AC Maintenance
AC Maintenance & Tune-Ups in Brentwood, TN
Most breakdowns we see happen on the hottest afternoon or the coldest night of the year. A proper tune-up finds the weak links in spring, before July tests them.

Brentwood’s Heating & Air Pros
Tune-Ups That Catch Trouble Before July Does
Here's the pattern a local tech put plainly: cooling systems tend to fail on the hottest day and heating systems on the coldest day. It isn't bad luck. Capacitors, contactors, fan motors, and refrigerant charges work hardest under extreme load, so marginal parts that limped through mild weather give out when you need them most. A spring tune-up in Brentwood exists for one reason: to find those marginal parts in April instead of meeting them in July. Call (615) 759-0451 and we'll get your cooling system ready for the season.
What does our tune-up actually include? More than a quick once-over. We clean the condenser and evaporator coils, because dirty coils choke efficiency and freeze-ups start there. We measure the refrigerant charge and check superheat and subcooling rather than guessing. We test the capacitor and contactor under load, tighten electrical connections, and inspect for heat damage. We clear and flush the condensate drain line, check the safety switch, calibrate the thermostat, and verify airflow and temperature split. Then we tell you what we found in plain language, including anything that's wearing but not yet failed.
There's a warranty angle too. Most equipment manufacturers require documented professional maintenance to keep warranty coverage intact. Skipping tune-ups doesn't just risk a breakdown; it can leave you paying out of pocket for a part that should have been covered. We document every visit so your records are clean.
Brentwood homes add their own wrinkles. Mature-tree lots around Raintree Forest drop leaves and cottonwood into condenser coils. Large homes with multiple systems need each one checked, because the quiet guest-suite unit nobody thinks about is the one that floods a ceiling in August. And attic air handlers on wooded lots need their condensate drains cleared religiously, since a clogged drain over finished space is how ceilings get ruined. For the bigger picture on dust and moisture, see our indoor air quality services.
What's Included in Every Tune-Up
Coils cleaned
Condenser coil washed and evaporator coil inspected and cleaned as needed. Dirty coils are the number one silent efficiency killer we find.
Charge verified
Refrigerant levels measured with gauges and checked against superheat and subcooling targets. Low charge means we look for the leak, not just add refrigerant.
Electrical tested
Capacitors, contactors, relays, and wiring tested under load and tightened. Most no-start failures begin as electrical wear we can spot early.
Drain and airflow checked
Condensate drain flushed, safety switch tested, filter assessed, and temperature split measured to confirm the system is actually moving heat.

Maintenance the Way It Should Be Done
No scare tactics
If a part is wearing but has life left, we tell you it's wearing and let you decide. We don't manufacture urgency to fill a slow week.
Documented for your warranty
You get a written record of every visit: what was checked, what was found, what was done. Your manufacturer gets the paper trail it requires.
Scheduled around you
Mon through Fri 7AM to 7PM and Saturdays 8AM to 4PM. We confirm the window and show up in it.
What You Can Do vs. What We Should Do
There's real maintenance you can handle yourself, and there's work that genuinely needs a technician. Here's the honest split.
| Task | DIY-safe | Leave it to us |
|---|---|---|
| Change the air filter regularly | Yes, this is the single best DIY habit | |
| Keep vegetation 2 feet from the outdoor unit | Yes, and gently rinse coils with a hose | |
| Pour vinegar down the condensate drain access | Yes, monthly in cooling season helps | |
| Test capacitors or handle refrigerant | Yes, stored voltage and refrigerant need training | |
| Clean the indoor evaporator coil | Yes, it requires opening the air handler | |
| Diagnose weak cooling or odd noises | Yes, guessing gets expensive fast |

Your Questions, Answered
How often does my AC really need maintenance?
Once a year for cooling, ideally in spring before the heat arrives. If you run a heat pump for winter heating too, that system earns a fall check as well. Skipping years is how small, cheap problems become emergency calls.
What does your tune-up include?
Coil cleaning, refrigerant charge verification with superheat and subcooling checks, electrical testing of capacitors and contactors, condensate drain flush and safety switch test, thermostat calibration, filter assessment, and airflow and temperature split measurements. You get a written summary of everything.
Does maintenance actually prevent breakdowns?
It prevents most of the common ones. The majority of no-cool calls we run trace back to failed capacitors, dirty coils, clogged drains, or low refrigerant, all things a tune-up catches early. It won't stop every failure, but it shifts the odds heavily in your favor.
Will skipping maintenance void my warranty?
It can. Most manufacturers require documented annual professional maintenance to honor parts warranties. If a covered part fails and there's no maintenance record, the claim can be denied. We document every visit so you're covered.
Can I do any of the maintenance myself?
Absolutely. Change filters on schedule, keep the outdoor unit clear of vegetation and debris, and flush the condensate drain access monthly in summer. Leave refrigerant, capacitors, and anything inside the electrical panel to a technician.
When should I schedule my tune-up?
Spring, March through May, before Middle Tennessee heat settles in. That timing catches winter wear and gives us room to fix anything before you actually need cooling. Fall works for heat pump heating checks.
The ENERGY STAR maintenance checklist covers the same fundamentals we check on every visit, and it's a good reference between tune-ups.
