I think oil primer is the safest bet...but my odor may have been entirely from the indoor hvac coil.  

You may have to replace the A/C or at lease do a pull and clean on the evaporator coil and blower wheel  then run the ozone generator into the duct-work. 

For the trim, you will need a miter saw, and will probably want a compressor and finish nailer. 

Working with real estate investors, price is always going to be an issue...It needs to be a balance of pricing and quality of work...Do your research of distributors in your area and find a good quality no brand name furnace and then offer to pass along savings to your customer base...We were using Goodman, now swithed over to Air Temp 92% effeciency furnace with an Airtemp AC coil, condenser, this has saved us approx. $1,000 on an entire new forced air system.

You want the one that has a coil of cable and a motor, not the short hand powerd ones.

The thieves will reach between the bars and cut through the fins of the condensing unit to get to the copper in the coil.

Although I am going with this guy for this job, I am always looking for more properties and can work with newer people if I can save some costs.I got the below pricing for a completely new system including new ductwork2 ton 14 seer AC Unit Franklin (by amana)Gas Furnace 80% 40.000 buts to 60.Evaporator coil concrete slabrefrigerant copper lines and insulation low voltage wiring for thermostat and condenser. 5 to 7 Supply air ducts boots and grill.2 return intakes grills under the unitDig. thermostat Suppl plenum Miscellaneous material to complete job10 years warranty equipment 1 year labor warranty.

Notating the pressures/temperatures of the area and unit, whether they changed the run/start caps, checked wiring, cleaned coils, and how, etc.

I had a buddy of mine who does mold inspection look at the video and he says its more than likely just dust build up and the coils just need a good cleaning which is a couple hundred vs the $1050.

Account ClosedElectric baseboard heat works the same manner as the electric resistance heat coils in the electric forced air furnaces with which you are acquainted.
