Mini-Splits vs Window Units. Which is Right for You?

Dustin Edwards • April 3, 2024

A satisfied tenant is often a great asset to any portfolio. A happy tenant is a long-term tenant. Making sure your tenant is comfortable during the upcoming summer heat is important to keeping them happy. Today, we’ll go over the differences between mini-split and window air conditioning units so you can make the right choice for yourself and your tenant.


Upfront Cost

The upfront cost is the first difference between a window unit a/c and a mini-split system. A window unit generally costs between $200 for entry-level units and over $600 for higher-end units, including heaters. Window units are designed to sit in an open window. They tend to have fins to prevent the cold air from escaping through gaps, and occasionally, they may require some support. This makes the installation affordable and accessible and affordable for most do-it-yourself owners.


A mini-split system, on the other hand, will start at about $1000 and go up in price based on brand, power, and the amount of zones it controls. Unlike a window unit, mini-split systems aren’t nearly as DIY-friendly, meaning you'll likely need to
hire a handyman or a professional. Installation of a mini-split system is an additional cost you’ll have to consider. On average, installing a mini-split system can cost $1,000 up to over $10,000, depending on the range of sizes, efficiency rating, and brands.


Long-Term Use

The differences become significant. While the upfront cost of a mini-split system is higher, its lifespan is usually 20 years compared to a window unit’s lifespan of 10 years. At that time, running a mini-split system cost less as it was more efficient than a window unit. It's been stated that a mini-split can lower the electric bill by 40% compared to a window unit. 


Another aspect many should consider is the aesthetic and noise levels. A mini-split system is broken down into two parts: a condenser that can be installed somewhere hidden and an air handler that, when installed correctly, can blend into the walls of a room. Since the condenser is outdoors, there is little noise from the air handler inside. A window unit is all in one, meaning your tenant would not only have to sacrifice a window for it, but it is also quite loud and unattractive.


Maintenance

Much like the upfront cost, there is a significant difference between a window unit a/c and a mini-split. The maintenance for a window unit a/c includes cleaning and replacing the air filter every one to three months to ensure its efficiency. As well as filling in any gaps that may have opened up after installation. Since the coils sit outside the window, you may need to inspect and clean the outside, as dirt or debris may collect on the unit. Finally, most window unit a/c systems should not be installed year-round. They should be taken out of the window and stored correctly to safeguard it from damage when not in use.


Much like with window units, the main maintenance concern for mini-split systems is keeping them clean and minimizing obstructions. This means you should avoid having shelves or other furniture in the way of a mini-split air handler. For mini-split systems, the condenser is installed outdoors, and it also needs to be cleaned regularly every six weeks unless it was installed in a location that doesn't get too dirty.


The summer can bring with it incredibly beautiful yet hot days. If you want to ensure a long-term tenant, providing some form of cooling is a good idea.

Have you considered including utilities in your rent? Here are some of the most common utilities that help tenants see a greater value on renting your property

Your property’s roof is its first line of defense from the sun, rain, and wind. Which means it will eventually wear out. Many landlords overlook this since a roof is generally designed to last twenty or so years, and they simply forget until the signs begin to show. Below, we’ve compiled a short list of five signs it’s time to replace your roof for when doing property inspections. Tenant Complaints When your roof has become damaged, your tenants will likely be the first to notice. When tenants report water stains on the walls and ceilings, it's a sign that you should inspect your roof. In severe cases, your tenant may notice water dripping from roof leaks. This moisture, if left unchecked, can lead to the growth of mold and mildew, which can be a health concern for your tenants. Some tenants simply move out, assuming the odors or recurring respiratory issues are caused by the rental and not just the roof. This leaves you with a vacancy to manage, and if you’re unable to find the leak during this period, the following tenant may have a negative experience as well. Many landlords have found it beneficial to have property inspections regularly in order to preserve both the property’s value and the tenant’s trust. Roof’s Age Even with the highest quality materials, a roof still has a shelf life. Most roofs in Long Beach, CA, use asphalt shingles, and these generally last around twenty to twenty-five years. Once they've passed this threshold, the faults begin to show themselves. A sagging roof line is a sign that your roof is due to be replaced, as it's a serious concern. It often indicates that moisture has entered the underlying decking and caused some structural damage. From ground level, you may not be able to notice these problems. However, during an inspection of the property, an experienced inspector should be able to notice soft spots or contours on the roof. These forms of damage often get worse over time. Coordinating these inspections and preventative maintenance can be difficult for landlords with an extensive portfolio, which is why many enlist help. Shingle Damage Damaged shingles are one of the most obvious signs that your roof is deteriorating. If you ever notice cracking, curling, or patches with missing shingles, the roof is no longer providing adequate protection to your property. Although you can buy time with spot repairs, if the entire roof shows signs of damage, it’s likely time to replace the roof. Aside from protecting your property, the roof affects your property’s curb appeal. A patchy and worn-out roof can drive down the rental appeal. Prospective tenants will easily be able to spot the differences between pictures taken in the listing when compared to the property in person. This can not only hurt your chances of filling a vacancy, but it can also hurt your reputation as a landlord. Granules in Gutters After heavy rainfall, it's a good idea to inspect your rain gutters. If you or your property manager notice large amounts of black or gray granules, it means your roof shingles are breaking down. These granules are critical for shedding water off the roof. Once the granules fall off the shingle, the shingle begins to degrade faster under the sun and elements. If you’re not sure how old your roof may be, Loss of granules can be a strong indicator that your roof is nearing the end of its lifespan. Regular gutter cleaning and roof inspections can help catch these problems early before they become expensive repairs . Increase in Utility Bills Your tenants complaining about their utility bills increasing or poor temperature control in the rental may not realize the roof is to blame. A failing roof can result in subpar insulation and ventilation. This can lead to higher heating and cooling bills for your tenant. This can be frustrating for your tenants while putting more strain on the HVAC system. This puts more wear and tear on your HVAC system. Being aware of the warning signs and being proactive can protect your rental property, maintain tenant satisfaction , and avoid emergency repairs.
