A furnace heat exchanger is an intricate piece of the furnace. It is made up of metal sheets with tubes and cylinder like notches. It is supposed to take fire and remove it from the air stream. One thing that should be analyzed is how strong of heat exchanger that you have. If your exchanger is damaged, it could be dangerous health-wise for everyone who lives inside the house.

If you have a damaged exchanger, the air stream will contain fire has been rolled out within it. You want to make sure you have a durable heat exchanger and one that doesn't rust easily.

Good quality heat exchangers are a must as well as one that doesn't rust. Picking a furnace heat exchanger that is of poor quality will cause the coil of the air conditioner unit to leak and ruin the material, which could lead to a fire. Another item to prevent this is the combustion blower with an 80% efficiency level or one that has a condensing furnace with an efficiency level of 92%.

Having either of these, a blower or a condenser can prevent flue products from coming into the air stream. You will have to occasionally inspect the heat exchanger. The most common cause of damage is dropping during shipment, damage when its installed, it overheating or poor quality control during testing.

To be on the safe side, always purchase a furnace brand that is able to give you step-by-step guidelines and is able to provide you with helpful tips and things to look out for after purchase. Do not buy name brands that have unclear safety standards. You double check your furnace's information with the US Consumer Product Safety Commission's site online. If you start to notice a discoloration or a bluish color, you will need to immediately change out the furnace heat exchanger. The original color should be a silver-chrome color.

It seems that everywhere we look these days the costs associated with daily living are constantly rising. One area that affects most people is the rise in energy bills. In the last few years, the price of home heating oil and natural gas has increased quite significantly because of the increased demand on the world's oil supply. As the costs of gas increases, the task of paying for our energy bills becomes quite difficult. It has become essential to shop around when looking for a gas supply company. When one searches for a gas supply company, there are a number of factors they should take in to account before selecting a company.

Gas powered central heating or gas to run a business such as a restaurant is normally cheaper than electricity or oil. When choosing a gas supply company, consider the following tips:

1. The gas supply company should be committed to safety and reliability. Find out what type of underground lines they use to run the gas and if the lines are safe from leakage. That is, are they the most durable lines available? Ask the company if they are a certified and licensed gas distributor.

2. It is important to compare prices from a number of gas supply companies. For instant each quote from a company should include their total rate which is broken down into the Gas Cost Recovery Rate, A Gross Receipts Tax Rate, and Transportation Costs Rate.

3. It is essential to review and thoroughly understand the gas supply contract. This includes the terms and conditions of the contract. If you are in need of clarification, it is important to ask the supplier. As well, some companies give customers a pipeline charge. This is an unnecessary charge for a home, so if the company says they charge a pipeline fee; look elsewhere for a gas supply company. For businesses such as a restaurant, a pipeline fee may be standard practice.

4. Questions you should ask the gas supply company include: How long will the rate remain in effect? Does the price depend on how much gas one uses? Is there a cancellation fee if I cancel the agreement before the end of its term? Is the price fixed or does it change? Is there a customer incentive for signing up? Is there a budget plan? What happens when my contract expires? Are there any built-in price increases or decreases? What is the price per hundred cubic feet (ccf) or thousand cubic feet (mcf)? It is important to be aware that some companies use a floating price each month, other companies apply a fix price for the entire year, and some charge you a flat rate. A low fixed-price is a good choice.

5. Once you have chosen a gas supply company, that company will notify your local utility. Once confirmed, your local gas utility will send a letter to you substantiating the supplier you have chosen.

When you are looking for a gas supply company, whether for your home or your business, it is important to do your research and comparison shop so that you know you are getting the best service at the best price.

This is a question that pops up all the time during the warmer months of the year. A Homeowner is in need of a new Air Conditioning System, and has to decide whether to replace the furnace at the same time or not. Changing the furnace is not required unless you are making changes to the cooling capacity, however, the benefits of doing a full system change-out are huge, if the furnace is more than 8-10 years old! As a matter of fact, if you just ASK the person who is quoting your AC job, they may just give you a furnace AT COST, just to get the job!

When You MUST Change the Furnace

As stated above, the furnace may not always need to be replaced, but there are times when you MUST change out the furnace.

Are You Increasing Air Conditioning Capacity

The blower inside your gas furnace is designed to move a specific amount of air through your duct system. This is measured in CFM, or cubic feet per minute. That volume of airflow is matched to the cooling capacity of your air conditioning system for optimal efficiency. A Ton of cooling capacity needs a minimum of 400 CFM to work properly and avoid freezing up! For example, a 2.5 ton air conditioning system requires a minimum of 1000 cfm of airflow. If you increased the cooling capacity to 3-tons of AC, your furnace blower MUST move at last 1200 cfm.

When You Don't Have to Change the Furnace

If you are not changing the size of the AC unit, there is literally no need to swap the furnace out unless its broken! The AC circuit is completely independent of the heating cycle, and aside from replacing the evaporator coil that mates with your furnace, if it's not broken, it is NOT required to be replaced! That said...

You WILL Save Money Doing A Full Change-Out!

Its just simple economics... the Contractor is going to be there and they are going to have most of the area cleared out for the new evaporator coil. In most cases, changing your furnace will only add 1-2 hours of labor to their project along with the cost of the furnace itself and some general sheet metal work. His crew is already there and if he is reputable contract having the unit inspected, why not just get it all done at once?

• Typical AC ONLY Replacement Cost in July - $2900 - $5000 (Low Estimates)
• Typical Cost of a Furnace ONLY replacement in Mid Winter - $2900 - $4000
• Typical cost to add the furnace in Mid Summer... $1000 - $1500

As you can see in the basic and rough estimates above, you can save MORE than a thousand dollars getting the furnace replaced at the same time! Unfortunately, if you wait until winter, it does not work the same way...

How to Get a Furnace for FREE or Dealer Cost!

When your Contractor comes out and quotes your replacement Air Conditioning System... let them get all the way through their presentation and ask them one question: "How Cheap Can you Install the Furnace for, if I sign RIGHT NOW?" If they add $3000, tell them thank you and let them leave! Even the MOST EXPENSIVE Gas Furnaces on the market cost less than $2000 at contractor rates, and they must not want the job that badly!

It is however very fair for them to add cost, plus 50% markup... which is MUCH lower than they will quote you in the winter time!

Approximate Gas Furnace Costs to a Dealer

There is alot of varation in pricing models to different volume dealers around the country, but these general guidelines apply.

Brands like Carrier, Trane, American Stanard Amana, and Lennox will usually be higher than others. Goodman, Bryant, Payne, Frigidaire and others will be lower cost.

80% Efficiency Furnaces will range from $400 - $1200, depending on brand and features.
90% or Higher efficiency units will range from $650 - $2000, again, depending on brand and features.

One way or another, you will always save money by installing the furnace at the same time!

This has got to be one of the most common questions I get at the Web HVAC website! The truth is... A Gas Furnace is actually a key component in a Hybrid Heating System!

What is a Hybrid Heating System

To better understand how a Gas Furnace fits into a Hybrid HVAC System, you need to understand there are 2 key functions to a central HVAC system, Heating and Cooling! As it relates to a Hybrid System, the heating portion is all you are really interested in, since the cooling will remain the same, regardless.

Hybrid Heating Systems give you the ability to decide how you wish to heat your home, by providing 2 sources of heat!

1. Gas Furnace, Preferably High Efficiency!
2. Heat Pump Condensing Unit, Preferably High Efficiency!

How a Hybrid Heating System Works

In the previous paragraph, we found out that in a Hybrid HVAC system, you have two individual sources of heating for your home. A Gas Furnace and a Heat Pump. Depending on the cost of utilities in your area, it may be more affordable to run one or the other, at different times. The variable of cost may even change at different times throughout one single day!

Scenario 1 - High Cost of Natural Gas

Assume for a minute that this year, natural gas costs rise considerably, yet the cost of electricity remains low. In a scenario like this, you would tell your heating system to use the electric heat pump for as much of your heating needs that it will handle, usually down to about 32 degrees outside.

You step over to your thermostat and program it to read the outdoor temperature. When the temp outside drops to 32 degrees, the heat pump will automatically switch over to the gas furnace for the heating of the home.

Scenario 2 - High Cost of Electricity

In this second situation, you are one of the fortunate ones that gets super cheap natural gas in your area! In this case, you reverse the above mentioned strategy, and instead, tell your hybrid heating system to use natural gas as much as possible for your heating needs, never really using the heat pump at all for the purpose of heating your home.

Hybrid Flexibility Pays Off Over Time!

Why anyone would install a simple AC Condenser outside their home nowadays is beyond me! Heat Pump units only cost about 50% more for the equipment, but can save you a significant amount of money over the course of a lifetime with your unit! Ex: 2.5 ton AC only unit costs about $800, the same size Heat Pump Condensing Unit costs about $1200. That extra $400 in the cost gives YOU control over how you heat your home in the colder months!

Even though one utility may be cheaper right now, history shows that the costs will fluctuate over time. Having the ability to make your own choice is priceless!
