How often should mini-split systems be professionally serviced?

We recommend pre-season maintenance before both heating and cooling seasons (typically fall and spring). This twice-yearly maintenance ensures peak performance year-round. If your system runs well, these two professional tune-ups provide excellent protection. Some systems in heavy use may benefit from additional maintenance visits.

What happens if I skip annual mini-split maintenance?

Without regular professional maintenance, several problems develop silently: Refrigerant charge gradually drops from small leaks you can't see. Coils get progressively dirtier, reducing heating and cooling efficiency. Electrical components deteriorate without regular testing. Filters get clogged if not changed. Your system works harder for less comfort while utility bills increase. Eventually, components fail requiring expensive repairs. Skip maintenance long enough, and you'll face premature system replacement.

How much does professional mini-split maintenance cost?

Mini-split maintenance investment varies based on system complexity. Maintenance plans spread costs over 12 months with affordable payments. Call 423-271-6515 for detailed information.

Can I maintain my mini-split system myself?

You can perform simple tasks like changing filters and keeping outdoor units clear of debris. Professional maintenance requires specialized equipment and expertise that addresses refrigerant charge measurement, electrical component testing, coil inspection, and detailed diagnostics. Professional service detects developing problems filters alone cannot identify.

What's the best time to schedule mini-split maintenance?

Fall (September-October) for heating season preparation and spring (March-May) for cooling season. Pre-season maintenance ensures systems are fully ready before peak demand periods. Scheduling before high-use seasons prevents problems when you need your system most.

Do I need maintenance if my mini-split is running fine?

Yes! Problems often develop silently without obvious symptoms. A system might seem fine while efficiency drops, refrigerant slowly leaks, and electrical components deteriorate. Professional maintenance detects these problems early when fixes are less expensive.

How long does a comprehensive mini-split maintenance visit take?

Typically 1-2 hours for comprehensive tune-up. Exact time depends on system condition, number of indoor units, cleaning needs, and any problems discovered during inspection.

What if maintenance discovers problems requiring repair?

We explain what we found, describe the problem in clear terms, show repair solutions, and provide transparent pricing. Some problems need immediate attention for safety or efficiency. Others can be scheduled later. We never pressure you into repairs and always give you full information to make informed decisions.

Does professional maintenance void my mini-split warranty?

No! Proper maintenance protects your warranty. Many manufacturers require regular maintenance to keep warranties valid. Our documented maintenance proves proper care and protects your warranty coverage.

Can you maintain mini-split brands other than Armstrong?

Absolutely! We maintain Armstrong, Samsung, Fujitsu, Mitsubishi, LG, and all other mini-split brands. We have expertise for any mini-split manufacturer and system configuration.

What should I do between professional maintenance visits?

Change filters monthly during active heating or cooling seasons. Keep outdoor units clear of debris. Rinse outdoor coils occasionally with gentle water spray. Ensure return air grilles aren't blocked. Monitor systems for unusual sounds or performance changes and call if you notice issues developing.

DIY Mini-Split Maintenance Between Professional Visits

Between professional maintenance appointments, perform these simple maintenance tasks:

Monthly Filter Checks During Active Seasons — Check filters monthly during heating and cooling seasons. Replace if gray, clogged, or dirty. Clean filters maintain efficiency and protect the evaporator coil.
Outdoor Unit Cleaning and Clearance — Trim vegetation around the outdoor unit. Remove leaves, sticks, twigs, and debris. Maintain 2-3 feet of clear space around the unit for proper airflow.
Gentle Condenser Coil Rinsing — Occasionally rinse the outdoor coil gently with a garden hose, being careful not to damage the delicate aluminum fins. Avoid high-pressure washing.
Return Air Monitoring — Ensure indoor return air grilles aren't blocked by furniture, curtains, or decorations. Return air blockage restricts system operation significantly.
Thermostat Battery Checks — If your thermostat operates on batteries, replace them yearly. Dead or dying batteries prevent proper system control.
Visual Monitoring for Issues — Listen for changes in normal operating sounds. Report unusual noises, decreased heating or cooling, or other changes immediately.
Drainage Observation — During humid weather, observe condensate drain discharge from the indoor unit. You should see steady water flow. Call immediately if drainage stops.
Indoor Unit Vent Inspection — Regularly check that the indoor unit's vents and discharge areas aren't blocked. Blocked vents reduce performance.

Preventing Mini-Split Problems Through Professional Maintenance

Regular maintenance prevents many common mini-split problems that lead to expensive repairs.

Refrigerant Leaks — Small leaks develop gradually and reduce cooling and heating capacity. Regular maintenance detects low charge before performance drops significantly.
Coil Problems — Dirty coils reduce heat transfer efficiency dramatically. Regular cleaning maintains optimal performance and prevents efficiency loss.
Electrical Component Wear — Capacitors and contactors deteriorate over time. Regular testing identifies failing components before complete failure occurs.
Reversing Valve Sticking — Stuck reversing valves prevent proper mode switching between heating and cooling. Regular maintenance identifies valve problems early.
Drain Line Blockage — Algae and bacterial growth clog drain lines. Professional cleaning and antimicrobial treatment prevent blockages and water damage.
Motor Wear and Failure — Worn motors lose efficiency and can fail suddenly. Regular maintenance testing identifies motor problems before failure.
System Imbalance — Temperature variations between zones indicate system imbalance. Regular maintenance detects and corrects imbalance problems.
Control and Sensor Issues — Thermostat and sensor problems prevent proper system control. Regular testing ensures proper operation.
