Let's assume you'll need a 35,000 btu unit @ $1700

the removal/installation is easy

assume $1700 or less

= $3400 or less

HE wishes might begin with simple on line shopping, e.g. Home Depot then later a high rated BBB furnace co. might have some other options you can research on Consumer Reports

Following are a few links to prior related questions which might help you with your decision - you can also find a lot of others in the Home - HVAC link in Browse Projects, at lower left, where typical ballpark costs are also discussed. Saving money through higher efficiency is a desireable goal - if it is actually cost effective.
Factors that come into play in that decision include total installed cost including cost of any modifications needed to thermostats, flues, etc (as high efficiency furnaces commonly require direct outside venting rather than the existing conventional gravity flue to the roof and new thermostatic controllers, what your time-value of money is (i.e a few percent if coming out of a bank account maybe but may be 15% if you are borrowing the money to buy it), and how long you are going to live in that home because payback time from the efficiency improvements typically takes 15-30+ years to recoup. With many of the higher-end systems, the payback time actually calculates out to longer than the expected life of the hunit unless you assume very steep energy price increases in the future. Spending an extra $5000 on a high efficiency unit to save $200/year in energy cost is common, but does not make economic sense in most cases even if your time value of money is zero. Also, spending a lot of money to gain a couple hundred dollars or so in fuel savings makes no sense if you are likely to move out of the home in a few years, because more efficient heating systems may be a listed benefit on a for-sale listing, but actually do not carry much $ value in the buyer's mind - i.e., most buyers will not pay more for a house with a 2014 80% efficiency unit than they will for a 2014 95% efficient unit, and little more for one with a 2014 95% efficient unit than for a 1990 80% efficient unit - normally just does not enter into their value picture, even in high energy consumption areas. Indeed, it has been reported that many homebuyers steer away from the highest efficiency units and especially from "green" systems like solar and heat pumps because of valid concerns about high maintenance costs and more frequent breakdowns due to their much greater complexity. I have just a bit of pity for my neighbors who replace their perfectly functioning 30+ year old 80% efficient units with $5-10,000 high efficiency units only to find the savings is only a hundred or two a year even though the loan interest alone may significantly exceed that, and their usual $125-250/year cleaning and maintenance bills go to $1000 or more due to repeated failures. I have helped several people with newer units with $1000-1500 master control board failures, when the older units in the area can have their entire control unit and gas system (controller and burners and ignitor) replaced (if needed, which very rarely is) for about $500. Not to say higher efficiency might not be good - but you needto deliverate on the numbers in earnestto figure a realistic payback period and time value of money, and you also need to realize that in many cases spending the difference in money between normal and high-efficiency units would be better spent on improved air infiltratioon control or insulation, for instance. In fact in many cases, for houses with exterior lights that are left on at night for security purposes, just replacing the incandescent bulbs with LED bulbs can pay off in much less than a year, and save $100-200 per year commonly - in many cases about the same amount an increase in efficiency from replacing the boiler would yield, for about $100-150 up front versus many thousands.
