A tune-up that actually checks things.
AC Maintenance & Tune-Up in Hermitage, Tennessee
Real maintenance is measurements, not a sticker on the unit: refrigerant pressures, capacitor health, coil condition, the drain line, and temperature split. You get the report, not just a receipt.

What's included
What's Included in This Visit
Every tune-up ends with a written report of what was measured. Demand the numbers.
Full System Inspection
Electrical connections, contactors, airflow, and thermostat calibration, checked end to end.
Refrigerant and Charge Check
Pressures measured against superheat and subcooling targets. Low charge triggers a leak hunt, not a blind top-off, and our gas charging and leak detection covers that.
Coil and Drain Cleaning
Condenser rinse, evaporator check, and the condensate line cleared. Humid Middle TN summers grow algae fast.
Filter and Airflow
Filter replaced, airflow verified, and temperature split measured so you know the system is moving heat properly.
Service overview
What a Tune-Up Actually Does
"What does a tune-up actually do, is it just marketing?" Homeowners ask it on r/hvacadvice every spring, and it's a fair question. A real tune-up is diagnostics with a wrench: refrigerant pressures, capacitor and contactor readings, coil condition, drain-line flow, and airflow measurements. A marketing tune-up is a 20-minute visit and a sticker.
Hermitage gives your system plenty to fight. Middle TN heat runs May through September, Nashville sits on allergy-capital pollen lists with rough months in April, June, and September, and spring storms pack outdoor condensers with leaves and cottonwood. That combination is why filters here rarely make it three months and why drain lines clog: a coil pulls gallons of moisture out of humid indoor air daily, and one algae plug trips the float switch and the whole system goes dark. We run Hvac Repair Pro tune-ups across Tulip Grove, the Villages of Riverwood, and the older brick ranches near Lebanon Pike, and the pattern holds everywhere: the systems that get a spring visit are the ones that don't die in July. Energy Star's maintenance guidance backs the same routine, filters, coils, and airflow first.
If a tune-up finds something broken, like a weak capacitor or a leaking Schrader valve, that's a repair, quoted separately, and you approve it before anything happens. And if the system quits on you before we arrive, our emergency AC repair line runs 24/7.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
What Happens During the Visit
The process flexes to the condition, but these checkpoints keep decisions clear.
Arrival Walkthrough
The tech listens first: hot rooms, noises, bills, anything that changed since last summer. Your observations point the inspection.
Inspection
Electrical, capacitors, contactor, airflow, thermostat calibration, and a look at the coil and drain line.
Cleaning
Condenser coil rinse, evaporator check, condensate line cleared, filter replaced.
Measurements and Report
Refrigerant pressures, temperature split, and readings written down. You keep a copy.
Recommendations
If anything needs repair, you see the options and prices before deciding. No pressure, no surprises.
Tools & methods
What Gets Measured
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Manifold Gauges
Refrigerant pressures read against superheat and subcooling targets, not guessed.
Digital Thermometers
Temperature split across the coil tells us whether the system is actually moving heat.
Capacitor Tester and Multimeter
Electrical health checked before the part fails, which is the whole point of the visit.
Wet-Vac and Brushes
Condensate drain lines cleared of algae and sludge so the float switch stays happy.
Use cases
When a Tune-Up Pays Off
The quiet wins. These never become emergency calls because the visit caught them first.
The Clogged Drain Surprise
A homeowner called convinced the AC had died. The float switch had tripped on a clogged drain line. Twenty minutes with a wet-vac, plus the vinegar-down-the-drain monthly tip, and the system was back.
The Weak Capacitor
Readings during a spring visit showed the capacitor drifting out of spec. Replaced on the spot. That unit would have quit on a July night without the visit.
Problems we solve
Small Problems a Tune-Up Catches
Caught early, these are routine. Caught late, they're the 10 p.m. call.
Weak capacitors and pitted contactors
Electrical wear shows on a meter before it shows as a dead system. We flag it and quote it.
Dirty coils starving airflow
Cottonwood, grass clippings, and pollen pack condenser coils. A rinse restores the breathing room.
Clogged drains tripping the float switch
The system "dies" over a plugged line. Clearing it is quick once you know where to look.
Pricing process
What a Tune-Up Typically Costs
$150 - $300 depending on scope
System size and type
Heat pumps get twice-yearly visits since they heat too. Larger systems take more time.
Coil and drain condition
Years of skipped maintenance mean heavier cleaning. The visit report shows exactly why.
Repairs found during the visit
A weak capacitor or leaking valve is a separate repair, quoted and approved by you first.
What to expect
What to Expect When You Book
STEP 1
The call
A live dispatcher books your spring or fall visit and asks about hot rooms, noises, and anything that changed. Your observations guide the inspection.
STEP 2
The visit
The tech inspects, cleans, and measures, then hands you the written report with every reading. Ask questions; the numbers are yours.
STEP 3
The decisions
If repairs are needed, you see the options and prices before anything is approved. Nothing gets done on a guess.
What does an AC tune-up actually do? Is it just marketing?
It's a fair question. A real tune-up measures things: refrigerant pressures against superheat and subcooling targets, capacitor and contactor health, temperature split across the coil, coil condition, and the condensate drain. Ask for the written report. A tune-up done in 20 minutes with no numbers was marketing.
How often should I service my AC in Middle Tennessee?
Once a year, in spring, before the May heat arrives. If you run a heat pump, twice a year, spring and fall, since it heats too. Middle TN humidity means drain lines and coils need that regular attention.
How often should I change my air filter?
Every 1-3 months, and monthly if you have pets or the house is dusty. Nashville's pollen seasons in April, June, and September clog filters fast, and a dirty filter is the top cause of frozen coils and weak airflow.
Are HVAC maintenance plans worth it?
They can be, for the right household: priority scheduling during heat waves, discounts on repairs, and a paper trail for manufacturer warranty requirements. Ask what the plan actually includes before signing.
What's the difference between a tune-up and a repair?
A tune-up is preventive: inspection, cleaning, and measurements. A repair fixes something broken. If the tune-up finds a weak capacitor, that's quoted as a separate repair, with your approval first.
