Frequently Asked Questions about AC Replacement

Find answers to common questions about replacing your air conditioner. We'll help you find the perfect cooling solution.

How can I make my air conditioner more energy efficient?

Improve your energy efficiency by implementing these tips:
  • 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 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 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 not consistently occupied, consider zoning your system to avoid wasting energy specific areas.

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.

How long does it take to replace an AC unit?

A typical AC replacement takes approximately 4 to 8 hours for a standard installation. Factors that can influence installation time include:
  • The size and type of AC unit: Larger, more complex systems will naturally take more time to install.
  • The condition of existing ductwork (if applicable): If your home has existing ductwork, the contractor will need to inspect it and ensure it's compatible with the new AC unit before installing the new unit.
  • Accessibility: The ease with which installers can access your HVAC equipment will help streamline the installation process.
  • Electrical work: If any electrical upgrades are required, the installation process may be longer.
Your chosen contractor will be able to give you a better idea of the timeframe once they've inspected your home or business.

What is a heat pump, and how does it work?

A heat pump is an HVAC system that provides heating and cooling. It works by transferring heat between the indoor and outdoor air. In the summer, the heat pump works like an AC unit, just like a traditional air conditioner. In the winter, it reverses this process, absorbing heat from the outside air (even in cold temperatures) and transferring it inside to warm your home. Heat pumps are highly efficient for both heating and cooling, making them a good alternative to traditional furnaces and air conditioners, especially in mild to moderate climates.

How can I make my air conditioner more energy efficient?

Here are some ways to make your air conditioner more energy-efficient::
  • Regular Maintenance: Schedule yearly or twice-yearly maintenance checkups to ensure your unit is clean and running efficiently.
  • 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 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.
  • Zone Your HVAC System: If you have rooms that are not consistently occupied, consider zoning your system to efficiently cool only the occupied spaces.

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

A BTU (British Thermal Unit) measures how much heat an air conditioner can remove from a space. Correct BTU calculations are crucial for properly sizing an AC unit. 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
It's recommended to have a professional HVAC technician perform a load calculation to determine the ideal BTU rating for your new AC unit.

How long does it take to replace an AC unit?

A typical AC replacement takes anywhere from a few hours to a full day, depending on the complexity of the installation.. Factors that might affect installation time include:
  • The size and type of AC unit: Larger, more complex systems will naturally require a longer installation.
  • The condition of existing ductwork (if applicable): If your home has existing ductwork, the contractor will need to inspect it and make any necessary repairs or modifications before installing the new unit.
  • Accessibility: Easy access to your existing unit and the installation location will help speed up the job.
  • Electrical work: If any electrical upgrades are required, the timeline may be longer.
Your chosen contractor will be able to give you a better idea of the timeframe once they've inspected your home or business.

What is a heat pump, and how does it work?

A heat pump is an air conditioner that provides heating and cooling. It extracts and moves heat between the indoor and outdoor air. In cooling mode, the heat pump extracts heat from inside your home and releases it outside, just like a traditional air conditioner. In heating mode, it reverses this process, effectively moving heat from outdoors to indoors to heat your space. A heat pump could reduce your utility bills while providing year-round comfort.
