13 best high efficiency furnaces

High-efficiency furnaces are heating systems designed to provide effective and energy-efficient home heating. They are related to HVAC (Heating, Ventilation, and Air Conditioning) systems and are used to generate heat during the colder months. Here's what you need to know about high-efficiency furnaces:

  1. Efficiency: High-efficiency furnaces are known for their energy efficiency. They are designed to convert a significant portion of the fuel they use into heat, reducing energy waste and lowering utility bills. These furnaces typically have an Annual Fuel Utilization Efficiency (AFUE) rating of 90% or higher.

  2. AFUE Rating: The AFUE rating is a measure of a furnace's efficiency, representing the percentage of fuel that is converted into usable heat. For example, a furnace with a 95% AFUE rating converts 95% of the fuel into heat, with only 5% wasted as exhaust.

  3. Condensing Furnaces: High-efficiency furnaces are often condensing furnaces. They utilize a secondary heat exchanger to capture heat from the combustion gases, which would otherwise be lost in conventional furnaces. This heat is then used to heat the home, increasing efficiency.

  4. Energy Savings: The improved efficiency of high-efficiency furnaces can result in significant energy savings over time. While they may have a higher upfront cost, the reduced energy consumption can offset this expense.

  5. Environmental Benefits: Due to their reduced fuel consumption and lower greenhouse gas emissions, high-efficiency furnaces are considered more environmentally friendly than standard furnaces. They help reduce the carbon footprint of heating systems.

  6. Variable-Speed Blower Motors: Many high-efficiency furnaces come equipped with variable-speed blower motors. These motors can adjust their speed to match the heating requirements, providing consistent and efficient airflow while reducing energy consumption.

  7. Dual-Stage or Modulating Burners: Some high-efficiency furnaces feature dual-stage or modulating burners. These burners can operate at different levels of heat output, matching the heating needs of the home more precisely and enhancing comfort.

  8. Proper Sizing: To maximize efficiency and performance, it's crucial to properly size a high-efficiency furnace for your home. A professional HVAC technician can help determine the right size based on factors like square footage, insulation, and climate.

  9. Regular Maintenance: Like all HVAC systems, high-efficiency furnaces require regular maintenance to operate efficiently and safely. This includes changing air filters, cleaning components, and inspecting for any issues.

  10. Installation: Proper installation by a certified HVAC technician is essential for the optimal performance of a high-efficiency furnace.This ensures that all components are correctly connected and calibrated.

  11. Air Quality: High-efficiency furnaces can improve indoor air quality by effectively filtering and circulating air, which can be particularly beneficial for those with allergies or respiratory issues.

In summary, high-efficiency furnaces are energy-efficient heating systems that provide effective home heating while minimizing energy waste and environmental impact. They are equipped with advanced features like condensing technology, variable-speed blower motors, and modulating burners to enhance performance and comfort. Proper sizing and professional installation are crucial for getting the most out of these systems.

Question: What size of pvc pipe is required for the vent and air intake? (for model #gmss960603bn
Answer: yes
Question: What is the maximum ESP for this unit
Answer: I’m see no reason that it wouldn’t fit your power washer, it’s a standard size and style attachment. And in the “very slim” chance it didn’t, Amazon is the best at helping its customers with any issues they may encounter.
Question: Can you adjust fan speed
Answer: If you need water only, you can remove the foam cannon and replace it with water nozzle. Thank you very much.
Question: If i import this to canada and have it installed by a licensed hvac professional will the warranty be covered

Question: will these filters work for cloth medical mask? looking for a safe filter (no fiberglass) for healthcare workers

User questions & answers

Question: Can I replace my 16×25×4 filter with this filter
Answer: The 4 stands for 4 inches wide. The 1 stands for 1 inch wide. These measurements are in inches. Length x width x thickness. Beware, there appears not to be an industry standard on the actual measurements. I purchased a 20x25x4 inch generic filter that was actually 19 5/8" x 24 1/2" x 3 3/8". It was too small to provide an adequate seal so I returned it. Your best bet is to measure your filter then, look for or request the manufactures actual measurements.

User questions & answers

Question: is this model an updraft
Answer: It runs on natural gas. I don't know if there is a conversion unit available. A Goodman representative would be able to answer that question.
Question: Does this run on natural gas or propane? Is there a conversion unit available
Answer: Yes, you can take return air out of the bottom or either side.
Question: My air return in on the bottom, not the side. Will this unit work for me? (furnace closet is in an indoor heated hallway
Answer: You'll need some wire to hook it up, and you'll have to build a return box for it to sit on, because return is on very bottom, and you'll need a thermastat if you don't have one already as well as a place to vent the exhaust along with exhaust pipe. Other than that I installed this. New gas line, wired it up, built return box along with running all my duct work and connecting it to vents downstairs and upstairs in about 10hrs out of the box. And this was my first time ever doing anything like this! So you should have no problem. FYI if you have an old furnace, there's a chance the thermastat wire runs into a breaker box and converted to 24 volt before entering old furnace!! If this is the case you can just bypass all of it because this furnace gas it's own 24v supply for thermastat( and if it is old thermastat you'll only have 2 wires to hook up, only on thermastat that runs your central air will you have to worry about hooking up more! See the instruction booklet for wiring diagram!(wich for some reason was inside the furnace!! Had to remove both front covers to get to it) you'll have to remove them either way during installation to get to everything. Oh yeah you'll need a few pcs of gas line because female adapter is inside funace I just brought mine straight out the top and u'ed it around and connected gas line" mega lock is your Freind"!!!
Question: what eles we need to make it run, not asking the air pipes to the room and not the gas pipe, but .what else
Answer: It is a relatively inexpensive bow. I wouldn't expect any warranty support from manufacturer. Depending upon which seller you buy from you may have some options to return a defective item if you should happen to get one. My older daughter has been using this bow for 7 months now. She plays a lot. This bow have been a great performer for her.

Question: you are advertising it as By Rheem but some questioners say it is a Rotom, which is it
Answer: We are using this in a 1850sq ft home but have a gas fireplace and only have heating ducts on the ground floor. It does maintain a reasonable 60 degrees when we are away and seems to handle that work load very well. Be aware this is a downdraft furnace amd the actual size of the case was small compared to the removed unit. I had to modify the heat outlet and fresh air inlet duct work to accomodate thr smaller case.

Answer: There a quite a few variables that go into proper sizing which can be best answered by a licensed technician, however, 60K is a bit undersized for that large of a home.
Question: Will the "Furnace Draft Inducer Blower FB-RFB241" fit a RHEEM model# TG9S100C16MP11A
Answer: The "downward" flow is a literal air direction as it leaves the furance. The bottom of the furance is open and meant to be where the unit ties in to your existing heater duct work.

Question: When I installed this, it seemed very snug. Are filters supposed to be snug? The label on our unit says this is the correct size

Mine is, and I have had no problem in the seven years I've been using it.You need to make sure that the filter required is a 4 inch pleated filter and you must make sure that you have the arrows going in the right direction i.e. follow the arrows that are on the top of the filter and That will be the direction of your airflow. If you're having issues other than this you might want to have it checked out . BTW-how old is your furnace and how often do you change the filter?

User questions & answers

Question: What is the actual size of these precisionaire 16x25x4.5? they work in my furnace but i would be curious to know if it matches the oem filter size
Answer: We replace our filter every 3 months. I replaced them twice a year until I had a biger system installed. We had an Amrstrong 16 ser system put in and now we replace the filter every 3 months. I would recommend checking you filter monthly by holding it up to a light and see how dirty it is. You environment plays a big par in when to replace the filter.
Question: Will the 4" fit in a 4.5" furnace
Answer: I’m not sure if they contain fiberglass. All the literature I’ve found states that they are much more efficient than the typical 1” fiberglass filter, but it doesn’t specify what THIS filter is made of. I also can tell you fiberglass filters are typically cheaper and not pleated. These four inch filters are pleated.....so I’m going to guess that they do not contain fiberglass. But that is a guess.

NaturalAire Choice Allergen Air Cleaner

The NaturalAire Choice Allergen Air Cleaner removes harmful particles to keep the air in your household or office clean and fresh. This standard replacement filter is suitable for a wide variety of HVAC systems and holds a MERV (Minimum Efficiency Reporting Value) rating of 8, which means it is third-party certified to effectively reduce up to 85% of household dust and particle debris. MERV ratings provide a standard comparison of air filter performance. A higher MERV rating signifies greater efficiency and increased protection against airborne particles. Breathe easy knowing that Flanders provides the best quality product to keep your home’s air pure.

Upgraded Air Cleaner Technology

The NaturalAire Choice Allergen Air Cleaner achieves high efficiency at low pressure drop. This proprietary media combines with Flanders’ unique V-pleat manufacturing design to give you the highest performance pleat available on the market today. The deep V-pleated panel filter offers a larger surface area for catching impurities and reducing air resistance. Don't compromise on efficiency, quality or satisfaction with an air filter from Flanders.

Reduce Harmful Allergens

With a rating of MERV 8, the NaturalAire Choice Allergen Air Cleaner captures up to 85% of floating air particles as small as 3.0 microns – this is impressive when one considers that a strand of human hair has a width of 50 microns. The NaturalAire Choice Allergen Air Cleaner works to eliminate carpet fibers, pollen, dust mites, household dust, pet dander and mold spores from your indoor air for up to 1 year before replacement, supplying long-lasting clean, fresh air and offering a real difference that you can feel.

Measuring Your Air Filter

Choosing the right size filter is important for keeping your home's air clean. An improperly sized filter will bend if it is too large or fail to catch impurities if it is too small. To determine the dimensions of your filter, measure the width, height, and depth separately in inches of the space where the filter will go in your HVAC system. This will give you three measurements. For instance, a filter with a width of 20 inch, a height of 20 inch, and a depth of 1 inch will give you a filter with dimensions of 20x20x1.

The Importance of Changing Your HVAC Filter

When it comes to extending the life of your HVAC unit, changing the air filter is crucial. Clean air filters are essential for the overall performance and long-term protection of your unit – an old air filter reduces your HVAC unit’s air flow and decreases energy efficiency. This can damage the equipment, as a dirty or clogged air filter can lead to overheating or impair an evaporating mechanism in a cooling unit, further reducing air flow and causing your HVAC unit to run slower and less effectively, costing you money and leaving harmful and unpleasant pollutants in your home or office’s air. For cost-effective heating and cooling and the highest possible air quality, the NaturalAire Choice Allergen Air Cleaner is a choice you can feel secure about.

User questions & answers

Question: The description states "filtrete micro allergen defense filter, mpr 1000..." but the picture shows mpr 1550....which one are you buying
Answer: The size is as stated. there is also a 16x25x5" available; the specs that came with your furnace should give the size recommended.
Question: What are the dimensions of the filters? The product image shows 4" deep (20x25x4), but the option is only 1" deep (20x25x
Answer: sorry , I'm not sure
Question: Never had an air conditioner or furnace so I have a rather silly question. How can I tell when the filter needs changing - dirty on the backside
Answer: Made of stainless steel. The quality is good, I recommend buying.
Question: what is the Merv Rating and how do you convert 1550 MPR to a Merv rating
Answer: Kim,when I attempted to insert the filter (25x20x4) it did not go in easily. I m sure some schrunching has taken place. I measured the filter before insertion and noted from the outset that 4" measurement was greater than my furnace cavity. I will keep it in place until it gets dirty but will not replace the Honewell Filter from Amazon again. Live and learn after getting burned! g marie

User questions & answers

Question: How often should one change these specific filters
Answer: What size filter are you looking for? This listing has 3 choices - both of the choices that have a description of mpr 1550 are actually called allergen reduction filters & clearly state that they are mpr 1550. I use one of these sizes & always get the 1550. If you need 16X25X4 it's called allergen defense filter mpr 1000. I couldn't find any other statement in the description that listed the mpr - so to me it's unclear. You might want to contact amazon customer support to verify the mpr, but also, the product can be returned if it's not what you were looking for.
Question: I just bought a 1000 merv at a local store. They also had 3000 merv on sale. What's the difference between 1000, 2000 and 3000 and which is best
Answer: The one I purchased was 20x25x4. If you only have option for 1 inch thick, then it sounds like they are out of the 4 inch version.
Question: Are there 3 filters included in this product
Answer: When it gets dirty on the air intake side. Don't wait for it to get caked with dust as this will cut down on air flow and make your furnace/air conditioner work harder to reach your desired temperature. Filter vendors often recommend changing 4 times per year, but your mileage may vary depending on how much you heat and cool and the cleanliness of the air being moved. I change about 3 times per year, but I could go to twice. Do you change your car filter? How dirty does that get? Be sure the actual size of the filter is correct for your blower. Filtrete nominal sizes and actual sizes differ. I got stuck with 4 filters I can not use. I bought the size 16x25x4, but the end of the filter has the actual size: 16 x 24 1/2 x 4 1/2. the 4 1/2" dimension is too large to fit.
Question: Size
Answer: While I am not sure the Filtrete Allergen Reduction Filter is exactly the same as the Filtrete filter shown in the following commercial website, the table shows a MERV of 11 for a MPR of 1500. All the products seem to be 1" rather than 4." I don't know if that affects the MERV. http://www.iallergy.com/filtrete-air-filter-comparison.phpThe bottom of this commercial website page also describes the relationship of MERV, MPR, and FPR ratings for AC and furnace filters:http://www.bestfilters.com/AC-Furnace-Filters_c_605.htmlBased on my reading of the table, a MERV of 11 seems consistent with MPR of 1550.
