I have been involved with Mike, his sons, and Dillett Mechanical for over 28 years, and they have helped to make me a successful facilities director with their knowledge and skill in the HVAC industry. I believe that my career at Catholic Financial Life would not be as successful as it has been without Mike and his sons supporting the HVAC needs of Catholic Financial Life over the last 28 years.

We had Dillett Mechanical Service Inc. install the CATALYST retrofit solution on our roof top units. The results are amazing, showing a 50% reduction in HVAC electric use and 10% reduction in gas consumption.  We have also been very pleased with the visibility and reliability that the eIQ platform provides as well.

All of Independence Corrugated experiences in the past 10 years with Dillett Mechanical has been very positive, and to my knowledge this company has a history of timely and successful completion of all jobs. They do an excellent job, are always punctual, and offer competitive rates.

I have called for emergency services in the past after hours and on weekends and always get a call back within 30 minutes. Someone is usually sent out and makes all repairs as needed. There have been a few times that I called any phone number on anyone’s business card and they have gotten back to me or have had some one call me back to assist. They all have been great to work with on any services that have completed.

We have hired them on for all our Heating and A/C work. We also have used them for Sheet metal work. They have been very reasonably priced, and always do exactly what we ask of them.

I'm happy to recommend the services of Dillett Mechanical. A well above average company.

After using other firms, Dillett's customer service is unmatched. Dillett Mechanical is a true partner in making my business successful. "

"I want to thank you and your team for the smooth installation while I was on vacation. Also thank Brett for the fact that he found some serious concerns on the sheet metal and followed through to complete all repairs after hours."
