Today we serviced Clients in Lincoln Park, Chicago. They just came back from vacations and notice that their furnace was not providing enough heat.
Few days before leaving for vacation they experience noise coming from the furnace. They didn’t take the issue seriously thinking there is a loos metal or something in the vents. Noises are usually never a good sign when your heater kicks on. If you are hearing a knocking or banging when your heater kicks on, that is a sign that you should get your heater checked out.
We arranged for same day a service call. Our technician found issue involving the blower motor. Those can be very pricey depends of the furnace brand and model.
This furnace unit was about 17 years old and it had lock of maintenance. To put things in perspective, the average gas furnace lifespan is about 15-20 years. But more often than not, furnaces over 15 years old are no where near as efficient and cost-effective as they should be. Resulting in hefty energy bills and a greater susceptibility to future breakdowns and expensive repairs.
Our client decided to replace his old furnace with new Lennox variable speed furnace. To be honest he made wise decision. There was no reason to save his old equipment the condition of it was terrible. There was no evidence of any maintenance for at least 3 years.
So how do you know when your furnace is on its last legs and a replacement is needed? Here are several signs to watch for that may indicate it’s time to replace your old gas furnace with a new, efficient model:
1. Overall warmth issues
Is the temperature even in all rooms of your home, or are there rooms that are colder/warmer than others? Hot and cold areas indicate that your gas furnace lacks the ability to evenly distribute heated air throughout your home. This is often the first indication that its time to consider installing a new gas furnace.
2. Noisy system
When a gas furnace reaches the end of its lifespan, it frequently starts to make noises such as popping, howling, banging or clunking. If you start to hear any strange noises, schedule an appointment with an HVAC technician to identify the cause.
3. Blower motor running constantly https://www.globalheatingcooling.us
Have you noticed that your furnace’s blower motor is running excessively? This is a common symptom of an aging furnace. Often the blower will also turn off and on frequently or blow cold air.
4. Change in burner flame color
The burner flame in your furnace should be blue. If the flame is yellow or flickering, this may indicate that the furnace is unable to rid itself of poisonous carbon monoxide and you need to contact a HVAC service company promptly.
HVAC equipment doesn’t last forever and, unfortunately, all gas furnaces inevitably reach the end of their lives at some point – even with regular maintenance.
