Holtkamp’s Commercial Heating Services

Holtkamp Heating & Air provides complete heating solutions for commercial spaces of all sizes. Our services include:

Commercial HVAC Installation

We handle entire HVAC system installations for new constructions or upgrade projects. Our experts will evaluate your space, recommend appropriate equipment, obtain permits, complete ductwork, install the units, and test the system. We work with budgets large and small.

Commercial HVAC Maintenance & Tune-Ups

Proper maintenance keeps your heating running smoothly and efficiently. Our technicians perform seasonal tune-ups to clean and inspect equipment, making any needed repairs or adjustments. We also offer maintenance agreements for year-round preventative care.

Commercial HVAC Repairs

Even well-maintained equipment eventually needs repairs. We have experts available for prompt service whenever your commercial heaters, furnaces, or boilers malfunction. We troubleshoot issues, obtain parts quickly, and work to minimize downtime.


Faulty ductwork causes inefficient air flow which compromises heating quality. We reconfigure ducts for optimal performance and install high-quality materials that resist leaks. Proper ductwork means evenly heated spaces.


For larger buildings, we design zoned HVAC systems that allow you to control temperatures in different areas or floors. Zoning saves energy while keeping occupants comfortable.

Fuel Conversions

If your energy costs are increasing, we can convert your system to use more affordable fuel. We handle natural gas, propane, electric, and dual fuel conversions.

Every project begins with an on-site assessment by our commercial HVAC specialists. We take measurements, evaluate your insulation, and examine current equipment. Then we recommend cost-effective solutions tailored to your specific needs.
