What Are the Advantages of a Maintenance Plan?

Monday, June 6th, 2016

Spring is rapidly turning into summer here in Tualatin, OR, and this is the time of the year that we strongly recommend an air conditioning maintenance session delivered by one of our trained technicians. They’re not quite the same as a repair session, which is designed to fix a specific problem. Instead, they check for any potential problems that may be brewing, as well as taking care of little servicing duties like changing the filters and tightening loose bolts and screws. That may not sound like much and the notion of an added expense might not sit well with homeowners already braced for the higher bills of summer. But there are considerable benefits to doing so, with both short-term and long-term implications for your system.  (more…)

Own a Mobile Home? Consider a Heat Pump!

Monday, April 4th, 2016

Spring has arrived here in Tualatin, OR, and summer will be here before you know it. That makes this an ideal time to install a new air conditioning system in your home. Mobile home owners usually content themselves with box-mounted air conditioning units and space heaters, but those are incomplete systems at best. A better option can be found with a heat pump, which uses the principles of air conditioning to both heat and cool your home. They make a good fit for our Oregon climate, with its cool-but-not-too-cold winters, and for mobile home owners interested in heating and cooling options would be well-advised to give it a look. Recent benefits have made the process of doing so even easier. (more…)

How Do I Determine the Cooling Capacity of My Central AC or Heat Pump System?

Monday, July 23rd, 2012

For any type of air conditioning system in Gresham, the cooling capacity is measured in BTU’s. This is important to know if the system doesn’t seem to be adequately cooking your home, and there are many different ways to check the cooling capacity of your AC system.

1. Air Conditioning System’s Age and Serial Numbers

An air conditioner’s age will usually give you a general idea for its cooling capacity, and if you aren’t sure, you can always check the serial number. Because serial number formats vary by the year the equipment was made, you can check to see how old an air conditioner is from looking at the serial number.

The first four digits of every serial number is the week and year the unit was manufactured.  For example, the serial# 1188E53294 on a compressor unit tells us that it was made between 1980 and 1990, and to be more exact, week 11 in 1988.

2. Air Conditioner’s Model Number

You should also look at the model number for your specific model because some manufacturers also vary how they assign each number in the serial number; however, they usually stand for tonnage or MBTUH. You can always call us if you aren’t sure how to read the serial number or model number.

3. AC Equipment’s RLA Numbers

RLA stands for “Rated Load Amps,” which means that it’s the manufacturer’s rate of the cooling capacity (also known as the draw) or load while it’s operating (minus the draw when you start the system). Most air conditioning compressor or condenser units will draw 5 to 6 RLA per ton of cooling capacity. You can check the data tag on the compressor for the RLA rating; however, this will need to be translated into BTUH for the total cooling capacity.

Feel free to call one of the Gresham air conditioning experts at Clean Air Act if you have any questions how to calculate your AC system’s cooling capacity.

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.

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.

Allergies – Products that Can Help with Air Quality Problems

Monday, January 30th, 2012

One of the biggest problems related to indoor air quality for Portland residents is allergies. When not treated properly, excess dust, humidity, bacteria, mold, and other contaminants can cause a number of allergy problems, especially if anyone in your home has asthma and is particular sensitive to a contaminant.

Luckily, there are quite a few products on the market designed to reduce the effect of indoor allergens and help you feel comfortable all year long.

Air Cleaners

HEPA Air Cleaners are designed to capture incredibly small bits of debris in your home. They remove things like dust, mold, debris, pollen, and pet dander before they can trigger an allergic reaction. The best filters are all HEPA certified and are available either for a single room or for your entire home. The size of your home and the amount of contaminants you have will ultimately determine which filter is best for you.

Purifiers

For those with allergens beyond dust and pollen, purifiers are a good next step. Air purification is done electronically, utilizing ionization technology to remove things like gas and smoke as well as bacteria and viruses that get into your indoor air. Anyone suffering from even a mild bout of seasonal allergies can be made very uncomfortable by these types of contaminants. Advanced purification systems also come with UV germicidal lights to kill bacteria and viruses.

Ventilation

While capturing the bad stuff in your air is important, so too is getting new air into your home. Allergies are triggered as much by stale air as by the allergens in it. So, a good ventilation system is important. Simple fan units work very well for many families, but if you want to avoid the loss of heated and cooled air during the most extreme weather in your area, an energy recovery ventilator is a good alternative to straight fan ventilation.

Humidity

Finally, humidity is a big issue for many families. Dryness in the winter can make colds and flus worse and excessive humidity in the summer is a haven for things like mold. A good humidifier removes humidity when it gets too high and adds moisture to the air during the winter when it gets too dry.

Always do your research before choosing an air quality system for your home. It’s important to choose components that will help you overcome whatever allergies you face, throughout the year.

How Does Geothermal Energy Work?

Wednesday, January 11th, 2012

Geothermal energy is energy extracted from the ground. This energy is in the ground in the first place because the ground absorbs the heat coming from the sun. This heat is always there, even when it is very cold outside. In fact, even when the ground appears to be frozen, you can actually extract plenty of heat to keep your Tualatin home nice and toasty.

While this may at first appear to defy logic, the way that geothermal energy can be used for heating your home is actually quite simple. A geothermal heating system typically consists of an indoor air handler with a fan, a series of air ducts for the heated air to travel through and a closed loop of pipe that extends into the ground below and around your home.

This closed loop of pipe is actually where the geothermal heat is collected. Some type of liquid, usually water or antifreeze, will be continuously run through this pipe loop. As the liquid passes through the area of pipe that is below ground, it will absorb the heat from the surrounding soil. Once the liquid makes it back up to the air handler, the heat is able to disperse, heating the air in the chamber.

This heated air is then circulated throughout your house through the ducts by a fan. After it has released its heat into the air in your home, the liquid will cycle back into the ground to absorb more. This allows a geothermal heating system to provide you with a constant supply of warm air.

Unlike a furnace, which mixes in blasts of very hot air with periods of inactivity to try and keep your Tualatin house at a constant temperature, a geothermal heat pump is able to provide a more consistent flow of air that is just the right temperature to keep your home comfortable. This means that these types of heat pumps are running just about all of the time as opposed to furnaces, but they are designed to work this way and the constant operation does not cause any excessive wear and tear.

Another great benefit of geothermal heat pumps is that they are able to keep your house cool in the summer as well. Just as the ground is warmer than the air in the winter, it is also cooler in the summer. That means that heat removed from your indoor air can be transferred to the ground in the same way that it was transferred in during the winter.

HVAC Maintenance the Whole Family Should Know

Monday, November 14th, 2011

If you think the most important thing a heating and cooling (HVAC) system can do is to provide an comfortable environment in your Cornelius home, you are right. But there is another thing an HVAC system does that is very important and it affects your entire family. It provides a safe indoor environment, too.

Besides warmth in the winter, a finely-tuned HVAC system can clean and filter the air you breathe. That’s important to people who suffer from allergies and is especially important for minimizing the spread of germs that cause colds and the flu. The key phrase in this paragraph is finely-tuned. If your HVAC system is not working correctly – out of tune – it can cost you a great deal in monthly utility bills and can be harmful to your health.

It is important for you and your family members to understand the basics of HVAC system maintenance so you can all understand the symptoms of improper maintenance and its consequences. For example, if anyone in your home is suffering from flu-like symptoms or are constantly drowsy or listless, they may be suffering from the a silent killer: poisonous carbon monoxide gas. This gas is formed during incomplete combustion of fossil oils like natural or propane gas. A malfunctioning furnace can emit carbon monoxide gases and you may never even realize it, until it is too late. Long-term exposure to the gas can cause brain damage and/or chronic sleepiness. It some cases, it can even cause death.

You may be able to diagnose the problem, but you aren’t qualified to test and repair a furnace that is creating deadly carbon monoxide gas. Your best bet is to call a qualified HVAC contractor who can diagnose the furnace and offer repair or replacement suggestions. But there are things you can do to prevent the build-up of carbon monoxide gas.

Check all exhaust vents, like chimneys and flues for any blockages. A blocked or partially blocked vent can cause the build-up of carbon monoxide gas. And never, EVER, use a gas or propane powered heater in an unvented area of your home. These types of heaters create various levels of carbon monoxide gas that needs to be circulated out of each room and replaced with clean, fresh air. So, your family can actively ensure that there is no debris, bird’s nests, animals, leaves, or snow in the ventilation system.

You can also “help” your HVAC system by keeping vents clean by vacuuming dirty vent grilles and, in general, keeping the home clean. The cleaner the home, the easier it is for your furnace to do its job and the easier it will be for you and your family will breathe. These are a few easy maintenance tips will keep you and your family warm – and safe – this fall and winter.

What Is a Downflow vs. an Upflow Furnace?

Wednesday, October 12th, 2011

When you go looking to buy a furnace in Clackamas, you may well be surprised by how many different elements go into making a good purchasing decision. There are simply so many different kinds of furnaces available now and they each are more appropriate for certain situations. That means that finding the one that’s right for you is less about finding the one best unit than it is about finding the one that is the best match for your particular circumstances.

This applies to the type of fuel the furnace uses, its energy efficiency, and whether it’s an upflow furnace or a downflow furnace. Energy efficiency and fuel types are probably things that you’re more or less familiar with. But what are we talking about when we classify a furnace as an upflow or downflow model?

Well, it’s pretty much what it sounds like. These terms refer to the direction the air flows as it is taken in and heated by the furnace. So in an upflow furnace, the cool air is taken in at the bottom, warmed, and then expelled at the top. A downflow furnace, on the other hand, takes in cool air at the top and expels heated air at the bottom.

While this is all very exciting, it may still not be obvious what impact this will have on your decision about what type of furnace to buy. The main thing you’ll have to think about when you’re deciding between an upflow and a downflow furnace is where the furnace will be placed in your house.

An upflow furnace is generally installed in the basement so that the heated air is directed towards the parts of the house you want cooled and so that the furnace can be appropriately vented outside of the house. On the other hand, a downflow furnace would be installed in your attic for the same reasons.

So where you want to have the furnace installed is probably the biggest thing to take into account as you’re comparing these two types of equipment. Of course, whether you pick an upflow or a downflow furnace, you’ll still have to select the appropriate AFUE, size and fuel source to best meet your needs. But making the choice between upflow and downflow can at least make it easier to narrow down your options.

4 Ways to Improve IAQ and Reduce Air Pollution

Friday, September 23rd, 2011

Your Gresham home could be  a haven for pollutants that can cause irritation to the upper respiratory system of anyone who comes inside. These allergens and pollutants are easy to remove however by taking some simple steps such as the four listed below:

  1. HEPA Filtration – Step one is to use HEPA filtration to remove as much of what is on the floor as possible through vacuuming. HEPA vacuum cleaners can remove years of cleaners, solvents, dander, mineral build ups and other toxins that tend to accumulate in spaces that normal vacuums cannot reach. It may be a bit of an investment, but a high powered vacuum cleaner can have a tremendously positive impact on your lifestyle and reduce pollutants.
  2. Stop Outside Stuff from Coming In – Some of the worst pollutants your home will face are from outside. So, make sure you have doormats at every door and that your family and friends remove their shoes before coming inside. You can have a second mat inside as a friendly reminder that cleaning the shoes is not an option but a strict necessity.
  3. Humidity Helps – Humidity levels between 30% and 50% reduce the presence of dust mites, molds, bacteria and many other indoor pollutants. Air conditioning in the summer is helpful to reduce humidity, though a dehumidifier is recommended for those days when the temperature doesn’t justify full blown air conditioning. Additionally, look for sources of excess humidity like leaky pipes, standing water, or clothes drying.
  4. Cut the Chemicals – There are a number of high quality household cleaners that don’t contain chemicals. Avoid ammonia, bleach and other chemical laden cleaners that can inflame allergies and pollute the water supply. Your home will be just as clean and you won’t feel uncomfortable afterwards.

Proper cleaning and careful selection of compounds and what goes into your air will help you avoid creating new air quality problems in the house. Done right, this process will make everyone in your home feel more comfortable.
