Have you been hearing the term indoor air quality Vancouver or IAQ used more lately? The reason it’s a hot topic is because of how negatively poor indoor air quality can effect the health of your family. It is estimated that indoor air can be up to 70 times more polluted than outdoor air. With poor indoor air quality in your home, your family may experience exacerbated health problems such as allergies, respiratory issues and sinus issues. According to the EPA, Environmental Protection Agency, negative health effects may show up later with continual exposure. It is important to take the quality of your indoor air seriously before your family experiences negative health effects.

So what constitutes good indoor air quality Vancouver? According to the United States Department of Labor, “The qualities of good IAQ should include comfortable temperature and humidity, adequate supply of fresh outdoor air, and control of pollutants from inside and outside of the building.” In this article we will discuss ways to improve the indoor air quality Vancouver and over all comfort of your home.



The easiest way to improve your indoor air quality Vancouver is to change your air filters regularly. Your air filters should be changed every month to once a year depending on the filter type and how much dirt and dust the filter is collecting. To read more about filter sizes and types click here.


Air Purifier

The Protector, an air purifier, reduces mold, viruses and other contaminates in your home by 99% using NASA based technology. It also greatly reduces excessive smells in your home due to pets and/or smoking. After installing The Protector, these health issues may improve:


Duct Cleaning

Dust, dirt, mold and other contaminants build up within the ductwork of your heating and cooling system over time. These contaminants are then cycled through your home throughout the day, which can make existing health problems worse. We recommend getting your ductwork cleaned every 7 years by a professional.  We use the Rod-Whip method for our professional duct cleanings. This method thoroughly your entire duct work and leaves your home with hospital grade clean air.


Wi-Fi Smart Thermostat

Thermostats are becoming more advanced than ever. The new Wi-Fi smart thermostats, such as Lennox’s iComforS30, help to alleviate your allergies indoors and improve indoor air quality through pollen monitoring. When the pollen count is high outdoors, it automatically kicks on the fan on your HVAC system. In addition, these thermostats are programmable so you can set the thermostat to different temperatures throughout the day for your increased comfort. Often people will have it a different temperature when they are sleeping compared to during the day when they are active in the home.

heat pump Vancouver, air conditioning repair Vancouver

As summer approaches, it can be difficult to know whether you should replace your AC when handed an air conditioning repair Vancouver bill. You don’t want to invest money into a new system when your current system will last longer. Luckily there are five basic things to consider before deciding.


  1. Age of Equipment

If your AC is 12 years or older, it may be time to consider replacement. According to the National Association of Home Builders / Bank of America Home Equity’s Study of Life Expectancy of Home Components , you should anticipate that your air conditioner will last anywhere from 10-15 years. Miller’s Heating & Air offers free in home estimates on new equipment.

  1. Repairs

Air conditioning repair Vancouver can be costly and stressful. If the cost of the air conditioning repair Vancouver exceeds 50% of the cost of a new AC then it makes more financial sense to replace. An AC replacement can cost anywhere from $4,000-$7,000 depending on brand, sizing and efficiency.  Miller’s Heating & Air offers financing options on new AC systems. Learn more about your financing options by click here.

  1. Utility Bills

Are you noticing that your utility bills for cooling are noticeably higher or creepy up slowly? It may be time to replace your air conditioner with a more efficient newer system. As AC systems age, they become more inefficient due to dirt, lack of maintenance and normal wear and tear.  When you upgrade, make sure to look for an Energy Star rating on the equipment in order to get the most return on your investment. According to Energy Star, upgrading to one of their approved ACs can save you up to 20% on your cooling utility bills.

  1. New Technology

Heat pumps Vancouver are outdoor units similar to air conditioners except that they can heat and cool the home. They are energy efficient and last longer than air conditioners. On average a heat pump Vancouver last around 16 years while air conditioners last 10-15 years. Even if you decided to replace with a AC rather than a heat pump Vancouver, the newer AC models have advanced technology. This technology is more energy efficient and will increase your comfort in your home. Miller’s Heating & Air is your local AC and heat pump Vancouver expert with over 70 years experience!

  1. Environmental Considerations

The Environmental Protection Agency, known as the EPA, is phasing out substances and chemicals that negatively affect the ozone. One of these substances currently being phased out of use is R-22 refrigerant. R-22 is one of the most common refrigerants used to run ACs. By 2020 there will no longer be any production or import of R-22 refrigerant. Newer ACs are designed to run on a more environmentally friendly refrigerant called R-410A. It’s not a bad idea to consider replacing your old AC for one that runs on R-410A before the phase out is complete.

  1. Saves You Money

According to the U.S. Department of Energy, heating and cooling systems can lose more than 30% of their heated and/or air conditioned air due to leaky duct work. With a ductless mini-split system, there is no chance of this type of energy loss; each indoor head delivers heating and air conditioning to the room it’s located in without having to circulate air through a duct system. Ductless mini-split systems are up to 40% more efficient than traditional heating and cooling systems, which results in lower utility bills. In addition, ductless mini-split systems are inherently a zoned HVAC system. You can heat and/or cool the rooms you use while saving money on the rooms you don’t use.

Because ductless mini-split systems are so efficient, local utility companies offer rebates as incentives for their customers to make the switch. In Vancouver, WA, the Clark County PUD offers up to $1,000 in rebates and in Portland, OR the Energy Trust of OR offers up to $800 in rebates. Also, make sure to check to see if there are any manufacturer rebates and promos offered at the time of purchase.

  1. Environmentally Friendly

Ductless mini-split systems are an environmentally friendly heating and cooling system. They are designed to meet Energy Star standards. Also, ductless systems use a type of refrigerant called R410A. This refrigerant is known for being environmentally friendly because it does not negatively impact the ozone. If you are wanting to “green up” the heating and cooling in your home then installing a ductless mini-split is a great investment.

  1. Zoned HVAC System 

Ductless mini-splits are a zoned HVAC system, which can be designed to be set up from 1 to 8 zones. You have the freedom to chose where you want the indoor heads and “zones” to be located before the install takes place. Each indoor head comes with a thermostat and controller, which makes changing the temperature in each zone easy and increases your families comfort at home. It’s a system that is tailored made to you!

  1. Easy to Install

The installation process for ductless mini-splits is relatively easy. Without having to add duct work to your home, it decreases the length of time for the install since the installers don’t have to do any major cuts into your walls. In fact, installers on average only have to make a three inch hole into your walls for the ductless outdoor and indoor units. A quick, easy and clean install means you will have a running system quickly so you and your family can be comfortable.

  1. Improved Indoor Air Quality

Having a heating and cooling system with duct work requires cleaning and maintenance. Up to forty pounds of dirt is created in a six bedroom home annually. This dirt is circulated around your home in a ducted HVAC system five to seven times a day. With a ductless system, you don’t have to worry about duct cleanings or how your duct work is negatively impacting your health.  A ductless system does not circulate mold, viruses, etc. like dirty ducted systems do.  If you are experiencing allergies, sinus problems, and/or increased dust in your home it may be due to your existing dirty duct work. A ductless system is a great solution to this problem.

Filters need to be changed every 1 month up to 1 year depending on the filter type.

  1. Program Your Thermostat

To avoid your AC system from working harder than it needs to, program your thermostat while you are away and when you are sleeping. Energy Star recommends that you set your thermostat to be 10 degrees higher than normal when you are not home and when you are sleeping. Not only does it give your system a break, but it saves you money on your utility bills.

air duct cleaning duct cleaning services vent cleaning

Did you know that the air in your home circulates through your HVAC system 5-7 times a day? If your duct work is filled with mold, fungi, dust and/or other contaminants, then all that dirt, grime and bacteria is also circulated through your home 5-7 times a day. In fact studies have shown that indoor air can be up to 70 times more pollutant than outdoor air.

Dirt, mold and other contaminants in your HVAC system can exasperate existing health conditions of your family living in the house. Respiratory problems such as asthma attacks can be induced by contaminants in duct work such as mold, dust, etc. that you are breathing in. These same culprits can cause inflammation in your nasal passages when you breath them in leading to continually sinus problems. Lastly, dirty duct work and vents can cause allergic reactions such as sneezing when dust, pollen and other contaminants are present; this might be especially noticeable during the Spring season.

Duct Cleaning Services

A vent cleaning and air duct cleaning can help alleviate airborne illnesses as well as reduce mold growth, and remove unwanted odors from your heating and cooling system. On average, we recommend that you get your duct work cleaned every 5-7 years. However, if you meet any criteria below you should consider scheduling an air duct cleaning more often if you:

AC repair AC service local AC repair ac company in vancouver air conditioning repair service

  1. Lack of AC service and maintenance

The most important thing you can do to protect your cooling system is schedule an AC service known as an annual maintenance. Over 90% of all mechanical breakdowns are due to dirt. Dirty coils cannot transfer the same amount of heat as clean coils. With a dirty coil, your AC will run harder and longer causing unnecessary wear and tear on your system. This extra strain on your system may even result in your compressor and/or fan failing. During an annual maintenance, your trained HVAC service technician will clean the coils and perform an important safety inspection. Not only does an annual maintenance and AC service protect your system from needing an air conditioning repair service, but it also gives you peace of mind. Learn more about our Club Membership, which a free annual maintenance as well as discounts on service and repairs.

  1. Dirty filter

An easy way to protect your AC from needing local AC repair is to change your filters frequently. Your filters should be changed every 1 month to 1 year depending on the filter type. Dirty filters block the airflow of your system, which decreases efficiency and can cause higher utility bills. They can also add to dirt and buildup of other important components of your system including the evaporator coil. According to the Department of Energy, you can save between 5%-15% of your AC energy usage just by changing out a dirty filter. Avoid added strain and breakdowns of your system by keeping your filters clean so it can circulate air without blockages.

Filters can be purchased from our office location at 6109 NE Hwy 99 Vancouver, WA 98665. Our office is open Monday through Friday from 8am to 4pm.

  1. Refrigerant leak

Refrigerant is what we call the substance used to transfer heat in refrigeration process. The amount of refrigerant shouldn’t change within your system unless there is a problem.  If a leak develops in your AC’s refrigeration system, you will experience decreased efficiency and increased wear on the system. Your system’s compressor feels the most strain and may fail over time. If you are noticing that your system has trouble cooling, your utility bills are higher and/or there are hissing noises coming from your HVAC system, your AC may have a refrigerant leak and need an local AC repair.

  1. Condensation issues

Through the refrigeration process, heat is removed from the home and transferred to the outside.  In this process, condensation is formed. One quality of air conditioning is that it dehumidifies your home causing the home to feel more comfortable on the hottest days. Condensation created by your HVAC system must be drained properly.  If the condensation removal system has not been properly maintained, it can result in system damage, home damage and/or health issues if not handled quickly with an AC repair. Water can ruin your insulation, ceiling, and walls. In addition, the presence of water within your duct work can become a breeding ground for mold and bacteria, which will be circulating throughout your home via your HVAC system. During an annual maintenance, technicians clear condensation systems to ensure proper operation and reduce possibility damage caused by your system.

  1. Weak electrical components

Weak electrical components can cause the unit to work harder resulting in more serious failures and breakdowns. During an annual maintenance with your AC company in Vancouver, your service technician will evaluate and replace with your approval, any weak electrical components. Having a set of trained eyes evaluate your system before the height of hot weather is a fantastic preventive measure. You don’t want to be stuck in a heat wave needing AC repair. Local AC repair companies are busiest during these heat waves and it can be difficult to schedule an air conditioning repair service.

AC set your thermostat

  1. Use your blinds and curtains

During the day, lower your blinds and/or pull your curtains. It is best to use blinds and curtains that are lighter in color. This will limit the amount of outdoor heat that will enter your home due to sun rays. The cooler the house without AC than the less energy you will need to use to condition the air.

  1. Use a ceiling fan

Though using a fan doesn’t air condition the air, it does create a wind-chill effect, which results in you feeling around 6 or 7 degrees cooler. With the wind chill effect, you can set your thermostat higher than normal and still feel comfortable.

  1. Re-evaluate thermostat placement

Is your thermostat hung in a location that gets direct sunlight? Is your thermostat near major electronics such as a TV or a lamp? If so, consider moving your thermostat to a location that won’t get direct sunlight or heat from electronics. This way your thermostat will get a more accurate reading of the temperature in your home and will only run the AC when necessary.

  1. Program your thermostat

To save money on your utility bills, set your thermostat as high as you can while still being comfortable. When you leave your house, make sure to set your thermostat 7-8 degrees higher than you have it set when you are at home. Resist the urge to set your thermostat temperature lower than normal. This only results in higher utility bills and doesn’t lower the temperature of your home any faster.

  1. Replace your AC

If your current AC or Heat Pump is 12-15 years old, it may be time to consider replacement. New systems are more energy efficient and will most likely save you money on your utility bills. Plus, you are less likely to have to worry about breakdowns during the warm summer months and costly repairs. Check to see what rebates are available in your area.

  1. Maintain your AC

Maintaining your AC is key to saving money on your utility bills during the hot summer months. Schedule a tune up for your HVAC system once a year. The tune up will need to be done by a professional HVAC service technician. This will help to prevent breakdowns as well as addition wear and tear on your system caused by dirt. Our Club Members receive discounts on their annual maintenance as well as any other service and repair on their HVAC system.

Make sure to change your filters regularly. Typically filters need to be changed every 1-6 months or when dirt is present in the filter. Changing your filters regularly will also help keep your system working as efficiently as possibly.

Lastly, make sure your ducts are cleaned and sealed can greatly improve your system efficiency. On average, homes lose 20-40% of it’s air conditioned air through leaky ductwork. A simple duct sealing can resolve this issue keeping your air conditioned air circulating with your home.

zoned HVAC system


A zoned HVAC system allows you to set different rooms in your home to different temperatures. With a ducted system, you can zone your home by using dampers within your duct work and individual thermostats in each of the rooms and/or areas that you zone. Ductless systems are inherently zoned.  Instead of duct work distributing heating and air throughout the home, indoor heads in each room perform this function and are controlled by their own thermostat and remote. In fact, some can even be controlled from your smart phone.  Here are the top five benefits of installing a zoned HVAC system:

  1. Energy Efficient

Think of your heating and air conditioning system like you do the lights and electricity in your house. You don’t leave them on all the time do you? When you leave one room, you probably turn them off. You also probably turn them off when you leave the house. It’s more energy efficient to do so. It works the same with your HVAC system. Why would you want to heat rooms that you aren’t using? Using a zoned HVAC system allows you to save energy since you have the choice to heat the rooms you use instead of the whole house. If your home has any of these features, you will save the most money by switching to a zoned HVAC system:

  1. Saves Money

Since zoned HVAC systems are so energy efficient, they can save you up to 30% of your utility bills relating to heating and cooling. This type of savings is especially noticeable during the peak season for your utility bills. No one likes paying a mountain of utility bills just to stay comfortable in your own home.

  1. Longer System Life

When you zone your HVAC system, you end up using it less than you would otherwise. Not heating and/or cooling your entire home at the same temperature all the time extends the life of your system. Less overall use equals a longer system life on average.

  1. Comfort

Do you like having your bedroom a different temperature than your living room and/or kitchen? With a zoned system this isn’t an issue. You can decided what temperature you would like each zone in your home to be. This type of room to room personalization is the ultimate home comfort. In addition, a zoned HVAC system enables a more stable overall temperature in each of the zoned areas as well as eliminates hot and cold spots.

  1. Convenient

Zoned systems are convenient as each zones comes with it’s own thermostat and remote. No longer do you have to go down a flight of stairs to change the temperature. Now you can do so from the comfort of your own couch.


what to know before buying a new furnace

You have decided to either replace an existing furnace or add a furnace to your home. Here are a few aspects of furnaces you should know about before investing in a new furnace.

Furnace Types

Furnaces can run on different energy sources such as electric, gas and oil. Electric furnaces are environmentally friendly, and energy efficient. However, it costs more money to create heat from electricity rather than other energy sources such as gas or oil. Gas furnaces can be the most affordable while oil furnaces though effective are not environmentally friendly.

Furnaces can also be single stage, two stage or variable speed. A single stage furnace can only run at one speed, which is high. In effect, this means it’s running at a full sprint all the time no matter what the weather is outside. A two stage furnace has two settings-high and low. It will run for the most part on low, but it will kick into high gear if necessary during cold spells. Last, but not least a furnace can be variable speed. A variable speed furnace’s blower motor can modulate speeds depending on the temperature outside. This type of heating provides a more stable temperature in your home. It is also energy efficient and will save you money on your utility bills.


According to the U.S. Department of Energy, older furnaces are only between 56% to 70% efficient. However, new furnaces can be up to 98.5% efficient. Furnaces are rated by their efficiency with an AFUE rating, which stands for Annual Fuel Utilization Efficiency. The higher efficiency furnaces cost more, but will also save you money on your utility bills over time. If you are wanting a highly efficient system be on the look out for a furnace that has an Energy Star logo on the yellow Energy Guide or ask your Comfort Advisor.


Each brand offers different manufacturer warranties for their products. Furnaces can come with a parts warranty, labor warranty and heat exchanger warranty. Some contractors offer warranties on top of the manufacturer warranties. Make sure to compare inquire about what warranties are available for each furnace option.

Rebates and Incentives

Utility companies incentivize customers to upgrade their heating and cooling systems through rebates.  Clark PUD and Energy Trust of OR offer rebates and incentives. In addition, manufacturers offer rebates during their promotional periods, especially on higher efficiency equipment.  Ask your Comfort Advisor about these available rebates and incentives or click here.


The most important day in the life of your furnace is the day it’s installed. Protect your new furnace by having a licensed HVAC contractor do the installation. It may be cheaper upfront to have an unlicensed Chuck with a truck install your new furnace, but you will most likely pay for it in the longer run with repairs and efficiency issues. Miller’s Heating & Air’s is a licensed HVAC contractor and our installers are highly trained and professional.


air source heat pumps


Heat pumps are a great heating and cooling solution for homes located in moderate climates such as Vancouver, WA and Portland, OR. They are unique because they can both heat and cool a home through environmentally friendly means. In this article, we will be discussing the most common type of heat pumps, which are ducted air source heat pumps. There are also ductless air source heat pumps options as well for homes without duct work. Rebates on heat pumps are often offered from local utility companies since they are so energy efficient and environmentally friendly. See if there are any rebates in your area by clicking here.


  1. Heating and Cooling Capability

Air source heat pumps transfer heat instead of creating heat like traditional heating systems such as furnaces. The key is it’s use of refrigerant and electricity. During the winter, a heat pump uses electricity and refrigerant to move heat from outside the home inside and moves the cold air from within the home outside. The same is true in the summer, but in reverse. During the summer, a heat pump moves cold air from outside the home to inside the home and moves the hot air from within the house outside. Since a heat pump can cool as well, it’s a great replacement for an air conditioner.

  1. Energy Efficient & Environmentally Friendly

Heat pumps do not burn anything to create heat instead they transfer and move heat from outside the home. In a very real sense, heat pumps use the renewable energy of the Earth’s air to heat and cool your home along with electricity and refrigerant.  Heat pumps are environmentally friendly and do not pollute your home, community or the planet to keep your family comfortable while in doors.


  1. Lowers Utility Bills

Do you currently have a furnace or base board heat and want to save up to 50% on your electricity costs? Consider replacing it with an air source heat pump. After installing a heat pump, you would see a significant decrease in your utility bills. Does it seem to good to be true? Check out the U.S. Department of Energy’s website if you don’t trust us. We got the statistic from them.


  1. Improved Indoor Air Quality & Comfort

Heat pumps are not only more environmentally friendly and more cost effective than traditional HVAC systems, but they also improve your home’s indoor air quality and your family’s comfort. Because heat pumps don’t use combustion to heat the home there is no risk of carbon monoxide filling the air from your heat pump system. In addition, a heat pump system doesn’t dry out the air in your home like a traditional system does. Instead more moisture is kept in the air, which results in a better humidity balance and comfort in your home.
