When deciding on different heating options, it’s essential to consider how long you want your system to last. Each unit has its strengths and weaknesses — including how long it will take before you have to replace your AC unit fully.
Specialists at Star Mechanical want to share the average life expectancy of your unit so you can prepare for your next maintenance appointment and never be left without the comforts of air conditioning!
What Is The Average AC lifespan?
AC units vary in life expectancy based on how they function and where they’re located across the nation. Here are some standard HVAC systems and how long you can expect them to last.
Furnaces
Furnaces in homes will usually last 20-30 years with proper maintenance. Because they are fuel-based HVAC systems, they need proper maintenance check-ups to provide efficient fuel for the unit. Without these check-ups, your furnace may last only 10-15 years. Replacing your furnace can be expensive, so it’s crucial to maintain this kind of unit for its whole lifespan.
Boilers
Boilers are very similar to furnaces but can last slightly longer with proper maintenance. The average life expectancy for boilers is around 20-35 years.
Air Conditioners
Air conditioners have different life expectancies depending on your geographical location. In coastal areas like California, they can typically last 7-12 years because of the salt exposure in the area. In other places, they can last around 15-20 years. Wouldn’t you want to if you can get an extra five years of cooling from your unit?
Heat Pumps
Heat pumps have different lifespans than air conditioners and also lose years in coastal areas. Heat pumps usually last between 10-12 years — depending on how often they are used throughout the year. On average, they can last up to 15 years. Coastal areas can expect their heat pumps to last closer to 7-12 years.
Ductless Mini-Splits
Like air conditioners and heat pumps, you can expect a varied life expectancy for your ductless mini-splits, depending on your region. Coastal areas will still cause faster Manteca AC replacements for these kinds of HVAC systems, but they last 10-30 years outside these areas.
What Can You Do To Keep Your HVAC System Running?
You will want to keep your AC system working for its full lifespan. If it needs major maintenance, you may need to replace it sooner than you want fully — or sooner than your budget is ready! Routine maintenance is essential to keep your system running. Getting professional maintenance every so often gives our team at Star the chance to do the following:
- Clean out your unit.
- Tighten any loose screws or nuts
- Change out your air filters
- Replace any worn-out parts
- Refuel your furnace or boiler
- Recalibrate your thermostat
You’ll be able to see your unit live its entire lifespan if you continue to look after it. If you sense something is wrong with the unit, contact a professional before it turns into a more serious problem.
