Getting a Heating Upgrade for Your Mesquite Home? Consider a Home Energy Audit First

Monday, April 16th, 2012

Considering an upgrade to your Mesquite home’s heating system? It’s usually a sound investment that generates savings both in heating costs and repair bills, plus it keeps your family happy and comfortable.

Before you take the plunge on new equipment, though, you may want to get a home energy audit. What you find may help you choose the right system.

A home energy audit is essentially an inspection by a professional of the materials used to insulate your home. This includes not just the insulation in the walls, but also the walls themselves, along with windows, doors and so on. The idea is to figure out how much heat is escaping your home to the outside, so an audit may also include looking at ducts, vents or anywhere else where air could flow through.

So what does an energy audit have to do with a new heating installation?

Think about it like this. There are two ways to make your home warmer: increase heat gain (e.g., get a more efficient heating system) or decrease heat loss. If you are able to do the latter, you may find that the former is unnecessary.

For example, you may get an energy audit and discover that by installing new windows and resealing your doors, you can increase heating efficiency by 10%. This could have big implications for your decision to get a new heating system, as you may decide that you can save money by getting a smaller capacity furnace. Getting the right size furnace is very important; one that is too small will not be able to heat your home to the desired temperature and one that is too large will short-cycle, which leads to uneven heating and wears down your system quickly.

A home energy audit is the first step to getting a new heating system, and one that is sure to save you money. Give A#1 Air a call to set up an energy audit today!

What Size Heat Pump is Right for My Home? A Question from Duncanville

Thursday, November 17th, 2011

One of the most important questions to answer when purchasing and installing any new heating or cooling system, no matter what type, is what size is best for your Duncanville home. You need something that has enough capacity to heat or cool your whole home comfortably; otherwise your house will consistently be at an undesirable temperature.

Some people might think that the quickest solution to this problem is to just buy a system that they are sure has a capacity larger than the size of their home. You may even be tempted to get the biggest model out there, under the logic that the biggest is the best and it will be sure to be able to cover your whole house.

While this line of thinking might make sense to you, it’s actually not a good idea. The problem with this “solution” is that you can wind up with a heat pump that is considerably too large for your needs, which means your home will consistently be either too cool or too hot, and your energy bills will be unnecessarily high.

The best way to choose a new heat pump is to have a professional do a load calculation in your home. This can be a highly technical process, so it is best to leave it to the pros. However, here are some quick tips and other things to consider on the subject:

  • There are a lot of variable to consider in doing a calculation like this. A contractor doing a load calculation will consider the type of construction, what kind of insulation you have installed, what kind of windows you have, whether there is an attic, how many people live there and many more factors.
  • Also, since heat pumps are used for both heating and cooling, different contractors may opt to do the calculation in different ways. Some will estimate capacity based on heating, while others will base it on cooling. Ask to see which is the case for any estimate you receive.
  • If you are getting a new heat pump as a replacement for an existing one, or even a different heating/cooling system, check the capacity of the unit you are replacing. That can be a good place to start. You will at least be in the right ballpark.

All of this means doing some extra leg work up front, but getting the proper sized heat pump is well worth the effort.

How to Calibrate Your Thermostat: A Tip from Denton

Sunday, November 6th, 2011

Have you ever set the thermostat in your Denton home to a desired temperature and “hoped for the best?” Maybe it’s because the temperature setting you expected this finely tuned instrument to maintain just isn’t right. You may see 70 degrees on the thermostat but the home feels more like 65 degrees. In fact, if you used a hand-held thermostat, you might get real proof that your thermostat is not working like it should.

There are reasons for a malfunctioning thermostat and solutions to correct them, namely calibration. First, let’s look at some reasons why a thermostat can be out of kilter.

The first thing to note is that thermostats are very sensitive instruments and change to the slightest changes in temperature. An incorrectly installed thermostat or one that is accidentally bumped or jarred can malfunction. It may wind up out of level, causing it to operate incorrectly. Possibly the most common problem affecting accuracy is a build-up of dirt, which can affect the calibration of the thermostat. Other problems may be caused by loose wiring.

Here are some steps you can take to check your thermostat for accuracy and recommended actions.

  1. Use a standard glass thermometer to check the room temperature. You should mount it on the wall nearby your thermostat and use some padding to keep it from actually coming in contact with the wall, which could affect the readings.
  2. Wait 15-30 minutes for the thermometer to adjust to the temperature and enable it to give the most accurate reading. Once the time has elapsed, compare its temperature reading to that on your thermostat.
  3. If there is more than a one degree variation, your thermostat may be dirty. Remove its faceplate and examine it. If there is dirt or dust inside, blow it out. If you can reach the contact points, you can clean them with a new dollar bill (and speaking of dollars, a clean and accurate thermostat will make your furnace run more efficiently and save you money on your utility bill).
  4. Some thermostats use a mercury vial which can indicate if the thermostat is level or not. If it is not level, a simple adjustment using a screwdriver may do the trick. In the worst case, you may have to remove the thermostat and drill a new hole to reinstall the mounting screw in a different location.
  5. Now that you have made these corrections, check both thermostats to see if the temperatures match. If they don’t, try steps 3 and 4 again. If that still doesn’t work, your problem may be more than just a dirty, lopsided thermostat. You may need to replace the thermostat – or even look at the heating system in its entirety. It could be time to call a professional heating contractor to check out your entire system.

Today’s thermostats have few working components but are very sensitive, advanced instruments. It takes little to throw off a thermostat but luckily, it takes little effort to correct the resulting problems.

Surprising Sources of Indoor Air Pollution: A Guide from Addison

Sunday, October 30th, 2011

Indoor air pollution is a major problem for millions of homeowners throughout the country each year, including those in Addison. In fact, the EPA estimates upwards of 20 million households may have problems caused by mold, radon, humidity, exhaust or any number of other pollutant problems. However, not all of the indoor air pollutants out there are so obvious. Some are things you probably have in your home right now and don’t realize it. Here are some of the more surprising sources of indoor air pollution and what you can do about them:

  • Incense – Incense releases both carbon monoxide and benzene, two chemicals that are potentially harmful to human health. Cancer, skin irritation and asthma risks are all increased in people who spend a lot of time around incense.
  • Laser printers – Laser printers that use toner can release a number of harmful chemicals into the air. That toner is very fine and releases particles into the air that are equal to or in some cases worse than second hand cigarette smoke. If you have a laser printer, consider putting it in a well-ventilated, infrequently used space.
  • Kitchen Stove – If you have a gas stove, it releases Nitrogen Dioxide when on, an unsafe gas that is odorless and fills your home quickly. This gas is bad for respiration and can cause asthma attacks. To solve this problem, simply make sure you stove is ventilated properly when cooking.
  • Spackle – Old spackle – the kind used before the 1980s often contained asbestos which can still be there, waiting to be disturbed. Old asbestos, while not inherently dangerous, will become so if you start doing work in your home or if the spackle starts to wear away. To solve this problem either call an abatement firm or cover the offending wall with a new layer.
  • Drapes – Those drapes are filled with contaminants that cling there, especially if humidity is a problem in your home. Dust mites in particular are bad for your health and can cause asthma and other allergies. Blinds are better than drapes for this reason.

Your home is filled with potentially dangerous problems, but you can avoid them simply by taking care to ventilate, clear away unsafe products and keep things like drapes clean (or remove them). If you’re still concerned about your air quality, call an expert to investigate.

Make Your Heating and Cooling System More Effective (and Happy Halloween Weekend!)

Saturday, October 29th, 2011

Happy Halloween weekend from everyone at A#1 Air! We hope you have a fantastically spooky time! And since a high heating or air conditioning bill can spoil anyone’s fun, here are some ways to make your HVAC system more effective.

Learning how to make your heating and cooling system more effective does not require a physics degree or an extensive knowledge of the refrigeration cycle. In most cases, it just takes common sense – and a little creativity.

For example, did you know that how your home is insulated can have a direct impact on how well your heating and cooling equipment functions? It sure can. If your walls, crawl spaces, or attic is poorly insulated or not insulated at all, your furnace and air conditioner will have to work harder to keep up – and keep you warm or cool. In some cases, your heating and cooling equipment might never be able to give you the desired temperature on your thermostat setting because the equipment has to work too hard to make up for lost heat or cooling due to poor insulation.

So what should you do? Find out if your home is properly insulated by having a load calculation or energy audit on your home. Any licensed and qualified heating and cooling contractor will be able to perform one of these tasks for you and show you where you might be losing too much of your indoor air to poor insulation. This same test can also detect any leakage through cracks in the foundation or joints or connections in ductwork. Windows and skylights are also an area of heat loss or gain. Installing awnings or trees can cut down on this loss or gain, too.

Another way to assist your heating and cooling system is to help with its air flow. In some homes, floor vents are built near outside walls or windows. Warm or cool air is vented up along the walls and windows and never flows evenly in the room. The solution is to buy inexpensive plastic air diverters which attach to the vents using magnets on the diverter. You can adjust the diverter to changing the air flow to the places that need it most – occupied spaces.

Of course, the most effective heating and cooling system is one that is serviced and properly maintained on a regular basis. If you have any questions on system maintenance, call your local qualified professional heating and cooling contractor and schedule a tune-up today.

How a Thermostat Works: A Guide from Lantana

Thursday, October 20th, 2011

Your thermostat is designed to closely monitor and maintain the temperature in your Lantana home. When you flip the switch, you want your furnace or air conditioner to respond immediately. So, it’s a good idea to learn how it works so that if there is a problem, not only will you know better what needs to be fixed – you can decide whether to call a professional in for help.

Thermostats shouldn’t need input from you other than to set the initial temperature. From there, they are automatic switches. A thermometer inside the thermostat measures the indoor air temperature. When it gets above or below the limit you’ve specified, it triggers the thermostat to send a message to your home comfort system and keep things nice and comfortable.

Types of Thermostat

Thermostats come in two forms –electromechanical and electronic. An electromechanical thermostat is the simplest and has been used for decades to regulate temperature in homes. It has a simple strip or coil of metal that expands as the temperature rises and contract as it lowers. A mercury thermometer is placed on top of the strip. The coil’s movements cause the vial to tip as the temperature changes. There is a pair of electrical contacts on either end of the vial. The mercury can absorb that electrical current when the electrical contacts touch the thermometer. The mercury then acts as a switch to turn on your comfort system.

An electronic thermostat simply has an electronic sensor that measures the indoor air temperature. You set a temperature for your room and when it changes significantly, the switch inside your electronic thermostat is triggered, causing it to turn on your comfort system.

Ways to Upgrade Your Thermostat

Most homes only need the bare minimum in their thermostats. However, there is some very exciting technology on the market these days that can add quite a bit of value to your system. Not only can you install a programmable thermostat, you can opt for zone control systems that allow multiple thermostats in different rooms of your home.

Programming allows you to set temperatures for certain times of the day. This is especially great if you are gone from the house for long periods of time each day. Why heat or cool a home when it is empty? And if you have multiple people with different temperature needs, zone control temperature control allows you to set specific temperatures for specific rooms in your home – a very enticing option for large families or multi-story homes.

What is a Matched HVAC System? A Question From Corinth

Sunday, September 18th, 2011

It has been about 200 years since the arrival of interchangeable parts during the Industrial Revolution. Today in Corinth, we laud being able to take a malfunctioning part from a car, computer or vacuum cleaner, replace it with a newly minted part from any number of manufacturers, then keep right on plugging along.

Although this is a blessing in most arenas, when it comes to an HVAC system, it is not necessarily a good practice. Heating and cooling systems work best when they are matched – but what does that mean? And why does it matter?

Why Matched Parts Matter in HVAC Systems

When referring to HVAC systems, a matched system is one in which various components are designed to work together. For example, an air conditioner and furnace made by the same manufacturer can be matched, as can a furnace and a heat pump.

Typically, the matching is done in such a way that the “outdoor” components, such as air conditioners and heat pumps are designed to work best with their “indoor” partners, like air handlers and furnaces. There are also matched systems in which every component is matched to every other.

Efficiency Boosts

While this may seem to make maintenance and repairs a pain, the practice provides a big boost to the efficiency of the system. Because the components were designed and manufactured by the same team to work in harmony, the system performs optimally. Although you can often replace one component of a matched system with one from another manufacturer and have it work fine, the system can lose efficiency, often to a significant and noticeable extent.

For these reasons, it is best to make use of matched systems in your home whenever possible. This means choosing a new matched system to install, replacing broken parts with ones that match the rest of the system and even replacing older systems with newer ones to properly match, when necessary.

It may seem like a hassle at first, but it saves money in the long run by adding increased efficiency over unmatched systems.

Allergens Affected by Indoor Air Quality Systems: A Tip From Frisco

Saturday, September 17th, 2011

Indoor air quality devices are designed to capture and remove certain allergens from the air, but what exactly is being removed and how would those allergens affect your Frisco home’s air if left to circulate? Here is a quick rundown of common allergens found inside the average home and why you should have them removed:

  • Dust Mites – Dust mites develop in high humidity conditions – above 50%. This means that the dehumidification that your air conditioner provides can help lower that to a healthy range between 35-50% which will keep them from developing and ensure your indoor air stays comfortable and safe. Dust mites are not dangerous but they can severely increase complications from asthma and other uncomfortable conditions.
  • Animal Dander – Dander from cats, dogs, birds and other furry or feathered creatures is a common allergen for millions of people. If you suspect dander as an allergy, go on vacation to a place without dander and see how it affects you or your loved ones.
  • Dust and Dirt – Dust is in every home and while it is a common irritant, it can inflame asthma or worsen allergies many times over.
  • Pollen – Pollen is a problem for anyone with seasonal allergies or hay fever. While medicine can help, proper sealing of your house and indoor air filtration can reduce the presence of pollen from clothing and animals.
  • Mold Spores – Mold develops in high humidity and in ductwork where it is dark and sometimes damp. Proper filtration with a HEPA system and dehumidification will reduce this risk.
  • Bacteria and Viruses – Bacteria can develop in the air from common colds, old food or outside contaminants. Use a UV light to remove these from your air handler or ductwork.
  • Smoke and Exhaust – Indoor/outdoor ventilation can allow in smoke and exhaust that irritates most lungs. To avoid this problem install an electronic air cleaner that can target particles in smoke.

Getting rid of allergens in the air is an important aspect of maintaining a clean and healthy household. Proper air cleaning, filtration and UV purification will reduce these allergens many times over. There are also some great tips on the Asthma and Allergy Foundation website for how to reduce the presence of those allergens to start with.

Save Money in the Long Haul with AC Maintenance in Duncanville

Tuesday, September 6th, 2011

Every year, it’s recommended that you have an HVAC contractor visit your Duncanville home and tune up your air conditioner. This visit will ensure the system is ready for the intense, regular use it will receive during the hottest months of the year. How much money can this visit save you, though? Let’s take a closer look.

Cost of Operating Your Air Conditioning

An air conditioning system on average costs a homeowner between $500 and $1500 per year to operate depending on the length of the cooling season and the efficiency of that air conditioner. That number represents top efficiency for the unit, however. When a system has dirty filters, hasn’t been cleaned properly or the thermostat is no longer calibrated accurately, the cost increases – sometimes dramatically.

Just how much more could you be spending on cooling each month when this happens? The EPA’s Energy Star website estimates an increase in cost of between 10-30% resulting from poorly maintained systems, and it can be even higher if your system is old and is severely affected by a drop in energy efficiency.

Annual Tune Up Necessities

So, what should be at the top of your tune up list? If you call a contractor, they will perform a variety of tasks including:

  • Inspect Coolant and Pressure Systems
  • Calibrate the Thermostat
  • Tighten Wiring, Capacitors, Relays and Contacts
  • Clean the Evaporator Coil
  • Clear and Clean the Condenser and Condensate Drain
  • Inspect the Condenser Fan and Motor
  • Check Compressor Efficiency

This is just a starter list for standard tune up of a central air conditioning unit. You can supplement this tune up by checking your filters once every 30 days and clearing away debris from around any outdoor units. You should also check your thermostat monthly to ensure it is working properly. If not, call for an inspection to avoid heavy increases in operating costs.

Major repairs to your air conditioning system generally take less than a day and when you’re on an annual maintenance plan, they cost significantly less than if you needed someone to fix the device in an emergency situation.

Your HVAC System and Ventilation: Some Pointers From Roanoke

Thursday, August 25th, 2011

The vent system in your Roanoke home is vital to the operation of your HVAC system. Without successful ventilation, your home won’t have the necessary clean air to keep you and your family healthy. So, what does proper ventilation require and how can you ensure your home has it? Here are some quick tips.

Install the Right Parts from the Start

Proper ventilation should result in even air pressure in your home to avoid problems with gas pilot lights. It should also be as energy efficient as possible and provide clean air through proper filtration and cleaning of the air that comes in. The best way to ensure your home has the ventilation needed to stay comfortable and safe for your entire family is to check the total size of the home and then measure the concentrations of certain pollutants like dander, pollen and smoke. A contractor can provide these services for you.

Energy Loss

Another major ventilation issue to keep in mind is energy loss. Ventilation tends to remove heated or cooled air from your home, forcing your furnace or air conditioner to work harder to replace it. As a result, you pay more for energy and it’s never quite comfortable inside.

Supplements to Ventilation

Proper ventilation should not only provide fresh air, but it should also ensure your home has clean air. The air outside may be fresher, but it can be filled with pollutants like pollen, dander and smoke. These should be removed before they get inside and into the lungs of your loved ones. To do this, you need a full sized air cleaning system that removes particles from the air down to 0.3 microns.

HEPA filters can do this, as will electronic air cleaners which can ionize and remove smoke and gas particles. Make sure you discuss filtration and cleaning with your contractor when they visit your home.
