David Duerr has been doing business with Commercial Construction Services Inc. for nearly six years. Amongst hundreds of subcontractors we work with annually, he is at the top of the list and is our ‘go-to’ HVAC subcontractor on our jobsites. His company is highly service-oriented, always on time and extremely competitive in pricing. David’s industry knowledge is paramount and I trust his assessment of our clients’ varying HVAC needs. On many occasions I have referred David to clients and friends alike and have never received anything but praise. I most highly recommend Duerr Heating and Air Conditioning for your HVAC needs.Glenn Morley
If you are looking for a great honest company, look no further than Duerr Heating and Air Conditioning. We have been using them for the past six years and they have been fantastic. There response time is fast. Their staff is professional and knowledgeable and they have even gone upon and beyond their specific HVAC duties in order to figure out issues we have had in the past. David, the owner knows everything about heating and air conditioning and their prices are very reasonable. I highly recommend Duerr Heating and Air Conditioning.Brittany N. Casarez
We have been using Duerr Heating & Air as a service vendor for our management and real estate clients for approximately 8 years, after a referral from one of our company owners. David has always been responsive to address urgent problems, and he has been willing to spend additional time with our owners answering questions and explaining concerns. He’s been willing to make repairs on older systems, which saves our clients money. His pricing is competitive as well. We have never had any complaints about his repairs or services.Christine Dickinson

I highly recommend them.
Dave and his team have been our HVAC solution for many years. They have proven themselves to be a trustworthy part of our team and are faithful in carrying out their services. We trust them to maintain our systems and provide recommendations so we can focus on our church operations instead of managing our HVAC needs.Brad Mortensen
I am a big fan of Duerr Heating and Air and have no hesitation recommending him to others. As a property manager responsible for over 150 properties, I have been able to use his services on many properties for several years. He’s skilled, prompt and honest. He deals well with tenants and his prices are reasonable and his invoices easy to understand. His jobs are always done completely, and I’ve never had a call-back about something not completed. I appreciate that when I ask his opinion to repair or replace I receive good information on costs and estimated remaining life-expectancy for current units. I have recommended David Duerr to friends, clients and other property managers.Joi Walker
