How Local HVAC Contractors Can Help You Meet 2026 Rules
March 19, 2026

Homeowners and business owners in Highlands Ranch, CO, are starting to hear more about new heating regulations coming in 2026, and for many people it raises a lot of questions. If your furnace is aging or you are planning a new heating system, these updates could affect what type of equipment you can install. At Certified Comfort Heating and Cooling LLC, we talk with local property owners every day who want to understand what the changes mean for their homes and businesses. As a trusted local HVAC contractor serving Highlands Ranch and the Denver Metro South area, we believe informed customers make the best decisions. This post breaks down the new rules, explains the best heating options available today, and shows how the right contractor can help you stay compliant while improving comfort and efficiency.



Why Colorado Is Changing Furnace Standards in 2026


Beginning January 1, 2026, Colorado will require new gas furnaces installed in the state to meet Ultra-Low NOx emissions standards. These rules focus on reducing nitrogen oxide emissions produced during combustion.

 

NOx emissions are a contributor to air pollution and can impact air quality across the Front Range. Because the Denver metro region has struggled with ozone levels for years, state regulators introduced these requirements to lower pollution from residential heating equipment.

 

Here is what the new rule means in practical terms:

  • New gas furnaces installed after January 1, 2026, must meet Ultra-Low NOx emission limits.
  • Older furnace models that exceed those limits will no longer be approved for new installation.
  • Existing furnaces can continue operating and be repaired.
  • The rule mainly affects homeowners and businesses replacing heating systems.

For many property owners in Highlands Ranch, this change simply means planning ahead. When the time comes to upgrade, working with a knowledgeable local HVAC contractor ensures the system you install meets the new standards.


How the 2026 Rules May Affect Furnace Replacements


If your furnace is already 10 to 20 years old, the timing of the new regulations could coincide with when you would normally replace it anyway.

 

Under the new guidelines, the traditional entry-level gas furnace models used for decades will be harder to find because many do not meet Ultra-Low NOx requirements. Manufacturers have already started adjusting their equipment lines to meet the new standards.

 

This shift may lead to:

  • New furnace models designed with cleaner combustion technology.
  • Increased availability of hybrid heating systems.
  • More homeowners considering electric heat pump options.
  • Higher demand for energy-efficient heating equipment.


While the regulations may sound complicated, most homeowners simply need a qualified heating installation contractor who understands the new equipment requirements and installation standards.


Why Cold Climate Heat Pumps Are Gaining Popularity


Across Colorado, many property owners are beginning to explore cold climate heat pumps as an alternative to traditional gas furnaces.

 

Modern heat pumps work differently than older systems. Instead of generating heat through combustion, they transfer heat from the outdoor air into your home. New cold climate models are designed to operate efficiently even when temperatures drop well below freezing.

 

Some advantages include:

  • Lower carbon emissions.
  • High energy efficiency ratings.
  • Eligibility for federal tax credits.
  • Compatibility with existing ductwork in many homes.

 

For Highlands Ranch homeowners looking to future-proof their heating systems, heat pumps are becoming one of the most attractive options local HVAC contractors recommend.


Hybrid Dual Fuel Systems Offer the Best of Both Worlds

Another popular solution is a dual fuel system, sometimes called a hybrid heating system.

 

This setup combines:

  • An electric heat pump for moderate temperatures.
  • A gas furnace that activates during extremely cold weather.

 

The system automatically switches between the two depending on outdoor conditions. This approach allows homeowners to reduce energy use while still maintaining reliable heating during Colorado’s coldest days.

 

Hybrid systems are especially appealing for homeowners who want to comply with evolving emissions standards while keeping the performance of gas heating when it is needed most.


Why Choosing the Right Heating Installation Contractor Matters

With new regulations and evolving heating technologies, professional guidance is more valuable than ever.

 

An experienced contractor will help you:

  • Choose heating equipment that meets 2026 emissions standards.
  • Determine whether a furnace, heat pump, or hybrid system is best for your property.
  • Ensure proper installation for long-term efficiency and safety.
  • Maximize available tax credits and rebates.

 

Heating systems are a major investment, and installation quality plays a huge role in performance. When systems are improperly sized or installed, energy costs rise and comfort suffers.

 

That is why many Highlands Ranch homeowners prefer working with trusted local HVAC contractors like Certified Comfort Heating and Cooling LLC, who understand local building codes, climate conditions, and equipment options.

The Importance of Regular A/C and Furnace Maintenance

June 26, 2024
As a homeowner, you rely on your HVAC system to keep you comfortable year-round. From providing cool air during hot summer months to keeping you warm and cozy in the winter, your A/C and furnace are essential to your daily life. However, like any other system in your home, your HVAC system requires regular maintenance to keep it running efficiently and effectively. In this blog post, we'll discuss the importance of regular A/C and furnace maintenance, as well as some tips on how to keep your system in top shape. Why Regular Maintenance is Important There are several reasons why regular A/C and furnace maintenance is important. First and foremost, regular maintenance can help prevent costly breakdowns. During a routine maintenance visit, our experienced technicians will inspect your system for any signs of wear and tear or potential issues. By catching these issues early on, we can address them before they turn into major problems that require costly repairs. Regular maintenance can also help improve the efficiency of your system. When your A/C and furnace are working at their best, they use less energy to heat or cool your home, resulting in lower energy bills. In addition, regular maintenance can help extend the lifespan of your HVAC system, which can save you money in the long run by delaying the need for a replacement. Finally, regular maintenance can help improve the air quality in your home. During a maintenance visit, our technicians will clean your system and replace any filters that have become clogged or dirty. This can help remove dust, dirt, and other pollutants from the air in your home, which is especially important if you or anyone in your family suffers from allergies or respiratory issues. Tips for Maintaining Your A/C and Furnace Now that you understand the importance of regular A/C and furnace maintenance, here are some tips to help you keep your system in top shape: Change your air filter regularly: One of the easiest and most important things you can do to maintain your HVAC system is to change your air filter regularly. A dirty air filter can restrict airflow, which can cause your system to work harder and use more energy. We recommend changing your air filter at least once every three months, but if you have pets or allergies, you may need to change it more frequently. Keep your outdoor unit clear: Your A/C unit's outdoor condenser needs plenty of space to operate efficiently. Make sure to keep the area around your outdoor unit clear of debris, such as leaves, twigs, and grass clippings. This will help ensure proper airflow and prevent the unit from overheating. Schedule regular maintenance visits: The best way to ensure your HVAC system is running at its best is to schedule regular maintenance visits with a professional HVAC company. During a maintenance visit, our technicians will inspect your system, clean your unit, and address any issues that need attention. We recommend scheduling a maintenance visit at least once a year, preferably in the spring or fall. Invest in a programmable thermostat: A programmable thermostat can help you save energy and money by allowing you to set your thermostat to automatically adjust the temperature when you're away from home or sleeping. This can help reduce your energy bills without sacrificing your comfort. Keep an eye (and ear) out for potential issues: If you notice any unusual sounds or smells coming from your A/C or furnace, or if you notice that your system is not working as well as it used to, it's important to address the issue as soon as possible. Ignoring potential issues can lead to costly repairs down the road. The Importance of Professional Maintenance While there are steps you can take to maintain your A/C and furnace on your own, it's important to remember the importance of professional maintenance. Professional maintenance visits provide a comprehensive inspection of your HVAC system that can help catch potential issues before they become major problems. Our experienced technicians have the tools and knowledge to diagnose and repair any issues that arise, ensuring your system is running at its best. In addition to the benefits of regular maintenance discussed earlier in this blog post, professional maintenance can also help ensure the safety of your home. Faulty A/C and furnace systems can potentially lead to fires, gas leaks, or carbon monoxide poisoning. By having your HVAC system inspected by a professional, you can rest easy knowing that your system is functioning safely and efficiently. Professional maintenance visits also help ensure that your system is running at its optimal efficiency, which can help save you money on your energy bills. A system that is running efficiently uses less energy to heat or cool your home, resulting in lower energy bills and less strain on your system. Conclusion Taking care of your A/C and furnace through regular maintenance can also help you save money in the long run. With proper maintenance, your system runs more efficiently, which means it uses less energy to heat or cool your home. This results in lower energy bills and less strain on your system, which can ultimately extend its lifespan and reduce the frequency of costly repairs. Additionally, regular maintenance can help improve the air quality in your home. Over time, dust, dirt, and other contaminants can build up in your HVAC system and circulate throughout your home. This can exacerbate allergies, asthma, and other respiratory issues. By regularly cleaning and maintaining your system, you can help ensure that the air in your home is clean and healthy. It's important to note that while regular maintenance is essential, it's not a guarantee that your system won't experience issues. However, by catching potential issues early on through regular maintenance, you can help prevent major breakdowns and costly repairs. And in the event that you do need repairs, our experienced technicians at The AC Guy are here to help diagnose and repair any issues with your A/C or furnace. In conclusion, regular maintenance is a critical aspect of keeping your A/C and furnace functioning properly. It can save you money on energy bills, improve the air quality in your home, and help prevent major breakdowns. Trust Certified Comfort for all your residential HVAC needs, and don't hesitate to contact us at (720) 751-4624 or info@certifiedcomfortpro.com to schedule your next maintenance visit.
Common Signs Your Furnace Needs Repair — Parker, CO — Certified Comfort Heating and Cooling LLC

Common Signs Your Furnace Needs Repair

June 26, 2024
Your furnace plays a critical role in keeping your home warm and comfortable during the colder months of the year. However, like any other system in your home, your furnace can experience issues over time. Being able to identify common signs that your furnace needs repair can help you prevent major breakdowns, save money on energy bills, and ensure that your home is warm and cozy all winter long. At Certified Comfort, we understand the importance of having a functioning furnace during the colder months, which is why we offer expert furnace repair services to keep your home warm and comfortable. In this blog post, we'll discuss common signs that your furnace may need repair, and how our experienced technicians can help diagnose and repair any issues with your furnace. Strange Noises One of the most common signs that your furnace may need repair is if you hear strange or unusual noises coming from your system. A furnace that is functioning properly should make only a low, steady hum. If you hear banging, clanking, or other unusual noises, it could be a sign of a loose or damaged component within your furnace. These issues can lead to further damage and a costly breakdown if left untreated. Increased Energy Bills There are a number of reasons why a malfunctioning furnace can result in increased energy bills. One common issue is a dirty air filter, which can reduce airflow and cause your furnace to work harder to heat your home. Over time, dust and debris can accumulate in your air filter, causing it to become clogged and restricting the airflow. This can result in your furnace using more energy than necessary to heat your home, leading to higher energy bills. Another potential cause of increased energy bills is a malfunctioning thermostat. If your thermostat is not functioning properly, it can cause your furnace to run longer than necessary, resulting in higher energy usage and increased energy bills. Additionally, if your thermostat is not properly calibrated, it may be giving incorrect temperature readings, causing your furnace to work harder than necessary to maintain the desired temperature. Poor Air Quality Your furnace plays a critical role in circulating air throughout your home. If you notice that the air quality in your home has decreased, it could be a sign that your furnace is in need of repair. A malfunctioning furnace can circulate dust, dirt, and other contaminants throughout your home, which can exacerbate allergies, asthma, and other respiratory issues. Weak Airflow Another common sign that your furnace may need repair is if you notice weak airflow coming from your vents. A furnace that is struggling to operate efficiently may not be able to produce enough warm air to properly heat your home. Weak airflow can also be a sign of a clogged air filter or a damaged blower motor. Yellow Pilot Light Your furnace's pilot light should be a consistent blue color. If you notice that your pilot light has turned yellow, it could be a sign of a gas leak or another issue within your furnace. A yellow pilot light can potentially lead to a dangerous gas leak, so it's important to have your furnace inspected by a professional immediately if you notice this issue. Short Cycling Short cycling is a common issue that can indicate a problem with your furnace. This refers to when your furnace turns on and off frequently, rather than running for longer periods of time. Short cycling can be caused by a variety of issues, such as a malfunctioning thermostat, clogged air filter, or a problem with the blower motor. Not only can short cycling lead to a less comfortable home, but it can also increase wear and tear on your furnace, leading to costly repairs down the line. Uneven Heating If you notice that certain areas of your home are colder than others, it could be a sign that your furnace is not functioning properly. Uneven heating can be caused by a variety of issues, such as a malfunctioning blower motor, clogged air ducts, or a damaged furnace filter. Not only can uneven heating lead to a less comfortable home, but it can also lead to higher energy bills as your furnace works harder to try to heat your home evenly. Age of Your Furnace Finally, it's important to consider the age of your furnace when assessing whether it needs repair. Furnaces typically last between 15-20 years, with older furnaces being more prone to issues and breakdowns. If your furnace is approaching the end of its lifespan, it may be time to consider replacing it. At Certified Comfort, we offer expert furnace installation services to ensure that your home is equipped with a reliable and efficient heating system. Conclusion Regular furnace maintenance can also help prevent these common signs of furnace issues from occurring in the first place. At Certified Comfort, we recommend scheduling a professional furnace tune-up at least once a year to ensure that your furnace is running efficiently and effectively. During a furnace tune-up, our experienced technicians will inspect and clean your furnace, check for any potential issues, and make any necessary repairs or adjustments. This can help prevent breakdowns, improve the efficiency of your furnace, and extend its lifespan. In addition to regular maintenance, it's important to choose a high-quality furnace for your home. At Certified Comfort, we offer expert furnace installation services to ensure that your home is equipped with a reliable and efficient heating system. We only use top-quality brands and products, and our experienced technicians will work with you to find the best furnace for your home and budget. With a high-quality furnace and regular maintenance, you can enjoy a warm and comfortable home all winter long. Don't wait until your furnace breaks down to address issues. By knowing the common signs that your furnace needs repair and scheduling regular maintenance, you can ensure that your furnace is running efficiently and effectively all winter long.
