Air Conditioning Installation in Boise

Looking to install a new air conditioning system in your Boise home? Whether you’re building new or replacing an aging unit, proper air conditioning installation is one of the most important decisions you’ll make for your home’s comfort. For over 70 years, Owyhee Heating, Air Conditioning & Plumbing has been the trusted name for air conditioning installation throughout the Nampa and Boise area of Idaho.

We understand that air conditioning installation involves more than just placing equipment in your home. From the initial sizing of your system to the final thermostat setup, every detail matters. Our installation experts approach each project with precision and care, ensuring your new system operates at peak efficiency from day one.

Why Professional Sizing Matters

One of the most critical aspects of air conditioning installation is selecting the right system size for your home. Using calculations and a thorough assessment of your space, our experts determine precisely what capacity your home needs. This includes proper sizing of your ductwork and calculating how much conditioned air each room requires to maintain comfortable temperatures throughout your home.

The Air Conditioning Installation Process

Understanding what’s involved in your installation helps set proper expectations. Depending on whether you’re building new or replacing an existing system, the scope of work may vary, but typically includes the following main components:

  • Outdoor unit installation
  • Copper line set installation
  • Indoor unit placement
  • Evaporator coil pairing with furnace systems
  • Thermostat and wiring installation
  • Electrical power connections
  • Condensation drain system
  • Duct system preparation or upgrades

For new home construction, our installation team plans, designs, and executes each step with precision. For replacement installations in existing homes, we assess what infrastructure remains in good condition and what needs upgrading or replacement.

Refrigerant Considerations for Older Systems

If your home has an air conditioning system over ten years old, it likely uses R22 refrigerant, which was phased out in 2010 and replaced by the more environmentally friendly R410A. Since no new equipment is manufactured with R22, replacing an older unit often means you’ll also need to replace your indoor coil or entire indoor unit to maintain system compatibility and efficiency.

Frequently Asked Questions about Air Conditioning Installation in Boise, ID

Our experts use detailed calculations and assessment of your home’s square footage, layout, insulation, and sun exposure to determine the precise system capacity your home requires. Proper sizing is critical. An oversized unit cycles on and off too frequently, while an undersized unit won’t adequately cool your home. We also size your ductwork to ensure proper air distribution to each room.
In many cases, existing ductwork can be reused if it’s in good condition and properly sized for your new system. However, during the installation process, our team assesses your ductwork to ensure it will work effectively with your new unit. If it’s damaged, leaking, or improperly sized, we’ll recommend upgrades to maximize efficiency and comfort.
R22 was phased out in 2010 and replaced by the more environmentally friendly R410A. Since manufacturers no longer produce equipment using R22, replacing an older unit that uses this refrigerant often means you’ll also need to replace your indoor coil or entire indoor unit to ensure compatibility and proper operation with modern refrigerants.
Installation timelines vary depending on your situation. New home installations typically require more time since our team must plan, design, and execute each component from the ground up. Replacement installations in existing homes may be faster if much of the infrastructure is already in place and in good condition. Our team will provide a timeline estimate based on your specific project.
A complete installation includes the outdoor unit, copper refrigerant lines, indoor unit, evaporator coil if paired with a gas furnace, thermostat and wiring, electrical power connections, a condensation drain system, and duct system preparation or installation. We’ll assess your home to determine which components you need and ensure everything is properly sized and installed for optimal performance.
