Do You Know the Lifespan of Your HVAC Appliances?

hvac-lifespan-lengtheningHVAC equipments such as air conditioners, furnaces, washing machines, and dryers have different lifespans. Bearing in mind that they are also costly to replace, it really helps if you know the length of time they are meant to serve you so that you do not mistakenly replace units that still have life in them. Also, knowing the duration of service will give you the impetus to do everything in your power to maximize their lifespan.

Central Air Conditioning Units

These are common in homes and they come in different brands and models. Air conditioning units are made to last anything between 10 and 15 years. However, this is dependent on a number of things including their proper sizing and regular maintenance. When it comes to AC systems, bigger is not necessarily better. For your AC system to serve you for this period of time, it must be properly sized with your home cooling needs.

Oversize AC units tend to cycle on and off frequently and this wears them out making them susceptible to breakdowns. On the part of maintenance, ensure your AC unit is inspected at least annually and whenever you notice something unusual. Check the filters and have them replaced on a monthly basis. The outdoor component should be free of foliage and debris.

Forced Air Furnaces

During winter, furnaces are indispensable. They do the hardest job of heating your home and ensuring that you and your family are comfortable. Typically, a furnace should last you 20 to 30 years. However, this is possible if it is well maintained and looked after. Just like in the AC, ensure the furnace filters are changed regularly preferably on a monthly basis. The motor housing, air blower, and belts should also be cleaned and the heat registers vacuumed as needed. This will reduce wear and tear of your furnace and lengthen its lifespan.


The vinyl vent tubing of your dryer should be replaced with more durable aluminum. If used as per the manufacturer’s instructions, dryers will last you for up to 13 years. Overdriving clothes easily wear out your dryer and makes it energy inefficient. After every load, clear out the lint trap as this tends to clog the system and cause fires.

Water Heater

Water heaters come in different sizes based on your household needs. Standard water heaters are made to last between 10 and 11 years while tank-less water heating systems can last you for up to 20 year. The water heater should be drained on an annual basis and the anode replaced as required. If you can, install low-flow fixtures as this will reduce the amount of hot water flow thus saving your water heater of wear and tear.


Your refrigeration system can give you service for between 9 and 13 years. For optimal performance, it’s advisable that you do not overfill or under-fill the fridge. The refrigerator temperature should be set between 37 and 40 degrees Fahrenheit. Older refrigerator models should be vacuumed at least twice in a year and the gasket replaced if it looks cracked or worn out.

Armed with the above knowledge, it is up to you to decide how to maintain your electrical appliances and when to replace them.
