Why Should You Upgrade to a High-Efficiency Gas Furnace?


Having a gas furnace in your home is essential for your comfort especially if you live in areas affected by the cold. And while it is working well, most people are reluctant to change it. Of course, the disruption of changing your furnace, as well as the cost are major factors, but even bearing these in mind, upgrading your old gas furnace to a new high-efficiency one can be worth it.

If you are already thinking about getting a new furnace, then the choice has already been made for you. There are many benefits to having a high-efficiency gas furnace, including:

  • It can save you a lot of money thanks to its efficiency
  • It is better for the environment
  • It will work perfectly, offering you the best quality heating

A high-efficiency gas furnace is specially designed to limit the amount of wastage, which has previously been impossible in older furnaces using some new technologies and techniques.

The AFUE (Annual Fuel Utilization Efficiency) is a measure of the efficiency of a furnace – based on the amount of gas exhausts, which are released. The measure is a percentage of the amount of energy used for heating – for example, a 75% AFUE means that 75% of the energy is used for heating and 25% wasted (through heat exhaust). A good AFUE furnace can have an AFUE of up to about 96%.

Through a reduction of wasted energy, your house will stay warmer with a lesser amount of energy used – and wasted, therefore reducing costs and lessening the impact on the environment.

There are some ways that a high-efficiency gas furnace can improve its efficiency, including:

Automatic Vent Damper

An automatic vent damper cuts the fuel pipe when it is not in use. This means that fuel will not be wasted, significantly increasing its efficiency. The auto vent damper is a relatively new technology, which is an excellent way of improving thermal efficiency.

Electronic Ignition Technology

Older gas furnaces used to use a pilot light, which was lit at all, times, wasting massive amounts of energy. The newer electronic ignition technology creates a spark, which is then used to ignite the gas, only when it is needed, and therefore cutting out on a massive amount of wasted energy.


The newer high-efficiency gas furnace controls and induces the airflow so that it doesn’t freely circulate. This is not only useful in cutting out wastage and improving efficiency, but it also makes the whole system a lot safer.

When you are choosing a high-efficiency gas furnace the two most important factors that you should be thinking about (other than the cost) is having the highest efficiency rating as possible, and making sure that it is fitted correctly. After all, the more efficient your furnace, the lower your bills will be, and reduce the impact on the environment. Make sure that you get a responsible, professional company to fit your new furnace to avoid potential issues and maximize efficiency.

Worst I’ve seen in Las Vegas, thats why you call licensed professionals.

When your Heating or Air Conditioning system malfunctions, don’t just call your friend or cousin bobby’s friend either. Call a licensed professional that has a proven track record and has a licensing board to answer to.

Last winter I went to a no heating call to help a cold Las Vegas citizen. This man told me “ the guy who looked at it before you took some parts to look for replacements, but I can’t reach him now”. So what I found on the roof was absolutely shocking. The company or man had stolen this man’s heat exchanger and left his heating system in shambles. Here is the Video

What did I run into

Calling an un-licensed company or person leaves you dry when there’s trouble. When you allow someone to work on your home, calling a licensed professional who cares about his reputation has mostly 5 or 4 star reviews or we could say a proven track record of happy customers. Calling a company like this guarantees they will act in a way to avoid a complaint. And, that means treating you with respect, answering the phone and being on time. But mostly speaking the honest truth and in the event that there was an issue that company would most likely jump to make it right before a complaint is recorded.

Here is a list of things I would advise you look at before choosing a company to call to your home.

1.       Make sure they are A or A+ with the better business bureau.

2.       Make sure they have mostly 4-5 star reviews on Google because you can’t fake those.

3.       Make sure they send you a technician and not a salesman, (if he shows up clean as a whistle and doesn’t bring his tools. Then he didn’t come to fix anything.

4.       If they do not answer the phone professionally then just move on.

5.       If they can not send you a technician today then move on, there are others who offer same day.

Winter Time Safety Check and Tune

With the cold coming, now’s the time to have your homes furnace or heating system cleaned, checked and tuned. Heating system can malfunction leaving you in the cold and in need of a heating repair company or even worse, kill. Yes a heating system can kill be burning down or by leaking carbon monoxide into the air stream. So keep an eye on these 3 things to make sure your home is safe and ready for winter.

  1. Replace your air filter; an air filter is cheap but much needed. If you don’t stop dirt at the filter, it will flow in and clog you condenser coil causing the airflow to be restricted. This restricted airflow will raise the temperature when the heat is on. High temperatures are not something you want in your attic so please replace your filter on a regular basis. I say every 1-3 months if after a month your filter is still clean then start giving it 2 but never go longer than 3 months.
  2. Pay attention to random or unexplained headaches, these could be caused by the furnace. Yes every time the furnace is heating the home it is generating carbon monoxide which is supposed to be sealed inside a metal heat exchanger and vented out the flue vent. But, heat exchangers crack and allow the carbon monoxide to flow into the air stream.
  3. Check your flue vent, be sure it’s clear and no birds have made their nests in it, or even died and clogged the vent. That happens more than you’d imagine and when the nest or bird clogs the vent the carbon n monoxide can’t escape so it flows into the air stream again.

Some of these things you can watch for at home and your filter is your responsibility but you need to call a licensed professional to come for a home visit and inspect your system on a regular basis. We will come right before winter clean, inspect and tune your heating system and stop your trouble before it happens.

If we inspect a furnace and find a crack, it’s not money were saving it may be your life. So be smart call now and get a winter heating preventative maintenance or even better sign up for our no breakdown no trouble club and well inspect your home twice a year. Once your part of the club and we have inspected, if it ever breaks we come back for free plus the thermostat is always free for our club members so get covered now by a Las Vegas Air Conditioning No Breakdown Iron Clad No trouble club.

Why is my bedroom always hotter than the rest of the house?

To fully understand why some parts of most homes are either too hot or too cold. Or why one room is always hotter than the rest. You first need to understand what heat load is. Heat load is how much cooling or heating is needed to properly heat or cool a particular room, usually measured in BTU. Everything from square footage, how many square feet of windows are in the room and what side of the home they are located on play a factor, ceiling height, appliances and your zip code come into play. Most contractors are not properly sizing furnaces or air conditioners because they size based solely on square footage which does nothing for un even temperatures and they do not run the proper load calculation tests. Now, some areas of homes have a lot more heat load than others. Some examples are rooms with east or west facing windows, rooms with high ceilings or even rooms over the garage are always uncomfortable because it has heat coming up from below and usually 2-3 of its sides can be to the outside. Any of these conditions would cause that room or areas to warm up faster than other areas in the home with less heat intruding in or being generated.

Now that you understand how some areas warm up faster than others. Ask yourself is the problem that the unit runs or is it that the unit doesn’t run enough. Imagine if your motor stayed running longer always circulating air through the home. The rooms with more heat load would never get a chance to warm up since the entire homes air would always be mixing. The result would be an entire home with the exact same temperature. So, the short explanation is a single speed motor that turns on 100% and off then on 100% again is one reason and also the most overlooked problem in the US causing uneven temperatures in rooms. It’s the off cycle that allows the rooms to warm faster than the others.

Ductwork is also a major problem in the US as 93% of homes have major duct leakage. That number is taken directly from the US department of energy website and also energy star website.
In the first paragraph I explained how a heat load calculation determines how many btus are required to keep a room cool or warm. The ducts are sized to deliver that exact amount heating or cooling. But then 93% of ducts leak so wherever you leak air into the attic is less delivered into the home. Basically we size a duct to deliver enough air to cool a room but after leakage there may not be enough left to properly cool or heat a room.
A sure sign of leaky ducts is to open an inside door and look at the hinges if you see a black dust trail, you have leaky ducts.
The trail is caused by uneven pressures because the return is sucking out say 2000 cfms of air from your home then you pay to heat, cool and filter that air that then gets blown into the leaky duct system. So if 10% of the air leaks into the attic your only delivering 1800 cfms back into the home so its now in a negative pressure causing air to be pulled in through anywhere it can find it. Air will always take the least path of resistance.
Leaky duct are major causes of poor indoor air quality, drafts and uneven temperatures, allergy symptoms and even shorter equipment life it could also more then double the HVAC portion of the energy bill.

Some tricks for home owners to fix some of these situations are:

Install a Variable speed motor $500.00 for the part plus 2-3 hrs labor. This motor will save them approximately 50% of what they’re current motor uses it will also run quieter and stay running longer circulating air through the entire home always blending the home air and keeping temperatures even. Most local power companies are urging homeowners to get variable speed motors installed and most are even offering rebates that could pay 100% of the cost of motor.

There are many ways to fix the duct balancing problems. A contractor can install dampers to push more air to the areas that need more air this can be done in less than an hour. Something a homeowner could do is to remove the vents of rooms that are getting too much air and restrict the vent or duct pushing more air to the other areas of the home that are not restricted. A homeowner could also crawl through their own attic and paint all the duct connections with duct sealant ( can be bought at any home depot or lowes for around $40 a bucket I suggest 3-4 buckets to seal an entire system. Just simply cover every connection and when it dries the entire duct system will be sealed and we will no longer be drawing in that hot dirty un-filtered attic air.

Sealing duct work is hard and dirty but if a homeowner is willing it can be done by them or any educated contractor could do it for around $800.00 But this will lower the energy bill around 5%-30% depending on the size and number of leaks in they’re system.

If a homeowner was to get a variable speed blower motor and completely seal all they’re ductwork, they would have a home with even temperatures, clean air, and energy costs could go down by as much as 25%

Other ways to save energy is to:
• Try and keep all doors closed and keep window coverings closed as much as possible especially those east and west facing windows.
• Installing a smart thermostat can save money by turning the unit off when its not being used. Always remember every time we can shut off the compressor is money saved. A programmable smart thermostat can shut your system down when you forget.
• Get your system checked by a professional at least once a year
• Spray the outside condenser coil with a garden hose once a year (will lower power bill)

F.Y.I. we have variable speed systems with variable speed cooling and heating capable of keeping the entire home to 1/10th of a degree to where they set the thermostat and that’s year around it does this by never shutting off instead it will just rev down to 25% and keep the air moving there’
s no way to have a higher level of comfort and energy efficiency as when reved down to 25% the motor is using 85 watts of power less than a 100 watt light bulb.
We have many more tricks and energy saving solutions. I’d love to share them with you anytime.
Our company and family has been servicing air conditioners, heaters, refrigeration since 1969 we are licensed, insured and many of our technicians actually teach air conditioning at the college on there spare time.
I also wrote a how to book for ac repair. It will be published soon on an app and online. The repair matrix is a follow your own ending format basically it can take any homeowner or service professional from start to finish, how to diagnose an air conditioner and repair the problem. After 20+ years repairing air conditioners I realized I had a procedure, an order if you will so I put it on paper as an if this then you do this format. The repair matrix will revolutionize this industry and no longer will a contractor be able to lie to homeowners because with this app the homeowner will be able to easily and within 7 steps or less fix or at least diagnose there own ac.
