Furnace Cleaning

Furnace Cleaning

When furnace maintenance is mentioned, most people think about getting all the components checked for issues to prevent a breakdown, but there’s an important part of maintenance that homeowners might not think about: cleaning. The furnace needs to be regularly cleaned as well as inspected to keep it working properly.

The furnace can get loaded down the dust and debris over the years, which lowers its efficiency. There are many components that need cleaned to keep it working at an optimal level. Some of these are:

  • Heat Exchanger

Heat exchangers are a very important component in the furnace. Once it becomes dirty, the heat exchanger can begin to malfunction, needing repaired or replaced.

  • Burners

Burners can fail due to contamination. If they are covered in dirt, dust, and debris, it could disrupt the flow of gas and air.

  • Flame Sensor

When the furnace is having an issue staying on, the issue is likely a dirty flame sensor. This build-up of sediment won’t allow it to work properly.

These components, plus the entire furnace cabinet are thoroughly cleaned during Diamond Heating and Cooling’s furnace maintenance services. Homeowners should not attempt to clean these components themselves because furnaces deal with electricity and gas, two items that can be harmful when handled improperly. It’s much safer to call in a professional for furnace cleaning.

Instead of a DIY cleaning job, schedule annual maintenance with Diamond Heating and Cooling. They make it easy and a bargain with the Silver Club Membership.

Frequently Asked HVAC Questions

HVAC Questions

Homeowners often have a lot of questions regarding HVAC systems, energy efficiency, and energy savings. To address some of these questions, here’s a compilation of the five most common HVAC-related questions homeowners have:

  1. How Can I Save on Energy Costs?

There are a few ways to accomplish energy savings. Here are some surefire ways to save:

  • Change the furnace filters regularly
  • Schedule annual maintenance
  • Use a programmable thermostat

 

  1. What Size HVAC Do I Need? Should I Size Up?

Bigger is not always better when it comes to HVAC systems. A system that is too large can lead to issues later. To find the right size, technicians need to measure the home to find the square footage and heating/cooling needs.

  1. Should I Repair or Replace?

There’s a lot of variables that go into this answer, but here’s a basic answer: If the system is over the age of seven and has required frequent repairs, it’s best to replace the system. Continuously repairing the HVAC system gets expensive and homeowners could save money by investing in a newer system.

  1. How Often Do Filters Need Replaced?

Dirty filters are the most common cause of system breakdowns. Simply changing out the filter is the easiest way to combat this issue. How often that should be done depends on the system and type of filter being used. In general, filters should be changed every 1-3 months. More often during winter and summer when the system is working harder.

  1. How Often Does The HVAC System Need Serviced?

For the best efficiency and energy savings, both the air conditioner and furnace should be serviced once a year. It’s optimal to get them serviced before they will be used for the season.

Hopefully this list of frequently asked HVAC questions is helpful for homeowners needing some answers about HVAC systems. For any other questions, just give Diamond Heating and Cooling a call!

Knowing When to Change the Furnace Filter

Furnace Repair Boise

Everyone knows the furnace filter needs replacing, but they might not know exactly how to tell when it needs replacing. Here are some things to look for when determining if the furnace filter needs replacing:

  • There’s built-up dust and dirt on the filter, making it grey in color
  • The house is dustier than usual
  • The HVAC system is cycling longer

Watch out for these telltale signs by:

  1. Examining the filter regularly

Often during seasons with extreme temperatures, the furnace filter will need to be changed more frequently to keep up with the HVAC demand. It’s a good idea to check the filter at a minimum of every 4 weeks during winter.

When examining the filter, check for excess dirt and grey color. Also, take note of the sound of air moving through the furnace before taking out the filter. After removing the filter, if there is a significant release of air pressure, the filter is too dirty and has lost effectiveness.

  1. Monitoring the Environment

Keep an eye on the dust level in the home. If it seems ledges and surfaces need to be dusted more often, it can be a good sign to check the furnace filter. The buildup means the filter is clogged, and can’t remove dirt and dust as well anymore.

  1. Watching for Health Issues

In homes with allergy and asthma sufferers, clean air is even more important. If allergies and asthma attacks are starting to become more frequent, the furnace filter might not be effectively doing its job. It’s time to check the filter to see if it is dirty.

The best thing homeowners can do is set up a routine with the furnace filter. Have some sort of reminder each month to check it for dirt and dust. It should be changed every three months minimum, but might require more frequent changing if the furnace has to work harder this winter.

Why Is There Water Underneath the Furnace?

If there is water pooling around the furnace, it could be a sign that something is wrong inside the furnace. The issue could be one of many problems, such as:

  1. Condensation

A condensation problem is the most common cause of water underneath and around the furnace. Both high-efficiency and standard-efficiency furnaces can experience condensation issues, but they stem from different causes. High-efficiency furnaces, also called condensing furnaces, produce condensation that is supposed to be channeled into a floor drain. If it is pooling instead, the tubing or drain could have become clogged. The tubing might also have a crack in it.

A standard-efficiency furnace is not supposed to produce any condensation. If it is producing condensation that means the flue pipe may not be properly sized and it should be corrected as soon as possible.

  1. Faulty Exchanger

Another possibility in a condensing furnace is that the secondary heat exchanger is faulty. This type of furnace usually has two or three heat exchangers instead of one like standard furnaces. If the secondary heat exchanger has a crack, water can drip out onto the floor. This problem could result in the need for a total furnace replacement.

  1. Humidifier

Some furnaces have a humidifier inside that adds moisture to the warm air blown throughout the house. This humidifier could be leaking, letting the water pool on the floor beneath it. This issue can usually be caught early on during furnace maintenance.

Don’t dismiss water pooling around the bottom of the furnace. No matter if the furnace is high efficiency or standard efficiency, it could mean there’s a serious problem that should be repaired right away. Make sure to schedule annual furnace maintenance with Diamond Heating and Cooling to catch these issues early or call us at 208-608-5050 if water is present.

What Causes Short Cycling?

When the furnace starts and stops frequently, it is call short cycling. This decreases the furnace’s efficiency and could be a sign of a serious furnace issue. However, the most common source of short cycling is a clogged air filter. Check the filter first, replacing it if necessary. If that doesn’t stop the short cycling, it could be one of the following problems causing it:

  1. Thermostat Location

If the thermostat has been poorly located, it can cause short cycling to occur. It should be placed away from drafts, effects of windows and air vents. To see if this is the issue, place something in front of the thermostat like a piece of cardboard. If the short cycling stops, it needs to be moved to a new location.

  1. Overheating

Many modern furnaces have a safety device that switches the burner off if the heat exchanger starts to overheat. This can also cause short cycling. If the heat exchanger is overheating, there’s a possibility of it being cracked, which should be repaired right away.

  1. Improper Furnace Size

Furnaces that are the wrong size for the home will short cycle trying to keep up with the desired temperature. To correct this issue, it will require a new system to be put in place that is the correct size. While expensive, it will save homeowners money on energy bills and keep the home at a more comfortable temperature.

Don’t live with a short cycling furnace. It could be increasing energy bills and not achieving the desired temperature. Continuing to let it short cycle could lead to lasting HVAC damage as well. Call Diamond Heating and Cooling if the furnace starts short cycling this fall and winter.

Also, be sure to schedule annual furnace maintenance. Check out Diamond’s Silver Club Membership and learn how to save on all things HVAC.

Finding Your Perfect Fit

Furnace Efficiency

Having a well-running, efficient furnace makes Idaho winters a lot more bearable. An efficient furnace starts with size. Bigger isn’t always better, and finding the right size is the best way to stay warm without breaking the bank. Here’s what happens when the furnace doesn’t fit the home:

Too Large

When furnace shopping, remember that bigger isn’t always better. A furnace that is too big for the building it is heating will continuously cycle on and off. This can lead to several problems. First, it creates hot and cold spots in the home because the air closest to the vents will actually become too warm while other areas, where the thermostat is located, still may not be up to temperature.  The over-sized furnace will also need maintenance more often and is likely to have a shorter life span because of the constant cycling.  It will also be costlier to operate because the furnace is least efficient when it first fires up and the constant cycling means it will be firing up more often.

Too Small

Homeowners trying to save money might consider purchasing a smaller furnace than they really need. A furnace that is too small won’t be able to heat the home comfortably. It will constantly run trying to reach that desired temperature, using up energy and costing homeowners a fortune. It will also require more maintenance over its shortened lifespan.

Finding the right size is easy with the help of Diamond Heating and Cooling. Their HVAC professionals take into consideration a number of variables to find the right size furnace. These variables are the home’s building materials, windows, size, insulation, the direction of the home and more.

One size does not fit all when it comes to furnaces, which is why the team at Diamond Heating and Cooling is here to help find the perfect fit for any home in the Boise area. Don’t go through the fall and winter with the wrong size furnace.

Call Diamond Heating and Cooling about furnace sizing, finding the perfect fit, and yearly maintenance once the furnace is installed.

5 Signs of a Cracked Heat Exchanger

Cracked Heat Exchanger

The heat exchanger in the furnace has two jobs: work with the burner to generate heat and separate toxic byproducts of combustion and vent them out. When it becomes cracked or damaged, it fails to perform these jobs, which can be dangerous to those who live in the home.

Knowing there’s a cracked heat exchanger can be difficult, but there are some signs homeowners can keep an eye out for.

  1. Difference in Flame

A normal flame in the furnace will be steady burning and blue in color. A damaged heat exchanger can make the flame dance around and be more orange or yellow in color. If this is observed, call Diamond Heating and Cooling right away.

  1. Metal Cracks

With a damaged heat exchanger, cracks can appear in the metal. While a flashlight can detect larger cracks, it is best to have a professional inspect the metal with proper equipment. It could also have excess corrosion or rust developing on the unit.

  1. Soot Buildup

If the furnace is working properly, there shouldn’t be any soot on or around the furnace’s cabinet. If it begins to build up and discolor the metal, there’s a chance the heat exchanger is cracked.

  1. Odor

In some instances, a damaged heat exchanger will manifest itself in a strong, unpleasant odor similar to the smell of formaldehyde. It can cause headaches, and is a good indication there is something wrong in the furnace.

  1. Carbon Monoxide Presence

A damaged heat exchanger leaks carbon monoxide, which is a byproduct of the combustion process. If the carbon monoxide detector in the home goes off, the heat exchanger might be broken. Call for help immediately and evacuate the home.

Call Diamond Heating and Cooling at 208-378-6624 if any of the five signs listed above are noticed. Whether the furnace has a cracked heat exchanger, or another problem, Diamond Heating and Cooling can make the necessary repairs.
