The current tenant met all of our criteria, background check etc.

There will probably be a couple that bring up the point that that changing filters every month or the A/C coils freeze doesn't sound quite right, just as is being done here.Having a regular HVAC guy inspect the setup from the start would have kept this a nonissue.

If the thermostat is set too low it will develop ice/frost on the coil inside of the unit.

The most common issues are dirty air filters, bad capacitors (usually go out in summer and can be ordered for less than $10 on Amazon), bad breakers (usually trip in winter with electric step heat), dirty coils (I clean coils during tenant turnovers), bad thermostats, and low refrigerant.

I have had to clean one due to a tenant frying food all the time and clogging up the coil.  

If they did it once, they may wait for your insurance to buy you new tools and then hit you again.It used to be that way in Portland Metro but we have seen some thefts in our new construction you cant really lock them up until you get doors windows garage door.. so there is always a time were your HVAC water heater and wiring Plus tools are at risk.. we had one get hit they broke sheet rock to get the copper wire but then left a roll of wire sitting in the garage.. not the sharpest folks.In other markets like Chicago espeically south side there are protection systems one is called a DAWG google that one LOL.. basically you have to put in all metal windows and doors so in the winter you have to run portable heating to work and kegle lights In Jackson MS in the rental areas the guys working never leave any tools you pack up each day..

In my Kitimat example, I do NDT work, metal inspections, and such, so I am familiar with the work and the industry coming to that town.

Dryer must be vented to the outside.Tenant agrees to install, at his/her own expense, steel-braided washer hoses to the washer, and metal ducting to the dryer.

. $150 will get you at least 5 seasons, maybe up to 20 if you run it clean and are careful not to hit anything with it.1 - Take five minutes and check the yard for sticks, rocks, stumps, roots and hidden metal stakes (garbage too)2 - Clean the air filter every time you use it3 - Mix the gas with Seafoam or some similar gas stabilizer/cleaner - also try to run the mower out of gas every time - never buy more than 1 gallon of gas at a time as it goes bad pretty quick (or even buy just a half gallon)4 - Change the oil every year, the blade and spark plug as neededDo all that and a mower will last a very long time and continue to start very easily, unless you bought a dud.
