What are UV Germicidal Lights and When Should I Install Them?

Monday, April 23rd, 2012

Ultraviolet germicidal lights are lights that improve indoor air quality in your home by killing the harmful bacteria, viruses, and toxic mold that can cause respiratory problems and other health concerns. These microorganisms spread by releasing airborne spores containing the genetic material used to create a new organism. UV lights use a wavelength of ultraviolet light to destroy the organism’s DNA, which takes away their reproductive capabilities and also kills them.

UV germicidal lights are fairly inexpensive and can be installed to work with your existing forced air heating system. They are typically used in tandem with either an electronic or mechanical air cleaner. While air cleaners can filter pollen and other irritants, UV germicidal lights destroy the viruses and mold spores once these pollutants have been trapped by the air cleaner. After the air has been filtered through your HVAC, it will circulate more easily through system and increase the efficiency of the unit. In addition, UV lights are useful in killing hidden mold growth, which can only be detected by special thermal imaging equipment.

Homeowners with particularly chronic allergy problems or extremely poor indoor air quality choose to install both types of air cleaners, in addition to a UV light, for the ultimate protection from indoor air pollutants—from bacteria to pet dander.  If your home lacks adequate ventilation, or if you are unable to control the source of common pollutants, you might benefit greatly by installing UV germicidal lights. Poor indoor air circulation can exacerbate the spread of harmful microorganisms, so make sure you have proper ventilation if you don’t have UV lights in your home.

UV germicidal lights have also been used to filter tap water because they are more reliable and easier to install than other water treatment systems. However, they are typically used to provide cleaner indoor air.

Call ACI Northwest if you have questions or concerns about the quality of the air inside your Spokane home.

Why Routine HVAC Maintenance Improves Indoor Air Quality

Monday, April 9th, 2012

Furnaces and air conditioners in Post Falls are by far the most common way to circulate air throughout homes, offices and institutions, heating in the winter months and cooling in the summer.  Adjust the thermostat and controlled air is delivered almost immediately.

If a system is not regularly and properly maintained, however, that air can be dirty, dusty and full of odor, having passed through the heat exchanger, filters and ductwork that have accumulated a build-up of residue over time.  IAQ or interior air quality quickly deteriorates.

The Basics

HVAC systems heat or cool air at a central point, often a furnace in the basement.  The air passes through filters to sift out dust and unwanted particles, then travels through a system of ductwork to be delivered to the space.  Return air ducts bring it back to the central point.

Along the way, the air accumulates the dust, germs and debris of the places it inhabits.  Over time, the filters become clogged and eventually contribute more contamination to the processed air than they can clean.  The enclosed and hard to reach ducts are also deposits of dust and decorated with spider webs that are quickly another form of filter that gives back more than it receives.

The Costs

Without routine maintenance, the system runs poorly and distributes more dirt into the living space than it is able to filter and clean, reducing the quality of life for the inhabitants, homeowners, businesses and customers.  Poor air quality can lead to serious health issues as well as the loss of time and productivity.

Not only does the quality of the air decrease, the strain on the system lowers efficiency.  Having to work harder consumes more energy, creating an immediate and noticeable rise in utility bills.  The stress also reduces the lifetime of the system and requires more rapid replacements of parts or the entire furnace, a huge financial cost.

Regular Maintenance is the Easy Solution

To maintain high levels of quality air, it is essential to schedule regular replacements of filters and a clean-out of the ducts.  The filters are accessible as part of the furnace and air conditioners and easily swapped out by the home owner once or (better) twice a year.

Ductwork, however, is enclosed and often out of site, just as easily out of mind and certainly harder to reach.  Calling ACI Northwest and scheduling a duct-cleaning along with an inspection and routine maintenance of the entire system with a licensed company ensures longevity and efficiency along with peace of mind.

Adding a Circuit: Why You Should Hire a Professional Electrician

Monday, April 2nd, 2012

There are many repairs that a savvy homeowner can handle alone. Things like fixing a running toilet, draining and cleaning the water heater annually and even replacing a bathroom vanity are all projects that can reasonably be done yourself.

When it comes to electrical work, however, the job is best left to a skilled electrician. One such project that homeowners are not advised to tackle is adding a circuit to your home electrical system. This is for several reasons, including the complexity of the job at hand, the legal components of local building codes and ultimately, your safety.

 Not an Easy Job

Leaving aside for a moment the dangers of delving into your home’s wiring, adding a circuit is a difficult job to accomplish. Wiring a circuit is a job that requires some skill and training. There are lots of ways to do it wrong, but only one way to do it right.

There may be other challenges, too. For one, your breaker box may not accept another circuit, which means you would have to upgrade to one with a higher capacity. Right away, this project has gotten way more complicated than you would have liked.

 Knowing the Code

Building codes are often complex and difficult to follow, which is why electrical contractors have to spend hours in training learning about changes and modifications to local codes. If you were to inadvertently add a new circuit in a way that violated local codes, you could have a big mess on your hands.

In addition, many local codes prohibit anyone other than a licensed contractor from even performing electrical work– including the homeowner.

 Safety First

Lastly, but clearly most importantly, consider the safety issues involved. Electrical wiring can be a serious hazard, and not working with it safely can result in serious injury or even death.

Professional electricians are trained in how to properly and safely do electrical work so that no on gets hurt or worse.

The urge to do it yourself can be strong, and in many cases it’s OK to follow that urge, but adding a circuit is not one of those times. It’s not worth it. Call in ACI Northwest!

Home Inspection 101 for Shoshone County

Wednesday, March 28th, 2012

When purchasing a home in Shoshone County, it is very important to analyze precisely what kind of investment you are about to make. This type of investigation might be best for a professional home inspector to perform.  They are accustomed to advising potential homeowners on what type of heating repairs or electrical maintenance needs to be done. Remember though, employing an inspector could be pricey, depending on the time and expert level they might require.  But it could be worth the investment since a home is undoubtably going to be worth more than a home inspector’s fees.

For that reason, it can be very helpful if you can take a look at a place on your own first to see if it is even worth making an offer on. Of course, you cannot complete the type of inspection that a professional would be able to do, but you can take a look for some important and easy to spot problems that will give you a good idea whether or not it is even worth taking the process on this house any further.

For instance, you should start by taking a look at the house from a good distance away. Make sure the house actually looks like it is standing upright and that it is even. Sometimes from a distance you can see that a house is actually leaning to one side when that is not obvious up close.

Also, this will give you a chance to check out the lay of the land around the house. Remember, you want water to flow naturally away from your house so that it does not get into the basement and cause a problem on a regular basis. That means that you want the ground to slope away from the house rather than be flat or slope towards it.

Check out all of the plumbing and be sure to run water, flush toilets and thoroughly inspect all bathrooms and the kitchen. You want to see high quality fixtures and good water pressure. Also, check to see how long you have to wait to get hot water at various locations to test the water heater.

Be sure to find out what type of heating system the house has in place as well and how old it is. Even a system that works well will need to be replaced soon if it is more than 10 years old. While this may not necessarily stop you from purchasing the house, the cost of replacing that system can certainly impact the amount you are willing to offer.

What You Need to Know About Water Heater Leaks

Thursday, March 22nd, 2012

In Cheney a leak in your water heater can be a big or small problem depending on where the leak is, how severe it is and whether it requires repair or replacement. Here are some things you should know about tank water heater leaks that will help you determine who to call and how to act.

Where Is the Leak?

Step one is to determine where the water is coming from. Look for leaks around the fittings and valves attached to the device. If one of them is loose or if you see water dripping from a connection, it can probably be fixed relatively easily. However, if the leak is coming from the body of the water heater, you may have a ruptured tank which is a sure sign of a bad water heater that needs to be replaced.

Draining Your Tank

Once you identify the leak, turn off the water supply to the tank and prepare to drain it the rest of the way. You should also disconnect the power from the device. If the water heater is gas, I recommend you call a professional who is certified to work on gas appliances. For electric water heaters, you may still want a professional, but the next step here is to simply turn off the breaker to stop electricity from flowing to the device.

Drain the tank next, using the bucket to capture the water as it is released. If you have a floor drain and can angle the tank over the drain, go ahead and do that now. Once the tank is empty, it is time to tighten your fittings.

Fixing the Problem

Assuming this is a fittings or valve problem, loosen any fittings that appeared to have leaked, repair the plumbing thread and retape the pipes, finally tightening the fittings back into place. The pressure valve may need to be replaced as well – do this now if it is necessary.

Before reapplying the electricity to the water heater, reattach the water supply and turn it on to check for leaks. If it holds water, you are lucky and your water heater’s tank isn’t leaking. Reattach everything and turn it back on.

If you notice the leak continues, you should call ACI Northwest, as it is likely the glass inside your tank has cracked or is leaking. Most of the time, this cannot be repaired and means you need a new water heater installed.

Heating Q/A: Why is my Air Handler Squealing?

Friday, March 16th, 2012

As a Sandpoint resident, do unusual noises ever come from your expensive heating system?  Do they make you worry that something is wrong?

It’s true that an unusual noise does often mean that you need heating system maintenance; however, a noise emanating from your HVAC system does not necessarily mean a major repair. You should always have a technician check out if you suspect a problem with your system, but not all problems are going to be expensive to fix.

One common noise that homeowners notice and complain about is a squealing noise originating in the air handler. Usually, this noise is coming from the fan belt that connects the blower fan and the motor. Over time, the belt can stretch out and become worn or misaligned, which makes it slip and generate that aggravating squealing noise.

So, while the squealing can be annoying and unpleasant, a slipping belt is by no means major. A belt is an inexpensive part and a technician can install it in just a matter of minutes.

As long as the noise is a squealing and not a grinding, this simple fix wil often take care of the problem. If you hear a grinding noise, however, immediately shut the unit down and call a technician. This may mean that your motor bearings are worn out and need to be replaced ASAP before further damage is inflicted on the motor itself.  Call ACI Northwest with any questions about your heating system.

Getting a Heating Upgrade? Consider an Energy Audit First for Your Bayview Home

Wednesday, March 7th, 2012

Are you considering a heating system replacement for your Bayview home?

Good for you! After all, it’s usually a sound investment that generates savings both in heating costs and repair bills, plus it keeps your family happy and comfortable.

Before you take the plunge on new equipment, though, you may want to get a home energy audit. What you find may help you choose the right system or even decide you don’t need to make the leap after all.

A home energy audit is essentially an inspection by a professional of the materials used to insulate your home. This includes not just the insulation in the walls, but also the walls themselves, along with windows, doors and so on. The idea is to figure out how much heat is escaping your home to the outside, so an audit may also include looking at ducts, vents or anywhere else where air could flow through.

So what does an energy audit have to do with a heating upgrade?

Think about it like this. There are two ways to make your home warmer: increase heat gain (e.g., get a more efficient heating system) or decrease heat loss. If you are able to do the latter, you may find that the former is unnecessary.

For example, you may get an energy audit and discover that by installing new windows and resealing your doors, you can increase heating efficiency by 10%. This could have big implications for your decision to get a new heating system, as you may decide that you can save money by getting a smaller capacity furnace.

You may even realize that you no longer need a new furnace at all!

Of course, you may still need a new heating system regardless. This is possible, but if it happens, so what? You have lost nothing by getting the audit — and you may have learned something about your home’s efficiency — and you wind up with the new system you were going to buy anyway.

Either way, a home energy audit is a diligent first step in upgrading your home’s heating efficiency.  To lean more call ACI Northwest

What is Involved in Replacing an Old System in Colburn?

Tuesday, February 28th, 2012

When your HVAC system starts to fail in Colburn — or if it already has — your options essentially come down to two: replace or repair heating the system. There are a lot of factors that go into making such a decision, but in general, if it is a newer system with a small problem and you haven’t had much trouble with it, then a simple repair clearly makes sense.

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 heating 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?

Wrong. There is a lot more to an 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.
  • Furnace registers or ductless mini A/C units.

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, 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.  Please call ACI NW with any questions.

Does Humid Air Affect How The AC Runs in My Home?

Wednesday, February 22nd, 2012

As a Spokane County resident you’ve probably heard a dozen times that humidity is removed by air conditioning. Unfortunately, the common assumption is that there is no inherent cost in allowing humidity to persist in their home. But, did you know it costs significantly more to remove humidity from the air with air conditioning than with a dehumidifier? Here’s why.

Water Vapor in Your Air Conditioner

Consider the amount of energy it takes to raise the temperature of water by one degree – one BTU. However, to change water from liquid to steam, another 10 BTUs are required. So, imagine how much energy it takes to condense water vapor from the air (in the form of humidity) into a liquid. This is what your air conditioner does whenever it processes humid air. It takes about 1,050 BTUs to condense one pound of moisture in the air into liquid.

The cost of running your air conditioner strictly for dehumidification can be huge, especially considering the fact that humidity is heaviest in the morning and evening when you probably don’t need your air conditioner every day (at least not early and late in the summer). Imagine, the cost difference if you used a dehumidifier to remove 150 or more pounds of moisture per week and an air conditioner when needed just to remove 15-20.

Negative Impact on How it Runs

Another thing to consider is that humidity can actually put an extra burden on your air conditioner. While the system is designed to remove that liquid from the air and get rid of it through the cooling coil and condensate drain, every extra minute the system is running is a bigger burden on it. Of course it will do its job for a few years, but the extra running time will add up, not only on your electricity bill but eventually on the machine itself.

The added pressure will result in eventual breakdown of the system and a need for early air conditioner replacement. The easiest solution is to purchase a dehumidifier. These run at a fraction of the energy level of a full AC system and work extremely well to remove humidity from your home. In fact, most air conditioners will only remove humidity after 20-30 minutes of continuous operation. For short cooling cycles, you may not even dehumidify the house. So a dehumidifier ensures higher levels of comfort all at a lower cost.  Please contact ACI NW if you have questions about this.

Common Air Conditioner Problems in Airway Heights

Friday, February 17th, 2012

Air conditioners are an important part of our lives here in Airway Heights. They keep us comfortable despite overbearing heat and humidity outside all summer, but because they run constantly for months and because they are such complicated pieces of machinery, they are prone to a number of problems. Here are some of the most common problems you’re likely to run into with an air conditioner and how to solve them:

Leaks

A common problem that many people ignore or are unaware of is refrigerant leakage. It is possible that when the system was installed, it wasn’t properly charged, but most of the time if your system is low on refrigerant, it is because of a leak. You can’t just pour more refrigerant in and call it good, though.

The leak needs to be fixed, both for health and environmental reasons. If you notice that your system is low on refrigerant or you smell something off – often like acetone, call a professional immediately for inspection and repair.

Sensors

An air conditioner doesn’t do you any good if the sensors don’t work properly. Improperly working sensors will fail to properly read the temperature in the home or from your thermostat. So, it might be 80+ degrees in your home but if the thermostat reads it as 72, the system won’t turn on. The air conditioner itself probably still works fine, but unless it can successfully read the temperature, you won’t get the cooling you need to stay comfortable.

Check first to see if the sensor was moved or knocked toward the evaporator coil (which will keep the temperature reading low).

Drainage problems

Your air conditioner acts as a dehumidifier as well, producing a liquid known as condensate. This liquid usually drains from the air conditioner into a designated area away from your home. However, if the condensate drain gets clogged or if the system wasn’t properly installed, that condensate can start to build up in your home. If you notice leakage around the coils, you may need a pump to remove the condensate properly.

Properly maintaining your air conditioner can usually be done with regular maintenance each year, but if one of these problems pops up, call a professional and get them fixed right away.  If you have any questions about this please contact ACI NW.
