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.

Why Schedule Annual HVAC Maintenance?

Furnace Maintenance Boise

Boise and the surrounding area might still be getting hit with heat, but fall will be here before we know it. The best time to get the furnace serviced is before it’s going to be used. This makes the transition time between summer and fall the perfect time for HVAC maintenance.

5 Common HVAC Questions

HVAC Repair

Over the years, Diamond Heating and Cooling has answered many questions from homeowners regarding HVAC systems. Helping them learn more about their HVAC system and how to keep it running well is something Diamond’s technicians strive to do. Here are five of the most common questions homeowners have and the answers to them:

  1. What size of system do I need?

The answer to this question depends on factors like the size of the home. A system that’s too big or too small can increase energy bills, and decrease the lifetime of the system. Having Diamond Heating and Cooling measure the home to determine the proper HVAC system will ensure the perfect fit.

  1. How can I increase efficiency?

To keep an HVAC system running at peak efficiency, homeowners should replace the filter regularly and schedule annual maintenance with Diamond Heating and Cooling. The filter can have a huge impact on how well the HVAC system runs and maintenance catches any potential problems.

  1. How often should an HVAC system be serviced?

At Diamond Heating and Cooling, we recommended having the system serviced twice a year. The furnace should be serviced in the fall before cold weather hits and the air conditioner should be serviced in the spring. Seasons can be harsh in Boise and throughout the Treasure Valley, which can put a strain on the system, so twice a year maintenance is encouraged.

  1. How often should the filter be changed?

At the very least, the filter needs to be changed every three months. During the months when it works harder, like the middle of summer or winter, changing it every month might be needed.

  1. How much does HVAC replacement cost?

Again, no two houses are the same, which means system replacement costs will differ. Diamond Heating and Cooling offers many brands of HVAC systems at a straightforward price.

Dealing with Fluctuating Temperatures

Idaho experiences a significant amount of fluctuating weather and temperatures around this time of year. This can be hard for the HVAC system to keep up with. Keep your home comfortable during temperature fluctuations and save energy by following these tips:

  1. Smart Thermostat

These thermostats are one of the best ways homeowners can save energy and money. They help to gain control over comfort, and have many benefits. Smart thermostats allow for automation of heating and cooling, optimizing efficiency. Often they come with a phone app too so homeowners can adjust the temperature from anywhere. Use it to analyze energy usage to figure out how to decrease it and more.

  1. Window Treatments

Having the right window treatments can help minimize warm or cold air loss during times of fluctuation. They keep the home more comfortable without using any energy in the process.

  1. Fans

Not everyone is ready to turn on the air conditioner yet, but with 80 degree days, the house can get a little unbearable. Delay turning on the AC with the help of fans. They might not actually cool the room down, but they can make it feel cooler in whichever room they are used.

  1. Check the Weather Reports

It can be useful each morning to check what the weather is expected to be that day. This gives homeowners a heads up on how to program the thermostat and if they need to adjust it later on. Remember to turn the temperature up while away so the AC doesn’t run unnecessarily.

  1. Open the Windows

Open the windows for a few hours at night or in the morning during cooler hours instead of using the AC. Then shut them before leaving for the day and turning the AC on. The naturally cool air means the air conditioner won’t have to run as often until later when the day heats up.
