Signs Your Furnace May Be In Trouble
January 12, 2021
Let’s face it, it’s painful to call to the HVAC technician. As a homeowner and a consumer, you don’t have the training or expertise to understand what’s happening when your furnace is not satisfying your thermostat setting or even worse, when it’s not heating at all. You need to have faith that you have chosen a reputable HVAC company that is going to truly diagnose the problem and, if the problem is fixable, fix it!
At Edge Guys, we want you to feel comfortable knowing that our service technicians will always do the right thing. If your furnace can be fixed and is not past its lifespan and having repeated repair issues, we will absolutely go into MacGyver mode to get it fixed.
There are some furnace issues to be aware of that may signal real trouble ahead for your system that may require extensive service or even a replacement.
Your Furnace Is Older Than Betty White
Back in the “good old days” you would see a furnace last up to 20 years; however, as I’m sure you’ve heard, things today are not made the same as they were 20 years ago. Manufacturing has changed and for good and bad, it’s just the way it is. On the good side, furnaces today are much more energy efficient than they were 20 years ago. On the bad side, instead of 20 years, the average life expectancy of a furnace is about 12 years. If your furnace is past it’s expected lifespan and you are starting to have frequent repairs, your HVAC technician will probably recommend a replacement, and that is the correct call.
Baby It’s Cold INSIDE
Your thermostat is set at a comfortable 68 degrees but your house is sitting at a cool 65 degrees. If your furnace is over that 12 year mark, it could be a sign of a bigger furnace problem; however, it could also be a sign of a faulty thermostat. You won’t know until your technician completes a diagnostic. If it is your thermostat, the good news is that now there are many options for wifi thermostats, Nest thermostats, etc. These modern stats do pretty much do everything but rock your crying baby, so if you need a new stat, it’s not all bad!
Shake, Rattle, and Roll
A high efficiency furnace should be a nice, quiet experience. If your furnace sounds like Def Leppard is practicing in your furnace room, it’s time to give us a call.
If you hear a “banging” noise, it may be a sign of delayed ignition. This could be cause by a build up of dust and dirt or rust and corrosion built up in your system. This fix may be as simple as getting your furnace tuned up and cleaned but we won’t know until we get in and take a look.
If you hear a “clicking” noise, it could indicate there is something faulty with your gas, electrical or wiring.
A “scraping” noise may mean your blower wheel is having an issue.
“Rattling” can be something as simple as a loose screw or something as extensive as a malfunction in the furnace motor or leak in the heat exchanger.
Finally, “squealing” may be the result of a damaged blower motor.
Light My Fire
Some furnaces have a “peep hole” that allows you to see the furnace flame. If the flame is yellow this is a good indication the gas is not burning off completely. In probably indicates that the flame sensor needs to be cleaned or you have a dirty burner. Worst case scenario, you have a carbon monoxide issue. This is why it is VITAL to have a service technician out to your home to do a diagnostic.
Mickey and Minnie Belong at Disney World
Homeowners are always shocked when our technicians arrive to do a diagnostic on a furnace not working and learn the problem is a pesky pest like a rodent. You would be amazed at the damage these critters can do to your wires. A squirrel, for example, has the teeth of a chainsaw! If you are having issues with your furnace and see signs of a nest or droppings, call us….and your favorite pest control company….before the damage becomes too costly.
Don’t Go Chasing Waterfalls
If you see water around the base of your furnace it could be trouble. Many homeowners don’t know that water is a natural byproduct of a gas furnace at work. If you have a humidifier, a leaky humidifier is probably the culprit. At Edge Guys we recommend you have your humidifier serviced during your seasonal tune-up. At that time we will change your water panel and clean and clear your drain. Our humidifier service is $69 - $59 if you have a service plan.
If you don’t have a humidifier, water can be a sign of a bigger furnace issue. In many cases it is a sign that you have a cracked heat exchanger. If your heat exchanger is cracked, moisture may leak out of your furnace. If this is the diagnosis, please note that your system will be condemned and it will need to be replaced.
Avoid The Troublemakers
The best way to avoid troublemakers is to schedule bi-annual service in the form of a tune-up. At Edge Guys, our tune-ups are $89 unless you purchase a service plan for $170 (one system), in that case, two tune-ups a year are included.
If you have a service issue, a service call will cost $89 plus the repair. With a service plan you get a 15% discount on the $89 call.
Your best bet is to purchase a service agreement. You can do this by calling the office at 317-595-9720 and purchasing it over the phone. At this time, our customer service reps will also schedule your seasonal tune-up.
