Last month we told you some things to look for that would indicate that your HVAC system needs attention from a specialist. However, a quick fix isn’t always the answer – sometimes the best action is to replace your system entirely. Replacing your system can seem like a large cost upfront, but a new, more efficient system will save you more money over time by reducing your energy bill and minimizing the need for maintenance and repair. Energy Star offers a check-list of signs that indicate that a system needs to be replaced.

The age of your system is a solid indicator of when it will need to be replaced.  Talk to a professional about replacing your system if

  • Your furnace or boiler is more than 15 years old.
  • Your air conditioner or heat pump is more than 10 years old.

Some signs that you system needs to be replaced are obvious and easy to spot, and occur from daily use, such as:

  • Uneven temperature throughout the home; some rooms are too hot while others are too cold.
  • Your cooling or heating system is excessively noisy.
  • Your energy bills start to increase suddenly.
  • Your equipment needs frequent repairs.

You can also spot a system that’s on its way out by some factors that may seem less obvious:

  • Your home is exceptionally dusty, which could be caused by leaky ducts.
  • Your home has problems with keeping a consistent humidity; faulty equipment and leaky duct work can cause air to be too humid in the summer or too dry in the winter.

Let us know if you have noticed any of these signs in your home or if you any questions about upgrading or replacing your system. You can also reach out to us on Facebook or Twitter.

Casteel Heating and CoolingFreon or R-22 as its known in the trade, is being phased out. What does that mean for you? It means you can no longer purchase a new HVAC system that uses Freon. But wait? Can I still get Freon? Yes, you can for now AND Casteel Heating and Cooling, you won’t pay for Freon!

In 2010, manufacturers were to stop making R-22 according to the guidelines of the EPA. Now it has to be recycled and recovered and beginning in 2020, all R-22 used will need to be those types. For now, you can still get it and Casteel has it!

So never fear, Casteel Heating and Cooling is here!

No matter how long the winter, spring is sure to follow.  ~Proverb

Thank goodness for that! With Spring comes blue skies, warmer days, longer nights and…..spring cleaning?

That’s right…spring cleaning. What do we have to do with spring cleaning? There’s never a better time to get your AC in shape for the Spring and Summer months! We have complied a list of things you can do to prep your HVAC for the change in seasons.

  1. First and easiest thing to do? Change your filters! This isn’t just for Spring but now is a good time to do it!
  2. Pop your head into your attic to see if your ducts are sealed properly. How would you know? If you have the air on and it’s cold in your attic, you have a leak.
  3. Take a look at your condenser unit outside and see if it looks clean and free of debris that might stop the blades from running. During the winter leaves or dirt can get in there from the weather and they need to be removed.
  4. Make sure your exterior pipes are still properly insulated and protected from the weather. They can take a beating over the Winter months.

One of the first tests we perform when replacing your HVAC unit is a Manual J “Residential Load Calculation.” This test ensures that your new unit is sized properly for your home. recommends the following:

Correct system sizing requires considering many factors other than simply reading the nameplate of the existing unit. Key factors for correctly sizing a heating and cooling system include the following:

  • The local climate
  • Size, shape, and orientation of the house
  • Insulation levels
  • Window area, location, and type
  • Air infiltration rates
  • The number and ages of occupants
  • Occupant comfort preferences
  • The types and efficiencies of lights and major home appliances (which give off heat).

We have posted regarding safety and Carbon Monoxide before but we can NOT stress enough how important it is for you to be extremely careful during the cold season.

Here are some potential Carbon Monoxide dangers in your home:

  • CO is a produced anytime a fuel is burned. Potential sources include gas or oil furnaces, water heaters, space heaters, clothes dryers, barbecue grills, fireplaces, wood-burning stoves, gas ovens, generators, and car exhaust fumes.
  • CO poisoning is the leading cause of accidental poisoning deaths in America. (Centers for Disease Control)
  • Every year more than 10,000 people die or seek medical attention due to CO poisoning from home-related products. (Consumer Product Safety Commission)
  • More than two-thirds of Americans use gas, wood, kerosene or another fuel as their home”s major heat source.
  • 65% of CO poisoning deaths from consumer products are due to heating systems.
  • Only 27% of homes in America have carbon monoxide alarms, according to the Hardware/Homecenter Research Industry.
  • An idling vehicle in an attached garage, even with the garage door opened, can produce concentrated amounts of CO that can enter your home through the garage door or nearby windows.
  • CO poisoning deaths from portable generators have doubled for the past two years, and many of these deaths occurred in the winter months and during power outages.
  • A poorly maintained gas stove can give off twice the amount of CO than one in good working order.

What you can do to prevent Carbon Monoxide from leaking into your home.

  • Install at least one battery-powered CO alarm or AC-powered unit with battery backup on each level of your home and near sleeping areas.
  • Do not use charcoal or gas grills inside or operate outdoors near a window where CO fumes could seep in through a window.
  • Check all carbon monoxide alarms in your home. Do they use the most accurate sensing technology? Do they need new batteries?
  • Replace CO alarms every five to seven years in order to benefit from the latest technology upgrades.
  • Have a licensed professional inspect heating systems and other fuel-burning appliances annually.
  • Install fuel-burning appliances properly and operate according to the manufacturer’s instructions.
  • Keep chimneys clear of animal nests, leaves and residue to ensure proper venting. Have all fireplaces cleaned and inspected annually.
  • Do not block or seal shut the exhaust flues or ducts used by water heaters, ranges and clothes dryers.
  • Do not leave your car running in an attached garage or carport.
  • Do not use ovens or stoves to heat your home.

Deciding Whether or Not to Have Your Air Ducts Cleaned

Knowledge about the potential benefits and possible problems of air duct cleaning is limited. Since conditions in every home are different, it is impossible to generalize about whether or not air duct cleaning in your home would be beneficial.

If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth), having your air ducts cleaned is probably unnecessary. It is normal for the return registers to get dusty as dust-laden air is pulled through the grate. This does not indicate that your air ducts are contaminated with heavy deposits of dust or debris; the registers can be easily vacuumed or removed and cleaned.

On the other hand, if family members are experiencing unusual or unexplained symptoms or illnesses that you think might be related to your home environment, you should discuss the situation with your doctor. EPA has published Indoor Air Quality: An Introduction for Health Professionals and The Inside Story: A Guide to Indoor Air Quality for guidance on identifying possible indoor air quality problems and ways to prevent or fix them.

You may consider having your air ducts cleaned simply because it seems logical that air ducts will get dirty over time and should occasionally be cleaned. While the debate about the value of periodic duct cleaning continues, no evidence suggests that such cleaning would be detrimental, provided that it is done properly.

On the other hand, if a service provider fails to follow proper duct cleaning procedures, duct cleaning can cause indoor air problems. For example, an inadequate vacuum collection system can release more dust, dirt, and other contaminants than if you had left the ducts alone. A careless or inadequately trained service provider can damage your ducts or heating and cooling system, possibly increasing your heating and air conditioning costs or forcing you to undertake difficult and costly repairs or replacements.

You should consider having the air ducts in your home cleaned if:

There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system. There are several important points to understand concerning mold detection in heating and cooling systems:

  • Many sections of your heating and cooling system may not be accessible for a visible inspection, so ask the service provider to show you any mold they say exists.
  • You should be aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and may require laboratory analysis for final confirmation. For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it.
  • If you have insulated air ducts and the insulation gets wet or moldy it cannot be effectively cleaned and should be removed and replaced.
  • If the conditions causing the mold growth in the first place are not corrected, mold growth will recur.

Ducts are infested with vermin, e.g. (rodents or insects); or
Ducts are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.
Other Important Considerations…

Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts or go down after cleaning. This is because much of the dirt that may accumulate inside air ducts adheres to duct surfaces and does not necessarily enter the living space. It is important to keep in mind that dirty air ducts are only one of many possible sources of particles that are present in homes. Pollutants that enter the home both from outdoors and indoor activities such as cooking, cleaning, smoking, or just moving around can cause greater exposure to contaminants than dirty air ducts. Moreover, there is no evidence that a light amount of household dust or other particulate matter in air ducts poses any risk to health.

EPA does not recommend that air ducts be cleaned except on an as-needed basis because of the continuing uncertainty about the benefits of duct cleaning under most circumstances. EPA does, however, recommend that if you have a fuel burning furnace, stove, or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning. Some research also suggests that cleaning dirty cooling coils, fans and heat exchangers can improve the efficiency of heating and cooling systems. However, little evidence exists to indicate that simply cleaning the duct system will increase your system’s efficiency.

If you think duct cleaning might be a good idea for your home, but you are not sure, talk to a professional. The company that services your heating and cooling system may be a good source of advice. You may also want to contact professional duct cleaning service providers and ask them about the services they provide. Remember, they are trying to sell you a service, so ask questions and insist on complete and knowledgeable answers.

Because this seems to be more prevalent in the winter months than any other time, we strive to make sure that you have all the ammunition you need to defend yourselves. We are reposting a story from the small business site that addresses the issue.

With colder temperatures comes a silent threat from fuel-burning appliances — carbon monoxide.

“We get a lot of false alarms throughout the year, but this is our busiest time for actual elevated levels of carbon monoxide in people’s homes,” said Jacksonville Fire Department Capt. Bryan McGee, fire prevention and education officer.

Such calls typically start in mid-October when people begin using wood stoves, fireplaces, kerosene heaters or gas-powered furnaces — all of which produce carbon monoxide emissions in levels usually not harmful, McGee said.

But when appliances are used improperly or are not working right, the colorless, odorless toxic flammable gas becomes hazardous.

Such was the case Sunday, when a malfunctioning furnace caused a “dangerously high” level of carbon monoxide inside a South Jacksonville church.

No one inside the Church of Jesus Christ of Latter-day Saints at 1053 E. Vandalia Road became ill and South Jacksonville Fire Chief David Hickox said firefighters vented the building, shut off the furnace and advised church officials to call someone to fix the problem.

About 95 percent of Jacksonville’s calls turn out to be false alarms caused by faulty sensors or low batteries in carbon monoxide detectors or by old or damaged heat exchangers in furnaces, McGee said.

“In some homes, we have had levels that are extremely high and a few poisonings because of it,” he added.

There have been no carbon monoxide poisoning incidents so far this year.

In addition to having equipment to check the carbon monoxide level of a building, the Jacksonville Fire Department can check those inside for possible poisoning. With its portion of a public safety grant earlier this year, the fire department bought two finger-clamp monitors to measure the level of carbon monoxide in the blood.

Symptoms of carbon monoxide poisoning include headaches, nausea, shortness of breath, unusual fatigue, dizziness and confusion.

An estimated 170 people die each year and thousands of others end up in hospital emergency rooms because of carbon monoxide poisoning.

To avoid the risk, McGee suggests people have fuel-burning appliances and water heaters checked before winter by a qualified technician. Fireplaces should be checked regularly to ensure they are in proper working order and properly ventilated. Chimneys should be cleaned annually.

State law requires an approved carbon monoxide alarm be installed within 15 feet of a bedroom in most residences. An exception is those that have all-electric power — no gas heat or a gas water heater — and do not have fireplaces or attached garages.

McGee said it’s important to replace the batteries in the detectors regularly. Carbon monoxide detectors more than three years old probably need to have the sensor inside replaced, McGee said.

Intermittent beeping every 30 seconds to a minute can indicate a low battery or a bad sensor.

If the detector’s alarm sound is constant, “then it’s an obvious incident of carbon monoxide,” he said.

If that happens, get out of the house immediately and call for help from a safe location outdoors or from a neighbor’s house.

Please heed these warnings. If you want to be sure that you’re safe, let Casteel Heating and Cooling come take a look. We care.
