How much does it cost to install AC in Washington?
Rough range for central AC is $3,500 to $7,500 — size, efficiency rating, and ductwork condition move that number. Mini-splits run $2,000 to $5,000 per zone. Book the free estimate and we give you a real number, not a range pulled from a calculator.
Is a 7 year old AC unit old?
Not really. Seven years in, a well-maintained unit has plenty of life left. Most central AC systems run 12 to 15 years. At 7, repair is almost always the right call — unless something major failed on a system that hasn’t seen a tune-up in years.
What is considered an old AC?
Past 12 to 15 years, the math starts shifting. Efficiency is down, parts take longer to source, and repair costs creep up relative to what a replacement would run. A 14-year-old unit that’s been serviced every year might still have time — we look at each one before saying either way.
How to know if AC is new or old?
Look at the manufacturer label on the outdoor unit — production date is usually right there. Serial numbers on most brands also encode the build year. No label, no problem — a technician can pull the age from the model number and refrigerant type.
Can an AC last 40 years?
The full system, no. Compressors, coils, and refrigerant circuits don’t hold up that long even with perfect maintenance. Some components outlast the rest, but the system as a whole typically doesn’t make it past 20 years. Air conditioning installation Spokane, WA calls we get often involve units that outlasted their rated lifespan — but were costing way more to run than a replacement would.
How to tell if AC is going bad?
Warm air when the system’s running. Weak airflow. Ice on the outdoor unit. Noises that weren’t there before — grinding, rattling, squealing. Short cycling. Bills climbing without any change in usage. One of those might be a minor issue. Several together means the system is working too hard to keep up.
How many years should AC be replaced?
12 to 15 years is the general benchmark. Systems that get annual maintenance tend to reach the top of that range. Systems that don’t, rarely do. When repairs start stacking up or efficiency has dropped noticeably — that’s the signal, not a specific birthday.
