What Our Clients Have To Say

I love that when there's an issue, Daffan get's there quick! This summer and During the freeze when I panicked, they were by the phone 24/7 with reassurance and questions answered. My husband had passed and I was lost... Robert is my key guy and he comes every time. I love that...❤

Don Dearmore

We have been using Daffan for our heating and cooling needs for several years, and we wouldn't go with any other company. The service is topnotch, and their team is very professional. If your family or your pet has allergies, I recommend asking them about the air scrubber!

We recently switched over to Daffan from another company and could not be happier!! Kaitlyn was incredibly helpful and kept me up to date on the repair of my air conditioner and Will did a great job getting my house cooled again! You seriously can’t go wrong with Daffan. Everyone I spoke with was incredibly nice and knowledgeable. Plus they saved us money!

Lauren Kjornes

We have used Daffan since moving to Granbury- we kept seeing their truck in our neighborhood so we gave them a call. They are reliable, always on time, technician always calls before arrival, they always use shoe covers when entering the home and they are very accommodating in setting up service calls. We are very happy we found this professional company to maintain our heating and cooling systems.
Services: Cleaning, AC maintenance, HVAC maintenance

Sandra Schwartz

I have been a happy customer of Daffan for several years. Everything about them has been courteous and professional. All of the techs that came for semi annual maintenance communicated very well. They have been very helpful with any issues that I’ve had. AC systems are expensive and I felt they always had a fair cost for their services compared to others. They were good about giving options and helping decide what worked best for me.

Amy Knoll

Came home from shopping and my house was warm. Thermostat was black and wasn’t registering anything. Called Daffan and within 30 minutes they arrived and within another 45 minutes a/c was working and cooling again. Ryan was professional and knew what he was doing.

About Daffan Cooling & Heating

When David’s uncle originally started Daffan Mechanical in 1999 David saw his future. David began working in HVAC at the ripe old age of 18. He quickly worked his way to a highly skilled Master Technician. Naturally, when his uncle retired in 2011 he sold the business to David and his business partner, Tom. With much thought, reflection and prayer, they reinvented the core values and culture of the company to represent the future they had envisioned. Basing their decisions on Christian values the success of Daffan skyrocketed and they soon became known for exceptional service and care to their customers.

In 2019, we decided that Daffan Mechanical, and our familiar red & blue logo no longer matched the heart and intent of who our company had become. We took a year to find a look with the right feel. We are now “Daffan Cooling and Heating” with warm, traditional colors reflective of our values. And of course, it includes our beloved mascot, Doc.
