    Frequently Asked Questions

    How often should I schedule HVAC maintenance?

    We recommend scheduling maintenance at least twice a year — once before the heating season and once before the cooling season. Regular maintenance helps ensure your system is prepared for the demands of each season. Ask our heating and air conditioning contractors about a maintenance plan today!

    How long does an HVAC system typically last?

    With proper maintenance, an HVAC system can last between 15 to 20 years. Regular upkeep and timely repairs can help extend the lifespan of your unit.

    What is the best heating and air conditioning system for my home?

    The best system depends on various factors, including your home’s size, insulation, and specific heating and cooling needs. As a leading HVAC contractor in O’Fallon, MO, we can help you choose the most suitable system for your home.

    How can I improve my air conditioner’s energy efficiency?

    Scheduling regular maintenance, using programmable thermostats, sealing ducts, and upgrading to energy-efficient systems are some ways to enhance your home’s energy efficiency. Our HVAC company can provide additional recommendations based on your specific situation.

    Why is my air conditioner freezing up?

    Common causes of a frozen air conditioner include low refrigerant levels, restricted airflow, or a dirty evaporator coil. It’s important to have a professional HVAC contractor diagnose and address the issue to prevent further damage. Call our experts today!

    What is the difference between a single-stage and a two-stage furnace?

    A single-stage furnace operates at full capacity whenever it’s on, while a two-stage furnace can operate at both low and high capacities. Two-stage furnaces provide more consistent temperatures and improved energy efficiency. Our HVAC contractors can help you determine which model is best for your household.

    What is a heat pump, and how does it differ from a traditional furnace?

    A heat pump is an HVAC system that can both heat and cool a home. Unlike a traditional furnace, which generates heat through combustion, a heat pump moves existing heat, making it more energy-efficient in moderate climates.

    Why is my furnace making a loud noise?

    Your furnace may be making obnoxious noises due to loose components, a malfunctioning blower motor, or a dirty burner. Do not attempt to tackle this problem on your own; instead, look for experienced HVAC companies like Stay Cool Climate Control. We will inspect and repair the system to prevent further damage and ensure safe operation.
