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!

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.

Will Switching to Geothermal Heating Save Me Money?

Monday, January 9th, 2012

There are simply a ton of different types of heating systems available for your Colton home and they are each more appropriate in different situations. However, some are certainly always going to be cheaper to operate than others, although that alone may not make one or the other right for you.

In the case of geothermal heating systems, the operating costs are definitely quite low. But those are not the only costs you will have to think about when you are considering what type of heating system to put in your home to keep your heating bills down.

Geothermal heating systems do not actually generate heat – they absorb it from the ground. Because of this, they actually use very little energy when they are running. All you are really paying to power is the fan that blows the heated air around your house. Also, because geothermal heating systems are more efficient at extracting heat in below freezing conditions than traditional heat pumps, they can continue to keep you warm on their own in more extreme conditions.

Traditional heat pumps, while they also cost very little to operate, do sometimes need to be supplemented by more conventional forms of indoor heating like a furnace when temperatures outdoors get too low. This is not the case with geothermal heat pumps, so if you live somewhere that has colder winters, a geothermal heat pump may be just what you are looking for. Of course, you can always opt for a furnace instead, but these will definitely cost more to run than either type of heat pump.

When you are trying to assess whether or not switching to a geothermal heating system will save you money, you first have to start with the heating bills you currently have. Then, factor in the cost of the geothermal heat pump installation as opposed to the installation of a more conventional system.

You are then in a position to see whether or not the amount the geothermal system will save you each month is enough to offset the higher cost of installation within a reasonable amount of time. Of course, the savings will always eventually add up over time, but if the length of time it will take you to break even is the same or longer than the expected life of the system, it is probably not worth it to invest in this type of heating.

How to care for your heat pump filter

Wednesday, January 4th, 2012

On the whole, heat pumps are efficient, durable and effective to have in your Estacada home. They are built to run all year round without needing any more maintenance than your average furnace or air conditioning system and they have an average lifespan comparable to those other types of home comfort systems as well.

That’s not to say that there aren’t things you can do to keep your heat pump in good working order, however. Keeping up with the professional maintenance visits is an important step to take along these lines to be sure, but there are also some other things you can do on your own as well to help ensure the continued efficiency and health of your heat pump system.

Proper filter care is an important part of keeping your heat pump working the way it should. If you don’t have a heat pump yet but are thinking of getting one, make sure you have the installation technician show you where the filter is located and how to replace it.

If your system’s already been in place for some time, you can still find out how to care for the filter from your annual maintenance technician or you can probably even find it on your own by taking a close look at your heat pump. The filters are meant to be removed on a regular basis so they’re typically not hard to get to. However, you should always be sure that all of the power to your heat pump is turned off before you open it up to try and find, replace or clean the filter.

Most heat pump filters are meant to be changed or cleaned about once every 90 days or so. However, the specific requirements for each system can vary considerably, so you should be sure to find out what is recommended for the model of heat pump that you have.

Also, you’ll want to know what type of filter you have so that you can purchase the appropriate replacement. The model number for each filter should be clearly printed on it, so simply slide your current filter out and make note of the number so that you can purchase the correct type as a replacement.

Most heat pumps have replaceable filters, but some still do have permanent filters that are meant to be cleaned and then returned to service. If you have one of these types of filters, be sure to read the instructions for cleaning carefully before proceding.

What to Expect in a Low, Medium or High Efficiency Furnace

Friday, December 9th, 2011

When buying a new furnace in Eagle Creek, you have many options. You can purchase a low end model to save money up front and you’ll still get exceptional fuel efficiency, but as you go up the scale, more innovative, money saving features become available. Here is a brief look at what you can expect based on which type of furnace you purchase.

Low Efficiency Furnace

This is a bit of a misnomer as even entry level furnaces have efficiency ratings of at least 80%. For comparison, if you’re still using an old gravity furnace, your efficiency rating could be lower than 50%. Modern furnaces are built to conserve, and while you won’t receive all of the bells and whistles that tend to accompany high efficiency models, you will get a durable, affordable furnace that will last for 10-20 years.

Medium Efficiency Furnaces

Furnaces in the mid-efficiency range have AFUE ratings of between 85% and 92% and are therefore significantly better than those in the entry level range. They also have some of the higher end features available in high efficiency models like programmability and the option for zone control. Because they are still mid-range, they are affordable without skimping too much on features too – a must for any homeowner wanting to save money on both ends.

High Efficiency Furnaces

The highest efficiency furnaces on the market are very different from those you would have purchased even just 10 years ago. Top end furnaces can carry AFUE ratings of up to 95% with a boat load of added features to conserve energy. These features include two stage gas valves so you can maintain a low BTU heating system for most of the year but crank up the heat when the temperature outside drops too low. They are also programmable, which allows you to easily change the temperature settings, fan speed and more from anywhere in the house.

And while they cost more to install, high efficiency furnaces use less energy over their lifespan, last longer and are more environmentally friendly than any other furnaces on the market today.

What kind of noise can I expect my heat pump to make?

Wednesday, October 19th, 2011

Whenever you’re looking into replacing your old home heating system or installing a new one in Canby, there are many different factors you’ll have to take into consideration. The amount of noise that the system you choose will make is certainly one of these. And in addition to the amount of noise that this system will make, you’ll also want to make a note of where the unit will be placed and so where the noise will be coming from.

While you may have had to worry a bit about the noise generated by heat pumps in the past, it’s not something you’ll have to take into consideration this time around. That’s because newer heat pumps are designed to be quieter than ever, providing the same heating and cooling power with only a fraction of the noise of some earlier models.

In fact, the only part of a heat pump that really makes any noise at all is the outdoor unit. Unless this needs to be located very close to your home or to a window of a room that you use often, chances are that you won’t even hear it at all.

However, if you live very close to your neighbors or don’t have a lot of outdoor space, you may have to put the outdoor unit close to the walls of your home. Even then, though, you’ll hardly notice the noise your heat pump makes. Years of research and redesigning have produced some of the quietest heat pumps yet and that’s what you’ll be buying if you’re in the market for one of these systems now.

Newer heat pumps have been tweaked and adjusted to minimize the amount of noise-generating vibrations they produce. In fact, you’ll probably find that most of these units make no more noise than your refrigerator. They’re efficient and quiet and can keep your home comfortable all year long.

Furnaces vs. Heat Pumps

Monday, October 10th, 2011

If you’re preparing to replace your existing heating system in Cornelius, you may very well be struggling with the question of whether to go with a furnace or a heat pump for all of your future home heating needs. Each of these systems have their own advantages and drawbacks, and once you’ve narrowed it down to one type or the other, you’ll still have a pretty wide variety of products to choose from.

Furnaces are still the most popular type of home heating equipment on the market. You can get furnaces that run on gas, oil or electricity, although gas furnaces are by far the most common type of furnace around these days. The latest models are extremely energy efficient, with AFUE ratings reaching into the high 90%s.

Like heat pumps, furnaces use ducts to transfer heated air throughout your home. They typically require regular maintenance once every year or two depending on the type of furnace you have, and they can be expected to last anywhere from 15 to 25 years when properly maintained. Most modern furnaces are also made to be compatible with a central air conditioning or cooling system as well.

Heat pumps, on the other hand, don’t generate the heat that they circulate throughout your house. Instead they are able to extract the heat from the air outside and pump it inside. This means that they use much less energy than even the most energy efficient furnaces.

However, heat pumps are only capable of heating your house comfortably when the outside temperature is above freezing. If you live in an area with particularly long and frigid winters, you’ll probably find that you need to supplement your heat pump with another heat source. Because of this, it actually makes little sense to use a heat pump in more extreme climates.

On the other hand, if you live in an area with relatively mild winters, heat pumps can be a great option. They provide a constant flow of warm air to all parts of your home and can also keep you house cool during hot summer months. To cool your home, heat pumps simply reverse the process they use to warm it. They take the heat out of your indoor air and pump it outside. This is a very effective home cooling method and makes heat pumps a great solution for year round comfort.

How to Maximize Savings in Your Home

Wednesday, October 5th, 2011

When you are thinking about different ways you might be able to save money around your Welches house, the tendency is to think big. Maybe you need to upgrade to a more energy efficient furnace, or it could be time to install a new central air conditioning system. Maybe it is even a good idea to switch to solar or geothermal power.

But before you do any of that, you may want to try some quick and easy ways to save money around the house with the equipment you already have. Here are 8 great ways to cut your power usage and keep those energy bills down without investing a lot in new equipment.

  1. Seal Up Your House – No matter how energy efficient the heating and cooling systems are in your house, you will be using more energy than necessary if your house is not tightly sealed. Make sure there are not cracks or places where drafts can get in and you will start saving money right away.
  2. The Right Thermostat Setting – Are you really going to notice the difference between 72°F and 69°F? Probably not, but you will save about 3% off of your monthly heating bill for every degree you turn the thermostat down. The same goes in the summer too, just backwards.
  3. Programmable Thermostats – And while we are on the subject of thermostats, it is a good idea to invest in a new one with programmable settings. That way you will be able to set your house to be warm when you will be there and you do not have to pay to keep it warm all day long if it is empty.
  4. Ceiling Fans – Ceiling fans can help keep you cooler in the summer and warmer in the winter. Plus, they cost very little to run so they are a great investment.
  5. Light Bulbs – Switching to energy efficient fluorescent bulbs all over your house will save you a ton even though they cost a bit more to begin with.
  6. Lights Out – But energy efficient bulbs will only get you so far. You should also be sure to turn off the lights in any room you are not using.
  7. Power Strips – Many home appliances draw a small amount of power even when they are not turned on. Use a power strip to easily cut the power to them completely and eliminate that drain.
  8. Sealing Windows – Plenty of air can come and go through your windows as well. Upgrading to more energy efficient windows is certainly an option, but you can also help to seal up your home inexpensively by covering your windows with plastic.

Help your system last longer by scheduling regular maintenance

Monday, October 3rd, 2011

While every new furnace sold comes with a limited 10 year warranty for the unit and parts, it is a good idea to supplement your warranty with a more complete maintenance agreement with your Molalla HVAC provider. Why pay for a secondary maintenance plan when you already have a warranty?

For the most part, the limited warranty provided by the manufacturer is meant to cover things like faulty parts, abnormal breakdowns or recalls. If your system simply needs to get a checkup because you use it a lot or there is a clog that isn’t caused by the actual furnace or air conditioner, you will likely end up paying the maintenance cost. So, by paying for an upgraded service plan, you cover all potential breakdowns and you’ll never again need to worry about your system. It’s like getting the upgraded warranty for a new car that covers everything from a busted crankshaft to old windshield wipers.

Help Your System Last Longer

Another benefit of a maintenance agreement for your HVAC system is that the system lasts longer when it is regularly maintained. This will ensure your HVAC system lasts significantly longer than if you were forced to wait until you could afford an extra visit from your repair man.

So, not only do you ensure your system keeps working, you add a lot of valuable years to its lifespan. Imagine how much money you’ll save if your furnace or air conditioner lasts for much longer than advertised. Any breakdowns after the 10 year mark would require hefty repairs or replacement since your warranty is expired. So, it’s in your best interest to keep your system running smoothly throughout its lifespan.

Ultimately, an HVAC system is only as good as what you put into it. If you’re careful about your investments and are willing to spend a little extra now, you’ll stand to benefit far more in the future from a smoothly operating, efficient heating system.
