    Frequently Asked Questions about AC Replacement

    Find answers to common questions about replacing your air conditioner. Get informed and make the best decision for your home or business.

    How can I make my air conditioner more energy efficient?

    Here are some ways to make your air conditioner more energy-efficient::
    • Regular Maintenance: Clean or replace your air filters every 1-3 months and keep the area around your outdoor unit free of debris.
    • Upgrade to a High-SEER Unit: If your AC is old, consider replacing it with an Energy Star certified unit with a high SEER rating.
    • Programmable Thermostat: Use a programmable or smart thermostat to optimize temperature settings and reduce energy consumption when you're away or asleep.
    • Seal Air Leaks: Seal air leaks around windows, doors, and other openings to prevent cool air from escaping.
    • Improve Insulation: Add insulation where needed to reduce heat transfer and improve your home's energy efficiency.
    • Use Window Coverings: Close curtains or blinds during the day to block out sunlight and prevent heat gain.
    • Zone Your HVAC System: If you have rooms that are rarely used or require different temperatures, consider zoning your system to avoid wasting energy only the occupied spaces.

    How does HVAC zoning work?

    HVAC zoning creates multiple, independently controlled areas, each with its own thermostat. Rather than conditioning the whole building evenly, you can target specific rooms or areas based on occupancy. It can be added to your existing system or included as part of a new HVAC installation. Zoning improves comfort and energy efficiency.

    How do I calculate the right BTU for my AC unit?

    A BTU (British Thermal Unit) measures cooling capacity from a space. Choosing the right BTU rating is important for optimal performance and energy efficiency. The required BTUs depend on several factors, including:
    • Room size (square footage)
    • Climate
    • Insulation levels
    • Window size and type
    • Number of occupants
    It's recommended to have a professional HVAC technician perform a load calculation to determine the ideal BTU rating for your new AC unit.

    What is an Energy Star certified AC unit?

    An Energy Star certified air conditioner meets certain criteria set by the U.S. Environmental Protection Agency. Energy Star AC units use less energy than standard models, resulting in lower energy bills and a smaller carbon footprint. Look for the Energy Star label when shopping for a new AC unit.

    • Programmable Thermostat: Use a programmable or smart thermostat to optimize temperature settings and reduce energy consumption during unoccupied periods.
    • Seal Air Leaks: Seal air leaks around windows, doors, and other openings to prevent cool air from escaping.
    • Improve Insulation: Add insulation to your attic, walls, and floors to reduce heat transfer and improve your home's energy efficiency.
    • Use Window Coverings: Close curtains or blinds during the day to block out sunlight and prevent heat gain.

    How does HVAC zoning work?

    HVAC zoning creates multiple, independently controlled areas, each with its own temperature control. Rather than conditioning the whole building evenly, you can target specific rooms or areas based on occupancy. A zoning system typically involves installing dampers in the ductwork that open and close to regulate airflow to different zones. Zoning is particularly beneficial for larger homes or buildings with uneven heating and cooling.

    A BTU (British Thermal Unit) measures cooling capacity from a space. Choosing the right BTU rating is important for optimal performance and energy efficiency. A qualified HVAC technician will calculate the necessary BTUs for your space based on factors like:
    • Room size (square footage)
    • Climate
    • Insulation levels
    • Window size and type
    • Number of occupants
    An accurate load calculation ensures you don't buy an undersized or oversized unit.

    What is an Energy Star certified AC unit?

    An Energy Star certified air conditioner meets strict energy efficiency guidelines set by the EPA. Energy Star AC units use less energy than standard models, resulting in lower energy bills and a smaller carbon footprint. Look for the Energy Star label when shopping for a new AC unit.
