Frequently Asked Questions about AC Replacement

Considering a new AC unit? Learn more about AC replacement. Get informed and make the best decision for your home or business.

How often should I replace my AC filter?

Changing your AC filter is essential for maintaining a healthy home environment and ensuring the peak performance of your AC. Generally, it's recommended to replace your AC filter every 1-3 months. However, several factors can influence how often you should change your filter, including:
  • Pets
  • Allergies
  • High dust levels in your home
  • Frequent use of the AC system
Check your filter monthly and replace it more often if it appears dirty or clogged.

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

A heat pump is an HVAC system that can both heat and cool. It works by transferring heat between the inside and outside 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, effectively moving heat from outdoors to indoors to heat your space. A heat pump could reduce your utility bills while providing year-round comfort.

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

If your AC unit is leaking refrigerant, you may notice the following signs:
  • Warm air blowing from vents: If your AC is blowing warm air, even when set to a cool temperature, it could indicate 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 hissing or bubbling 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 controlled substance that should only be handled by certified professionals

What type of AC unit is best?

The best type of AC unit for you depends on factors like your budget, the size of your home, and your desired energy efficiency. Common types include:
  • Central Air Conditioners: These systems cool the entire home using a system of ductwork.
  • Ductless Mini-Splits: These provide customized comfort by cooling individual rooms or zones.
  • Window Air Conditioners: An affordable option for cooling a single room.
  • Portable Air Conditioners: Portable units can be moved easily from room to room.
  • Heat Pumps: These systems extract heat from the air to provide both heating and cooling.
Consult with a qualified HVAC technician to determine the best type of AC for your home or business.

What type of AC unit is best?

The ideal type of AC unit for you depends on your specific needs and preferences. Consider the following types of units:
  • Central Air Conditioners: The most common type for whole-home cooling.
  • Ductless Mini-Splits: Ideal for homes without ductwork, offering zoned cooling.
  • Window Air Conditioners: These units are installed in a window opening.
  • Portable Air Conditioners: Offer flexible cooling for rooms where a window unit is not practical.
  • Heat Pumps: These systems extract heat from the air to provide both heating and cooling.
