The Property Managers’ Guide to AC For Their Tenants


Depending on the geographical area of your property, you tenants will have different needs, and different laws, applying to their use of air conditioning.

The purpose of this article is to provide a general guideline to property managers like you, so they can have a quick reference for general strategies regarding AC for their tenants.

Bear in mind, of course, that Filter King is not a law firm. The advice in this column is not meant to be, nor should be regarded as, legal advice. Before changing anything about your property’s AC system, consult your lawyer.

With that out of the way, let’s get into it!

The Best Type of AC Unit for Your Tenants

The AC you choose for your tenants will depend largely on two things - first, your location within the U.S.

In the southern states, AC is an absolute necessity. Failing to provide not only makes your property essentially unrentable - it could also be against the law.

For northern states, where even summer temperatures stay manageable, there may be some wiggle room.

The second factor that will contribute to your choice in AC is your market. The AC you’ll want for luxurious Class A apartments is not the same as what you’ll want for budget Class C properties.

Let’s break down these differences some more.

For luxurious apartments, you’ll want AC as a permanent amenity. This means a thermostat on the wall and built in vents - central AC is your best option here.

While central AC is more expensive to install than, say, a window unit, it will allow you to justifiably increase rent for those who are willing and able to live with that luxury.

A central AC system is also more reliable than portable units, and is easier to repair overall. With portable or window units, each apartment has their own self-contained system for air conditioning. If one of them breaks, you may have to replace the entire system. That means replacing the cooling system, the filter, the ducts, the electrical system, the capacitors, and the connectors all in one go (since the system includes all of these parts.) Central AC, by contrast, only has one cooling system, electrical system, and some recurrent components that power the AC in several apartments. If there is a problem, replacing only one component of the entire system is often all that is necessary.

For less luxurious apartments, like Class C budget housing, wall units and portable units may be the better option. Window units or portable units are cheaper and easier to install, making your overall cost upfront lower than owning or managing a luxury property. This means rent can be lower, and you can continue to supply affordable housing to those who need it.

Often, AC for budget apartments in cooler climates can be an option provided for a cost to the tenant, or can be provided by the tenants themselves.

For rental houses, the biggest factor for the decision to offer AC is location. In the north, it can be foregone, as it traditionally has been. Of course, check your local legislature to ensure you don’t break any laws.

In the south, AC in a house, which will likely be central, is almost always the right choice.

The Finances Behind AC for your Tenants

You’re a businessperson. You operate on a set of principles - doing what's right, while maintaining a return on investment that allows you to preserve wealth for future generations and build a legacy.

Return on investment is perhaps the most important ratio for any businessperson. Defined as the gain on an investment divided by the initial cost of said investment, return on investment represents the very purpose of business and needs to be maximized while maintaining compliance with laws and an attention to ethical prudence.


It’s the nest for all other financial concepts - everything you do as a businessperson eventually comes back to return on investment. Installing AC for your tenants is no different.

The average cost of installing central air in a home is $5,500. This is certainly a sizable investment, but let's break it down to see if it's worth it.

Zillow is a great tool for landlords, both in finding estimates for properties, and because of the sheer amount of information they collect about rents and amenities.

Using this information, Zillow has clocked the average premium that renters will pay for central air to be 2.8% of rent. Of course, this encompasses a wide range of averages for specific cities. For example, in Denver, renters will only pay an additional 1.3% of rent for central AC. In Las Vegas, by contrast, renters will pay an extra 10.4% of rent for central air.

This means we must factor location into our financial analysis. In fact, let's find a specific city, south of which it becomes worth it to install central air.

First, assume we have a loan on a house that we will be renting out. The initial cost of this house was $250,000, with an interest rate of 5%, and amortization of 30 years.

This puts our mortgage around $1,300 per month. Our renters pay all utilities, but we are responsible for repairs and taxes equal to $7,000 per year, or $583.33 per month

Calculating our rent using the 50% rule, we find that $1,300 (mortgage breakeven) plus $583.33 times 2 (expenses relative to 50% rule), equals $2,466.67 per month. This implies a payback period of the value of the house of around 8.5 years. (Of course, this is an oversimplified method of calculating rent - I use it for the sake of brevity and reader convenience.)

Now, we need our tenant to pay off our $5,500 investment for AC within that 8.5 years, which means we must upcharge rent by around $55 per month. This represents just 2.23% of our rent.

According to Zillows information, Cincinnati residents will pay a 2.3% premium for central AC. This implies, with certain tolerances for market saturation etc., that any property with similar interest rates, central AC installation costs, and rent, that is further south than Cincinnati, should be outfitted with central AC.


Whew! That was pretty fast and loose. Obviously, there are a million more factors to consider, but this should give you a stepping stone for analyzing whether or not to install central AC for your tenants.

Interestingly, buying a house with central AC costs an additional amount over the cost of a house without it that is exactly the cost to install central AC in an existing house (around $5,500). That means this analysis can be used when debating whether to buy a rental house with or without central AC.
