3.5 ton - best for spaces between 1700- 2100 sq ft depending on your home's insulation and your climate
SEER2 rating helps consumers compare energy efficiency when choosing a new air conditioner. Higher SEER2 ratings mean significant utility savings. The federal minimum is 14 SEER2 with ratings into the 20 SEER2 range. A 20 SEER2 uses half the energy of a 10 seer much like MPG ratings for vehicles.
Best if you already have a self-contained outdoor unit in place now or if you have no place for an indoor unit (air handler/furnace)
Best for cold climates and if you already have a gas furnace or a gas fuel supply already available.
You'll need about 25-30 Btu's per sq. foot for warmer winter climates and about 35-50 Btu's per sq. foot for colder winter climates - highly dependent on construction type and insulation values.

ACDirect does not yet provide installation services directly. However, most of our customers successfully arrange installation through local licensed HVAC contractors. These systems are designed for professional installation and typically include the components your installer will need.
Here’s how it works:
Hire a licensed HVAC technician in your area
Use platforms like Angi, Thumbtack, or a local HVAC directory to find reliable professionals
Confirm your installer is experienced with the system type you’re purchasing
Note:
Please be aware if you choose to install HVAC equipment yourself and don’t possess proper HVAC licensing, you will void the manufacturer’s factory warranty. If you are capable of a factory-compliant installation yourself, you will need a licensed HVAC contractor to sign off on your work, fully confirming factory-compliant workmanship.
