How long does air conditioner installation take?

Most standard AC installations are completed in one day. The timeline varies based on the system type, whether new ductwork or electrical work is required, and the overall complexity of your home’s setup. A straightforward central AC replacement typically takes four to eight hours, while more involved installations can take longer. If your installation requires new electrical work, your service professional will coordinate that in advance. Clearing the area around your existing equipment before your appointment also helps keep things moving smoothly. Your local Aire Serv service professional will provide a realistic timeframe during your initial assessment, so you know exactly what to expect on installation day.

How do I know what size AC unit I need?

Proper sizing is one of the most important parts of AC installation, and it takes more than just square footage to get it right. An oversized system short-cycles, meaning it turns on and off too frequently, which wastes energy and puts unnecessary wear on the equipment. An undersized unit runs constantly and still struggles to keep up on the hottest days. Our service professionals perform a Manual J load calculation that accounts for your home’s square footage, insulation, windows, and local climate to recommend the right cooling capacity for your home before any equipment is selected. Aire Serv will match you with the right-sized system for your home and budget. Contact your local Aire Serv to schedule a sizing assessment and get a recommendation built around your specific home.

How often should I replace my air conditioner?

Most air conditioners last 10 to 15 years with regular maintenance. If your system is approaching or past that range and experiencing recurring issues, AC replacement is usually the more cost-effective choice. Age is not the only factor. Rising energy bills, frequent repairs, uneven cooling, or refrigerant issues can all signal that your system is no longer running efficiently, even if it has not yet reached the 15- year mark. As a general rule of thumb, if a major repair costs close to half the price of a new system, replacement may be the better long-term choice. Comparing your current system’s efficiency rating to newer high-efficiency models may help reduce long-term energy use and operating costs. Your Aire Serv service professional can help you weigh the options and plan your air conditioner replacement with confidence. Schedule an assessment to get an honest recommendation based on your system and home.

Professional AC Installation Services

A properly installed air conditioner is about more than comfort. It’s about efficiency, reliability, and long-term savings. Our Home Comfort Designers assess your home’s size, layout, and existing ductwork to recommend the right system and install it to manufacturer specifications. From load calculations to final testing, we handle every step so you can enjoy cool, consistent comfort from day one.

If your air conditioner is more than 10 to 15 years old, requires frequent repairs, or struggles to keep up on hot days, air conditioner replacement is likely the smarter investment. A new, high-efficiency system can help reduce your monthly energy bills while improving indoor comfort and air quality. Aire Serv will evaluate your current system and help find the right AC replacement for your home and budget.
Watch for warning signs like rising energy bills, uneven cooling, unusual noises, or warm air coming from your vents. These symptoms often mean your system is working harder than it should. Catching problems early can be the difference between a minor repair and a full AC replacement. Our service professionals provide honest assessments and upfront pricing so you know what to expect before work begins.
