HVAC Specialists Explain Volatile Organic Compounds

Most people spend the majority of their time indoors; it’s important to consider this when buying a swamp cooler or refrigerated air conditioner. After all, indoor comfort is not just about maintaining a desired temperature; it is also about making sure that your home has good indoor air quality.

The Meaning of HVAC Energy Efficiency Ratings

When buying new heating and air conditioning systems, you have to consider certain factors. The main thing to consider is the system’s energy efficiency ratings. Scoping out a service unit’s SEER or EER numbers can help determine if a system can satisfy your air conditioning needs. Here’s a look at the meaning behind the energy efficiency ratings of HVAC systems.

Thinking of Replacing Your HVAC System? Here’s why Fall is the best time to do it.

There comes a time when every homeowner must face the inevitable – your HVAC system needs to be replaced. Replacing your heating and cooling system is not something that you often have to deal with, so you may be wondering, where do I start? The more you prepare yourself for this event, the better off you will be when the time comes to upgrade or replace your system.

Fall is the best time to replace your home comfort system, so if you have been thinking about upgrading or you need a replacement, why not start the process now? Below we will talk a little bit more about why fall is the ideal season for HVAC replacement and what you should consider when exploring your options for a new HVAC system.

Why You Should Replace Your HVAC System in Fall

Here are just a few reasons why you should consider replacing your HVAC system in the fall:

  1. Convenience

Fall is the most convenient time to replace or upgrade your HVAC system as the weather is more moderate, so you and your family can enjoy more comfortable temperatures during the installation process. In addition, HVAC companies are experiencing less emergency calls during the fall, so they can often have a more convenient schedule for consultation and installation.

  1. Time

Since you are using your heating and cooling system less in the fall, this offers you more time to find the perfect system for you. You can do your research and consult with HVAC experts in order to find the right heating and cooling system to meet your home comfort needs. It is better to plan ahead and know what you want ahead of time, rather than rushing to find a new system once yours eventually breaks down.

  1. Price

Another reason why fall is often the best time to replace your HVAC system is that many companies offer rebates and special promotions during the fall system. Fall can be slower season for HVAC so many companies provide some incentive for homeowners by offering significant saving son new systems.

Your Top Heating & Cooling Questions Answered

As a homeowner, it’s your responsibility to maintain your home and all of its components to sustain the best value, comfort and security for your home. This is a lot to ask of someone who is likely a parent and a full-time employee. We certainly don’t expect you to know it all. This is why we take it upon ourselves to proactively answer the important questions that homeowners may have when it comes to the ins and outs of their home’s heating and cooling.

Heating and Cooling Questions

Common Heating & Cooling Questions

Below, we’ve taken the time to answer some of your top questions about heating and cooling your home:

Where is my air filter?

To check on your air or furnace filter, you’ll have to know where it is first. Most units will have the filter next to the unit on the return duct. For older units, the filter is often inside the furnace next to the blower. Other units have a central filter grille that will be located on a wall or ceiling in the house.

How often should I check my air filter?

We recommend that you check your air or furnace filter at least once a month. You will want to check more frequently during high use seasons. This timeline ensures that if the filter is compromised or dirty, that it can be cleaned or replaced before it can cause damage to the unit or worsen the air quality of your home. If you have a replaceable air filter and it is dirty, do not bother trying to clean it, you are better off replacing it, as it is more prone to wear and tear than a more sturdy pleated filter.

What is the ideal humidity level for my home?

The humidity level of a home is vitally important for both safety and comfort. A home that is not humid enough can be too dry for its occupants causing dry throats, noses and potentially damaging electrical equipment. Meanwhile, a home that is too humid is at risks of inviting pests and mold into their home. The ideal humidity level for a home falls within 35-50% with 40-45% being the most ideal.

How does air conditioning work?

The function of an air conditioner is not actually to pump cold air into the house, but rather to suck the heat out of the house and circulate cooler air from within the home until the home reaches the ideal temperature, humidity and air quality. The heat is pulled through the unit and out through the ventilation system, while the cooler air is pushed through the ductwork of the home. If you feel as though heat is not leaving your home quickly, check your ventilation system and if you don’t feel like cool air is flowing through your home fast enough, consider cleaning your ducts.

What size air conditioning unit do I need?

There are more factors than the size of home or business that goes into the size of unit that is required to heat or cool the space. Yes, size is one of the biggest components of this decision, but factors such as window size and quality, home orientation with regards to the sun and overall energy efficiency to the home. If a home is properly insulated and receives a bounty of free energy from the sun, it may be able to use a smaller unit. On the other hand, if a structure is poorly insulated and is shaded in the winter or baking in the sun in the summer, it will likely require a larger unit to properly heat and cool the building. Ultimately it is recommended to have an Albuquerque HVAC specialist come to your home to properly size your new HVAC unit.

What’s the difference between a variable speed furnace and a traditional furnace?

A traditional furnace will run at one speed, or 100%, at all times. This sounds ideal in that it should quickly heat up your home, however, not all temperature differences require this much energy to effectively heat your home. A variable speed furnace has the ability to first release an initial burst of heat at 65% percent capacity. Only if it is completely necessary will a variable speed furnace kick into 100% capacity. This not only saves energy (variable speed furnaces are more expensive but the energy savings can take as little as 4 years to pay off the difference), but the unit will be notably quieter. There is also an additional bonus to heating up a home more slowly, in that it allows the air in the home to be properly filtered and replaced to avoid the buildup of humidity or poor air quality.

Absorption Refrigeration: How It Works

When most people think of the way that refrigerators work, they picture compressors and cold air. That’s why it’s so hard for many people to understand the concept of absorption refrigeration. It’s easy to see where their questions come from and why it can be a bit tricky to wrap your mind around. After all, how can the application of heat make something cold? It’s actually simpler than you might think.

absorption refridgerator

The Setup

One of the most interesting things about this kind of unit is that there are no moving parts. At all. With no electric motors or compressors that can fail, an absorption refrigerator is incredibly reliable. When these first hit the market, it meant that customers could enjoy marvelous warranties far beyond what was possible with traditional models.

An AR unit has four basic parts. The broiler, condenser, evaporator, and absorber come together within this ingenious design. Flexibility is another benefit that they offer. An absorption refrigerator can be powered by electricity as well as kerosene or gas. Adaptability is always a benefit, particularly when it comes to appliances.

Within these refrigerators, you’ll find ammonia, water, and hydrogen. The pressure within the tubes is great enough to condense ammonia at a certain temperature. Of course, different units are designed with different thresholds.

How Heat Makes Cold

Whether it’s fueled by electricity or gas, heat is applied to the boiler system. The temperature rises and boils the ammonia rather quickly. Small bubbles of the gas rise up, bringing with them an ammonia solution. This combination then enters the siphon pump and is split into two parts to continue the process.

Any of the weak solution is rerouted back into a tube and out of the way. The less dense gas travels into the vapor pipe. It then moves along to the water separator. In this chamber, the ammonia is purified from any water. The water is condensed and returned to the boiler system. The ammonia vapor, now unmixed, makes its way into the condenser.

Once there, the circulating air brings the ammonia back to a cooler liquid form and then transports it to the evaporator. This portion is full of hydrogen. It slides across the ammonia, reducing the pressure enough that it can once again evaporate. As it’s transformed back into a gas, it takes heat from the compartment and drops the temperature.

Ammonia and hydrogen are then moved to the absorber. The tube of weak solution, mentioned earlier, flows through this area and drags the ammonia away. The hydrogen rises back to the absorber coil, and the strong ammonia returns to its starting point at the boiler system.

Stop Mold Growth in Your Business HVAC System

Due to condensation, HVAC systems can be prime locations for mold growth, and these systems can distribute mold throughout the building. Visible mold always signals a potential problem in terms of health-related complications and damage to building structures. Stopping mold growth is imperative for sustaining good indoor air quality (IAQ).

HVAC Maintenance for Mold Prevention

It’s important to schedule regular cleaning and maintenance of your HVAC system. Make sure your contractor or technician checks the following for a thorough inspection.

Coils and Drain Pans

Air is dehumidified through cooling coils, and the condensate water drips into the drain pan before exiting through a deep seal trap. When the drain pan isn’t properly designed and maintained, standing water can accumulate, which creates a microbial habitat. In addition to proper sloping, cleaning the drain pan regularly is an important component of healthy IAQ.

Humidification and Dehumidification Equipment

Wet surfaces should be drained and periodically treated in order to prevent microbial growth. Your technician should also prevent duct linings from becoming moist from sprayed water.

Outdoor Air Dampers

Screens and grilles can become obstructed from mold growth that has developed from dust and debris. The technician should clean these surfaces regularly in order to remove dust build-up.

Air Filters

The air filters should be replaced regularly, either on a scheduled basis or because of the air filter’s pressure drop. Fans should also be shut off when changing the filter, in order to prevent air contamination. Your technician may recommend getting a higher-efficiency filter in order to improve your indoor air quality. Purchasing a compatible high-efficiency filter can also minimize energy use.


While it’s normal to have some dust on duct surfaces, it’s important not to have dust on areas with restricted airflow, areas subject to condensation or moisture, and duct lining, as these locations are susceptible to contamination. The technician should fix any overly wet areas, such as the internal lining which can become chronically damp.

Return-Air Plenum

The space over the ceiling tiles is often used as a return-air plenum. Materials and supplies shouldn’t be in the plenum, as the area can become contaminated and disrupt airflow. All exhaust systems that pass through the plenum should be properly maintained in order to prevent leaks, as well as to prevent exhaust from entering the plenum. The technician should also check for condensation in the plenum areas and on pipes.

Cooling Towers

The chemical treatment and water quality should be periodically monitored to prevent microbial growth. It might also be necessary to physically clean the cooling towers in order to prevent the accumulation of sediment, and to install drift eliminators.

Air Intakes

The HVAC technician should check the areas where the outdoor air enters your HVAC system. He or she should also inspect any organic material that has accumulated in or near the HVAC intakes. Airborne fungal spores can become elevated when the intakes are near dumpsters, boxes, garbage cans, standing rainwater, paper, lagoons, ponds, and earth and vegetation that has been freshly disturbed.

Contact Anderson Air Corps for a thorough investigation of mold growth and to prevent mold from accumulating in the future. Doing so can protect your business as well as its occupants, and regular maintenance is the best way to keep mold at bay.

What Size Air Conditioner Do I need for My Home?

Getting a new air conditioning is a big expense and a big choice. How do you know which unit is right for your home? To make sure your indoor space is comfortable, that it is cooled efficiently, and that you won’t be paying too much on your energy bills, picking the right size for your new AC unit is a good place to start.

Factors to Help You Choose the Right Size AC 

The size of AC unit you choose is important. Go too small and it will run constantly without ever cooling your home adequately. With a unit that is too large it will cycle off rapidly and never really cool the structure of your home. Here are some important factors to consider for picking the right size:

How big is your home?

An obvious consideration is the size of your home. AC units are sized by TON rating, or cooling capacity. The larger your home, the higher the rating you need. It is important to consider volume of space too, not just square footage.

What about windows and insulation?

It’s also important to think about how your home holds on to heat. If you have good insulation and newer windows, you can make do with a smaller AC. With poor insulation or older windows, a larger unit may be needed to keep your home cool.

Do you get a lot of sunlight? 

Where those windows are in the home and how much heat they let in is also important. If you have a lot of south-facing windows or a lack of shade around windows, you may need a larger AC unit to cool your space adequately.

Making the Most of Efficiency

Efficiency is another important factor to consider when choosing what size air conditioner you need for your home. It is important in making your home as comfortable as possible without paying too much each month. If you have factors that make your home more difficult to cool, you might want to address those before getting a new AC: get better insulation, change out your windows, or plant shade trees.

You can also look for a unit that is the right size for your home, but that has a high SEER rating. This is the rating that tells you about efficiency. The higher the rating, the more energy efficient the unit is. A high SEER unit may cost more, but it could save you money in the end. If you’re stuck and unsure what unit is right for you, let one of our experts help. And keep checking back in with our Anderson Air Corp blog for the latest HVAC information and more helpful tips.

Commercial Heat Pump Troubleshooting Tips

A heat pump style of HVAC system is an efficient way to heat and cool a space. Instead of generating heat or cooling air, it pumps heat either inside or out to warm or cool the inside of a building. While a heat pump may be more efficient than a traditional system, it may also develop more problems. Before you panic thinking your whole system is shot, consider these three common problems and what they mean.

Your Heat Pump is Running Constantly 

This is not uncommon during the hottest months of the year. Your heat pump is struggling to get the temperature down to where you have set it while outdoor temperatures are soaring. Check your thermostat to make sure the temperature has not been set too low. Call for service if you raise the temperature setting, but it’s still running.

Your heat pump may also run constantly during very cold weather and this is not always a problem.  Heat pumps run more than a furnace. However, if the outdoor temperatures are above 30 degrees you could have a problem: a frozen outdoor unit, leaking coolant, a broken compressor, or a system that is too small for your space.

Heavy Ice on the Outdoor Unit 

It is normal for the outdoor component of your heat pump system to frost over in the winter, but ice is can signify a problem. It can also cause problems, namely your pump not being able to warm your space. Normally the outdoor unit should periodically defrost itself. If it has built up a layer of ice, this function could be broken. The unit may also be low on refrigerant or there could be water leaking into the unit from your eaves or gutters. Another cause of icing is snow piling up around it. To avoid this, clear the snow out regularly.

Cold When You Should Have Heat 

If your indoor space isn’t heating there could be a simple solution. First check to see that the heat pump has not been accidentally switched to AC mode. Also check he outdoor unit to see if it is covered in ice. If these are not issues, it could be that your system has gotten dirty or has gone too long without regular maintenance. This can lead to long-term damage, so call for service and a cleaning soon.

Often an issue with your heat pump system is minor. A few troubleshooting tips may be all you need to figure out what is going on and what is needed to fix it. On the other hand if you have repeated issues, it may be time for a replacement.

The Benefits of Controlling Indoor Air Quality

Monitoring and controlling your indoor air quality (IAQ) offers a number of benefits. In addition to safe-guarding the health of a building’s residents, controlling IAQ can improve productivity and even help your HVAC system to work at maximum efficiency. These days, people spend an estimated 90 percent of their time indoors and breathing indoor air. As a result, it’s hardly surprising that unhealthy indoor air can have a serious impact on other aspects of our lives.

Poor IAQ Has Negative Effects on Health

Exposure to poor air quality can have a negative effect on health almost immediately. Symptoms and problems that can arise shortly after exposure include headaches, upper respiratory congestion, fatigue, dizziness, and irritation of the eyes, ears, nose and throat. Many people experience these discomforts on a regular basis without realizing that poor IAQ may be to blame.

Potential health problems increase with long term exposure to indoor air pollutants. Poor IAQ can be a contributing factor in a number of debilitating or even fatal illnesses, including heart disease, respiratory disease and cancer.

Sick Building Syndrome Lowers Productivity

When many people who regularly occupy a building suffer negative health effects from poor air quality, the phenomenon is known as Sick Building Syndrome (SBS). SBS usually features acute symptoms that ease significantly when the affected parties leave the building. SBS tends to occur in office buildings with open-plan offices, in which many people are exposed to the same air quality conditions.

Sick Building Syndrome can arise from a number of different factors, and often a combination of several factors. Airborne or chemical pollutants, temperature and humidity problems, poor ventilation, ozone emissions from office equipment, and high concentrations of total volatile organic compounds (TVOCs) can all contribute to unhealthy indoor air.

Offices that suffer from SBS can suffer major reductions in productivity, These buildings will experience a very high number of employee sick days, and the performance of employees who are present is also likely to be impaired.

The Green Building Problem

Surprisingly, “green” buildings are among the most likely to suffer from Sick Building Syndrome. These offices, built to have a minimal impact on the outdoor environment, too often fail to consider their indoor environment. Green buildings frequently limit the amount of air that circulates from the outside, and this can allow pollutants to build up indoors.

IAQ Gives Insight Into HVAC Performance

Monitoring indoor air quality not only provides warning of harmful contaminants but can also let you know how well your HVAC system is functioning. IAQ monitors carbon dioxide levels, which in turn lets you know how well your system is ventilating. Over-ventilation reduces the energy efficiency of your HVAC system, and monitoring of carbon dioxide levels is a great way to make sure your building reaches a perfect balance between air quality and HVAC efficiency.
