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.

If your furnace needs to be repaired, you’ll want to find a qualified heating, ventilating and air conditioning (HVAC) repair technician. Each state has its own licensing requirements; some require all HVAC technicians to have an HVAC license, while others only require someone operating an HVAC service and installation company with employees to hold a contractor’s license. For example, in Alabama, the Alabama Board of Heating Air Conditioning, and Refrigeration Contractors regulates licensing, while in Kansas there is no state regulatory body and HVAC licensing can vary by region. For simple furnace repairs like changing out a filter, a trusted handyman can probably handle the job, but a trained professional should be hired for tasks like replacing a gas valve, installing a new inducer fan motor or other critical furnace repair jobs that involve dealing with gas leaks or other dangerous conditions.

Keeping too many heat registers closed can cause heat to build up in your furnace, forcing air out of duct leaks and requiring the blowers to compensate for the added pressure. Essentially, blocking heating vents causes your furnace to work harder and longer than it is intended to work. Further, it forces air pressure to build up in your air ducts, which may both cause and worsens airflow leaks — particularly at joints and seams. Pros recommend keeping at least 80 percent of your heating registers open to prevent unnecessary air from building up in your furnace.
You can make your home more energy-efficient in several ways. Turn down the thermostat in winter; just two degrees cooler will save you money and reduce emissions by about 6 percent. You might not even feel the difference, especially at night or when you're out of the house—a programmable thermostat can help here. Draw the curtains at night to block the chill from a cold window. Keep the windows covered on sunny days during the summer, and uncover them on sunny days during the winter to benefit from some free solar heating. Reduce heat loss from ducts by sealing leaks and, where feasible, insulating ducts.
“Walter Zainey started the Greenwood Furnace Co. in the Greenwood neighborhood of Seattle in 1918 and quickly built a reputation for providing quality products and services. For years we believed Greenwood began in 1921 but only recently, May of 2017, Walter’s granddaughter shared a newspaper ad from 1968 showing that Greenwood was actually founded in 1918! When your company goes back 100 years you are bound to have mixed messages about the history but we now have an accurate founding date and founder. Thank you to the Zainey family and especially Jacklyn for taking the time to share the story with us. I am sure Walter Zainey would be proud the heritage he created is still living on.

When it comes to heater repair in Denver, a properly serviced system means significant savings for the homeowner. When a Denver heating technician inspects your system before the winter sets in, the first thing they will check is the condition of the air filters. These filters are important, because they are responsible for removing contaminants, allergens, and dust particles from the air every time the system is turned on. When the filters are clogged, expect more particles to easily pass through right into the air you breathe inside the home. The Denver heating experts will inspect and replace any filters that are no longer effective.
There are many signs that can indicate the need for professional air conditioning repair service in Seattle, WA. You may notice that your air conditioner does not cool your home evenly, or that there is a spike in your air conditioning costs. Regardless of what tips you off, it is important that your air conditioning repair services are completed properly.

If your thermostat has a small lever that moves along a calibrated scale that indicates “longer” (not the heat temperature lever), you can try adjusting this—the heat anticipator. Just set it one calibration mark closer to the “longer” setting if the furnace goes off and on too frequently or one mark away if the furnace allows room temperature to rise too high or drop too low before going on or off. It may take several hours for the thermostat to stabilize at this setting, so wait a while and then adjust it again if necessary.


High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
