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.

What are the signs that my AC unit is leaking refrigerant?

If your AC unit is leaking refrigerant, you might experience the following signs:
  • Warm air blowing from vents: If your AC is blowing warm air, even when set to a cool temperature, it's possible that the system is low on refrigerant.
  • Ice formation on refrigerant lines or evaporator coil: Refrigerant leaks can cause a drop in pressure and temperature, leading to ice buildup on the refrigerant lines or evaporator coil.
  • Hissing or bubbling sounds: A refrigerant leak may produce gurgling sounds coming from the AC unit.
  • Increased energy bills: A system with low refrigerant has to work harder to cool your home, resulting in higher energy consumption and costs.
If you suspect a refrigerant leak, it's essential to contact a qualified HVAC technician. Refrigerant is a controlled substance and requires special equipment and procedures for proper handling.

How do I prepare for an AC replacement installation?

Before the AC installation crew arrives, take the following steps:
  • Clear the Area: Remove any obstacles around the indoor and outdoor units, such as furniture, plants, or debris.
  • Protect Your Belongings: Cover furniture and floors near the installation area to protect them from dust or debris.
  • Provide Access: Make sure the installers have unobstructed access to your home's electrical panel, attic, or crawl space.
  • Trim Plants: Trim any plants or bushes near the outdoor unit to provide adequate airflow.
  • Communicate: Discuss the installation process with your contractor and address any questions or concerns.
Preparing appropriately will make the installation easier for the contractors.

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.

What is a SEER rating?

SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an air conditioner cools your home. The higher the SEER rating, the more energy-efficient the unit and the lower your cooling costs will be. The minimum SEER rating is typically 14, but more efficient units can have SEER ratings of 20 or higher. Though high-efficiency models may have a higher purchase price, they significantly reduce energy usage.

What are the signs that my AC unit is leaking refrigerant?

If your AC unit is leaking refrigerant, you might experience the following signs:
  • Warm air blowing from vents: If your AC is blowing warm air, even when set to a cool temperature, it's possible that the system is low on refrigerant.
  • Ice formation on refrigerant lines or evaporator coil: Refrigerant leaks can cause a drop in pressure and temperature, leading to ice buildup on the refrigerant lines or evaporator coil.
  • Hissing or bubbling sounds: A refrigerant leak may produce gurgling sounds coming from the AC unit.
  • Increased energy bills: A system with low refrigerant has to work harder to cool your home, resulting in higher energy consumption and costs.
Do not attempt to fix a refrigerant leak yourself. Refrigerant is a specialized substance that should only be handled by certified professionals

How do I prepare for an AC replacement installation?

Before the AC installation crew arrives, take the following steps:
  • Clear the Area: Remove any obstacles around the indoor and outdoor units, such as furniture, plants, or debris.
  • Protect Your Belongings: Cover furniture and floors near the installation area to protect them from dust or debris.
  • Provide Access: Make sure the installers have unobstructed access to your home's electrical panel, attic, or crawl space.
  • Trim Plants: Trim any plants or bushes near the outdoor unit that might restrict access.
  • Communicate: Discuss the installation process with your contractor and confirm timing and other arrangements.
Preparing appropriately will ensure a smooth and efficient AC installation process for the contractors.

How does HVAC zoning work?

HVAC zoning divides your home or building into separate zones, each with its own temperature control. This allows you to customize the temperature in different areas, improving comfort and saving energy. 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.

What is a SEER rating?

SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an air conditioner cools your home. The higher the SEER rating, the more energy-efficient the unit and the lower your cooling costs will be. The minimum SEER rating is typically 14, but high-efficiency models can have SEER ratings of 20 or higher. Though high-efficiency models may have a higher purchase price, they significantly reduce energy usage.
