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.

We wanted to get our AC replaced as it was 22-years old and added to this our furnace was costing more and more to repair. So, we decided to get both the furnace and AC replaced.
After going through a few quotes and product reviews we decided to go with Twintech. The three-men crew arrived early in the morning, wasted no time and got to work right away. By 2:00 pm, they were all done. Ive found their work to be top notch and they were completely professional. I had all my questions answered to my satisfaction both during the progress of their work and at end.
I have pleasure in recommending Twintech to anyone who is looking to get their furnace or Ac replaced

Our air conditioner died On a Saturday and within hours Dave came out to take a look and discuss replacement/repair options.
The new air conditioner was installed on the Wednesday. The new unit was installed quickly. The installers were friendly and cleaned up afterwards.
We noticed a slight leak around the furnace that night and they came out the next day and fixed the issue. It has been working great and is quieter than our previous unit.
Very satisfied and would highly recommend TwinTech.

I contacted TwinTech to replace my 20-year old A/C. Dave, their service rep, promptly replied and was at my home within 2 hours. He was friendly and knowledgeable and didn't try to upgrade or oversell their A/C units but suggested the best fit for my small 1000 feet bungalow. Although this was during a heatwave and very busy, they were able to fit me in 2 days later. The TwinTech crew installed a 1.5 ton Ducane A/C unit that is now running smoothly while maintaining a constant cooling temperature. The crew were very courteous, professional and efficient and I will definitely recommend TwinTech to family and friends. I much appreciated your great service.

TwinTech was a pleasure to deal with from the estimate through installation. We replaced a 28 year old a/c unit with one recommended by TwinTech's sales representative Dave who took the time to go over the product with us and answer any questions. The warranty is for 10 years parts and labour and they will complete the registration for you. Installation was by Greg (owner) and Mitch and Spencer who were quick and efficient and left everything clean and tidy.

Very professional, from the sales consultation and inspection to the final installation. Met every expectations we had for the job. A local business with great client support. We highly recommend. Twintech is a blue chip! Thanks!

I left a live chat message on their website that my air conditioning was not working. Within 1hr a representative called me to discuss my options.
The next day he came to the house to review my needs and give me a price for a new system. Price quoted was less than I expected and the installation was completed the following day. I found their salesman and the installers very knowledgeable and easy to deal with. All my questions were answered. Everything was properly explained in regards to what unit was needed and why, along with instruction where needed for use.
The installers made sure everything was working properly before they left.

This is to thank Twintech Heating and Cooling for their exceptional and timely service. Mitch, their technician was very courteous and generous with his time right from his first meeting with us. He not only took the time to check everything but also educated us on why we needed what he recommended. Greg and Mitch graciously accommodated us on our requested day and time for job to be done. They were both very courteous and responsive to our needs and special requests especially in a tight spot. The job was finished neatly and on time. Thank you Twintech for your great service !
