AC Maintenance
The spring tune-up that keeps a July breakdown from happening in the first place.
A dirty condenser coil can cost you a quarter of your capacity. Annual service catches the slow failures — weak capacitors, low charge, restricted airflow — while they are still cheap.
- Condenser and evaporator coil cleaning
- Refrigerant charge verification
- Capacitor and amp-draw testing
- Condensate drain clearing
Air conditioning maintenance at FortHouse means real readings — static pressure, refrigerant charge, amp draw — not just a filter swap and an invoice. Plainfield and Naperville homeowners get those numbers in writing before the first heat wave, not after a breakdown.
Booked in spring, before the first real heat wave, it's the difference between a scheduled tune-up and a July breakdown that turns into an emergency call.
What a real AC maintenance visit checks
Four things, every visit, not as an upsell:
- Condenser and evaporator coil cleaning — a dirty coil restricts heat transfer and can cost a system up to a quarter of its cooling capacity, gradually enough that it's easy to miss until the warning signs are obvious.
- Refrigerant charge verification — refrigerant runs in a sealed loop and doesn't get used up through normal operation, so a low charge always means a slow leak, not something that just needs a routine top-off.
- Capacitor and amp-draw testing — a weakening capacitor is one of the most common causes of a system that won't start at all, and it's catchable months before it actually fails.
- Condensate drain clearing — a clogged drain doesn't just risk water damage; it's also what trips a float switch and shuts the whole system down on the hottest day of the year.
What a $49 special is actually selling
A real AC tune-up costs what it costs because a technician's time, gauges, and an actual coil cleaning aren't free. A price far under that isn't a discount — it's a sales call with a wrench in hand, and the upsell is the actual product. If the invoice has no numbers on it afterward — no static pressure, no refrigerant readings, nothing beyond "looks fine" — nobody actually measured anything.
What AC maintenance costs
A real AC maintenance visit runs $89–$150 and takes 60–90 minutes — coil cleaning, refrigerant verification, capacitor and amp-draw testing, and condensate drain clearing, all included, not billed separately as they're "discovered."
When to book it: the spring window
Before the first real heat wave, not during it. Booking in spring means a technician catches a weak capacitor or a slow refrigerant leak while it's a scheduled fix, instead of finding out on the 95° day it finally fails — which is also the day every other AC in the area is failing too, and appointment windows stretch out accordingly.
Signs your AC needs more than maintenance
A tune-up catches slow failures while they're still cheap. It doesn't fix a system that's already failing. Ice on the coil or line set is one sign maintenance alone won't resolve. A system that's chronically undersized, a failing compressor, or a second repair in one season point toward a repair-or-replace conversation instead of a maintenance one.
What to check before you book AC maintenance
A few real questions separate a real visit from a filter check with an invoice:
- Does the price include all four checks, or does a lower price mean one gets quietly skipped?
- Does the invoice show real readings — static pressure, refrigerant charge, amp draw — or just "looks good"?
- Is the coil actually cleaned, not just glanced at?
- Who actually owns the company? We're family-owned, not backed by private equity — it changes whether the incentive is a thorough visit or a fast one.

Common questions
AC Maintenance — frequently asked.
How much does AC maintenance cost?
Most real AC maintenance visits run $89–$150 and include condenser and evaporator coil cleaning, refrigerant charge verification, capacitor and amp-draw testing, and condensate drain clearing. A price well under that range usually means one of those four gets skipped.
What's included in AC maintenance?
Four things at minimum: coil cleaning, refrigerant charge verification, capacitor and amp-draw testing, and condensate drain clearing — with real readings on the invoice, not just a visual check.
How long does AC maintenance take?
60–90 minutes for a thorough visit covering all four checks. A visit noticeably shorter than that is more likely a quick look-and-leave than a full inspection.
When should I get my AC serviced?
Spring, before the first real heat wave. Booking early catches a weak capacitor or slow refrigerant leak as a scheduled fix instead of a breakdown on the hottest day of the year, when every other AC in the area is failing too.
Is annual AC maintenance actually worth it?
Yes — a dirty condenser coil alone can cost a system up to a quarter of its cooling capacity, and it happens slowly enough that most homeowners never connect the gradual decline to a specific cause. Annual maintenance catches that and similar slow failures while they're still cheap.
What areas do you cover for AC maintenance?
Plainfield, Naperville, Oswego, Yorkville, Bolingbrook, Wheaton, Lisle, Minooka, Shorewood, and Aurora, plus the rest of Chicago's western suburbs. If you're just outside that list, call anyway — we make exceptions for a reasonable drive.
How we work
You call, we diagnose with real measurements, you get a flat written number before anything starts, then we fix it and put the post-repair readings on the invoice next to the originals. See the full four-step process.
