Are Furnaces Safe Heating Options?

Thursday, February 19th, 2015

Furnaces are great heating systems. They’re versatile, fairly cheap, and have a high heat output. However, they also work with some pretty dangerous materials. Natural gas is obviously highly flammable, which is why it’s used as a fuel source. However, burning natural gas also produces a number of very toxic byproducts like carbon monoxide. Knowledge of these risks has led some homeowners to question whether or not furnaces are safe home heating options. Let us put those doubts to rest now. Yes, furnaces are safe heating systems, mainly because they are equipped with quite a few safety measures designed to prevent any mishaps. Let’s take a look at some of those safety features.

The Limit Switch

Overheating is one of the primary contributors to some biggest furnace problems, like a cracked heat exchanger. In order to mitigate that kind of damage, every furnace is equipped with a limit switch. The limit switch is a small device that measures the temperature inside the furnace’s plenum, or main chamber. When the temperature inside the plenum exceeds the safety limit, the limit switch activates and shuts the system down to protect it.

The Thermocouple

Most furnaces switched from a standing pilot light to an electric ignition device a long time ago. For those that still use standing pilot lights, however, the thermocouple is an indispensable safety feature. A standing pilot light is a small gas flame that burns 24/7, in case the furnace needs to be lit at any time. The flame is fed by its own gas line, which keeps it lit. However, if the flame ever blows out (which is common) there is a risk that the gas will continue to flow into the house and become a fire hazard. Enter the thermocouple. The thermocouple is a heat sensor that controls the gas valve in the line that feeds the pilot light. When it senses the heat from the pilot light, it generates an electric current that keeps the gas valve open, thus keeping the flame lit. When the pilot light goes out, the current stops flowing and the gas valve closes to prevent gas from leaking into the house.

Furnace Repair Guide: The Limit Switch

Wednesday, January 14th, 2015

Though it doesn’t get a whole lot of attention, the furnace limit switch is one of the most important parts of the entire system. Without the limit switch, your furnace would be running without a major safety measure, one that could prevent a major breakdown or even a fire. Let’s take a look at what the limit switch is, what it does, and one of the major ways in which it can warn you that something is wrong with your furnace.

What the Limit Switch Does

The furnace limit switch is a small device that is connected to the main chamber of the furnace, called the plenum. Its job is to monitor the furnace’s internal temperature. If the temperature inside the furnace plenum gets too high, the limit switch activates and shuts down the entire system. It does this in order to prevent the furnace from overheating, which could create a fire risk and cause damage to the system. Though this seems like a pretty straightforward function, there’s a reason that you need to know about it as a furnace owner. Though the limit switch can prevent the system from overheating, it does not treat the cause of the problem. That leads to a furnace behavior known as “short-cycling.”


When the limit switch shuts down the furnace, it’s really only a stopgap measure. The switch cannot diagnose or solve whatever issue is causing the temperature in the furnace plenum to rise beyond the safety limit. That means that when the furnace cools off enough to start up again, it will more than likely exceed the temperature limit again. The limit switch will then shut the system down again, and this cycle will keep going indefinitely. This places a huge amount of stress on the furnace, and if it goes on for too long it can drastically shorten its lifespan. For this reason, it is very important to call a professional immediately if you notice that your furnace is turning itself on and off over and over again throughout the day.

If you think your furnace may be overheating, call G&S Heating, Cooling & Electrical, Inc. We provide heating repair throughout North Seattle.

What Are these Noises Coming from my Furnace?

Thursday, January 8th, 2015

If you notice noises coming from your furnace, you may initially be alarmed. However, some homeowners decide that the unusual noise is not worth the stress of finding a heating service for repairs; they can deal with the noise as long as there is still a bit of heat coming from the vents. But this can be dangerous ideology, as a furnace that is in need of repair could actually break down, even if you still feel some heat in the home.

Call G&S Heating, Cooling & Electrical, Inc. for expert advice, repairs, installation, and maintenance for heating in Monroe.

Furnaces may make noises for any of several reasons, but it usually indicates a pretty serious heating issue. And when one part of your heating system is in a state of disrepair, any of the other parts may struggle as a result. You may hear any of the following from your heater this season, all of which require immediate repairs.

  • Banging: A banging noise may be a result of dirty burners. When the burners are too dirty, it could interfere with the way the system operates, causing ignition to be delayed. Delayed ignition can lead to a loud banging noise, something akin to a small explosion. Burners should only be cleaned by professionals for safety purposes and to inspect the heat exchanger for cracks that may have developed.
  • Buzzing: A buzzing noise may be the result of an electrical problem. Yes, even your gas furnace can run into electrical trouble, as it has a motor and several safety devices that all require electricity to operate. On the other hand, it could indicate a loose panel that is lightly rattling or another loose part that needs tightening. In either case, you should have a professional check it out to see if any further damage was sustained.
  • Grinding: A grinding noise most likely indicates trouble with the blower motor. The blower fan uses a motor to operate, but there are a number of factors that may affect its functionality. Whether it’s debris in the motor, an electrical error, or a motor that is simply too old, it could affect the level of heat you feel in the house.

Improving Furnace Efficiency for the Heating Season

Monday, January 5th, 2015

The heating season is in full swing, which means your utility bills have most likely soared. When you’re on a budget, nobody wants to deal with the cost that comes along with the lower outdoor temperatures, so many homeowners look for ways to save some money here and there. Unfortunately, this means many homeowners end up shutting off the heating for periods of times in order to save some money, a solution that is never ideal.

There are plenty of ways to save money without sacrificing your comfort. Don’t shut off your unit completely; heat your home to a comfortable, efficient temperature like 68 degrees Fahrenheit, call a technician, and consider taking any of the following steps.

For heating services in Marysville that can help lower your bills, call on the friendly experts at G&S Heating, Cooling & Electrical Inc.

  • Schedule Maintenance: Are your heating bills much higher than they were last year? If so, it could be because your system could simply use a little bit of maintenance. Scheduling maintenance is a great way to find out if there are any failing parts in your heating system that may need replacement soon and are contributing to higher monthly costs. A thorough cleaning and adjustment can also keep your system running almost like new as the parts can operate with ease.
  • Install Zone Control: Zone control systems allow you to regulate the temperature separately in individual areas of the home. Most likely, there are some parts of the house that don’t get used at certain times of day, often for long periods of time. A technician installs separate dampers in different areas of the ducts and each has its own thermostat. Because of this, you can shut off the heat in some areas of the home throughout the day, which helps you to save money.
  • Insulate: If you have a technician check your home, you may be surprised to find out you have inadequate insulation. Some homes are not built with enough installation or without any at all in the attic, inside walls, or around ducts. Insulation keeps heat from transferring out of your home, making you feel more comfortable and allowing your heater a break.

These services and more are available from G&S Heating, Cooling & Electrical, Inc., where you’ll find all you need to improve furnace efficiency with your Marysville heating system.

Everett HVAC Q/A: Why Won’t My Heat Pump Start?

Monday, June 11th, 2012

If you are considering heat pump repairs in Everett, you may be surprised to learn that it is probably not the heat pump that is to blame, especially if the trouble is that it simply won’t start up. That seems counterintuitive, but it’s true: the heat pump can be in perfect working order but still not turn on.

The good news, then, is that you won’t need a new heat pump and you won’t have to pay an arm and a leg to fix or replace it. Still though, these types of problems can very frustrating to diagnose and correct. Here are four common culprits when a heat pump won’t start:

  1. No power to the heat pump. Check your breaker box to see if the circuit breaker was tripped. If so, reset it and see if that fixes the problem. Another possibility is that your heat pump is wired to a wall switch, or that there is a switch on the unit itself. Make sure the switch is turned on.
  2. Make sure the thermostat is set to the proper mode, such as “heat” mode if you desire more heat. It seems overly simple, but sometimes the trouble is as simple as that.
  3. A recently replaced thermostat. If you recently upgraded or replaced the thermostat in your home, it’s possible that something went wrong that is preventing your heat pump from starting. It may be the wrong kind of thermostat – heat pumps require a specific type – or it may have been improperly wired.
  4. Finally, the heat pump may have its own circuit breaker on the air handler cabinet. This is often the case with heat pumps that have supplemental electric elements. If that breaker is tripped, that could cause the problems you are experiencing.

If you exhaust these problems and the problem persists or recurs – for example, if the circuit breaker trips again – call G & S Heating, Cooling and Electric to work on your heat pump. There may be something larger at work that is causing problems in the electrical system that controls your heat pump, and that requires some expertise to properly address.

How to Monitor Heat Flow from Furnace Registers in Mill Creek

Wednesday, March 7th, 2012

Of the many kinds of heating systems in, forced air furnaces are among the simplest in Mill Creek and monitoring the flow of heat is as simple as checking the registers and feeling the flow.

The Basics of Hot Air

At the furnace, usually in the basement or a central location, air is heated to a temperature set by the thermostat.  Once large and dominant, over the years, technological improvements have enabled furnaces to be much smaller and fit into closets.

With a fan, the warm air is circulated through a system of ducts and distributed at registers or grates usually in the floor.  A second grate takes the cooler air back to the furnace to be heated.

Water can be added at the furnace to humidify the air and filters are able to remove some of the dust that typically floats invisibly throughout a home.

Going With the Flow

While a forced air system tends to fluctuate between cycles, temperatures should be consistent throughout the home from room to room.  As heat is distributed, rooms get quickly warmer, then cool several degrees as heat dissipates until the thermostat setting starts the cycle over.

If there is poor circulation, the efficiency of the system is greatly reduced.  The furnace runs more often, adding strain and cost to the heating of your home.  Some rooms remain comfortable while the rise and fall of temperatures in others may be more radical or remain too cool.

Monitoring the Flow

By turning the thermostat higher, the furnace will engage and begin to force air to the registers.

Most registers have adjustable slats that can be rotated to allow more or less flow.  Checking to make sure all are fully open is the first step.  There is usually a lever or gear in obvious view.

Make sure all registers are free to allow air movement and not blocked by furniture or carpets.

After testing with your hand to see if there is adequate air flow, using an infrared or dial thermometer will more accurately identify if there are differences from register to register which could indicate a blockage of some sort in the vent or a problem with the system at the furnace.


Furnaces should be maintained on a yearly basis, so contact G & S Heating, Cooling, & Electric who can regularly change the filters, inspect the internal elements and ensure proper and efficient functioning of this most important part of your home.
