HVAC stands for Heating, Ventilation, and Air Conditioning. The AC takes care of the cooling while the furnace takes care of the heating. Sometimes it is also referred to as the boiler. A furnace is largely used during winters, and in summers, it works alongside the central air conditioner. Clearly, one cannot live without the furnace when it is used throughout the year. Consequently, today, we shall tell you more about the warning signs that indicate you need to replace your old furnace. Being prepared will make the purchase decision easier and also help you take action in time.
Top Warning Signs That You Need To Replace Your Old Furnace
Any, one sign on its own may not be enough to declare your old furnace on the verge of going belly up. On the other hand, if you see or experience two or more of these symptoms, you may not be wrong in assuming so.
1. Furnace More Than 15 to 20 Years Old – Logically, if the furnace is already 15 to 20 years old, it is towards the end of its productive life. At such a time, you should not think too much about writing off the old furnace. If not immediately, it will become obsolete in another year or two. Replace the furnace as a planned event instead of a moment of panic.
2 .Frequent Repairs – If you have noticed that your furnace has been demanding more repairs since the last year in spite of regular maintenance, it could be indicative of your furnace nearing its end. While the repairs themselves may not be costly, but with age, obtaining the replacement parts will become harder and more expensive. So, you need to keep an eye on how often the furnace breaks down and whether the frequency is more as compared to the previous year. If the frequency is increasing, add up the cost of repairs undertaken in the past two years and evaluate whether purchasing a new furnace makes more sense.
3. Increase In Electricity Bill – As the furnace becomes older, its efficiency decreases. It starts consuming more power for performing the same level of work. As a result, there will be a steep rise in your utility bills, namely, gas and electricity. When the furnace is on its last leg, the increase in the heating bill is sharp and steady. It usually happens because the internal parts wear out and are no longer capable of working to their full capacity.
4. Strange Noises Emanating From The Furnace – When machinery is new, it runs smoothly and works silently. As it ages, it starts making noises. At first, they are low intensity, but slowly and steadily, the intensity of these noises increases so much so that they become hard to ignore. With age and steady use, various parts inside the furnace suffer from wear and tear due to which it starts making rattling, popping, squealing, or banging sounds.
5. Thermostat Unable To Maintain Comfortable Temperature – After every few days, you feel that the temperature inside the home is not the same everywhere. Some rooms are cooler than the others, or the distribution of heat is not proper. In such a case, you are repeatedly forced to fiddle with the thermostat to heat your home adequately. This is an indication that the furnace has lost the ability to distribute warm air efficiently.
6. Burner Flame Turns Yellow – When the furnace burns the fuel cleanly, its flame is blue in color. However, when the color of the flame turns yellow, it means that your furnace is unable to do so anymore. In some cases, it is representative of carbon monoxide being produced, incomplete or partial combustion, and/or leaking gas. Since carbon monoxide is a colorless, odorless, and tasteless toxic gas, any exposure to it becomes a health hazard. The important question is, how would you come to know if your furnace is producing this deadly gas? If there are lines of soot around the furnace, no upward draft can be seen in the chimney, there is more than average moisture on the cold surfaces in the home, and signs of rust appear on the flue pipes; it indicates that your furnace may be producing carbon monoxide. If you suspect this, turn
7. Home Feels Stale And Unhealthy – When the furnace is old, and on the last leg of its journey, it is unable to clean the air in your home and keep it sufficiently moist. As a result, your home feels stale, stuffy, and excessively dry. In addition to that, you will notice more dust gets accumulated inside the house, an increase in the number of static shocks, and plants will not look fresh and vibrant anymore. The discomfort is not just limited to just these. An old furnace will have a negative impact on the health of the family as well. You will notice that the members of your family suffer from airborne allergies increasingly, they will regularly complain about dry nose and skin dryness. Also, their throats will feel scratchy and itchy more often.
When To Replace The Furnace
If your furnace is more than 15 years old, the wisest choice is to buy a new one. Other than that, if you notice a combination of two or three or more of the above symptoms, it is best to call a trusted HVAC technician to access the situation and give the accurate picture. Based on what the technician advises, you can take the next step. If in doubt, call for a second opinion before making a final decision.
An old and aging furnace becomes a nuisance as well as a health hazard. Though replacing it is a big financial decision, but in the long run, it may be the best solution. When you decide to buy a new furnace, purchase from a trusted brand, and buy the latest technology. If you get confused with the choices, you can ask for a recommendation from your AC service company.
