The thermocouple is a copper rod that the pilot flame heats-up. When it gets hot enough, the thermocouple signals that there is enough heat to burn the gas fuel being released into the appliance—and so it allows the gas to be released to the burners. In some cases where the pilot light won’t stay lit, the thermocouple needs to be adjusted or replaced. This is generally a job for a professional.

This type of furnace is fueled by liquid propane gas, which is burned to push hot air through your home. A pilot light ignites the burners within a combustion chamber, which push heat into the heat exchanger and eventually through your entire home. Repairing this type of furnace can be more expensive than its electric alternative. For example here are some common propane gas repairs and their costs:

Don and Zac came out and assessed the furnace and explained why it was now time to replace it. Don explained in detail what we should look for (the job is bigger than his preferred scope) and the kind of furnace he recommended. When I asked him for his bill, he said, "Call it an estimate. No charge." I thanked them profusely and paid them in cookies. Affordable Furnace is a great business whose expertise and integrity you can trust.

If you pull out your home’s air filter, hold it up to a light. If you can’t see light coming through it, it’s most likely been a while since your last heating service, and likely time to get a new one. If it’s a simple disposable air filter, just replace it with a like-size new one. It’s also a good idea to write down the date you installed the new filter, so you know how old it is next time it needs to be replaced. Check the filter packaging to see how long the new air filter is supposed to be used.
Your HVAC system is an important appliance with a limited lifetime. Depending on use, with regular maintenance you can expect your furnace and air conditioner to last between 8-18 years before you will need to replace the old one. However, poor maintenance is one of the primary reasons for early replacement HVAC systems ahead of end of average life expectancy.

The price of a furnace generally rises in step with its fuel efficiency. A furnace with a 90 percent AFUE might cost $1,000 more than a similar size unit with an 80 percent AFUE. But you can often recoup that additional cost through lower fuel bills over the life of the furnace, especially in regions such as the Northeast and Midwest, where winters can be harsh. How quickly you recover the investment depends on more than just AFUE. The electricity to run furnaces with different AFUEs can vary significantly. The climate where you live, how well your home is insulated, and your local gas and electricity rates also affect payback times.
To keep your furnace in good working order it’s important to have it regularly cleaned. The national average furnace cleaning cost ranges from $60 to $80, though prices can vary greatly based on where you live in the country and what your furnace maintenance includes. An HVAC company may have different rates for different levels of furnace maintenance. For example,one company may offer general furnace maintenance for $79 and advanced maintenance for $138. Another company may offer a 38-point maintenance check for $89 and a 64-point maintenance check for $178. According to Energy.gov, a standard furnace cleaning and maintenance visit can include:

Dirty furnace filters are one of the most common causes of a furnace failure. A dirty furnace filter can limit the airflow through your furnace and cause it to overheat. If you suspect a dirty air filter, change the filter, press the reset button (if your furnace has one) and see whether your furnace begins to emit heated air. Change your furnace filters regularly — pros recommend changing them once a month — to ensure that your furnace continues to work properly. Unaddressed, dirty furnace filters can cause extensive, and expensive, damage to your home’s heating system.

An undersized heating system will, obviously, struggle to heat your home effectively. What some homeowners fail to realize is that an oversized system is no better. If your system is too big for your home, it will short–cycle which can lead to increased wear and tear or damage to your system. Schedule your heating installation in Seattle, WA with us to get the quality heating performance you need.
Among the leading ways to prevent a breakdown and make sure it runs like a lean machine is with yearly scheduled tune-ups on your furnace. Just like any mechanical equipment, the useful life of a furnace will be enhanced with preventive maintenance, by ensuring that all the elements of the unit are running efficiently. In addition, regular cleanings can help pinpoint concerns before they become big problems and you end up paying emergency rates on a cold winter night. Plus, because furnaces burn fuel to make it hot, it’s important to inspect all the various pieces to ensure there aren’t any ruptures or leaks that could impact the safety of your family. Taking the time to schedule a tune-up, even when it’s not making that odd rattling noise you’ve been ignoring, will save you time, stress, and money throughout the heating season.
