Astello tune-ups cover the whole system: coils, filters, drain lines, electrical connections, output temperatures, a leak-detector sweep, and a test of every mode. If something looks off, we check pressures at the condenser and tell you whether it’s a leak or an undercharged system — not a guess. One visit fee, and it goes toward the work if your unit needs any.

Maintenance booking, on demand
Here’s the failure chain we keep finding in apartment units we service across the Capital Region, where tenants skip the filters: a clogged filter blocks airflow, so the coil can’t drain properly and stays wet. Water drips onto the fan. Meanwhile the drain line clogs, water sits in the drain pan — and now mold is growing in a machine that blows air into the room.
None of that is a defect. It’s maintenance nobody did. By the time it smells musty or the coil ices up, you’re paying repair prices for what a tune-up would have caught in an afternoon.
The same techs who install our systems handle the tune-ups.
Tell us about your home and we’ll put together a clear, no-pressure quote — usually within a day.
From the field
Landlord properties are where we see the worst of it, because nobody’s watching the filter month to month. The chain is always the same: a clogged filter blocks airflow, the coil can’t drain and stays wet, water drips onto the fan, the drain line clogs, and standing water in the pan starts growing mold.
If you’re a landlord: keep an eye on your units and don’t skip maintenance. A tenant won’t tell you the airflow got weak — they’ll tell you when it’s dead.
The chain, every time:
Cleaning your own unit is fine — until the wrong chemical meets the coil. Don’t use acids on coils or filters. The acidity damages components and can eat pinholes into the coil, and then you’re not cleaning a mini-split, you’re replacing part of it.
Regular soapy water or a proper coil cleaner is all it takes.
The safe list:
Your part vs. ours
Check the filters at the end of each month — more often if the unit is near the kitchen, because cooking residue and steam go straight through the filter, and more often if you have pets. Keep the area around the condenser clear. Keep an eye on the coil.
And the honest version: if your system runs fine and you keep up the simple stuff, you don’t need a tune-up. A fresh install usually doesn’t need one in its first year.
The leak-detector sweep, pressure readings at the condenser, electrical checks — and knowing whether a weak system is leaking or undercharged, two problems with the same symptoms and very different fixes.
Book us when something’s off, when it’s been a few seasons, or when the unit serves people who’ll never touch a filter.
A weak system might be a leak or an undercharged circuit — same symptoms, very different fixes. Our leak detector and condenser pressure readings tell us which, so you fix the actual problem once.
No issues, clean filters, clear condenser? We’ll tell you to keep your money. Maintenance is for systems that need it — and for landlords who can’t watch every unit.
The visit fee isn’t stacked on top of the bill: it goes toward the maintenance work if your unit needs any.
Tell us the system and the symptoms, if any. On-demand scheduling, 7 days a week.
Coils, filters, drains, electrical, output temps, a leak sweep, and every mode tested.
If something needs work, you get the finding and a flat price. The visit fee goes toward that work.
We show you the filter routine for your layout — the goal is fewer visits, not more.

Senville Pro ContractorCheck your own filters at the end of each month — more often near a kitchen (cooking residue and steam go through the filter) or with pets in the house. A professional tune-up makes sense every few seasons for a healthy system, sooner if airflow drops, something smells musty, or heating and cooling get weak.
Coils, filters, drain line and pan, electrical connections, output temperatures in every mode, and a leak-detector sweep. If anything reads off, we check pressures at the condenser to verify whether it’s a leak or an undercharged system.
There’s a set visit fee, and it goes toward the maintenance work if your unit needs any. You get the finding and a flat price before anything beyond the checkup happens.
The filters, yes — monthly, with regular soapy water. The one rule: never use acid-based cleaners on coils or filters. The acidity damages components and can create pinholes in the coil. Anything past filters and keeping the condenser area clear is our side of the line.
Almost always the moisture chain: a clogged filter blocks airflow, the coil stays wet, the drain clogs, and water sits in the pan growing mold. A tune-up clears the chain end to end — filter, coil, drain line, pan.
Usually not in the first year, and not while it runs clean and you keep the filters washed. The exception is rental units: if you’re a landlord, don’t skip maintenance — tenants won’t watch the filter, and we’ve serviced plenty of apartment units that failed exactly that way.
