The Hardest HVAC Maintenance: A Tip from Monroe

Friday, November 11th, 2011

Do you hate to work on your own mechanical equipment in your Monroe home, like furnaces and plumbing fixtures? You aren’t alone. Many people are not cut out to be do-it-yourselfers (DIYers). They prefer to hand off their maintenance and repair chores to qualified professional. That’s not a bad thing. But there are lots of DIYers who prefer to work on their own home repairs – and those are the people who aren’t afraid to take on the most challenging jobs.

If you are looking for good ideas on how to maintain your home’s heating and cooling (HVAC) system beyond the normal filter changeouts, here are some good things to check – things that will help with the overall performance of your HVAC system.

  1. Check the ventilation system. The ventilation carries conditioned air from a main source throughout your home.  It takes a little time and effort to check your ventilation system for things like cracks or leaks around joints, but it is an important maintenance task. You may even find separations between joints or holes caused by nails. A leaky ventilation system could be sending conditioned air into attics, walls, or crawlspaces and making your furnace work extra hard just to keep your living areas warm and comfortable. Take time to visually inspect as much of your ventilation system as possible – usually metal or flex duct – and repair using joint glue, metal filler, or duct tape.
  2. Inspect the insulation. Your heating system works in conjunction with the insulation in your home to provide comfort and warmth while saving you on high utility bills. A home that is poorly insulated or not insulated at all will cause a furnace to work harder and not only send utility bills higher, but increase the possibility of mechanical failure. Replacing or adding insulation in walls and crawlspaces is a relatively easy, yet time-consuming task. You can roll down or tack up fiber insulation or blow in insulation into walls. You can also seal up cracks on your home’s walls, roof, or foundation with a number of different products. Once again, your goal is to make your heating system work less and save you money.
  3. Check the visible components of the furnace. A build-up of dust and dirt can make the moving components of your furnace work even harder, such as the motors, fan belts, contactors, etc. If you live in an area where there is lots of dust and humidity or if your home has several occupants and/or animals, it is particularly important to check your system on a regular basis. This can be done by removing the access panels and taking a vacuum cleaner hose into as many areas as possible. A good, thorough vacuuming should produce immediate results and make your furnace run much more efficiently.

Try these three steps and you may not have to repeat them for another year or so – possibly not ever again while you live in your home.

Will My Air Cleaners Reduce Health Risks? A Question from Monroe

Friday, October 28th, 2011

There is a lot of talk these days about how important it is to have a good air cleaner in your Monroe home. If you don’t have one, you’re putting yourself at risk, or so says common knowledge. But, do air cleaners really reduce health risks, and if so, by how much?

What Air Cleaners Do

Before we can say whether an air cleaner has any positive health effects, we must first look at what they do. Air cleaners are designed to remove certain particles from the air inside your home. Different air cleaners are designed for different levels of removal.

Ratings like the MERV of an air cleaner measure how small of particles the device can remove. Additionally, the type of cleaner will determine what it is best at removing. Mechanical filters are the most efficient at removing dust, pollen, and dander while electronic filters are best for smoke, bacteria and mold spores.

So, What Impact Does this Have on Health?

The big question then is what kind of health benefits you will gain from a high end air cleaning system. If your home isn’t prone to a large number of contaminants and you have good ventilation, the difference may not be that big, but for those with a well-sealed home, pets, humidity problems or any number of other indoor air contaminant sources, an air cleaner has a tremendous impact on your health.

The problem is that when the house gets sealed up so tightly, we put our bodies at risk of contamination from gasses and pollutants that would otherwise dissipate into the air. Those with asthma are put at an increased risk as they breathe in a variety of different triggers like dust, mold and dander.

An air cleaner removes these threats and while they don’t have a proactive effect on your health – you won’t suddenly lose weight or never again get the flu – they can remove many of the negative effects that poor air quality has on your body.

So, should you get an air cleaner for your home? In most cases, the answer is yes, but if you’re still not sure, consider getting your air quality tested. This way you’ll know exactly what you’re breathing and what kind of impact it’s having on the health of you and your family.

How is Geothermal Different Than Other Heating Systems? A Question From Preston

Friday, October 7th, 2011

There are many methods to heating a building in Preston. Early methods included burning coal and wood. Today, sophisticated building controls call for more efficient means of heat – and a method gaining in popularity is geothermal heating.

Air handling units are only designed to move air from one space to another. How that air is heated from the source is what differentiates geothermal from other energy sources.

To understand some of the differences, let’s look at the definition of geothermal heat. By definition, geothermal heating comes from its direct use of geothermal energy, which comes from below the Earth’s surface. And the Earth is known as the greatest conductor of heat. The constant, renewable temperature of the Earth (56-58 degrees on average below 10 feet) provides a heat source requiring no energy conversion, which adds to heating efficiency and ultimately, the cost to heat a building.

In order to heat a building, natural heat from the ground absorbs a colder refrigerant, which is circulated throughout the ground by a series of polyethelene tubing, which is generally positioned five to ten feet below the surface. This heat is transported via the refrigerant to a compressor inside a heat pump, where it is compressed and the lower temperatures are transformed from around 50 degrees to temperatures much higher, as high as 100 degrees of more. This hotter refrigerant is circulated through the tubing within an air handling unit, where colder return interior air absorbs the heat. The heated air is then carried to a building’s interior via fans. The refrigerant, with the heat removed, now becomes colder as is re-circulated into the ground to absorb the natural, renewable heat. In essence, the ground provides free heat.

Other methods of heating include forced air natural gas, oil, solar, propane, electric, radiant, and steam. Each heat source requires mechanical means to heat up the supply air. For example, natural gas – which is used to heat about half of all U.S. homes – is heated via a heat exchanger in a mechanical furnace, which runs on electricity. Radiant or steam heat is generated by mechanically raising the temperature of water or refrigerant via electricity. These methods differ from geothermal because the natural heat of the Earth provides the means for raising the temperature of the refrigerant used to transport heat to the air handling unit.

One drawback to using geothermal heat compared to other energy sources is the cost to bring this natural heating method into a building. The initial installation of a geothermal heating system is much higher than conventional natural gas heating – for example – because of the cost to install the tubing called a ground loop beneath the Earth’s surface. No other heat source, other than radiant heat, requires a series of tubing to deliver heat. But then again, radiant heat does not require a ductwork system to transport heated air or remove colder air. Geothermal requires a series of metals tubes to heat the refrigerant and the ductwork to move the heated air throughout the building.

On the flip side, its energy efficiency – using the Earth’s natural heat – is much greater than other heating sources resulting in lower utility costs, often fractions of the cost to use other heat sources. Energy savings could pay for the cost of installing the geothermal system over several years – another characteristic of geothermal heating.

What Is a Whole House Pressurization Test and Should I Get One?

Wednesday, July 27th, 2011

If you have a forced air heating or cooling system in your home, you also have a system of ducts through which that heated or cooled air circulates. And most people don’t give a second though to those ducts. After all, if your heating and cooling systems are working, the ducts must be doing their job, right?

Unfortunately, that’s not always the case. If ducts are not working properly, the whole system will be in trouble, even when you don’t realize there is a problem. That’s why a pressurization test is so important – it provides peace of mind knowing that your home’s ductwork is not only properly installed, but that it doesn’t need any special repairs.

Why Pressure Matters

Your duct system depends on proper pressurization to evenly and efficiently distribute air throughout your home. Leaks, cracks or clogs in the system can disrupt that pressure and lead to uneven or inadequate movement of air through your ducts. This causes problems you may not notice, so if you haven’t had your ducts checked for proper pressure in a while, it’s worth looking into.

Improper pressurization causes symptoms like hot or cold spots in your home or an overall drop in the effectiveness of your home heating and cooling system. When loss of pressure is due to a leak that lets in unfiltered air from outdoors it can also lead to a decrease in indoor air quality. Often these symptoms are easy to ignore. But by doing so, you only allow the situation to get worse.

A whole house pressurization test is the best way to determine the state of your home duct system. By using high tech diagnostic equipment, home HVAC professionals check over your entire system to determine whether you have a pressurization problem. If so they can then quickly pinpoint the source. Once that’s done, the repairs are usually quite simple and you’ll get much more out of your home heating and cooling system than you did before.

Even if no symptoms of improper pressurization in your ducts have presented themselves, it’s worth having one of these tests performed. Especially if you don’t know when the system was last checked, a whole house pressurization test can help uncover small problems before they turn into bigger ones. And the peace of mind this provides is well worth the day it takes to perform the test.
