There are several important factors to consider when choosing a mobile home furnace. These factors will help you select a furnace that is the right size, energy-efficient, and cost-effective for your home.

  • Mobile Home Size 

First and foremost, you need to consider the size of your mobile home. A furnace that is too small will struggle to keep your home warm, while a furnace that is too large will waste energy and money.

To determine the correct size furnace for your home, you will need to consider several factors, including the square footage of your home, the insulation in your walls, and the climate where you live. The first step is to measure the square footage of your home, including all the rooms and areas that need to be heated.

Once you have determined the square footage, you will need to factor in the insulation in your walls. Good insulation will help keep heat inside your home and prevent it from escaping through the walls. If your home has poor insulation, you may need a larger furnace to compensate for the heat loss.

  • Energy Efficiency

Energy efficiency is another crucial factor to consider. An energy-efficient furnace can save you money on energy bills in the long run and reduce your carbon footprint.

The energy efficiency of a furnace is measured by its AFUE rating, which stands for Annual Fuel Utilization Efficiency. This rating tells you how much energy the furnace converts into heat. For example, a furnace with an AFUE rating of 90% will convert 90% of its fuel into heat. While the remaining 10% is lost through the venting system.

The higher the AFUE rating, the more energy-efficient the furnace is. A higher AFUE rating can save you money on energy bills in the long run. However, it may require a more significant upfront investment.

  • Fuel type

Consider the availability and cost of different fuel types in your area, such as natural gas, propane, oil, or electricity. Each fuel type has advantages and disadvantages regarding efficiency, cost, and environmental impact. Natural gas and propane are generally more energy-efficient than heating oil. 

  • Climate

The climate where your mobile home is located can impact the type and size of furnace you need. For example, homes in colder climates require a furnace with a higher heating capacity. While homes in more moderate temperatures may benefit from a heat pump system.

  • Ventilation and air quality

Ensure that the furnace you choose can be properly vented and provides adequate combustion air to maintain safe and healthy indoor air quality.

  • Noise level

If noise is a concern, look for a furnace with noise-reducing features such as insulated cabinets, variable-speed or multi-speed blower motors, and sealed combustion chambers.

  • Installation and maintenance

Consider the ease of installation and maintenance when selecting a mobile home furnace. Some furnaces may require more complex installation or frequent maintenance, affecting overall costs and convenience.

  • Cost

Consider your budget for the furnace’s upfront cost, installation, and ongoing energy and maintenance costs. Remember that a higher-efficiency furnace may have a higher initial cost but can save you money in the long run through reduced energy consumption.

Furnace for a 1500-square-foot Mobile Home

Determining the right size furnace for your 1500 square foot mobile home depends on various factors such as insulation, climate, and the layout of your home. Considering these factors, a professional HVAC technician would typically calculate load to accurately size a furnace.

However, as a general guideline, you can use the following formula to get a rough estimate of the furnace size you might need:

  1. Calculate your climate zone’s heating requirement (BTUs) per square foot. Depending on your climate, the BTU requirement typically ranges from 25 to 60 BTUs per square foot. Warmer climates require fewer BTUs, while colder temperatures require more.
  2. Multiply the BTU requirement per square foot by the total square footage of your mobile home.

For example, if you live in a moderate climate that requires 35 BTUs per square foot, the calculation would be:

35 BTUs/sq.ft. x 1,500 sq. ft. = 52,500 BTUs

This means you would need a furnace with an output of approximately 52,500 BTUs. Remember that this is only a rough estimate; a professional load calculation will provide more accurate sizing.

Quietest Furnace for a Mobile Home
