Heating Guide: Where to Place a Thermostat for Accurate Heating

Monday, December 26th, 2011

It’s easy to forget that with your furnace in the basement churning away all day to keep your Sumner home warm, but your thermostat is the single most important device in ensuring your home is heated to the temperature you want. If it stops working or it misreads the temperature inside your home, your furnace won’t know what temperature it actually is and will turn on and off at the wrong time.

Where Not to Place Your Thermostat

To avoid inaccurate readings, avoid placing your thermostat in the following locations:

  • Direct Sunlight – Direct sunlight will almost always increase the perceived temperature of the thermostat. Unless you live in a greenhouse, this will be very uncomfortable for everyone in your home.
  • Windows – Windows can result in direct sunlight and breezes. If the windows are not properly sealed, cold air can blow in and make it seem cooler in your home than it really is. In any of these cases, your thermostat will misread the indoor temperature.
  • Drafts – Drafts from improperly sealed doors, windows, or anything else in your home can negatively impact the thermostat.
  • Heat Vents – Don’t place your thermostat near a radiator or heat vent where it is likely to be warmer than anywhere else in the house.
  • Kitchens – Kitchens tend to be warmer than other rooms in the house, especially when in use. Avoid placing a thermostat here unless you have a zone control system and your kitchen is separate from other rooms.

A properly placed thermostat will ensure your home is heated or cooled to the temperature you desire regardless of outdoor conditions. If you’re unsure whether your thermostat is calibrated properly, check the temperature with a separate thermometer in a different location in the same room. If it is significantly warmer or cooler in one place than another, try to determine which is more indicative of the actual comfort level in your home. When properly located, your thermostat should never be an issue again.

Des Moines Heating Tip: What to Expect in a Low, Medium or High Efficiency Furnace

Wednesday, December 21st, 2011

When buying a new furnace in Des Moines, 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 for 10-20 years.

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 today.

Question from Eatonville: What is a Gas Furnace Draft Hood?

Friday, December 16th, 2011

As every Eatonville HVAC contractor knows, a draft hood is a necessary part of any gas burning appliance. For a gas furnace in particular it ensures steady air flow to the burners to avoid flares or the pilot light being put out by fluctuation in temperature and air flow.

What the Draft Hood Does

The draft will change in the chimney as exhaust vents towards it – especially when going from cold air to hot. A draft hood is placed above the upper most part of the gas furnace to draw air into the chimney and makes it possible to draw more or less air through the chimney as necessary to create a constant flow.

This makes it possible for the burner to enjoy consistent air flow without any wind gusts or sudden temperature spikes or drops. Hot air, if not put through a draft hood would create a strong air flow through the burners.

A draft hood cools the air as it is released by the burners from 500 degrees F to between 300 degrees F and 350 degrees F. The cooling needs to be carefully calibrated to avoid condensation build up in the chimney however – a problem that occurs when the temperature gets too low.

Maintaining Pressure

The draft hood is a part of a larger system designed to maintain air flow to the chimney. For every cubic foot of gas burned, the furnace needs to have 15 cubic feet of air for combustion and another 15 cubic feet of air for dilution. A draft hood and the rest of the ventilation system make it possible to put a furnace that has many thousands of BTUs in the basement of your home and still supply it with enough air to burn gas and dilute the exhaust before it enters the chimney.

For all of these reasons, if you see your pilot light flickering irregularly, notice a backflow of exhaust or a burning smell in your furnace room, it’s important to call a professional who can inspect and repair the problem before it becomes any worse. Not only can gas burner exhaust contain high levels of carbon monoxide, it can be bad for the device and the chimney if it doesn’t vent properly.

What to Look For in an Olympia HVAC Contractor

Friday, December 9th, 2011

Here are some things to look for when bidding out a service/replacement job or a new installation in Olympia. The contractor you hire should answer yes to most of these questions (except the obvious). The bad contractor, who is likely the lowball bidder, will probably not.

  • Can the bidders give you references from former customers and show details of work they have done?
  • Can the bidders verify if they are licensed to do their work or have any certifications?
  • Do the bidders include the cost of pulling permits and paying for inspections for their work?
  • Are the bidders members of any professional organizations and can they show credentials?
  • Do the bidders belong to any local Chambers or other civic organizations?
  • Do the bidders offer an option of products and services to choose from, rather than just one choice they say “is best for you?”
  • Do the bidders take measurements and do mathematical equations to determine what size equipment you need (called load calculations or heat loss/heat gain measurements to determine the proper sized furnace or air conditioner, for example).
  • Do the bidders constantly criticize their competition and use this tactic more than explaining what they can do for you?
  • Do the bidders listen and ask questions?
  • Do the bidders use pressure tactics like offering add-on equipment for a “special price” or say, “I will need to know you answer as I have other customers who need my services right away.”
  • Do the bidders offer a variety of warranty plans to back up their work?
  • Do the bidders require a large deposit or all of the money up front?
  • Do the bidders have a neat appearance, i.e. well-groomed and clean clothes?
  • Are the bidders’ vehicles clean and free from obvious rust or body damage?

There are likely several other considerations but the point is, the HVAC contractor should be professional and businesslike. They should “act like they’ve done this before.” The low bidders may appear to put on a good face, but dig below the surface and ask a lot of questions. The low bidders may quickly lose their happy disposition.

How Often Should I Replace My Furnace Filter? A Question from Tukwila

Wednesday, November 30th, 2011

Just like the filter in your air conditioner, replacing your furnace filter is the key to keeping your Tukwila home healthy and comfortable. By keeping a good filter replacement schedule, you will reduce wear and tear to the furnace and keep your home warm, while keeping your family healthy and controlling energy costs all winter.

But when does your furnace filter need to be changed? Well, each system is different, but there are some general guidelines and recommendations to follow that can help you keep it all straight and stay on top of your furnace filter situation.

Conventional Wisdom

The long-standing rule of thumb on furnace filters is to change them every month. This is good practice if you are using older fiberglass filters, but for newer, more efficient filters, you should do it a little differently. These should be inspected and cleaned at least once a month, but you may need to replace them that frequently also.

Sometimes it is a little more complicated than these general guidelines, so it pays to be aware of some factors and conditions in your home that may affect how frequently you need to change your filter.

Things to Consider

As mentioned above, the first thing to consider is the efficiency of the filter. Because new filters are so efficient, when they get dirty or clogged with dust and debris, they actually restrict airflow, making your furnace bog down and work harder. So, it is important to stay on top of a monthly inspection and cleaning schedule with these filters.

Also take into account air quality and sources of allergens both inside and outside your home. If you live in an area with a lot of pollutants in the air, you’ll want to replace your filters often to keep those out of your home. If you own a lot of pets, the dander and hair will wind up in your furnace filter and you may have to replace it more often.

Complicated enough for you? It doesn’t have to be. Simplify the whole process by doing the following: check your filter monthly and be prepared to change it that often, clean high-efficiency filters regularly, replace the filter at least every three months and again at the start of heating season.

If you do those things at a minimum, you will be in pretty good shape.

Why is My Furnace Turning On and Off? A Question from Seatac

Wednesday, November 23rd, 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 Seatac 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  heating and cooling service technician to correct the problem. If in doubt, call your local qualified 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 Much Maintenance Do Solar Panels Require? A Question from Des Moines

Friday, November 18th, 2011

The most commonly cited benefits of solar panels are that they are eco-friendly and cost effective. Many resources on the subject are quick to point out that despite high upfront costs, solar panels pay for themselves over time by being durable enough to provide cheap energy for a long time. You know all this, but as a Des Moines homeowner, you also need to know what kind of maintenance is involved in a solar system. In short, after investing your cash, how much work will you put in?

The amount of maintenance required by solar panels is fairly low, as they are quite durable and the only truly vulnerable component is the glass face. There are some steps that you can take to maintain and extend the life of your solar system, though. Below are some routine maintenance tips.

Cleaning

There are quite a few things you can do to keep your solar panels in tip top shape. For example, you should clean your solar panels regularly with water and dish soap to remove any surface grime. There are also surface sprayers available which allow you to clean your panels effectively from the ground.

You should avoid installing panels in a location where they will attract dust, grime and bird droppings, such as near trees, branches, or other growth. Remember that your solar panels are only as good as the energy they can capture, so keeping them clean is much more than a simple cosmetic measure.

Inspecting

To ensure they continue to work properly, you should examine your solar panels regularly according to the manufacturer’s instructions. Clean away any dirt or debris and tighten any loose connections. Should your panel become damaged in any way, for example by severe weather or blown down branches, have it repaired immediately.

If your system has a backup battery, be sure to replace the batteries as they wear down. There will be a noticeable decline in performance when this happens. Also inspect the connections on both the batteries and the inverter to ensure they are tight.

Generally speaking, solar panels themselves don’t require much maintenance. Simply keep them clean and inspect them regularly and they should last a good long while. Other components, such as backup batteries or generators, inverters, and additional arrays will require extra maintenance as well. For the most part, installing a solar system will not add much to your usual household maintenance tasks.

Essential Components of a Home Comfort System: A Tip from Federal Way

Wednesday, October 19th, 2011

Indoor comfort in your Federal Way home 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 for the building occupants.

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.

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.

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

Warning Signs of a Broken Furnace: A Guide From Renton

Wednesday, October 12th, 2011

How do you know when your furnace in your Renton house is “on the fritz?” There are warning signs of a broken furnace and some are recognizable – but not all. A broken furnace not only deprives your home of heat and comfort, it also can be deadly, too.

Let’s look at some of the warning signs.

Each year, hundreds of people die and many more are injured from the most common household poison: carbon monoxide. This colorless and odorless poisonous gas comes from several sources and the furnace is the most common source of all; more precisely a broken or malfunctioning furnace. Carbon monoxide is a result of incomplete combustion of a fossil fuel, which is when a fuel does not burn correctly or completely. In a furnace, carbon monoxide gas comes from a poorly operating burner or a cracked heat exchanger. A properly tuned and maintained furnace greatly reduces the risk of carbon monoxide poisoning.

Since carbon monoxide gas is colorless and odorless, it can go undetected. It can make people sleepy and create flu-like symptoms. Sometimes a person may fall asleep and never wake up. But there are warning signs. Drowsiness, vomiting, or flu-like symptoms are a warning sign. Regularly scheduled maintenance of your furnace by a qualified heating and cooling professional and installation of carbon monoxide detectors can reduce the risk of falling ill to carbon monoxide gas.

Another warning sign is a higher energy bill. Sometimes you can’t detect a problem right away because, like carbon monoxide, there may be no obvious signs. Higher utility bills can be a sure sign of a furnace that is working too hard and running more than usual. This may be a result of clogged or dirty air vents, or dirty filters. If your monthly bills are higher than those of the previous year, it may not just be because gas prices are higher.

There are other warning signs of a broken furnace, too. The most obvious is the failure of your furnace to bring your home up to the desired thermostat settings or to maintain an even temperature. Cold or uncomfortable houses are sure signs of a broken furnace. The furnace may cycle on or off, causing an uneven or inconsistent flow of heated air. This can be because of a poor blower or a clogged furnace filter. If you don’t feel any moving heated air or detect any unusual odors or smells coming from your heating vents, that’s a sure sign of a broken or malfunctioning furnace.

A broken or cracked gas line can emit odors and can cause a furnace to malfunction, too.

Don’t take a chance of losing heat and comfort this winter. At the first possible warning sign, call your local heating and professional for a heating system tune-up.
