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.  

Further you will need landscaping addressed if your not in an association with HOA fees, heat/AC service, snow removal.

I then added another one for my second heat pump.They have app that I use on my phone to control and monitor the temp and humidity.

It essentially plastic wraps the whole opening - makes a big difference heating wise on old, cracked, or leaking windows but, like Steve R. said, it is not a solution to the problem.

However, with winter looming, I didn’t want to risk sitting on it and heating it.

And the savings tend to accumulate- tenants don't have to change their own bulbs(everyone loves that,) and the lower heat output of LEDs also reduces their air conditioning bill.

Hello again.My Tenant who is an HVAC installer and Tech called me yesterday and offered me a very good deal on a full central heating and air system and install.  

With the market heated we are considering selling the unit.
