Any system with an outdoor condenser installed at ground level requires some additional DIY maintenance. The condenser should be kept free of weeds and debris and should occasionally be gently hosed off to clear away dirt. Furnaces can be dangerous, as is true for anything involving gas and a flame.
How long a furnace will last depends on a lot of things including how it was installed and how it’s used and maintained. However, here’s a few things to keep in mind to help you decide whether to repair your furnace or replace it. Check out our interactive repair or replace tool to get an instant recommendation on your system.
Horizontal Flow Furnace
If you require professional assistance, contact us at AHWA. Once the air has been warmed inside the furnace, it gets redirected through your home via the blower fan. This part of the process is controlled and determined by the temperature settings that your thermostat dictates for various rooms in the house. Derived from the Latin word fornax, meaning oven, a furnace is a large heating appliance designed to evenly distribute heat throughout a building. The furnace’s process to create and distribute heat starts outside the building. This is where the fuel source enters the building from either a liquid propane gas storage tank or a gas supply network.
Some factors to take into account are cost, effectiveness, durability, and more. But in a lot of cases, furnace selection is largely dependent on what type of fuel you have available. Natural gas is the most popular choice, but it may not be accessible in all areas of the country.
Transferring the Heat Throughout the House
Other small exceptions will exist as well, like the fuel delivery method for oil furnaces, which disperses and atomizes the fuel before it’s consumed. Again, though, the basic steps of the heating cycle will remain the same regardless of your energy source and specific configuration. The installation costs of radiant systems tend to be even more difficult to estimate than those of forced air systems. Boiler-based systems include radiant floor heat that uses hot water, old-fashioned radiators that use steam or hot water, and also some hydronic (liquid-based) baseboard systems .
The downside is that it can get very expensive to heat a larger home with electricity. As such, electric heat is only recommended for small spaces or places with very mild winters. Heating oil is a bit different from propane and natural gas because it is actually not flammable at room temperature. In order for home heating oil to ignite in a burner, it must be first heated to 140° F and atomized through a nozzle. Only once heating oil has been heated and atomized can it be ignited in the burner.
Is the Furnace Switch or Gas Valve Off?
Once the fuel source has been delivered to the home and converted to heat, that heat must then be transferred throughout the house. In a condenser, you’ll see a primary and secondary heat exchanger to condense water vapor. If you smell gas (sometimes described as a rotten-egg smell), do not operate any electrical components. Evacuate the home and then call your utility company or fire department. Do not reenter the home until a professional has deemed it safe to do so. They will be able to test your heat exchanger for cracks, clean your pilot light, inspect the ventilation system, and much more.
Now that you know the basics of how your new furnace should work, it is vital to compare furnaces in more detail. At first glance, it may seem as if it does not matter which one you purchase as long as they heat your home. Essentially, yes, because the difference between a mobile home furnace and a regular home furnace is slight.

Types of Furnaces Based On Fan Operation
Most furnaces operate in conjunction with an air handler that connects to the supply and the return ducts. The Department of Energy has verified that improper installation can amount to up to a 30% reduction in efficiency. Frankly, based on our professional experience, that number may be generous. We’ve seen bad installations that have resulted in large repairs or even replacements after only a handful of years.
Gas Furnaces for Mobile Homes If you have access to natural gas or propane, a gas furnace is an excellent mobile home heating option. This type of furnace for trailer home layouts provides plentiful, efficient and affordable heat. Oil-based heating systems usually cost from $1,000 to $3,000, but some homeowners dislike that you have to replenish your oil supplies frequently in order to keep it running. However, this characteristic is ideal if you do not intend to live in your mobile home year-round.
Condensation produces heat, which combines with the heat from the primary exchanger and circulates via the blower. The byproduct, known as condensate, is carried away by a PVC drain that extends through the wall. A furnace is an appliance that generates heat — usually enough to supply an entire building. It does this by burning a fuel or passing electricity through resistive heating elements. Similarly, the blower motor needs to be able to operate at 60-70%, not just 100%, with a two-stage unit.
If your gas furnace shuts down frequently, try cleaning the flame sensor. Other problems are best left to pros for diagnosis and repair. Passive solar is the greenest and least expensive to operate because the sun's heat is stored in the thermal mass of the home. However, your home needs to be very well air sealed and insulated plus have adequate southern exposure to allow enough sunshine to enter the windows and warm the home.
If the heat exchanger is old or damaged, carbon monoxide may leak into the house instead of being returned to the outdoors. Carbon monoxide is dangerous to your health, even deadly. A detector is an inexpensive and easy way to keep yourself safe. Heat created in the sealed combustion chamber is transferred to the blower through a thermally conductive plate called a heat exchanger. Combustion gases exhaust through the flue, which extends through the roof into the open air. Virtually all modern furnaces are housed in rectangular metal boxes and classified by the type of fuel used.
