Heating Guide: How to Get Your Furnace Ready For Winter

Monday, September 10th, 2012

As the weather gets cold outside we need to warm the inside of our Coeur d’Alene homes. So for a warm inside we need to a well-maintained furnace. Here are a few tips to maintain your furnace so that it can keep your house warm and comfortable all winter long.

Guideline #1: Clean or replace the filter

The flow of heated air from the furnace is restricted by clogging in the filter, which makes your furnace work harder and release less heat. Simply cleaning this on a regular basis can greatly increase the effectiveness and energy efficiency of your furnace.

Guideline #2: Blower motor and blower belt

The operating time of a furnace may be increased due to loose belts, which lead to less heat being produced. Thus, replacing broken or frayed belts and oiling the motor with a few drops of lubricant will smoothen it and make it work more efficiently.

Guideline #3: Blower doors replacement

The replacement of the blower doors must be done properly to ensure healthy circulation of air in the house. These doors help keep the harmful gases such as carbon monoxide from entering the air circulation in your house.

Guideline #4: Check the vents of the house

The air in the house should be circulated well and easily through the vents. The furnace may not work properly if the flow of hot air is blocked by anything from furniture to debris.

Guideline #5:  The flue

Check the flue cap that is located near the furnace and carefully examine the outside with the help of the flue cap. Make sure the flue cap is replaced properly. If the furnace is in a closet, there should be enough ventilation, preferably in the form of direct vents to the outside to allow for efficient combustion.

Guideline #6: All flammable objects to be kept away from furnace

Flammable objects should not be placed near the furnace or water heater. Boxes, clothes, paints, gasoline, aerosols and similar items are most likely to catch fire if kept near furnace.

The above mentioned guidelines will definitely help you keep your furnace clean and in good working condition so you shouldn’t face a problem in the winter months ahead.

Airway Heights Heating Guide: How to Make Your Heating System More Effective

Friday, January 20th, 2012

Everyone wants an effective heating system in Airway Heights– one that will provide steady, reliable heat without you having to spend hundreds of dollars each month on gas, oil or electricity. And while the best way to improve the efficiency of your heating system in most cases is to upgrade it, there are some simple things you can do around the house to boost its effectiveness. Here are some of the best:

  • Rearrange Furniture – Just having the heat on doesn’t necessarily ensure the heat entering your room is being distributed evenly. Move your furniture in such a way that there is a clear, unimpeded path from the registers and radiators to the rest of the room. Done properly, this will make it much easier to and faster to heat every room of your house.
  • Maximize Air Flow – Air flow can be maximized in a number of ways. Make sure you close any windows near a register or radiator and that you remove any large objects that might block air flow. You should also install things that can help move air like fans and always call someone in for changes to the arrangement of your vents or radiators.
  • Clean Registers or Radiators – The cleaner your radiators or dust registers are, the more efficiently they release their heat. Not only have that, but clean radiators and registers resulted in better indoor air quality. Weekly cleaning of each room’s heating source is highly recommended.
  • Install Ceiling Fans – Ceiling fans switched to blow down are incredibly effective for distributing air throughout the room. This will keep push warm air down and keeps cold air up – in effect, reducing the need for constant running of your furnace or boiler.

Effective heating is important to keep your home comfortable, reduce the cost of heating and prolong the lifespan of your furnace or boiler. You should also make sure your heating system is properly maintained throughout the year. Skipping maintenance visits (which are highly recommended annually) will put unnecessary stress on your system and shorten its lifespan substantially, not to mention the decrease in efficiency when heating your home.

Bayview HVAC Contractor Guide: Essential Components of a Home Comfort System

Friday, January 13th, 2012

Indoor comfort is defined by several factors: temperature, humidity, and air quality. If any one of the three is out of the “normal” range it can affect the quality of life in your Bayview home.

The ultimate goal of any heating & cooling contractor is to ensure that customers are comfortable – meaning that all three factors are addressed when servicing, replacing, or installing new equipment in a home. This equipment includes furnaces and air conditioners but also extends to humidifiers, dehumidifiers, electronic filters, ultraviolet (UV) lighting, infrared heating, etc.

Obviously, the essential component for most U.S. households is a furnace. Air conditioners may not be essential for all parts of the U.S., namely the northern states, but are still considered an integral part of any home comfort system. Add-ons like de-humidifiers and electronic filters are important for controlling the air quality.

Let’s look at the furnace first. There are several choices but most can be found in two different classifications: single-stage or variable speed two-stage. Your choice depends on the indoor square footage, your own comfort needs, and possibly the cost of energy units (gas or electric for example). Forced air is a common method of moving heated air to all parts of the home via an air handling unit and through a duct system. But gaining in popularity is radiant heat (electric), which does not utilize a duct system.

Air conditioners also come in a variety of sizes, including window/room air conditioners or central air conditioning, which is likely a “split” system including an outdoor unit and indoor coil. The size of the air conditioner is determined by square footage, which is part of a load calculation performed by qualified heating & cooling contractors while planning the equipment replacement or new installation. An oversized air conditioner may produce high humidity levels and an undersized unit may not provide enough cooling to all areas of the home. High humidity levels contribute to higher indoor temperatures in the summer, and can also lead to respiratory problems.

If someone in your home has allergies or is sensitive to certain pollutants in the air, it may be important to include extra filtration in your heating & cooling system, such as electronic filtration and UV lighting mounted in the buildings duct system, to kill germs and contaminants.

And speaking of an essential component, duct systems are keys to maximizing efficiency and comfort. Properly sized, insulated, and sealed, the duct system is a key to comfortable, healthy indoor air – and energy efficiency. It is also important to keep your duct system clean, too.

As always, it is best to consult with a licensed Bayview heating and cooling contractor who can offer the best solutions for your home comfort system.

Heating Installation Guide: What to Expect in a Low, Medium or High Efficiency Furnace

Wednesday, January 11th, 2012

When buying a new furnace in Deer Park, you have many options. You can purchase a low end model to save money up front and you’ll still get exceptional fuel efficiency, but as you go up the scale, more innovative, money saving features become available. Here is a brief look at what you can expect based on which type of furnace you purchase.

Low Efficiency Furnace

This is a bit of a misnomer as even entry level furnaces have efficiency ratings of at least 80%. For comparison, if you’re still using an old gravity furnace, your efficiency rating could be lower than 50%. Modern furnaces are built to conserve, and while you won’t receive all of the bells and whistles that tend to accompany high efficiency models, you will get a durable, affordable furnace that will last a long time.

Medium Efficiency Furnaces

Furnaces in the mid-efficiency range have AFUE ratings of between 85% and 92% and are therefore significantly better than those in the entry level range. They also have some of the higher end features available in high efficiency models like programmability and the option for zone control. Because they are still mid-range, they are affordable without skimping too much on features too – a must for any homeowner wanting to save money on both ends.

High Efficiency Furnaces

The highest efficiency furnaces on the market are very different from those you would have purchased even just 10 years ago. Top end furnaces can carry AFUE ratings of up to 95% with a boat load of added features to conserve energy. These features include two stage gas valves so you can maintain a low BTU heating system for most of the year but crank up the heat when the temperature outside drops too low. They are also programmable, which allows you to easily change the temperature settings, fan speed and more from anywhere in the house.

And while they cost more to install, high efficiency furnaces use less energy over their lifespan, last longer and are more environmentally friendly than any other furnaces on the market in Deer Park today.

A Question from Valley Ford: Why is My Furnace Turning On and Off?

Monday, December 26th, 2011

One of the most annoying things your furnace can do is to constantly keep turning on and off. This on-off cycling keeps your Valley Ford home from heating up properly. This action – called short cycling – also requires more electricity and drives up utility bills.

Short cycling is caused by an overheated furnace, which triggers safety mechanisms and shuts down the furnace. After a brief interval and cooling down, the furnace starts up again the cycle keeps repeating itself. Not only is it an annoyance, it can also signal more serious problems. A leaking heat exchanger can cause a furnace to overheat – and produce deadly carbon monoxide gas.

If a furnace is working too hard and overheating, it is usually because of airflow in and out. Your home’s ventilation system needs to be clear of dirt, dust, and debris. The more blockage in your ductwork and vents, the more friction is created, slowing down airflow and ultimately ending with an overworked furnace that continues to cycle on and off. And a blocked exhaust vent, such as a chimney or dedicated exhaust vent, can also cause a furnace to work harder. Check for things like leaves or bird’s nests.

The blockage may also be coming from a clogged furnace filter. You should clean or replace your furnace filter after a visual inspection reveals any type of build-up of dust or dirt. Do this at least every three-six months.

If you have a two-speed fan on your furnace, it is recommended that you run the fan in low speed during the cold months and high speed in the warm months. The reason? Warm air is lighter and takes less force to move.

There are other measures to take to prevent short cycling but these usually require a professional heating and cooling service technician to correct the problem. If in doubt, call your local heating and cooling contractor and schedule a furnace inspection. Don’t make your furnace work any harder than it was designed for – and keep your home’s occupants comfortable and safe.

How a Ceiling Fan Can Help Heat Your Bayview Home

Monday, December 19th, 2011

Most people in Bayview who have ceiling fans never turn them on in the winter. They assume that the fan is designed solely to cool the house – after all, blowing air feels pretty nice doesn’t it? But, a ceiling fan can actually help to move heat around your home and lower your heating bill if used properly. Here are some tips to do just that.

Rotating Warm Air

Warm air naturally rises. So, when you turn on your furnace and the blower fan pushes warm air through your ductwork into the various rooms of your home, the warm air immediately rises to the ceiling. So, for the room to feel as comfortable as you want it, you must wait for enough heat to circulate into the room to displace the cold air that was already there.

However, instead of waiting for warm air to fill the room, you can circulate the warm air as it arrives with a ceiling fan. By turning on your ceiling fan and changing the direction so it blows down (which most people already have it set to), the warm air will be pushed toward the floor, mixing it smoothly into the room and keeping you more comfortable without having the furnace on constantly.

This does two things. First, it keeps the room comfortable regardless of when the furnace cycles on or off. Second, it keeps the thermostat reading stable so the furnace doesn’t cycle on and off so quickly. If the warm air regularly rises up and the lower levels begin to cool, your furnace will frequently turn on and off as it tries to maintain the same temperature.

A Low Cost Addition to Your Home

Ceiling fans are inexpensive and aesthetically pleasing. They move air throughout the room, keep warmth low where you need it and can help reduce your energy bill in multiple ways. If you’re not sure whether a ceiling fan is right for you, talk to a technician about just how much money one of these simple devices can save you. I bet you’ll be convinced.

Greenacres Heating System Preventative Maintenance

Friday, December 16th, 2011

Ben Franklin once said, “An ounce of prevention is worth a pound of cure.” His famous quotation can apply to many things in life, including the heating system in your Greenacres home. While heating systems in Ben Franklin’s time consisted of wood burning stove and fireplaces requiring little maintenance, today’s sophisticated furnaces and building controls require a good dose of preventative maintenance in order to avoid mechanical failures and inefficient operation.

For example, a furnace runs better and lasts longer when you maintain a regular schedule of filter cleaning or replacing. A dirty or clogged filter can restrict airflow from the furnace into your home’s ventilation system and cause the furnace to work harder, putting more wear and tear on it and taking months, if not years, off of its useful life. If your furnace uses disposable filters, check them every month and replace them if necessary. If your furnace uses an electronic filter that requires cleaning, check it on a monthly or semi-monthly basis and clean it with soapy water and a hose. Be aware of the change of seasons which could add extra pollutants into the air like pollens, ragweed, and cottonwood. This debris easily finds its way into the filters and creates an unhealthy indoor environment.

You can also perform a simple visual inspection of working components inside your furnace by removing the access cover and checking – with a flashlight – for loose fan belts, frayed electrical wires, or a build-up of dirt and dust. Simple solutions include tightening or replacing belts, repairing wiring, and vacuuming out dirt and dust with a hose attachment. All of these actions will keep your furnace working better and prevent future failures.

You can also do a visual check of your home’s ventilation system, paying close attention to any cracks in duct seams or holes in flex ductwork. Using sealing cement or duct tape can usually fix these problems and allow for better, unrestricted air flow. Again, these actions will help your furnace work more efficiently and avoid premature failures.

Maybe the best advice for preventing heating system breakdowns is to have a regular maintenance schedule with a local qualified heating contractor. Most contractors can set you up with annual furnace and ventilation system inspections. Having a service agreement – as a rule – gives you priority emergency repairs and discounts on parts and services. Besides that, planned maintenance is also preventative maintenance, something that will give you peace of mind in the long run.

Question from Cocolalla: What Makes a Furnace High Efficiency?

Wednesday, December 14th, 2011

You’ve probably heard in Cocolalla about the new lines of high efficiency furnaces being released by popular home heating companies, but what exactly is different about these high efficiency devices from your current furnace? Let’s take a closer look at what a high efficiency furnace offers and why it can save you money.

Added Features

A high efficiency furnace uses familiar technology in a new way to reduce the amount of energy lost when combustion takes place. This means:

  • Sealed Combustion – Instead of open combustion which allows heat to escape during and after the combustion process, a high efficiency furnace uses a sealed chamber with carefully measured and fed airflow to burn fuel and produce heat. Exhaust heat can then be recaptured and used to heat air transferred to your air vents.
  • Two Stage Gas Valves – With a two stage gas valve, your furnace can respond to the temperature outside. There isn’t just one “on” switch. The furnace will regulate gas flow based on how much energy is needed to produce heat for your home. So, if there is a sudden burst of cold outside, the furnace will respond accordingly, but for most days when heating needs are low, it will use only the minimum amount of needed gas.
  • Programmable – High efficiency furnaces are now programmable, meaning you can set specific time limits for operation, change thermostat settings digitally and inspect the device through an electronic read out. The level of control given to you by a programmable high efficiency furnace can greatly reduce gas or electricity consumption.

Cost Benefit

The real reason many people are interested in high efficiency furnaces is that they are so much less expensive to operate. Instead of costing hundreds of dollars to run through the winter, they operate the bare minimum needed to heat your home. Using up to 95% of the fuel they consume to produce heat and regulating gas to cut how much is consumed during milder days, these furnaces are built to save you money.

If you have an old furnace that chews through energy like nobody’s business, now might be the time to consider the benefits of a brand new, high efficiency model.

A Question from Worley: What Does a Furnace Fan Limit Switch Do?

Friday, December 9th, 2011

When researching your Worley home’s furnace and potential problems it might have, you’ve probably run across a few references to the fan limit switch. And while you know that it can break in a number of ways, do you know what the switch does and what you should look for when checking your furnace its air handler for problems?

What the Limit Switch Does

To put it very simply, the furnace fan limit switch is a control that tells your furnace’s fan when to turn on and off. So, when the furnace isn’t on, it tells the blower not to operate (and send cold air into your home) and when the furnace is on, it tells the blower to turn on and start circulating the warm air.

While the primary function of the limit switch is to turn the blower fan on and off, it also has a safety role. When the temperature in the air supply plenum gets too hot, the limit switch turns off the furnace boiler to keep there from being any damage from overheating. This is handy if there is a blockage in the air vents or the controls are messed up due to water damage or improper adjustments to the settings.

Looking for Problems

Most of the time, when there is an issue with your furnace turning off or on frequently, the limit switch is one of the first things you will check. Because the switch is electronic and is attached to a thermostat which measures temperature in the air supply plenum, a small problem can result in it not working properly. So, you can easily check it by temporarily bypassing the switch and seeing if your device turns on or off properly.

In many cases, if the limit switch is the problem, you will still need to call a professional for replacement, but you can avoid a lot of headaches related to tracking down the source of the problem. If you suspect a limit switch problem, make sure to call someone immediately, because it does provide an important safety function and because without it your furnace won’t cycle on and off properly.

How Heating Zone Control Can Save You Money

Friday, December 2nd, 2011

The costs of heating your Rathdrum home have risen dramatically over the past couple of decades, thanks to higher energy costs and price increases for heating equipment. Despite the strides made in energy efficiency, there seems to be no end in sight for the steady rise in heating equipment operating costs.

Now add in the cost of heating unoccupied areas of your home, such as basements, hallways, or extra bedrooms, and the energy costs go even higher. Most of these costs are unnecessary and avoidable if you have the time and a small investment in a well-planned heating “strategy” for your home. This strategy involves using heating zone controls to make the most efficient use of your heating system.

In a nutshell, here is how heating zone control works. The rooms in your home are connected to your heating system by a series of ductwork, which carries heated and conditioned area to all corners. But some of these areas may not need to be heated as much – or possibly at all – compared to other rooms in your home. For example, do you need heat in your kitchen but not in your basement? Most people would answer yes. Or they may say they need more heat in the kitchen and some, but not very much heat in the basement.

Or try this: do most people in your house spend more time in one room, such as the family room, and less time in their bedrooms? If so, why would it be necessary to heat the bedrooms all of the time? In order to deliver heat to areas in your home that need it the most, the ductwork to these rooms should always be “open.” Ductwork to other unused areas of your home can be “closed” during various times of the day.

Opening and closing of ductwork and airflow is achieved by zone controls. A zone control is installed in the home which electronically or wirelessly opens and closes “dampers” in the ductwork, depending on the heating demand. You can divert heat to areas of your home using zone control and dampers while decreasing the heating load on your furnace. This type of heating zone control will move heated air to where you want it. Simply put, you are not heating areas of your home that don’t need the heat.

The heating zone controls can be programmed for various times of the day, too. For example, you may not need any heat in your basement while you sleep or when you are away from home. You can program the damper in your basement’s ductwork to remain closed or partially open during these times. In a sense, the heating zone control in your home acts like a programmable thermostat – only it uses a series of dampers to control indoor temperatures.

The next time you walk into an unused part of your home, think about how much money you are spending to heat it. It makes sense to consider heating zone controls. The initial costs of installing zone controls and dampers are minimal and the payback in energy savings and comfort are substantial.
