Cool spots are an unfortunate side effect of modern air conditioning technology. They occur when HVAC systems are improperly sized or ductwork is improperly installed. Other factors like insulation, vent configuration or window placement can also contribute to the presence of a cool spot (and possibly some hot spots). So, what can you do about it? There are a few options, starting with a quick inspection of the space.

Checking for Common Problems

Your HVAC contractor will check a number of things. Most importantly, they’ll measure the size of your HVAC system and compare it to the dimensions and particulars of your house. Usually, in the case of cool spots, the problem is directly related to an oversized system. When it turns on, even for a few minutes, it produces more cold air than is necessary, flooding your home with cooling. The thermostat recognizes this and the system shuts off soon after turning on. As a result, you’ll feel fluctuation between cold and warm as the system fails to properly condition the space.

Modern systems are sized for your house at 100% capacity. So, when the system turns on, it should stay on for a substantial period of time, keeping your home cool. Turning off and on frequently is bad for the system and wastes energy (plus it produces those pesky cool spots). Keep in mind that hot spots can also occur if the system isn’t powerful enough.

Your HVAC contractor will also look for vent placement and duct configuration. Improper placement of vents can lead to pooling of cool air that creates cool spots. By checking for potential problems in the layout of your HVAC system, your contractor can determine if new vents or ducts are needed to solve the problem.

Fixing the Cool Spots

For now, you may just want to move to another part of the house. Cool spots rarely affect the entire space – they tend to cluster around vents and outlets and can usually be fixed by resizing or adjusting your system. However, only your Oshawa air conditioning contractor can tell you for sure what the best solution will be for your air conditioning issues so make sure to schedule an inspection.

• SEER Matters – What is this magical acronym you hear so much? SEER refers to how many BTUs your air conditioner can produce with a single watt of electricity. A low SEER device therefore uses a LOT more electricity to produce the same volume of cooling as a high SEER device. Since current devices offer SEER of 13 or higher (some are up to 20+), just about any upgrade will save you money relatively quickly if your current air conditioner has a rating of 8 or lower.
• Program Your AC – If you have a single point analog thermostat, you’re wasting a LOT of electricity. You’re either paying to cool your house while it’s empty or you’re coming home to a roasting hot living space. Purchase a programmable unit and set the system to 85 degrees when you’re not home. With timers in most digital units, you can tell it when you’ll be home so that you walk into a cool, comfortable space without having to keep it cool all day long.
• Use the Landscape to Your Advantage – Instead of relying solely on your air conditioner to keep the house cool in the summer, plant some trees and shrubs around the house to block the sunlight. Simply adding some shade to your property can directly reduce how much heat your home absorbs throughout the day and reduce how much your AC unit needs to work to keep you cool.
• Ventilate Your Roof – A good third of the heat in your home is absorbed directly through the roof. To keep this heat from affecting the rest of your home, install a roof fan that ventilates the excess energy and keeps the attic at a steady temperature. Less heat up top means less cooling needed down low.

A good air conditioning system is effective no matter what the temperature does, so it’s easy to forget how big your bill will soon be. To avoid an overblown bill, keep an eye on your cooling and follow these simple tips to cut back on use. For more information about how to best utilize your AC in Ajax, call Advantage Airtech!

The air handler is a metal box, usually consisting of a blower and the heating or cooling elements. It might also include dampers and sound attenuators along with an air filtration and humidity control system. The simplest air handlers are designed only to transfer the heated or cooled air to the various parts of your home, while the most advanced devices are designed to perfectly condition and clean that air as it is circulated.

 Types of Air Handler

There are a few different types of air handler as well, depending on the size of your Newcastle HVAC system and the nature of the heating and/or cooling used. Most homes, for example, use terminal units which consist of just an air filter, blower and coil. This very simple system is all you really need to heat and transmit air through your ductwork.

However, for larger systems, there are also makeup air units which use outdoor air instead of recirculated indoor air. There are also packaged and rooftop units which are designed to be placed outside. These devices are most commonly used for commercial applications when space is limited.

How the Air Handler Works

An air handler’s most basic component is a blower fan. This device is run by an AC electric motor and can be either single speed or variable speed depending on the size and scope of your air handler. The dampers on the fan will control the flow rate of the air going through the blower fan. Most residential blowers are part of the air conditioning or furnace system, while commercial systems often have multiple blowers to maintain steady airflow for a larger space.

Because an air handler passes all of the air that will go through your vents, it is the best place to install high quality MERV or HEPA filters to remove pathogens and contaminants. It is also a good place to install humidity control devices .

Your air handler is an incredibly important component in your home heating and cooling system. Without it, all that heated and cooled air you pay for each year wouldn’t reach you. So, make sure to keep your system in tip top condition. To schedule an annual maintenance visit, call Advantage Airtech Heating & Air Conditioning today!

That is, unless you take care to control the seasonal air quality in your home, which can not only help ease the suffering of allergies, but also soothe asthmatics, keep out pollutants and generally promote better overall health.

How do you go about controlling the air quality in your home? To start, try these simple tips:

1. Vacuum carpets regularly. Use a vacuum with a HEPA filter and invest in some allergen suppressing bags.
2. Keep your vents clean. This is also a good maintenance practice to lengthen the life of your ventilation equipment.
3. Dust hard surfaces and wash bed linens weekly.
4. Install HEPA filters in your ventilation system, such as in air conditioners or other air handler units. Use a higher rated filter to keep out more allergens and pollutants.
5. Invest in and use an air purifier. Again, make sure to get one with a HEPA filter.
6. Have your home tested for radon and carbon monoxide. Have smoke, carbon monoxide and radon detectors working properly at all times.
7. Use a humidifier to keep overly dry air from irritating sinus passages.
8. Keep doors and windows closed tight, especially during allergy season(s).

By taking charge of the air quality in your home, you also take control of a measure of your family’s health. Some of these measures require at least a bit of an investment – for example, higher rated HEPA air filters are often more expensive and need to be changed more frequently – but the benefits to your well being and that of your family are clearly well worth it.

Its most distinguishing feature is the ground loops. The most common is the “closed” ground loop system, which is a series of pipes that are buried underground. These pipes contain a heat transfer fluid, comprised of antifreeze and water. This fluid absorbs heat from the ground and carries it to the home. This fluid also absorbs heat from the house and sends it into the ground to keep the home cool.

Examples of closed loop systems include the horizontal closed loop, which can be used in larger parcels of land (over an acre for example). The loops are placed typically placed horizontally 6-to-10 feet below the surface. A vertical closed loop design is recommended for smaller parcels of land and loops are often buried vertically approximately20 feet underground. Other types of ground loop designs use well water to transfer heat in an open loop configuration, or have a closed loop submerged underwater in a pond or lake.

The next component is the heat pump, which draws the fluid from the ground loop. In a heat pump, heat energy is exchanged with the ground to heat or cool the home. In the heating mode, fluid warmed from underground flows through the heat pump. A fan blows across the pipe warmed by the fluid. Because the fluid is much warmer than the air inside the heat pump, heat energy is released into the cooler air. The cool air is warmed and distributed inside the home. The process is reversed for cooling. Cool fluid in the pipe absorbs heat from the warm air inside the home. Once pumped underground, the excess heat in the fluid is absorbed by the cooler earth.

The final component is the air handling or distribution system. Here, a fan in the heat pump’s furnace blows air over a fan coil and the heated cooled air is distributed through the home’s ductwork. Some distribution systems are hydronic, where hot water is circulated through radiators or radiant floor heat tubing. This water absorbs heat from the heat pump and then distributed throughout the home.

In some homes, both a forced air and hydronic system, often referred to as a “hybrid system” work together.

Optional components include a heat pump “desuperheater,” which is used to help with domestic hot water heating. In warm weather, the desuperheater recovers some of the heat – that would otherwise be sent to the ground loop – to help produce hot water. In cold weather, some of the heat pump capacity may be diverted from space heating for the same purpose. Desuperheaters save approximately 25% on domestic water heating costs.

Another component is an auxiliary electric heater, which is built into the geothermal heat pump This auxiliary electric heat is installed to allow heating and cooling technicians to size – or resize – your Durham geothermal heat pump system to assist the system during the few coldest days of the year. Auxiliary electric heat is also an emergency backup heat source if there are any operational issues with the geothermal heat pump system.

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.

For older systems, or ones that have been repaired all to often lately, or ones that seem to be on their last legs, repair may be the only reasonable course of action.

Surely you know that a total system replacement would be a big job, but have you ever thought about just how big? Sure, you know you will have to swap out the failing furnace, and you may as well replace the air conditioning unit while you’re in there, but that’s it, right?

Actually, there is a lot more to your Durham HVAC system than just those two machines. Think about all the behind-the-scenes components and the little components that are often overlooked, such as:

• Ducts – Keep in mind that your ducts are probably as old as that furnace you are replacing, and that a new, efficient unit cannot operate at nearly its full potential with faulty duct work.
• Thermostats – Your old ones may not even be compatible with a new furnace or air conditioner.
• Wiring – For the thermostat, among other things.
• Insulation – Many homeowners forget that insulation is part of an HVAC system, too. Just like we said about duct work, old insulation does not help a new system achieve maximum performance.
• Piping – Such as refrigerant piping on a geothermal system or a ductless air conditioning system.

You can see that the job starts to get pretty complex pretty fast. This doesn’t mean you should shy away from a necessary replacement of your Durham heating system, just make sure that you fully consider the scope of what you need done, as well as the budget and time frame you have to work with.

Contracting with a company like  Advantage Airtech ensures consistent maintenance and oversight to allow home owners the comfort and relaxation you deserve in your own home.

Back to Basics

Usually in the basement or a central location, a furnace heats air to a temperature set by the thermostat.  Over the years, technological improvements have enabled furnaces to be much smaller and fit into closets instead of the large and gangly monsters of old that could fill an entire basement.

By a fan in the furnace, the warm air is circulated through filters into a system of ducts to be distributed to grates in the wall or registers on the floor.  A second grate and duct system returns cooler air back to the furnace to be reheated.

Water can be added at the furnace to humidify the air and filters are able to remove some of the dust that typically floats invisibly throughout a home.

The Dangers of Not Changing the Filter

When the system is properly maintained, it is clean, efficient and produces comforting heat on demand at the touch of the thermostat or consistently throughout the day and night.

The furnace filter is designed to remove dust from air as it passes through your furnace. The longer your furnace filter is in place the dirtier it becomes. The increase of particles caught in the filter creates resistance to air flow through the filter and reduces efficiency.

To make up for the loss of flow through a dirty filter, the heat exchanger, usually a gas or oil fired flame, must work harder to produce the same amount of heat to the space.  This becomes costly financially and causes undo wear and stress on the equipment, requiring a partial or full replacement much sooner.

Additionally, operating above ideal designed conditions, cracks in the chamber may appear from the over load which can allow carbon monoxide, a toxic gas, to be released into the duct work.  This gas in large quantities in the home can cause headaches, nausea, and in extreme circumstances, even death.

Regular Maintenance

To avoid problems and excessive strain, remember to change the filters at the beginning of each new heating season.  An annual maintenance, check-up and thorough cleaning by a qualified company like  Advantage Airtech ensures a safe and comfortable season of warmth with no need to worry about the dangers of not changing filters in your Bowmanville furnace.

However, an important factor to consider before choosing an open loop system is the quality of the water coming from the source. Although you won’t drink the water, the quality still matters a great deal, as poor water quality can cause serious problems in your geothermal system.

Let’s take a look at some common water quality problems and the damage they can potentially do to an open loop geothermal system.

 Mineral Deposits

If the water is filled with minerals — frequently called “hard water” — those minerals can be deposited within the geothermal coils. As they build up on the walls over time, they can slow the flow of the water or even clog it completely.

Hard water does not necessarily preclude the use of an open loop system. It just may call for extra maintenance, such as periodically flushing the system with a mild acid solution to remove mineral build-up.

 Impurities

Impurities in water, especially metals like iron, can also cause clogs. Most frequently this occurs in the return well of the geothermal system. Again, these impurities do not necessarily mean an open loop system can’t work for you, but you should consult with your Uxbridge contractor prior to installation for solutions to this problem.

 Particulate and Organic Matter

If you plan to use surface water such as a pond or spring as the source for your open loop system, make sure to test the water composition thoroughly. An excess of sediment or organic matter can clog up your geothermal system very quickly.

Ideally, these are all situations that your contractor will anticipate and discuss with you ahead of time, so that your open loop system can be installed in such a way as to preempt any problems with water quality.

An undersized furnace will turn off and on frequently, which is called short cycling. Short cycling can lead to moisture in the system, causing less efficiency and damage to equipment from accumulating moisture in the heating system. The constant cycling adds to wear and tear on equipment, too. An oversized furnace may not be able to keep up with the demand for heat during the coldest days. The furnace may be constantly running and unable to keep up – adding to higher utility costs. So size really does matter when it comes to selecting the right heating equipment for your home.

But a big furnace does not mean it is right-sized. Have you ever seen a “five-way” gravity furnace? It was manufactured in the mid-1900’s and took up a lot of room – as much as half of a basement – while being extremely inefficient. The key here is efficiency. A furnace that works right is sized to the space it is heating, which does not include attics, crawlspaces, or uninsulated rooms (porches, mud rooms, etc.).

A furnace must make efficient use of its Btu’s, which is abbreviated for British thermal unit. Btu is used to measure a furnace size. Furnaces are often rated by input Btu, which is the amount of energy consumed when running. The output Btu may be different based on the system. And output Btu is the best way to select a furnace, since this is the actual heating capacity.

When sizing  your Durham Region furnace, the first thing to do is to determine the inside space that will be heated. If you are looking to heat your home, you can measure the square footage of each room (multiply width by length). The rooms should include bathrooms and hallways but exclude attics and crawlspaces. Add up the totals and match up the Btu output to the total square footage. If you aren’t sure of your calculations, call a qualified heating and cooling contractor.

There are many factors that go into heating a home and today’s energy efficient furnaces give homeowners many more choices. Whatever furnace you choose to purchase, make sure you do your homework and hire Advantage Airtech to help you determine the best size furnace for your home.
