If you are in the market for a new heating system, you should seriously consider the size of the unit you are targeting. A lot of homeowners tend to think that the bigger the furnace, the better. Unfortunately, this is not always the case. Proper furnace sizing is an important aspect of installing the right heating system in your home.

Furnaces aged 10 years or more tend to lose their efficiency and cost more to operate. They also are prone to frequent system failures, causing unnecessary stress and discomfort. When the moment comes that you need to get a replacement, you must correctly determine what size of the system you are going to buy.  In addition to the furnace’s efficiency rating, you also need to look at the type and size of the furnace you want to install in your home.

Furthermore, you must consider operational costs during times when the winter is at its coldest. Heating your home is an essential comfort, but it involves a considerable amount of money.

Many homeowners were caught in the mistake of installing furnaces that were too large for their homes. This meant that optimum efficiency was rarely achieved. The upside was that gas prices were way lower in the past compared to the present.

Higher fuel costs and other factors are the reasons why homeowners across the country are looking for heating professionals who can help them set up cost-effective, high-efficiency heating solutions for their homes.

When a Heating System is Too Large

This scenario enables the furnace to keep the house warm regardless of the outside temperature. Having said that, it also means consuming more fuel while making your home less comfortable. When the system starts, certain areas may warm up too quickly and get uncomfortably warm before the thermostat is even able to read the right temperature. If your home doesn’t have quality insulation, this heat will easily get away, causing the unit to turn itself on and off (a process called short cycling). When this happens, the furnace’s lifespan is greatly diminished.

On the brighter side, certain furnace models have a safety feature that prevents them from overheating. But still, an oversized heating system usually runs hotter than normal, which puts it closer to the temperature at which it will turn itself off. This will most likely take place when the weather outside gets very cold — a time when you would need your furnace to work round the clock.

When a Heating System is Too Small

There are also homeowners who make an error of installing a furnace that is too small for their house, thinking that it’s more economical since smaller furnaces are typically cheaper than the larger ones. If your furnace is undersized, it doesn’t have the power to properly heat your home, so it will need to run longer to increase the temperature to the point of being overloaded. This causes the unit to fail prematurely and increase your utility bills. This will also create an untimely wear and tear as a small furnace tries too hard to keep up with your home’s heating needs.

The obvious danger of putting an incorrectly sized furnace in your home is quite simple — you’ll have to replace it much sooner than if you installed a properly sized system.

Why You Should Call Only the Professionals

There are a number of factors that need to be taken into consideration when buying and installing a new heating system. One main element to take into account is the size of the space that needs to be kept warm. Not only will this determine the size of the system needed, but also the number and frequency of heating ducts to distribute the heated air throughout that space.

Only a professional HVAC technician can determine the right system that can give you optimum comfort without having to spend too much on heating.
