Air Conditioners

Air conditioners remove heat and humidity from indoor spaces to keep homes and commercial buildings comfortable during warm weather. At HVAC365, you’ll find residential and light commercial cooling systems designed for replacement projects, new construction, upgrades, and energy-efficient retrofits.

Whether you’re replacing an aging central AC system or planning a complete HVAC installation, choosing the right system size, efficiency level, and configuration matters for long-term comfort and operating costs.

What you’ll find here

  • Central air conditioner condensers and split systems
  • Packaged air conditioning units (all-in-one outdoor systems)
  • Ductless mini split air conditioners and inverter systems
  • Residential and light commercial cooling equipment
  • Systems commonly called AC units, central air, or straight cool systems

How to choose

  • Match system capacity (BTU/tonnage) to your home or building size
  • Compare SEER2 efficiency ratings for energy savings and rebate eligibility
  • Verify voltage and electrical requirements before installation
  • Confirm compatibility with existing air handlers, coils, or ductwork
  • Consider inverter or variable-speed technology for quieter, steadier comfort
  • Check refrigerant type when replacing older R-410A equipment
  • For commercial or multi-zone applications, review airflow and zoning needs

Split System vs Package Unit

  • Split systems: Indoor and outdoor components separated; common for homes with ductwork
  • Package units: All components housed in one outdoor cabinet; useful when indoor space is limited
  • Mini splits: Duct-free option ideal for additions, garages, offices, or room-by-room control

FAQ

How do I know what size air conditioner I need?
Proper sizing depends on square footage, insulation, climate, windows, and airflow—not just home size alone.

What does SEER2 mean?
SEER2 measures cooling efficiency. Higher ratings generally reduce energy usage and improve long-term operating costs.

Can I replace just the outdoor condenser?
Sometimes, but system matching is important for efficiency, refrigerant compatibility, and warranty compliance.

Are mini splits good for whole-home cooling?
Yes. Multi-zone mini split systems can cool multiple rooms without traditional ductwork.

Do air conditioners require professional installation?
Most central systems and mini splits should be installed by licensed HVAC professionals for proper performance and code compliance.

How often should AC systems be maintained?
Annual maintenance is recommended to protect efficiency, airflow, refrigerant performance, and equipment lifespan.
