What size furnace will best keep your loved ones comfortable at an affordable operating cost this winter is contingent upon both the unique characteristics of your house and the furnace specifications. The same system that’s installed next door may be the wrong choice for your house. Lucky for you, there are different furnace sizes and which one to choose is based on your budget and home.
An existing furnace in your own house isn’t even a dependable guide when updating to a new unit. An expert heating load calculation is the best way to precisely decide what size furnace best matches the thermal characteristics of your living space.
The heating load means the number of BTUs of heat needed to sustain a comfy indoor temperature on the average cold night. Nailing down the correct heating load isn’t a result of outdated rules-of-thumb or educated guesses. Correctly verifying accurate furnace size is a science these days. However, this wasn’t always the case.
A Rochester heating contractor renovating existing equipment in houses frequently discover that the installed heating unit is enormous for the requirements of the home. In this instance, we know that bigger isn’t better.
A furnace that provides too much output wastes energy, creating BTUs that aren’t needed. The short cycles, or the ones that turn on and off quickly, produces unexpected temperature swings. Also, short-cycling furnaces have lessened average service life and undergo component failure more often.
Today, heating loads are decided by a knowledgeable heating and cooling expert. This technician gets data inputs about these characteristics of your home which include:
- Square footage
- Solar exposure
- Number and type of windows
- Large appliances and lighting
- Weather-stripping and air-tightness of the structure
- Number of occupants
- Type and amount of insulation
- Local climate averages
- Terrain and landscaping
When the data is collected in a room-by-room survey of your house, an HVAC contractor will get a correct heating load conveyed in BTUs. Your heating professional can then check a separate database that has the performance specifications of available furnaces to recommend the best model and make.
