"Optimum HVAC LLC installed my new system on 8/6/25 and did an outstanding job. Paul and his team were on time, clean, professional, and polite. Before the install, Paul personally fixed an attic leak caused by a previous vendor’s poor work. Honest, skilled, and reliable — they’ve earned my business for good. Highly recommend!"

Very thorough! Good at communicating and keeping us up to date!

​just had our semi annual maintenance for our HVAC unit Chandler was our technician. Did a very thorough job. Highly recommend Optimum HVAC.

​Excellent evening service call with fast problem solving!!! Paul had us up and running within 30 mins. So happy to be cool again.

Optimum HVAC is the best HVAC service I have received while living in Wilmington for more than 10 years.

Great price

Great response time, professionalism, great work and the best pricing compared to everyone else I received a quote from. Highly recommend.

​Scheduled maintenance should be performed in early May and November of each year.
Crew was professional and efficient.

​Paul is so polite and dependable. He came right over and installed my wifi thermostat the very same day! Great job!!

​I was so thankful for Optimum HVAC. Paul was quick to respond, great communication during the process and met our needs without overselling us. I had two other large co only willing to replace inside and outside unit when the issue was only outside (compressor) which meant 2x the cost. I was told my outside unit wasn’t available but Paul had no problem getting my matching unit. I appreciate his honesty, consideration of cost and easy followup. I had a new unit within 4days installed! Would highly recommend.

Shows up on time. Very neat and tidy installation of a mini split unit in our mobile home. Quality work done in one day! Works closely with Fuse Home Electric. Would recommend in a heartbeat! Did I mention they clean up after themselves and left NO MESS??? Awesome.

Paul did a thorough check up & determined I needed a new thermostat. He’s very pleasant. I would recommend him to anyone that’s looking for service👍🏼👍🏼

​Optimum did an excellent job of installing duct and excellent in clean up. I highly recommend them.

​Priceing was less than we expected. Paul and Chandler were professional, on time and did a great job. I would recommend them to everyone I know

​The owner is absolutely a wonderful guy. Very professional and got in touch with me quickly. Would recommend

Paul and crew were on top of it from the first visit. Courteous, knowledgeable, helpful and straightforward. Pricing was very competitive with the other quotes. Communication was excellent and always delivered on promises. We are very happy and have found our new HVAC guys.

​Paul came out an provided me a quote. After checking a few other companies, I accepted the quote. Paul scheculed the service for a few days out and kept in constant communication. He arrived on the day scheduled with Chandler and Lee. All three did an amazing job from start to finish. They even swept out my garage floor when done. I could not be happier. Thank you so much for a seamless process!

Paul was very polite and done a very nice job and was on time.

Paul came to provide a second opinion. He explained the issues and provided sound advice on how to proceed. He was great at explaining the issues to a non-HVAC person.

Very responsive and very nice. Fully discloses all parts and service issues that need to be addressed and why.

I've been consistently impressed with the service provided by Paul during the routine six-month checkups. He is always punctual, professional, and extremely thorough in his work. He takes the time to explain what he's doing, ensures everything is running optimally, and never leaves a mess behind-always cleaning up completely before he leaves. It's clear he takes pride in his work, and that level of care and attention really shows. Highly recommend!

Very thorough and professional would recommend highly. 

From small service calls to full system and duct replacement, Optimum has provided me with top-notch service EVERY time I call. I highly recommend Paul and his team for any HVAC needs!

Very thorough and offered additional suggestions for long term maintenance. Very pleased.

Paul was on time, very quick and the system worked great when he was done!!

Great price

Great company! Excellent service.

​Excellent service. Fair prices. The type of people you can feel comfortable in your home. We highly recommend Optimum HVAC.

Very happy. Received the best price out of a few other contractors. The staff was very timely with answers to our questions, showed up when scheduled, and did a professional job. All details of the contract were clear and payment was not demanded up front like other contractors requested. Plan on using their services in the future.

Paul is very thorough and really understands HVAC systems. His prices are very reasonable and a pleasure to talk to.

They were able to get me in next day to evaluate uneven heating and cooling in my house. They gave me both a low-budget and a high-budget option for fixing the problem. Very reasonable. Would hire again!

I am a relatively new customer and needed to have my heating/cooling unit replaced. From the initial evaluation to the installation - work was done efficiently and on time. Very fair pricing. Optimum HVAC, Paul Hallenbeck, has been quick to respond to any needs and has provided excellent service. Great work ethic! Very professional, thorough and knowledgeable. Exceeded expectations!! I would highly recommend!
