Signs your fan coil needs repair

Recognize these symptoms? Don't wait—fan coil problems usually worsen and can lead to water damage or complete failure.

No Heating or Cooling

Fan runs but air isn't warm or cold. Often caused by stuck actuators, failed valves, or building system issues.

Water Leaking

Water dripping from unit or ceiling below. Usually clogged drain or failed pan—needs immediate attention.

Strange Noises

Grinding, squealing, banging, or rattling sounds indicate worn bearings, loose parts, or valve problems.

Weak Airflow

Little or no air coming from vents. Often a clogged filter, failing motor, or blocked coil.

Musty Smell

Mold or mildew odor when running. Common in humid conditions—needs coil cleaning and drain treatment.

Won't Turn On

Unit completely dead. Could be electrical, thermostat, or motor failure. Check breaker first.

Common fan coil problems in Toronto condos

What causes fan coil problems in Toronto condos?

Condo fan coils face unique challenges that homes don't. Understanding why they fail helps you prevent problems and know when to call for service.

Age & Wear

Many Toronto condos have original fan coils from the 1990s-2000s. After 15-20 years, motors wear out, valves stick, and efficiency drops significantly.

Poor Maintenance

Skipped filter changes lead to dirty coils that can't transfer heat efficiently. Dust buildup strains motors and clogs drains.

Building Water Quality

Scale, sediment, and air in the building's water loop cause valve and actuator problems. This affects all units on the system.

Electrical Issues

Power surges, loose connections, and failing capacitors are common—especially in older buildings with dated electrical infrastructure.

Frequently asked questions

The most common reasons a condo fan coil doesn't blow cold air are: 1) The building hasn't switched to cooling mode yet (Toronto condos typically switch in late May/early June), 2) A dirty air filter blocking airflow, 3) A faulty actuator preventing the cooling valve from opening, 4) Low refrigerant in the building's chiller system, or 5) A failed blower motor. First check if your neighbors have cooling—if not, contact property management. If they do, call us for fan coil service.

Fan coil repair costs in Toronto typically range from $150-$500 for minor repairs like thermostat replacement or actuator service. Motor replacements cost $400-$800. Complete fan coil unit replacement ranges from $4,000-$6,500 for a single unit or $7,500-$11,000 for a double unit, including installation. Diagnostic service calls are usually $99-$150. We always provide a written quote before beginning any repair work.

Water leaking from a fan coil is usually caused by: 1) A clogged condensate drain line—the most common cause, especially in summer when condensation is heavy, 2) A cracked or overflowing drain pan, 3) A frozen coil thawing (often from airflow problems), or 4) A leaking valve or pipe connection. Water leaks should be addressed immediately to prevent damage to your unit and neighbors below. Turn off the fan coil and call for emergency service.

A well-maintained fan coil unit typically lasts 15-25 years. Many Toronto condos built in the 1990s and early 2000s still have their original fan coils, but efficiency and reliability decline significantly after 20 years. Signs it's time to replace include frequent repairs, poor temperature control, excessive noise, and rising energy costs. Annual maintenance can extend lifespan significantly.

Common causes of fan coil noise include: 1) Worn blower motor bearings (grinding or squealing), 2) Loose fan blade or debris in the blower (rattling), 3) Water hammer from valve issues (banging when turning on/off), 4) Vibration from loose mounting (humming or buzzing), or 5) Air in the water lines (gurgling). Most noises indicate a developing problem that will worsen—schedule service before it fails completely.

Residents can safely replace air filters and clean accessible surfaces, but most fan coil repairs require a licensed HVAC technician. Fan coils connect to building water systems under pressure, involve electrical components, and in many condos are building property requiring management approval for service. DIY attempts can cause water damage, void warranties, and violate condo bylaws. Always use a qualified professional for repairs.

Hudson HVAC offers 24/7 emergency response for fan coil issues. For active water leaks or complete heating/cooling failure, we typically dispatch a technician within 2-4 hours in the Toronto area. For non-emergency repairs, we usually schedule within 1-2 business days. Call (437) 448-0640 for immediate assistance.

Fan coils and heat pumps both provide heating and cooling in condos but work differently. A fan coil is a simpler unit that blows air across coils carrying hot or cold water from the building's central system—it has no compressor. A heat pump is a self-contained unit with its own compressor that extracts heat from a water loop. Heat pumps are more complex and expensive to repair. Many Toronto condos built before 2010 use fan coils, while newer buildings often have heat pumps.

Musty odors from your fan coil typically indicate mold or mildew growth on the coils, in the drain pan, or in the ductwork. This is common in Toronto's humid summers when condensation accumulates. The solution is professional coil cleaning, drain pan treatment, and in severe cases, antimicrobial treatment. Don't ignore musty smells—mold affects air quality and can worsen allergies and respiratory issues.

In most Toronto condos, yes. Fan coils typically connect to building systems (water risers, electrical panels) and may be considered common elements or require board approval. You'll usually need: 1) Written approval from property management or the board, 2) Proof of insurance from your contractor, 3) Scheduling for water shutdowns, and 4) Compliance with building standards for replacement equipment. Hudson HVAC handles this coordination for you.

If your fan coil runs but doesn't heat, common causes are: 1) The building hasn't switched to heating mode yet, 2) A stuck or failed actuator preventing the hot water valve from opening, 3) Air trapped in the water lines, 4) A faulty thermostat not calling for heat, or 5) Problems with the building's heating water supply. Check with neighbors first—if building-wide, contact management. If only your unit, call for fan coil service.

It depends on the repair. For a 20+ year old fan coil, minor repairs under $500 (thermostat, actuator, drain cleaning) are usually worthwhile. However, for major repairs like motor replacement ($400-800) or coil leaks, replacement often makes more financial sense. New fan coils are more efficient, quieter, and come with warranties. We'll give you an honest assessment of repair vs. replace for your specific situation.

Yes, mold growth in your fan coil can affect your health. When the unit runs, it circulates air across moldy coils and through your living space, spreading mold spores. This can trigger allergies, asthma symptoms, respiratory irritation, and headaches. People with compromised immune systems are at higher risk. If you notice musty smells when your fan coil runs, schedule a professional cleaning with mold remediation right away.

Fan coil freezing is usually caused by restricted airflow—most commonly a dirty filter or blocked return. When airflow drops, the coil gets too cold and moisture freezes on it. Other causes include low building chilled water temperature, a failing blower motor, or debris on the coil. Turn off the unit and let it thaw, check your filter, and if it happens again, call for service.

For most Toronto condos, every 3-6 months is recommended. Change more frequently (every 1-2 months) if you have pets, allergies, construction in your building, or live near a busy road. A dirty filter restricts airflow, strains your motor, reduces efficiency, and can cause freezing or overheating. If you can't remember when you last changed it, it's probably time.

An actuator is a small motor that opens and closes the valve controlling hot or cold water flow to your fan coil. When your thermostat calls for heating or cooling, the actuator moves the valve. Actuators fail due to age, electrical issues, or scale buildup in the water system. A failed actuator means your fan coil can't control temperature—it may be stuck heating, stuck cooling, or unable to do either. Actuator replacement is one of our most common repairs.

Short cycling—where the unit turns on for a few minutes then shuts off repeatedly—is usually caused by: 1) An oversized unit for the space, 2) A faulty thermostat, 3) Restricted airflow from a dirty filter, 4) A failing motor overheating and tripping on thermal protection, or 5) Electrical issues. Short cycling wastes energy and causes excessive wear. If resetting doesn't help, call for diagnosis.

In most cases, yes, but with limitations. Condo fan coils typically use simple on/off control, so smart thermostats can provide scheduling and remote access, but not the sophisticated learning features designed for furnace systems. The thermostat must be compatible with your fan coil's voltage (usually 24V or line voltage). We can recommend and install appropriate smart thermostats that work with your specific system.

For water leaks: Turn off the fan coil at the thermostat or breaker, place towels or containers to catch water, and notify building management and any neighbors below. For no heat emergencies: Use space heaters safely, close blinds for insulation, and layer up. For no cooling: Close blinds to block sun, use fans, and stay hydrated. In all cases, document the issue with photos for insurance or management records.

Yes. For rentals, we can work with either the tenant, landlord, or property manager—whoever is responsible for HVAC maintenance per your lease agreement. In most cases, the unit owner (landlord) is responsible for fan coil repairs. We can provide separate invoices for insurance claims and coordinate access as needed. Just let us know the situation when you book.
