A furnace that produces chilly air can be a major issue even in the spring. Here are some major reasons why you might be experiencing a cold or hot air breeze inside your house after turning on the heat. We’ll also provide you with a few suggested DIY remedies for a heater that isn’t doing its job since we don’t want you to be left in the dark.
Problems With the Thermostat
Sometimes it’s not your furnace’s issue that your heater sends an Icy chill rather than the heat you want. The thermostat may be causing these issues. Concentrate the early diagnostic efforts here, as you have the best possible chance of resolving the issue without involving a specialist. Thermostat problems come in various kinds, each with its solutions. These vary from the noticeable face-palm to the slightly more complex and professional. You can call an air duct cleaning Gainesville GA professional if the problem is with dirty ducts. Here are their details:
1. Fan is On
The fan is turned on, and if the fan is set to blow constantly, it will produce chilly air at a certain time. The reasoning is simple: furnaces do not continuously push out hot air. When the thermostat indicates that you need hot air, it sends it through your ducts. Whenever the ambient temperature hits the value you’ve chosen, the furnace can turn off until the air temperature dips below your selected value. However, if the fan is on all the time, it will blow frigid air during the furnace’s inactivity. As a result, set the fan to automatic to work in tandem with the furnace, and you’ll only get hot air instead of icy.
2. Thermostat Adjustment
If you’ve ever worked in a place where somebody has turned the air conditioning up to the detriment of others, you’ll understand what I’m talking about. We all have various tolerances for cold, and we all have different conceptions about how cozy the home should be.
Thermostat battles can easily lead to anyone hitting the fan’s setting to “on” by accident. And, because you’ve just observed, it can lead the ducts to produce cold air. It’s time to have a group discussion on compromise.
3. Low Battery
In addition to other stupid common errors with their thermostat, a weak battery is readily fixed. Some thermostats are powered by the home’s centralized power supply, while a self-contained battery unit powers others. That’s the type that will frequently run low and, as a result, will need to be monitored occasionally. Even a moderate condition that isn’t nearly dead can cause issues. It does not have to be entirely dead to provoke the thermostat to malfunction.
However, because the thermostat battery lasts a long time, it’s more likely to be an issue if the thermostat is old. In any case, test the cells before hiring an experienced HVAC technician; you might spare yourself some trouble.
We’ll be dealing with a significantly more complex range of furnace difficulties from here on out. They’re not typically triggered by operator error; therefore, they’re more likely to demand external assistance than the issues you’ve seen thus far.
4. DIY Thermostat Setup
Throughout the DIY thermostat setup, you overlooked something. When installing a new thermostat, some people prefer to hire a professional, while others prefer to do it themselves. The issue is pretty common, given the tremendous rise in popularity of smart thermostats over the last several years.
We’ve seen several customers purchase a fantastic new thermostat only to discover that it is incompatible with their home’s existing heating system. If you think that’s what occurred in your situation, the next step is to contact an HVAC specialist who can tell you what’s going on. Even though you’ve made a complete terrible mess with a jumbled-together system of DIY parts, a pro would be able to manage it all out and figure out what’s creating the thermostat problems.
There is one other operator error that can be causing you chilly air problems. There’s one more simple fix once you’ve verified the batteries. And inspected the other household members for sneaky thermostat-adjusting actions: replace the filter in the heating unit. A blocked filter is unclean and old, and it can hinder air movement to an HVAC system. You can get a household vent cleaning service for this problem. As a result, your furnace’s capacity to make and transport hot air around your house may be hampered. Some furnaces even include a built-in shutdown that activates when the filter becomes blocked, preventing the burner from overheating.
The furnace will then start blowing cold air. Filters are inexpensive and simple to replace. If yours is mud-colored, it’s a dead giveaway that it’s necessary to replace it. Activate your furnace after that and wait a few moments for the cooler air in the ductwork to pass through, then check to see if it begins to warm up. If that’s the case, congratulate yourself on figuring out a way without having to hire a professional. If removing the filter and rebooting the system doesn’t work, there are a few further options.
High Limit Switch Issues
A clogged filter might cause sections of the HVAC unit to fail if left unattended. It can withstand some cycles of overheating, but not indefinitely. Overheating a high-limit switch can cause it to fail. You don’t need to know how the high limit switch functions; enough to say that you wouldn’t want it to fail.
