AC Running But Not Cooling? Get Expert Repair Service

Few things are more uncomfortable than feeling warm air blow from your air conditioning vents when you expect a blast of cool relief. When your AC system is running but simply not cooling your home properly, it's a clear sign that something isn't right. This isn't just an inconvenience; it can lead to wasted energy, higher utility bills, and potential long-term damage to your system if ignored.

You're not alone in experiencing this frustrating issue. Many homeowners face the problem of an AC unit that seems to be working but fails to deliver the cool comfort their home needs. The good news is that our experienced technicians specialize in diagnosing and fixing exactly these kinds of problems quickly and effectively.

Why Your Air Conditioner Isn't Cooling Properly

An air conditioner that's running but not cooling the house can have various causes, ranging from simple issues you might check yourself to more complex mechanical or refrigerant problems that require professional expertise.

Here are some common reasons your AC might not be cooling:

  •  Dirty Air Filter: The simplest and most common culprit. A clogged filter restricts airflow across the evaporator coil, preventing it from absorbing heat effectively and potentially causing the coil to freeze. Checking and changing your Air Duct filter regularly is crucial preventative maintenance.
  •  Thermostat Issues: Incorrect settings (like being set to "Fan Only") or a malfunctioning thermostat can prevent the AC from calling for cool air.
  •  Frozen Evaporator Coil: If the coil freezes (often due to poor airflow from a dirty filter or duct issues, or low refrigerant), it can't absorb heat. You might see ice buildup on the indoor unit. This requires professional diagnosis to address the root cause safely.
  •  Low Refrigerant: Refrigerant is the substance that absorbs heat from your home. Low levels are usually due to a leak, which reduces the system's cooling capacity significantly. Refrigerant leaks are harmful to the environment and require a certified technician to locate and repair the leak and then properly recharge the system.
  •  Dirty Condenser Coils: The outdoor unit's coils release heat from your home into the outside air. If these coils are covered in dirt and debris, they can't dissipate heat efficiently, leading to poor cooling and potential system overheating. Professional cleaning is often necessary.
  •  Blocked Vents or Ducts: Restricted airflow in your HVAC ductwork due to closed vents or blockages can prevent cool air from reaching rooms, making your home feel unevenly cooled or not cool enough.
  •  Blower Motor Problems: The indoor blower fan pushes cooled air through your ducts. If it's malfunctioning or weak, airflow is reduced, impacting cooling throughout the house.
  •  Compressor Issues: The compressor is the heart of the AC system, circulating refrigerant. If it fails or malfunctions, the system won't be able to cool the air. Compressor problems typically require professional assessment and repair or replacement.
  •  Electrical Problems: Faulty capacitors, contactors, or wiring can prevent essential components like the compressor or blower motor from running correctly, impacting cooling. Electrical work should always be handled by a trained technician for safety.
  •  System is Undersized or Aging: An AC unit that's too small for your home or nearing the end of its lifespan may struggle to cool effectively, especially during peak heat.

When to Call a Professional

While checking your air filter and thermostat settings are simple steps you can take, most reasons for an AC not cooling properly require professional attention. Issues involving refrigerant, electrical components, frozen coils, strange noises or smells, or any problem you can't easily identify should prompt a call to an HVAC professional. Attempting to fix these complex problems yourself can be dangerous and may cause further damage to your expensive system.

Customer Reviews

We recently moved to Florida and needed major repairs to our church. After researching several companies, I went with Sunstate and I’m so thankful I did. Joe came out and provided us with the information necessary to make an informed decision and provided a reasonable estimate. We had a new unit installed, duct work repaired, and new thermostat installed. If you’re reading this review and wondering who to trust for your AC needs, please call Sunstate.

Great job replacing both the condensing unit and air-handler.  Moved the air-handler from the attic to the garage and re-designed and installed new duct work to accommodate the move.  Works great and no more worries about overflowing drain pan damaging the ceiling and wood floors.  Not to mention making it easier to maintain the AH unit.  The guys worked through the night to make sure the AC was back on before they left the job.   Thanks for a job well done.

Sunstate mechanical is truly the best contractors I have experienced since I moved into my house 30 years ago.  I have been dealing with Joe and his crew for over 11 years now. They are a trustworthy, respectful, experienced crew who works with you and gives you a fair value.  They just completed a big job replacing my A/C, gas furnance and condenser.  They did an excellent job, no short cuts, made sure everything was functional, and cleaned up the area nicely before they left.

Sunstate Mechanical are absolutely one of the best.  I have had two new units installed from them, and the work they did was spectacular.  The crew was prompt (even called ahead to confirm the appointment), incredibly professional, and they left the area around the air handler somehow cleaner than when they arrived.  I have had no issues with my units over the years because Sunstate Mechanical took the time to do it right the first time.
