If you think a furnace repair is impending, ask yourself these questions first:
If your answer is YES to any of these questions that are signs of an impending repair,
you may want to consider having a qualified technician inspect your furnace. Homeowners can avoid some of these concerns by having an expert inspect your furnace annually. This could help save you time, repair costs and also extend the life of your furnace.
Metal fatigue and carbon monoxide poisoning
Many furnace deaths are due to a cracked heat exchanger. Your furnace’s heat exchanger is the metal passage that separates the combustion by-products from the indoor air that is being heated. This metal is exposed to the hot flame within your furnace system and is constantly expanding and contracting as the furnace heats and cools down causing what is called ‘metal fatigue’. The metal heat exchanger can crack due to fatigue caused by this expansion and contraction.
A cracked heat exchanger is a serious issue,
as even the smallest crack can allow deadly gas to enter your home. One of the by-products of burning natural gas is carbon monoxide gas, often referred to as CO. It is an extremely difficult gas to detect, as CO is odorless, colorless and poisonous. When inhaled, CO prevents the body’s red blood cells from absorbing oxygen. When this happens over time, this can leave you with serious health issues or if inhaled in high enough concentrations, CO can be fatal.
Having regular maintenance completed by a qualified technician should help prevent this danger from occurring. We recommend that you have your furnace inspected annually by experts in this field, giving you the peace of mind that it is reliable and safe, is operating efficiently, and at the same time, keeping you and your family warm and comfortable. As part of our annual maintenance, Distinct Heating & Cooling performs a 30-Point Performance Tune Up on your HVAC System that includes testing the gas and air pressure, checking parts for damage and/or deterioration and filter replacement.
Keep it clean – as often as possible
Dirt and dust are also culprits that can cause your furnace to wear out earlier than usual requiring furnace repair. Not only can it waste natural gas, it can also lower your furnace’s efficiency and cause your furnace to overheat.
Dirt and dust can affect the three basic components of your furnace – the filter, the blower assembly and the heat exchanger.
A dirty filter will cause your furnace to work harder. It may also cause you and your family some health issues, especially if you have allergies.
Built up dirt and dust on the blower blades will reduce the furnace’s airflow and cause it to use more electricity as it works doubly hard.
With reduced airflow, the furnace will run hotter, increasing the rate of expansion and contraction of the heat exchanger which could lead to metal fatigue and cracks.
Here at Distinct Heating & Cooling, we recommend that you change your furnace filter every 2 to 3 months. This will help to prevent dirt & dust from building up in your furnace system. In turn, this will help to keep you and your family healthy & comfortable, prolong the life of your furnace system, and keep it running efficiently & reliably.
A worn out furnace will not only increase your utility bills unnecessarily, but can also be fatal to you and your family. p;Don’t wait until you experience a mechanical failure with your furnace.
