FAQs

O'Ryan's Heating and Cooling

  • How often should I change my filters?

    We advise replacing standard filters every three months to ensure your system operates at peak efficiency and maintains good air quality.
  • Why is my HVAC not blowing cold?

    Begin by checking your filters and confirming all power switches are in the 'on' position. If the problem continues, we recommend contacting our service team for additional troubleshooting.
  • Why is my coil freezing?

    Coil freezing typically occurs due to blocked filters or low refrigerant levels. If you're encountering this issue, we suggest booking a diagnostic appointment with one of our certified technicians.
  • What is the average lifespan of an HVAC system?

    HVAC systems generally last between 8 to 12 years. However, in coastal regions, the system's lifespan may be reduced due to environmental conditions.
  • How often should I have my HVAC system serviced?

    For home systems, we recommend servicing twice a year. Commercial HVAC systems should undergo maintenance every three months to maintain optimal performance.
  • What size HVAC system do I need for my home?

    While a manual J load calculation provides the most accurate sizing, a general guideline is one ton of cooling capacity per 500 square feet of living area. For precise sizing, we recommend scheduling a professional assessment.
  • What is the difference between a heat pump and a furnace?

    A heat pump uses the outdoor condensing unit to generate heat, whereas a furnace only distributes air without producing heat. Installing both a heat pump and furnace can provide energy-efficient heating, with the furnace acting as a backup during extremely cold periods.
