I am so excited to work with them. I was highly recommended from somebody in the Warren Building department. We gave them a call They asked us to email what we needed we did and they’ve already responded scheduled and are coming out this week hopefully.

Awesome Business to work with. Always willing to support their community and local schools!

I have been working on a major project that involved a large two story house in Highland Park and converting it into a commercial structure that would provide after school activities for doing homework, receiving a hot meal, using computers to excel their learning. This environment is a safe haven for school kids after the school day and during the summer between school years. It will also provide pre-school day care services. We needed the assistance of a commercial contractor who technical expertise in the field of geothermal systems. I was fortunate to have a friend who has handled my personal HAVC for 30+ years. He has many friends in the business who opened their reference file and I was able to make a contact with Nick who manages their services end of the business. He spent time walking through the two systems that heat and cool this structure. I was able to provide a history of our challenges since mechanical installation. I received a detailed quote from Nick which detailed all the services his team would provide to ensure the systems would run as designed and engineered. Once the contract is signed for the services quoted and services, I will be back to provide my feedback on the services performed.

De Cal has been a great resource for the City of Taylor. Great people, service, equipment maintenance and honest evaluations of potential issues. Give them a call to discuss your needs. You can't go wrong!

Decal has been nothing but a pleasure working with over the past few years. They are very good at any HVAC task you need. Very responsive, professional and thorough. Anytime, I have ever needed anything done for my clients they have been there. Tim and his staff are very nice loyal people. Would recommend them to anyone OH!

We have been working with De-Cal for years and they are very professional, helpful and accommodating.
