Frequently Asked Questions about AC Replacement

What are the signs of a refrigerant leak?

If you suspect a refrigerant leak in your air conditioner, look for these signs:

Warm air coming from the vents:
Ice on the evaporator coil or refrigerant lines:
Hissing or bubbling sounds from the AC unit:
Increased energy bills:
Sweet or oily odor near the AC unit:

If you notice any of these signs, it’s important to have your system inspected. Refrigerant leaks can be harmful to the environment and should be addressed promptly. Continuing to operate a leaking AC unit can also damage the compressor, leading to even more expensive repairs.

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 a heat pump, and how does it work?

A heat pump is an HVAC system that provides heating and cooling. It extracts and moves heat between the inside and outside air. In cooling mode, 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. 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 do I know if I need a new AC unit?

Several signs indicate it's time to replace your air conditioner:

Age: If your AC unit is more than a decade old, it's probably less efficient.
Frequent Repairs: Constant repairs can be a sign of bigger problems to come.
High Energy Bills: Rising utility bills can indicate a problem with your cooling system.
Inconsistent Cooling: Uneven temperatures, or rooms that are hard to cool indicate a struggling AC unit.
Strange Noises: Unusual noises like clanging, hissing, or buzzing suggest component failure.
Refrigerant Leaks: Refrigerant leaks require professional repair and are a sign that the unit may be failing.

If you notice these signs, get a professional AC inspection.
