  • What does HVAC stand for?

    HVAC is an acronym for heating, ventilation, and air conditioning. This term encompasses the systems responsible for regulating temperature, humidity, and air quality within residential and commercial spaces.
  • How often should I have my HVAC system serviced?

    We recommend scheduling professional maintenance biannually. Ideally, have your cooling system serviced in spring and your heating system in fall. This regular upkeep ensures optimal efficiency and helps prevent costly repairs down the line.
  • What's the average lifespan of an HVAC system?

    Typically, HVAC systems operate effectively for 10 to 15 years. Factors such as brand quality, installation precision, and maintenance frequency can influence longevity. With diligent care and regular servicing, some systems may exceed this average lifespan.
  • How can I tell if my HVAC system needs repair or replacement?

    Signs that your system may need repair or replacement include age exceeding 10 years, frequent repair needs, or inconsistent heating and cooling throughout your space. Our technicians can provide a thorough assessment and offer professional recommendations based on your system's condition.
  • What size HVAC system do I need?

    The appropriate HVAC system size depends on various factors including your property's square footage, insulation quality, window count, and local climate conditions. Our team conducts comprehensive on-site load calculations to determine the ideal system size for optimal comfort and efficiency in your space.
  • How can I improve my system's energy efficiency?

    To enhance your HVAC system's energy efficiency, we suggest regular filter replacements, keeping vents unobstructed, scheduling bi-annual maintenance, and considering upgrades such as a high-efficiency unit or programmable thermostat. These measures can contribute to reduced energy consumption and lower utility costs.
  • Why is my AC blowing warm air?

    Warm air from your AC could indicate several issues, including low refrigerant levels, a clogged air filter, thermostat malfunction, or compressor problems. Our skilled technicians can quickly diagnose and address the root cause to restore your system's cooling functionality.
  • How often should I change my air filters?

    For most residential settings, we advise changing air filters every 1 to 3 months. Households with pets or individuals with allergies may benefit from more frequent replacements to maintain optimal airflow and indoor air quality.
  • What temperature should I set my thermostat to in the summer?

    For a balance of comfort and energy efficiency during summer, we recommend setting your thermostat to 76-78°F when occupied and slightly higher when the space is vacant. Smart thermostats can automate these adjustments to optimize energy savings.
  • Why does my AC run constantly and never shut off?

    Continuous AC operation may indicate an undersized unit, a dirty condenser coil, or insufficient refrigerant levels. Our technicians can perform a thorough inspection of your system to identify and resolve the issue, ensuring efficient operation.
