Being that you live in a cold climate where heat is required by law.

Hey Glen,I recently had a house I converted from oil to a heat pump.  

Now I am looking for a licensed plumber / heating specialist to perform the following:-pressure test on gas line-interior gas plumbing-install gas furnace-modify the existing ductwork-install 1-2 gas water heatersIf you have any recommendations for a trustworthy plumbing/heating person in the Cromwell, Hartford, or Middletown areas, please let me know.Greatly appreciated!

You don't pay for heat or trash or anything like that?

I suggest that you get a few good reliable vendors for plumbing, painting, electrical, heating, carpentry.  

The reason why is maybe it from the 1900's and they did a complete cosmetic overhaul and it looks amazing, but what about the pluming, wiring, foundation, roof, supports, heating and air conditioning, and other things that don't have anything to do with the way it looks but might have a little to do with your bottom line.

You need to calculate the utilities to light and heat the hallway, landscaping, snow removal if you have sidewalks and parking lots.  

The last step was getting the oil  furnace repaired which is responsible for heating the hot water (coil).  

As property manager I was required to get 3 bids from contractors for any major upgrades or repairs.I was required to get yearly bids for turn painting and carpet cleaning from at least 3 contractors including the one that was being used.We had a plumbing company that was always used for repairs, and heat company likewise, no bids required we called as needed and scheduled yearly service maintenance. 

I would certainly think so if you're including heat.
