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.

Crawlspace Heating Tips

Monday, February 13th, 2012

Keeping your crawlspace warm and insulated in Washington County might not seem like something that should be at the top of your priority list. However, if you really want to find ways to save money on your heating and cooling bills and keep your home as comfortable as possible, it’s definitely something you should look into.

The crawlspace of your house is generally located beneath the floor and since it’s not someplace that you’re likely to spend much time, it’s generally not insulated or sealed against the elements very securely. In some cases, heating and cooling ducts and pipes carrying hot water can run through the crawlspace as well.

The lack of insulation in the crawlspace of your house can impact your indoor environment in a couple of ways. First of all, it often means that your floor is cold to walk on and that cool air can seep in through any cracks there might be in your flooring. This infiltration of cooler air means that your home heating system will have to work harder to maintain a comfortable temperature inside.

Also, the air and water traveling through the ducts and pipes in your crawlspace will be losing heat as they go, so you won’t be getting all of the heat you’re paying for on that end either. Adding insulation in your crawlspace is the best way to keep from losing heat in this way. It’s generally not a huge investment and it will save you quite a bit in the long run. It can also help your heating system last longer because it won’t have to work so hard to keep your home warm enough.

If you live in an area with relatively mild winters and hotter summers, you might think that investing in some crawlspace insulation wouldn’t be worth it for you. But the truth is that you can save just as much by keeping your cool air inside in the summer as someone in a cooler climate can by keeping hot air inside in the winter.

And insulating and heating your crawlspace isn’t just about keeping the rest of your house warm. It can also help to keep moisture problems from developing. An excess of moisture in your crawlspace can quickly allow mold to develop and too little moisture is damaging to wood and can cause your heating system to function less effectively overall.  If you have any questions about these issues please contact Clean Air Act.

Heating Replacement Checklist: 5 Reasons to Replace Your Furnace

Monday, January 23rd, 2012

Many Estacada homes are heated with furnaces, since they generally provide safe and efficient heat.  Furnaces have also improved dramatically over the years as manufacturers find ways to make them more efficient. Even if your furnace has been reliable for many years, it may be worth the money to replace your old furnace with a newer, more efficient model.

Here are five major benefits to upgrading your furnace.

1. Lowering Your Utility Bills

Whether you realize it or not, your current furnace could be costing you more than it should in heating bills. If your furnace is 15-20 years old, it’s probably not heating your home as efficiently as the newer models with higher AFUE ratings. Even if your heating system has been replaced within the last ten years, the technology has advanced enough to consider an upgrade.

2. Fewer Repairs

Repair costs can add up if you are constantly repairing your furnace. Routine maintenance for your furnace can help reduce the need for repairs, but as furnaces age, they tend to need more repairs and replacement parts. If you need frequent repairs for your furnace, it may be time to replace it with a newer one.

3. More Consistent Heat

While maintaining consistent temperatures throughout your home involves several factors, such as insulation and thermostat control, your furnace could also be the reason you aren’t getting enough heat to all parts of the house. If some rooms are colder than others, or if your heating bills have recently gone up, it may be time for a furnace replacement.

4. Reduce the Chances of a Breakdown

When a furnace breaks down, it not only leaves you without heat, but it is also a major expense. Budgeting for a new furnace before it breaks down will put less financial burden on you than needing an emergency furnace replacement. Newer model furnaces are also more reliable and less likely to give you problems if maintained properly.

5. Safety

There’s higher potential for safety concerns with older or poorly maintained furnaces. In addition to fire hazards, carbon monoxide poisoning is another serious threat. When the heat exchanger stops working because it’s corroded or faulty, carbon monoxide can leak into the home. If you’ve had your furnace for more than 20 years, it could create safety hazards that you may be unaware of.

No matter how long you’ve had the furnace in your Estacada home, it’s always wise to speak with a qualified HVAC technician about furnace upgrades, particularly if you have expensive heating costs. Call The Clean Air Act Inc. today to talk with one of our heating experts about furnace upgrades.

Different Types of Furnace Maintenance

Friday, January 20th, 2012

There are different types of maintenance tasks associated with keeping your automobile in tip top shape. Did you also know there are tasks that can be performed at various intervals to keep your Happy Valley home’s furnace in peak running condition?

For example, the most frequent maintenance task is checking the filters in your air handling unit. These are often called furnace filters but in reality, they serve the same function to filter air to and from your air conditioner, too. It might be easiest to just call them air filters. The frequency of replacing or cleaning air filters usually depends on the type of indoor environment you live in – like humidity levels, number of household pets or occupants, etc. In general, filter maintenance should occur every one to three months.

A less frequent maintenance task is cleaning the moving parts of the internal mechanism. You may only need to have your furnace cleaned every six months to a year, depending on its use. In some cases you can perform the cleaning yourself or it is included in an annual cleaning as part of a service agreement with a qualified heating and cooling contractor. A furnace can typically run at peak efficiency when it is cleaned on an annual basis.

You can also make it a regular habit of checking the motor bearings and fan belt, too. You can lubricate the bearings and tighten or replace the fan belt on a same schedule as cleaning the moving parts.

Other maintenance tasks related to your furnace, which may require longer interval times include ventilation system cleaning, or more commonly known as duct cleaning. Some homes don’t require this type of maintenance more than every five to ten years – perhaps longer. Unless there are unusually high levels of dust, allergens, or contaminants in the air, most ventilation systems can remain clean for several years.

Of course, you can turn all of your maintenance tasks over to a Happy Valley heating and cooling contractor – and have the most peace of mind.

High Efficiency Furnaces and Chimney Concerns

Monday, December 26th, 2011

When upgrading to a high efficiency gas furnace in Portland, you may need to make some upgrades to your chimney. Older chimneys built for standard furnaces with normal exhaust needs are not built to the specifications needed by today’s high efficiency models. Not only is it unsafe to leave it as is, but the cost of repairs if you don’t have it upgraded can be substantial.

Down-Sizing

A common concern when upgrading to a high efficiency gas furnace is the issue of condensation and draft. Because the amount of exhaust being vented is reduced by a high efficiency furnace, your current setup is not sufficient for the new model. So, it needs to be reduced in size by a professional to avoid backup of exhaust. Proper chimney sizing is a complex process that requires professional guidelines and careful measurements of all appliances in your home.

Because the chimney often isn’t used at all for a high efficiency furnace (often PVC pipe used instead), the extra airflow in the chimney can become a major issue.

Chimney Condensation

The biggest concern for the chimney when changing the furnace efficiency is condensation. Specifically, acidic condensation droplets can build up in the chimney if not properly stopped. A new chimney liner must be placed in the chimney to avoid excessive corrosion due to the acid droplets. Keep in mind that the efficiency of your new furnace will determine whether you will use the traditional chimney for exhaust or if a new line will be installed to vent your furnace.

When to Take Action

If you have your furnace replaced, your technician will likely discuss the chimney situation in your home with you. Keep in mind that this might be necessary and that there might be an added cost involved because of it. Modern furnaces are not designed to accommodate aging chimneys and your safety and the integrity of your house are at risk if you don’t retrofit the chimney if necessary.

What Is an Air Source Heat Pump?

Monday, December 19th, 2011

Most heating systems have as their main component some sort of heat generator, such as a furnace. These machines generate heat through some form of combustion, which obviously converts energy directly to heat, which is then distributed throughout your Lake Oswego home. That’s a pretty simplified schematic explanation, but that’s more or less how most heating systems work.

Air source heat pumps are another type of heating solution; one that does not actually produce or generate any actual heat. There is no combustion. What an air source heat pump (ASHP) does instead is regulate the temperature of the home by essentially moving air around.

An air source heat pump use electricity to exchange indoor and outdoor air. Think of it like a more versatile air conditioner. In cooling mode, like an air conditioner, an ASHP will pump warm air from the inside out, using a system of refrigerant-filled coils and a compressor. By turning the ASHP to heating mode, the refrigerant flow is reversed, allowing the outdoor coils to extract heat from the outdoor air and pump it in higher concentrations to the inside.

If it seems like a simple system, that’s because it is. All the heat pump does is move heat either in or out, depending on what you need in the current season. Because this process generates no heat on its own, heat pumps can be very efficient. ASHP efficiency has been estimated at 150% to 300%, meaning that the heat energy produced is up to three times as much as the electricity used. That makes for a very efficient home heating and cooling solution.

Air source heat pumps are not necessarily right for every situation, however. In colder climates, where temperatures drop below 30 degrees Fahrenheit for stretches at a time, a heat pump will likely not be able to keep up on its own. In these situations, you may either need to supplement the ASHP with an additional heating source, or use a different system altogether. Newer so-called “cold climate” heat pumps may also be an option. Under ideal circumstances, an air source heat pump can act as a complete home heating system, as well as providing heat for hot water.

If you are looking for a simple and efficient home heating solution in Lake Oswego, look into whether an air source heat pump can work for you.

Signs of an Undersized Furnace

Friday, December 16th, 2011

If you’re purchasing a new furnace for your Sherwood home, you want to avoid buying one that is undersized for your particular space. To do that, here are some common signs that the furnace isn’t powerful enough for the heating needs of your home. These signs might appear for an older furnace as well, especially as it ages and loses its ability to provide adequate heat for your home.

Maintaining Temperature

The most common (and in many cases only) sign that your furnace is undersized is that the device simply doesn’t maintain the temperature in your home properly. This means that when turned on to full and left for a few hours, your furnace doesn’t heat your home to the thermostat setting.

This can be due to an improper load calculation or a load calculation that wasn’t taken at all. The perfectly sized furnace will heat your home evenly on the coldest day your area is likely to have. So, undersizing should be pretty evident – if it doesn’t heat your home evenly and it’s not exceptionally cold outside, you might not have enough BTUs under the hood.

How to Fix the Problem

The problem is one that varies depending on the severity of the undersizing. Modern furnaces are often available with two stages, meaning they can operate at both a low BTU rating (often around 40K or so) and a higher BTU rating (70K or higher). This is the perfect solution for homeowners worried about undersizing because it ensures that your home always has enough heat in reserve should the weather get exceptionally cold.

For example, most furnaces are sized for extremely low temperatures, but if the temperature jumps up to 50 degrees F outside, your furnace is now oversized for that weather. A two stage furnace offers solutions for both common conditions and extreme conditions and will resolve most of the concern you have about undersizing and not having enough heat to offset outdoor temperatures.

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.

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.
