There are several indicators that a replacement makes more sense than another repair. If your system is 10–15 years old, requiring frequent repairs, struggling to keep up with Boise’s summer heat, or driving up your energy bills despite regular maintenance, it’s likely time to start thinking about a new unit. Other telling signs include refrigerant that needs constant recharging, inconsistent cooling throughout your home, or a repair estimate that exceeds half the cost of a new system. We can assess your current equipment honestly and help you weigh the cost of repair against the long-term benefits of a new, high-efficiency installation—so you can make the decision that’s right for your home and budget.

Most standard residential AC installations in the Treasure Valley are completed in a single day. A straightforward replacement of an existing system typically takes anywhere from four to eight hours depending on the equipment, accessibility, and any additional work needed such as electrical updates or refrigerant line adjustments. More complex installations, such as first-time central air in a home without existing ductwork, or a multi-zone ductless mini-split system—may take longer. When you schedule with Comfort Systems Heating & Air Conditioning, we’ll give you a clear timeframe upfront so you can plan accordingly and minimize disruption to your household.

Proper sizing is one of the most important factors in a successful AC installation, and it’s not simply a matter of square footage. Comfort Systems Heating & Air Conditioning performs a thorough assessment of your home before making any recommendations, taking into account your floor plan, ceiling height, insulation levels, window placement, sun exposure, and the specific demands of Boise’s hot, dry climate.
This process—known as a load calculation—ensures the system we install is neither too large nor too small. An oversized unit will short cycle and leave your home feeling uneven, while an undersized one will run constantly without keeping up. Getting the sizing right from the start means better comfort, lower energy bills, and a longer system lifespan.
