On average a system can last between 10 to 25 years with preventative maintenance. The life expectancy of any HVAC system or equipment depends on the preventative maintenance and service performed on them, as well as the type of equipment and your usage. You want to always have a qualified HVAC technician perform maintenance at least twice a year on your equipment.
The life expectancy of a furnace depends on several factors. If your furnace was correctly sized for your square footage and installed by a licensed technician, you can expect a long lifespan. With regularly scheduled maintenance, your furnace could last anywhere from 15 years up to 25 years.
Just like with a furnace, an air conditioning unit’s lifespan will vary depending on how well it was sized for your home and if it was installed properly. You can get between 12 to 15 years out of your air conditioner if you have it inspected and serviced at least twice a year. Maintenance will catch issues with your air conditioner before they turn into massive failures down the road.
Heat pumps generally last up to 16 years with proper maintenance. A heat pump does the jobs of a furnace and air conditioner, so it doesn’t ever get a break. There can be extensive problems that lead to mechanical breakdowns and failures if you don’t have a technician inspect and clean the unit regularly.
The life expectancy of a tankless water heater is dependent on the water quality, environmental conditions, usage rates, and scheduled maintenance performed on the unit. On average you can expect your tankless water heater to last up to 20 years or longer.
Often times, a water heater is forgotten when it comes to routine maintenance, but when the water turns cold, people soon remember them. Regular inspections and maintenance will keep your electric or gas water heater performing up to 10 years.
Thermostats can last up to 25 years, but most people replace them as technology changes. Preventative maintenance inspects your thermostat for any performance issues, and a technician will let you know if your thermostat is lacking. Considering the importance of your thermostat for your heating and cooling system’s performance, you want to make sure it remains operational at all times.
