Furnace Replacement – Signs That Your Furnace is Losing Efficiency

Increasing energy bills could be a sign that your furnace is losing efficiency. Also, noticing temperature shifts between different rooms could be a sign that your furnace isn’t properly distributing heat throughout your home.

Slight increases in your energy bill may not justify a furnace replacement, but drastic ones should prompt you to start shopping around. Contact Furnace Replacement Los Angeles now!

Furnaces are generally designed to last about 15 years, and although proper maintenance can help them to extend that lifespan, the fact is that at some point your furnace will reach the end of its useful life. This is why it is important to consider the age of your furnace when you are looking at the replacement options available for your home.

There are a few different ways that you can determine the age of your furnace. You can start by trying to find any paperwork or stickers that may have a date on them. You can also try to locate a manual for the system that lists the date of manufacture. If you cannot find any information like this, you can try to look for a serial number on the system. Before doing this, make sure that the unit is turned off to prevent any potential damage. The serial number will likely be somewhere on the system, such as the gas valve, electric relay, blower compartment, or fan blades. If you are unable to find the serial number, you can always conduct an internet search using the manufacturer name and the serial number to find out more.

When a furnace gets to be around 15 years old, it is probably time to start thinking about replacing it. This is because at this point, it will begin to show signs of wear and tear that will make it less efficient. This may not be apparent right away, but over time, it will make a big difference in how well the furnace works in your house.

One of the most common signs that your furnace is getting old is when it starts to make strange noises. This could include squeaking, rattling, or rumbling. These sounds usually indicate that the belt is wearing out or that there is another problem with the system. It can be difficult to repair these problems, so it is often better to simply replace the entire system.

The other thing that happens with older furnaces is that they start to lose their ability to properly clean and hydrate the air in the house. This can cause a variety of symptoms, including static shocks, drooping plants, and furniture that does not stay in tune. The best way to combat this is by having a professional replace your furnace with a newer, more efficient model.


Your furnace is a complex system that works by sucking cool air in through the bottom, heating it, and blowing it out the top. This conditioned air is then circulated throughout the house. If you’re replacing a furnace, you can leave the tubes and wires in place and simply attach the new unit to the old ones. Be careful not to break the tubes or wires when removing the old unit.

A furnace replacement will help you get a higher energy efficiency rating, which means that it converts more of the fuel it consumes into heat. A furnace with a high Annual Fuel Utilization Efficiency (AFUE) rating typically saves homeowners about $200 dollars a year on home energy costs.

Older furnaces lose their efficiency over time, especially if they haven’t been properly maintained. A sudden increase in your heating bills is a sure sign that it’s time to replace your furnace with an energy efficient model.

Changing the filter on your furnace twice a year is one of the best things you can do to maintain its efficiency. It also helps keep pollutants like pet dander, dust mites, and mold from entering the airflow. If you haven’t done this in a while, you should consider hiring a professional to change it for you.

Clogged filters force the fan motor to work harder, which can shorten its lifespan. They can also cause your CO detector to go off. This is a very dangerous situation that can lead to carbon monoxide poisoning. If your CO detector has been going off, call the fire department immediately.

If your furnace is more than 20 years old, it’s time to replace it with a more efficient model. The latest models offer better comfort and safety while lowering energy consumption. Compared to older models, they use up to 20% less energy to produce the same amount of heat.

A new furnace is also better for the environment. It emits fewer pollutants, which helps reduce greenhouse gasses in the atmosphere. It also uses less fuel, which cuts emissions from coal-fired power plants. These benefits have led the government to propose updated efficiency standards for furnaces in the United States.


A typical furnace makes some noise as it runs through a heating cycle, but the sounds should be relatively quiet and short. Anything that is excessively loud or lasting for a long time needs to be investigated immediately to prevent serious damage to the equipment. Some of these loud sounds are also a sign that your system is overdue for replacement.

Clicking noises are a normal part of the startup process, but repeated clicking throughout the heating cycle means that your furnace isn’t firing up properly. This is a dangerous issue that could potentially lead to carbon monoxide leaks, so you should contact a professional as soon as possible to get the problem fixed.

Rumbling sounds are also a sign of potential problems with your furnace, especially when they are more loud and last longer than usual. This is a sign that the heat exchanger isn’t functioning properly, which can cause carbon monoxide to leak into your home. The rumble can also be caused by loose parts in the furnace, which should also be addressed quickly to avoid further issues.

Screeching and scraping sounds are a good indicator that something is wrong with your furnace’s fan blades or motor, which can be expensive to repair. It could be a simple case of a foreign object obstructing the blower fan, or it may require some special lubrication to fix the problem. Either way, you should turn off the HVAC system right away and call a technician to inspect it for you.

Whistling sounds can be a sign of a clogged or dirty filter, but they can also indicate mechanical problems with the furnace fan. The sound can be difficult to pinpoint, as it may come from different rooms in your home. If you hear the sound coming from one specific room, it’s more likely that there is a blockage or air leak in that vent or air duct.

High-pitched squealing sounds are often the result of a loose or worn-down belt in the furnace’s blower motor. This can be a very costly repair to replace, so it’s important to catch these problems early.


Furnace replacement costs can vary depending on the type of furnace you choose, as well as the fuel source. You should factor in the cost of electricity, natural gas, heating oil and propane to determine how much your new furnace will cost to operate over its lifecycle. Energy prices fluctuate, so choosing a more energy-efficient model may help lower your monthly bills.

Another factor to consider is the location of your current furnace. Moving your furnace to a different spot in your home or building will require more labor and equipment, which increases the price. Also, if you need to upgrade or repair your ductwork, this will add to the overall cost of furnace installation.

If you are experiencing a number of issues with your existing furnace, it is probably time to replace it. A few common problems include:

Uneven heating

If you notice extreme temperature shifts in different parts of your home, it could be a sign that your furnace is no longer distributing heat evenly throughout the house. This issue can be caused by a number of reasons, such as improper ductwork or a poorly sized furnace. A hired technician should be able to identify the cause of the problem and advise you on the next steps.

Strange noises

Unusual or strange sounds coming from your furnace can indicate a mechanical problem that requires expensive repairs or a replacement. A few common sounds to look out for include rattling, popping, or screeching.

High energy bills

As your furnace ages, its efficiency declines, leading to higher energy bills. This increase in cost is usually a good indicator that it’s time to replace your furnace with a more energy-efficient model.

A yearly maintenance schedule will help extend the lifespan of your furnace and reduce the likelihood of costly repairs. A professional HVAC contractor can provide a maintenance plan and recommend the right products to keep your furnace running smoothly all year round. Additionally, comprehensive warranties offer peace of mind that your new furnace will last for years to come.

What Is HVAC?

HVAC is a system that regulates the temperature and air quality in homes and buildings. It has been widely praised for its efficiency and cost-saving capabilities.


Its primary components are the furnace (powered by natural gas, oil, or electricity) and a heat pump system. Other parts include an air handler and thermostat. For professional help, call TAP Heating And Cooling.

The heating portion of hvac is concerned with keeping the ambient temperature in a building comfortably warm. This is accomplished through a forced air system that involves the use of ductwork, registers, and an indoor fan to circulate the treated air. In a home, the most common type of HVAC system is a gas or electric furnace that heats the air through a process called convection. An ac unit also produces heat through this method, but it’s a less efficient way to do so as compared to a furnace.

While there’s more diversity in residential heating systems than there is in air conditioning, the basic premise of a hvac system remains the same. Air is drawn into the unit through an intake port and then pushed out through a blower as it’s heated. An exhaust stack vents the excess heat outdoors.

In many homes, the air intake is located near the top of the ductwork. This is where a filter should be placed to keep out debris and other contaminants. The filter should be checked and cleaned regularly to ensure proper functioning.

There are a number of different types of heaters, and each has its own pros and cons. An electric furnace has a simple, energy efficient design that requires little maintenance. On the other hand, a gas furnace is usually more expensive to operate and may require more regular maintenance. A ductless mini-split system, which doesn’t use ductwork, is a more versatile option that can save homeowners money on their utility bills.

Besides heating, a hvac system can also be equipped to dehumidify and improve the quality of indoor air. These additional features work to remove odors, spores, bacteria, viruses, and other harmful substances from the air. Some hvac systems also have air purifiers that can actually kill mold and mildew spores.

HVAC also includes the air conditioning component of a home or business, which moves refrigerated air through compressors, coils, and fans to cool the ambient temperature inside the house. This is done using outdoor units that are usually housed in a garage or shed, as well as indoor units like ductless mini-splits and air conditioners.


Cooling is the second major function of hvac. Air conditioners are powered by natural gas, oil or electricity to chill the air before it is blown into your home or office through a series of ducts. The system consists of an outdoor unit that contains the compressor and condenser, and an indoor unit that holds an evaporator coil and fan. A compressor converts refrigerant from a liquid to a gas, cooling it before it is pumped into the evaporator coil. When the refrigerant reaches a low temperature, it absorbs heat from the air in the evaporator coil and releases that cool air into your system, blowing it through the ductwork.

Some HVAC systems use a specialized type of air conditioner called a ductless mini-split system. These have a small indoor air conditioning unit, which is mounted on a wall inside your house or office, and connects to an outdoor compressor by copper tubing. The units can save up to 75% on energy costs during the summer and are often more cost-effective than a traditional central air conditioner.

The heating component of hvac is made up of different equipment types including furnaces, boilers and heat pumps. These are usually powered by fuel sources like natural gas, propane, heating oil and electricity. They work by heating a fluid that is then used to generate hot air, which is circulated throughout the house or building via ductwork.

In addition to the furnace, boiler or heat pump, an HVAC system can also consist of return and supply vents, ductwork, filters and a thermostat. Return vents are located in walls, ceilings and floors. The ductwork is a network of piping that carries air from the return vents to the air handler. Filters ensure that only clean air is pulled through the ducts and into your rooms. The thermostat is the control center of your HVAC system, allowing you to set your preferred temperature and triggering the rest of the equipment to operate according to that setting.

Some HVAC systems include a feature known as an economizer mode, which is designed to save energy by opening the outside air damper when the air in the ductwork is cooler than the desired room temperature. The control system may also open the outdoor air damper when the demand for cooling is lower than usual, depending on the specific system.


Ventilation is one of the most important parts of hvac. It ensures that the air in your home or office is fresh and clean, which is important for your health. Ventilation also helps to keep the temperature in your home or office comfortable. It also helps to reduce the amount of dust and debris in the air. If you have a ventilation system in your home or office, it is important to keep the filters clean. The best way to do this is by having them changed regularly. You can also increase the efficiency of your HVAC system by installing filters with a higher MERV rating. The MERV rating stands for Minimum Efficiency Reporting Value and it is a standard that measures how well an air filter works.

Many different systems can be used for ventilation. Some of these include natural ventilation, mechanical ventilation and energy recovery ventilation. Mechanical ventilation systems have the advantage of being able to control how much outdoor air is brought in and how it is distributed within a building. This makes it possible to create a healthy environment where people can live and work.

In addition, it is possible to use the system to save energy by only heating or cooling those rooms that are occupied. This can help to prevent energy waste in unoccupied spaces and it can make a building more environmentally friendly.

The ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) design standards for ventilation require a specific amount of fresh air to be brought into a space and exhausted from it. These standards are based on a number of factors, including how quickly the space can be decontaminated by introducing outside air and how much pollutants are generated in that space.

To avoid health problems caused by poor ventilation, it is a good idea to hire an experienced and qualified technician. When looking for a technician, be sure to ask for proof of certification. You can also check their license and insurance, as these are essential to protecting yourself. You should also look for a company that has NATE certification, which is an abbreviation of North American Technician Excellence. This is a non-profit organization that certifies technicians and trains them in the skills needed to do their jobs.


Controls are the brains behind heating, ventilation and air conditioning systems. They are the parts that interpret signals in the area and then take action to meet or exceed set temperature and humidity goals. The controls also perform important safety checks on equipment like the pilot light in furnaces and pressure switches on boilers.

In an HVAC control system, there are two kinds of input devices: sensors that measure a variable such as temperature or airflow, and actuators that convert electrical energy into some kind of mechanical force. There are also output devices that tell a controller to send a signal to the end device. Input and output devices are connected to a network infrastructure that uses twisted pair CAT-5/6 Ethernet or RS-485 cable. The CAT-5/6 Ethernet cables carry messages from the head-end software to the controllers and the RS-485 wires communicate between the controllers and the end devices.

For larger homes and buildings, HVAC controls are often folded into a building automation system (BAS) or other energy management system to coordinate operations and avoid wasted energy. For example, the BAS may use occupancy data from security systems to adjust HVAC settings before a building is occupied in order to save money on unnecessary energy usage.

With smaller, self-contained units packages, it is typical for the HVAC controller to be the thermostat. This type of control system is easy to diagnose because it only has a few components and they all connect to the controller using analog or digital outputs.

The most common way to keep a control system running smoothly is to replace the batteries regularly and to check for signs of physical damage. A good routine maintenance schedule also includes calibrating the controllers to ensure that they are functioning correctly. The most common cause of malfunctions is a loss of power, so regular checks should also include the BAS control board to make sure it has sufficient voltage and that the relays are closing properly.

In some cases, it is necessary to replace the entire control board. This is most likely to happen when one of the relays becomes faulty or the processor chips start to fail. Luckily, most modern controllers are designed to make this process as simple as possible. For example, Computrols innovative design allows the replacement of a controller in less than two minutes without having to remove the entire assembly or solder new jumpers. This innovation was a result of our extensive field experience and is just one of many features that help to simplify the process of repairing or replacing HVAC controls.
