Comprehensive Heating Solutions for Colorado Winters

A dependable heating system is non-negotiable during a Colorado winter. Our team specializes in a full range of heating services designed to keep your property warm, safe, and efficient when the temperatures drop. Whether you need an emergency repair, a routine maintenance check, or a complete system replacement, our certified technicians have the expertise to get the job done right.

  • Furnace Repair and Maintenance: A malfunctioning furnace can present itself in many ways—strange noises, a pilot light that won't stay lit, uneven heating, or a sudden spike in your energy bills. Our technicians are trained to diagnose and resolve any issue, from simple fixes to complex component replacements. We also emphasize proactive maintenance to prevent these problems from occurring in the first place. A seasonal furnace tune-up ensures your system operates at peak efficiency, extends its lifespan, and, most importantly, verifies its safe operation.
  • Heating System Installation and Replacement: If your old furnace is becoming unreliable or inefficient, it may be time for an upgrade. We provide expert guidance to help you select the right heating system for your property's size, layout, and your family's needs. We handle the entire installation process with precision, ensuring your new system is configured for optimal performance and energy savings from day one.

Reliable Air Conditioning Services for Weld County Summers

When the summer heat arrives, you depend on your air conditioner to provide a cool and comfortable indoor environment. A breakdown during a heatwave can be unbearable. Our team offers prompt and professional air conditioning services to ensure you stay cool all season long.

  • AC Repair and Tune-Ups: Is your AC unit blowing warm air, making unusual sounds, or cycling on and off too frequently? These are signs that it needs professional attention. Our technicians can quickly identify the root cause of the problem and perform lasting repairs. To avoid unexpected failures, we recommend an annual AC tune-up. This preventative service includes cleaning coils, checking refrigerant levels, and inspecting all electrical components to ensure your system is ready to handle the summer demand efficiently.
  • Air Conditioner Installation: An improperly sized or poorly installed air conditioner will struggle to cool your home, leading to high energy bills and premature wear. We specialize in professional AC installation, helping you choose a high-efficiency model that is perfectly matched to your home. We ensure a seamless installation process, giving you a reliable and powerful cooling solution you can count on for years to come.

Advanced Ventilation and Indoor Air Quality

The "V" in HVAC—ventilation—is a critical component of a healthy home that is often overlooked. Proper ventilation and air filtration are essential for removing pollutants, allergens, and stale air from your living spaces. This is especially important in Weld County's dry climate, where dust and allergens can become a persistent issue.

Our indoor air quality (IAQ) solutions are designed to help your family breathe cleaner, healthier air. We offer a range of services, including:

  • Duct Cleaning: Removing built-up dust, dander, and debris from your ductwork to improve airflow and reduce airborne irritants.
  • Humidifiers and Dehumidifiers: Installing whole-home systems to balance your indoor humidity levels for greater comfort and to protect your home's wood furnishings.
  • Air Purification Systems: Integrating advanced air purifiers and filtration systems that capture and eliminate bacteria, viruses, pollen, and other microscopic pollutants.

The Local Experts You Can Trust

Choosing an HVAC provider is about more than just technical skill; it’s about trust, reliability, and local expertise.

  • Weld County Focused: We live and work here. We understand the unique challenges of our local climate and are familiar with the types of homes and building codes in Greeley, Windsor, and the surrounding communities.
  • Experienced Technicians: Our team consists of licensed, insured, and continuously trained professionals who are passionate about their craft. They arrive on time, treat your home with respect, and are committed to solving your problem efficiently.

I called Halo when my water heater started leaking from the bottom. They responded quickly and reviewed my options for a new water heater. Steve was able to locate the particular water heater I wanted and had the old one removed and the new one Installed that day. I can't thank them enough for the prompt service. I highly recommend Halo and will use them again if the need arises. They were very courteous and professional.

Steve, the HALO technician, was great. He did a quick view of our furnace and could see it was malfunctioning. He was very transparent, showing me his initial findings, explaining how the furnace should work and trying a step to correct the problem. When that didn't work, he inspected the wiring more closely and found a crimped wire leading into the burner assembly. He replaced the wire and the furnace resumed normal operation. Thanks much, Steve!

They were on time, friendly and competent. In one day put in new furnace, took away old one. Permit was issued and city inspector said they did a really good job. I will use Halo for all my future HVAC needs.

I’m am so impressed with the quality and depth of service that I received. The details about what was being done and how the system works were so helpful to me and the most valuable as I know how to help diagnose my own system.
They tested everything and were able to diagnose my problems and get them fixed. This was after two other companies had tried to do this and failed
I would recommend them again to everyone who wanted expertise and high level skills and knowledge who will get the problem resolved.

Steve and Chernet literally saved our kennel dogs and puppies by repairing a heating system that was not designed to function in negative temperatures. They came up with a plan to keep the temperatures warm and monitored them throughout the night!! They did that! And did it all for an extremely fair price. We have had several other HVAC companies come to our business to“fix” our system. Nobody had ever been honest with us, and kept charging more and more each visit leaving us with a system that really was not designed to work properly. We will never use another HVAC company again. Halo has our business for life!!
