What Our Clients Have To Say

David W.

On call 24/7 Chris was spot on! We had a coil blowout for 5 days for the part, Chris came out 3 times to add Freon even on July 4th! Daffan has my vote!

Kent C.

Called them about my non-working AC, and they had a service tech on the way within three hours. Solved the problem and at a reasonable price. Great service. Thank you, Johnathan!

Michelle C.

Prompt service, Chris knew the antique heat and A.C. system I have and what to do to update it, heard good things from friends in Granbury and they do come to Weatherford.

Very Efficient, Fast, and Friendly. It is always a pleasant experience having my A.C. serviced. So thankful for them!

Floyd F.

I was extremely pleased with the Technician who came to our house and serviced our system. I think his name is maybe Eric. I forgot. I really want to mention him and give him the credit due. The past two servicemen have been outstanding. Prior visits were not at all. If possible ...

Cindy R.

Daffan Cooling replaced us with a new unit. Cut our electric bill in half and the service that we received from Chris has been excellent. He explains thoroughly what he is doing or finds, friendly and punctual.


Noticed our AC suddenly quit cooling. We couldn’t find any “obvious” reason so we called Daffan about 3:30 in the afternoon. They immediately got a tech scheduled to come check it out. They informed us then that there was a service fee of $99. (We are in Glen Rose). Just after calling, ...

Mckena H.

James was so nice & professional! He took the time to ask questions, did a thorough inspection, and even showed us how nasty our ductwork is & offered solutions. We’ll definitely continue using Daffan Cooling & Heating for all our HVAC needs.

Dominic P.

Daffan is Great… Very professional, efficient, timely, and reliable. We’ve come to know our technician Vickie and she is super thorough and treats our home with care like it’s her own.

Thorne T.

My heat pump was having a hard time maintaining a comfortable temperature during this last January cold spell, but Daffan came to the rescue… Found out that part of my mechanical heating system was not working, also my thermostat wasn’t performing the way it was supposed to. John was able to get ...

Lisa S.

Daffan are my hero’s! They came quickly to fix my heater during our first freeze/snow of 2024. Vicki is the best! She was very efficient, professional and nice. I was back on with heat in a short period of time; I’m very thankful to them.

Mike M.

What can I say? James was outstanding! Friendly, courteous, timely, and knowledgeable, even on a Saturday morning call. Not a “routine” issue to be sure. But James and the team had my family comfortable in a reasonable time considering the problem. Even dealt with the warranty items. Definitely worth the look.

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 & Heating” with warm, traditional colors reflective of our values. And of course, it includes our beloved mascot, Doc.
