What to check monthly, seasonally, and annually, whether it's your home unit or a building full of them, and why skipping it costs more than the maintenance itself.
Rinse or replace filters every 2-4 weeks, book a professional cleaning every 3-4 months, and get a full inspection (coils, capacitor, drainage, refrigerant pressure) once a year. That single routine is what stands between a ₱799 cleaning and a ₱4,000+ compressor repair down the line.
For offices, condos, and commercial buildings running multiple units, the case is even stronger: unplanned downtime and emergency callouts cost far more than a scheduled maintenance contract, and tenants notice a broken aircon a lot faster than a well-maintained one.
Most aircon problems don't start as breakdowns. They start as a slightly dirty filter, a slow refrigerant leak, or a coil that hasn't been cleaned in a while, all things a routine maintenance visit catches early. Left alone, the same small issue eventually shows up as a "not cooling" call, and by then it's usually a bigger, more expensive fix.
The math is straightforward: a standard cleaning runs from ₱799, while a compressor repair, the kind of failure that regular maintenance is most likely to prevent, starts around ₱4,000 and climbs from there. Preventive maintenance also keeps units running efficiently, which matters directly for Meralco bills; a unit working harder to push air through a dirty filter or coil draws more electricity for the same amount of cooling.
A large share of the "aircon not cooling" repair calls referred through our technician network trace back to units that hadn't been cleaned in 6+ months. In most of these cases, the fix that actually got booked was a cleaning, not a repair, because the underlying issue was maintenance, not mechanical failure.
Some of this you can do yourself in a few minutes. Some of it needs a technician with the right tools. Here's the honest breakdown, adjusted for Metro Manila's climate and usage patterns rather than the "once a month" advice common in guides written for cooler countries.
| Task | Frequency | Who |
|---|---|---|
| Rinse or replace indoor filter | Every 2-4 weeks (daily-use units) | DIY |
| Clear debris around outdoor condenser | Every 2-4 weeks, more often in rainy season | DIY |
| Check remote is on Cool mode, not Dry/Fan | As needed | DIY |
| Standard cleaning (filter, coil rinse, drain check) | Every 3-4 months | Pro |
| Evaporator and condenser coil deep clean | Every 6-12 months | Pro |
| Refrigerant pressure and leak check | Annually, or if cooling weakens | Pro |
| Capacitor and electrical inspection | Annually, especially after brownouts | Pro |
| Drain line flush | Every 3-6 months, more often in rainy season | Pro |
Frequencies assume daily or near-daily use, typical for Metro Manila households and offices. Units used occasionally can stretch these somewhat.
For a single home unit, a missed cleaning means a slightly warmer room until you book a repair. For a building with a dozen units serving an office floor, a retail space, or a condo common area, the same missed maintenance means something more disruptive: units failing during peak heat, tenant or staff complaints, and technicians who are hardest to book exactly when demand is highest.
The core argument for a maintenance contract in a commercial setting isn't really about the repair bill, it's about predictability. A scheduled maintenance plan turns aircon costs into a fixed, budgetable line item instead of a series of unplanned emergency callouts, and it keeps a record of what was serviced and when, which matters if you're managing multiple units across a property or need documentation for facilities reporting.
This applies across offices, condominium common areas and individual units, retail spaces, and other commercial establishments with multiple aircon units to manage.
These are ArcticAir Manila's starting rates. Commercial and multi-unit pricing is quoted based on unit count and site access, since it scales differently than a single residential unit.
| Service | Starting Price |
|---|---|
| Standard cleaning (per unit) | ₱799 |
| Diagnostic check-up | ₱500 |
| Freon refill (leak check included) | ₱1,200 |
| Commercial / multi-unit maintenance plan | Custom quote |
See our full pricing guide for repair, cleaning, freon, and installation rates, or our maintenance plan page for details on scheduled service.
Every 3-4 months for units in daily or near-daily use, given Metro Manila's dust and humidity. Units used less frequently can typically stretch to every 6 months.
A check-up is a one-time diagnostic when something seems off. Preventive maintenance is the scheduled routine, filter checks, cleaning, coil and capacitor inspection, done on a calendar regardless of whether there's a visible problem yet.
Yes. A ₱799 cleaning every few months is small compared to the ₱4,000+ a compressor repair can cost, and most "not cooling" calls we see referred through our network trace back to skipped maintenance rather than genuine mechanical failure.
Reactive repairs across multiple units tend to cluster during peak summer months, when technicians are hardest to book and downtime is most disruptive to tenants or staff. A maintenance contract schedules service in advance, keeps costs predictable, and maintains a service record for each unit.
Filter rinsing and clearing debris from the outdoor unit are safe to do yourself. Coil cleaning, refrigerant checks, and electrical inspection require a technician with the right tools and training, attempting these yourself risks damaging the unit or, with electrical components, injury.
