“Rasmussen is our go-to company for all of our commercial HVAC and boiler needs. Nothing but the best service and support.”

Matt DeWall – JBS Prepared Foods CB

“I wouldn’t recommend anyone else… We had issues that other technicians couldn’t get to the bottom of, so Rasmussen came in and did the repair work and followed up with preventive maintenance. My work orders have been reduced thanks to you, and we are finally getting to a point where we can start concentrating on the proactive instead of the reactive.”

COOLING REPAIR FAQs

1. Why is commercial HVAC maintenance important for commercial buildings? Regular commercial HVAC maintenance helps prevent breakdowns, reduces energy costs, and extends the lifespan of your equipment. For commercial buildings, staying ahead of issues ensures reliable heating and air conditioning performance throughout the year. Proper maintenance also improves indoor air quality and energy efficiency, creating a healthier environment for occupants.

2. Do you offer HVAC services for commercial properties of all sizes? Yes. We provide repair, maintenance, and installation services for commercial properties ranging from small offices to large industrial facilities. Our technicians are knowledgeable and trained to work on all major systems and configurations, including rooftop units, chillers, and building automation systems.

3. How often should I schedule regular maintenance for my HVAC system? We recommend regular maintenance in the spring and fall to keep your heating and air conditioning equipment operating efficiently. Scheduling maintenance at least twice a year helps maintain comfort, prevents unexpected failures, and protects your investment.

4. Can your HVAC services help keep our building comfortable year-round? Absolutely. Proper maintenance and timely repairs ensure your systems deliver dependable heating and cooling, keeping your building comfortable year-round, even during extreme weather conditions. This includes checking thermostats, air filters, and refrigerant levels to optimize performance.

5. What can I expect from your technicians during a service visit? Our team provides friendly service backed by knowledgeable technicians who take the time to explain issues, answer questions, and make sure your needs are fully met. They also inspect electrical components, clean condenser coils, and check for refrigerant leaks to prevent future problems.

6. Do you work alongside roofing services when HVAC equipment is located on the roof? Yes. We frequently coordinate with roofing contractors to ensure rooftop HVAC units are protected, safely accessed, and properly reinstalled if needed. This helps prevent accidental damage and reduces the risk of unexpected breakdowns during or after roofing projects.

7. Can a new HVAC installation help improve air quality in commercial buildings? Absolutely. A properly designed and modern HVAC installation can significantly improve indoor air quality by enhancing filtration, ventilation, and humidity control. This creates a healthier environment for employees, tenants, and customers while also improving energy efficiency.

8. How can I avoid costly breakdowns with my heating system? Scheduling consistent maintenance for your heating system is the best way to avoid costly breakdowns. Our technicians inspect components, replace worn parts, check circuit breakers, and ensure your system runs efficiently so you’re not caught off guard by major repairs.
