Common Emergency Air Conditioner Problems

Sometimes, your air conditioning system gives you warning signs before shutting down. Many emergency AC calls involve sudden system failure or performance loss. Let’s take a look at air conditioner malfunctions that indicate it’s time to contact an HVAC technician.

The most frequent emergency air conditioning issues include:

AC not cooling or blowing warm air: This often signals low refrigerant, a failing compressor, or a frozen evaporator coil. Running the system without addressing the root cause can cause further component damage.
Frozen evaporator coils: Restricted airflow or low refrigerant levels cause coils to ice over, blocking cooling entirely. A frozen coil will not resolve itself – continued operation can damage the compressor, the most expensive component in your system.
Refrigerant leaks: Refrigerant loss reduces cooling capacity and can pose environmental and health risks. Leaks must be repaired by a licensed HVAC technician before refrigerant is recharged.
Electrical component failure: Faulty capacitors, contactors, or wiring can cause the system to fail to start or shut down unexpectedly. These components can also present a fire risk if left unaddressed.
Compressor failure: The compressor is the heart of your AC system. When it fails, the unit cannot produce cool air. Early warning signs include hard starting, loud clicking, or warm air despite the system running.
AC unit will not turn on: This can result from tripped breakers, a failed thermostat, or a safety shutoff triggered by overheating. A technician can pinpoint the cause and restore operation quickly.
Burning smell from outdoor unit: A burning odor from the unit often indicates overheating motors or electrical components. Shut the system off immediately and call for emergency service – do not continue to run the unit.
Water leaking from AC system: AC systems produce condensation, but visible water pooling indoors typically indicates a clogged condensate drain or a frozen coil that has begun to thaw. Left untreated, water damage can spread quickly.

Ignoring these warning signs can lead to higher repair costs or complete system replacement. Immediate service protects your equipment, your home, and your family’s comfort.

Common Emergency Heating Problems

Heating emergencies often begin with unusual noises, unexpected system shutdowns, or a complete loss of heat. Recognizing the signs early can reduce repair costs and prevent secondary damage.

The most frequent emergency heating issues include:

Furnace not producing heat: This is the most urgent heating emergency, particularly during extreme cold. Common causes include a tripped breaker, failed ignitor, clogged filter restricting airflow, or a faulty gas valve. Do not attempt to diagnose a gas-related issue yourself – call a licensed HVAC technician.
Pilot light or ignition failure: On older systems, a pilot light that will not stay lit may indicate a faulty thermocouple. On modern systems, electronic ignition failure prevents the furnace from starting. Both require professional diagnosis.
Heat pump not switching modes: If your heat pump is running but not heating or cooling effectively, the reversing valve – which switches between heating and cooling modes – may have failed. This is a component replacement job.
Boiler leaks or pressure loss: A boiler losing pressure or showing visible leaks requires immediate attention. Continuing to operate a leaking boiler can cause significant property damage and may void your system warranty.
Repeated system cycling: Short cycling – where the system turns on and off frequently – strains components and drives up energy costs. It typically points to thermostat issues, an oversized system, or a failing heat exchanger.
Burning odors from vents: A burning smell when the heat turns on for the first time each season can be normal dust burning off. However, a persistent burning odor – especially one that smells like electrical burning or melting plastic – requires immediate service.
Loud banging or grinding sounds: Banging can indicate delayed ignition or loose components inside the furnace. Grinding often points to worn blower motor bearings. Both should be evaluated by a licensed HVAC technician before the system is run further.
Thermostat malfunction: A thermostat that is not communicating properly with your heating system can cause no-heat calls that are actually simple fixes. A technician can confirm whether the issue is the thermostat or the heating system itself.

Prompt repair prevents extended downtime and protects your heating system from further damage. We also recommend scheduling annual maintenance to keep your system operating efficiently and catch potential issues before they become emergencies.

Emergency Plumbing Services

Plumbing emergencies can cause immediate property damage and serious health risks. When water spreads fast, or sewer backups require urgent attention before contamination spreads, you need an experienced emergency plumber. Horizon’s licensed plumbers are available 24/7 for emergency plumbing repairs to stop damage, restore function, and protect your home.

We offer the following emergency plumbing services to homeowners:

Common Emergency Plumbing Problems

Emergency plumbing calls typically involve active leaks, loss of water service, or system backups that cannot wait. Here are the most frequent issues our plumbers respond to around the clock.

The most frequent emergency plumbing issues include:

Burst pipes: Freezing temperatures, old galvanized pipes, or sudden pressure changes can cause pipes to burst, releasing large volumes of water rapidly. Shut off your main water supply immediately and call for emergency plumbing service. Every minute of delay increases water damage and restoration costs.
Sewer line backups: If multiple drains in your home are backing up simultaneously, the problem is likely in the main sewer line rather than an individual drain. Sewer backups carry bacteria and waste – this is a health emergency, not just an inconvenience.
Clogged and overflowing toilets: A single overflowing toilet is typically a localized clog. Multiple toilets backing up at once points to a main line issue. Either scenario requires immediate attention to prevent water damage to floors and subfloor.
Drain blockages: Severe clogs in kitchen or bathroom drains can cause wastewater to back up into your home. Hydro jetting or drain rodding can clear the blockage quickly and restore normal flow.
Water heater leaks: A leaking water heater can release significant water before being noticed, particularly in basements or utility rooms. Leaks can stem from a failed pressure relief valve, corroded tank, or loose connections – all requiring prompt repair or replacement.
No hot water: A complete loss of hot water indicates either a failed heating element (electric), pilot light issue (gas), or in tankless systems, a flow sensor or burner failure. Our plumbers carry parts for most major brands to restore hot water in a single visit.
Slab leaks: Leaks in pipes running beneath your home’s concrete foundation are serious. Signs include warm spots on floors, unexplained increases in your water bill, or the sound of running water when no fixtures are in use. Early detection prevents foundation damage.
Gas line leaks: If you smell gas in your home, leave immediately and call your gas utility and emergency services before calling a plumber. Once the area is safe, Horizon’s licensed gas fitters can locate and repair the leak. Never attempt to address a gas leak yourself.
Sump pump failure: A sump pump that fails during heavy rain can result in significant basement flooding within hours. If your sump pump is not running or not keeping up with water intrusion, emergency service is critical.
Main water line breaks: A break in the main water line supplying your home will result in no water service or significantly reduced pressure. This requires immediate excavation or trenchless repair to restore service.

Fast response limits water damage and reduces restoration costs. Call Horizon the moment you notice a plumbing emergency – our team dispatches immediately.

Emergency Electrical Services

Electrical problems can present serious fire and safety hazards that escalate quickly. If you notice burning smells, sparking outlets, repeated breaker trips, or a partial loss of power, immediate service is critical. Do not ignore electrical warning signs – they rarely resolve on their own and often indicate an underlying issue that poses real fire risk.

Horizon provides licensed 24/7 emergency electrician services to diagnose and correct hazardous electrical conditions throughout Delaware, New Jersey, Pennsylvania, and Maryland.

We offer the following emergency electrical services to homeowners:

Common Emergency Electrical Problems

Many emergency electrical calls involve overheating components, power failures, or safety hazards that require immediate attention by a licensed electrician. Here are the most frequent issues our emergency electricians are dispatched to.
The most frequent emergency electrical issues include:

Burning smell from panel or outlets: A burning odor near your electrical panel or outlets is a serious warning sign. It often indicates overheated wiring, a failing breaker, or arcing – all of which are direct fire hazards. Turn off the affected circuit if it is safe to do so and call immediately.
Repeated breaker trips: A breaker that trips repeatedly is not just an inconvenience – it is a signal that the circuit is being overloaded or that there is a fault in the wiring or a connected appliance. Continuously resetting a tripping breaker without addressing the cause increases fire risk.
Partial or total power loss: Sudden loss of power to part or all of your home may indicate a tripped main breaker, a utility issue, or a fault in your panel. If neighboring homes have power and resetting your main breaker does not restore service, you have an internal electrical issue requiring professional diagnosis.
Sparking or exposed wiring: Any visible sparking – whether at an outlet, switch, or inside your panel – requires emergency service. Exposed wiring presents an immediate shock and fire hazard. Do not attempt to handle exposed wiring yourself.
Electrical shocks from fixtures: Receiving a shock when touching a light switch, outlet, or appliance indicates faulty wiring, a missing ground, or a damaged fixture. This is not a normal occurrence and should be evaluated by a licensed electrician immediately.
Water exposure to electrical systems: Flooding, roof leaks, or burst pipes that reach electrical panels, outlets, or wiring create an electrocution risk. Do not enter standing water near electrical components. Our licensed electricians can safely assess and restore electrical systems after water intrusion.
Flickering lights throughout home: Lights flickering in a single room may indicate a localized loose connection. Flickering throughout the entire home, however, often points to a failing main breaker, a loose service entrance connection, or a utility-side issue – all of which warrant immediate professional electrical evaluation by an electrician.
Storm-damaged service lines: Downed or damaged service lines connecting your home to the utility grid require the utility company to restore the external connection – but the internal point of connection and your panel may also need inspection and repair by a licensed electrician before power is safely restored.

Addressing these issues quickly reduces fire risk and protects your home and family. Horizon’s licensed electricians are available around the clock to diagnose and resolve electrical emergencies throughout our service area.
