Boulder
High-efficiency HVAC and home systems for Boulder residences.
Boulder homes are anything but uniform. From older houses near downtown to newer construction in North Boulder and foothills properties with more exposure to wind and weather, HVAC systems here need to be thoughtfully designed and properly maintained.
KJT Mechanical provides residential and light commercial HVAC services throughout Boulder. We focus on safe operation, long-term reliability, and clear recommendations that help homeowners make confident decisions without pressure.
Residential HVAC Services in Boulder
We service and install a wide range of heating and cooling systems commonly found in Boulder homes, including forced air furnaces, boilers, and modern heat pump systems.
Our residential HVAC services include:
- Furnace repair, maintenance, and replacement
- Air conditioning repair and installation
- Heat pump installation, service, and system upgrades
- Boiler service and replacement
- System diagnostics and troubleshooting
- Seasonal tune ups and safety inspections
Many Boulder homes have older equipment or unique layouts. We take the time to understand the system you have and how your home actually performs, not just what a manual says.
Heat Pumps and Electrification in Boulder
Heat pumps are especially popular in Boulder due to energy goals, available rebates, and the desire to reduce reliance on fossil fuels. When properly designed, modern cold-climate heat pumps can provide reliable heating and cooling throughout the year.
We help homeowners evaluate:
- Whether a heat pump is a good fit for their home
- Cold-weather performance expectations
- Backup heat options and system design
- Rebate and incentive opportunities
- Long-term operating and maintenance costs
If a heat pump does not make sense for your home or usage, we will be upfront about that. Our priority is matching the system to the building, not forcing a one-size-fits-all solution.
Light Commercial HVAC Services
In addition to residential work, we provide HVAC services for small commercial buildings throughout Boulder, including offices, retail spaces, and mixed-use properties.
Our light commercial services include:
- Rooftop unit diagnostics and repair
- Equipment replacement planning
- Preventative maintenance
- Safety inspections and system evaluations
We understand the importance of keeping systems running reliably while minimizing disruption to tenants and customers.
HVAC Safety Inspections and System Evaluations
Homeowners often contact us when something does not feel quite right. Uneven temperatures, unusual noises, frequent cycling, or rising utility bills are all signs that a system may need attention.
Our inspections focus on:
- Safe system operation
- Equipment condition and remaining life expectancy
- Efficiency and performance concerns
- Clear, written recommendations
If your system is safe and has life left in it, we will tell you. We believe trust is built by giving honest answers, even when replacement is not needed.

Service area FAQ
Do you service all neighborhoods in Boulder?
Yes. We service homes throughout Boulder, including North Boulder, South Boulder, downtown areas, and foothills properties. If you are unsure whether your home falls within our service area, feel free to call or text our office and we will confirm.
Are heat pumps a good option for Boulder's climate?
In many cases, yes. Modern cold-climate heat pumps can perform well in Boulder when properly designed and installed. Factors like insulation levels, home layout, existing ductwork, and backup heat options all matter. We help homeowners understand whether a heat pump makes sense for their specific home rather than pushing a one-size-fits-all solution.
Do you work on older homes in Boulder?
We do. Many Boulder homes were built decades ago and have unique heating systems, limited mechanical space, or a mix of upgrades done over time. We regularly work with older furnaces, boilers, and retrofitted duct systems and take extra care to evaluate safety, efficiency, and realistic upgrade paths.
Can you help with HVAC rebates and incentives?
Yes. Boulder homeowners may qualify for rebates and incentives depending on the type of system being installed, household income, and utility provider. We help identify available options and explain how they apply to your project so there are no surprises.
Do you provide second opinions on HVAC replacements?
Absolutely. Many homeowners contact us after being told they need a full system replacement. We are happy to evaluate the system, explain its condition, and let you know whether repair, maintenance, or replacement makes the most sense.
What should I do if my system is working but feels inefficient?
If your home has uneven temperatures, short cycling, higher utility bills, or comfort issues, it is worth having the system evaluated. These problems do not always mean replacement is needed. Often they point to airflow issues, control problems, or maintenance concerns that can be addressed.
