However, always make sure your filter is completely dry before re-installing it to prevent mold and mildew growth.

Ensure Proper Airflow Around the Outdoor Unit

Your outdoor unit is an essential component of your air conditioning system, and its efficiency can significantly influence the lifespan of your entire AC unit. Ensuring proper airflow around this unit is critical. This involves two key steps: removing any debris or vegetation that may be obstructing the airflow and maintaining sufficient clearance around the unit.

Implementing these measures can prevent damage to your outdoor unit and extend the lifespan of your air conditioning system.

Clear debris and vegetation

The area around your outdoor unit should be clear of any debris or vegetation. leaves, landscaping materials, and other debris can obstruct airflow and reduce the efficiency of your unit. Regularly clearing these materials can prevent damage and ensure your unit operates at its maximum capacity.

If you notice any bushes or plants growing near your unit, be sure to remove or prune them. While it might be tempting to use your outdoor unit as a landscaping feature, plants and shrubs can obstruct airflow and reduce the efficiency of your unit. Remember, your outdoor unit needs space to breathe just like you do.

Maintain adequate clearance

Maintaining sufficient clearance around your outdoor unit is just as important as keeping it free from debris. As a rule of thumb, you should aim for at least one foot of space on all sides of the unit. However, two to three feet of clearance is even better. This space allows for optimal airflow and prevents any obstructions that could reduce the efficiency of your unit.

Remember to follow the manufacturer’s instructions for your specific unit, as some models may require more clearance for proper operation.

Optimize Your Thermostat Settings

Your thermostat is like the brain of your air conditioning system. It controls when and how your AC runs, so optimizing its settings can have a significant impact on the lifespan of your unit. By making the most of the “auto” mode and installing a smart thermostat, you can reduce the strain on your AC system and extend its life.

Let’s delve into these two strategies.

Install a smart thermostat

A smart thermostat like an Ecobee or Google Nest is a game-changer when it comes to optimizing your AC usage. These devices offer a range of additional capabilities, such as temperature and humidity-based controls, weekly scheduling, and even location-based controls. These features can help you maintain optimal AC usage and extend the average life of your air conditioning unit.

What’s more, a smart thermostat can help you save up to 15 percent on cooling costs. That’s a win for both your wallet and your AC unit’s lifespan!

Upgrade Home Insulation

Think of your home’s insulation as a protective shield for your air conditioning unit. Insulation helps keep cool air inside your home, reducing the workload on your AC system. If your insulation is inadequate, conditioned air can escape, causing your AC unit to work harder to maintain a comfortable temperature.

This frequent cycling can put additional strain on your unit’s components, reducing its lifespan. By sealing air leaks and insulating your attic, you can help your AC system perform more efficiently and extend its life.

Seal air leaks

Air leaks can be a major energy drain for your home and your AC unit. Leaks can occur around windows, doors, air vents, and other areas of your home where air can escape.  Once you’ve identified any leaks, you can seal them using caulk, weatherstripping, or expanding foam.

Sealing air leaks not only prevents conditioned cold air from escaping but also reduces the amount of unconditioned air entering your home. This means your AC unit won’t have to work as hard to cool your home, which can extend its life.

Remember, a well-sealed home is a more energy-efficient home.

Insulate walls and attic

Insulating your walls and attic is another effective way to improve your home’s energy efficiency and extend the life of your AC unit. The type of insulation you choose will depend on various factors, including the size of your home and the local climate.

If your home is particularly drafty, you may need to consider additional measures. This could involve insulating your basement or increasing the insulation in your exterior walls. Either way, improving your home’s insulation can reduce the workload on your AC unit and help extend its lifespan.

Monitor and Address Potential Leaks

While maintaining your AC unit and optimizing your home’s insulation is crucial, it’s also important to keep an eye out for potential leaks. Regularly monitoring your air conditioning system for leaks can help prevent breakdowns and extend its lifespan. This includes both refrigerant leaks and other types of leaks.

Let’s take a closer look at these two types of leaks and how you can address them.

Refrigerant leaks

Refrigerant is the lifeblood of your air conditioning system. It’s the substance that cools the air within your AC unit. Therefore, a refrigerant leak can significantly impact your unit’s performance and lifespan. Common methods for detecting a refrigerant leak include visual inspection for oil traces, using soap bubbles, pressure testing, or employing an electronic leak detector.

Addressing refrigerant leaks is crucial to maintaining your AC unit’s efficiency and preventing a complete breakdown. If you suspect a refrigerant leak, it’s important to call a professional at Quality Comfort. We can accurately diagnose and repair the leak, ensuring your AC unit continues to operate efficiently.

Other leaks

In addition to refrigerant leaks, your AC unit can also experience other types of leaks. These can occur in different components of the system, including the air ducts, and the condensate drain line. A backed-up drain line will cause a water leak which can lead to damage and indoor air quality issues.  

As with refrigerant leaks, addressing these leaks promptly can help extend the lifespan of your AC unit.

Use Alternative Cooling Methods

While your air conditioning systems play a crucial role in keeping your home cool, there are other methods you can employ to reduce the workload on your AC unit. Utilizing alternative cooling methods, such as fans, black-out curtains, and blinds. 

Ceiling fans

Ceiling fans are a simple yet effective alternative cooling method. They work by circulating the air in a room, creating a draft that cools the skin. Not only can this make a room feel cooler, but it can also help distribute cool air more evenly throughout your home when used in conjunction with your AC unit. This can reduce the strain on your AC unit, leading to potential energy savings and an extended lifespan for your AC system.

To maximize the benefits of your ceiling fans, it's important to ensure they are rotating in the correct direction. During the warmer months, your ceiling fans should rotate counterclockwise. This specific rotation helps push cool air downward, creating a refreshing breeze and effectively lowering the perceived temperature in the room by up to 4 degrees. By adjusting your ceiling fans to rotate in the right direction, you can enhance comfort and promote a cooler environment during hot weather.

Block outdoor heat

Another effective method to reduce the workload on your AC unit is to block outdoor heat from entering your home. This can be achieved through several measures, including using reflective or insulating materials on windows, installing blackout blinds or window films, and properly insulating your home to slow heat transfer from the outside.

These measures can significantly reduce the amount of heat that enters your home, reducing the amount of cooling your AC unit needs to provide. So, not only can these methods help keep your home cooler, but they can also extend the life of your air conditioning unit by reducing its workload.


In summary, extending the lifespan of your air conditioning system involves a combination of regular maintenance, efficient use, and proactive measures to reduce the workload on your AC unit. By scheduling routine maintenance, keeping your air filters clean, ensuring proper airflow around your outdoor unit, optimizing your thermostat settings, upgrading your home insulation, monitoring and addressing potential leaks, and using alternative cooling methods, you can extend the life of your AC unit and ensure it continues to provide cool comfort for years to come. Remember, a well-maintained AC unit not only lasts longer but also operates more efficiently, saving you money in the long run.
