Is a bigger AC unit better?

The size of your air conditioner should suit the size of your home and cooling needs. Installing a unit that’s too large or too small for your home will result in expensive energy bills and reduced comfort. You should always work with a licensed professional to help you determine which AC unit is right for your home and budget.

How long do AC units last?

They can last 15 to 20 years, but only if your AC system is professionally installed and regularly maintained by an experienced technician.

What does SEER mean?

SEER stands for seasonal energy efficiency ratio. The higher the number, the more efficient your AC is at cooling while using less energy. These ratings range from 13 to 21 on average. Our technicians can help you select the best system and SEER rating for your needs.
