Set fan coil maintenance frequency using equipment instructions, condition and the building’s agreed program. Confirm which tasks the building visit covers and whether additional work is chargeable. The checklist below helps compare basic and comprehensive scopes.
1. Dirty Filters
Replacing dirty filters is essential for maintaining efficient airflow and preventing excess strain on the blower. Clogged filters force your system to work harder, which can reduce its lifespan and increase energy consumption. Keeping filters clean also helps improve indoor air quality.
2. Thermostat Issues
A malfunctioning thermostat is a common HVAC issue that can disrupt temperature control, causing continuous blower operation or inaccurate temperature readings. Check the thermostat settings and batteries before calling for a repair, as sometimes user error or low batteries are the culprits. For best results, refer to the manufacturer’s manual to ensure proper use and understanding of your thermostat.

3. Actuator Problems
The actuator, a motorized valve that regulates hot or cold water flow through the coil, is vital for heating and cooling functions. If the actuator malfunctions, you may experience inadequate temperature control or excessive noise. Ensuring this component functions correctly is key during your semi-annual fan coil maintenance.

4. Lack Of Airflow & Noisy Fans
Insufficient airflow can reduce your system’s efficiency and cause the blower to operate noisily. Older fan coils may have blowers in need of replacement. Regular vacuuming and cleaning of the blower housing are recommended for better indoor air quality and noise reduction. Unusual noises, such as squealing, can indicate worn bearings in the blower motor.

5. Rusted Drain Pans
The drain pan collects condensation, especially during humid months. Over time, rust can accumulate, compromising its ability to hold water, leading to potential water damage. Excess sediment buildup can also clog the pan. Units older than 20 years may need refurbishment or replacement to avoid recurring issues.

6. Drain Hose
During maintenance, a qualified technician should inspect the drain hose for restrictions, wear and cracks. Cleaning methods must suit the equipment and shared drainage arrangement; replace damaged hoses and test drainage after servicing.
7. Dirty Coils
Dirty coils reduce your system’s efficiency by blocking heat transfer. Regular vacuuming of coils is recommended to maintain optimal performance and prevent energy waste.
8. Faulty Water Alarm Sensor
Modern fan coil units come equipped with water sensors to detect leaks. Testing these sensors annually is essential to ensure they function correctly and protect your condo from potential water damage.
9. Mould & Fiberglass Insulation
Mould growth is a common concern in condo fan coils, especially in units over 15 years old. As insulation deteriorates, mould can become more prevalent. For older systems, consider consulting a professional for mould remediation or explore retrofitting options if the unit is nearing the 20-year mark.Airborne fibreglass particles can cause skin irritation, itchiness and rashes. When inhaled, these tiny particles can cause and trigger other respiratory problems such as lung disorder, nosebleed, coughing and sore throat.
10. Shut-Off Valves
Each fan coil unit has supply and return isolation valves to control water flow. These valves are critical during repairs or replacements, allowing for water shut-off. Sometimes, valves may appear closed but still allow water flow. To avoid service disruptions for neighboring units, test these valves during maintenance.
The Importance Of Regular Condo HVAC Maintenance
Installing condo HVAC systems is a substantial investment, and regular maintenance is key to protecting this investment. Skipping maintenance can lead to costly repairs, erratic performance, and breakdowns, which disrupt daily life and potentially affect neighboring units. Scheduled preventive maintenance not only saves you money but also provides peace of mind by keeping your HVAC system running efficiently, minimizing unexpected disruptions.
