Tips to Keep Your Furnace & Duct Systems in Tiptop Shape

Ultra Violet Lighting- Purify Your Air

calgary furnace ultra violet lights

Most of us take our health for granted. Air quality easily ranks as one of the most influential factors on our health. UV Air Purifiers kill the bacteria and viruses that is brought in from the outside, ensuring the air you breath inside is clean. The City of Calgary uses similar technology to treat our water. This same light is applied in the home.

Indoor Air Pollution Is A Serious Threat

Pollen, mold, allergens, and bacteria are just a few of the microbial hazards that spread through the air. Stopping these pollutants at the heart of your home, the furnace, insures your home is defended.

The US Environmental Protection Agency(EPA) & the World Health Organization(WHO) are both warning the public about how serious this issue has become:

"...our indoor environment is two to five times more toxic than our outdoor environment,…” ~ EPA

“... The WHO have concluded that 80% of all cancers are attributed to environmental (i.e. Air Pollution, Food, Water, etc.) rather than genetic factors, including exposure to carcinogenic chemicals, many of which are found in household cleaning products.”

“... almost 3% of the global burden of disease is due to indoor air pollution.” ~ WHO

Not All Furnace Air Purifiers Are The Same

The portable units are basically electric dust filters and only cover one room. Adding a whole home high output UV germicidal lamp in your furnace works by breaking down the electron bonds of an organic molecule.

This intense light penetrates airborne microorganism, causing their cellular makeup to be destroyed, killing them or rendering them harmless and/or prevents them from reproducing.

*Note:If you have central air conditioning a UV air purifier can be the perfect match in your home. Condensation from your a/c coils can increase the bacteria and mold. A UV lamp will kill these.

The numbers are impressive!

• Reduce potential illness at an alarming rate

• UV air purifiers have a 93% viral and bacterial eradication efficiency.

• Help your home smell fresh

• UV air purifiers have up to 88% odor removal rate.

• UV air purifiers neutralize harmful fumes

• By eliminating 80% of chemical vapors such as ozone.

Breathe easier knowing you're leaving the pollutants outside!

Choosing the Right HVAC Company

You know that dirt, dust, and other contaminants can over time build up in your ducts causing your HVAC systems to stop functioning properly. When you decide to have your ducts cleaned, or your furnace serviced, it’s important to be aware of the “scams” out there. Here are some warning signs of a duct cleaning scam:

Prices way to cheap

If it seems like too good of a deal than there’s a catch. Often companies will say they can clean your home for $99. That sounds great right! But often these “deals” have hidden charges like a limited number of ducts, that will add up by the time the bill comes. Read the fine print ask many questions. Never pay a deposit on a cleaning service. Payment should be accepted after you are happy with your service. When it comes to other services involving parts a deposit on the part can be required.

Many Complaints

There are many reliable sites online where you can check how other homeowners rate the services of duct cleaning companies. The Better Business Bureau (BBB) also have complaint records for companies available online. Some complaints can be a good thing. You can't make everyone happy! However, if you find multiple negative reviews and complaints about a company you should be aware.

No Online History

If you find nothing about a company when you attempt to research their reputation online, it's a sign that they're either inexperienced or a fly-by-night company. Also, a lot of Facebook adds are out there, if they don’t list their company name or links to a website this is a red flag that their services may not be legitimate.

Scare Tactics

When a company is using scare tactics to get you in this should be a warning. Especially with duct cleaning, there is no emergency to your systems bad enough to warrant a rush with booking. You have time to do the research and ask questions. If they are forcing you to book right away than they are stopping you from checking into their company.

Lack of Knowledge

When you ask, a trustworthy and experienced service provider should be able to explain their cleaning process in detail. If you are asking questions and they cannot answer them, you should worry about their skills. A proper way to clean the ducts in your home is with a powerful vacuum and air hose introduced at specific access points to remove debris. They should also be checking and cleaning your HVAC equipment too so your entire system is contaminant-free.

These statements above also apply to other services provided but an HVAC company. Ask questions do your research. If a company is trustworthy they will give you the time to do the research, as they know you will come back to them. If you would like to avoid scams and be provided with honest reasonable prices, call Air Raid Furnace & Duct today!

Programmable Thermostat

We are constantly coming and going from our homes. Remembering to change the thermostat every time is a pain, and if you forget it costs you money. Having a programmable thermostat will take this worry out of the day, and save you money on your utility bill.

Programmable thermostats are capable of scheduling multiple times a day. This allows you to set wake up and leave times in the morning, and arrival and bedtime at night. You can even set a separate setting for the weekends. Most programmable thermostats are easy to set. If you need to change the temperature outside of the schedule no problem. They have a temporary setting that will reset on the next cycle.

There are many options when choosing a thermostat. Basic ones are easy to use and are a cost-effective option for your home. Some thermostats can connect to your phone allowing you to make adjustments while not at home. They can be more complicated to use however and do cost more. Whichever you decide having a programmable thermostat will save you money and is a good idea to have in your home.

Cold Air Returns, Not Just A Vent on Your Wall


Your planning the perfect arrangement of your furniture in each room of your house. You know you don’t want to cover the heat register or that room could be cold, but what about the other vent in the room? Blocking the cold air return is the easiest way to weaken your heating and cooling system.

What is it?

Cold air returns do exactly what they are named, they provide air back into your heating systems. When they are blocked it reduces the airflow to your blower. If you block this it doesn’t slow your fan it creates positive air pressure. This means that instead of pulling air easily back into your system, your furnace fan will pull air in through cracks and holes in your ducting, house, windows and doors.

Why is this a problem?

Anytime air flow is restricted it causes premature problems.When heating your home improper air flow can cause the heat exchanger inside the blower compartment to store to much heat. Over time this will cause a crack. When the cracks become too big, carbon monoxide can leak into your home. Not only is this extremely dangerous to your health, but you will also need to replace your heating systems. Any cracks need to be addressed immediately.

When running your air conditioning, limited air flow can cause the evaporator coil to keep refrigerant inside to stay longer than it should. This can cause the coil to freeze over. This will make your air conditioner inefficient. The frozen coil can cause water damage. Also if the system doesn’t turn off in time damage to the outside compressor can cause a very expensive problem.

The cold air returns are an essential part of your heating and cooling system. Checking them from blockage and debris is an important maintenance step that is easy and can save you money.

Carbon Monoxide

Carbon Monoxide fumes

We’ve all heard the saying don’t fix it till its broken. Its a good rule of thumb, however, this doesn’t work for carbon monoxide detectors or smoke alarms. Just like car seats and helmets CO detectors have a lifespan. When it comes to protecting your family, it’s better to replace detectors than risk failure.

What is Carbon MonoxideAnything that burns fossil fuels — from cars, gas heaters and stoves, water heaters to propane heaters and lamps — can produce carbon monoxide when the fuel isn’t burned efficiently.It is odorless, tasteless and invisible. Carbon monoxide (CO) is even more dangerous because victims have little warning of its presence. Because of this CO detectors are even more important than smoke detectors. With most municipalities, it is not regulation to have CO detectors as it is with smoke detectors, so it is important for homeowners to stay on top of it.

How Long They LastSmoke detectors typically last 10 years and CO detectors seven years. They have a manufacturing date that is stamped on the device. If you are needing to replace the batteries and the date is close it might be a great idea to purchase a new one. Detectors also have a test button which you should be checking regularly. If there is no chirp sound change the batteries, if there is still no sound throw out the detector and by a new one. The alarms are inexpensive.Batteries in smoke alarms should be checked every 3 months. In CO detectors battery life is not as long so they should be checked monthly. You cannot smell or see carbon monoxide as you can with fire smoke so it's important to be on top of the batteries.

Choosing New DetectorsThere are many options when purchasing smoke and CO detectors. Look for ones with the UL (Underwriter’s Laboratory) label. It is best to get CO detectors that plugin and have the backup battery. You can even get ones that tie into your home security system.There are many different types with different benefits so a little bit of research before purchasing can help you make the best choice for your home.Smoke and CO gasses both rise and the detectors should be placed higher on the walls, but CO detectors need to be positioned properly.The International Association of Fire Chiefs recommends placing at least one CO detector on each floor or level of your home. If using only one CO detector, place it close to your bedroom, so you can be awakened by the alarm. All appliances emit small amounts of carbon monoxide, so place your CO detector no closer than 15 feet from the source to prevent false alarms, steamy bathrooms can also produce false alarms.

In the end, your family safety is important. Little steps like ensuring your detectors work can add peace of mind and help you sleep better. If you have any other questions or concerns please feel free to call or ask.



Controlling The Dust In Your Home.

Everyone wants that completely spotless house. If you don’t have kids this might be a possibility. However no matter how hard you try dust may still be lurking in your home. Having a complete dust free home in Calgary may be impossible but there are ways of controlling the amount.


Replace Your Filters

As a homeowner, I’m sure you are aware that your furnace has filters. These filters collect the ducts, hair, and allergins that are collected from your cold air returns, and from the fresh air intake. There are many different filters, but which one do you choose? Read here to understand furnace filters!

Purchase an Air Purifier

Air Purifiers stop the dust from circulating and can be especially beneficial to household members who are especially sensitive to the dust in the air. Just be aware that you'll need one for each room you want to keep dust-free.

Vacuum on a Regular Basis

If your home has carpets it is especially important to vacuum 2-3 times a week. Dust and other debris become trapped. If you have hardwood floors you will notice the dust more, it's not hiding in your carpet, so vacuuming often can collect the dust.

Dust with Microfiber Cloths

My Mom told me that it is great to get a good feather duster. Today that statement isn’t true. Feather dusters just stir up the dust causing it to settle elsewhere. Microfiber cloths use an electrostatic charge that will capture the dust, instead of spreading it around.

Wash Your Bedding Weekly

You may not want to think about it, but the truth is that our bedding is a nesting ground for dust. Don’t believe me just look under your mattress or bed. If anyone in your household has been suffering from respiratory problems, washing the bedding on a weekly basis can help.

Reduce Clutter

The more "stuff" you have sitting around your home, the more places for dust to collect. Remove piles of books, boxes, and anything else that might be making barriers for dust and hair to settle. It's an easy solution that will definitely improve your home's air.

Duct Cleaning

If you are doing all these things and still find that you have too much dust in your home the problem might be in your ductwork.  Having regular furnace and duct cleaning can remove the dust and debris that is lurking in the vents of your home. This is a preventative measure that will not magically make your home dust free but it can help.

Understanding Filter Ratings

As a homeowner in Calgary, you know you need to change your furnace filters regularly. You may have been in the stores looking at furnace filters, feeling confused about all the options, and wondering which filter will be best for your home. On filters, there is a MERV rating. This can help you decide which one is best for you, however, you need to know what that rating means.So what is a MERV Rating exactly? First off, MERV stands for


1. The higher the MERV rating on a filter, the fewer dust particles, and other contaminants can pass through it. What does this mean for you? As a homeowner, you want to be sure your family is safe and healthy, right? Well, changing your filters regularly will certainly help with that, but the MERV rating on the filters you buy is also important.2. MERV ratings dictate the price you pay. You may think on the surface that MERV 11s are better than MERV 8s, you may be wrong. MERV 8-rated filters capture 70%-85% of mold spores, hair spray, fabric protector and cement dust measuring 3 to 10 microns in size. MERV 11 air filters capture 65%-70% of humidifier dust, lead dust, auto emissions and milled flour measuring 1.0 to 3.0 microns in size and 85% or better for the same pollutants measuring 3 to 10 microns in size. So you might not want to spend the extra cash on the Merv 11 filter when the Merv 8 filter may be cheaper and comparable to the Merv 11 one. Depending on where you buy your filters you can save money knowing the facts.3. For optimal home comfort, adequate airflow is necessary to regulate temperature and keep allergens out. For most homes, a MERV rating between 8 and 11 is perfectly fine. Higher MERV ratings may be more desirable to you if you have family members, particularly children, and older folks, who suffer from allergies and asthma.

Considering the MERV rating on your air or furnace filters in Canada is a helpful way to identify the capabilities of different large air cleaners. Determined through rigorous testing and given the worst-case performance of the filter, the MERV number remains a good indicator of performance. That being said, there are other factors at play here as well, so don’t assume that buying the right air filtration system is a simple matter of choosing the unit with the highest MERV. For example, most brands out there today use electrostatic charges to boost the filter’s rating. However, like a balloon that you rub on your head and place on the wall, that charge will only last a few hours. Same with filters: the electric charge eventually dissipates and reduces the filter’s efficiency after just a few hours of operation. Look for filters that have a mechanical vs electrostatic rating, for example, the Merv 8 30/30. One thing to note is that with better technotongy many furnaces still prefer the cheaper filter. With higher Merv ratings you need to be on top of filter changes to prevent filter clogging.
