Why is My Central Air Conditioner Making Noise?

Monday, July 16th, 2012

A good air conditioner is a life saver in the midst of a hot and sticky summer in Portland, but just because the system makes you comfortable and makes the hottest months bearable doesn’t mean you want to hear it clanging and banging all summer. If you notice excess noise coming from your air conditioner, it might be a problem that can be fixed by your technician. Here are some common causes of excess noise from an air conditioner and what you can do to fix them.

  • Blower – The blower is a motor and fan blade assembly. If the blade touches the housing or if the motor needs a tune up, it might start to make excess noise. Loose screws, foreign objects, or a need for oiling or new parts will all cause noise problems but they are all easy fixes for a Portland AC professional.
  • Ductwork – If the sounds you’re hearing are in the ductwork or vents, it may be due to expansion and contraction in your ventilation system. This is normal and while it may be obnoxious, it tends not to persist during the hottest months as temperature won’t fluctuate as much.
  • Bubbling Sounds – If you hear a gurgly or bubbly noise coming from your indoor unit, it may be due to a blockage in the condensate line. The easiest solution is to have technican clean the condensate line and check for any clogs or blockages in the system.
  • Clicking Sounds – If you hear a clicking sound, it is likely from the relay or contactor in the system. If this is the case, have a professional check it right away. Electrical problems are not to be taken lightly where your air conditioner is concerned.
  • Foreign Objects – Sometimes, the condenser fan will make a lot of loud noise because foreign objects get stuck in there. Sticks, leaves, toys, food from small animals – it can all get stuck in the fans and make a tremendous amount of noise. Keep the area around your condenser unit clear of debris and check it often if you hear loud noises.

Most noises from your central air conditioning unit are explainable and can be fixed relatively easily. If you cannot find the source of the noise, however, and it is only getting worse, call the Clean Air Act Inc. before the problem grows.

Cooling Coil or Evaporator Coil Diagnosis & Repair for Air Conditioners

Monday, July 9th, 2012

Inside the air handler of your Portland air conditioning system is a cooling coil or evaporator coil. From a home cooling perspective, this is where the magic happens: where the actual cooling occurs. So, if there is a problem with the cooling or evaporator coil, you will notice a decrease in the performance of your AC system.

You may notice that the air flow has slowed significantly or even stopped, even though you can hear the air handler running. You may also notice that the air isn’t as cool as it used to be or should be. Aside from having a house that is not cool enough, this can also cause problems like high electricity bills or damage to other parts of the air conditioner. Use this quick guide to start diagnosing and repairing the problem.

Diagnosis

For starters, just try to get a good look at the cooling coil. Some problems are obvious enough upon visual inspection that no further diagnostics or major repair is necessary.

If you are able to see the cooling coil, look for things like:

  • Dirt and debris
  • Mold
  • Staining that indicates a refrigerant leak
  • Ice or frost
  • Damaged fins on the coil

Repair

Any of these could be the culprit that is degrading the performance of your Portland AC system. Some of these you can take care of pretty simply on your own – if there is obvious debris that you can remove safely, do so – but for most repairs you will want to call in a licensed technician. Especially if the problem is something potentially hazardous like mold growth or a refrigerant leak, you don’t want to take the risk. Let a professional from Clean Air Act who is trained in safely and effectively repairing the problem take care of it, so that your home can be comfortable again.

What Does Professional AC Maintenance Include?

Monday, June 25th, 2012

Besides the cool air, what we like most about our Portland air conditioning is that we don’t have to do anything to still live in a cool climate when it’s boiling outside.  With programmed thermostats adjusting the temperatures automatically, we don’t even have to turn it on.

Therefore, it is very inconvenient (not to mention uncomfortable) when our unit misbehaves and forces us to pay attention.  Our first inclination, suddenly over-heated,  may be to call for help, but often the repair can be accomplished easily or avoided completely by checking the drain line that may be clogged.

When it gets more complicated, it is important to consult a Portland air conditioning professional.

Air Conditioning 101

Air conditioning is a process which involves the rapid evaporation and condensation of chemicals called refrigerants, compounds that have properties allowing them to change from liquid to gas and back again at low temperatures.

Simply stated: when the liquid evaporates and transforms into gas it absorbs heat.  Compressed tightly together again, the matter condenses back into liquid with a residue of unwanted moist heat that must be released to the outdoors.  Over the course of handling the air to cool it, air conditioners are able to filter dust and dehumidify the air as well.

Annual Service

Air conditioning units are designed to last for a decade or two of virtually trouble-free comfort, so long as they are maintained regularly.  A service contract with a reputable company ensures reliable maintenance and establishes a relationship so that if anything should go wrong, your call for help will be at the top of the list with a mechanic who likely knows the details of your particular unit.

Annual maintenance includes:

  • a check for the correct amount of refrigerant in the system;
  • a pressurized system test for any leaks using an actual leak detector tool;
  • a controlled evacuation and disposal of any excess refrigerant instead of an illegal toss in the dumpster;
  • a check for and seal of any duct leakage within the in central systems;
  • a measure of air flow through the evaporator coil;
  • a verification of the correct electric control sequence, making sure the heating and cooling systems cannot operate simultaneously;
  • an inspection, cleaning and maintenance of the electric terminals and applying a non-conductive coating if necessary;
  • a check of all belts for tightness and wear;
  • a check for oil in the motors;
  • a check for the accuracy of the thermostat.

To schedule your maintenance appointment today, give Clean Air Act a call!

The Most Effective Environmentally Friendly Heating Methods

Monday, April 9th, 2012

Protecting the environment is a priority for many homeowners these days. The problem is that it can’t be as a high a priority as your heating system in Portland home. Sure, you want your home to be environmentally friendly, but you need it to be warm.

So, it seems you are forced to run your electric or high efficiency furnace as much as is necessary and hope that it’s not too much for the environment — or your wallet — to take.

Beyond the traditional heating methods of electricity, gas, oil and what have you, there are some alternatives out on the market these days that can keep your home warm while also being green.

Geothermal

One solution is geothermal heat, which harnesses the natural heat of the Earth to warm your home. Pipes filled with coolant run through the ground outside your home, absorbing the warmth of the Earth. Then, the warm coolant is pumped into your home through a network of pipes that radiate heat.

This method is effective and requires no additional fuel or energy.

Micro Combined Heat and Power (MCHP) Systems

Relatively new to the game are so-called MCHP systems. These heating systems have on-board power generators with high-efficiency computer modules attached. The power module interfaces with the thermostat, calling for heat when necessary. That activates the generator system, which quietly and efficiently generates all the necessary power to run the heater.

These systems are incredibly efficient and can slash the cost of your heating bill. As an added benefit, they continue to work during power outages, which has obvious utility in areas that experience harsh winter storms.

Solar

Then, of course, there is the most obvious and readily available source of heat to the whole planet: the sun. Solar heating systems can be either active or passive, which essentially just depends on whether additional specialized equipment is to be installed.

Obviously, solar heating systems are a better choice for areas that get a lot of sunlight year round.

Whichever environmentally friendly heating solution you choose, they have the added benefit of lowering your heating bill, which is always welcome.  Call Clean Air Act if you have any questions

How to Install a Programmable Thermostat in your Home

Friday, February 3rd, 2012

Programmable thermostats are one of the best ways to save on heating costs, especially if you have a hard time remembering to turn down the heat in your Hubbard home. Installing a programmable thermostat will allow you to set the times you want the heat turned up or down. Not only will this make heating your home more consistent and save energy, but it will also allow you to tailor your heating needs to your schedule.

For instance, you can set the thermostat to turn on before you get up in the morning so that the house is already warm when you get out of bed, and conversely, set it to turn down after you go to bed or leave the house for work. Depending on the brand and setting options, programmable thermostats are relatively inexpensive and easy to install.

Although all styles are slightly different, here are some basic instructions that show you how easy it is to install a programmable thermostat.  Remember, this is only a general guide; always check the instructions inside the packaging of your new thermostat before you install it, or check with an electrician.

1. Remove the Old Thermostat

Before you remove the old thermostat, check to see where it’s mounted. If it’s mounted to an electrical box, the voltage used to power the old thermostat may not be compatible with the new one. Ask a certified electrician or heating technician if you aren’t sure.

CUT THE POWER TO THE HEATING SYSTEM TO AVOID ELECTRIC SHOCK. You should always turn off the main power supply to your heating system before installing any new thermostat. If you aren’t sure how to do this, ask your HVAC contractor. Once you unscrew the mounting plate for the old thermostat, just unhook the wires. Don’t throw an old mercury controlled thermostat. You should ask your local waste management facility how to properly dispose of mercury products.

2. Locate all Wires

Wrap the loose wires around a pencil to keep the wires from falling back into the wall. Identify and label each corresponding wire with a letter (do not use color coding since this is not always accurate). Strip the plastic off the ends of the wires about ¼ inch if you need to.

3. Install and Insulate Wallplate

If the area around the new wallplate is larger than the plate, insulate the hole with non-flammable insulation. Take the wallplate off the programmable thermostat and hold it against the wall to mark the screw holes with a pencil. Pull the wires through the large opening at the bottom and screw the plate to the wall.

4. Wiring

Make sure you are comfortable with wiring before you attempt to do any electrical installations. Check the manual for your programmable thermostat for instructions on wiring that specific model. In general, you’ll want to make sure you match the wire labels with the corresponding terminals on the thermostat. Sometimes there will be extra wires that aren’t needed. Always test it before completing the installation. Don’t forget the battery!

5. Install the Faceplate

Once you have it wired correctly, all you need to do is align the brackets on the faceplate with the corresponding slots on the wallplate and fasten the faceplate to the rest of the mounting. Lastly, tighten the screw at the bottom of the thermostat to hold it in place.

If you have any questions regarding programmable thermostats, give The Clean Air Act a call.

Rhododendron Heat Pump Question: When Do You Need a Backup Heating System?

Friday, January 27th, 2012

A backup heating system is sometimes necessary for Rhododendron homeowners who heat their homes with an air-source heat pump. This style of heat pump transfers the heat from the outside air to your home in the winter, and it pushes the warm air outside the home in the summer. Although some systems are efficient enough to work in colder climates, most heat pump systems require a backup heater when temperatures drop below 20° F.

Furnaces are commonly used as a backup heater for air-source heat pumps, especially since the furnace fan blower can help distribute the hot air throughout the home. Although they are more expensive to buy and install, geothermal heat pumps typically do not require a backup heating system. These are also called ground-source or water-source heat pumps since they draw in heat from the ground below the house or from a nearby water source. Because they take advantage of the ground or water temperatures, they are also easier to maintain and have lower operating costs.

Getting the most cost-efficiency from a geothermal heat pump will depend on several factors, such as the size of your property, the temps of the subsoil, and access to local water sources. You will most likely not have to install a backup heating system with a ground-source or water-source heat pump; however, it is important to think about the installation costs and the variables that need to be in place before deciding on this type of heat pump.

Absorption heat pumps use a heat source, such as natural gas or solar-heated water, instead of electricity. Natural gas is typically used for absorption heat pumps, so they are also called gas-fired heat pumps. Depending on the source of the heat, you may or may not need a backup heating system. It’s always best to speak to a professional heating and cooling contractor if you are not sure when it’s necessary for a backup heating system.

Call The Clean Air Act Inc. if you have any questions about a backup heater for your Rhododendron home.

Comparing High-Efficiency and Mid-Efficiency Furnaces

Friday, January 13th, 2012

Whenever you are in the market for a new furnace for your Hubbard home, there are many models to choose from.  Many of the furnaces manufactured within the last few years are high-efficiency furnaces with a high AFUE rating (AFUE measures the amount of fuel the furnace converts into heat). When people refer to a mid-efficiency furnace, they are usually talking about older furnaces.

Single-stage furnaces were considered to be an efficient heating system when they were manufactured, but compared to newer furnaces, they use up a lot more energy than they need to. Single-speed furnaces are designed to run at full capacity until the temperature inside the home reaches the thermostat setting. After they shut off, the home not only loses heat, but the furnace will also take longer and burn more fuel when it cycles on again.

Newer, two-speed and multispeed models run consistently at lower speeds, and the ones with variable-speed blowers are even more efficient because they can operate at various levels. These models will also automatically adjust to the thermostat to maintain a constant temperature, which saves energy by keeping the home at a consistent temperature so that there’s little heat loss.

When shopping for a new furnace, keep in mind that the AFUE ratings for multispeed and variable-speed furnaces only determine the efficiency of the actual furnace. If you are upgrading your old, mid-efficiency furnace to a high-efficiency furnace, you should make sure that your Hubbard home is properly insulated and sealed.  You could also consider upgrading any older doors and windows to more efficient double-paned ones, or you can also install storm doors and windows.

How to Fix a Faulty Furnace Blower

Monday, December 5th, 2011

The blower fan on your furnace is designed to distribute warm air through the ductwork in your Troutdale home evenly, ensuring you use all of the energy consumed by your furnace. If the blower doesn’t turn on when the furnace turns on or it continues to run when the furnace is off, it can cost you money and result in cold rooms. Here are some tips on how to fix a faulty furnace blower.

What is the Problem?

First, check to see what the problem is. If your furnace blower remains on all of the time, it may be a thermostat issue. Make sure the fan isn’t set to stay on continuously (a common setting for most air handlers). You should also check the limit control switch to make sure it is working properly. If this is broken, it needs to be replaced which is a relatively simple fix.

If the furnace blower isn’t turning on at all, you may have a belt problem. This can be fixed by you if you have the proper tools. To repair the belt problem, first turn off all electricity to the device. You’ll need to remove the old furnace blower belt, so release the tension in the pulleys before removing the belt.

Installing a new belt is not unlike doing so for your car. Make sure to check the blower or your user manual for proper tension when you install the new belt. Make sure you purchase the right size belt and set it to the right tension. If you cannot or you do not feel comfortable doing so, you should call a professional to inspect and repair the problem for you.

Getting the Blower Back Up and Running

Once your new belt is in place, test the system carefully, starting with the lowest setting (if there are variable settings). If it does not yet work or if something sounds strange, call a technician right away. You don’t want the motor to burn out or something else more substantial to go wrong with your furnace or air handler during the middle of the winter.

What Size Heat Pump is Right for My Home?

Wednesday, November 30th, 2011

One of the most important questions to answer when purchasing and installing any new heating or cooling system, no matter what type, is what size is best for your Sherwood home. You need something that has enough capacity to heat or cool your whole home comfortably; otherwise your house will consistently be at an undesirable temperature.

Some people might think that the quickest solution to this problem is to just buy a system that they are sure has a capacity larger than the size of their home. You may even be tempted to get the biggest model out there, under the logic that the biggest is the best and it will be sure to be able to cover your whole house.

While this line of thinking might make sense to you, it’s actually not a good idea. The problem with this “solution” is that you can wind up with a heat pump that is considerably too large for your needs, which means your home will consistently be either too cool or too hot, and your energy bills will be unnecessarily high.

The best way to choose a new heat pump is to have a professional do a load calculation in your home. This can be a highly technical process, so it is best to leave it to the pros. However, here are some quick tips and other things to consider on the subject:

  • There are a lot of variable to consider in doing a calculation like this. A contractor doing a load calculation will consider the type of construction, what kind of insulation you have installed, what kind of windows you have, whether there is an attic, how many people live there and many more factors.
  • It never hurts to shop around. Get a few estimates from different area contractors, rather than just going with the first opinion.
  • Also, since heat pumps are used for both heating and cooling, different contractors may opt to do the calculation in different ways. Some will estimate capacity based on heating, while others will base it on cooling. Ask to see which is the case for each estimate you receive.
  • If you are getting a new heat pump as a replacement for an existing one, or even a different heating/cooling system, check the capacity of the unit you are replacing. That can be a good place to start. You will at least be in the right ballpark.

All of this means doing some extra leg work up front, but getting the proper sized heat pump is well worth the effort.

What to Do if Your Heating System Breaks

Monday, November 21st, 2011

What if the heart of your Oregon City home’s heating system – the furnace – stops working? The warm air that used to flow from your vents has been replaced by a chilly draft. It isn’t time to panic, but it is time to take action. Before you do anything, determine why the furnace stopped working. It may be something as simple as a tripped circuit breaker in your electrical panel. Check the circuit breakers first.

The pilot light in your furnace may have blown out. It can be re-lit if you follow the directions in your furnace owner’s manual. You can find answers on how to re-light a pilot light on the Internet, too.

If the shutdown has not been caused by an electrical or pilot light failure, there is still no need to panic. But another obvious question is: did you pay your last gas bill? Maybe you had a shutoff notice and either ignored it or forgot about it.

Now that you are convinced that the furnace has pooped out, here are some things you should do. First, find the name of a qualified heating and cooling professional. If you already use a heating contractor, contact them and schedule a service call.

While you are waiting for help to arrive, ensure that everyone is safe and accounted for. Make sure pets are nearby and protected from the cold, too. What you don’t want to do is use any appliance to keep you warm that is not designed to keep you warm, like a stove. If you have electric space heaters or propane heaters, carefully locate them in a well vented room (windows open a bit or portable fans circulating air). You don’t want any build-up of gases from fossil burning appliances, gases which could contain deadly carbon monoxide.

Huddle up everyone into a room and break out lots of blankets. You may even want to make an “adventure” of this – find a movie to watch and pop up a bunch of popcorn.  If your waiting time is more than 24 hours, you might want to call up a friend or relative and make arrangements to spend the night with them.

The main thing to remember is not to panic. Most qualified heating contractors, knowing the circumstances, will send out a repair person in a matter of minutes or within one or two hours. Just remember to avoid keeping warm by using unvented heating devices.
