Customer Reviews
I highly recommend Big Wave Designs Heating and Air. As a realtor, I am frequently in need of qualified contractors that deliver on timeline and professionalism. I personally wish there were more people with his work ethic, dedication to service, and attention to detail.
I met Derek 3 years ago when I purchased a home in Dewey Beach. As Derek installed the unit he was my go to guy for questions and concerns. He always took my call and answered any questions we had. When it came to my service he was proficient and friendly. He currently takes care of another property I have as well and did what the other contractor could not. He is efficient, courteous, polite and listens to what you have to say.
Big Wave is the best!! They responded to my call right away and gave me a time for the appointment. They showed up on time and wow! Were they quick about it. Went right to work and when they were done? Not a speck of dirt or dust. This was a problem call – and when they were done? problem solved I’ll never use anybody else. Thanks Derek and team
I have been a client of Derek for nearly 2 years. He replaced my HVAC unit on a very hot and humid day. In what should have taken 2 days, he worked an entire day and into late night to make sure the job was finished. I have asthma and severe allergies so it was crucial that I had air conditioning. In the next weeks, he also installed ductless mini-split HVAC in my sunroom. He has continued to maintain both systems timely and professionally. I rely on Derek for his sound expertise (he is quite knowledgeable regarding breathing issues), excellent customer service, and fair pricing, which are always important but essential for seniors. I highly recommend him. Thank you Derek.
I have used Derek on new home projects for over 4 years. He has always shown expert knowledge to do a good job.
He also has shown me over the years that he cares about doing the job right the first time. That is why I have been
satisfied with Derek’s work in the past and will keep using him in the future.
