How do furnaces work?

If you own a central air-con unit the furnace becomes part of the internal air handling unit. Nonetheless, the furnace can work independently by only relying on the air dispersal ducts to pass in the warm air. Technically furnaces function by heating the air from the collected air via the outdoor compressor. Upon heating the air is passed through a humidifier to ensure that the air passed through the rooms is not dry. Once the air has been humidified, it is then dispersed through the air ducts. This simplified explanation applies for both electric and gas furnaces although the mode of heating will differ.

Furnace repair and replacement needs and tips

Furnaces just like any other frequently used devices tend to wear out after some time. Air-Tech Systems Inc. technicians are well skilled when it comes to sorting out the following furnace problems;

Gas leaks:

If you are using a gas furnace and its efficiency dips by a huge margin, start by checking for a gas leak. Gas leaks are potentially detrimental to the safety of your house. Should you suspect one in your furnace supply system turn off the gas supply to your furnace, switch off all electric and heat points then evacuate the house. From a secure location, you can then call the fire department and a technician to plug in such a problem. If the problem is with your furnaces inability to regulate heat, switch it off and call one of our technicians to sort it out before it is too late.

Pilot light:

Old furnace with a couple lighting system not working. Do not worry. There is a handy tip on how to sort it out in the short-term. Check if the gas hole is blocked. If it uses a strip of thin wire to clean it out and make sure that the gas system is switched off before you do so. For a more concrete and satisfactory solution call us for the handiest Fairfax furnace repair s.


For electric furnaces connected to the central air-con unit, checking whether the thermostat is working is one of the first things to do. If it is not you can try to pry the keys on and off. You can also try to reset the ignition module on the thermostat. If that does not work as well, call in a technician to come over and check your flame sensors. Just an addendum on the sensor, most people prop do-it-yourself techniques, but if you do cannot do it well you stand to incur a higher cost trying to install a new one.


Dirty or worn out filters can also lead to problems on your furnace. If you realize that the problem is arising from the filter, you can get yourself one. Installing filters on most furnaces is not a huge problem. However, in more technical furnaces, don’t risk as it might not only void the warranty but could lead to clogs which can result in fires. Having a professional Fairfax furnace repair man takes the risk off your hands. It is also an easy way out of a mess that can cost you more than your property.


Some furnaces come with their own internal humidifiers, which is an ideal choice for furnaces. Nonetheless whenever there is need to replace the humidifier always do so fast. Humidifiers just like filters above are easy to replace by yourself. However, technical repairs such as linings are best left to a trustworthy technician, such as the ones you will find at Air-tech Systems Inc. Moreover, our technicians will advise you on the best choice for high-quality humidifiers to use on your furnace.
