Does anyone here (in NY or the colder Northeast states) have a Mitsubishi heat pump for home heating and air conditioning?

They use a vacuum vs pressure because pressure  could cause anything in the tank to get forced out. 

@Zach Fairfield  I hear ya.. on this particular subdivision. the sewer taps are at the property line when we built the roads so they were scoped pressure tested prior to sign off by city .. so the run from that point to the clean out is 25 to 30 feet max... so yes I suppose you could get a belly .... but regardless I am happy for them to do all the testing inspecting they want.

Sometimes a little pressure is good and I'm not one to shy away from the hustle.My boss also said he'd give me as much work as I wanted and able to do while working remotely, so that may help ends meet while working on closing my first deal.

Hi Uriah,I have a pressure washing business in upstate NY, I'm not sure if I know what you are referring to but I might be able to give you a couple of idea's. 

Next is the air conditioning.  

I only use the central air in my house about 5-10 days per year.

I'll have to go back through the pictures to make sure the lighting isn't reflecting the wrong image since the driveway is new and pressure washed.

Contractors and information security don't go hand in hand when it comes things like this.I would advise you make the contracts air tight as far as who is liable for what goes on while a specific contractor is "in control" of the site, and get a really good in insurance plan.A better idea would be to use an app like taskrabbit, or WeGoLook to have inspections done, and just use the cameras to get a sense of the pace work is happening at, and if your contractors are slacking off or not.

The cold air is produced in the freezer compartment and then circulates down into the fridge.
