how long should an ac unit last

Recently, we had a customer who filled out our Ask an Expert form and asked, “Once the [air conditioning] system is filled with Freon, how long might the Freon last? Forever so long as there are no more leaks? For context, this customer’s parents had a slow refrigerant leak in their AC system. These are great questions. So we wanted to share the answers with everyone. Freon (which is really just a particular brand of refrigerant) lasts forever. It’s not like gas in car; it does not get “used up.” You see, your air conditioner’s refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way. Of course, if you are low on refrigerant your system has a leak. So adding refrigerant without addressing the leak wastes money. A ton of it. R-22 refrigerant (a common refrigerant in older ACs) is expensive because it’s being phased out by the EPA. Adding 7 lbs of Freon could easily cost you $700. So, that leads to the next question.
Age eventually takes its toll on an air conditioner, so you could say a refrigerant leak is inevitable. Refrigerant circulates under high pressure and therefore wears down and thins the inside of the tubing. A better question is, “What can I do to prevent refrigerant leaks?” Your goal is to prevent refrigerant leaks and, when you do get them, nip them in the bud before they get too large. The larger the leak, the more refrigerant you lose. Keep your dog away from the outside AC unit Dog urine is acidic and can eat through the refrigerant coils. So keep your pooch away. Alternately, you could add a small fence around the unit. But make sure you leave at least 2 feet of space free around the AC so it can cool your home properly. Get professional AC maintenance once a year Many leaks occur because of vibration and wear and tear at multiple joints in the system. Annual air conditioner maintenance can catch any possible leak problems before they become expensive disasters.

Or when those old cabinets just can't be saved? The National Association of Home Builders' "Study of Life Expectancy of Home Components" gives a decent guesttimate by compiling life-cycle data from scores of product manufacturers and testing labs.
Following is a summary to guide you in planning your next big home improvement. The life expectancy of a typical appliance depends to a great extent on the use it receives. Moreover, appliances are often replaced long before they are worn out because changes in styling, technology and consumer preferences make newer products more desirable. Of the major appliances in a home, gas ranges have the longest life expectancy: 15 years. Dryers and refrigerators last about 13 years. Some of the appliances with the shortest lifespan are: compactors (6 years), dishwashers (9 years) and microwave ovens (9 years). Kitchen cabinets are expected to last up to 50 years, medicine cabinets for 20+ years, and garage/laundry cabinets for 100+ years. Closet shelves are expected to last for a lifetime. Masonry is one of the most durable components of a home. Chimneys, fireplaces, and brick veneers can last a lifetime, and brick walls have an average life expectancy of more than 100 years.
Natural stone countertops, which are less expensive than a few years ago, are gaining in popularity and are expected to last a lifetime. Cultured marble countertops have a life expectancy of about 20 years. Because they are subject to a wide range of conditions in different climates, the life expectancy of wooden decks can vary significantly. Under ideal conditions, they have a life expectancy of about 20 years. Exterior fiberglass, steel and wood doors will last as long as the house exists, while vinyl and screen doors have a life expectancy of 20 and 40 years, respectively. Closet doors are expected to last a lifetime, and French doors have an average life of 30 to 50 years. Copper plated wiring, copper clad aluminum, and bare copper wiring are expected to last a lifetime, whereas electrical accessories and lighting controls are expected to last 10+ years. Kitchen sinks made of modified acrylic will last 50 years, while kitchen faucets will work properly for about 15 years.
The average life of bathroom shower enclosures is 50 years. Showerheads last a lifetime, while shower doors will last about 20 years. Bath cabinets and toilets have an unlimited lifespan, but the components inside the toilet tank do require some maintenance. Whirlpool tubs will function properly for 20 to 50 years, depending on use. All natural wood floorings have a life expectancy of 100 years or more. Marble, slate, and granite are also expected to last for about 100 years, but can last less due to a lack of maintenance. Vinyl floors last up to 50 years, linoleum about 25 years, and carpet between 8 and 10 years (with appropriate maintenance and normal traffic). Poured as well as concrete block footings and foundations last a lifetime, assuming they were properly built. Termite proofing of foundations will last about 12 years if the chemical barriers put in place during construction are left intact. Waterproofing with bituminous coating lasts 10 years, but if it cracks it is immediately damaged.
Concrete or cast iron waste pipes are expected to last 100 years or more. Framing and Other Structural Systems Framing and structural systems have extended longevities: poured-concrete systems, timber frame houses and structural insulated panels will all last a lifetime. Wall panels and roof and floor trusses will similarly last a lifetime. Softwood, hardboard, and plywood last an average of 30 years, while OSB and particleboard are expected to function properly for 60 years. Garage door openers are expected to last 10 to 15 years, and light inserts for 20 years. Home technology systems have various life expectancies. While a built-in audio system will last 20 years, security systems and heat/smoke detectors have life expectancies of 5 to 10 years. Wireless home networks and home automation systems are expected to work properly for more than 50 years. Heating, Ventilation, and Air Conditioning (HVAC) Heating, ventilation, and air conditioning systems require proper and regular maintenance in order to work efficiently, but even in the best case scenarios most components of such systems only last 15 to 25 years.
Furnaces on average last 15-20 years, heat pumps 16 years, and air conditioning units 10-15 years. Tankless water heaters last more than 20 years, while an electric or gas water heater has a life expectancy of about 10 years. Thermostats usually are replaced before the end of their 35-year lifespan due to technological improvements. Insulation and Infiltration Barriers As long as they are not punctured, cut, or burned and are kept dry and away from UV rays, the cellulose, fiberglass, and foam used in insulation materials will last a lifetime. This is true whether the insulation was applied as loose fill, house wrap, or batts/rolls. Ladders are expected to last a lifetime, and life expectancy of lifts is about 8 to 10 years. Custom millwork will last a lifetime, and all stairs—circular and spiral stairs, prebuilt stairs and attic stairs—are expected to last a lifetime. Paint, Caulks and Adhesives Both interior and exterior points can last for 15 years or longer, however home owners often paint more frequently.
Hardboard panels and softwood panels are expected to last 30 years, while oriented strand board and particleboard have a life expectancy of 25-30 years. Wall panels are expected to last a lifetime. The life of a roof depends on local weather conditions, proper building and design, material quality, and adequate maintenance. Slate, copper, and clay/concrete roofs have the longest life expectancy—over 50 years. Roofs made of asphalt shingles last for about 20 years while roofs made of fiber cement shingles have a life expectancy of about 25 years, and roofs made of wood shakes can be expected to last for about 30 years. Outside materials typically last a lifetime. Brick, vinyl, engineered wood, stone (both natural and manufactured), and fiber cement will last as long the house exists. Exterior wood shutters are expected to last 20 years, depending on weather conditions. Gutters have a life expectancy of more than 50 years if made of copper and for 20 years if made of aluminum.
