Size
The size of your home will dictate the size of the furnace needed. If the furnace is too small to accommodate your needs, it will have to work harder to heat the home. Purchasing a furnace that is too large can be inefficient and they are typically more expensive. The overall use of the furnace will increase energy costs. Request a load calculation before choosing the furnace for your home. This will help determine the proper size. If replacing a furnace, do not simply go with a model that is similar to the old one. Instead, do some research as the one that came with the house may not have been the proper size.
Efficiency
High efficiency furnaces can be very expensive. The payoff, though, is in the long run because they will eventually save you money on heating bills. If you live in a colder climate where the heater will be running for extended periods of time, investing in a high efficiency model may be ideal. If, however, you do not often use the system often, a less efficient model will likely save money. In order for the investment to pay off, you will have to calculate the energy savings with the additional cost of the unit. Sometimes this may take a long time to be beneficial.
Cost
After determining the size and efficiency of the unit needed, begin researching costs. Also take into consideration installation which is typically performed by a licensed HVAC contractor. Shop around for the best possible price and get several quotes for comparison. Choose the one that has the best costs with the desired features.
Buying a furnace can help reduce energy costs while keeping your home warm during cold weather. With a little research, buying a new furnace does not need to be difficult. Ensure you are buying the proper size furnace for your home. Determine the level of efficiency that will save the most money. Then, shop around and get quotes for the best price.
