Why Efficiency Ratings Matter for Wichita Homeowners
Efficiency ratings explained for homeowners is one of those topics that sounds complicated but makes a real difference once you understand it. If you own a home in Wichita or anywhere in Central Kansas, these ratings directly affect how much you pay to heat and cool your home every single month.
Here is a quick answer to get you started:
Home efficiency ratings at a glance:
| Rating | What It Measures | Higher or Lower is Better? |
|---|---|---|
| AFUE | Furnace fuel efficiency (%) | Higher is better (95% = top tier) |
| SEER2 | Air conditioner cooling efficiency | Higher is better (14+ minimum as of 2023) |
| HSPF2 | Heat pump heating efficiency | Higher is better (8.8+ minimum as of 2023) |
| HERS Index | Whole-home energy performance | Lower is better (0 = net-zero) |
| Energy Star | EPA-certified product efficiency | Certified = meets strict standards |
Kansas summers are hot and winters are cold. That means your HVAC system runs hard for most of the year. A furnace with a 95% AFUE rating converts 95 cents of every energy dollar into heat. An older 80% AFUE unit wastes 20 cents of every dollar right out the flue. Over a full heating season, that gap adds up fast.
The same logic applies to cooling. A SEER2 16 air conditioner can cut your summer cooling costs by 20 to 25% compared to a minimum-rated unit. For a typical household spending $500 on summer cooling, that is $100 to $125 back in your pocket every year.
Understanding these numbers is the first step toward smarter decisions — whether you are replacing aging equipment, shopping for a new system, or just trying to figure out why your utility bills keep climbing.
Decoding the Alphabet Soup: Efficiency Ratings Explained for Homeowners
When you start shopping for a new HVAC system in Derby or Maize, you’re suddenly hit with a barrage of acronyms. AFUE, SEER2, HSPF2—it feels like you need a secret decoder ring just to buy a furnace. Don't worry; we've been helping Central Kansas families navigate this "alphabet soup" since 1984.
The most important thing to look for is the bright yellow EnergyGuide label. This label is required by the Department of Energy (DOE) on all new units. It provides a standardized way to compare models. Think of it like the "Nutrition Facts" label on a cereal box, but for your home’s energy consumption.
Here is a breakdown of the big three ratings you’ll encounter:
- AFUE (Annual Fuel Utilization Efficiency): This is for furnaces. It tells you how much of the fuel (usually natural gas) is actually turned into heat versus how much is lost up the chimney.
- SEER2 (Seasonal Energy Efficiency Ratio): This measures how much cooling your air conditioner or heat pump provides per watt of electricity used over a typical cooling season.
- HSPF2 (Heating Seasonal Performance Factor): This is specific to heat pumps. It measures how efficiently the unit provides heat during the winter months.
It’s worth noting that in 2023, the industry shifted from SEER/HSPF to SEER2/HSPF2. This wasn't just a name change; the testing standards became much more rigorous to better reflect real-world conditions, such as the static pressure found in typical home ductwork. This transition represents about a 7% improvement in how accurately we measure efficiency.
If you’re considering a heat pump, you can Discover Energy Savings with Daikin's HSPF Rating Insights to see how these numbers translate into actual dollar amounts on your Westar or Kansas Gas Service bills.
Comparison Benchmarks (2026 Standards)
| System Type | Minimum Standard | High Efficiency | Premium Tier |
|---|---|---|---|
| Gas Furnace (AFUE) | 80% | 92% - 95% | 96% - 98.5% |
| Air Conditioner (SEER2) | 13.4 - 14.3* | 16 - 18 | 20+ |
| Heat Pump (HSPF2) | 7.5 - 8.8 | 9.0 - 10.0 | 10.5+ |
*Minimums vary slightly based on region and system type.
Heating and Cooling Metrics: What the Numbers Mean for Your Wichita Home
To truly grasp efficiency ratings explained for homeowners, we need to talk about BTUs (British Thermal Units). A BTU is a measurement of heat energy. Specifically, it’s the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit.
In HVAC terms, BTUs represent the "size" or capacity of your system. However, the efficiency rating tells us how much electricity or gas is required to produce those BTUs.
Modern high-efficiency systems often utilize variable-speed technology. Unlike older units that are either "all on" or "all off" (like a light switch), variable-speed systems can adjust their output to meet the exact needs of your home (more like a dimmer switch). This allows them to run longer at lower speeds, which uses significantly less energy and provides much more consistent comfort.
While a high rating is great, it’s only half the battle. To keep those ratings accurate throughout the life of the system, Essential HVAC Maintenance Tips for Your Furnace and AC are vital. Without regular cleanings and inspections, a 16 SEER2 unit can quickly start performing like a 13 SEER2 unit due to dirt and wear.
Efficiency Ratings Explained for Homeowners: SEER2 and Cooling
Living in the Wichita metro area means preparing for those 100-degree August days. Your air conditioner's SEER2 rating is its "miles per gallon" for the summer.
As of the 2023 DOE standards, all new air conditioning units must have a SEER rating of at least 14 (or 13.4 SEER2). But why stop at the minimum?
- Wichita Summer Humidity: High SEER2 units, especially those with variable-speed compressors, are much better at removing humidity from the air. In Kansas, it’s often the humidity that makes you feel miserable. By running at lower speeds for longer periods, these units pull more moisture out of your home, allowing you to feel comfortable even at a slightly higher thermostat setting.
- Electricity Consumption: A system with a SEER2 of 16 compared to one rated at 13 can reduce your cooling costs by 20-25% annually. If you’re spending $500 a summer on cooling in Bel Aire or Andover, that’s over $100 saved every year.
Understanding AFUE for Furnaces
In the winter, the script flips. We care about AFUE.If you have an older furnace with a metal flue pipe, it’s likely an 80% AFUE model. This means 20% of the gas you pay for is literally going up the chimney as exhaust.
High-efficiency furnaces (90% to 98.5% AFUE) use a secondary heat exchanger. This component captures the heat from the exhaust gases that would normally be wasted. Because this process cools the exhaust so much, it turns into liquid (condensate), which is why these are called "condensing furnaces." These units require PVC venting because the exhaust isn't hot enough to rise naturally out of a traditional chimney.
For a typical household in Newton or Hutchinson spending $1,500 a year on heating, upgrading from an 80% to a 95% AFUE furnace could save you roughly $237 per year. Over a 20-year lifespan, that’s nearly $5,000 in savings!
HSPF2: The Heat Pump Standard for Central Kansas
Heat pumps are becoming incredibly popular in places like Goddard and Valley Center because they provide both heating and cooling. The HSPF2 rating measures their heating efficiency.
- The 8.8 Minimum: After 2023, the new minimum for heat pumps is 8.8 HSPF2.
- Electric Efficiency: Because heat pumps move heat rather than creating it (by burning fuel), they can be incredibly efficient. High-efficiency models can maintain comfort even when Kansas temperatures drop.
If you’re curious about how a heat pump might perform in our climate, we recommend you Discover Energy Savings with Daikin's HSPF Rating Insights to see how modern technology has changed the game for electric heating.
Beyond the Label: Factors That Impact Real-World Performance
Here is a truth that many big-box retailers won't tell you: the number on the yellow tag is a "lab rating." Real-world performance depends on how the system is integrated into your specific home. At MJB Heating & Cooling, we emphasize that the most efficient furnace in the world will perform poorly if it’s installed incorrectly.
The Importance of Proper System Sizing
One of the biggest mistakes homeowners make is thinking "bigger is better." If an HVAC system is oversized, it will "short cycle"—turning on, blasting the house with air, and turning off before it can properly dehumidify or circulate the air. This leads to:
- Increased wear and tear on components.
- Higher energy bills (starting a motor takes more energy than running one).
- Hot and cold spots throughout the house.
Conversely, an undersized unit will run constantly, struggling to keep up with a Wichita heatwave, which also sky-rockets your bills. We use Manual J Load Calculations to ensure your system is sized perfectly for your home’s square footage, insulation levels, and window orientations.
Maintenance and Efficiency Longevity
Your home is a system. Even a high-rated HVAC unit can’t overcome:
- Poor Insulation: Up to 35% of your energy can be lost through a poorly insulated attic or drafty windows.
- Leaky Ductwork: If your ducts are leaking in the crawlspace or attic, you’re paying to heat and cool parts of the "outdoors."
- Airflow Restrictions: This is the big one. A dirty air filter increases "static pressure," forcing your blower motor to work twice as hard to move air.
To keep your system running at its rated efficiency, you need to know How Often Should HVAC Air Filters Be Changed. For most homes in Rose Hill or Park City, this is every 1–3 months, but it varies based on pets and allergies. For a deeper dive, check out our guide on How Often Should You Change Your HVAC Air Filter.
Factors Affecting Real-World HVAC Performance:
- Quality of the professional installation.
- Condition and sealing of ductwork.
- Thermostat placement (it shouldn't be in direct sunlight!).
- Attic insulation levels (R-value).
- Regularity of professional tune-ups.
- Cleanliness of the air filter.
Maximizing Your Investment with High-Efficiency Certifications
If you want the "Gold Standard" for your home, look beyond the basic ratings to these certifications.
Efficiency Ratings Explained for Homeowners: The HERS Index
The HERS Index (Home Energy Rating System) is like a golf score—lower is better. Developed by RESNET, it compares your home to a "Reference Home" (a home built to the 2006 energy code).
- A score of 100: Means the home performs the same as the 2006 reference.
- A score of 70: Means the home is 30% more efficient.
- A score of 0: Means the home is a "Net Zero" home, producing as much energy as it consumes.
According to a study by Freddie Mac, homes with better efficiency ratings can sell for 3% to 5% more than standard homes. It’s an investment that pays off both in monthly bills and future resale value.
Energy Star NextGen Standards
You’ve likely seen the blue Energy Star logo on your fridge or dishwasher. But Energy Star NextGen, rolled out in 2024, is the new frontier. These standards focus on:
- Electrification: High-efficiency electric heat pumps and water heaters.
- Smart Grid Technology: Systems that can communicate with the utility grid to save energy during peak demand.
- Future-Proofing: Requirements for EV charging readiness and induction cooking.
Frequently Asked Questions about Home Efficiency
How can I find the efficiency rating of my current HVAC system?
The easiest way is to look for the EnergyGuide label on the side of your outdoor AC unit or the front of your furnace. If that label is missing or faded, find the model number on the manufacturer's data plate. You can search that model number online or call us, and we can look up the original factory specs for you. A quick visual tip: if your furnace has a plastic PVC pipe for exhaust, it’s likely 90% AFUE or higher. If it has a metal pipe, it’s likely 80% or lower.
What is considered a "good" efficiency rating in 2026?
In today’s market, we consider a 95% AFUE furnace and a 16 SEER2 air conditioner to be the "sweet spot" for most Central Kansas homeowners. These ratings offer a great balance between the initial investment and long-term utility savings. If you are looking for the absolute best, look for 98% AFUE and 20+ SEER2 systems, which often feature fully modulating technology for maximum comfort.
Does a higher rating always guarantee lower utility bills?
Not necessarily. This is a common misconception. A 20 SEER2 air conditioner installed in a home with leaky ducts, no attic insulation, and an oversized blower will likely cost more to run than a properly installed 14 SEER2 system. Efficiency is about the entire home envelope. Think of your HVAC system like the engine of a car; if the tires are flat (leaky ducts) and the windows are down (poor insulation), the most efficient engine in the world won't get you good gas mileage.

- Wichita Summer Humidity: High SEER2 units, especially those with variable-speed compressors, are much better at removing humidity from the air. In Kansas, it’s often the humidity that makes you feel miserable. By running at lower speeds for longer periods, these units pull more moisture out of your home, allowing you to feel comfortable even at a slightly higher thermostat setting.
- Electricity Consumption: A system with a SEER2 of 16 compared to one rated at 13 can reduce your cooling costs by 20-25% annually. If you’re spending $500 a summer on cooling in Bel Aire or Andover, that’s over $100 saved every year.
Understanding AFUE for Furnaces
In the winter, the script flips. We care about AFUE.If you have an older furnace with a metal flue pipe, it’s likely an 80% AFUE model. This means 20% of the gas you pay for is literally going up the chimney as exhaust.
High-efficiency furnaces (90% to 98.5% AFUE) use a secondary heat exchanger. This component captures the heat from the exhaust gases that would normally be wasted. Because this process cools the exhaust so much, it turns into liquid (condensate), which is why these are called "condensing furnaces." These units require PVC venting because the exhaust isn't hot enough to rise naturally out of a traditional chimney.
For a typical household in Newton or Hutchinson spending $1,500 a year on heating, upgrading from an 80% to a 95% AFUE furnace could save you roughly $237 per year. Over a 20-year lifespan, that’s nearly $5,000 in savings!
HSPF2: The Heat Pump Standard for Central Kansas
Heat pumps are becoming incredibly popular in places like Goddard and Valley Center because they provide both heating and cooling. The HSPF2 rating measures their heating efficiency.
- The 8.8 Minimum: After 2023, the new minimum for heat pumps is 8.8 HSPF2.
- Electric Efficiency: Because heat pumps move heat rather than creating it (by burning fuel), they can be incredibly efficient. High-efficiency models can maintain comfort even when Kansas temperatures drop.
If you’re curious about how a heat pump might perform in our climate, we recommend you Discover Energy Savings with Daikin's HSPF Rating Insights to see how modern technology has changed the game for electric heating.
Beyond the Label: Factors That Impact Real-World Performance
Here is a truth that many big-box retailers won't tell you: the number on the yellow tag is a "lab rating." Real-world performance depends on how the system is integrated into your specific home. At MJB Heating & Cooling, we emphasize that the most efficient furnace in the world will perform poorly if it’s installed incorrectly.
The Importance of Proper System Sizing
One of the biggest mistakes homeowners make is thinking "bigger is better." If an HVAC system is oversized, it will "short cycle"—turning on, blasting the house with air, and turning off before it can properly dehumidify or circulate the air. This leads to:
- Increased wear and tear on components.
- Higher energy bills (starting a motor takes more energy than running one).
- Hot and cold spots throughout the house.
Conversely, an undersized unit will run constantly, struggling to keep up with a Wichita heatwave, which also sky-rockets your bills. We use Manual J Load Calculations to ensure your system is sized perfectly for your home’s square footage, insulation levels, and window orientations.
Maintenance and Efficiency Longevity
Your home is a system. Even a high-rated HVAC unit can’t overcome:
- Poor Insulation: Up to 35% of your energy can be lost through a poorly insulated attic or drafty windows.
- Leaky Ductwork: If your ducts are leaking in the crawlspace or attic, you’re paying to heat and cool parts of the "outdoors."
- Airflow Restrictions: This is the big one. A dirty air filter increases "static pressure," forcing your blower motor to work twice as hard to move air.
To keep your system running at its rated efficiency, you need to know How Often Should HVAC Air Filters Be Changed. For most homes in Rose Hill or Park City, this is every 1–3 months, but it varies based on pets and allergies. For a deeper dive, check out our guide on How Often Should You Change Your HVAC Air Filter.
Factors Affecting Real-World HVAC Performance:
- Quality of the professional installation.
- Condition and sealing of ductwork.
- Thermostat placement (it shouldn't be in direct sunlight!).
- Attic insulation levels (R-value).
- Regularity of professional tune-ups.
- Cleanliness of the air filter.
Maximizing Your Investment with High-Efficiency Certifications
If you want the "Gold Standard" for your home, look beyond the basic ratings to these certifications.
Efficiency Ratings Explained for Homeowners: The HERS Index
The HERS Index (Home Energy Rating System) is like a golf score—lower is better. Developed by RESNET, it compares your home to a "Reference Home" (a home built to the 2006 energy code).
- A score of 100: Means the home performs the same as the 2006 reference.
- A score of 70: Means the home is 30% more efficient.
- A score of 0: Means the home is a "Net Zero" home, producing as much energy as it consumes.
According to a study by Freddie Mac, homes with better efficiency ratings can sell for 3% to 5% more than standard homes. It’s an investment that pays off both in monthly bills and future resale value.
Energy Star NextGen Standards
You’ve likely seen the blue Energy Star logo on your fridge or dishwasher. But Energy Star NextGen, rolled out in 2024, is the new frontier. These standards focus on:
- Electrification: High-efficiency electric heat pumps and water heaters.
- Smart Grid Technology: Systems that can communicate with the utility grid to save energy during peak demand.
- Future-Proofing: Requirements for EV charging readiness and induction cooking.
Frequently Asked Questions about Home Efficiency
How can I find the efficiency rating of my current HVAC system?
The easiest way is to look for the EnergyGuide label on the side of your outdoor AC unit or the front of your furnace. If that label is missing or faded, find the model number on the manufacturer's data plate. You can search that model number online or call us, and we can look up the original factory specs for you. A quick visual tip: if your furnace has a plastic PVC pipe for exhaust, it’s likely 90% AFUE or higher. If it has a metal pipe, it’s likely 80% or lower.
What is considered a "good" efficiency rating in 2026?
In today’s market, we consider a 95% AFUE furnace and a 16 SEER2 air conditioner to be the "sweet spot" for most Central Kansas homeowners. These ratings offer a great balance between the initial investment and long-term utility savings. If you are looking for the absolute best, look for 98% AFUE and 20+ SEER2 systems, which often feature fully modulating technology for maximum comfort.
Does a higher rating always guarantee lower utility bills?
Not necessarily. This is a common misconception. A 20 SEER2 air conditioner installed in a home with leaky ducts, no attic insulation, and an oversized blower will likely cost more to run than a properly installed 14 SEER2 system. Efficiency is about the entire home envelope. Think of your HVAC system like the engine of a car; if the tires are flat (leaky ducts) and the windows are down (poor insulation), the most efficient engine in the world won't get you good gas mileage.

Why Efficiency Ratings Matter for Wichita Homeowners
Efficiency ratings explained for homeowners is one of those topics that sounds complicated but makes a real difference once you understand it. If you own a home in Wichita or anywhere in Central Kansas, these ratings directly affect how much you pay to heat and cool your home every single month.
Here is a quick answer to get you started:
Home efficiency ratings at a glance:
| Rating | What It Measures | Higher or Lower is Better? |
|---|---|---|
| AFUE | Furnace fuel efficiency (%) | Higher is better (95% = top tier) |
| SEER2 | Air conditioner cooling efficiency | Higher is better (14+ minimum as of 2023) |
| HSPF2 | Heat pump heating efficiency | Higher is better (8.8+ minimum as of 2023) |
| HERS Index | Whole-home energy performance | Lower is better (0 = net-zero) |
| Energy Star | EPA-certified product efficiency | Certified = meets strict standards |
Kansas summers are hot and winters are cold. That means your HVAC system runs hard for most of the year. A furnace with a 95% AFUE rating converts 95 cents of every energy dollar into heat. An older 80% AFUE unit wastes 20 cents of every dollar right out the flue. Over a full heating season, that gap adds up fast.
The same logic applies to cooling. A SEER2 16 air conditioner can cut your summer cooling costs by 20 to 25% compared to a minimum-rated unit. For a typical household spending $500 on summer cooling, that is $100 to $125 back in your pocket every year.
Understanding these numbers is the first step toward smarter decisions — whether you are replacing aging equipment, shopping for a new system, or just trying to figure out why your utility bills keep climbing.
Decoding the Alphabet Soup: Efficiency Ratings Explained for Homeowners
When you start shopping for a new HVAC system in Derby or Maize, you’re suddenly hit with a barrage of acronyms. AFUE, SEER2, HSPF2—it feels like you need a secret decoder ring just to buy a furnace. Don't worry; we've been helping Central Kansas families navigate this "alphabet soup" since 1984.
The most important thing to look for is the bright yellow EnergyGuide label. This label is required by the Department of Energy (DOE) on all new units. It provides a standardized way to compare models. Think of it like the "Nutrition Facts" label on a cereal box, but for your home’s energy consumption.
Here is a breakdown of the big three ratings you’ll encounter:
- AFUE (Annual Fuel Utilization Efficiency): This is for furnaces. It tells you how much of the fuel (usually natural gas) is actually turned into heat versus how much is lost up the chimney.
- SEER2 (Seasonal Energy Efficiency Ratio): This measures how much cooling your air conditioner or heat pump provides per watt of electricity used over a typical cooling season.
- HSPF2 (Heating Seasonal Performance Factor): This is specific to heat pumps. It measures how efficiently the unit provides heat during the winter months.
It’s worth noting that in 2023, the industry shifted from SEER/HSPF to SEER2/HSPF2. This wasn't just a name change; the testing standards became much more rigorous to better reflect real-world conditions, such as the static pressure found in typical home ductwork. This transition represents about a 7% improvement in how accurately we measure efficiency.
If you’re considering a heat pump, you can Discover Energy Savings with Daikin's HSPF Rating Insights to see how these numbers translate into actual dollar amounts on your Westar or Kansas Gas Service bills.
Comparison Benchmarks (2026 Standards)
| System Type | Minimum Standard | High Efficiency | Premium Tier |
|---|---|---|---|
| Gas Furnace (AFUE) | 80% | 92% - 95% | 96% - 98.5% |
| Air Conditioner (SEER2) | 13.4 - 14.3* | 16 - 18 | 20+ |
| Heat Pump (HSPF2) | 7.5 - 8.8 | 9.0 - 10.0 | 10.5+ |
*Minimums vary slightly based on region and system type.
Heating and Cooling Metrics: What the Numbers Mean for Your Wichita Home
To truly grasp efficiency ratings explained for homeowners, we need to talk about BTUs (British Thermal Units). A BTU is a measurement of heat energy. Specifically, it’s the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit.
In HVAC terms, BTUs represent the "size" or capacity of your system. However, the efficiency rating tells us how much electricity or gas is required to produce those BTUs.
Modern high-efficiency systems often utilize variable-speed technology. Unlike older units that are either "all on" or "all off" (like a light switch), variable-speed systems can adjust their output to meet the exact needs of your home (more like a dimmer switch). This allows them to run longer at lower speeds, which uses significantly less energy and provides much more consistent comfort.
While a high rating is great, it’s only half the battle. To keep those ratings accurate throughout the life of the system, Essential HVAC Maintenance Tips for Your Furnace and AC are vital. Without regular cleanings and inspections, a 16 SEER2 unit can quickly start performing like a 13 SEER2 unit due to dirt and wear.

You’ve likely seen the blue Energy Star logo on your fridge or dishwasher. But Energy Star NextGen, rolled out in 2024, is the new frontier. These standards focus on:
- Electrification: High-efficiency electric heat pumps and water heaters.
- Smart Grid Technology: Systems that can communicate with the utility grid to save energy during peak demand.
- Future-Proofing: Requirements for EV charging readiness and induction cooking.
Frequently Asked Questions about Home Efficiency
How can I find the efficiency rating of my current HVAC system?
The easiest way is to look for the EnergyGuide label on the side of your outdoor AC unit or the front of your furnace. If that label is missing or faded, find the model number on the manufacturer's data plate. You can search that model number online or call us, and we can look up the original factory specs for you. A quick visual tip: if your furnace has a plastic PVC pipe for exhaust, it’s likely 90% AFUE or higher. If it has a metal pipe, it’s likely 80% or lower.
What is considered a "good" efficiency rating in 2026?
In today’s market, we consider a 95% AFUE furnace and a 16 SEER2 air conditioner to be the "sweet spot" for most Central Kansas homeowners. These ratings offer a great balance between the initial investment and long-term utility savings. If you are looking for the absolute best, look for 98% AFUE and 20+ SEER2 systems, which often feature fully modulating technology for maximum comfort.
Does a higher rating always guarantee lower utility bills?
Not necessarily. This is a common misconception. A 20 SEER2 air conditioner installed in a home with leaky ducts, no attic insulation, and an oversized blower will likely cost more to run than a properly installed 14 SEER2 system. Efficiency is about the entire home envelope. Think of your HVAC system like the engine of a car; if the tires are flat (leaky ducts) and the windows are down (poor insulation), the most efficient engine in the world won't get you good gas mileage.

Customer Testimonials
Our A/C stopped working on a Sunday and due to health issues, we needed to find a service company available on a Sunday. I called MJB and left a message on their emergency voice mail. Within 10 minutes Tom Buck called me to hear my description of the symptoms. He was just finishing an appointment in Wichita and would be on his way to my home on the south end of Derby. He arrived within 30 minutes! From start to finish he was the perfect example of what you could ever hope for in an HVAC tech and a human being. His evaluation of our system inside and out was as thorough as I could ever imagine and once he was done with the repair, our system is running as well or better than ever. Well worth the price for the evaluation, parts, and labor. Thank you again Tom for an awesome experience.
Our AC went out during the hottest days of the year, and they were out next day! We have been jerked around by a shoddy home warranty for years. We finally had a chance to pick our own repair people, and MJB came highly recommended. I can see why! I was impressed with the honesty and speed at which they fixed our AC unit!
Our commercial building had a lightening/electrical strike and damaged our 20 ton AC unit. No one could find us a new unit before the end of September. Imagining going all of August and September with no AC in Kansas and working inside near 100 degree temps is less than thrilling. Dale and the team at MJB called around and saved the day. They had us a new unit 5 weeks earlier than other could promise and I now have happy employees. The unit is amazingly quiet, super cold and so much more energy efficient. Thank you for being our super hero!
Came out and installed my new furnace. Was very polite and affordable. They are very acknowledgeable and I highly recommend!
Thank you very much. We had our 1st warm night in 3weeks. MJB took the time and effort to find the real problem. And the employees were kind and thoughtful and explained things very well. I cannot thank you and all of MJB. Will recommend you highly. Thanks again Marjorie Herman Oxford Kansas
We had a new system installed and I was so impressed with how quick they were in come out and install it, in the middle of a hot summer day. They were so friendly & very professional. I had a small problem with a weird sound and they came over immediately and fixed it. Love them!
