You may or may not have the technical aptitude, confidence, or your application might not really be feasible here.3 - Up-size your system - this might be a larger blower motor (check this first) - and if that's not an option, then you can move to up sizing your furnace/blower (if you're running a 'typical' split system).That's all I can think of. 

There are for or five steps going down into the basement with a motorized chair lift thingy, so it should be ADA compliant. 

now they just use it as an up-sale to get you to try and replace capacitors that have not gone bad or talk you into a new fan motor or convince you that you’re heat exchanger has pin holes so they can change it out.With that being said, there are still lots of good / smart / and ethical HVAC guys that can really provide and old school tune up and perhaps they can chime in but the newer larger companies just try to up-sell you on unneeded parts and “repairs”Tip: change your filters.

Like when my motor in my car blew up and I had to buy a new one. 

Next is about 5 tenants living in different older motor homes parked in the back yard with a gate they access for in and out (kinda like a make shift free mobile home park!

Important to distinguish the two as one heats a liquid to use for hot water/heat while the other produces electricity, so they're about as different as a steam engine and an electric motor.

With out a seasoned HVAC-R tech checking the windings of the compressor, and fan motor, I would never trust a used unit, not to mention the possibility of the coil having a leak, which you won’t even be able to test, until after the purchase.

Now it cools to 68.Another from a fixer I just bought needed a fan motor on the 12 year old AC.

@Louie Jhan Centeno Maglaque  Can you do simple repairs like replace a garbage disposer, replace a hot water heater, replace a motor or capacitor in a central air unit? 

I've used it for everything between roof repairs, A/C blower motor replacement, washer leaks, and general house cleaning/deep cleaning.
