Questions for Selecting a HVAC Contractor

2013-4-5 · In the next few weeks I'll be having several HVAC companies out to my house to discuss the possibilities of adding an AC (currently NG furnace only) unit, heat pump or complete new dual fuel system (I feel that that the current furnace is slightly undersized but would like to see a Manual J to donfirm). I'd like to know all of my options so that my house is comfortable without breaking the bank.

2019-11-27 · Thus, selecting a heat pump for space heating often displaces the need for a separate cooling system, as would be required for hydronic systems using boilers. EVERYONE LOVES GEO Geothermal heat pumps that extract heat from ground water, or buried earth loops, have become the "darling" of the North American HVAC market.

Oil-Fired Boilers Building America Solution Center

Residential oil-fired boilers fall in either Category III or Category IV. A Category III combustion appliance has a vent pipe that is under positive pressure and the appliance is non-condensing, meaning its flue gases only go through one heat exchanger then exit through the vent at temperatures above 140°F.
