Your mini-split is more than a wall head — it’s a complete ductless system: the outdoor condenser, every indoor air-handling head, the refrigerant line set, filters, condensate drainage, and the controls that manage each zone. Our maintenance plans service the entire system, not just one unit, so a small issue in a single zone never drags down the rest. Spencer Heating and Air has serviced ductless systems in Lake Martin since the early 2000s, and we know exactly what they need to stay reliable. Whether you rely on your mini-split system for cooling through humid summers or heating through mild winters, regular maintenance keeps efficiency high and extends equipment life.
Get your ductless system inspected and serviced by our American Standard-certified technicians. We’ll identify any leaks, clean filters and coils, and verify that your system is ready for the season ahead. We serve Alexander City, Dadeville, Eclectic, and all Lake Martin communities with flexible scheduling.

Unlike central HVAC technicians, our team has deep experience with the unique maintenance needs of wall-mounted indoor units and outdoor compressors.
We understand refrigerant charging for mini-splits, coil cleaning without fin damage, and the condensation drain systems that are often overlooked on these units. Our technicians know the specific maintenance requirements that keep ductless systems running efficiently.
As an American Standard Customer Care Dealer with 55+ years in business, we’re factory-trained to service most mini-split brands and models.
We use genuine parts and manufacturer-approved procedures, protecting your equipment warranty. Our certification means we stay current with the latest ductless technology and service techniques.
Our maintenance program catches small issues—loose electrical terminals, refrigerant leaks, clogged filters—before they become expensive failures.
Homeowners who maintain their mini-splits spend 30–40% less on repairs over the system’s lifetime. We focus on prevention rather than waiting for breakdowns to occur.
Unexpected breakdowns happen. Even without a maintenance plan, we respond quickly to mini-split failures during cooling and heating seasons.
We carry common parts on our trucks to avoid return trips and restore comfort fast. Our Lake Martin location means quick response times throughout the region.
We’re based in Jackson’s Gap and serve all nine Lake Martin-area communities.
We understand the region’s humid summers, the wooded neighborhoods that shed leaves into outdoor units, and the seasonal timing of cooling and heating needs. Local knowledge makes a difference in service quality.
Efficient, even comfort depends on the outdoor condenser, every indoor air-handling head, the refrigerant line set, filters, condensate drainage, and the zone controls all working together.
A tune-up that only wipes down one indoor head misses where ductless problems actually start — a clogged condensate line, dirty filters choking airflow, low refrigerant across the line set, or a failing outdoor fan. We inspect and service the entire ductless system as one connected whole, so a small issue in a single zone never drags down comfort everywhere else.
Tap a problem to see how preventative maintenance keeps your system reliable.
Dirty filters restrict airflow, forcing the system to work harder and use more energy. Over time, restricted airflow can cause the evaporator coil to freeze and damage the compressor.
Prevention: Regular filter cleaning or replacement during maintenance visits keeps airflow optimal and prevents costly damage.
Maintenance Frequency
Monthly Check
Professional cleaning during annual service ensures optimal performance.
Algae, dust, and debris accumulate in the drain line, eventually blocking water flow. When the drain backs up, water can leak into your walls, causing expensive damage and mold growth.
Prevention: Annual drain line flushing with biocide solution prevents blockages and protects your home from water damage.

Annual Service
Biocide treatment prevents algae growth in humid climates.
Small refrigerant leaks often go unnoticed until cooling performance drops significantly. Low refrigerant forces the compressor to work harder and can cause permanent damage.
Prevention: Annual pressure testing detects leaks early when they’re inexpensive to repair, before compressor damage occurs.
Maintenance Frequency
Annual Testing
Pressure testing is the only reliable way to detect small leaks.
Dust and debris on the evaporator and condenser coils reduce heat transfer efficiency. The system runs longer to achieve the same cooling, driving up energy costs.
Prevention: Professional coil cleaning during maintenance restores efficiency and reduces energy consumption by 10–15%.

Annual Cleaning
Specialized cleaners and soft brushes prevent fin damage.
Vibration and thermal cycling can loosen electrical terminals over time. Loose connections create heat, reduce efficiency, and pose fire risks.
Prevention: Annual electrical inspection and tightening of all connections ensures safe, reliable operation.

Comprehensive inspection, cleaning, and testing to keep your ductless system running efficiently. Every Spencer maintenance visit follows the same thorough process—from initial assessment through final performance verification.
Our technician inspects both the indoor wall unit and outdoor compressor, checking for visible damage, debris, or leaks. We test basic operation—fan speed, mode switching, temperature response—and review your system’s service history. We note any unusual sounds, vibrations, or performance changes you’ve noticed since the last service.
We safely open the front panel of your wall unit and remove the filter. Reusable filters are cleaned and dried; disposable filters are replaced with high-efficiency alternatives. We inspect and gently clean the evaporator coil using specialized coil cleaner and soft brushes, removing dust and algae without damaging the delicate fins.
We clear debris from around the outdoor unit, then gently clean the condenser coil fins using specialized cleaner and a soft brush. We inspect all refrigerant line connections, electrical terminals, and bolts for tightness and corrosion. We verify the unit’s mounting is secure and vibration dampers are intact.
We access the condensation pan beneath the indoor unit and flush the drain line with a biocide solution to kill algae and prevent blockages. We test water drainage by pouring water into the pan and confirming it flows to the outdoor discharge point. This often-overlooked step prevents water damage to your walls.
We connect diagnostic gauges to measure refrigerant pressure on both sides of the system while it runs. We compare readings to manufacturer specifications and identify any leaks or charging issues. Once service is complete, we run the system through all modes to confirm correct operation and provide you with a written service report.
Our maintenance members enjoy priority scheduling, consistent system performance, and the confidence that comes from knowing a trained professional is keeping an eye on their equipment throughout the year.
What’s Included In Our Maintenance Plan?
We know that a new HVAC system or a major repair can be a significant investment. That is why Spencer Heating and Air works with trusted lending partners to make quality comfort accessible to every homeowner. We want you to make the best decision for your home — not the cheapest one because of budget pressure.
Why Consider Financing?
Hover over the section to see the full list. Regular maintenance keeps your ductless system efficient, reliable, and under warranty protection.
From energy savings to extended equipment life, professional maintenance delivers measurable benefits that far exceed the service cost. We’ll show you exactly what your system needs and explain how each service protects your investment.
Clean coils and proper refrigerant charge improve efficiency by 10–15%. A well-maintained mini-split uses less energy to deliver the same comfort, reducing monthly utility costs.
Regular maintenance prevents premature wear and component failures. Maintained mini-splits typically last 15–20 years versus 10–12 years for neglected systems.
Most manufacturers require documented maintenance to honor warranty claims. Our service reports provide the proof you need to protect your investment.
Preventative maintenance catches small issues before they become expensive failures. Maintained systems need 30–40% fewer unexpected repairs over their lifetime.
Clean filters and coils remove more dust, pollen, and allergens from your indoor air. Regular drain cleaning prevents mold and bacteria growth in the system.
Proper refrigerant charge and clean coils ensure your mini-split system delivers steady temperatures and humidity control throughout the cooling and heating seasons.
Maintenance is preventative—a scheduled annual (or semi-annual) inspection and cleaning that catches problems early and keeps the system efficient. A service call is reactive—you call when something breaks or isn’t working. Maintenance prevents the need for unexpected repairs and extends your system’s lifespan.
Contact us for a maintenance plan quote based on your system size and location. Our plans typically include one or two annual visits with full cleaning, inspection, and reporting. Schedule a consultation to discuss pricing options.
Yes. If your system has a reusable filter, you can vacuum it monthly during heavy-use seasons (cooling in summer, heating in winter). For disposable filters, replace every 1–3 months depending on dust levels in your home. Always turn off the system before removing the filter.
Signs include low cooling or heating output, frost on the outdoor coil in mild weather, or hissing sounds near the compressor. However, small leaks don’t always show obvious symptoms. A professional pressure test is the only reliable way to detect a leak—this is part of our standard maintenance visit.
The drain line connects the indoor unit’s pan to the outdoor discharge point. Algae, mineral deposits, dust, and pet hair accumulate inside, eventually blocking water flow. In Lake Martin’s humid climate, algae growth is especially common. Regular biocide treatment and annual flushing prevent clogs.
For mini-splits used primarily for cooling (most Lake Martin homes), schedule a cooling-system tune-up before peak cooling demand. If you heat in winter, schedule a heating-system tune-up instead. If you use your mini-split system year-round, twice-yearly service is ideal.
Skipped maintenance leads to reduced efficiency and higher energy bills. Refrigerant leaks go undetected and worsen, filters clog and restrict airflow, and condensation drains get blocked. Eventually, the compressor overworks and fails—a costly replacement that far exceeds the cost of annual preventative service.
Most manufacturer warranties require regular maintenance to remain valid. We provide written documentation of every service visit, which protects your warranty claims. Skipping maintenance may void your warranty on compressor repairs.
We service most major ductless brands, including American Standard, Mitsubishi, Gree, and others. We’re factory-trained on American Standard systems as a Customer Care Dealer. For less common brands, contact us to confirm coverage. Our training and experience span the full range of mini-split architectures.
A typical annual maintenance visit takes 1–2 hours, depending on system size and condition. Indoor unit cleaning and filter service takes about 30 minutes; outdoor unit inspection and cleaning takes 30 minutes; refrigerant testing and final verification takes another 30–60 minutes. We’ll give you an estimated timeline when you schedule.
