Put on anti-puffy eye cold mask and make coffee.

My contractor wants to put a 80% efficiency furnace in the attic due to cold temperatures in the winter.  

If so, what's the best way to go about contacting-- just a cold call?

I did have one crack in an unusual cold spell a few years back, but don't worry about them much.  

A contractor just told me that since the unit is less than a year old, they won't touch it because it would void the warranty and that they probably put part of the installation on hold due to the cold.

Tracking to around 40 this year.In DC market so average profit deal is around $42K- and I wholesale about 40% and rehab about 60% of what I get.My deals overall come from:Direct mail- 50%MLS- 20%Cold Calling- 10-15%Other Investors (Mentoring Type Stuff)-15%Comments/feedback/advice welcome.

You need to get a list and either mail or cold call it.

The issues are as follows:-Power outlets in front 2 BR don't work (about 1/3 or total SF)-A/C unit does not blow cold air-There are polybutylene pipes in some of the bathrooms-1 toilet is non-functional, both toilets are not secured to the ground (per inspection report)-Bathroom fittings have leaks-Kitchen sink has leakAgain, these issues were not just left off the disclosure list they were indicated to be in perfect working order in the seller's property disclosure form that was included with the contract.  

call a HVAC guy out for bid on what you need, it's obviously hooked up to the gas and vented out so looks like a big project to switch it out,, at least you'll know before one quits working and your forced to replace in cold weather.. 

I primarily locate phone numbers for my sellers and then have my team cold call them.
