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.

Is Your Kent Home More Valuable with Energy Efficient Appliances?

Monday, November 28th, 2011

It’s impressive the things people do to improve the value of their Kent home. We’re talking about crown molding, new floors, new siding, upgrades to the landscaping and much more. The cost of upgrading these things can grow out of hand quickly and if the boost to your home’s value isn’t equally exponential, it’s hard to justify the expense.

So, it’s always nice to find a simple upgrade that can be performed for a few hundred dollars that will save you money immediately and improve the value of your home in the future. Your appliances are one such upgrade.

The Value of Energy Efficiency

An energy efficient washing machine can save upwards of $150 per year on water costs. An energy efficient toilet cuts consumption by as much as 150%. Low flow shower heads cut water costs by one third to one half and your heating and air conditioning systems can be improved by 10-35% depending on the upgrades available to you.

When you add up all those savings, the result is a tremendous amount of money that can be saved each year on everything from your water bill to your cooling needs. Imagine what happens when someone looks to buy your home. They see that there are all new appliances with energy efficient ratings that will save them money.

It’s not just lower bills; it’s a decrease in upfront investment. On the surface, it’s unlikely that your energy efficient appliances will directly increase the value of your home, but they can increase the likelihood of someone paying what you’re asking for the home. They add value to the livability of the home, if not the property itself and in today’s housing market, that’s a major plus.

Best Upgrades

The best upgrades to your home’s appliances are the ones that save money without additional work. Water saving appliances should top your list since they are used throughout the year. A new toilet, a new washing machine, a new shower head and sink faucets all designed to cut down on water use are valuable upgrades. Major upgrades to your heating and cooling are good if you need an upgrade anyway or you plan on staying in your home for a few years.

What Happens if My Heat Pump Loses Power? A Question from Edgewood

Monday, November 7th, 2011

One of the advantages of having a heat pump in your Edgewood home is that they operate on electricity, so you don’t need to worry about having maintaining a supply of fuel to keep yours running. Where a furnace or boiler might call for you to purchase supplies of oil or natural gas, and a wood stove means keeping potentially messy firewood around, a heat pump runs cleanly on electricity.

Heat pumps are good at using electricity, too. They are often able to produce heat energy that can be as much as three times the electricity they draw to produce it. This means not just convenience, but also a big savings, just by virtue of using electrical power.

The risk there, of course, is that if and when the power goes out, so does the heat pump. That means when a big winter storm drops a tree on the local power line, things can get cold inside mighty quickly. For these situations, you should have a backup heating solution on hand to keep everyone comfortable in the short term. And, as a responsible homeowner, you likely already have this taken care of.

But what happens when the power comes back on? Can you just fire your heat pump right back up without missing a beat?

The short answer is “no.” You should not do that, for at least two reasons. First of all, after any power outage, you should always take care to turn on appliances gradually over a period of time rather than all at once in order to avoid a spike in demand at the power company, which can blow a grid. That’s just a general tip.

Specific to heat pumps, though, there is a unique concern. If the heat pump loses power for more than 30 minutes, the refrigerant can get too cold to flow properly, so turning it right back on can cause the whole thing to conk right out. Instead, do the following:

  1. Make sure the heat pump is off. You can do this during the power outage.
  2. Once power comes back on, turn the heat pump to the “Emergency Heat” setting. This will allow the compressor to warm up slowly and get the refrigerant warm enough to start flow freely again.
  3. Wait. The time you need to wait varies depending on the size and manufacturer of your heat pump, so refer to the manual. In general, you should wait at least 6 hours.

After this process, your heat pump should be ready to resume normal operation without issue.

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.

Benefits of Replacing Your Furnace in Fife

Monday, October 17th, 2011

You are about to make one of the largest purchases in your life – a new furnace for your Fife home. Maybe your old furnace is on life support and needs immediate replacement or you are looking for a better, more efficient furnace that will raise the comfort level of your home while reducing utility bills and carbon emissions.

If the furnace in your basement, crawl space, or attic is 15-20 years old, it may be a single-stage 80% percent efficient model, which doesn’t meet the higher efficiency standards of today’s models. It uses more energy, i.e. gas, oil, or electricity, to operate. And a single-stage furnace does not always provide even heating to all rooms in the home, based on the varying winter weather conditions. There may be large temperature variations from room to room.

Your new furnace will likely be more efficient and environmentally friendly than the one it is replacing – which are the two biggest benefits to replacing an old furnace. So, let’s take a closer look at these benefits, which link energy efficiency to the latest technology – namely two-stage furnaces and variable speed motors.

Two-stage furnaces start out by running in a first stage, which uses less than 70% of its capacity. This stage works well on moderate winter days. On colder days, the furnace will meet your extra heating demand by adjusting to the second stage in the heating cycle. Since the furnace spends most of its time operating in its lower capacity (first or single stage), it burns less fuel than a traditional furnace that always runs at full capacity and then shuts off when heating demand is met. You will see lower utility bills and a shorter payback period on your new furnace investment.

Variable-speed motors can actually save you money on your energy bill as they consume less electricity than standard motors. Variable speed furnaces save you money by having a higher SEER rating. SEER is the abbreviation for seasonal energy efficiency ratio. The higher the SEER, the more energy efficient the unit. The low operating costs of a variable speed furnace can allow you to run your furnace blower. With the low operating costs of the variable-speed furnace you can constantly run your blower without the worry of driving up your utility bill, allowing for continuously filtered air.

The U.S. government, as well as local governments are making it more tempting for homeowners like you to purchase new energy efficient furnaces, too. Government agencies have been offering tax credits to homeowners who switch to energy-efficient appliances, including heating and cooling products. Utility companies also offer rebates to homeowners who wish to lower their utility bills by using high-efficient appliances. Chances are, your local utility has some type of rebate program in place.

And when you shop for a new furnace, look for add-on equipment such as electronic air filters and programmable thermostats. Each will raise the comfort level you will be enjoying from your new furnace.

What to Do if Your Heating System Breaks in Tacoma

Friday, October 14th, 2011

What if the heart of your Tacoma home’s heating system – the furnace – stops working? The warm air that used to flow from your vents has been replaced by a chilly draft. It isn’t time to panic, but it is time to take action. Before you do anything, determine why the furnace stopped working. It may be something as simple as a tripped circuit breaker in your electrical panel. Check the circuit breakers first.

The pilot light in your furnace may have blown out. It can be re-lit if you follow the directions in your furnace owner’s manual. You can find answers on how to re-light a pilot light on the Internet, too.

If the shutdown has not been caused by an electrical or pilot light failure, there is still no need to panic. But another obvious question is: did you pay your last gas bill? Maybe you had a shutoff notice and either ignored it or forgot about it.

Now that you are convinced that the furnace has pooped out, here are some things you should do. First, find the name of a qualified heating and cooling professional. If you already use a heating contractor, contact them and schedule a service call.

While you are waiting for help to arrive, ensure that everyone is safe and accounted for. Make sure pets are nearby and protected from the cold, too. What you don’t want to do is use any appliance to keep you warm that is not designed to keep you warm, like a stove. If you have electric space heaters or propane heaters, carefully locate them in a well vented room (windows open a bit or portable fans circulating air). You don’t want any build-up of gases from fossil burning appliances, gases which could contain deadly carbon monoxide.

Huddle up everyone into a room and break out lots of blankets. You may even want to make an “adventure” of this – find a movie to watch and pop up a bunch of popcorn.  If your waiting time is more than 24 hours, you might want to call up a friend or relative and make arrangements to spend the night with them.

The main thing to remember is not to panic. Most qualified heating contractors, knowing the circumstances, will send out a repair person in a matter of minutes or within one or two hours. Just remember to avoid keeping warm by using unvented heating devices.

How Heating Zone Control Can Save You Money: Some Advice from Covington

Monday, October 10th, 2011

The costs of heating your Covington 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.
