A New Cooling System That Actually Keeps Up
Most comfort complaints about a new air conditioner trace back to sizing and installation, not the brand on the box. Aerex Mechanical runs a load calculation on your home, matches the indoor and outdoor equipment properly and installs it to the manufacturer's specifications, with permits and inspection included.
We install central air conditioners, heat pumps and ductless mini-split systems. The proposal lays out your options with efficiency ratings and real operating cost differences, so you can choose based on numbers rather than a sales pitch.
- Load calculation for correct sizing
- Central AC, heat pump and mini-split systems

Residential AC Installation FAQs
What Arlington homeowners ask before replacing an air conditioner.
It depends on more than square footage. Insulation, window area, orientation, ceiling height and duct condition all change the answer. We run a load calculation on every installation so the system is neither oversized nor undersized.
A typical replacement is finished in a single day. Installations that include new ductwork, electrical upgrades or a mini-split with several indoor heads may take longer, and the proposal will say so.
If the furnace or air handler is also aging, replacing both ensures matched equipment and usually costs less than two separate jobs. If it is in good shape and compatible, we can replace the air conditioner alone.
Yes. We pull the permit, schedule the inspection and are present for it. Permitted work keeps the manufacturer warranty valid.
