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.

Greg came over at 9:30pm to rescue my daughter and I from a horrible experience with Enercare that evening. He was professional. Kind. And got us what we needed quickly and at an afford price. I would 100% recommend calling on Greg and his team for any of your heating and cooling needs in the future!!

Installed a great hot water heater when our old one failed. When my furnace died during cold weather they showed up quickly and my house was warm before my wife got home. :)

I dont usually right reviews but when you receive service like this I felt it was a must. Honest and fair. I Have 4 children and on Xmas eve my furnace stopped working and a gentleman came out and got me up and running so at least we would have heat for the holidays. As promised he would replace my furnace early in the new year. The job was completed on time, great price for quality furnace and extremely clean and professional job. Would have never known anyone was in the house. Not a spec of dust or mess from lugging out an old rusty furnace. If you have any ac or heating concerns twintech is your only option. I was royally impressed with and Im sure you will be too.

This Company is terrific. No high pressure sales and they deliver exactly what they promise to deliver. The new furnace is great and we now get consistent temperatures throughout the house. The installers were great and very efficient and completed the work on schedule on the promised day. Everyone representing this company was very aware of their presence in our house and worked diligently to keep our home as uninterrupted and as clean as was humanly possible. We did not need to go around the house to clean up after they left, what a nice surprise. We have had follow up by the company to ensure everything is to our satisfaction. How unusual in today's environment. The impression left by Twintech is that they care about us and our home. This is so refreshing in today's high tech world. Out thanks go out to Dave in sales and G, G, and P (the installers).

The entire process was prompt and professional, from the initial quote to the installation of the new furnace. The team installed the new furnace and removed the old one in approx. 4 hrs. The guys were very knowledgeable and gave me lots of information. I have used Twintech before for a new A/C installation and new I was in good hands.

The overall experience dealing with this company was great from start to finish when getting a new furnace and ac this year. Everything was clearly explained to us during our consultation with Dave and there were no surprises with added costs. The work was done as expected and their response time to inquiries were very timely generally within a few hours or less. They are all very professional and was a pleasure to do business with them. Highly recommend to anyone looking for honest quality professional service.

From the initial contact we had an excellent experience with this company and all its personnel. Dave Gergley was an excellent, helpful, sales person and solicitous of our needs. He recommended only what was required and did not up sell or make any suggestions for products that we did not need, such as a new A.C. He explained the rebate process and basically outlined how to get the best furnace at the lowest price. When it was time for installation, the technicians could not have been more considerate, careful, attentive to detail, obviously committed to safety and optimum functioning of the appliance they were setting up. We have been perfectly satisfied with the functioning of the furnace and all aspects of acquiring it from the initial contact with Dave through to the installation process and follow ups inquiring about our satisfaction. Also they initiated the rebate process and contacted the appropriate inspection agency to carry it out. We highly recommend this company for all heating and cooling needs and we will contact them again when it is time to replace our A.C.

Twintech was excellent from the initial quote and throughout the install. They had a competitive rate for hot water tank and ended up buying the tank from them, had them remove the old tank and install the new one. The day of install they were prompt and out in about 2 hours. Professional , courteous really great guys. We took a look at my 30 year old furnace and they were able to offer some suggestions for future there too.
