A properly functioning air conditioning system does NOT require monthly filter changes. There is something WRONG with your a/c system.
As to your original question: I know what it was and I answered it. You need to spend a few bucks and FIX the broken garbage disposal unit. If you can prove it was broken by the tenants, then bill them for it.
You are an incompetent absentee landlord.

Six Potential Problems
Here’s what can happen if you let air filter replacements fall by the wayside.
Short-Cycling: Your air conditioner is supposed to cycle on and off occasionally throughout the day, but a dirty air filter can cause those cycles to become more frequent than they need to be. Besides the noise pollution that comes with cycling, that means wasted energy and uncomfortable temperature changes.
Freezing Up: A good, clean air filter allows air to flow freely out of your unit. A dirty air filter restricts the flow of cold air, causing it to build up inside the air conditioner and lower the internal temperature. Given enough time, that buildup of cold air can eventually cause ice to form on the coils.
Uneven Cooling: Even if it’s not enough to cause freezing, that restricted airflow isn’t good for your air conditioner’s cooling power. You’ll notice uneven cooling with hot and cold spots, and that means lower comfort levels at a higher cost.
Allergen Buildup: If anyone in your home suffers from asthma or respiratory allergies, it’s especially important to keep the air filters clean. A dirty filter can cause allergens to build up in your duct system, and they’ll linger there for months. Whenever you have a forced-air system running, those allergens will be released into the air you breathe. You might even end up with a mold problem in the ducts.
General Wear and Tear: Air conditioners just last longer if they’re maintained properly. A good air filter helps to stop dust and dirt from building up on all of the unit’s internal components; a bad one will cause additional wear and tear that can lead to serious maintenance issues down the road. You may end up having to replace your air conditioner a year or two sooner, and you’ll likely be paying for expensive air conditioning repairs in the meantime.
Reduced System Efficiency: If you’re holding off on getting a replacement filter because of the cost, know that you’re only hurting your finances in the long run. An A/C unit with a dirty filter will use much more power to cool your home, and you’ll end up paying more on your utility bills.
HOW OFTEN SHOULD I CHANGE THE FILTER IN MY AIR CONDITIONER?
One of the easiest and least expensive things you can do to keep your A/C system running at its best is to change the filter every one to two months. Not only will this keep your A/C system working efficiently, but it will also improve your home’s indoor air quality.
A general rule of thumb is the more traffic your have in a home the more frequently you should change your A/C filter. If you have more than two people in your household and/or you have pets, you may want to change out your filter monthly. In particular, pet dander and pet hair can quickly block your A/C filter.
The quality of the filter you select will determine how frequently you need to change it. Most homeowners use a 1” to 3” filter and can change it every 2 months. But if you are one of the millions of Americans who suffer from allergies, you may want to consider a higher quality filter, this will cost a little more upfront but you will breathe easier and it will be well worth the cost.
If you live in a warm, dusty climate you are more likely to pick up extra debris and pollutants in the air thus causing your filter to become dirtier faster. In addition, smoking, mold or moist climates will decrease the quality of air in your home and require more frequent change outs of your filter. To keep the air in your home at its best it's best to check the filter monthly.
