Uxbridge Heating Guide: Hydronic Heating vs. Forced Air Heating

Monday, February 4th, 2013

At Advantage Airtech Heating & Air Conditioning, we know that there is not any one heating system that is inherently superior to any other. All home heating systems have pros and cons specific to themselves. When it comes to choosing a new heating system for your Uxbridge home, though there is certainly an option that is best for you, your home and your personal heating habits. Let Advantage Airtech Heating & Air Conditioning help you find the heating system most appropriate for you situation. Here are some highlights and drawbacks of two popular home heating methods: hydronic and forced air heating systems.

Forced air heating systems are extremely popular, and for good reason. With a proper installation, maintenance and repair services a forced air heating system using a furnace can be extremely efficient and effective, providing your home with even, comfortable heating. Many forced air systems suffer some heating inefficiency, though, and the cause of this inefficiency is often traced back to the air ducts. A forced air system depends on ductwork to distribute conditioned air throughout your home. If these air ducts are torn, damaged, improperly installed or otherwise compromised then you may wind paying more than you should due to energy loss.

A hydronic heating system does not suffer this sort of energy loss. Hydronic systems circulated heated liquid via a piping system throughout your home. This type of system depends on radiant heat, in which objects are directly heated by the pipes containing the heating fluid. This heat is then transferred radiantly to people and objects in the room. Whether your hydronic heating system operates this way or with baseboards and radiators, though, the installation of this type of system can be problematic. It is best completed during the construction of a home or building. While it can certainly be incorporated into existing homes it can be intrusive and is best scheduled during remodeling.

For more information about hydronic, forced air or any other heating system just call Advantage Airtech. We are always happy to share our expertise with consumers in the Uxbridge area. Let us know what we can do for you to make your home a more comfortable place to live.

Newcastle Heating Repair Question: Why is My Furnace Making Noise?

Monday, April 9th, 2012

During a bitterly cold winter, in the luxury of our homes, we have the ability to adjust the temperatures to comfortably walk barefoot down the hall.  It is easy to take our furnaces for granted, but without proper maintenance, they can become noisy and irritable, growling with mysterious sounds of dissatisfaction and ominous groans, warning that slippers and more blankets may soon be necessary.

This does not have to happen to you.

At the beginning of each season, it makes good sense to care for the furnace that is going to take care of you.   Scheduling an annual inspection and filter change with Advantage Airtech Heating & Air Conditioning ensures a longer life and more comfort.

Rattles and Bumps in the Night

At the first sound of trouble, checking the filter can often be a quick relief.  As air passes through the furnace, a filter picks out much of the dust and some heavier particles that have come along, gotten snagged and accumulated over time to create a solid blockage.

This filter can become clogged and force the furnace to work much harder to push the air through the blocked passage. Located just inside the front panel of the furnace, the filter is very accessible and easily exchanged for a clean one.  This should be the very minimum of regular maintenance and is simple enough to do that it can make anyone feel handy.

Deeper Trouble

Heated air and cold air returning to and from the furnace travel through ductwork which is often metal (those long, silvery boxes tucked up between joists in your basement and covered by a nasty layer of cobwebs).  The vibration of footsteps across the floor overhead or even of just the air movement through the ducts can loosen the fasteners and rattle the metal like a rumble of thunder.

Internally, there are fans and lots of moving parts in the motor.  A noise coming from this area portends a repair of a more complicated nature and should have the inspection of a certified Newcastle HVAC technician, a service easily provided by Advantage Airtech Heating & Air Conditioning.

With proper care and maintenance, furnaces are built to last for decades, providing heat and comfort to the home or office and improving the quality of life for the people inside.  Consult with experts to ensure the efficient operation.

Goodwood Heating Installation Tip: Pros and Cons of Various Heating Systems

Monday, January 9th, 2012

When it comes time to install a new heating system in your Goodwood home, there are a lot of options to consider. Many people get overwhelmed when confronted with all of the furnaces, boilers and heat pumps on the market these days. So, to help you get a handle on what each has to offer and which will offer you the best benefits, here is an overview of the modern heating system market.

Furnaces

Furnaces are the core of a forced air heating system and use gas, oil or electricity to heat air which is then circulated through your home by a blower in your air handler. Furnaces are among the most fuel efficient heating systems on the market today with options available at up to 95% AFUE (meaning it uses up to 95% of the fuel consumed to produce heat). They are also inexpensive to install and while they don’t last quite as long as boilers, they are highly efficient when well cared for.

Boilers

Boilers use gas, oil or electricity to heat water or steam which is then circulated through your home into radiators or baseboard heaters. The heated water or steam releases heat into your home and heats it in turn. While not quite as energy efficient as a high efficiency furnace, boiler heat is perfect for homes with existing radiators and no room for vents and ductwork. It also has less of an impact on indoor air quality since there is no air movement and boilers tend to last a very long time when well maintained.

Heat Pumps

Heat pumps are becoming increasingly popular, especially in milder climates where it rarely gets below 40 degrees F. A heat pump uses the same technology as an air conditioner to extract heat from outside using a compressor, evaporator coils, and condenser coils with refrigerant.

It is most efficient in the spring and fall when temperatures are mild, but it uses much less energy than either a boiler or furnace and it can be used in the summer to cool your home. When properly maintained, a heat pump will last 10-20 years and save quite a bit of money, though it is recommended that you have an emergency heat source for days when the temperature outside gets below 40 degrees F.

Durham Region Heating Guide: What Is a Downflow vs. an Upflow Furnace?

Friday, January 6th, 2012

When you go looking to buy a furnace in Durham Region, you may well be surprised by how many different elements go into making a good purchasing decision. There are simply so many different kinds of furnaces available now and they each are more appropriate for certain situations. That means that finding the one that’s right for you is less about finding the one best unit than it is about finding the one that is the best match for your particular circumstances.

This applies to the type of fuel the furnace uses, its energy efficiency, and whether it’s an upflow furnace or a downflow furnace. Energy efficiency and fuel types are probably things that you’re more or less familiar with. But what are we talking about when we classify a furnace as an upflow or downflow model?

Well, it’s pretty much what it sounds like. These terms refer to the direction the air flows as it is taken in and heated by the furnace. So in an upflow furnace, the cool air is taken in at the bottom, warmed, and then expelled at the top. A downflow furnace, on the other hand, takes in cool air at the top and expels heated air at the bottom.

While this is all very exciting, it may still not be obvious what impact this will have on your decision about what type of furnace to buy. The main thing you’ll have to think about when you’re deciding between an upflow and a downflow furnace is where the furnace will be placed in your Durham Region house.

An upflow furnace is generally installed in the basement so that the heated air is directed towards the parts of the house you want cooled and so that the furnace can be appropriately vented outside of the house. On the other hand, a downflow furnace would be installed in your attic for the same reasons.

So where you want to have the furnace installed is probably the biggest thing to take into account as you’re comparing these two types of equipment. Of course, whether you pick an upflow or a downflow furnace, you’ll still have to select the appropriate AFUE, size and fuel source to best meet your needs. But making the choice between upflow and downflow can at least make it easier to narrow down your options. If you need help choosing the right system, talk to your heating and air conditioning professional.

Question from Uxbridge: Why Does My Furnace’s Pilot Light Keep Going Off?

Wednesday, January 4th, 2012

If you have an older furnace with a gas pilot light and it keeps going out, heating your Uxbridge home can become a frustrating process. Not only are you forced to trudge downstairs to light it every time you need heat, but you’re probably starting to worry that there is something wrong – either with your furnace or with your gas supply. Here are some possible reasons for your pilot light shutting off and what you can do about them.

  • Thermocouple – The thermocouple is used to generate electricity from the gas being burned by the pilot light to power the sensor that keeps the pilot light running. So, if the thermocouple goes bad or gets blocked in some way, the sensor won’t work properly and your pilot light won’t remain lit. Even a small problem with the thermocouple can lead to the valve closing and the pilot light going out.
  • Gas Pressure – If the gas pressure going to your furnace is too low, due to a leak, pipe problem or another appliance, the pilot light may not have enough gas to stay lit. While it is possible that the problem is not related to gas pressure, anything that affects the flow of gas into your home should be inspected by a professional. If you smell gas, leave the house and call your gas company immediately.
  • Mercury Sensor – The sensor in your pilot light that maintains the flow of gas to keep it lit can go bad. Keep in mind that these sensors almost always used to contain mercury (and often still do), so you should be careful with them. It’s best to call an Uxbridge professional who can replace and dispose of it properly.
  • Dirty Burners – Excess dust, lint, rust or sulfur build up can result in blockage of the burner holes. When this happens, gas will flood into the chamber but not light right away. When it does finally light, it will create a small boom or banging sound that will often put out the pilot light. Not only is this inconvenient, it is very dangerous. Fortunately, it can be avoided with annual cleanings of your furnace.

The best way to keep your pilot light lit at all times is to have someone inspect it once a year. If something happens in between, you can usually rule out cleanliness issues and call in a professional to check the thermocouple and sensor.

Furnace vs. Heat Pump: A Tip from a Markham Heating Contractor

Friday, December 16th, 2011

If you’re preparing to replace your existing heating system, you may very well be struggling with the question of whether to go with a furnace or a heat pump for all of your Markham home’s heating needs. Each of these systems have their own advantages and drawbacks, and once you’ve narrowed it down to one type or the other, you’ll still have a pretty wide variety of products to choose from.

Furnaces are still the most popular type of home heating equipment on the market. You can get furnaces that run on gas, oil or electricity, although gas furnaces are by far the most common type of furnace around these days. The latest models are extremely energy efficient, with AFUE ratings reaching into the high 90%s.

Like heat pumps, furnaces use ducts to transfer heated air throughout your home. They typically require regular maintenance once every year or two depending on the type of furnace you have, and they can be expected to last anywhere from 15 to 25 years when properly maintained. Most modern furnaces are also made to be compatible with a central air conditioning or cooling system as well.

Heat pumps, on the other hand, don’t generate the heat that they circulate throughout your house. Instead they are able to extract the heat from the air outside and pump it inside. This means that they use much less energy than even the most energy efficient furnaces.

However, heat pumps are only capable of heating your house comfortably when the outside temperature is above freezing. If you live in an area with particularly long and frigid winters, you’ll probably find that you need to supplement your heat pump with another heat source. Because of this, it actually makes little sense to use a heat pump in more extreme climates.

On the other hand, if you live in an area with relatively mild winters, heat pumps can be a great option. They provide a constant flow of warm air to all parts of your home and can also keep you house cool during hot summer months. To cool your home, heat pumps simply reverse the process they use to warm it. They take the heat out of your indoor air and pump it outside. This is a very effective home cooling method and makes heat pumps a great solution for year round comfort.

Enniskillen Heating Contractor Tip: How a Furnace Works

Monday, December 12th, 2011

Do you know how your furnace works? Believe it or not, lots of Enniskillen homeowners probably can’t explain the operation of furnace. It probably isn’t at the top of your “to do” list. It’s only important to know that once you set your thermostat to a desired temperature, the furnace comes on and warms the house.

Let’s look at how a gas furnace works since natural gas is found in most U.S. households. Gas furnaces use natural gas or propane to provide energy used for generating heat.

When the temperature in your home falls below the level set on the thermostat, an electric pilot light automatically ignites to heat a burner inside the furnace. This burner uses gas to generate heat within a combustion chamber inside the furnace. After the furnace senses that the thermostat has triggered the flame and that it is properly lit, the actual spark (or ignitor) is turned off.

Simultaneously, a motor in the furnace pulls in air from an exchange or return, which could be a grill in the floor, ceiling, or wall of a house. That air flows through ducts into the plenum of the furnace. The plenum is on the opposite side of the heat exchanger from the burner.

Gas will typically burn for at least two minutes before the blower starts to disperse heat throughout your home. This extra time gives the air an adequate period of time to warm up and also so that cold air won’t be pushed through the vents into the rooms in your house at the start. After either the preset time (roughly two minutes) or pre-established temperature is reached, the blower’s motor is turned on and it blows air over the heat exchanger, which usually consists of a series of copper tubes or pipes. When a fan blows air onto the heat exchanger, the air is heated. This heated air is then blown through a series of ducts to heat your home via vents in the floor, walls or ceiling. Exhaust fumes from the combustion process exit the furnace through a gas flue or chimney.

Just as the heat in your home turns on when a certain temperature is reached, it also turns off after the rooms are warm enough, thanks to your thermostat. The thermostat again senses the temperature in the room. When the room warms up to the temperature set by you at the thermostat, the gas valve is switched off, stopping the flow of gas. After the gas is turned off, the blower motor will still run for a few minutes, allowing the heat exchanger to cool off a bit. In some furnaces, the blower motor never shuts off, but operates at low speed to keep air circulating throughout your home.

In a nutshell, your thermostat is the brain in your heating system and your furnace is the brawn, doing most of the work.

How Warm is Furnace Heated Air? A Question from Oshawa

Friday, December 9th, 2011

When your furnace turns on every day and warms your Oshawa home, just how hot is the air being blown through your vents? It’s a common question and while it varies depending on the type of furnace you have and the length of your ductwork, normally, the air is about the same temperature in most homes.

The Heating Process

When you turn on your furnace, it ignites fuel (gas or oil) or heats elements (electricity). A blower fan blows air through the heat exchanger and then into ductwork that distributes the heated air to vents around your home. When the combustion occurs and air is first heated, the temperature is between 140 degrees F and 170 degrees F.

This is extremely warm and could be dangerous to anyone if they got too close to it or it was blown directly into your home. However, as the heated air is distributed into your home it starts to cool. In some cases, it loses a significant amount of its energy in the ductwork.

This is intended, of course, because the temperature would be much too high if it was distributed directly to your rooms. That’s why high velocity ductwork often requires regulation to avoid overheating of the air. Cooling like this is normal and results in a better, more evenly distributed airflow.

When Something’s Wrong

To know something is wrong with your heating system, you must first understand what temperature air normally is when distributed through the vents. This will vary depending on which room you are in and how big your home (and furnace) are. However, if you notice a sharp drop off in comfort level in your home, it takes longer to heat rooms when cold or if that heating is suddenly uneven, it may be time for someone to inspect your furnace and check for potential problems.

A technician will then check to see if the air is being heated to the target 140-170 degrees F or if heat is being lost in the air handler or ductwork. There are a number of issues that can contribute to lost heat in your heating system – the easiest way to be sure the problem is solved properly is to call a professional when you notice the problem.

AFUE Ratings: A Tip from Ajax

Friday, October 28th, 2011

Happy Halloween weekend from everyone at Advantage Airtech! We hope you have a fantastically spooky time! And because it is starting to get cold out there, here is some information about AFUE ratings to help you keep your house warm for after trick or treating.

If you’ve been shopping for a furnace in Ajax, chances are you’ve noticed that each furnace has its own annual fuel utilization efficiency (AFUE) rating. These generally range from 80% to the high 90% s and the higher the number, the more fuel efficient that particular furnace is.

But what does this number really mean and just how much should you care? Well, the AFUE rating should actually have a significant impact on your furnace purchasing decision, but that doesn’t mean that you’ll always choose the furnace with the highest efficiency rating either.

For one thing, you’ll have to recognize that not every type of furnace is capable of running at the highest efficiency levels. Oil furnaces, for instance, can’t compete with the super high efficiency gas furnaces on the market today. That’s not to say that an oil furnace might not be the best choice for you under certain circumstances, but it does mean that you should take a close look at your furnace usage before you make a decision.

If you do choose a gas furnace, you will of course have the option of getting one that can reach up to 97% or so efficiency. However, that may not always be the best choice either. If you live in a place where with very harsh, long winters and you’re going to be using your furnace heavily, then it’s definitely worth investing in a higher AFUE furnace that can save you considerable amounts on your monthly heating bills.

But if you don’t use your furnace too often as your area has more mild winters it’s probably not worth it for you to invest in such a high efficiency product. That’s because the higher the AFUE of the furnace, the more expensive it is to purchase and install. Certainly you’ll save money every month because you’ll be getting more heat out of the fuel you’re paying for. But if you don’t use your furnace all that much, the savings really won’t be that substantial.

Don’t forget that a furnace with an 80% AFUE rating is still quite energy efficient.

Hydronic vs. Forced Air System: Some Pointers from Clarington

Friday, October 21st, 2011

Both hydronic and forced air heating systems can serve you well depending on the specifics of your Clarington home and your household heating needs. Certainly each of these types of home heating systems has advantages and drawbacks, but there is really no clear cut answer about which is better. All you’ll be able to determine is which one is best for you.

While current discussions about hydronics have come to focus on the applications for in floor radiant heating, this category of heating systems is actually much broader than that. Really, all the term hydronics means is that the system uses water to carry the heat throughout the house instead of air. This is what traditional radiators always did, and these types of systems are certainly still perfectly appropriate for certain types of homes.

Particularly if your home doesn’t already have ductwork installed, hydronic heating might be the best option for you because it doesn’t require ducts to get the job done. All you’ll need to have installed are pipes to carry the water to different parts of the house. These pipes are much easier than ducts to install and take up much less space overall.

If you’d like to include radiant floor heating as part of this system you’re certainly able to. However, using only this type of heating to heat your entire house is not particularly efficient or practical. Radiant flooring is particularly useful in basements because no matter how warm the air in the room is, the floor in these areas will still be cold.

However, if you do already have ducts installed in your home, it may make perfect sense for you to have a forced air heating system installed. While there are sometimes problems with the evenness of the heating experience that you get with these types of heating systems, proper installation of a high quality system can usually mitigate those types of issues.

Forced air heating systems are also convenient because they are made to work in concert with many types of central air conditioning systems. If you have hydronic heating and think you’d like to have a central air conditioning system as well, you’ll either have to install multiple window or wall units or have ducts put in anyway.
