The Importance of Regular Air Conditioning Service

Regularly scheduled air conditioning service is essential for preserving the longevity and efficiency of your HVAC system. If neglected, the equipment may not perform at its optimal level, leading to higher energy bills and potential breakdowns. Additionally, a poorly maintained system can compromise the quality of indoor air, causing a variety of health-related issues.

When an HVAC unit has gone without regular maintenance, dirt and dust particles accumulate on coils or filters, reducing airflow throughout the system and causing it to become overworked in order to reach desired temperatures - resulting in wasted energy and money. Scheduling regular maintenance helps keep these components clean by removing any built-up residue that could impede its performance over time.

Moreover, properly caring for your air conditioning system can help prevent expensive repairs due to worn out parts or debris buildup within the unit. On top of saving money on energy bills, regular upkeep assists in creating a healthier environment indoors by preventing contaminants from circulating through the air you breathe. To ensure your HVAC unit is always running optimally, schedule an AC service appointment with One Hour Heating & Air Conditioning of South Bay at least once a year.

Don't settle for anything less than the best. Choose One Hour Heating & Air Conditioning of South Bay for exceptional HVAC home service. Give us a call today at (424) 699-4628.

  • How often do I need to change my HVAC filter?

    Your filter should be changed every one to three months, depending on conditions in your home and your region’s climate.
  • Do you offer purchase financing?

  • What are the advantages of a smart thermostat?

  • What is HVAC?

    HVAC means Heating, Ventilation, and Air Conditioning. HVAC systems refer to air conditioners, furnaces, and any unit that cools indoor spaces during the summer and warm them in the winter.

    In general, an HVAC system takes in air, heats or cools that air, and blows it into a room or any indoor space. While many homes have separate air conditioning and heating units, others have a heat pump that cools and heats the house.

    Not only do HVAC systems maintain desired temperatures, but they also improve indoor air quality and regulate humidity levels. But most importantly, these units provide comfort all year round.

  • What is a SEER Rating?

    The SEER (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER rating, the more efficiently a unit operates. The SEER rating of any given unit can range anywhere from 13 to 21.
