Louisiana HVAC systems work harder than almost any others in the country — we cool for seven months, heat for three, and fight humidity year-round. A twice-yearly professional tune-up catches the small stuff (dirty coil, weak capacitor, loose contactor) before it takes down the whole unit in July at 4 PM. Over the life of a system, most homeowners who maintain save 2–3x what they spend on maintenance.
What's included in a real tune-up
25-point inspection
We check every capacitor, contactor, relay, motor, refrigerant pressure, superheat/subcool, airflow, and static pressure — not a 'look, wipe, leave' visit.
Coil cleaning inside & out
Dirty coils are the #1 efficiency killer. We pull panels, clean the outdoor condenser coil, and inspect (and clean, if reachable) the indoor evaporator coil.
Refrigerant check
We verify the charge is correct using actual pressures — under/overcharge kills compressors. If we find a leak, we tell you and quote — we never just top off.
Drain line flush
Louisiana humidity means your condensate line runs wet and constantly. We flush it to prevent the #2 cause of summer emergency calls: water leaks from a clogged line.
Electrical tightening
Heat cycles loosen electrical connections. Loose connections cause burn-outs. We tighten every screw and terminal, every visit.
Safety & combustion check (heating)
On gas systems, we verify combustion, test the heat exchanger for cracks, and check every safety switch. Peace of mind is the real deliverable.
Our process — four steps, zero surprises
- Book in two minutes. Online or by phone. Confirmation within the hour.
- Text when we're rolling. Tech photo, live ETA, and a real window — not a 4-hour guess.
- Diagnose and quote flat. We walk you through what we found, show you the part, and quote in writing. Nothing starts without a yes.
- Fix it and back it up. Most repairs done in one visit. Every job carries a workmanship guarantee.
How much does an HVAC tune-up cost?
A single AC or heating tune-up is $129 for non-members. Care Club members get two tune-ups a year included, plus priority scheduling, waived diagnostic fees, and 15% off repairs — from $16/month per system.
