Frequently Asked Questions About HVAC

A central air conditioner comes in two main types: split systems and packaged units. Both are designed to cool your entire home efficiently.

In a split system, the condenser and compressor are outside, while the evaporator is indoors. A packaged unit combines all components in one outdoor cabinet, often placed on a roof or concrete slab.

The system draws indoor air through return ducts, filters it, cools it via the evaporator coil, and then circulates it back through supply ducts. This cycle ensures consistent, filtered cool air.

We recommend checking your filters every 3 months and replacing them as needed. Dirty filters reduce air quality and strain your system.

Annual maintenance is recommended to ensure optimal performance and extend the life of your unit, which typically lasts 15–25 years.

Sizing depends on the layout and square footage of your home. We offer free consultations to help determine the right system for your needs.

SEER stands for Seasonal Energy Efficiency Ratio. It measures cooling efficiency — the higher the SEER, the more efficient your air conditioner.

We recommend the “Auto” setting. This ensures the fan runs only during heating or cooling cycles, saving energy and reducing wear.
