Air Ducts
As the name suggests, gas water heaters use natural gas burned by a gas burner at the bottom of the tank to heat water. Common failures with gas water heaters include pilot light issues, faulty thermocouples, and other mechanical problems. Our team is fully trained to diagnose and resolve these issues quickly and efficiently.At Carroll Mechanical Services of Longmont, we provide full-service air duct installation, design, and repair—all at competitive rates. Our HVAC experts will evaluate your existing ductwork and consult with you on necessary repairs or duct replacements before beginning any work. We guarantee the job will be done right the first time.
Did you know that improperly installed or corroded air ducts can increase your heating and cooling costs by up to 25%? Call us today for an inspection and free estimate from the best HVAC company in Longmont, CO.
Gas Piping
Converting your appliances to natural gas adds comfort and value to your home—and natural gas is typically more affordable than electricity.
Carroll Mechanical Services (CMS) of Longmont has the experience and expertise to safely run gas lines from your existing natural gas main to your new appliances. Our team uses only the safest materials and performs a full inspection after installation to ensure your home is leak-free.
While threaded iron pipe has been the standard for years, flexible stainless steel tubing now offers a cost-effective and less labor-intensive alternative.
Natural gas also provides added resilience during power outages, allowing continued use of water heaters, stoves, and fireplaces. Did you know many BBQ grills can run on natural gas or propane? That means no more tank refills. Call CMS today for a free estimate.
Gas Leaks
If you smell gas, leave your home or office immediately. Call your gas company's emergency line and contact the fire department using a phone outside the building. Do not flip switches or use phones inside, as sparks could ignite gas.
Once you’re safe and authorities have been contacted, call Carroll Mechanical Services. We are fully equipped to locate and repair any gas leaks in your home or office. We also offer exterior gas line installation and HVAC repair services for detached garages, shops, and outbuildings.
Thermostats
Thermostats regulate the temperature in your home or business by controlling your furnace, boiler, or air conditioner. Older manual thermostats are often inefficient, keeping the temperature constant 24/7 unless manually adjusted.
Programmable thermostats are a simple solution to improve energy efficiency. Set them to warm your house before you wake or cool it before you return home, saving energy while improving comfort.
Carroll Mechanical Services installs and recommends a wide range of thermostats. Let our HVAC experts help you choose the right model for your Longmont-area property.
HVAC Inspections & Tuneups
CMS certified technicians provide comprehensive HVAC maintenance inspections for furnaces, boilers, air conditioners, and other heating and cooling systems.
We assess the integrity of your HVAC units, ductwork, and water heaters, inspecting all components for performance and efficiency. Based on the results, we offer personalized recommendations for HVAC services such as repair, maintenance, or replacement.
Comfort Control & Zoning
Zoning systems allow you to manage temperatures in different areas or floors of your home or business for greater comfort and efficiency.
Different areas of your house heat and cool differently—warm upstairs, cold basements, sunny south-facing rooms, and shaded north areas. A comfort control zoning system uses multiple thermostats and motorized dampers to direct airflow where needed.
This system helps ensure the basement stays warm in winter and the upstairs remains cool in summer—automatically. Contact the best HVAC company in Longmont, CO for a free zoning system estimate today.
Electronic Air Cleaners
Air purification needs vary from home to home. On Colorado’s Front Range, allergens, smoke from canyon fires, and other pollutants affect indoor air quality.
HEPA filters remove dust, pollen, allergens, and mold spores but may not capture smoke, fumes, or viruses. Other technologies, such as ionizers, carbon filters, and UV lamps, can complement HEPA systems for more complete purification.
Carroll Mechanical Services can help assess your needs and recommend the right air purification solution for your home or business.

What our customers are saying
Top Quality Serivce
"I was referred to Carroll Mechanical Services from an electrician I had used in the past. Although my issue turned out to be a minor blown fuse I felt that I received a full inspection for anything else that could go wrong. A cleaning of the fan and inspection of loose wires was a quick check, but it assured me that I was receiving top quality service."

Could Have Taken Advantage, But Didn't
"This week, our 19-year-old AC stopped working. We assumed it was done and would need to be replaced. The tech came out and checked it out. He could have easily told us we needed to buy a new unit, but instead, he fixed the small issue for much less. I very much appreciate that he could have taken advantage of us and didn’t. When this old system does need to be replaced, we will definitely have Carroll replace it. Thanks again!"
