Common Furnace Problems



Common Furnace Problems

Your furnace is an important appliance in your home. As a homeowner, it helps to understand the things that might go wrong with some of your appliances. This way, you will not only know when to call for a furnace repair Sacramento, but you can also learn how to prevent some of them. 

After all, some of the issues that will arise with your furnace are completely avoidable. Gilmore Heating, Air and Plumbing, the best Sacramento HVAC company, shares the most common problems you will encounter with your furnace. 

Not Producing heat 

Your furnace’s job is to provide you with adequate heat throughout the cold season. Our friends over at McQuillan Brothers, St Paul HVAC company, explain that this is a big issue they see in Minnesota. The failure to produce heat is an indication that something needs fixing. There are a number of reasons why your furnace could be failing to produce heat. 

  • The wrong fan setting. This setting only allows the fan to blow air through your house but without any heat. 
  • The wrong thermostat setting. Your furnace uses a thermostat to help provide adequate heat. If the thermostat is off or not set to heat, or if the temperature setting is put too low, your furnace will not produce any heat. 
  • A faulty air filter. The air filter is important in preventing dust particles and debris from being blown inside your house. With time, the air filter will get clogged. This clogging will interfere with the supply of air to your house. This will stop the furnace from producing heat.  
  • Lack of flame for ignition. For a furnace to start working and warm up your house, the fuel has to be ignited. This is made possible by pilot light. In older furnaces, the pilot light is on continuously. Newer models, on the contrary, come with an electric ignition that ignites the pilot light at the start of every cycle. A problematic ignition prevents from lighting the flame which, in turn, affects the supply of warm air in your house. 

The furnace does not turn on automatically 

Your furnace cannot switch on without the help of your thermostat. The thermostat, on the other hand, monitors the temperatures inside your house triggers the furnace to switch on when a certain temperature is met. 

There are a number of things that could affect this system. For example, a low setting on the thermostats will mean that your furnace will only switch on if the house temperature lowers to a certain level. 

Check whether your circuit breaker is off. Sometimes, the circuit breaker could be off which hinders the automatic operation of your thermostat. If this is the case, contact Gilmore Heating, Air, and Plumbing about heating maintenance services Sacramento.

The Furnace is Leaking Water 

This happens with high-efficiency furnaces with an annual fuel utilization efficiency of over 90% (AFUE). This means that 90% of the fuel in your furnace is burnt to produce heat. 

These units usually have a cool exhaust feature, complete with a PVC exhaust pipe instead of metallic pipes. Also, the units will feature condensation pipes that collect the water produced during the burning of the fuel and drains it. 

Sometimes, and due to continued use, the condensation pipes can break or clog which allows water to pool at the bottom of the furnace. This affects the furnace’s ability to provide you with warm air and can lead to a slew of problems.

Should I Replace My Furnace?



Is it Time to Replace Your Furnace?

At Gilmore Heating, Air and Plumbing, we provide expert advice on your queries on anything heating and plumbing. Homeowners have an issue with deciding whether it would be more economical to repair their faulty heating system or replace the furnace. The answer isn’t straightforward as furnaces are of different types. However, if you’ve been searching Should I replace my furnace? then you’ve come to the right place.

Today on the blog, our Sacramento HVAC company will discuss the most common occurrences that may help you determine when you should replace your furnace with a new energy-efficient system. Our company provides furnace repair, replacement, and installation services. We would love to assist with you for your furnace replacement Sacramento needs.

Many factors need to be put into consideration in making a decision on whether to repair or replace, from sudden temperature changes to loud noises to the system’s age. Below, we discuss some of these factors.

The duration your furnace has been in use

A standard furnace is designed to function for a time span of 15 to 30 years in a house. Nevertheless, experienced Sacramento heating and air conditioning experts advise that you start searching for a replacement furnace if your furnace has passed the 15-year mark. The usability of an aged furnace also depends on the fuel type it uses to heat your dwelling. Many people prefer installing an electric furnace. This is because they have a longer lifespan between 20 to 30 years. Gas furnaces, however, have a 15-20 year usability range. 

Despite gas furnaces having a shorter lifespan, fewer funds are used to keep them in operation. This is in comparison to the new electric furnaces. When compared with electric systems, gas furnaces are noted to circulate heat in your home at a faster rate. 

To extend your furnace’s usability, continually replace dirty filters to ensure it operates at its optimum level. Additionally, if you would like to stop heat from escaping from your home, we recommend sealing the doors and windows or invest in an adjustable thermostat to increase the efficiency of your furnace. If you’d prefer to replace your furnace, get in touch with furnace replacement Sacramento technicians.

Is your furnace producing loud noises while it’s in operation?

There are many different sounds that may show a serious issue with your old electric or gas furnace. Humming, rattling, clicking, screeching, popping or booming noises indicate that you require a new furnace. For example, rattling sounds may be caused by loose equipment or ducts. Please get in touch with an expert HVAC Sacramento contractor to find out whether you should replace your furnace or perform needed repairs. 

A booming sound may be an indication of a dangerous gas emission problem with your furnace. The noise is often caused by a short hold-up in the ignition process. A lingering gas odor smell is dangerous and a clear indicator that it might be time to employ a professional to install a new furnace in your home.

If you would prefer other options, consider changing to other heating sources like heat pumps, ductless mini-split systems, boilers, radiant heating, or zone control systems.

Is your temperature fluctuating?

Our neighbors over at Headwaters Construction, Sacramento commercial builders, explain that changes in the temperature of different rooms in your house are a clear indication that it might be time to start scouting for new furnaces. At Gilmore, we’ve seen that furnaces that are older than 15 years lose their efficiency slowly. They also lose their ability to disperse heat evenly throughout your home the longer they remain in operation. 

Is soot accumulating near your furnace register?

Dust and soot are generally followed by dry air. Dry air can damage wood flooring, shelves, and plants. This is a clear indicator that the furnace is releasing too much carbon dioxide into the air. Soot usually accumulates mostly near the grille and the furnace register. The register is an air duct cover that regulates airflow around your house. A furnace that produces excess soot and dust needs to be replaced as soon as possible. Consider the best HVAC Sacramento company, Gilmore Heating, Air, and Plumbing for the task. 

How much is it costing you to repair your furnace and pay your energy bills?

Old furnaces do not distribute heat evenly in your home, and this leads to a rise in your energy bill every month. If the total cost of your furnace repair accounts for more than half of the cost of buying and installing a new furnace, the time has come to upgrade.

What color are your furnace flames?

An efficient furnace produces a blue flame when burning. If your furnace is producing yellow flames when burning, this shows that your furnace is producing carbon monoxide which is a toxic gas.  Yellow flames can also be an indication of an improper combustion process or a dangerous gas leak. It is vital that you contact furnace repair Sacramento experts immediately you observe yellow flames from your furnace followed by a gas odor.

Signs of Problems With Your Furnace



No one wants to deal with a furnace that is not heating. Since it never happens at a convenient time, heating failures can lead to expensive emergency repair bills. If you pay attention, you may find that your furnace has been giving you signs of a necessary repair.

Strange Smells

When your heating system kicks on for the first time in the season, you may notice the slightly charred smell of a year’s worth of dust that has made its way around the burner. That smell should only last for a cycle or two. If you notice any strange odors when your system is running, it is time to bring in a professional to have a look.

Loud Noises

Every heating system makes some amount of noise as the burner ignites or blower fans turn. However, when a system begins to fail, you may hear the scraping sound of a misaligned blower fan, the high-pitched whining of a loose motor belt, or the rattle of loose screws. Pay special attention if your system starts with a bang. This may indicate that the burner ignition is not timed correctly.

Rising Heating Bills

If the cost of your heating bill is an unpleasant surprise, it may mean that your heating system is not burning fuel efficiently. If you have a gas furnace, be sure to examine the pilot light. A burner that is running properly will burn with a blue flame. A yellow pilot light not only indicates inefficient burning, but it may also indicate excess production of carbon monoxide. If you see yellow, be sure to have your system checked by a professional right away.

How Big of a Furnace Do I Need For My Home?



 

Part of the challenge of finding the right furnace for your home is that you need to find the right size furnace. A furnace that is too small will have to run more often, running up your heating bill and placing unnecessary wear on furnace parts. A furnace that is too large will cycle on and off more frequently, and will also prematurely wear out furnace parts.

So, choosing a furnace that is appropriately sized for your home is extremely important.

The most important considerations when sizing a furnace is the size of your home, and the weather in your area.

The heat output of furnaces, especially gas furnaces, is typically measured in BTUs (British thermal units). A good rule of thumb for home heating is that you need 25 to 35 BTUs per square foot in the moderate climates that are typical throughout much of California, while you may need up to 45 BTUs per square foot in colder climates, such as those found north of Lake Tahoe.

So if you live in Sacramento in a home that is 1,600 square feet, you will need (at bare minimum) a heater that provides 40,000 BTUs of heat, based on the calculation below.

25 BTU per square foot x 1,600 square feet = 40,000 BTU

However, there are a number of other factors that affect furnace sizing, such as:

  • Orientation of your home: Does your home receive a lot of daylight in the winter, or is it in shadow?
  • Layout of your home: Does your home have a few large rooms, or many small ones? How high are the ceilings?
  • Windows and doors: How many windows and doors does your home have? Windows tend to allow more heat to escape than walls do, and doors that aren’t properly sealed will allow cool air to leak inside.
  • Insulation: Older homes often have poor insulation, which means that a furnace will have to work harder to compensate for the amount of heat radiating outside.
  • Furnace efficiency: Furnaces aren’t just rated by BTU output, but by their efficiency as well. This efficiency rating—sometimes referred to as AFUE (Annual Fuel Utilization Efficiency)—is given as a percentage, and estimates how much of the heat generated by the furnace will actually be delivered into your home. A new 40,000 BTU furnace with an efficiency rating of 97% will produce roughly 38,800 BTUs of heat per hour, while an older 55,000 BTU furnace with an efficiency of 70% will produce 38,500 BTUs per hour.

As you can see, while it’s possible to make a rough estimate based on only weather and the size of your home, there are many other variables should be considered as well. That’s why it’s advisable to have a professional furnace installer take a look.

Is It Time for a Furnace Maintenance Service Call?



The holidays are coming up, and you know what that means! Family and friends are going to be constantly bustling in and out of your home for the next few months. But wait! Something’s not right. The vents are blowing out dust and bad-smelling air, it feels stuffy and humid, and even when you turn the thermostat all the way up, the house doesn’t warm up.

Obviously, you don’t want your guests to have to feel uncomfortable in your home. And aren’t you tired of your furnace just not working right?

What are some of the most common furnace problems that plague homeowners during the winter?

Furnace blowing cool or lukewarm air. This is usually due to the fan setting on the thermostat being set to “on” rather than “auto.” This makes the HVAC fan runs all the time, even when the furnace isn’t on. It can also be due to the pilot light being out. But it may also be a more serious issue, such as the furnace overheating due to a dirty air filter.

Poor airflow through vents. This can be caused by obstructed ducting or vents, or a filter that’s clogged full of dust and grime. If possible, check to make sure that your ductwork is clean and clear of debris, and that your air filter has been replaced.

Dust and dirt blowing through vents. This may be due to something as simple as dust buildup in your HVAC ductwork, which can be remedied with some basic cleaning. Or, it may be due to something more serious, such as a leak in the ductwork, or a dirty furnace burner.

Furnace cycles frequently. This may be due to something as minor as the thermostat not being set properly, or a clogged filter. It can also be due to inadequate insulation, which fails to retain the heat produced by your furnace, forcing it to run more frequently. In some cases, this can also be due to wiring problems, thermostat malfunctions, or improperly set fan switches.

Noisy operation. Your furnace shouldn’t squeak, rattle, rumble, or make other annoying sounds. If your furnace is keeping you up at night, then there may be a mechanical issue.

Furnace not running at all. This is the most perplexing and frustrating problem at all—when your furnace just won’t work. And unfortunately, this requires the attention of a professional to properly diagnose.

If your home heating system just isn’t working right, call the furnace repair experts at Gilmore!

We guarantee our work, so don’t risk unnecessary hassle when your guests are on the way. There’s not time to spare: Call Gilmore, and let the experts handle it!
