-------------------------------------------------------------------------------------------------------------------------------Also pay attention to the proposal that Joe Biden has put forth in the week ending Aug. 8th, 2020, for carbon-free generated sorces of electricty into the U.S. electrical grid.

Typically if the furnace was dirty or by observation of the flames and/or carbon monoxide presence they would defer to a qualified professional in that field. 

I've seen all sort of repairs, crack packs with epoxy injections, carbon fiber, piers...

They do not burn 100% of the gas, causing some output of carbon monoxide.

I just finished paying for a electricians to install smoke alarms and carbon monoxide alarms to bring my first property up to code but It dawned on me that I could have used battery powered alarms, is either much better than the other?

Heat must be capable of maintaining 65 degrees 2. must have working plumbing and electrical 3. working smoke and carbon monoxide detectors, landlord not responsible to maintain batteries.

I can't seem to find the carbon monoxide disclosure and smoke detector disclosure. 

Assuming our homes appreciate at the same value (they were carbon copies in this example so easy assumption!)

I am having to install handrails, carbon monoxide detectors, repair minor foundation cracks, and more.What the heck is going on?

Hey guys,we purchased a 4-plex a year ago, however the tenants did not sign a lease with us rather than they stayed on a month-to-month basis.Since the CA law is very strict about smoke alarms, we just installed new fire alarms/carbon monoxide detectors at all units.
