Why The AC Unit is running but not cooling in Toledo OH

Dirty or Clogged Filters

Dirty or clogged air filters can severely restrict the airflow in your AC unit. When the airflow is hindered, the system’s ability to circulate and cool the air efficiently is compromised. Over time, this can also cause the evaporator coils to freeze, diminishing the unit’s cooling capabilities.

Solution: Regularly check and replace your AC’s air filters. As a rule of thumb, inspect them every month, especially during peak usage, and replace them every 2-3 months or when visibly dirty.

Frozen Evaporator Coils

Your AC’s evaporator coils are responsible for absorbing the heat from the air. However, when airflow is restricted, or there’s a lack of refrigerant, these coils can freeze. A frozen coil cannot absorb heat, resulting in ineffective cooling.

Solution: If you suspect frozen coils, turn off your AC to allow them to defrost. Call professionals from All Seasons One Hour Heating & Air to inspect the system and identify the root cause.

Thermostat Malfunctions

Sometimes, the problem isn’t with the AC unit but the thermostat. If the thermostat isn’t calibrated correctly or is malfunctioning, it might not signal the AC to cool as it should.

Solution: Ensure the thermostat and the desired temperature are set to “cool” mode. If problems persist, consider replacing old thermostats or consult an expert for recalibration.

Refrigerant Issues

Refrigerant is the substance your AC uses to remove heat and humidity from the air. If a leak or your system is low on refrigerant, it won’t cool your home efficiently.

Solution: If you notice ice build-up, hear a hissing sound, or see refrigerant liquid near the unit, it’s best to call in professionals. Fixing refrigerant issues requires expertise to locate and seal leaks and recharge the system.

Dirty Condenser Coils

While evaporator coils absorb the heat, the condenser coils release it outside. If these coils in the outdoor unit become dirty or clogged with debris, they cannot remove heat efficiently, affecting the cooling process.

Solution: Regularly inspect the outdoor unit and ensure it’s clear from debris like leaves or grass clippings. Consider getting it professionally cleaned once a year.

Faulty Fans

Your AC unit has two fans: one that moves indoor air over the evaporator coils to cool it and another that blows air over the condenser coils to release the absorbed heat outside. The airflow and cooling process can be affected if either fan malfunctions due to a faulty motor, dirty blades, or lack of lubrication.

Solution: Listen for unusual noises, check for visible damages, and call in professionals if you suspect a fan problem.

Leaky Ducts

Leaky ducts are among many HVAC systems’ most common yet overlooked problems. When ductwork isn’t properly sealed or has deteriorated over time, it can lead to air leaks. These leaks not only compromise the efficiency of the heating and cooling system but can also spike energy costs, lead to uneven temperature distribution across rooms, and invite contaminants into the indoor air.

Solution: A thorough duct inspection by a professional is crucial. They can identify areas of leakage using specialized equipment and then seal them with mastic sealant or metal tape. For extensive damage, replacing sections of the duct might be necessary. By addressing leaky ducts, homeowners can ensure optimal system performance, healthier indoor air quality, and significant savings on energy bills.

Incorrectly Sized AC Unit

When it comes to air conditioning, size does matter. An incorrectly sized AC unit can cause a myriad of problems for homeowners. A team that’s too large can cool the room quickly, but it might not run long enough to dehumidify the space, leading to a cold but damp atmosphere. On the other hand, a unit that’s too small will continually run, struggling to reach the desired temperature, consuming more energy, and wearing out components faster. Both scenarios result in inefficiencies, increased energy bills, and an uncomfortable living environment.

Solution: Consult with All Seasons One Hour Heating & Air to determine the right AC size for your home, considering a replacement if your current unit is misfit.

Aged Unit

Much like any appliance, its efficiency tends to decrease as an AC unit ages. Older AC units need help maintaining consistent temperatures, often resulting in fluctuating comfort levels. Additionally, wear and tear on components increases the likelihood of malfunctions and breakdowns. An aged AC impacts comfort and can lead to higher energy bills due to its reduced efficiency. Regular maintenance can extend its lifespan, but there comes a time when replacing the old unit with a newer, more efficient model becomes the most economical and effective solution.

Solution: Consider a replacement if your unit is over 10-15 years old and constantly giving issues.

Blocked Vents and Registers

Blocked vents and registers seem like minor issues, but they can significantly hamper the efficiency of an HVAC system. When ducts are obstructed, the airflow becomes restricted, causing uneven cooling and the system to work harder than necessary. This results in rooms that are too warm or cold and increases energy consumption, leading to higher bills. Furthermore, the added strain on the HVAC system can reduce its lifespan. Ensuring vents and registers are free from obstructions like furniture or curtains is crucial for optimal performance.

Solution: Ensure all vents and registers are open and free from obstructions like furniture or drapes.

An air conditioner is integral to the comfort of our homes, especially during the sweltering Toledo summers. When it runs without cooling, the reasons range from simple fixes to more complex issues. Regular maintenance, timely inspections, and professional consultations can ensure these problems are caught early, providing a cool and comfortable environment in your home.
