The days are running and getting shorter as the cold weather is approaching in speed. We must prepare for another unenjoyable time of the year as the winter period sets in many areas of the country. As such, it is essential to prepare our furnaces adequately to get through the winter again. Winter preparations entail having the checklist for a furnace replacement or make reparations where necessary.
The furnace age
Usually, furnaces work effectively for 16 – 20 years after which they can be replaced. When they reach the periphery of their life, they start having maintenance issues. However, they can operate; their efficiency is lowered thus raises electricity and gas bills.
Just like the cars, the more they age, the more they require maintenance as they breakdown frequently. Therefore, when furnaces are more than 15 years, it is wise to shop for new ones to alleviate frequent breakdown expenses. Ideally, the reparation cost is 50 percent or more the price of a new furnace. Replacing the furnace, therefore, is the best insurance to evade such unprepared charges.
On the other hand, the furnace can be operating without maintenance costs realized, but register higher electricity and gas bills. Alternatives for lowering the bills are there to spoil you. First, you can opt to update the thermostat to a programmable one, clean and update vents and duct systems, shop an electric portable heater or fireplace, and finally, you can decide to buy more blankets in the house. HVAC is the reliable advisors in making the alternatives.
However, “16-20 years is the average lifespan of a furnace at times furnaces may last longer,” says one lead technician. Reliable furnaces last between 20-30 years. The recommended lifespan of a furnace is written at the owner’s manual, but also you can consider calling the manufacturer and issue him with the unit model number to let you know exactly.
Frequent reparations and raised energy and gas bills
Usually, old furnaces tend to work hard and long to provide the same amount of heat compared to new furnaces. The longer time spent translates higher energy bills and frequent repairs. However, a slight increase in costs and reparation is recommendable for old furnaces. When the energy bills rise tremendously shopping for new furnaces is advisable. As such, you will save more from the efficient unit at the expense of older units.
Variations in temperature in house rooms served by the same furnace
Worn out furnaces do not supply heat evenly to all rooms as expected. As such, some rooms can be realized to colder and other warmer than others. This is the general behavior of furnaces as their duct systems lack the capacity to distribute heat evenly to all rooms at the same time. While experiencing such issues do not hesitate to contact HVAC experts to solve the issues.
Presence of soot around the registers
When furnaces age they begin to spew out some dust, dirt and dust particles, which irritate for individuals who wish to, keep high levels of house cleanliness and can cause some health complications. When you spot dust, dirt, and rust on the furnaces, this is a sign of production of the poisonous gas carbon monoxide. The gas most cause general house dryness, affect the walls, furniture, and plants within the house. When houseplants undergo wilting and when experiencing dry eyes, itching throats, frequent headaches it is high time to undertake urgent furnace replacement.
When the furnace produces uncommon sounds and noise
When turning on and off, furnaces usually produce some noise; however, when the noise becomes progressively louder, replacement is the best insurance for such a furnace. Popping, banging, humming and screeching is the form in which the sounds come out. The sounds indicate urgent replacement of the furnace or a given furnace part.
A rattling sound indicates the presence of unsecured duct, loose screws and sheet metals. Again, rattling suggests that the blower motor is not correctly fitted and balanced. Popping sound comes out when given parts of the furnace cool and warm depending on the furnace temperature changes within the house.
The furnace produces typically humming sound however the sound should be friendly and not loud. When the humming sound becomes louder and disruptive; therefore the motor or blower has developed a fault or started to fail. On the other hand, screeching or squealing indicate the presence of an overall concern within the blower or motor. When such sounds are produced, the motor or blower has become loose, has a deteriorating belt or has a fault with the pulley that keeps the belt intact.
In conclusion, efficient furnaces keep the home health and add some comfort required by the family. Therefore, it is essential to learn and master all the possible signs that show when the furnace has developed some complications for urgent redress. Failure to carry out immediate measures will result in increased energy and gas bill, health complications and inadequate supply of heat required within the house especially during the winter period. Replacement of furnaces at the right time saves time, energy and money.
