What is a FURNACE?

Furnaces

What's up with the cold draft in my home?

When it comes to repairing and providing maintenance for furnaces, you can rest assured that your investment will be protected when you use One Hour Heating & Air Conditioning®.

A home furnace is a major appliance that is permanently installed to provide heat to an interior space through intermediary fluid movement, which may be air, steam, or hot water. The most common fuel source for modern combustion furnaces in the United States is natural gas; other common fuel sources include propane (LP), fuel oil, coal or wood. In some cases electric resistance heating is used as the source of heat, especially where the cost of electricity is low. Combustion furnaces always need to be vented to the outside. Traditionally, this is through a flue, which expels heat along with the exhaust.

Central Warm-Air Furnace: A central warm-air furnace is a type of space-heating equipment in which a central combustor or resistance unit--generally using gas, fuel oil, or electricity--provides warm air that circulates through ducts leading to the various rooms.

• A forced-air furnace is one in which a fan is used to force the air through the ducts. This is the most common in the Baton Rouge Area
• In a gravity furnace, air is circulated by gravity, relying on the natural flow of warm air up and cold air down; the warm air rises through ducts and the cold air falls through ducts that return it to the furnace to be reheated, thus completing the circulation cycle. (more common in northern climates)

The furnace typically is divided into three primary components:

• The burner (includes the heat exchanger, draft inducer and venting) - The flame originates at the burners and is drawn into the heat exchanger by the negative pressure produced by the draft inducer. The hot gasses produced by the combustion of the flame pass through the chambers of the heat exchanger and heat the metal walls of the heat exchanger. The gasses cool as they transfer the heat to the heat exchanger and are at about 120 degrees as they exit on a high efficiency furnace. The cooled gasses then enter the draft inducer blower and are pushed into the venting pipes. The exhaust gasses then are directed out of the house through the vent pipes.
• The blower and air movement - The blower creates a negative pressure on the intake side which draws air into the ductwork return air system and blows the air out through the heat exchanger and then into supply air ductwork to distribute throughout the home.
• Controls and Safety Devices - The controls include a gas valve, ignition control, ignitor, flame sensor, transformer, limit control, blower control board, and flame roll out switch. A limit control is a safety device that will open the electrical circuit to the ignition control and stop the gas flow if the furnace over heats. The flame roll out switch does the same thing if the flame was rolling out of the heat exchanger instead of being completely induced into it by the draft inducer.

Central furnaces should be checked for SAFE OPERATION and tuned-up annually. The best time is just prior to the heating season and prior to any regular use of your central heating unit or furnace. Furnaces left unchecked can be a major health, fire, and carbon monoxide hazard.

One Hour Heating & Air Conditioning® can help you make the best decision on which furnace maintenance service or plan is best for you.

Time Running Out on Federal Tax Credit for A/C

Up to $4000 in Incentives on New Central Air Conditioning & Heat.... Expires soon!

- Li Little Known Programs Helps us trade-in old, non-compliant Freon systems

This is great news for you and your wallet if your central A/C is over 8 years old or still runs on theOLD FREON.

Please allow me to explain…

As recently publicized by USA Today, it is a little known, and a somewhat inconvenient fact that Home Central A/C’s using R-22 (most commonly know as ‘FREON’) are no longer being made as of this past January 2010. Central A/C’s made today now use 'Puron' (R410A), a more efficient, environmentally sound refrigerant than the Old Freon. Puron has actually been used in Home A/C’s since 1996, but has only penetrated a small portion of the market because of a lack of urgency, until now.

This phase out step is a Federally mandated requirement originally set in motion by the Clean Air Act of 1992. You may even remember when this happened with our cars in 1992. However, unlike our cars, existing central A/C cannot use Puron because it is compressed at a much higher pressure and requires newer, different equipment.

This now leaves the majority of homeowners in the U.S. just like you, sitting on Obsolete, ‘Old Freon’ systems to cool their home.

My company, One Hour Air Conditioning, is one of North America’s leaders and Experts in Home Service, and I have put together an exclusive ‘National Comfort Compliance’ (NCC) Program to help homeowners replace their now ‘Obsolete’ FREON systems. This program takes advantage of three (3) separate, little known programs to help minimize the investment impact of installing a Compliant Central A/C system that is 2010 Federally compliant:

#1 - A $1500 Federal Tax rebate

Good timing for you. As part of the American Recovery and Reinvestment act, a credit of up to $1500 has been made available for qualifying systems being installed, many of which qualify under the NCC Program. Better yet, we provide written certification and provide all necessary paperwork to take full advantage of this little used program which ends 12/31/2010!

#2 - up to $2700 NCC Cash Trade-in allowance

There is normally no trade-in for older, Freon style systems, but I am willing to give you up to an additional $2700 trade-in allowance right off the top toward any qualifying system investment.

and, Last but not least…

#3 - A special Home Improvement line of credit

You don’t even have to pay me right away. I have set up a terrific home project line of credit plan with one of America’s #1 retail financers for NO MONEY DOWN along with either 12 months no interest OR a low 9.9% APR option on all system options.

Energy Efficiency Guarantee

"These Brand New compliant systems are a dream! I’m so confident you will save at least 25% on your cooling and heating bills (most project to save more like 30% to 50%), that I will pay you double the difference for a year if you don’t! "

If these central air conditioning and heating systems were not among the best on the market, I couldn’t afford to make such a promise.

What To Do Next

Give me a call today and take advantage of our exclusive National Comfort Compliance (NCC) Program before the deadline. I can be reached at 225-752-0001. We can schedule for a Technician to come out and perform a FREE, no-obligation Compliance, and Energy analysis. At that time we will be able to share all program details and the cost on a compliant system that meets your needs and budget, a system of your choosing.

Why you must act soon

Do not wait to call me until your system breaks down at the most inconvenient time, and you will virtually be required to be compliant, with little or no incentives. Again, give me a Call at 752-0001today.

Also, the NCC Trade-in allowance, which comes out of my company’s pocket, is limited to the first 96 compliant system installations in before September 30th, 2010

Finally, the deadline for the NCC program is Friday, July 31st 2010. This deadline has been extended and set just in time for the end of the Federal tax credit program. If you think you may need a new central A/C anytime in the next 3 years, if your bills are over $200 per month, or if your old system runs on the Old Freon and has been nickeling and diming you to death....you cannot afford to wait!

Give me a call now at 752-0001 and I will set an appointment for your no-obligations survey

Air Conditioners

Is your home being cooled properly?

Each year we take thousands of calls from customers who need help with air conditioner repairs or installation. We understand the importance of feeling comfortable in your home’s climate. Air conditioning is a process that controls the filtration, air movement, temperature and humidity of a given environment. Air conditioning is always associated with the cooling and the dehumidification process of air, and is therefore identified with refrigeration equipment. A residential central air conditioning system keeps your entire home cool in the warmer months, while it helps lower indoor humidity levels. Air conditioners can be centralized with ductwork to carry the cooled air to various rooms or individual units that cool specific areas.

How Does Air Conditioning Work?

Most people think that air conditioners lower the temperature in their homes by pumping cool air in. The actual process removes warm air from your house and cycles it back in as cooler air. This cycle continues until your thermostat reaches the desired pre-set temperature.

System elements include a compressor, a fan, condenser coil, evaporator coil, and a refrigerant. The unit extracts heat from indoor air and transfers it outside, leaving the cooled indoor air to be re-circulated.

An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant to provide cooling. The mechanics of the refrigerant evaporation cycle are the same in a refrigerator as in an air conditioner. A compressor compresses cool refrigerant, causing it to become hot, high-pressure gas. This hot gas runs through a set of coils so it can dissipate its heat, and it condenses into a liquid. The liquid then runs through an expansion valve, and in the process it evaporates to become cold, low-pressure gas. This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air inside the home.

Three elements which make up a split central air conditioning system, are:

• An outdoor condensing unit
• A matching indoor air handler
• Ductwork to transfer the cooled air throughout the home

Standby Generators

Generators

Help! my electricity has gone out.

One Hour Air Conditioning's 'Smart Power Division' electric generator service is one of the most comprehensive in the business—because we know the importance of staying connected and staying safe when the power goes out. Whether we’re installing a new generator or servicing a backup generator, we’ll assess your needs and make sure that you have peace of mind.

What is a Generator?

Generators are standby devices which can supply electricity to your home during power outages. During a power outage, it allows you to continue to operate essential appliances such as refrigerators, computers, heating and cooling systems and lighting.

The process that generators employ involves converting mechanical energy into electric energy. This is the same process that is used, on a larger scale, to produce electricity for entire communities by your local utility provider. In essence, a spinning shaft powered by an engine is used to produce a magnetic field through a coil, which in turn produces an electromotive force.

Choosing a generator

Home generators can be either portable or stationary. They run on a variety of fuels including, gasoline, diesel, natural gas, propane and oil. Generally, gasoline portable models are less expensive to purchase. However, they typically have shorter run times because of the need to refill the tank, if used constantly. And if the outage is due to wide spread outages or severe weather conditions, gas pumps may not be operational. Natural gas with its constantly available supply, tend to be the more reliable for stationary models.

The main differences between stationary and portable models are in their connection and activation. A portable unit has to be moved to your location, filled with fuel and then connected to fuel line, manually started then connected to your load requirement. Portable units allow for easy storage when needed. A stationary unit can start immediately and is usually already wired to the home and the fuel source. A determining factor as to which works best involves how much space you have for the unit, since a stationary unit may require a concrete pad.

Generators usually come in sizes that range from an output of 1 kilowatt (kw) to over 100 kw.

Choosing a fuel type

Your choice of fuel should be determined by the fuels available in your area. The more remote your location is, the bigger the concern for having available fuel will be. As mentioned earlier, gasoline, diesel, fuel oil and to an extent propane, have limited availability and delivery in extreme circumstances. Natural gas can also be limiting if you are not connected to their distribution system.

Wired Systems

A standby power backup device connects to the house wiring through a transfer switch. The transfer switch prevents ‘backfeeding’ into utility lines, which is dangerous and illegal. It also protects the device from damage caused by the utility company applying voltage to your house wiring while it is operating. These switches can either be automatic or manual and should be rated to carry the larger of the maximum load of the residence or the full output of the generator.

Limitations

If your generator is intended to supply only a portion of your home's electrical load, a list should be made of the electrical equipment to be powered during an outage, for example; appliances, lamps, furnace blower motor and the like. Compare the total wattage of the equipment to the total wattage output rating of the generator and do not exceed it.

In any case of installing stationary generators, or performing electric generator service, a licensed One Hour certified Generator technician should perform all the electrical connections to avoid any problems. Additionally, all wiring, gas connections, and equipment must comply with local, state and federal laws or codes, inspected and adhere to the rules and regulations of your local utility.
