How Important Is It To Get The Right Size Of Heating And Cooling Equipment?

When it comes to purchasing heating and cooling equipment for your home, you need to realize that size really does matter. Installing equipment with a capacity that matches the home’s size will decrease energy usage while improving comfort for you and your family.

Home builders these days are constructing more energy efficient homes. The installation of double-pane windows, weather-stripping, insulation and caulking reduce heat gain during the summer and heat loss during the winter. This allows homeowners to purchase and install smaller systems than they needed in the past without sacrificing comfort.

Anyone who thinks bigger is better when purchasing a heating and cooling system should think again. Purchasing something that is too big for the space is the most common HVAC sizing mistake consumers make. An oversize HVAC system will produce large temperature swings making it difficult to maintain comfort. It will not run long enough to remove all the moisture from the air, which makes it feel clammy. In addition to being uncomfortable, high humidity can promote mold growth, which is a health hazard.

Residential Load Calculation is the Manual J method of HVAC sizing created and recommended by the Air Conditioning Contractors of America, or ACCA. Residential Duct Design is the Manual D method of HVAC sizing used when the system includes ducts.

Both manuals take into account a variety of factors that affect a home’s requirement for heating and cooling. These factors include the number of occupants, climate, house size, house shape, roof surface color, which way the house is oriented, air infiltration rates, the types of home appliances and lights giving off heat and ceiling, window and floor area.

An experienced estimator will calculate room volumes, estimate air leakage and check the R-value of the insulation. The process should include inspecting the condition of seals and insulation as well as duct distribution in a forced air system. The contractor should provide a written estimate for sizing the system, a contract and a written warranty on labor and equipment.

Purchasing the right size HVAC system is the best way to ensure your home is energy efficient and comfortable year round.

Fans Or A/C – Which Is Better?

Fans may not be the most advanced piece of technology but they continue to be in use in our modern world. In fact, it is probably due to their simplicity that they still enjoy such immense popularity. They consist of a plastic or metal blade, a motor, a protective casing, and a few button controls. As long as electricity is applied to the motor, the attached blade will spin rapidly. This movement causes the air around the device flow quickly from the back to the front, thus increasing circulation. The blast of wind does not lower room temperature but it does promote evaporative cooling as sweat dries from skin.

Air conditioners, on the other hand, are more complicated machines that seem to keep on rising in sophistication. They are composed of a compressor, a condenser, condensing coils, evaporative coils, refrigerant, a thermostat, a control panel, air filters, tubing, and many other parts. Sometimes they come as a singular unit and at other times they are separated into interior and exterior units. They use heat transfer primarily through the refrigerant’s movement across the system to lower the temperature in a room or even an entire building. The air truly feels cold wherever you go in the confined space.

Although A/Cs offer superior comfort, their energy consumption leaves much to be desired. Assuming moderate use in a residential setting, people are likely to spend thousands of dollars per year in utility bills just to keep them running. This can be quite a burden for many who have other priorities to attend to. Fans, despite their limited cooling capabilities, consume a comparatively miniscule amount of energy. In fact, their contribution to the annual utility bills may not even reach a hundred dollars with extensive usage patterns.

In regions where heat never reaches an oppressive level, fans may well be enough to get people through the summer. However, there is a point at which no amount of air circulation will do. Having an air conditioner is still the best bet in most cases. Homeowners can have fans or A/C or both to get the comfort and the savings at the same time. The cooling effect of fans makes it possible to set the A/C temperature higher so that they consume less energy.

Should I Replace Or Repair My Equipment?

It can be difficult to decide whether it is best for you to repair or replace your equipment. There are many factors you have to consider before you make your decision. Below is a guide that will help you decide whether it is best to repair or replace your equipment:

The Age

The age of your equipment is one of the things you will need to think about when you are asking yourself, “Should I replace or repair my equipment? If your unit was built prior to 1992, replacement is most likely the better option. While replacing the unit is more expensive than having it repaired, you can actually save money by getting it replaced.

Newer air conditioners and furnaces are more energy-efficient than the ones in the past. In fact, you may be able to save 20 percent on your electric bill if you get a new unit.

The Cost

The cost is something else you will need to consider when you are deciding whether it is best to repair or replace the unit. Experts recommend that you have your equipment replaced if it is older than three-fourths of its life expectancy, and the cost of repairing it is more than one-third of the cost of replacing it.

For example, the average air conditioner lasts 10 to 15 years. If your air conditioner is over 10 years old, and it will cost $1,000 to repair, you may want to have it replaced. Replacing your unit can not only help you save money, but it can also help keep you more comfortable in your home.

Deciding whether you should have your equipment repaired or replaced can be a difficult decision because each option has its pros and cons. The cost and the age of your equipment are two of the main factors you should consider when you are deciding whether to have your equipment repaired or replaced. It is also a good idea to have a qualified technician take a look at your equipment. Every situation is different, so it makes sense to call a professional. Call us for your home HVAC needs.

Carbon Monoxide Poisoning: What Is Carbon Monoxide Poisoning and How Can You Prevent It?

What Is Carbon Monoxide Poisoning? Carbon monoxide is an odorless, colorless gas that, when ingested in certain quantities, can result in illness and/or death. It’s extremely toxic and doubly dangerous because of its near-invisible nature, and is made from car and diesel engine exhaust, cooking fumes, charcoal, wood, and other combustible materials. When burned in enclosed spaces, the CO2 can build to toxic and even fatal levels. There are an average of 400 deaths from carbon monoxide poisoning each year.

Some symptoms of CO2 poisoning are headaches, dizziness, nausea, vomiting, disorientation, and in high concentrations of the gas, unconsciousness. Many people can be suffering from the effects of the gas without knowing it until it’s too late. While anyone can be at risk for CO2 poisoning, those with upper respiratory problems, asthma, and heart disease are particularly susceptible. Infants and young children as well as seniors over 65 are much more vulnerable.
How can You Prevent It?
You can guard against toxic CO2 contamination with methods such as:1. Venting – make sure your ventilation system is clean and free of obstruction, so that gas doesn’t build in the home while you are cooking. Be sure to check your fireplace, ducts, chimneys, and pipes.
2. Have your heating/AC and water system inspected and checked annually.

3. Install a carbon monoxide detection alarm system in your home

4. Don’t burn coal, wood , or gas in any enclosed spaces without proper ventilation.

5. Do not use your oven or gas range/stovetop for indoor heating. This can also result in the very quick buildup of carbon monoxide gases, particularly in a camper or RV.

5. Never run the engine on any vehicle in an enclosed space, such as a garage with the door shut. Always open the door and allow air to circulate within the space and diffuse the CO2 effects. 6. Have a mechanic check your car exhaust system regularly. One tiny leak in your cooling or exhaust systems could result in toxic gas buildup in the cab of the vehicle.

Complying With Efficiency Standards Requires A Substantial Investment

Each year the U.S Department of Energy, also called the DOE, works with professionals in the HVAC industry to reduce the amount of energy and fuel wasted during the operation of HVAC equipment. This endeavor is one that benefits the environment, and homeowners benefit with deep savings on energy costs. The DOE has created HVAC Efficiency Standards to ensure that manufacturers of HVAC equipment comply by creating more energy efficient equipment.

An AFUE rating is the rating that determines how efficient a furnace is. Condensing furnaces are the only furnaces with an AFUE rating of 90. These furnaces are considered to be extremely efficient because this rating means a furnace only wastes 10 percent of the fuel required to operate it. The DOE has segmented northern states and has created a rule that enforces homeowners in states like New York to heat their homes with furnaces that have an AFUE rating of 90. This rule overrides the current minimum AFUE rating of 78 for combustion furnaces and was supposed to be enforced in the year 2013.

Though most homeowners jump on the opportunity to save money and to preserve the environment and natural resources, complying with this new HVAC Efficiency rating is a financial burden for homeowners. Many homes currently have combustion furnaces and the switch to a condensing furnace with an AFUE rating of 90 means making major modifications. A condensing furnace requires a different type of vent system, and many homes lack the appropriate architectural design and space to accommodate this new system. Making the necessary modifications means homeowners have to invest far more than just purchasing new equipment.

For some homeowners this money is just not in the budget, which will make it hard for them to comply with new efficiency standards. Due to the financial burden that many homeowners are unprepared to take on, experts in the HVAC industry have the new efficiency standard currently held up in court until a feasible plan can be established. Since the enforcement of this new rating is inevitable, many homeowners have decided to have their homes compliant before the rating is enforced. To discover the latest news on the raising of efficiency standards or to learn more about efficiency compliant furnaces contact a local HVAC contractor today.

Is Your HVAC System Protected From Power Surges?

A power surge is a brief spike in electricity voltage passing through the line. Household electronics may survive one power surge; however, hard-wired electronics are the first to suffer when a power surge occurs. Heat pumps, furnaces, boilers, and air conditioning units represent a major investment; therefore, just because they may withstand one power surge does not mean they can handle multiple others. All electrical appliances are designed to handle a specific voltage. Homeowners should therefore take reasonable steps to protect their HVAC systems from power surges.

 

Many different things can cause a power surge, and no home is immune to power surges. Some of the most common causes of power surges include:

• Electrical or lighting storms

• Faulty wiring

• Power outages

• Downed electric power lines

• Power plant maintenance operations

• Faulty electrical components

 

Power surges are random, and there is no way that one can evade or predict them. However, homeowners can take a few simple steps to protect their comfort systems from expensive damage. One is by securing the whole house at the point at which power is connected. Secondly, one can use a surge protector directly connected to the household appliance in use. Surge protectors work by grounding the additional voltage, thereby protecting the sensitive electronic devices. An HVAC surge protector will shut off the system to protect its electrical components.

 

Shutting the system down is what saves it from succumbing to the damaging effects of a power surge. Once the system shuts down, it is important to follow the right steps to restart it properly. Each heating and cooling system varies in terms of the booting procedure after a forced shut down. Some systems are easy to handle, but some might need someone with a bit of technological knowledge. The best way to handle a system reboot is to call an experienced and certified service technician for high quality HVAC maintenance.

 

In summary,as a homeowner you should understand that all homes are subject to spikes and surges; therefore, if you want to protect your home utilities, you need to invest in a good home power surge protection system. Your heating and cooling system is an investment worth protecting.

NATE Certification Provides An Additional Level Of Expertise

It’s not unusual for people to ask — what does NATE certified mean? After all, unless you are in the heating and cooling industry, chances are this is not something that you have come across. Fortunately, a simple explanation can help homeowners discover why NATE certification is important to the quality of HVAC service they receive.

What is NATE certification?

NATE certification is an important indicator of a HVAC technician’s commitment to ensuring the highest quality services possible. NATE certification requires that a service technician pass two separate tests. The first test is an examination of their understanding of basic tools, safety procedures, principles of electrical components, heat transfer and a variety of skills. In addition to requiring a passing grade of 70% on the core exam, NATE certification requires the technician to choose an area of concentration or specialization and pass an exam on this chosen field. This specialization can range from air conditioning or air distribution to commercial refrigeration or gas heating. With a concentration on a specific area of expertise, the HVAC technician is better able to provide expert services.

Why Choose NATE Certified Technicians?

Homeowners often wonder if it is important to choose NATE certified technicians. It can be hard to understand the benefits of this extra training and accreditation, especially since all heating and cooling technicians are required to be licensed before they can perform HVAC services. The difference between a licensed HVAC technician and a NATE certified technician is that one has made the decision to further their understanding of issues pertaining to the HVAC industry. NATE certified technicians are certainly required to be licensed and carry the appropriate insurance, but they have also taken their training and willingness to learn as much as possible about their chosen field to the highest level.

In addition to choosing a NATE certified technician for general repairs and service, it is important to consider how they can provide exceptional AC maintenance. It is recommended that all air conditioners be serviced at least once each year. This preventative maintenance inspection is the ideal time to make any necessary adjustments and ensure your cooling system will be able to handle another summer. Schedule your maintenance service today and take comfort in a more reliable and energy efficient air conditioner this summer.

Lower The AC Or Turn On A Ceiling Fan: Which Is More Energy Efficient?

Have you been looking for an effective way to lower summer cooling bills? With the temperatures rising, many homeowners are anxious to find strategies to keep energy bills affordable; however, the thought of a summer spent in the sweltering heat with no relief is certainly not the answer. Fortunately, you do have options. A recent report by the New York Times outlines the cost of running an air conditioner versus simply using a ceiling fan. While a central air conditioning system, or even a window air conditioner, can provide a much cooler environment, a ceiling fan can help lower your cooling costs by working together with your air conditioner to keep temperatures comfortable while also saving you money.

The New York Times report stated that the cost of operating a typical ceiling fan for one hour was only 1 cent, while a central air conditioner would cost 36 cents per hour and a window air conditioner 14 cents. For most homeowners, the use of a ceiling fan alone might not be enough to provide a sufficiently comfortable indoor temperature but, using a ceiling fan in conjunction with an air conditioner can provide the same level of comfort as using an air conditioner by itself. The only difference would be in the amount of energy used as well as home energy costs. In fact, even a high efficiency air conditioning system can be used with a ceiling fan in order to lower energy consumption and monthly utility bills.

The report issued by the Times states that the use of a ceiling fan will allow you to raise the setting on your home’s air conditioner by up to 12 degrees, without any difference in indoor temperature from just running the air conditioner on its own. This certainly provides an opportunity to save a significant amount of money over the span of an entire cooling season.

An energy savings plan is an important part of reducing cooling costs this summer. Fortunately, a few simple strategies can make a big difference in your monthly energy bills. For example, when you want A/C money saving tips, it is clear that using a ceiling fan can help. Other strategies to add to your summer energy savings plan include making sure your weather stripping is in good condition, professional A/C maintenance, installing a programmable thermostat and minimizing sun exposure by planting trees or keeping blinds closed. If you want to save money this summer, now is the time to put together your energy savings plan.

Common Air Conditioning System Problems

Keeping your central air conditioning unit regularly maintained will deliver the best return on your investment. Although these units are built to go years without needing repairs, there are times when they don’t work as designed. By identifying the most common causes and solutions to non-working units, you can spend less time worrying and more time enjoying your home.

Refrigerant Leaks

Your air conditioner’s refrigerant level should match the manufacturer’s specifications and the unit should not be undercharged or overcharged. If your central air conditioner needs charged frequently, it can indicate a leak in the pipes that carry the refrigerant to the unit. Getting Freon charged is a simple, easy fix. Refrigerant leaks can also be harmful to your home’s environment, so it is essential that you have any leaks repaired immediately.

Sensor and Thermostat Problems

The sensors in your thermostat will largely determine the quality and consistency of the air blowing into your home. If the sensors on your thermostat are broken, it can cause your unit to behave erratically, cycling on and off and refusing to turn off. Checking thermostat to make sure the sensors are correct is the best way to diagnose and fix this problem.

Dirty and Damaged Components

When the air filters and coils become dirty and damaged, they can affect your unit’s performance. Wires can corrode and become damaged, causing the compressor and fan controls to wear out. This can mean a major repair down the line, so it is essential to have regular maintenance performed on your unit.

During the fall and winter months, debris like rocks, branches and leaves can clog your exterior unit, affecting its performance. During regular maintenance, your heating and cooling technician will troubleshoot your exterior unit, replacing any damaged hoses that might lead to weakened performance.

Problems With the Motor

If your unit is not blowing air at all, it could indicate a blown motor. To test the motor, go out to your exterior unit and check to see if the blades are rotating as normal. If they are not, it can indicate that the motor is blown. Motors often wear down before they blow out completely, so having your system maintained will catch this before it becomes a major problem.

Getting Regular Maintenance on Your Air Conditioning Unit

The key to enjoying a comfortable home year round is to schedule annual maintenance on your air conditioning system. A certified technician will visit your home and perform a complete diagnostic, ensuring that all parts are working correctly.

Don’t delay in scheduling your maintenance. In many cases, a certified technician can catch small problems before they become major repair issues. Schedule your maintenance at the beginning of the cooling season for best results.

Call your technician and schedule your annual maintenance today.
