I'll assume changing out an air handler and outside unit.

The dogs here (and elsewhere) are $175+/hr. and the meter starts/stops when the handler starts/ends deployment.

It sounds like you have one air handler for multiple apartments/units.  

All the duct work is installed just need the compressor and air handler installed.Thanks in Advance, Joe Garvin- 704.778.552

Like @Kiran K mentioned, coil is generally referring to the thing inside of the air handler inside the home. 

As Mark McClure stated, it is possible to handle real estate part time; but there are limitations for client support unless you have a job you can walk out on at a moments notice.

One description of the difference reads:"A service dog must be individually trained to perform work or tasks directly related to the handler’s disability, while a therapy and emotional support dog merely provides comfort to an individual in some fashion."

For example, I had an air handler replacement in which the home warranty company “covered” the new unit install, however they would not pay for the Freon recovery, installation of a float switch, installation of a filter base, and other items required to bring the house up to current code.

@David FernandezTechnically your boiler is an HVAC system (heating), but I gather you are contemplating replacing the hydronic heat with forced air.If the property is in an environment where there is a significant cooling season, then the extra cost of switching to a central air handler (i.e. heat pump w/ ancillary gas for additional heat), removing the radiators and lines and installing ductwork may make longterm sense.If there is not a significant cooling season, then it would be far more economical to replace your old boiler with a new high-efficiency condensing gas boiler (~95% efficient).
