturdier components, but industry pros estimate installation quality drives up to 80% of real-world performance and lifespan. We install all brands — what we never compromise is the sizing, the refrigerant charge and the airflow.

Every installation is backed by our 10-year warranty, with all work performed by licensed HVAC professionals. Ask about our twice-a-year maintenance plan to keep the system at peak efficiency for the long haul.
