Late Summer AC Care: Keeping Your Clearwater Home Comfortable Through September 

September may signal the beginning of fall in many parts of the country, but Clearwater homeowners know that summer temperatures don't disappear just because the calendar changes. Your air conditioner may still have weeks of hard work ahead, especially after running throughout Florida's long, hot summer.


Late summer is a good time to give your cooling system some extra attention. A few simple steps can help your AC keep running efficiently, and catching problems early can help you avoid an unexpected breakdown when you still need dependable cooling.


Replace or Check Your Air Filter

One of the easiest ways to care for your air conditioner is to check its filter regularly. After months of frequent use, an AC filter can become clogged with dust, pet hair, and other airborne particles. A dirty filter restricts airflow through your HVAC system. This can make your air conditioner work harder to cool your home and may increase energy use or put unnecessary strain on the system.


Check your filter and replace it if it appears dirty. The appropriate replacement schedule can vary depending on your household, filter type, pets, and other factors, so follow the recommendations for your particular system and filter.


Keep the Outdoor Unit Clear

Your outdoor AC unit needs adequate airflow to release heat effectively. Grass clippings, leaves, weeds, and other debris can accumulate around the equipment during the summer. Take a look around the outdoor unit and carefully remove vegetation or loose debris that could obstruct airflow. Avoid placing objects against the equipment, and give the unit sufficient room to operate. While homeowners can handle basic cleanup around the unit, leave internal cleaning and repairs to an HVAC professional.


Pay Attention to Changes in AC Performance

After relying on your cooling system all summer, you probably have a good idea of how it normally operates. That makes September an excellent time to pay attention to anything that seems different.


Potential signs of an AC problem can include:

  • Unusual noises or odors
  • Weak airflow from the vents
  • Warm or insufficiently cool air
  • Frequent cycling
  • Difficulty maintaining the thermostat setting
  • Unexplained increases in cooling costs
  • Water or moisture around the indoor equipment


These changes don't necessarily tell you exactly what is wrong with the system. However, they can indicate that it's time to schedule professional AC repairs in Clearwater, FL, before a minor issue has an opportunity to become more serious.


Don't Ignore Florida's Humidity

Keeping your Clearwater home comfortable isn't only about lowering the temperature. Your air conditioner also helps remove moisture from indoor air as it cools your home. If your house suddenly feels unusually humid or clammy even when the AC is running, don't simply turn the thermostat lower. Excess indoor humidity can sometimes indicate that the cooling system isn't operating as it should. A professional HVAC technician can evaluate the system and determine whether an AC problem is affecting indoor comfort.


Give Your AC a Late-Summer Checkup

Months of heavy summer operation can take a toll on cooling equipment. Professional maintenance gives an HVAC technician a chance to inspect key system components and catch developing issues. During HVAC maintenance, technicians may perform tasks such as cleaning coils, clearing condensate drain lines, checking electrical connections, evaluating motor operation, and checking the system's refrigerant charge. Reliant Heating & Air Conditioning offers preventative maintenance services designed to help keep HVAC systems operating properly.


Even if your air conditioner seems to be working normally, preventive care can help prepare it for the remaining warm weather and give you a better idea of its overall condition after another Clearwater summer.


Know When It's Time to Call an HVAC Professional

Some AC care is simple enough to handle yourself, such as changing a filter or clearing debris away from the outdoor unit. Other problems require professional tools, training, and diagnosis.


If your system stops cooling properly, begins making unusual noises, repeatedly cycles on and off, or shows other signs of trouble, arranging professional service sooner can help prevent additional strain on the equipment.


Reliant Heating & Air Conditioning provides AC maintenance and repair services for Clearwater homeowners and services all makes and models.
