How Long Can My AC Run Before Breaking?
Posted On: May 28, 2024
The lifespan of an air conditioning (AC) unit and how long it can run continuously without breaking depends on several factors, including the type and quality of the unit, how well it is maintained, the conditions in which it operates, and usage patterns. Here are some key points to consider:
Lifespan of AC Units
- Central Air Conditioners: Typically last 12-15 years.
- Window Units: Last about 8-10 years.
- Ductless Mini-Split Systems: Generally last 12-15 years.
Continuous Operation
Most AC units are designed to handle continuous operation during periods of high demand, such as hot summer days. However, continuous operation can stress the system. Here’s what you need to know:
-
Design and Capacity:
- Proper Sizing: An AC unit that is appropriately sized for the space it cools will be able to run more efficiently and last longer.
- Overworking: If an AC unit is too small for the space, it will run continuously trying to cool the area, which can lead to premature wear and tear.
-
Maintenance:
- Regular Servicing: Routine maintenance, such as cleaning or replacing filters, checking refrigerant levels, and ensuring all parts are in good condition, is crucial.
- Professional Inspections: Having a professional inspect your AC unit annually can help catch potential problems early and extend the unit’s life.
-
Environmental Factors:
- Temperature and Humidity: Extremely high temperatures and humidity levels can make the AC work harder, reducing its lifespan.
- Air Quality: Dust and pollutants can clog filters and reduce efficiency.
-
Usage Patterns:
- Thermostat Settings: Setting the thermostat too low can cause the AC to run continuously. It’s recommended to keep the thermostat at a moderate temperature.
- Rest Periods: Giving the unit a break, even for a short time, can help reduce wear and tear.
Signs of Wear and Potential Breakdowns
- Unusual Noises: Grinding, squealing, or rattling sounds can indicate mechanical issues.
- Reduced Cooling Efficiency: If the AC isn’t cooling as effectively as it used to, it may be a sign of a problem.
- Increased Energy Bills: A sudden spike in energy costs can indicate the unit is working harder than it should be.
Tips to Prolong AC Life
- Use a Programmable Thermostat: This can help manage the AC’s workload by adjusting temperatures when you’re not home.
- Improve Home Insulation: Proper insulation reduces the load on the AC.
- Keep Vents Unobstructed: Ensure that vents and ducts are clear of obstructions to maintain good airflow.
In summary, while an AC unit can run continuously for long periods, especially during hot weather, it’s not ideal for the unit’s longevity. Proper maintenance, correct sizing, and mindful usage are key to ensuring your AC runs efficiently and lasts as long as possible. If you’re concerned about your AC’s performance or lifespan, consulting with a professional HVAC technician can provide specific insights and recommendations.

It was a refreshing experience interacting with the Twintech team. From Bob, the sales consultant, who articulated in layman's terms all the options available and reasons for making any selection. This was done without the prevailing pressure tactics so commonplace today.
Before proceeding Mitch, the technician, at our request conducted a service check on our 30 yr old furnace. His report was positive indicating no urgency to replace it. Again no pressure tactics.
Three days after first meeting with Bob, the installation team of Greg and
Spencer completed the installation within the planned time frame.
A very professional, courteous and transparent team which delivered on their promise. I highly recommend Twintech.

I had a really great experience with these guys. The salesman Bob was clearly very knowledgeable about everything to do with heating and cooling a home, spent a lot of time with us going over the details of the job, never rushed us and came back after the install to make sure we were happy. The installation crew was excellent, they covered the floors all the way from outside down to the basement furnace room, kept the place clean, got the work done on time and were very friendly. Ive got 15 years in the contracting/ construction industry and these guys are one of the most professional companys Ive dealt with. Great company!

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.
